Q: Check valve symbols?: 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. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself.

Q: Check valve H15B-16 DN25 is that product?: Screw swing multi valve check - nominal pressure 1.6Mpa, product caliber 25mmOur company has production!

Q: God, can you explain to me in detail 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.

Q: How can the check in the faucet prevent water from flowing backwards?: Not to prevent backflow, is able to quickly shut the water, for triple bathtub, can effectively stop the conversion between the bath and small shower water, there is a spring, when the water pressure will be water, a small amount of Water Leakage was shut up

Q: Check valve h44h-25p what does that mean?: H- stainless steel4- flange connection4- rotary single structure check valveH sealing material is Cr13 stainless steel25- pressure 2.50MPAP-18-8 stainless steelH44h-25p= stainless steel flange connection, swing type single check valve pressure 2.50MPA valve body, material 18-8 stainless steel

Q: What is the reason that the valve is not used for a period of time?Anonymous browsing | 314 times: 1, the valve at both ends of the road must be blocked, there is dry ventilated room. Such as long-term storage, should always check rust corrosion.2, the valve should be cleaned before installation and eliminate the defects during transportation.3, the installation must be carefully checked on the valve signs and nameplates are in line with the use of requirements.

Q: How do I install the pump outlet check valve?: Because the check valve is easy to be damaged, therefore, the check valve shall be installed near the pump outlet, and a shut-off valve (usually ball valve or gate valve) is arranged on the top of the check valve, so that it is easy to overhaul. In order to facilitate the check valve before disassembly pressure relief, the valve itself is not equipped with a net valve, should be installed between the check valve and the shut-off valve with pressure relief valve.

Q: What type of check valve should be installed before the suction pump?: second body cover seal welded forged steel check valve, connected by this form of valve, the valve body and the valve cover are connected by screw, all welded seal, the advantage of no leakage.

Q: How to install the water pipe check valve?: The pipe type check valve is mostly in the form of clip type installation, which is suitable for the place where the installation distance is not enough!Understand more direct CALL I ~ user name is my Unicom number
