Abstract
The present invention discloses a kind of self-closing bottle valve, the valve body of bottle valve is formed with connector, check valve is installed in connector, check valve includes block set and sliding sleeve, block set is fixedly connected with connector, and sealing ring is equipped between block set and connector, sliding sleeve has the blind hole of logical outer end, the inner end of sliding sleeve is equipped with the sealing ring for blocking block set, and the side wall of sliding sleeve offers the through-hole of connection blind hole, the closure face of block set is set as bell mouth shape, and compressed spring is equipped between the inner end and connector of sliding sleeve, and the periphery wall of sliding sleeve is equipped with sealing ring.Since the check valve of bottle valve of the present invention is made of block set and sliding sleeve, the channel of the blind hole of sliding sleeve and the through-hole of side wall as air-flow so that gas passage is very free from worry, and the flowing of gas is smooth, can avoid foreign body from blocking runner, solves the problems, such as that closed check valve is not tight.Also the closure face of block set is set as bell mouth shape, coordinates with the sealing ring of sliding sleeve inner end, has excellent sealing effect, prevent gas cylinder gas leak phenomenon.
Description
Technical field
The present invention relates to bottle valve technical fields, refer in particular to self-closing bottle valve.
Background technology
To prevent gas from leaking, check valve is installed in the connector of current bottle valve connection pressure reducing valve.Connection decompression
After valve, the connector of pressure reducing valve can open-top check valve；After removing pressure reducing valve, check valve is automatically closed.But this bottle valve
The check valve of core bar mode is usually used in check valve, and the air flue of this check valve is typically more narrow, often has foreign matter
On core bar air flue, cause closed check valve not tight, leak air problem.
Invention content
Prevent letting out the good bottle valve of effect the technical problem to be solved in the present invention is to provide a kind of.
Used technical solution to solve above-mentioned technical problem：A kind of self-closing bottle valve, the valve body of the bottle valve
It is formed with connector, the check valve for preventing gas leak is installed in connector, it is characterised in that：The check valve includes set
Seat and in the sliding sleeve slided in block set, block set is fixedly connected with the bore inner walls of connector, and the vestibule of block set and connector
Sealing ring is equipped between inner wall, sliding sleeve has the blind hole of logical outer end, and the inner end peripheral wall of sliding sleeve, which is equipped with, blocks block set inner port
Sealing ring, and the side wall of sliding sleeve offers the through-hole of connection blind hole, the closure face of block set are set as bell mouth shape, the inner end of sliding sleeve with
Compressed spring is installed, the periphery wall of sliding sleeve is equipped with sealing ring between the vestibule inner end of connector.
Using advantageous effect caused by the present invention：Since the check valve of bottle valve of the present invention is made of block set and sliding sleeve,
The channel of the blind hole of sliding sleeve and the through-hole of side wall as air-flow so that gas passage is very free from worry, and the flowing of gas is smooth, can keep away
Exempt from foreign body from blocking runner, solves the problems, such as that closed check valve is not tight.Also the closure face of block set is set as bell mouth shape, in sliding sleeve
The sealing ring at end coordinates, and has excellent sealing effect, prevents gas cylinder gas leak phenomenon.
Description of the drawings
Fig. 1 is the structural schematic diagram of self-closing bottle valve of the present invention；
Fig. 2 is the structural schematic diagram of block set in the present invention；
Fig. 3 is the structural schematic diagram of sliding sleeve in the present invention.
Specific implementation mode
As shown in Figs. 1-3, the valve body 1 of a kind of self-closing bottle valve, the bottle valve is formed with connector 11, connector 11
Inside being equipped with prevents the check valve of gas leak.In the present invention, the check valve includes block set 2 and in sliding in block set 2
Dynamic sliding sleeve 3, block set 2 are fixedly connected with the bore inner walls of connector 11, and are set between block set 2 and the bore inner walls of connector 11
There are sealing ring 4, sliding sleeve 3 that there is the blind hole 31 of logical outer end, the inner end peripheral wall of sliding sleeve 3 to be equipped with the sealing for blocking 2 inner port of block set
Circle 5, and the side wall of sliding sleeve 3 offers the through-hole 32 of connection blind hole 31, the closure face 21 of block set 2 is set as bell mouth shape, sliding sleeve 3
Compressed spring 6 is installed, the periphery wall of sliding sleeve 3 is equipped with sealing ring 7 between inner end and the vestibule inner end of connector 11.
When installing pressure reducing valve, the connector of pressure reducing valve is inserted into the connector 11 of bottle valve, and the plunger tip of connector can head on
Sliding sleeve 3 slides in valve body 1, and the through-hole 32 of 3 side wall of sliding sleeve is made to be connected to 11 inner cavity of connector, and check valve is opened.And pull up pressure reducing valve
Connector after, under the action of spring 6, sliding sleeve 3 skids off, and the sealing ring 5 of 3 inner end of sliding sleeve is pressed on horn-like port
On, closed check valve.To increase gas passage, through-hole 32 can be laid multiple along the peripheral wall of sliding sleeve 3 so that the flowing stream of gas
Freely, foreign body from blocking runner is avoided, solves the problems, such as that closed check valve is not tight, prevents gas cylinder gas leak phenomenon.
