2. Operation

A. Operating Principle (Ref. Fig. 10)

The upstream pressure of the valve is tapped through trailing edge probe (1) and overpressure valve (10). Then it is reduced between clapper (2) and its seat. The reduced pressure is then delivered into chamber (A) of regulator sub-assembly through calibrated hole (3). This pressure acts upon bellows which controls the position of clapper (2). The position of clapper (2) enables to build up a constant reduced pressure in opening chamber (C) of pneumatic actuator when unit covers the pressure regulation. The valve downstream pressure tapped through filter (5) is ducted to the closing chamber (D) of pneumatic actuator, between clapper (6) of distribution system and its seat. Clapper (6) is kept in the opening position by the downstream pressure. Since the reference pressure delivered, or not, to the opening chamber (C) of pneumatic actuator is constant, any variation in the downstream pressure brings about a change in the position of butterfly in order to keep the downstream pressure constant. The closing clapper (7) enables to distribute the reference pressure either in the opening chamber or in the closing chamber of the pneumatic actuator. In the event of IP air bleeding or HP overpressure conditions, ball valve (9) prevents the IP pressure from being admitted into the bellows of the regulator sub-assembly.

2. 工作原理

A. 工作原理（参见图10）

活门的上游压力经尾部引气管(1)与超压阀(10)引出，随后在阀芯(2)与阀座间降压。降压后的压力通过校准孔(3)输送至调节器子组件的腔室(A)输送至调节器子组件的腔室(A)。该压力作用于波纹管，进而控制阀芯(2)的位置。当装置执行压力调节时，阀芯(2)的位置使气动作动器开启腔室(C)内形成恒定的降压。经气滤(5)获取的活门下游压力被引入气动作动器关闭腔室(D)，位于分配系统阀芯(6)与其阀座之间。下行压力使阀芯(6)保持开启状态。由于输送至气动作动器开启腔(C)的基准压力恒定，下行压力的任何变化都会导致蝶板位置改变，从而维持下行压力恒定。关闭阀芯 (7)可将基准压力分配至气动作动器的开启腔室或关闭腔室。当发生IP空气泄漏或HP超压情况时，球阀(9)阻止IP压力进入调节器子组件的波纹管。

At engine idle speed, the HP regulating valve opens with a 0,55 bar rel. (8.00 psig) minimum pressure. The regulated pressure admitted into the opening chamber (C) of pneumatic actuator causes valve to open.

(2) HP regulating valve pressure control (Ref. Fig. 12)

In the event of an increase in engine speed, the HP bleed pressure exceeds a certain level (2,48 bar rel. (36 psig)); valve thus controls its downstream pressure to a constant value 2,48 bar rel. (36 psig). The downstream pressure causes the distribution valve of the regulator to open. This admits the downstream pressure into the chamber (D) of the pneumatic actuator. The opening chamber of the pneumatic actuator is submitted to a constant reference pressure. Any variation in the downstream pressure causes a change in the position of butterfly in order to keep the downstream pressure constant. The change in the differential pressure tends to modify the position of the butterfly, until the required value of the downstream regulated pressure is obtained.

(3) HP valve closing (transfer configuration) (Ref. Fig. 13)

From a sufficiently high engine speed, the IP bleed pressure causes the IP non-return valve to open, this to supply the bleed pressure regulating valve pneumatically. The IP pressure returns to the downstream side of the HP regulating valve and is then ducted to the closing chamber of the pneumatic actuator. This causes valve to close.

(4) HP valve closing (overpressure safety configuration) (Ref. Fig. 14)

If the HP bleed pressure exceeds a certain level (HP bleed pressure greater than 6,89 bar rel. (100 psig), this pressure admitted through the trailing edge probe causes the overpressure valve to open and plug the air inlet to regulator sub-assembly, causing chamber E of the regulator closing system to be evacuated, and in turn causing clapper (7) to move up in contact with its seat. The downstream pressure is thus admitted into the closing chamber (D) and the opening chamber (C) is vented.

(5) Pneumatic coupling of the HP regulating valve with the bleed pressure regulating valve.

If the bleed pressure regulating valve closes, the pneumatic link, between the pneumatic regulator of the bleed pressure regulating valve and the chamber (E) of the HP regulating valve regulator, causes the latter valve to close fully.

