What is Marine Foot Valve?

Marine Foot valve is a kind of energy-saving valve, generally installed in the pump underwater suction pipe at the bottom. Restriction of the pump pipe liquid back to the water source, playing the function of only in and out. The valve cover has a lot of water inlet products and reinforcement, played not easy to block, mainly used in pumping pipeline: waterway and the role of support. There are only single valve, double valve, multi-valve type. There are flange connection and threaded connection.

Overview

Working Principle

Water from the valve cover into the valve body. Under the action of fluid pressure, the valve flap to open the water, when the signal stops after the pressure in the outlet pipe will valve flap quickly closed, the liquid will not fall back to the water source, play a role that is unimpeded pumping and save the role of the loss of water energy.

Main Structure

The main structure of marine foot valve includes valve body, valve cover, valve flap, spring and other parts. Valve body is generally spherical or conical, there is a water hole inside, used to make the water flow through. Valve cover installed in the valve body, through the bolts and the valve body, the valve cover above the inlet and outlet, respectively, with the inlet pipe and outlet pipe connected to the water pump. Valve is located inside the valve body, connected to the valve body through the spring, when the pump works, the water flow through the valve body, the valve valve in the role of water pressure is up, so that the water flow through; when the pump stops working, the valve in the role of the spring is automatically closed, to prevent the backflow of water.
