At valve repair, import relief valve repair complex; import relief valve, control valves are used the body parts of the opening gate to regulate the flow of medium, medium pressure to lower pressure after the valve simultaneously with the role of regulation headstock of the opening piece, so that after the pressure valve to maintain at a certain range, the inlet pressure at the ever-changing circumstances, to maintain outlet pressure at setting the framework of the back to protect its pipelines, equipment, pressure, temperature stability ..................

在阀门维修中进口减压阀维修比较复杂；进口减压阀是采用控制阀体内的启闭件的开度来调节介质的流量，将介质的压力降低，同时借助阀后压力的作用调节启闭件的开度，使阀后压力保持在一定范围内，在进口压力不断变化的情况下，保持出口压力在设定的范围内，保护其后面管道、设备的压力、温度的稳定

Safety valve is opened by the automatic import of hydrostatic pressure relief protection device, Balanced Bellows Safety Relief Valvess, Closed it is the pressure vessel, one of the most important security annex, which function is: When the container pressure exceeds a certain value, the pressure on media's own auto - Open the valve to quickly discharge a certain amount of media.

安全阀是一种由进口静压开启的自动泄压防护装置，它是压力容器最为重要的安全附件之一，它的功能是：当容器内压力超过某一定值时，依靠介质自身的压力自动开启阀门，迅速排出一定数量的介质。

When a sudden power failure or accident or normal pump stops when the pump stops, the valve inlet water velocity to reduce stress Agency, the valve plate also fall, when its velocity is zero (that is, inlet flow rate is zero Department), large valve plate because of its own gravity and rapidly turn off (time 3s ~ 5s), the majority of water to prevent backflow, when the valve before and after the formation of a water pressure, water stress, on the one hand through the small valve at the bottom of the three slot for pressure relief vent pressure. 4 water stress from the bypass tube into the cavity patch up the control room (this process for the suction pressure chamber that can effectively absorb the energy of water), when water stress on cavity than inferior vena cava, the pressure of water promote the diaphragm down mobile , the current cavity pressure of water being squeezed out all the small valve plate slowly drop back to standby status, the process time to ease closure adjustable (3s ~ 150s), then the valve has been fully closed, watertight.

当突然停电或事故停泵或正常停泵时，阀门进水口处压力水流速降低，大阀板也随之下降，当其流速为零时，大阀板由于自身重力而迅速关闭（时间3s～5s），可防止大部分水倒流，此时阀门前后形成一种水压差，压力水一方面通过小阀板底部的三条泄压槽进行泄压。4）压力水从旁通管进入膜片控制室上腔（此过程为吸压腔，能有效吸收一部分水能量），当上腔压力水大于下腔时，压力水推动膜片往下移动，当下腔压力水全部被挤出来时，小阀板缓缓下降，恢复到待机状态，此过程中缓闭时间可调节（3s～150s），届时阀板已全部关闭，滴水不漏。

While there are different types of relief valve designs, the basic principle is that when the pressure in the equipment exceeds the relief valve's set pressure, the relief valve will open and remain open until the pressure is reduced below the set pressure, after which the relief valve recloses to seal the system.

安全阀虽然有不同种类的设计，但他们的基本原理是一样的，当设备里的压力超过安全阀的设置压力时，安全阀就会打开卸压，直到设备里的压力降低到低于设置压力后安全阀会重新合上，并保持系统封闭。

As the "Hydraulic safety Closed Spring Loaded Low Lift Type-High Pressure Safety Valve valve," has two levels pressure relief function and pressure from low to high pressure limiting function; with limited pressure relief and anti-corrosion properties of good stability and reliability advantages of the patented product may greatly enhance and expand power systems and hydraulic equipment hydraulic mine support equipment, quality and performance.

由于&气动液压安全阀&具备二个级别卸压功能和从低到超高压力的限压功能；具备限压卸压稳定可靠和防腐性能好的优点，本专利产品可极大地提升和拓展液压动力系统和液压设备矿井支护设备的品质和性能。

It works as shown in Figure 2b, when the work when the system is high pressure, EF mouth also in high pressure, high pressure Balance Valves unloading of oil equivalent one-way valve open and the unloading valve 3 1 contact; when the pressure exceeds the safety valve unloading having a set pressure, unloading relief valve to open, the return oil through oil path b to uninstall the spool 4, left, unloading Safety valves valve spring to overcome the spring force 5, unloading spool shifted to the right, EF population of high-pressure oil through direct discharge port T Dutch tank.

其工作原理如图2b所示，当工作系统处于高压状态时，EF口也处于高压状态，高压油打开等值卸荷单向阀3与卸荷安全阀1接触；当压力超过卸荷安全阀调定压力时，卸荷安全阀开启，其回油经油道b到卸载阀芯4左端，克服卸载阀弹簧5的弹簧力，卸载阀芯右移，EF口的高压油经T口直接卸荷油箱。

Then the influence of flow, pipe length, setting pressure of relief valve and stiffness coefficient of main valve spring on the water hammer peak pressure at the instant of fuel pistol closing was studied according to the detected pressure signals. Finally, the relatively accurate gas-liquid separation value and critical cavitation pressure value of the system was obtained by frequency analysis and wavelet analysis.

根据测得的压力信号，对燃料枪关闭瞬间流量、管长、溢流阀调定压力以及主阀弹簧刚度对水击效应引起的峰值压力的影响进行研究，并通过频率分析方法和小波分析方法较精确地获得系统的气液分离值和临界汽蚀压力点。

Then the influence of flow,pipe length,setting pressure of relief valve and stiffness coefficient of main valve spring on the water hammer peak pressure at the instant of fuel pistol closing was studied according to the detected pressure signals.

该测试平台不仅能实时可靠地对系统压力进行定量诊断与识别，同时还可以为燃料泵送系统的性能优化提供依据。

A Type CG-3 212°F fusible metal plug may be used, but only when in combination with the Type CG-7 pressure-relief valve., ':

CG-3 212°F型易熔塞也可以用，但只能和CG-7型减压阀组合使用。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