B. 工作配置

(1) HPV开启（参见图11）

当发动机怠速运转时，HPV在0.55巴（相对压力，8.00磅/平方英寸）的最低压力下开启。进入气动作动器开启腔室(C)的调节压力促使活门开启。

(2) HPV压力控制（参见图12）

当发动机转速上升时，高压引气压力超过设定值（2.48 bar rel. (36 psig)），活门即控制下游压力维持恒定值2.48 bar rel. (36 psig)。该下游压力促使调节器分配阀开启，使下游压力进入作动器腔室(D)。气动作动器的开启腔室承受恒定基准压力。下游压力任何变化都会导致蝶板位置调整，以维持下游压力恒定。压差变化将持续改变蝶板位置，直至达到所需下游调节压力值。

(3) HPV关闭（输送配置）（参见图13）

当发动机转速足够高时，IP引压导致IP单向活门开启，从而为PRV提供气源。IP压力返回至HPV下游侧，并被导入作动器的关闭腔室，促使活门关闭。

(4) HPV关闭（过压安全模式）（参见图14）

当高压泄压压力超过特定阈值（高压引气压力大于6.89巴相对压力（100磅/平方英寸）），该压力经尾缘引气管进入后，将开启超压活门并堵塞调节器子组件的进气口，导致调节器闭合系统腔室E排空，进而使阀芯(7)上移接触阀座。此时下游压力进入关闭腔室(D)，而开启腔室(C)则被排空。

(5) HPV与PRV的气动耦合。

当PRV关闭时，其气动调节器与HPV调节器腔室(E)之间的气动联接将导致后者完全关闭。

八、工作参数

九、在系统中工作原理

HPV装在引气系统的高压级，在怠速时，从高压级引气，HPV打开，当压力到达预设值时，HPV关闭，从中压级引气。

Air is generally bled from an Intermediate Pressure (IP) stage of the engine High Pressure (HP) compressor to minimize engine pressure losses. This is the normal engine air-bleed configuration.

– The IP stage is the 7th HP compressor stage. At low engine speeds, when the pressure from the IP stage is insufficient, air is automatically bled from a higher compressor stage (HP stage). This happens especially at some aircraft holding points and during descent, with engines at idle.

– The HP stage is the 10th HP compressor stage. Transfer of air bleed is achieved by means of a pneumatically operated-butterfly valve, designated HP bleed valve (4000HA).

为降低发动机压力损失，通常会从发动机高压（HP）压缩机的中间压力（IP）级引气，这就是发动机的常规引气构型。

-IP级是高压压气机的第七级。当发动机转速较低时（怠速），若IP级压力不足，系统会自动从更高一级的高压级引气。这种情况尤其在飞机停留点和下降过程中发动机怠速运转时发生。

-HP级是HP压缩机的第十级。通过气动作动活门（高压引气活门HPV，4000HA）实现引气。

When the HP bleed valve is closed, air is directly bled from the IP stage through an IP bleed check valve (7110HM), fitted with two flappers.

当HPV关闭时，空气会直接从IP级通过IP单向活门（7110HM）引气，该单向活门配有两片活门板。

When the HP bleed valve is open, the HP stage pressure is admitted into the pneumatic ducting and closes the IP bleed check valve. Air is then bled from the HP stage only. The HP bleed valve operates pneumatically and is connected by a sense line to a bleed pressure regulator valve (4001HA) and to a solenoid (4029KS) .

当HPV开启时，高压级压力被导入气动管道并中压级单向活门，此时仅从高压级引气。该HPV采用气动控制，通过感应管路连接至压力调节活门（4001HA）和电磁阀（4029KS）。

During cruise in normal bleed condition, the solenoid (4029KS) (installed in the fan compartment) is energized. This causes the solenoid opens to ambient the HPV PRV coupling sense line which lets the HPV close pneumatically. It avoid a permanent HP bleed due to low IP engine pressures.

在正常引气工况下巡航时，安装在风扇舱内的电磁阀（4029KS）通电。这使得电磁阀打开，使HPV PRV耦合感应管路与环境相通，从而允许HPV气动关闭。这样可避免因IP发动机压力过低而造成持续高压引气。

The HP Bleed Valve is a 4 in. dia. butterfly-type valve which operates as a shut-off and pressure regulating valve. The HP bleed valve is normally spring-loaded closed in the absence of upstream pressure. A minimum pressure of 8 psig is necessary to open the valve.

