Q:Assembling process of clip type check valve
Among them, the stainless steel clip check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface. In order to ensure that the valve can reach the appropriate position of the seat surface at any time, the disc is designed in the hinge mechanism so that the disc has enough swing space to make the disc real and comprehensive contact with the valve seat. The disc can be made of either metal or leather, rubber, or synthetic coverage, depending on performance requirements.
Q:Can the slow stop disc check valve close quickly?
Slow closing disc check valve does not turn off quickly."Slow closing" means slow closing and fast closing.The butterfly valve is mainly composed of a valve body, two semicircular discs, a return spring, an oil storage tank, a slowly closing small cylinder set, and a needle valve (a micro regulating valve). The principle relies mainly on the thrust of the imported medium and pushes the two discs smoothly.
Q:The check valve on the air pipe is installed in front of the fan and is there any difference in the back (direction is correct)?
Installed in front of the wind blowing, the top open check valveIt is difficult to install the check valve, which is installed on the rear by the force of air suction.
Q:What's the difference between a stop valve and a check valve? Is it a valve?
A check valve is a valve that automatically prevents the flow of fluid. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the exit side, the valve automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid flow backwards. The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow. Among them, the check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface.
Q:How to prevent the backflow valve of medium
The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the opposite direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.
Q:What is the purpose of installing a check valve in the air pipe before the fan?
The fan before the wind pipe installed on the check valve to prevent the fan after the ceased operation outside of the wind because of the air pressure is blown indoors because of the inverse.
Q:Can the check valve be used on the steam pipe?
The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.
Q:What does the check valve "H41F" mean?
According to the provisions of the JB/T 308-2004 valve type programming method:H== check valve4== connection: flange type1== structure form: lifting typeF== sealing surface material: fluorine plastic
Q:Is it necessary to install a check valve for household well pumping?
The filter screen is arranged at the water inlet check valve and is installed below the water pump
Q:What are the brands of check valves?
Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve.
