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。

On the basis of improved continuous flow equation,the mathematical model that expresses the interrelationship of the liquid pressure,the movement of plunger piston and the pump barrel clearance were setup,and simulating model s of the liquid instantaneous pres.

根据改进的连续流方程，建立了泵筒内液体压力、柱塞运动规律与柱塞泵筒间隙之间相互关系的数学模型，从而建立了泵筒内液体瞬时压力与泵示功图的仿真模型。

The simulated distribution of the volume fraction of vapor phase under different outlet pressure and the variation of the cavitation flow ratio indicate that the intensity of cavitation is varied with the outlet pressure of the jet pump when driving pressure and suction pressure are fixed.

模拟所得到的不同出口压力下的气相体积分数分布以及汽蚀流量比的变化表明：当射流泵工作压力与吸入压力固定时，射流泵出口压力越低，汽蚀流量比越小，同时流量比越接近汽蚀流量比，空化也越严重。

The piston pump has many kinds of structures; the variable displacement axial piston pump with a swash plate is a better kind among them and could best match the requirements of large flow, high pressure, and small volume. It also has a advantage of easily realizing the control of flow and pressure.

柱塞泵有许多结构形式，斜盘式轴向柱塞变量泵是诸多柱塞泵结构中结构比较先进，最能适应现代作业大流量、高压力、体积小要求的柱塞泵结构形式；并且对于实现多种流量、压力控制有着较大的优势。

Centrifugal pump flow rate as a pressure change much, while the volume of pump flow rate as a pressure change was small, and the centrifugal pump shaft power decreases with the head of the law to improve the contrary, the volume of the pump shaft power with the pressure increase and increase.

离心泵流量随压力改变很大，而容积泵流量随压力改变却很小，与离心泵的轴功率随扬程提高而减小的规律相反，容积泵的轴功率随压力的提高而增大。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
