Temperature sensitive drum for temperature control valve

Abstract

The invention relates to a temperature sensitive drum for a temperature control valve, comprising a base and a copper tube arranged on the base. The temperature sensitive drum is characterized in that the base is provided with a connecting part for connecting the copper tube; the outer surface of the connecting part is provided with threads; the end part of the connecting part is connected with the end part of the copper tube; and the copper tube and the base are cast by one time and are integrally molded. In the temperature sensitive drum, the copper tube is integrally molded with the base and the connecting part, so that the connecting stability of the copper tube and the base is increased, simultaneously the complex operation process on the prior art is avoided, and the pollution of the acid cleaning on the environment is avoided. The temperature sensitive drum has the advantages of simple operation, stable structure and long service life and the like, improves the production efficiency of enterprises and has promotion and use values.

Description

technical field [0001] The invention relates to the field of temperature controllers, in particular to a temperature-sensing cylinder for a temperature control valve. Background technique [0002] The temperature control valve, referred to as the temperature control valve, is a typical application of the flow control valve in the field of temperature control. Control the outlet temperature of the equipment. When the load changes, the flow is adjusted by changing the opening degree of the valve to eliminate the influence caused by the load fluctuation and restore the temperature to the set value. The core component of the temperature control valve is the temperature-sensing cylinder, also known as the temperature-sensing package, which can sense changes in the ambient temperature and produce volume changes, which drive the displacement of the regulating valve spool. The temperature-sensing package of the temperature control valve is generally assembled into a whole with the...

Problems solved by technology

[0003]The existing temperature sensing cylinder includes a base, a welding ring and a copper tube arranged on the base, and the end of the copper tube is connected to the together; then carry out surface acid treatment, and then remove the grease and dirt on the surface and other operations. The process is complex, the production efficiency is low, and the cost is high. Since the copper tube and the base are welded, it is easy to cause poor welding , resulting in damage to the temperature-sensing cylinder, and after pickling operation, the acid solution will cause environmental pollution
