Description

Technical Field

[0001] The utility model belongs to the technical field of detection devices, and in particular relates to a detection device for the deformation force of a temperature controller diaphragm. Background Art

[0002] Thermostat diaphragm refers to a key component used in temperature controllers, usually used to regulate heat transfer between temperature sensors and controllers. Diaphragms are usually made of soft materials, such as silicone rubber or polytetrafluoroethylene. They have good elasticity and high temperature resistance, and can effectively transfer heat at different temperatures, thereby achieving accurate operation of the temperature controller. However, the current detection device for diaphragms can generally only be tested one by one, which is inefficient, time-consuming and labor-intensive.

The detection device of the deformation force of the sudden jump diaphragm of the anti-dry-burning thermostat relates to a pressure detection device, including a substrate, a vacuum gauge, a vacuum pump and a pressure regulating valve. A cylindrical boss is provided on the substrate, and a placement groove for the diaphragm to be tested is provided on the upper surface of the cylindrical boss. The placement groove for the diaphragm to be tested is provided with air holes. Two opposite openings are provided on the circumferential surface of the cylindrical boss. The two openings are interconnected with the air holes in the placement groove for the test diaphragm. One opening on the circumferential surface of the cylindrical boss is connected to a three-way valve through a hose, and the other two valve ports of the three-way valve are connected to the vacuum pump and the vacuum gauge through hoses respectively. The vacuum gauge is fixed on the substrate, and another opening on the circumferential surface of the cylindrical boss is connected to the pressure regulating valve through a hose, and the pressure regulating valve is fixed on the substrate. The utility model can accurately detect the force on the sudden jump diaphragm of the anti-dry-burning thermostat when it is deformed, and the device is very simple and easy to operate. However, the above-mentioned temperature controller diaphragm deformation force detection device cannot detect multiple diaphragms, has low efficiency, and has no solid base for support, which has a great impact on the detection and reduces the accuracy of the detection.
