Abstract

The invention discloses a compact high-reliability and quick-response bellows temperature-sensing wax temperature control valve core, relates to the field of temperature control valve cores, including a wax storage tank, a temperature-sensing material, a guide rail, a bellows and a push rod, wherein the bellows The top opening is welded to the opening of the wax storage tank. The bellows are located inside the wax storage tank to form an integrated welded structure. The temperature-sensitive material is filled in the integrated welded structure formed by the bellows and the wax storage tank. The push rod is located in the hollow space inside the bellows. The cavity is welded together with the bottom seal of the bellows, and the guide rail is installed around the bellows. The invention has the advantages of compact structure, fast response speed, safety and reliability, and no risk of bellows bursting.

Description

technical field [0001] The invention relates to the field of temperature-controlled valve cores, in particular to a compact, highly reliable and fast-response bellows temperature-sensing wax temperature-controlled valve core. Background technique [0002] Hydraulic systems, lubrication systems, liquid cooling systems and other devices usually require control of the oil temperature of their working fluids, especially hydraulic systems that require high temperature control accuracy during operation, such as servo systems, proportional systems, hydraulic components Test benches and large-scale hydraulic equipment in continuous operation, etc. [0003] At present, the common temperature control methods in my country are the cooling control of electrical measurement and electronic control and mechanical combination matching, and the cooling control of mechanical structure driven by temperature-sensitive materials. The former system is complex in composition, has many fault point...
