For high-pressure piping systems where multiple pumps are used together, the problem of water hammer in the piping system is even more acute. Water hammer is a pressure wave of the ever-changing flow in a pressure pipe, which is a hydraulic shock caused by a pressure rise or fall due to the change in the fluid flow rate in the pressure pipe. Water hammer is the combined result of the inc...

The working principle of the forged steel ball valve is to make the valve unblocked or blocked by rotating the valve stem. The ball valve is easy to switch, small in size, can be made into a large diameter, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and spherical surface are often in a closed state, which is not easy to be eroded by the medium, and...

(1) Selection principle of valves for water supply pipelines 1. When the diameter of the pipeline is less than 50mm, a globe valve should be used; When the pipeline diameter is greater than 50mm, gate or butterfly valves should be used; 2. When it is necessary to adjust the flow and water pressure, regulating valves and globe valves should be used; 3. For parts with low water flow resistance (such...
