Description

Technical Field

[0001] The invention relates to the technical field of pressure resistance testing, in particular to a pressure resistance performance testing device for a digital throttle valve. Background Art

[0002] A throttle valve is a valve that controls the flow of fluid by changing the throttle section or throttle length. A throttle valve and a check valve can be combined into a one-way throttle valve by connecting them in parallel. The throttle valve and the one-way throttle valve are simple flow control valves. In the hydraulic system of a quantitative pump, the throttle valve and the relief valve can be combined to form three throttling speed control systems, namely the oil inlet throttling speed control system, the oil return throttling speed control system and the bypass throttling speed control system. The throttle valve has no flow negative feedback function and cannot compensate for the speed instability caused by load changes. It is generally only used in situations where the load changes are not large or the speed stability requirements are not high. The throttle valve must be tested for its pressure resistance performance.

[0003] In the existing throttle valve production process, the spring is mainly pressed by a pressure rebound force tester mechanism, and the pressure resistance performance of the throttle valve is tested by whether the elastic force of the spring meets the standard. If the elastic force of the spring meets the standard, it means that the pressure resistance performance of the throttle valve is qualified, otherwise it does not meet the standard. When the traditional testing mechanism tests the throttle valve, it is relatively difficult to tighten the throttle valve well due to the irregular shape of the throttle valve, and the data value obtained by the testing mechanism is not accurate enough.
