Abstract
The utility model relates to a non-repeat filling bottle valve for a pressure container and comprises a valve body and a valve rod which is arranged in the valve body and shifts a valve core, wherein the valve rod is matched with the valve body through a screw thread. A sealing component is arranged between the valve rod and the valve body, and a valve core component is arranged between a liquid inlet and a liquid outlet. The valve core component comprises the valve core, a supporting component and an elastic sealing component, wherein the valve core has the spherical shape. The lower part of the valve core is provided with the supporting component, and the supporting component is provided with a hole with an inner diameter which is slightly smaller than the diameter of the valve core. A through hole for the passing process of medium is arranged on the outer edge of the hole, and the lower part of the supporting component is provided with the elastic sealing component. The elastic sealing component is also provided with a hole for the passing process of the medium, and the shape of the elastic sealing component is matched with the shape of the valve core. The non-repeat filling bottle valve for a pressure container has the advantage of simple structure and can effectively and reliably prevent the non-repeat filling process.
Description
(1) technical field
The utility model relates to a kind of cylinder valves for non-refillable cylinder, especially a kind of pressurized container cylinder valves for non-refillable cylinder.
(2) background technique
The pressurized container cylinder valves for non-refillable cylinder, be particularly suitable in oil, chemical industry, the pharmaceuticals industry, be installed in non-refillable steel cylinder or similar disposable bottle and irritate upward matching used, be to avoid filling the vitals that bottle is reused the serious harm personal safety that is brought with it.
(3) summary of the invention
In order to overcome cylinder valves for non-refillable cylinder in the prior art, the deficiency of complex structure, non-refillable reliability, the utility model provides a kind of simple in structure, pressurized container cylinder valves for non-refillable cylinder that can prevent non-refillable effectively, reliably.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of pressurized container cylinder valves for non-refillable cylinder, comprise valve body, be installed in the valve body, stir the valve rod of spool, valve rod cooperates with valve body by screw thread, be provided with Sealing between valve rod and valve body, be provided with mangetic core assembly between liquid entering hole and the liquid outlet, described mangetic core assembly comprises spool, supporting element, elastomer seal, spool is spherical, and the spool bottom is provided with supporting element, has the hole that internal diameter is slightly less than valve core diameter on the supporting element, the outer in hole is provided with the through hole that passes through for medium, the supporting element bottom is provided with elastomer seal, and elastomer seal has hole, the shape of elastomer seal and the form fit of passing through for medium of spool.
The sidewall of described elastomer seal is a bowl-type.
Described valve body lower end and the welding of non-refillable steel cylinder.
Pressurized container described in the utility model mainly shows with the beneficial effect of cylinder valves for non-refillable cylinder: 1, spool is made as sphere, spool is divided into supporting element, by the precession valve rod spool is clamp-oned the purpose that realizes non-refillable in the supporting element, simple in structure, practical reliable; 2, supporting element has the elastomer seal good reliability.
(4) description of drawings
To be the utility model pressurized container fill preceding phase diagram with the medium of cylinder valves for non-refillable cylinder to Fig. 1.
To be the utility model pressurized container fill the back phase diagram with the medium of cylinder valves for non-refillable cylinder to Fig. 2.
Phase diagram when Fig. 3 is the utility model pressurized container with the media discharge of cylinder valves for non-refillable cylinder.
Fig. 4 is the anti-repeated charging phase diagram of the utility model pressurized container with cylinder valves for non-refillable cylinder.
Fig. 5 is the structural representation of the utility model pressurized container with the supporting element of cylinder valves for non-refillable cylinder.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to accompanying drawing: a kind of pressurized container cylinder valves for non-refillable cylinder, comprise valve body 1, be installed in the valve body, stir the valve rod 2 of spool, valve rod 2 cooperates with valve body 1 by screw thread, 1 of valve rod 2 and valve body are provided with Sealing 3, be provided with mangetic core assembly between liquid entering hole 4 and the liquid outlet 5, described mangetic core assembly comprises spool 6, supporting element 7, elastomer seal 8, spool 6 is spherical, and spool 6 bottoms are provided with supporting element 7, have the hole that internal diameter is slightly less than valve core diameter on the supporting element 7, the outer in hole is provided with the through hole 9 that passes through for medium, supporting element 7 bottoms are provided with elastomer seal 8, and elastomer seal has hole, the shape of elastomer seal and the form fit of passing through for medium of spool.
The sidewall of described elastomer seal 8 is a bowl-type.
Described valve body lower end and the welding of non-refillable steel cylinder.
Before medium filled, medium entered valve body from valve nozzle, charged into steel cylinder through the groove of supporting element, and after medium had filled, firmly the precession valve rod pushed up on the spool it, and spool is squeezed in the supporting element, and is pressed on the elastomer seal.If will use the medium in the bottle, unscrew valve rod, pressure medium up pushes up spool, and medium normally flows out through the groove of supporting element.If think to fill once more medium, because at this moment spool can be free movable, the pressure of medium can make spool push elastomer seal downwards, blocks the air outlet, can't fill once more.
Claims (3)
1, a kind of pressurized container cylinder valves for non-refillable cylinder, comprise valve body, be installed in the valve body, stir the valve rod of spool, valve rod cooperates with valve body by screw thread, be provided with Sealing between valve rod and valve body, be provided with mangetic core assembly between liquid entering hole and the liquid outlet, it is characterized in that: described mangetic core assembly comprises spool, supporting element, elastomer seal, spool is spherical, and the spool bottom is provided with supporting element, has the hole that internal diameter is slightly less than valve core diameter on the supporting element, the outer in hole is provided with the through hole that passes through for medium, the supporting element bottom is provided with elastomer seal, and elastomer seal has hole, the shape of elastomer seal and the form fit of passing through for medium of spool.
