Product Details
QLAH-20 G3/4 High pressure one-way throttle valve
Description
Throttle valves are valves that control fluid flow by changing the throttle section or throttle length. Parallel connection of throttle valve and one-way valve can be combined into one-way throttle valve.
Application
Throttle valves and one-way throttle valves are simple flow control valves. In the hydraulic system of quantitative pump, throttle valves and relief valves cooperate to form three throttle speed control systems, namely, intake throttle speed control system, return throttle speed control system and bypass throttle speed control system. Throttle valves have no flow negative feedback function and can not compensate for the speed instability caused by load changes. They are generally only used in situations where the load changes little or the speed stability requirements are not high.
Principle
The shape and structure of the choke valve are not different from that of the globe valve, but the shape of its opening and closing parts is different. The opening and closing parts of throttle valves are mostly conical streamlined, through which the flow and pressure can be regulated by changing the cross-section area of the passage. Throttle valves are used to reduce medium pressure in the case of great pressure drop.
The medium flows very fast between the throttle disc and the valve seat, so that the surface of these parts is damaged quickly, which is called cavitation phenomenon. In order to minimize the effect of cavitation, the valve disc is made of corrosion resistant material (alloy steel) and a streamlined cone with a tip angle of 140-180, which can also make the valve disc have a larger opening height. Throttling under a small gap is generally not recommended.
Function
1. The structure is simple, easy to manufacture and maintain, and the cost is low.
2. The adjustment accuracy is not high and can not be used for adjustment.
3. The sealing surface is easy to erode and can not be used as cutting medium.
