Description

Technical Field

[0001] The utility model relates to the technical field of thermostatic valve core detection equipment, in particular to a valve handle rotating structure used for thermostatic valve core detection. Background Art

[0002] The valve core is a valve part that enables the valve body to realize the basic functions of direction control, pressure control or flow control. In the production and processing of the valve core, the valve core needs to be tested by a valve core detection device. The detection content includes but is not limited to whether the flow of the valve core meets the standard and the sensitivity, resilience and consistency of the valve core. The detection device for detecting the valve core now includes a detection seat for installing the valve core and a device body for injecting liquid into the detection seat and collecting data. After the valve core is installed on the liquid inlet at one end of the detection seat, the device body respectively delivers cold water and hot water to the liquid inlet of the detection seat, and manually rotates the valve handle of the valve core. The device body collects the temperature change data of the water-liquid mixture in the detection seat under different states of the valve core, thereby detecting whether the flow of the valve core meets the standard and the sensitivity, resilience and consistency of the valve core.
