1), The slow-closing system has excellent performance and is not affected by the medium in the pipeline. The valve disc is quickly closed first and then slowly closed, which can prevent ring-breaking water hammer. 2), rubber buffer, smooth opening and closing, no vibration, no noise. 3), rubber soft seal, good sealing performance, wear resistance and long service life. 4), the flow resistance is smaller than the old-fashioned check valve, and it has obvious energy saving effect 5) The valve body adopts a full channel and streamlined design, with small fluid resistance and large flow.
Introduction
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 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, quick closing and slow closing to eliminate water hammer, preventing The generation of water hammer when the pump is turned on and water hammer when the pump is stopped.
Structural features
300X slow-closing check valve consists of main valve, one-way valve, needle valve, ball valve, micro filter and pressure gauge to form a hydraulic control takeover system. Using hydraulic automatic operation, the main valve can get the best opening or closing speed. To prevent the generation of water hammer, in order to achieve the effect of slow closing and silencing.
This product uses hydraulic self-control, does not require other devices and energy, is easy to maintain, and has stable opening and slow closing.
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.
