1. Product Overview
300X slow closing check valve is installed in the high-rise building water supply system and other water supply system of the pump outlet, to prevent the media back, water hammer and water hammer phenomenon of intelligent valve. The valve has 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, fast closing and slow closing to eliminate water hammer, so as to prevent the generation of water hammer and stop pump.
Working principle:
When the valve supplies water from the inlet end, the water enters the main valve control room through the micro filter, needle valve and one-way valve, and then drains to the downstream through the ball valve. Because the opening of the needle valve is less than the opening of the ball valve, 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 is reduced, 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 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 cannot flow out of the main control room, causing the main control room to gradually increase pressure and slowly close the main valve.
2. product features
1. The 300X slow-closing check valve consists of a main valve, a one-way valve, a needle valve, a ball valve, a micro-filter and a pressure gauge. The use of hydraulic automatic operation, can make the main valve to get the best opening or closing speed. To prevent the occurrence of water stroke in the water clock, in order to achieve the effect of slow closing silencing.
2. This product uses hydraulic self-control, does not need other devices and energy, easy maintenance, opening and slow closing smoothly.
3. This series of valve products are widely used in high-rise buildings, living areas and other water supply network systems and urban water supply projects.
