Stainless steel rotary diaphragm valve used in Chemical industry

Short Description:

Rotary valves are also called valves. Valves are usually divided into two categories: linear and rotary. The linear-stroke valve allows or cuts off the flow of material through a linearly moving part such as a gate. The straight-stroke valve includes globe valve, gate valve, diaphragm valve and so on. The rotary valve allows or cuts off the flow through a rotating part. A rotary valve whose rotating part can rotate 90 degrees is called a 1/4 rotary valve. Sometimes the classification of 1/4 rotary valves can be extended to rotary valves with a rotation angle of less than 270 degrees. It can be seen from the definition that a rotary valve is a rotary valve that changes the valve from an open position to a closed position by rotating a rotating part such as a rotating baffle by 90 degrees.

Description

The working principle of diaphragm valve is that during the compression and power stroke of the engine, the gas pressure in the combustion chamber is greater than that in the crankcase. The gas in the combustion chamber enters into the crankcase through the piston ring. In addition, the oil splashes in the crankcase. Under the action of the crankcase ventilation system, it enters the cover inlet. If the engine runs under full load condition, the mixed air flows into the full load chamber and passes through the maze When the oil level reaches 15mm, that is, the pressure reaches 1.2mbar, Under the action of oil gravity, the diaphragm valve is opened to drain the oil; when the oil level is less than 15mm, the diaphragm valve is closed, and the separated crankcase gas flows into the air filter connecting pipe through the full load pipe and enters the engine combustion chamber for combustion; similarly, the engine operates under partial load, and the oil in the mixture is released by using the partial load diaphragm valve.
