Description

Technical Field

[0001] This application relates to the technical field of valves, and particularly to an ultra-thin valve body. Background Art

[0002] The utility model patent with the publication number CN22899905U discloses a gas fine-tuning ignition valve, which includes an ignition valve body. A valve rod is rotatably connected in the middle of the ignition valve body. An air vent hole is opened in the middle of the valve rod. A fine-tuning rod of the ignition valve is threadedly connected in the middle of the valve rod. A valve rod end face nut is fixedly connected to the middle of the top of the valve rod. A positioning connection block is fixedly connected to the outer wall of the valve rod. A handle locking nut is fixedly connected to the end of the fine-tuning rod of the ignition valve. The outer wall of the ignition valve body is respectively communicated with an air inlet end, a handle control end, an air outlet end and a main air valve connection end. The handle control end and the air outlet end are located on the same axis. The fine-tuning rod of the ignition valve, the valve rod and the handle control end are arranged in sequence from the inside to the outside.

[0003] The above patent document installs the fine-tuning rod of the ignition valve by opening an air vent hole in the valve rod. Drilling holes in the middle of the valve rod will reduce its strength. In order to ensure the strength of the valve rod, the diameter of the valve rod with the above structure is usually designed to be larger, and the corresponding valve body diameter also becomes larger, resulting in a larger valve body volume.

[0027] Refer to Figures 1-5 , the ultra-thin valve body described in this embodiment includes:

[0028] A valve body 1, on which a valve cavity 11 is provided. An air outlet 2 communicating with the valve cavity 11 and an air inlet 4 communicating with the intake passage 3 and the valve cavity 11 are provided on the valve body 1;

[0029] A fine-tuning passage 5 is further provided on the valve body 1. One end of the fine-tuning passage 5 communicates with the intake passage 3, and the other end thereof extends to communicate with the valve cavity 11 to form a fine-tuning hole 6;

[0030] A fine-tuning member 7 is installed on the valve body 1, and the fine-tuning member 7 can be moved into or out of the fine-tuning passage 5 under the action of an external force;

[0031] A valve core 8 is rotatably arranged in the valve cavity 11;

[0032] The valve stem 9 is rotatably arranged on the valve body 1. One end of the valve stem 9 is connected to the valve core 8, and the other end of the valve stem 9 extends outside the valve cavity 11. Under the action of an external force, the valve stem 9 can drive the valve core 8 to rotate so that the valve core 8 selects to conduct the fine adjustment hole 6 or the air inlet 4 with the valve cavity 11.

[0033] Refer to the attached Figures 1-2 As shown, a through hole is provided on the valve core 8. When the valve stem 9 is pressed down and rotated under force, the valve stem 9 will drive the valve core 8 to rotate synchronously so that the through hole on the valve core 8 communicates with the fine adjustment hole 6 or the air inlet 4.

[0034] When the valve core 8 rotates until the through hole communicates with the air inlet 4, after the gas flows into the valve cavity 11 through the air inlet passage 3 and the air inlet 4, it then flows out through the air outlet passage, and the fine adjustment passage 5 does not affect the opening and closing of the gas path.

[0035] When the valve core 8 rotates until the through hole communicates with the fine adjustment hole 6, the gas flows into the valve cavity 11 through the air inlet passage 3, the fine adjustment passage 5 and the fine adjustment hole 6, and then flows out through the air outlet passage; when the valve core 8 rotates until the through hole communicates with the fine adjustment hole 6, an external force adjusts the fine adjustment member 7, and the size of the gas flow rate is adjusted by adjusting the length of the fine adjustment member 7 extending into the fine adjustment passage 5, thereby realizing the fine adjustment of the gas.

[0036] In this embodiment, the fine adjustment member 7 is a threaded member. A threaded hole 10 communicating with the fine adjustment passage 5 is provided on the valve body 1, and the fine adjustment member 7 is screwed at the threaded hole 10. Rotating the fine adjustment member 7 changes the length of its extension into the fine adjustment passage 5.

[0037] Specifically, the threaded hole 10 is a countersunk hole, and the countersunk hole includes a small hole section 101 and a large hole section 102. Internal threads are provided on the inner wall of the small hole section 101, and a limiting step 71 is provided on the fine adjustment member 7. As shown in the attached drawing, when the fine adjustment member 7 is screwed into the small hole section 101 and when the fine adjustment member 7 is screwed into the small hole section 101 until the limiting step 71 abuts against the small hole section 101, the gas can still flow into the valve cavity 11 through the fine adjustment passage 5 to prevent the fine adjustment member 7 from blocking the fine adjustment passage 5.

[0038] Based on the above, a sealing ring 12 is further included. The sealing ring 12 is sleeved on the fine adjustment member 7 and is in sealing contact with the threaded hole 10 to improve the sealing performance.

[0039] Preferably, the threaded hole 10 is arranged at the upper end of the valve body 1 for convenient rotation.

[0040] Certainly, the present utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations and substitutions are all included within the scope defined by the claims of this application.
