Butterfly oblique seal multi-function check valve introduction

Butterfly oblique sealing multi-function check valve is mainly used for water supply and drainage piping system, at the exit from the slow, slow closure, check the role of anti-reverse flow of media to protect the safety of pumping station equipment. In structure, the valve uses a three-eccentric structure, oblique dish plate. In the valve material, the body / plate using 0235-A (welding, should be dealt with), the valve stem selection 2Cr13 stainless steel. In addition, the VALVES are stainless steel laminated (plate-laminated, body-built 316 steel) to ensure very reliable sealing of the valve. The valve adopts the hydraulic slow closing cylinder control system to effectively control the valve to automatically stop at three levels when the pump is stopped, shut 70% off quickly, slow down 20% and finally slow off 10%, effectively eliminating water hammer pressure. The valve is opened to rely on the pressure on the medium to open the pump naturally, shut down to rely on the medium's own back pressure and the working force of the electric actuator. Pump starts, the valve automatically opens under the action of the pump water, external multi-stage adjustable damping hydraulic cylinder piston rod retracted; pump operation, the butterfly plate will be stable at a larger opening smooth work; normal stop pump or When the pump is stopped, the board will be closed and closed slowly. In addition, the valve has a truncation function, the valve with manual closing function, not with the pump linkage. The valve completely solves the energy consumption problem of the existing butterfly check valve in the open state, prevents the impact vibration caused by the quick opening speed, solves the problems of supplying, discharging and exhausting of the piston rod during lifting, and provides the required The damping of the damping. The valve has the functions of slow release, slow closing and check-back, and functions as a "valve" on behalf of "multiple valves"; the valve has a clever concept so that the cushioning device has the advantages of simple structure, small size, short valve body and light weight, Easy to adjust to obtain the required damping. Valve "butterfly oblique sealing device" technology, opening and closing without friction, improve the sealing performance, effectively extending the service life; effectively reduce the design of water damage, minimize head loss, energy efficient; to achieve three slow Closed back, the valve closed in three phases to achieve the valve closing action, thus effectively protecting the pipe network and pump safety. In addition, the valve set electric control mechanism, with the pump to achieve electrical linkage. Users configure the appropriate instrumentation and control components, the valve can be delayed to open the valve, the pressure on the open valve, forced open the valve and other functions. If the user needs, you can also configure the adjustable electrical equipment used to regulate the flow. Butterfly oblique seal multi-function check valve during use, through the runner does not appear sediment and other debris accumulation and jamming, which affects the normal operation of the valve. This has a positive effect on the effective protection of pumps and pipes and prolonging their service life. In addition, compared with the traditional water-based check valve, the product can effectively save energy and effectively save resources and operating costs.
