Pump and discharge block valves, suction strainer, pressure gauge and relief valve.
当关断井口时，阀操作的程序必须是：先MSSV，后由于易熔塞回路气源意外损失将引起所有地面，地下阀闭合。
The degree that the strainer blocks up may show out on the piezometer in filtering oil vehicle running process, respond to the strainer cleaning or changing a strainer in time (to have all filtering oil vehicle special use but be for replacement's using while pressure reaches 0.35 MPa, order if necessaries is other), Gage pressure continues rising when exceeding 0.4 MPa, just meeting proper motion opens a relief valve, part oil liquid essence fliteration does not pass henceforth, returns to an oil pump directly attract the oil cavity, therefore filtering oil vehicle output rate of flow just is able to come down, to play filter oil vehicle's to avoiding damaging role.
在滤油车运行过程中滤芯堵塞的程度可在压力表上显示出，当压力达到0.35MPa时，应及时清洗或更换滤芯(备有滤油车专用滤芯可供更换用，如需可另外订购)，表压继续上升超过0.4MPa时，安全阀便会自行开启，此后部分油液不经过精过滤，直接回到油泵吸油腔，所以滤油车的输出流量便会下降，以起到避免损坏滤油车的作用。
In view of the problem that the pressure of the feed water pipe network of the booster pump station at the clean water reservoir of waterworks drops when the reservoir retains water while the demand for water supply during the peak time of water consumption cannot be met, a ball float relief valve controlled by a pilot valve has been developed by applying the principle of setting the pressure of the feed water system with a pilot valve, with which the said problem is properly resolved.

A pump with too large a capacity wastes energy as excess fluid passes through the pressure relief valve.
句中的fluid其实就是油，在机械的泵中，绝大多数都是用的油。
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。
