[0002] The oil pressure protection switch device is an important pressure control device, widely used in multiple industrial fields such as petroleum, chemical industry, automobile, aviation, machine tools and hydraulic machinery. The oil pressure protection switch device adopts high-precision and high-stability pressure sensors and transmission circuits, and then uses dedicated CPU modular signal processing technology to realize the detection, display, alarm and control signal output of the medium pressure signal. When the pressure in the system is higher or lower than the safety pressure, the pressure sensor in the controller will immediately operate to connect or disconnect the contacts in the controller, thereby controlling the operating status of the equipment.

[0003] The oil pressure protection switch device in the existing technology often relies on the setting of sealant for sealing, and materials such as organic silicone have certain properties such as water resistance, high temperature resistance and chemical medium resistance, but their bonding performance may be relatively weak, especially under extreme working conditions, such as high temperature, high pressure or frequent vibration environment. The sealing effect may be affected, resulting in incomplete curing or performance degradation after curing, which reduces the practicality of the switch device. Therefore, we need an oil pressure protection switch device. Utility Model Content
