Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and relates to an anti-freezing valve, in particular to a novel anti-freezing valve. Background Technique

[0002] At present, the valve body of the anti-freezing valve is only connected to the top and bottom components (locking cap and drain seat) by threads, and a sealing ring is placed between the valve body and the corresponding components before connection. The main purpose is to play a sealing role. However, this sealing structure is prone to aging and failure after a long time, and usually the top and bottom components are not disassembled, and the sealing structure is not easy to replace, which still affects the sealing performance. Summary of the Invention

[0003] The purpose of the utility model is to provide a novel anti-freezing valve with high sealing performance for the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A novel anti-freezing valve includes a valve body. It is characterized in that a cylindrical spring one, a thermal sensitive element, a copper core and a cylindrical spring two are sequentially arranged in the valve body from top to bottom. A fluid pipeline with an inlet and an outlet at both ends is formed on the valve body. A through hole communicating with the fluid pipeline is opened at a position corresponding to the copper core on the valve body. A locking cap is threadedly connected to the top of the valve body, and a drain seat with a drain port is threadedly connected to the bottom of the valve body. Both between the valve body and the locking cap and between the valve body and the drain seat are sealed and fixed by anaerobic glue.

[0005] In the above novel anti-freezing valve, a rubber gasket is provided between the bottom of the copper core and the drain seat.

[0006] In the above novel anti-freezing valve, an O-ring is provided between the valve body and the locking cap.

[0007] In the above novel anti-freezing valve, a guide pad is installed on the thermal sensitive element.

[0008] In the above novel anti-freezing valve, a vacuum valve assembly is installed on the locking cap.

[0009] Compared with the prior art, the novel anti-freezing valve has the advantages of reliable induction and strong sealing performance. Brief Description of the Drawings

Specific Embodiment

[0013] The following are specific embodiments of the present invention and, in conjunction with the accompanying drawings, further describe the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0014] As Figure 1 、 Figure 2 shown, the novel anti-freeze valve includes a valve body 1. Inside the valve body 1, there are successively arranged from top to bottom a first cylindrical spring 2, a thermal element 3, a copper core 4, and a second cylindrical spring 5. On the valve body 1, a fluid pipeline 6 with an inlet and an outlet at both ends is formed. At a position corresponding to the copper core 4 on the valve body 1, a through port 7 communicating with the fluid pipeline 6 is opened. The thermal element 3 is set slightly above, in the upper layer of the fluid, so that the induction stability is higher and more reliable. The top of the valve body 1 is threadedly connected with a locking cap 8, and its bottom is threadedly connected with a drain seat 9 with a drain port. Both between the valve body 1 and the locking cap 8 and between the valve body 1 and the drain seat 9 are sealed and fixed by an anaerobic adhesive 10. After threaded connection, the anaerobic adhesive 10 is injected for fixation to achieve a glue-sealed structure and improve the sealing performance.

[0015] Preferably, a rubber gasket 11 is provided between the bottom of the copper core 4 and the drain seat 9.

[0016] Further elaborating, an O-ring 12 is provided between the valve body 1 and the locking cap 8, and the O-ring 12 is also assembled to achieve double-layer sealing.

[0017] Preferably, a guide pad 13 is installed on the thermal element 3.

[0018] Preferably, a vacuum valve assembly 14 is installed on the locking cap 8.

[0019] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0020] Although terms such as valve body 1, first cylindrical spring 2, thermal element 3, copper core 4, second cylindrical spring 5, fluid pipeline 6, through port 7, locking cap 8, drain seat 9, anaerobic adhesive 10, rubber gasket 11, O-ring 12, guide pad 13, vacuum valve assembly 14, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
