Metering Pump What Is The Difference Between The Check Valve & Back Pressure Valve Work In The Disch. Line Of Metering Pump?

What is the difference between the check valve & back pressure valve work in the disch. line of metering pump? - metering pump

In a metering pump LMI valves are in the membrane (the bomb) unit. These valves are based on a differential fluid pressure across the valve seat and the operation in its entirety. If you made a face and shook the noise of the pump was listening to the ball.

The valve is the pressure and disadvantages ball retention, but it is a source that keeps the ball at his head. The fluid pressure must increase on the spring force inorder to increase the ball from his seat and flow. Typically mounted on the tube and the procedure of the chemical industry uses the system.

LMI also has an optional diaphragm pressure relief valve that is mounted directly on the pump head. This is the seats of ball valves for differential pressure to help control the ball. It has a small diversion / Beeder, which eliminates the pressure-cons, in order to prime the pump.

The pressure valve has several functions.
1.) Prevents uncontrolled siphon and flow through the chemical feed pump. This is done either achieved through a high speeds through the inlet pipe chemical feed, or because the fluid is in the pipe at a slight vacuum. Spring has opened a size of a much larger pressure that could be generated by a siphon requires.

2.) back pressure valve makes the chemistry of the pump with a higher pressure relief work (caused) by the spring force, the higher pressure also helps to verify the absence of valve spring seat.

3rd assembled) valve on the back of the tube process water is also a check valve. This allows the supply of chemicals and chemical process pump temporarily without water flow switch it off. This allows the rapid exchange of the pump head without interrupting the entire system.
