Abstract
The utility model discloses a kind of self-closing device of carbon dioxide steel cylinder valve, the spring swivel nut that its position, air outlet being included in valve sets gradually successively from inside to outside, spring, spool, one-way valve valve body, an O shape circle and the 2nd O shape circle, described spring is positioned at described spring swivel nut, and described spring promotes described spool makes the 2nd O shape circle on described spool contact with the conical surface of described one-way valve valve body.The self-closing device of carbon dioxide steel cylinder valve of the present utility model, sealing is tight, can realize automatic closedown, easy to operate.
Description
Technical field
The utility model relates to valve applications technical field, particularly a kind of self-closing device of carbon dioxide steel cylinder valve.
Background technique
The air outlet of carbon dioxide steel cylinder valve traditional is at present open type, relies on switch valve realize out and close, and there is the problems such as poorly sealed, operation is inconvenient.
Model utility content
In order to solve the problems of the technologies described above, the utility model proposes a kind of self-closing device of carbon dioxide steel cylinder valve, sealing is tight, can realize automatic closedown, easy to operate.
The technical solution of the utility model is achieved in that
A kind of self-closing device of carbon dioxide steel cylinder valve, the spring swivel nut that its position, air outlet being included in valve sets gradually successively from inside to outside, spring, spool, one-way valve valve body, an O shape circle and the 2nd O shape circle, described spring is positioned at described spring swivel nut, and described spring promotes described spool makes the 2nd O shape circle on described spool contact with the conical surface of described one-way valve valve body.
As further improvement of the utility model, described one-way valve valve inner has the conical surface of 60 °, and described 2nd O shape circle is arranged on the position corresponding with described spool.
As further improvement of the utility model, described spring is regulated by described spring swivel nut.
As further improvement of the utility model, carbon dioxide steel cylinder valve gas pressure in steel cylinder is closed automatically when 0.2MPa ~ 0.4MPa, automatically opens when 0.6 ~ 0.8MPa.
The beneficial effects of the utility model are: the self-closing device of carbon dioxide steel cylinder valve of the present utility model, and sealing is tight, can realize automatic closedown, easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the self-closing device of carbon dioxide steel cylinder valve of the present utility model;
By reference to the accompanying drawings, make the following instructions:
1---one-way valve valve body; 2---an O shape circle; 3---the 2nd O shape circle; 4---spool; 5---seal ring; 6---spring; 7---spring swivel nut.
Embodiment
As shown in Figure 1, the self-closing device of the carbon dioxide steel cylinder valve of the utility model specific embodiment, the spring swivel nut 7 that its position, air outlet being included in valve sets gradually successively from inside to outside, spring 6, spool 4, one-way valve valve body 1, an O shape circle 2 and the 2nd O shape circle 3, spring 6 is positioned at spring swivel nut 7, and spring 6 promotes spool 4 makes the 2nd O shape circle 3 on spool 4 contact with the conical surface of one-way valve valve body 1.
In the utility model specific embodiment, there is the conical surface of 60 ° one-way valve valve body 1 inside, and the 2nd O shape circle 3 is arranged on the position corresponding with spool 4.Spring 6 is regulated by spring swivel nut 7.Carbon dioxide steel cylinder valve gas pressure in steel cylinder is closed automatically when 0.2MPa ~ 0.4MPa, automatically opens when 0.6 ~ 0.8MPa.
Particularly, as shown in Figure 1, when valve is in opening state, when steel cylinder internal pressure is greater than 0.8MPa, promote spool 4 by air pressure and move, now air pressure is greater than the elastic force of spring 6 to spool 4 pressure, and Compress Spring 6, makes one-way valve opens; When steel cylinder internal pressure is less than 0.4MPa, now the elastic force of spring 6 is greater than air pressure to spool 4 pressure, and spring 6 promotes spool, the conical surface of the 2nd O shape circle 3 on spool and one-way valve valve body 1 is contacted, ensures sealing, thus play self-closing effect.
The beneficial effects of the utility model are: the self-closing device of carbon dioxide steel cylinder valve of the present utility model, and sealing is tight, can realize automatic closedown, easy to operate.
Above embodiment is with reference to accompanying drawing, is described in detail to preferred embodiment of the present utility model.Those skilled in the art by carrying out amendment on various forms or change to above-described embodiment, but when not deviating from essence of the present utility model, drops within protection domain of the present utility model.
