FAQ

Tap water tank with vertical and horizontal check valve.
Extrusion includes seat and plate or piston designed to prevent the valve slamming. Additional material added to the seat produces two extrusion zones. Try to squeeze the fluid out of these areas and slow down the valve during rapid closing. But there is a price to pay for that. The limited gap increase region is an ideal site for collecting small solid particles. The squeeze pressure protection for controlled closure, due to the collection of solids, may cause additional problems, unless the gap is sufficiently extruded, the solids can be ejected. A narrow seal may shatter a fragile solid, such as coal. The extrusion zone tends to expand the width of the available valve seat and reduce the ability of the valve to crush solids. This effect must be considered, taking into account all the characteristics of the related solids.s
What's the difference between check valves and non-return valves?
Other check valves (check valves), such as blowdown check valves,Civil air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.s

Is the check valve in or behind the gate valve? Why?
The exit of the general pump is the first soft connection (shock absorber), followed by the check valve, and then the partition valve (such as butterfly valve, gate valve, cut-off valve, etc.), this is not the final answer.The question is interesting, and no corresponding information has been found in the relevant standards. We have also discussed the related issues, but differences of opinion is relatively large, the advantages of 1, first installed check valve installed after the valve or butterfly valve, check valve, can be protected, especially in a parallel pump, when the pump does not start, another pump starts when the impact force is gate valve or butterfly valve bear, disadvantages: gate valve or check valve who will protect? There have been a case of butterfly valve is broken. 2, first installed gate valve or butterfly valve installed after the check valve, advantages: can protect the butterfly valve or gate valve, the impact on the check valve to bear. Disadvantages: check valve who will protect, check valve by pressure difference switch, if the high pressure high pressure pipe, pump, if the flow is not stable, so check valve will repeatedly switch, will affect the check valve life. Personal opinion: check valve, check valve performance now have changed, many are using the slow closing check valve, so the impact force is two aspects to bear, because exports are not fully open the valve or butterfly valve, so you can put in check after the gate valve or butterfly valve valve. If not the slow closing check valve installed in the valve or the best after the butterfly.s

Is the check valve behind or behind the gate valve? Why?
Thank youPlease install it in frontWhat about the front?s
Is it necessary to install a check valve in the piston refrigeration compressor?
