Q:How can the fast closing noise check valve prevent water hammer?
Biaoguan valve that once the pump stopped, check valve spool in the spring or other auxiliary device for double end under the action of force balance in advance to the closed position, can greatly reduce the amount of water and initial water reflux falling height, water hammer force is calculated by gravity superposition, to reduce the amount of water is equal to the reduced gravity, but fell short height reduces the inertia time is relatively reduced speed, and can prevent the formation of destructive or reduce water hammer water hammer.
Q:Check valve is 150, why not put 150 of the smoke pipe?
DN150 check valve, it is possible that the internal path is less than the required value of 5mm-10mm. Therefore, the 150 outer diameter of the smoke pipe is not up.
Q:Fire hood fire check valve okay?
All smoke hoods are equipped with check valve, that is, when the hood is not used, the airflow outside into the kitchen
Q:An introduction to the check valve
The check valve, also known as reverse flow valve, check valve, back pressure valve, one-way valve. This kind of valve is automatically opened and closed by the force produced by the flow of the medium of the pipeline itself. It belongs to an automatic valve.
Q:What are the brands of check valves?
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.
Q:I also calculate each pump check valve and gate valve?
Should not be installed, if the installation is repeated, in fact, the original design has satisfied these functions! Gate valve is not necessarily a good thing! Nothing is better than fine! Make good use of the gate valve!
Q:Use of fire pump adapter even before you install a check valve
Multifunctional pump combination device usually comes with safety valves and check valves, usually 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 the pipes below plus a check valve, a higher temperature of the South may be suitable for direct use of non frozen.
Q:Installation position of household water meter check valve
It should be about 15 times before the table, about 300mm DN20.
Q:Is the check valve the same?
Same。 Call a difference; a thing. You come to our store to have a look.
Q:How to prevent the backflow valve of medium
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. 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. The swing check valve is almost completely open and the fluid pressure is almost unimpeded, so the pressure drop through the valve is relatively small. The check valve of the lift check valve is located on the valve seat sealing surface of the valve body. In addition to this valve disc is free to lift, like the rest of the cut-off valve, the fluid pressure valve from the valve seat sealing surface lift, medium return led down to the valve seat, and cut off the flow. Depending on the service conditions, the disc can be of all metal construction or in the form of a rubber pad or rubber ring on the valve frame. The same as the cut-off valve, lift check valve fluid through the channel is narrow, so the check valve by lifting the pressure drop than the swing check valve a little bigger, and swing check valve flow restrictions very little.
