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 the check valve and the stop valve?
The check valve is not the same as the cut-off valve. The difference between them is mainly that the structure is very different.Check valve is a one-way valve, automatically prevent reverse flow of fluid, no knob, can not be artificial blocking forward flow.The valve has a knob, and the controller can control the forward flow. Because of its special structure, the fluid can not flow backwards even if there is no artificial valve.
Q:How does the check valve work?
Only one-way flow, blocking the valve seal, liquid can not be returned.
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:The self-priming pump with check valve (check valve, water valve)?
Both, but there are good or bad points, good seal, with a spring, the general is a piece of rubber plus a piece of iron, plus a check valve is feasible
Q:Does the check valve differ in front of the water meter and press it behind the water meter?
Check valve is mainly to prevent water backflow, backflow, easily lead to water damage
Q:What is the difference between globe and check valves?
1. check valve is called one-way valve, the role is to prevent fluid flow, can not be adjusted, can not be closed.2., the cut-off valve can be used to regulate flow, can be closed, can be closed.
Q:Why is the water ring vacuum pump equipped with check valves?
The check valve is a one-way valve, the instantaneous vacuum of the stopping pump is higher than the pump cavity, and the gas enters the pump cavity from the exhaust port, and the water pressure is connected to the vacuum pipeline, and the function of the check valve is to prevent water from entering the pipeline
Q:The working principle and structure description of the mute check valve
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:What is the function of the small check valve on the deep well pump?
This valve is to stop the pump when the intake, through the intake of water to cut off the backflow, to prevent water from being returned to empty, the air can not enter the valve above the part of the water pipe, rest assured
