Q:Check valve does not automatically check back, how to adjust?
4 the vertical lift check valve shall be mounted on a vertical pipe.5, the lift type horizontal check valve shall be installed on the horizontal pipe.6. Do not check the weight of the valve in the line. The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system.
Q:The difference between backflow preventer and check valve
Plain and simpleBackflow preventer is double acting, better than check valve
Q:What happens when the check valve is broken?
Check valve is broken, there will be back water, down pressure, serious will produce pump reversal, burning motor
Q:What type of check valve should be installed before the suction pump?
Swing, turn, or automatic (note, anyway) can be.
Q:Check valve 1 inches DN25 what do you mean?
Crown valve pressFirst, an inch equals DN25That is, fixed values to estimate how large a pipeline isOne inch of check valve is mostly copper check valveThe price of I should be around 25 yuan
Q:Are check and check valves the same kind of thing?
The same thing is not the same as it is
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:Is the hdf41x 1.6Mpa a check valve?
The hdf41x 1.6Mpa is a backflow preventer with a check valve that is stronger and more complex than the function check valve.Backflow preventer (backflow preventer) is a device that uses a check element to prevent backflow of water supply pipe.
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:Circulating water check valve, I want to ask is not greater than DN600, you can use HBH747H hydraulic butterfly valve closed butterfly valve, less than DN600 of HD43X slow butterfly butterfly check valve, what does hydraulic check mean? Need hydraulic?
The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valveThis hydraulic pressure refers to the liquid pressure in the pipeline, not another pressure; the big caliber butterfly valves are small, and the small ones are all one-way valves. Another HB-HV hydraulic check valve, which is used on the oil circuit, the module and the operation circuit, you do not need.
We mainly produce various check valves (for example,single disc swing check valve,double disc swing check valve,ball check valve,lift check valve, butterfly valves,diaphragm valves ,ball valves and so on). Our products are widely used in municipal water and wastewater ,oil,chemical, food and other fields.Our entire valves are designed and manufactured according to ANSI (ASME), DIN, BS, JIS and other standard. Also, we ensure the best quality for customers, and our strict quality assurances systems are conducted throughout the entire production at the standard of ISO9001:2008 and CE.
