Abstract
The utility model relates to a safety valve, which adopts the technical proposal that: the valve is made of metal and hot-resistance and fireproof material; self-developing explosion proof safety film is assembled in a valve body; when the pressure exceeds the design pressure, the safety valve opens automatically to avoid the explosion harm on a human body caused by the overhigh pressure in a gas cylinder, and a needle type sealing valve and a sealing needle bar arranged on the gas cylinder are integrated. The utility model has the advantages of small sealing area, good sealing performance, flexible switch, no dislocation and no peeling and improvement of sealing performance.
Description
Technical field:
The utility model relates to a kind of gas cylinder pin type sealed valve.
Background technique:
The used gas cylinder valve of domestic present society all adopts ball-type and working of plastics sealed type oxygen valve, and Security is relatively poor, causes accidents such as burning, blast easily, and the personnel that cause injure.And the spheroid and the valve rod of Sealing easily misplace, come off, and influence is normally used; Poor sealing performance, the resistance that operates is bigger.Its reason is backward in technique, and the material of use is improper.
Summary of the invention:
Existing gas cylinder valve Security is low easily to cause the accident in order to overcome, operation is painstaking during use, the fragile deficiency that causes sealing gas leakage of parts, the utility model provides a kind of gas cylinder pin type sealed valve, this valve has not only effectively improved the Safety performance of gas cylinder valve, and easy to use, accessory is not fragile, has effectively improved sealability.
The technological scheme that the technical problem that solved the utility model adopts is, adopt metal and high temperature resistant anti-burning material, and in valve body, assembled the anti-explosion safety film of development voluntarily, when pressure surpasses design pressure, safety valve is opened automatically, has avoided the injury that human body is caused because of the too high generation blast of gas cylinder internal pressure.Gas cylinder pin type sealed valve sealing shank has adopted the design of pin, bar one, the little good seal performance of its seal point, switch light and flexible in addition.Not misplacing does not come off, and has effectively improved sealability.
Description of drawings:
The combination schematic representation and the title thereof of each parts of gas cylinder pin type sealed valve
1, valve body 2, " O " type circle 3, back-up ring 4, swivel nut 5, shank 6, locking cap 7, handwheel 8, pad 9, screw 10, safety valve diaphragm 11, cosmetic sheet 12, safety valve bolt
Embodiment:
Valve body 1 upper end is put into " O " type circle 2 and back-up ring 3 successively in the accompanying drawings, and locks with locking swivel nut 4.To insert shank 6 usefulness locking caps 6 then locks.At last handwheel 7 usefulness pads 8 and screw 9 are fixed on shank 5 afterbodys, and on handwheel 7, stick cosmetic sheet 11.Safety valve diaphragm 10 is put into the left side of valve body 1 and tightened safety valve bolt 12.
Claims (2)
1. a gas cylinder pin type sealed valve is characterized in that, " O " type circle in the conical surface that utilizes a valve rod and the shank that links together of sealing syringe needle and the valve body and back-up ring interlock are mutually realized sealing.
2. gas cylinder pin type sealed valve according to claim 1 is characterized in that having installed the safety valve diaphragm of metal in valve body.