HPV是一种4英寸直径的蝶板类型的活门，兼具关断和压力调节功能。该活门在无上游压力时在弹簧载荷下通常处于关闭状态，需达到8 psi的最低压力才能开启。

The HP bleed valve pneumatically limits the downstream static pressure to 36 plus or minus 3 psig. It closes fully pneumatically when the upstream static pressure reaches 120 psig plus 5 psig or minus 10 psig. A pneumatic sense line connects the HP bleed valve with the bleed pressure regulator valve (PRV) in order to make sure that the HP bleed valve will close when bleed pressure regulator valve is controlled closed.

HPV通过气动方式将下游静压限制在36±3 psig。当上游静压达到120（+5，-10） psig时，该活门会自动完全关闭。为确保压力调节活门（PRV）关闭时HPV同步关闭，系统配置了气动感应管路，将HPV与PRV相连。

A solenoid is installed in the fan compartment. It is connected by a sense line to the HPV-PRV coupling sense line. When the engine is used with the old engine bleed air design, the Thrust Specific Fuel Consumption (TSFC) increases. This is because of low IP engine pressures give permanent HP bleed. To avoid this, during cruise with normal bleed condition,

– Wing Anti-Icing (WAI) not selected ON

– Normal bleed configuration (2 bleeds, 2 packs)

– Ps3 more than or equal to 110 psig

– Altitude over 15000ft

the solenoid is energized by the Engine Electronic Controller (EEC). It opens to ambient the HPV-PRV coupling sense line which lets HPV controlled close pneumatically.

风扇舱内安装有电磁阀，通过感应线与HPV-PRV耦合感应管路相连。当发动机采用旧式引气设计时，推力比燃油消耗率（TSFC）会升高。这是因为低进气压力会导致高压持续引气。为避免这种情况，在正常引气模式巡航时，需满足以下条件：

-机翼防冰系统（WAI）未开启、

-常规引气配置（2个引气口+2个packs）、

-Ps3压力表读数≥110 psi、

-飞行高度超过15000英尺。

此时发动机电子控制器（EEC）将向电磁阀供电，使其打开HPV-PRV耦合感应管路，从而实现HPV气动控制关闭。

(3) Detailed Description (Ref. Fig. 010)

The HP bleed valve contains three main parts :

– a valve body,

– a pneumatic actuator,

– a regulator assembly.

详细描述（参见图010）：

HPV包含三个主要组件：

-活门壳体，

-气动作动器，

-调节器组件。

(a) Regulation

The HP bleed valve upstream pressure supplies chamber (1) of the regulator through a jet to control the position of the clapper (2) and maintain constant air pressure in the HP bleed valve actuator opening chamber. The test intake is used for checking correct valve operation on the ground by directly supplying the regulator. The HP bleed valve downstream presure supplies the HP bleed valve actuator closing chamber through distribution clapper (3). Indeed when downstream pressure reaches the value determined by spring preloading.

调节系统：

HPV上游压力通过限流孔进入调节器的腔室(1)，用于控制阀芯(2)的位置，从而维持HPV作动器开启腔室内的恒定气压。测试进气口通过直接向调节器供气的方式，用于在地面检查活门的正常运行状态。HPV下游压力则通过分配阀芯(3)作用于作动器关闭腔室，当下游压力达到弹簧预加载设定值时，该阀芯将自动关闭。

(b) Opening/closing

Reduced pressure air supplies chamber (4) of the opening/closing sub assembly though a jet to control the position of clapper (5) against its lower seat position and allow the HP bleed valve actuator opening chamber supply with reduced pressure air. When chamber (4) is vented to ambient the clapper (5) leaves its lower seat position and reduced pressure air is allowed to supply the HP bleed valve actuator closing chamber (by unseating the springloaded ball).

打开/关闭

通过限流孔向打开/关闭子组件的腔室(4)输送调节降低后的气压，控制阀芯(5)顶住在其下阀座的位置，同时为HPV作动器的开启腔室提供调节降低后的气压。当腔室(4)与外界相通时，阀芯(5)脱离下阀座位置，调节后气压随即进入HPV作动器的关闭腔室（通过释放弹簧加载的球体实现）。

When upstream pressure reaches a specified value, clapper (6) vents to ambient chamber (4) of the opening/closing subassembly and plugs upstream pressure regulator inlet. This causes the HP bleed valve to close.

超压安全装置

当上游压力达到设定值时，阀芯(6)会向打开/关闭组件的环境腔室(4)泄压（放气），并关闭上游压力调节器的入口，从而导致HPV关闭。

(d) A safety valve attached to the cover protects the pneumatic actuator against overpressure in case of HP bleed valve failed open.

当HPV失效在开位时，安装在盖板上的安全阀可防止气动作动器因超压而受损。
