Introduction And Characteristics Of Throttle Valve 

The throttle valve is a valve that controls the flow of fluid by changing the throttle section or throttle length. Connect the throttle valve and the one-way valve in parallel to form a one-way throttle valve. The throttle valve and the one-way throttle valve are simple flow control valves. In the hydraulic system of a fixed pump, the throttle valve and the overflow valve can be combined to form three types of throttle speed control systems, that is, the throttle speed control system of the oil inlet. System, oil return line throttling speed control system and bypass throttling speed control system. The throttle valve has no flow negative feedback function, and cannot compensate for the unstable speed caused by the load change. It is generally only used for occasions where the load change is not large or the speed stability is not high.

Features:

1. The structure is relatively simple, easy to manufacture and maintain, and low cost.

2. The adjustment accuracy is not high and cannot be used for adjustment.

3. The sealing surface is easily eroded and cannot be used as a cutting medium.

4. Poor airtightness.
