H42X lifting bottom valve is a kind of energy-saving valve, which is generally installed at the bottom of the underwater suction pipe of the pump. It restricts the liquid in the pump pipe from returning to the water source, and it can only enter and leave. There are many water inlet products on the valve cover. The stiffeners are not easy to block, and the micro-resistance slow-closing butterfly check valve is mainly used in pumping pipelines. The role of water channels and supports. Calibers are single, double, and multi-lobed. Flange and thread connections are available. .
Structure and principle:
The bottom valve is composed of valve estimation, valve disc, valve cover, bushing, sealing ring and other parts. Water from the water source enters the valve body from the valve cover. Under the pressure of the fluid, the valve disc opens the water. The pressure quickly closes the valve flap, and the liquid will not be poured back to the water source, which plays a role in unblocking pumping and saving water energy loss.
