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

Caused by the brake disc brake on back wheel should not have four kinds of spaces possible: First, the foot brake 5 exhaust inlets, high pressure gas instinct Pai people the atmosphere, caused by gas-liquid master cylinder should not spring back to place, cause the system Oil will move the brake disc brake wheel cylinder piston top dead can not come back to places; are gas-liquid two disc brake master cylinder to the tubing plug, resulting in brake wheel cylinder piston can not come back to places; are three master cylinder of gas-liquid Can not spring back to their own spaces, brake fluid under high pressure gas, liquid should not return to the master cylinder reservoir chamber, resulting in brake wheel cylinder piston can not come back to places; are four wheel disc brake piston brake system because of moving fluid dirty or rusty Pistons Can not Back-bit card dead.

造成盘式制动器上的制动分泵不能回位有4种可能：一是脚制动阀5的排气口堵塞，高压气体本能排人大气，造成气液总泵的弹簧不能回位，导致制动油将盘式制动器的制动分泵活塞顶死而不能回位；二是气液总泵至盘式制动器的油管堵塞，造成制动分泵活塞不能回位；三是气液总泵的弹簧本身不能回位，制动液在高压气体作用下，不能回到气液总泵的储油室，从而造成制动分泵活塞不能回位；四是盘式制动器制动分泵活塞由于制动液太脏或活塞生锈卡死而不能回位。

Through the comparative analysis of the earth pressure calculated by the different calculation methods, it is known that when the earth pressure behind the abutment of the integral abutment bridge under the action of rising temperatures is calculated, it is not proper to use the m method to calculate the resistance coefficients of the abutment back wall and column earth while the resistance coefficient of the abutment back wall earth can be calculated by the Broms method. It is proper that the resistance coefficients of the earth of the abutment and pier piles should be considered by the p-y curve.

通过对不同方法计算的台后土压力的对比分析，得知：在计算升温引起的整体式桥台桥梁台后土压力时，桥台背墙及台柱土的水平抗力系数计算采用m法是不适合的；桥台背墙后填土的水平抗力系数可采用Broms法计算；土对台桩及墩桩侧的水平抗力系数按p-y曲线来考虑是适合的。

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。

The results show a reversed-flow region is formed at the tip of the pressure side due to the influence of the outside hot combustion gas and the pressure side tip thickness. The pressure gradient makes the coolant flow exit from the trailing edge slot first separates from the trailing edge cut-back, and then affected by the expansion wave, the coolant gas reattaches the cut-back of the trailing edge after passing a certain distance.

研究表明，由于外流和叶片叶盆尾缘厚度的影响，叶盆尾缘端部形成局部回流，叶片尾缘劈缝气体流出后受压力梯度的影响先抬起与叶背面分离，在流过一段距离后由于跨音速流膨胀波的作用，冷气流再次附着在叶背尾缘上。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
