300X Slow Closing Check Valveby the main valve,check valve,needle valve,ball valvepolymorphicfilterand pressure gauges to form a hydraulically controlled receiver system. Utilizing hydraulic automatic operation, it can make the main valve get rapid opening or slow closing speed. Preventing the generation of water shock of water clock, in order to achieve the effect of slow-closing muffling. When the slow closingcheck valveWhen water is fed from the inlet end, the water enters the main valve control chamber through the micro filter, needle valve, and check valve, and then drains to the downstream through the ball valve. Because the needle valve opening degree is smaller than the ball valve opening degree, that is, the main valve control room drainage rate is greater than the speed of water intake, so the control room pressure is reduced, the role of the main valve disk at the lower end of the inlet pressure to open the main valve to the downstream water supply. When the pipeline stops supplying water, if the downstream water begins to flow back, part of the return water through the ball valve into the main control room, due to the check valve, the return water can not flow out of the main control room, causing the main control room to gradually increase the pressure, slowly close the main valve.

Performance Characteristics

  • Novel and reasonable structure, rational use of hydraulic principle cybernetics;
  • Smooth and reliable operation and high flow rate;
  • The valve flap is quick to open and slow to close, no water hammer impact (closing time is adjustable);
  • Good check sealing and long service life time;
  • Easy to install and maintain.
