Breakthrough temperature control release switch

Abstract

The invention discloses a breakthrough temperature control release switch. The breakthrough temperature control release switch comprises a valve body, a valve deck assembly, a magnetic control actionassembly and a temperature control assembly. The valve body is provided with a water inlet, a water outlet and an upper end opening, an elastic membrane is arranged at the upper end opening in a sealed manner, the elastic membrane is provided with a middle hole and a side water outlet, and the water inlet communicates with the water outlet through the middle hole and the side water outlet. The valve deck assembly is connected to the upper end opening of the valve body. The magnetic control action assembly comprises a passive magnetic ring assembly, an active magnetic ring assembly and a compression spring, all of which are coaxially arranged, the passive magnetic ring assembly is used for blocking the middle hole, the active magnetic ring assembly is arranged on the peripheral side of thepassive magnetic ring assembly in a sleeving manner, and the compression spring is compressed between the valve deck assembly and the active magnetic ring assembly. The temperature control assembly comprises fusible alloy, a temperature control piece and a temperature control base, the temperature control base is connected with the valve deck assembly, and the temperature control piece is connected with the temperature control base through the fusible alloy and connected with the active magnetic ring assembly. By means of the breakthrough temperature control release switch, the temperature sensing effect and the working reliability of the release switch are improved, and the application range of the release switch is expanded.

Description

technical field [0001] The present application relates to the technical field of control valves, in particular to a breakthrough temperature control release switch. Background technique [0002] The temperature control switch is mainly used in water, gas, oil and other medium pipelines. It needs to automatically release the medium in the pipeline according to the change of ambient temperature. The principle is to control the circulation of the medium in the pipeline by sensing the change of ambient temperature. , Applied in the cooling, spraying and spraying of the water spraying system. [0003] In the prior art, the memory alloy is used as the temperature sensing element in the cooling and spraying system, but the material of the memory alloy will be deformed due to the aging effect, and the temperature sensing effect will be deteriorated, and timely cooling, spraying and spraying cannot be achieved. Operation, when the memory alloy material has a large deformation error,...

Problems solved by technology

[0003] In the prior art, the memory alloy is used as the temperature sensing element in the cooling and spraying system, but the material of the memory alloy will be deformed due to the aging effect, and the temperature sensing effect will be deteriorated, and timely cooling, spraying and spraying cannot be achieved. Operation, when the deformation error of the memory alloy material is large, it is not suitable to use, and it is not easy to be replaced

In addition, the temperature control switch in the prior art also has the disadvantages of low reliability and small application range
