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
What the present invention relates to is the temperature controller field, and what be specifically related to is that a kind of heat-operated valve is used temperature sensing tube.
Background technique
It is the typical application of flow control valve in domain of control temperature that heat-operated valve is called for short thermostat valve; Its basic principle: through control heat exchanger, air-conditioning unit or other with heat, cool equipment, hot (cold) matchmaker inlet flow rate once, to reach the control apparatus outlet temperature.When load changes, regulate flow through changing valve opening degree, to eliminate the influence that fluctuation of load causes, make temperature return to setting value.And the core component on the thermostat valve is a temperature sensing tube, and it claims bulb again, can respond to the variation of ambient temperature and produces change in volume, drives regulation valve core and produces displacement.The bulb of thermostat valve and valve body generally are assembled into an integral body, and bulb itself promptly is on-the-spot indoor temperature transmitter.
Existing temperature sensing tube comprises base, is arranged on weldering circle and copper pipe on the base, and this copper pipe end links together through the weldering circle and through after the high-temperature soldering; Carry out surface acid then and handle, remove a plurality of operating procedures such as grease and the dirty part of stolen goods on surface again, its complex process, manufacturing efficiency is low, cost is high because copper pipe and
BaseBe welded structure, the phenomenon that it is easy to generate failure welding causes the damage of temperature sensing tube, and through the pickling operation, its acid solution causes environmental pollution.
Summary of the invention
To the deficiency that exists on the existing technology; The present invention seeks to be to provide a kind of technology simple, easy to make, manufacturing efficiency height and constitutionally stable heat-operated valve are used temperature sensing tube; Improve the manufacturing efficiency of enterprise, avoided failure welding or pickling partly to cause environmental pollution
To achieve these goals, the present invention realizes through following technological scheme:
Heat-operated valve is used temperature sensing tube, comprises base and is arranged on the copper pipe on the base, it is characterized in that; On said base, be provided with the joint that connects copper pipe; The outer surface of said joint is provided with screw thread, and said joint end connects said copper pipe end, and said copper pipe and base are that disposal pouring is one-body molded; Increase the steadiness that copper pipe is connected with base, avoid the influence of operation and the acid solution of later stage pickling environment.
The present invention is one-body molded with copper pipe and base and joint, has increased copper pipe and base connection stability, simultaneously; Avoid the complex operations technology on the existing technology, avoid the pollution of pickling to environment, it has simple to operate; Structural stability; Advantages such as long service life have improved the manufacturing efficiency of enterprise, are worth of widely use.
Description of drawings
Specify the present invention below in conjunction with accompanying drawing and embodiment;
Fig. 1 is a structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with embodiment, further set forth the present invention.
Embodiment:
Referring to Fig. 1; A kind of convenient for production, stable, the simple heat-operated valve of technology that present embodiment provides are used temperature sensing tube, comprise base 1 and copper pipe 3, and said base 1 is provided with the joint 2 that connects copper pipe 3; The outer surface of said joint 2 is provided with screw thread, is convenient to the installation of temperature sensing tube through screw thread.
In the present embodiment; Connect the end of copper pipe in the end of joint 2, copper pipe 3 is that disposal pouring is one-body molded with base 1, makes to connect between it to stablize; Increase copper pipe 3 and the steadiness that base 1 is connected, avoid the influence of operation and the acid solution of later stage pickling environment.
The copper product that above-mentioned copper pipe and base all adopt, and through the moulding of mould disposal pouring, its technology is simple, has improved manufacturing efficiency greatly.
The present invention is one-body molded with base 1 and joint 2 with copper pipe 3, has increased copper pipe 3 and base 1 connection stability, simultaneously; Avoid the complex operations technology on the existing technology, avoid the pollution of pickling to environment, it has simple to operate; Structural stability; Advantages such as long service life have improved the manufacturing efficiency of enterprise, are worth of widely use.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The scope of the claimed invention by the appended claims and their equivalents defined
.
