動切換弁。It is composed of a switching valve part equipped with a valve that switches the fluid flow path, and a pressure comparison part equipped with a diaphragm mechanism that switches the valve, and a set pressure chamber and a signal pressure are defined on both sides by the diaphragm mechanism. communicating with the chamber via a throttle mechanism, and communicating the set royal chamber with the set pressure boat via an orifice that has a larger opening than the throttle mechanism and is opened and closed by the diaphragm mechanism;
The signal royal chamber is connected directly to the signal pressure boat, and the strength of the spring that biases the diaphragm mechanism toward the orifice is controlled against the fluid pressure in the orifice when the set pressure chamber and the signal pressure chamber are at equal pressure. A differential pressure operated switching valve characterized by having a diaphragm mechanism set to a size large enough to close an orifice.
