Technical Field

[0001] The utility model belongs to the technical field of valves, and relates to an antifreeze valve, in particular to a new type of water-drop anti-wall-hanging antifreeze valve. Background Art

[0002] The antifreeze valve is mainly used to protect outdoor heating equipment from freezing when it stops operating in a low-temperature freezing environment, and to prevent the heating equipment pipeline from cracking.

[0003] At present, when water drops at the drain nozzle of the antifreeze valve, especially when dripping slowly, the water drops will hang on the wall surface of the drain nozzle. Due to the influence of the low-temperature environment, ice is likely to form on the drain nozzle, affecting the use. Summary of the Invention

[0004] The purpose of the utility model is to provide a new type of water-drop anti-wall-hanging antifreeze valve to solve the above problems existing in the prior art.

The antifreeze assembly includes a housing and a pressing spring, a flow guiding gasket, a temperature sensing element, a push rod, an opening spring and an exhaust nozzle which are sequentially arranged in the housing. The valve body has a threaded connection end threadedly connected to the housing. The two ends of the pressing spring respectively abut against the flow guiding gasket and the inner wall of the housing. The flow guiding gasket allows the temperature sensing element to pass through, and the temperature sensing element abuts against the push rod. The two ends of the opening spring respectively abut against the push rod and the inner wall of the housing. A sealing member for sealing the exhaust nozzle is installed at the bottom of the push rod. The lower end of the exhaust nozzle is threadedly connected in the housing, and a water-drip prevention table extends outward from the bottom of the exhaust nozzle. The lower end of the water-drip prevention table has two oppositely formed pointed nozzle parts, and a pointed opening is formed between the two pointed nozzle parts. The distance between the two sides of the pointed nozzle part decreases sequentially from top to bottom.

[0006] In the above-mentioned new type of water-drop anti-wall-hanging antifreeze valve, the valve body has a mounting seat for installing the vacuum valve assembly.

[0007] In the above-mentioned new type of water-drop anti-wall-hanging antifreeze valve, the vacuum valve assembly is composed of a vacuum valve piston, a sealing gasket and a vacuum valve air inlet plug. The sealing gasket is installed between the vacuum valve air inlet plug and the mounting seat.

[0008] Compared with the prior art, the new type of water-drop anti-wall-hanging antifreeze valve has the advantages of preventing water drops from hanging on the wall and improving the use effect. Brief Description of the Drawings

Specific implementation manner

[0013] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0014] As Figure 1 、 Figure 2 、 Figure 3 shown, the new water droplet anti-wall-hanging and anti-freezing valve includes a valve body 1, on which a vacuum valve assembly and an anti-freezing assembly are oppositely arranged. The anti-freezing assembly includes an outer shell 2 and a downward pressure spring 3, a flow guiding gasket 4, a temperature sensing element 5, an ejector rod 6, an opening spring 7 and an exhaust nozzle 8 sequentially arranged in the outer shell 2. The valve body 1 has a threaded connection end 9 threadedly connected to the outer shell 2. Both ends of the downward pressure spring 3 respectively abut against the flow guiding gasket 4 and the inner wall of the outer shell 2. The flow guiding gasket 4 allows the temperature sensing element 5 to pass through, and the temperature sensing element 5 abuts against the ejector rod 6. Both ends of the opening spring 7 respectively abut against the ejector rod 6 and the inner wall of the outer shell 2. The bottom of the ejector rod 6 is equipped with a seal 10 for sealing the exhaust nozzle 8. The lower end of the exhaust nozzle 8 is threadedly connected in the outer shell 2, and the bottom of the exhaust nozzle 8 extends outward with an anti-drip platform 11. The lower end of the anti-drip platform 11 has two oppositely formed pointed nozzle parts 12. A pointed opening 13 is formed between the two pointed nozzle parts 12. The distance between the two sides of the pointed nozzle part 12 gradually decreases from top to bottom. Through the structural characteristics of the pointed nozzle part 12, the contact area when the water droplet drips is reduced, the dripping speed is increased, and the water droplet cannot hang, and thus the ice formation phenomenon will not occur.

[0015] Preferably, the valve body 1 has a mounting seat 14 for installing the vacuum valve assembly.

[0016] Preferably, the vacuum valve assembly is composed of a vacuum valve piston 15, a sealing gasket 16 and a vacuum valve intake plug 17. The sealing gasket 16 is installed between the vacuum valve intake plug 17 and the mounting seat 14.

[0017] When the water temperature in the pipeline is higher than the corresponding temperature (about 4°C), the downward pressure spring 3 acts on the diversion gasket 4, and under the action of the temperature sensing element, a downward force is applied through the seal 10 at the front end of the push rod 6 to close the drain nozzle; when the water temperature is lower than the corresponding temperature (about 3°C), the temperature sensing element 5 contracts, and the opening spring 7 pushes the push rod 6 upward and acts on the temperature sensing element 5 to open the drain nozzle to prevent the pipeline from freezing; at the same time, the vacuum valve piston 15 moves downward to open and inhale air to drain the liquid in the pipeline; when water is injected into the valve body 1 (the two ends of the valve body 1 are the water inlet and the outlet respectively), and the water temperature rises above the corresponding temperature (about 4°C), the vacuum valve piston 15 placed at the top can quickly drain the air in the pipeline to prevent air from not filling the water when the valve body 1 is filled with water.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art 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.

[0019] Although terms such as valve body 1, outer shell 2, downward pressure spring 3, diversion gasket 4, temperature sensing element 5, push rod 6, opening spring 7, exhaust nozzle 8, threaded connection end 9, seal 10, drip-proof platform 11, pointed nozzle part 12, pointed opening 13, mounting seat 14, vacuum valve piston 15, sealing gasket 16, vacuum valve air inlet plug 17, etc. are used more frequently in this article, the possibility of using other terms is not excluded. Using these terms is only for more conveniently describing and explaining the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
