300X slow closing check valve overview: slow closing check valve is installed in the high-rise building water supply system and other water supply pump outlet, to prevent media backflow, water hammer and water hammer phenomenon of intelligent valves. The valve combines electric valve, check valve and water hammer eliminator three functions, which can effectively improve the safety and reliability of the water supply system, and the slow opening, closing speed, slow closure to eliminate the technical principle of water hammer integration to prevent Open the pump water hammer and stop the water hammer. Just operate the pump motor hoist button, the valve can be opened and closed automatically in accordance with the pump operating procedures, flow, pressure loss. 300X slow closing check valve structure features and uses: 300X slow closing check valve by the main valve, check valve, needle valve, ball valve, microfilter and pressure gauge composed of hydraulic control system. The use of hydraulic automatic operation, the main valve can be the best opening or closing speed. Prevent the water hammer hit the water hammer in order to achieve the effect of slow closing silencer. 300X slow closing check valve hydraulic self-control, do not need other devices and energy, easy maintenance, open and slow and steady closure. 300X slow closing check valve valve products are widely used in high-rise buildings, living areas and other water supply pipe network systems and urban water supply projects. 300X Slow closing check valve works: When the valve from the inlet end of the water, water through the micro-filter, needle valve, check valve into the main valve control room, and then through the ball valve to the downstream drainage. Because the needle valve opening is less than the ball valve opening, that is, the main valve control room drainage speed greater than the inlet speed, so the control room pressure decreases, acting on the main valve plate inlet pressure to open the main valve to the downstream water supply. When the pipeline stops water supply, if the downstream water starts to flow back, a part of the backflow water enters the main control room through the ball valve. Due to the function of the one-way valve, the backflow water can not flow out of the main control room, causing the main control room to gradually increase pressure, slowly closing the main valve .
