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。

The cut-off valve with pilot valve without hand wheel, stem and lift nut inside will guide block and guide slot Butterfly Valves to guide sleeve, the disc-shaped disc to disc type bowl shape, and holes in the bottom of the flap valve to open, the valve cover of the original valve stem hole to hole diversion, because of increased pressure ring, ring, and the valve flap to class mortar, so that the flow passage separated the upper chamber cavity, external cavity, cavity, in the cavity and The external cavity increases with draft tube and stainless steel manual ball valve, flap valve in the cover plate and the center of the end of installing the spring, the upper flap valve install compression seal of the pressure ring, outside the cavity of the wall to open a Drainage holes.

带先导球阀的截止阀无手轮、阀杆和内升降螺母，将导向块与导向槽改为导向套，将盘形阀瓣改为类钵体形阀瓣，并在底部开阀瓣孔，电动蝶阀将阀盖原阀杆孔改为导流孔，因增加压环、密封圈和将阀瓣改为类钵体，使上通流腔分隔为上腔、外腔、内腔，在上腔与外腔的外部加设有导流管与不锈钢手动球阀，在盖板与阀瓣底的中心部加设弹簧，阀瓣上部加设压紧密封圈的压环，在外腔的壁上开有放水孔。

As a downstream piping system when the valve opens, reflux valve, when closed, the main medium used to prevent backflow to prevent the pump and drive motor reversal, as well as a container medium discharge; currently the most commonly used is the valve flap around the body Swing Pin rotation flap valve and the valve body along the vertical axis to move lift check valve, but the above two kinds of structures exist in the valve closed, medium speed back quickly from the largest drop to zero, inlet side of the pipe resulted in the rapid pressure rise, resulting Proportional Pressure Reducing Valves in damaging effects on the piping system of water hammer phenomenon, it is generally a diameter of valve production of 50 ~ 500 mm.

止回阀作为管道系统顺流时开启，逆流时关闭的阀门，主要用于防止介质倒流，防止泵及驱动电机反转以及容器内介质泄放；目前使用最普遍的是阀瓣围绕阀体销轴旋转的旋启式止回阀和阀瓣沿着阀体垂直中心线移动的升降式止回阀，但以上2种结构的阀门均存在关闭时介质倒流速度从最大迅速降为零，致使管道进水管一侧内压迅速升高，从而产生对管路系统有破坏作用的水锤现象，所以一般止回阀生产口径为50～500 mm。

Bellows Gate Valves However, in large differential pressure operating conditions, evaporation pressure has eased, the evaporator load requirements of the fluid volume decreased, but the actual situation the contrary, in the suction superheat unchanged, due to evaporation pressure has eased, the evaporator outlet pressure be reduced accordingly, pressure changes above and below the diaphragm, causing the main valve opening increases for increased fluid; but in a small pressure operating conditions, evaporation pressure rise, evaporator load demand for fluid volume increased, but the reality is that in the suction gas superheat unchanged, due to evaporation pressure rise, a corresponding increase in the evaporator outlet pressure, pressure difference above and below the diaphragm smaller, so that the main valve opening decreased for the reduction of liquid volume; in variable load is all about.

但在大压差工况下，蒸发压力降低，蒸发器负荷需求的液量减少，但实际情况相反，在吸气过热度不变的情况下，由于蒸发压力降低，蒸发器出口压力相应降低，膜片上下的压差变大，使主阀开度增大，供液量增加；但在小压差工况下，蒸发压力上升，蒸发器负荷需求的液量增多，但实际情况是在吸气过热度不变的情况下，由于蒸发压力上升，蒸发器出口压力相应提高，膜片上下的压差变小，使主阀开度减小，供液量减少；在变负荷下亦如此。
