Physical Reason Why Check Valve Born

  For high-pressure piping systems where multiple pumps are used together, the problem of water ham mer 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 incompressibility of the fluid, the inertia of the fluid motion and the elasticity of the pipe. In order to prevent the potential danger of water hammer in the pipelines, over the years, researchers use certain new structures, new materials in the design of the check valve. While ensuring the applicable performance of the check valve, the creative endeavor has made gratifying progress in reducing the impact force of the water hammer Check valve is a valve that relies on the flow of the medium itself to automatically opens and closes the valve plate. It is used to prevent the ba...

Air water generator | AWG System | AWG machines

Air water generator is a new multifunctional system that absorbs water from the humidity via condenser. After collecting water from the air,our machines process the water through the multi-stages filtration system and sterilization. Our AWG System is really a remarkable technology. It functions like an Air Purifier,Dehumidifier,Water Generator and Water Filtration System.All in one appliance. There 3 stages of carbon filtrations,which have high efficient absorbability.Meanwhile,TCR filter will add trace elements that are beneficial to the human body. What's more,it will balance the PH value and improve the taste of the water. Go through a serious and remarkable stage, the ro membrance will refine the water more carefully. There are home models and commercial machines to meet different requirements from our clients. The range of the water capacity is from 9 liters to 5000liters,which largely deal with various scenes. You can get fresh and drinking water whenever ...

Structural Features of Floating Ball Valve

  The ball of the floating ball valve is suspended. Under the pressure of the medium, the ball will move and press against the outlet side of the seal. The floating ball valve is only widely used for medium and low-pressure conditions because the pressure of the medium completely transfers the ball weight to the seal at the outlet. For the same reason, the design of the floating ball valve should focus on whether the material of the sealing ring can withstand the load of the ball and medium. Dvsvalve supply different types of floating ball valve, including bronze floating ball valve , forged steel ball valve and other customized valves. Features: 1. Floating ball valve has the smallest flow resistance among all types of valves; when the full-bore ball valve is open, the ball channel, body channel and connection pipe are of the same diameter, so the media can flow without loss. 2. Quarter-turn to open and close the valve fully, quickly; Floating ball valve also has ...
