Usually, the fluid under pressure to make the disc of the valve opening, and exported from flow inlet side to side.When the import side pressure is lower than the export side, the disc under the action of fluid pressure and gravity itself automatically to channel closed, to prevent fluid backflow.Disc in different ways, according to the check valve is mainly divided into the lift, swing and butterfly 3 classes.Lift check valve body more similar to cut-off valve body, the fluid resistance is larger.This type of check valve for high pressure small, often using the disc and spherical shape.Swing check valves on the fluid resistance is small, suitable for medium and small size, low pressure, large diameter pipelines, often on the channel baffle valve set up multiple disc, become more disc type.Similar to the shape of the butterfly check valve and butterfly valve.It has simple structure, small resistance for fluid.Check valve such as closing too fast, could cause a liquid in the liquid pipe, noise, and even cause the damage of valve parts.In order to avoid this kind of situation, when need can choose buffer function of the check valve, extend the closing time.

Q:Pump adapter need check valve?
General in the flange pipe interface or who is interface settings simple check valve, safety valve is white, but does not apply to the north, the northern cold, need to separate in the pipeline is provided with a check valve, a higher temperature of the South without suitable for direct use may be frozen.
Q:What type of check valve should be installed before the suction pump?
Swing, turn, or automatic (note, anyway) can be.
Q:Should the pressure gauge be mounted before or after the check valve at the back of the pump?
If the pressure gauge is installed before the check valve, the normal pressure will be displayed only when the pump is running. The pressure value displayed at the pump is not consistent with the actual pressure of the pipe.
Q:Three forest electric water heater, hot water flow is small, check valve dripping problem?
You called the check valve is also called one-way valve, safety valve has non-return function, also known as relief valve, also can be said as a pressure reducing valve. About 7 kilograms of pressure will generally not Water Leakage, Water Leakage, because of the small water valve and is a function of the filter, open the inlet connecting, you will find a safety valve on the water inlet filter gasket, cleaning.There's no more than 100 in that thing. We're all dead. Send you one.You said that Sanlin manufacturers on this level? Too oftenThe safety valve must be fitted, or the tank will be under great pressure and the hot water will run into cold water.Relief valve function: release, check, filter
Q:My hood inside outside blow valve pops ringing
Please take the pipe at the hood of the range hood for 15 cm or more, and then blow the wind. Note that the installation of fixed, do not affect the valve sag.
Q:What is the HH44X-16 H of the double acting slow closing check valve? Can you explain it in detail?
2, micro resistance, slow closing check valve, also known as check valve, its role is to prevent the medium back in the pipeline. The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents. Suitable for cleaning medium, not suitable for medium containing solid particles and viscosity.
Q:Is the overcurrent valve a check valve?
The overflow valve is just a pipe overflow pronounSuch as decompression, flow valve, butterfly valve, flow valve and so onActually, they are all called in the front wordsTherefore, can not be replaced to illustrate
Q:The air pipe is equipped with a check valve
The weight of the valve or the gravity of gravity to maintain the valve in the open state of balance, the principle of the same, are heavy torque control of the door opening and closing. Inside and outside the air pressure to destroy the balance, automatic door opening and closing control. An example of simply closing a valve plate by gravity, as in a vertical check valve (Dan Liufa) in a water supply pipe.
Q:The working principle and structure description of the mute check valve
When the valve is in use, the medium flows according to the direction of the arrow.1, when the medium according to the provisions of the direction of flow, the valve by the media force, is open; the medium back, due to weight and disc valve by the medium reverse force, so that the sealing surface of the valve flap and valve seat sealing and closed, to prevent the media counter to.2, the body and valve sealing surface using stainless steel surfacing.3, the length of the valve according to the provisions of GB12221-1989, flange connection size according to the provisions of JB/T79-1994.
Q:The principle of the check valve
The function of the check valve is to allow the medium to flow in one direction only, and to prevent the flow in the opposite direction
