Abstract

The utility model provides a temperature control valve head with a lock catch, and belongs to the technical field of constant temperature control valves. The temperature sensing expansion assembly of the temperature control valve head solves the problem that the temperature sensing expansion assembly of an existing temperature control valve head shakes and makes abnormal sound in the using process, and use is affected. The temperature control valve head with the lock catch comprises an outer shell, a top cap, a top shell, a bottom shell and a temperature sensing expansion assembly arranged in the top shell, a plurality of enlarged temperature sensing openings are formed in the outer shell, metal nets are arranged at the enlarged temperature sensing openings, and a plurality of long through grooves communicated with the enlarged temperature sensing openings are formed in the top shell in the circumferential direction of the top shell. A supporting gasket used for fixing the temperature sensing expansion assembly is installed in the shell in a positioning mode, a plurality of gasket clamping protrusions clamped into the long through groove are arranged on the circumferential wall of the supporting gasket, and the top walls of the gasket clamping protrusions are attached to the top wall of the long through groove in a supporting mode. The temperature sensing expansion assembly has the advantages of being good in positioning effect and capable of preventing abnormal sound.

Description

Technical Field

[0001] This utility model belongs to the field of thermostatic control valve technology, and relates to a temperature control valve head, particularly a temperature control valve head with a locking mechanism. Background Technology

[0002] Currently, the temperature sensing element inside the temperature control valve head, namely the temperature-sensing expansion component, lacks support and positioning during use, causing it to shake and produce abnormal noises, thus affecting its use. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a locking temperature control valve head that prevents abnormal noise.

[0004] The objective of this utility model can be achieved through the following technical solution: A temperature control valve head with a locking mechanism, comprising a housing, a top cap, a top shell, a bottom shell, and a temperature sensing expansion component disposed within the top shell, characterized in that the housing has multiple enlarged temperature sensing ports, each enlarged temperature sensing port is provided with a metal mesh, the top shell has multiple elongated slots communicating with the enlarged temperature sensing ports around its circumference, a support pad for fixing the temperature sensing expansion component is positioned and installed inside the housing, the support pad has multiple pad protrusions on its peripheral wall that snap into the elongated slots, and the top wall of the pad protrusions fits and supports the top wall of the elongated slot.

[0005] In the aforementioned type of temperature control valve head with a locking mechanism, the enlarged temperature sensing port has an elongated slot structure.

[0006] Compared with existing technologies, this locking temperature control valve head has the advantages of better positioning of the temperature-sensing expansion component and prevention of abnormal noise. Attached Figure Description

Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 , Figure 3 As shown, this locking temperature control valve head includes a housing 1, a top cap 2, a top shell 3, a bottom shell 4, and a temperature sensing expansion component 5 disposed inside the top shell 3. The housing 1 has multiple enlarged temperature sensing ports 6, and a metal mesh 7 is provided at each enlarged temperature sensing port 6. The top shell 3 has multiple elongated slots 8 around its circumference that communicate with the enlarged temperature sensing ports 6. A support pad 9 for fixing the temperature sensing expansion component 5 is positioned and installed inside the housing 1. The support pad 9 has multiple pad protrusions 10 on its peripheral wall that snap into the elongated slots 8. The top wall of the pad protrusions 10 fits against the top wall of the elongated slot 8 for support. By fastening the pad protrusions 10, the temperature sensing expansion component 5 is limited and fixed internally, thus solving the problem of shaking and abnormal noise of the temperature sensing expansion component 5.

[0013] To elaborate further, the temperature sensing port 6 is enlarged into an elongated groove structure, the original traditional temperature sensing port is enlarged, and a metal mesh design is adopted.

[0014] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0015] Although this document frequently uses terms such as outer shell 1, top cap 2, top shell 3, bottom shell 4, temperature sensing expansion component 5, enlarged temperature sensing port 6, metal mesh 7, long through groove 8, support pad 9, and pad retaining protrusion 10, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
