The self-closing valve solves the problem of low sealing performance of the existing pipeline gas self-closing valve. The precise buried pipeline gas self-closing valve comprises a valve body and a pressing sleeve arranged in the valve body, wherein a through hole which can be tightly pressed by the pressing sleeve to form a seal is formed in the valve body, a valve body pipeline for the opening is also arranged in the valve body, a sealing device is fixed on the end wall of the valve body pipeline, and a sealing groove for sealing and embedding the end wall of the pressing sleeve is arranged at the position corresponding to the sealing device. The utility model has the advantages of improving the sealing performance and preventing leakage.
Description
Technical Field
The utility model belongs to the technical field of valves, and relates to a gas self-closing valve, in particular to a precise buried pipeline gas self-closing valve.
Background
The self-closing valve is automatically closed when the air is stopped or the air pressure is reduced to a certain value, and a pressure sleeve in the valve body props against the corresponding position of the inner wall of the valve body. Because the internal structure of the existing self-closing valve is simple, after the automatic closing state is formed, the sealing performance between the pressing sleeve and the valve body is deficient, so that the leakage condition occurs, and the use is influenced.
Disclosure of Invention
The utility model aims to solve the problems in the prior art and provides a high-tightness precise buried pipeline gas self-closing valve.
The aim of the utility model can be achieved by the following technical scheme: the utility model provides a precision buried pipeline gas self-closing valve, includes the valve body and sets up the pressure cover in the valve body, its characterized in that, the valve body in have can be by the pressure cover pressure form sealed opening, still have the valve body pipeline that supplies the opening to set up in the valve body, be fixed with sealing device on the valve body pipeline end wall, the pressure cover end wall position department corresponding to sealing device set up and supply its sealed embedded seal groove;
The sealing device comprises a sealing main body and a sealing tightening part which is bent outwards and extends from the sealing main body, a space groove which can change the space size is formed between the sealing tightening part and the sealing main body, and a sealing salient point which is in sealing contact with a notch of the sealing groove is formed on the sealing tightening part.
In the precise buried pipeline gas self-closing valve, the sealing device is made of rubber materials.
In the precise buried pipeline gas self-closing valve, the sealing main body is provided with the outward-expanding sealing support part.
Compared with the prior art, the precise buried pipeline gas self-closing valve has the advantages of improving sealing performance and preventing leakage.

Figure 2 is a schematic illustration of the process of the seal device accessing the seal groove.
In the figure, 1, a valve body; 2. pressing the sleeve; 3. a through port; 4. a valve body pipe; 5. sealing grooves; 6. a sealing body; 7. sealing the tightening part; 8. a space groove; 9. sealing the salient points; 10. and a seal support.
Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
As shown in fig. 1 and 2, the precise buried pipeline gas self-closing valve comprises a valve body 1 and a pressing sleeve 2 arranged in the valve body 1, wherein a through hole 3 capable of being pressed by the pressing sleeve 2 to form a seal is formed in the valve body 1, a valve body pipeline 4 for the through hole 3 to be formed in the valve body 1 is further arranged in the valve body, a sealing device is fixed on the end wall of the valve body pipeline 4, a sealing groove 5 for sealing and embedding the sealing device is formed at the position of the end wall of the pressing sleeve 2 corresponding to the sealing device, the sealing device comprises a sealing main body 6 and a sealing tightening part 7 which is bent and extended outwards by the sealing main body 6, a space groove 8 capable of changing the space size is formed between the sealing tightening part 7 and the sealing main body 6, the sealing tightening part 7 is provided with a sealing salient point 9 which is in sealing contact with a notch of the sealing groove 5, when the pressing sleeve 2 is pressed against the end wall of the valve body pipeline 4, the sealing groove 5 is accommodated in the sealing groove 5, in the sealing device takes the sealing salient point 9 as a boundary point, and the sealing device at the front half part of the sealing salient point can smoothly enter the sealing groove 5, when the sealing salient point 9 is contacted with the sealing salient point 9, the sealing salient point is pressed against the notch, and the sealing salient point 9 is pressed inwards by the sealing sleeve 2, and the sealing salient point is kept against the sealing groove 8, and the sealing groove is kept in the sealing groove 5, and the sealing groove is formed, and the sealing groove is sealed, and the sealing groove is high in efficiency, and has high sealing efficiency, and the sealing efficiency.
Preferably, the sealing means is made of a rubber material.
Further, the sealing main body 6 is provided with an outward-expanding sealing supporting part 10, so that the volume is increased, and the supporting force is further improved.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
Although terms such as the valve body 1, the pressure jacket 2, the through port 3, the valve body pipe 4, the seal groove 5, the seal body 6, the seal tightening portion 7, the inter-groove 8, the seal bump 9, the seal support portion 10, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely for convenience in describing and explaining the nature of the utility model; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present utility model.
