300X slow closing check valve
一. Product overview
300X slow-closing check valve is an intelligent valve installed at the pump outlet of high-rise building water supply system and other water supply systems to prevent medium backflow, water hammer and water hammer. The valve combines three functions of electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system, and integrate the technical principles of slow opening, quick closing, and slow closing to eliminate water hammer to prevent The water hammer when the pump is turned on and when the pump is stopped.
When the valve feeds water from the inlet end, the water enters the main valve control room through the micro filter, the needle valve, and the one-way valve, and then drains to the downstream through the ball valve. Because the needle valve opening is smaller than the ball valve opening, that is, the drainage speed of the main valve control room is greater than the water inlet speed, so the pressure in the control room decreases, and the inlet pressure acting on the lower end of the main valve disc opens the main valve to supply water downstream.
When the pipeline stops supplying water, 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 one-way valve, the backflow water cannot flow out of the main control room, causing the main control room to gradually increase the pressure and slowly close the main valve. .
2. Product features
1. The 300X slow-closing check valve is composed of a main valve, a check valve, a needle valve, a ball valve, a micro filter and a pressure gauge to form a hydraulic control takeover system. Using hydraulic automatic operation, the main valve can get the best opening or closing speed. Prevent the water hammer from the water hammer, so as to achieve the effect of slow closing and silencing.
2. This product uses hydraulic self-control, does not require other devices and energy, is easy to maintain, and opens and slowly closes smoothly.
3. This series of valve products are widely used in high-rise buildings, living quarters and other water supply pipe network systems and urban water supply projects.
