Description
Technical field
The utility model relates to bottle valve technical field, the bottle valve with quick connector is referred in particular to.
Background technique
Traditional bottle valve is connect generally by threaded connection with pressure reducing valve, and this mode is troublesome in poeration, is connected bad
It is easy to appear leakage problem.Thus, have at present using the interface mode quickly connected, and check valve is installed in interface,
To prevent gas from leaking.This mode is easy to operate, and anti-to let out effect good.But the current list for connecing bottle valve fastly
The check valve of core bar mode is usually used to valve, the air flue of this check valve is typically more narrow, often has foreign matter and exists
On core bar air flue, cause closed check valve not tight, leak air problem.
Utility model content
Prevent letting out the good bottle valve of effect the technical problem to be solved by the present invention is to provide a kind of.
Used technical solution to solve above-mentioned technical problem: the valve body of a kind of bottle valve, the bottle valve is formed with
Quick connector is equipped with the check valve for preventing gas leak in quick connector, it is characterised in that: the check valve includes
Block set, sliding sleeve and footstock, block set are fixedly connected with the bore inner walls of quick connector, and the vestibule of block set and quick connector
Sealing ring is equipped between inner wall, block set is formed with two-stage sliding sleeving hole, wherein small, the sliding sleeve of the aperture ratio outer segment of the sliding sleeving hole of inner segment
It is formed with the two-stage sliding sleeve being slidably matched respectively with the two-stage sliding sleeving hole of block set, and the length of small sliding sleeve is longer than small sliding sleeving hole
Length, the side wall of small sliding sleeve offer through-hole, and the end of small sliding sleeve is fixedly connected with footstock, and fixed between small sliding sleeve and footstock
There is the gasket for sealing small sliding sleeving hole port, compressed spring be installed between footstock and the vestibule inner end of quick connector,
The periphery wall of big sliding sleeve is equipped with sealing ring.
Using brought by the utility model the utility model has the advantages that due to the utility model use sliding sleeve as spool, and
Sliding sleeve side wall offers the through-hole for ventilating, so that gas passage is very free from worry, the flowing of gas is smooth, can avoid foreign matter
Choked flow road solves the problems, such as that closed check valve is not tight, prevents gas cylinder gas leak phenomenon.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model bottle valve；
Fig. 2 is the structural schematic diagram of block set in the utility model；
Fig. 3 is the structural schematic diagram of sliding sleeve in the utility model.
Specific embodiment
As shown in Figure 1-3, a kind of bottle valve, the valve body 1 of the bottle valve is formed with quick connector 11, quick connector
The check valve for preventing gas leak is installed in 11.In the present invention, the check valve include block set 2, sliding sleeve 3 and
Footstock 4, block set 2 are fixedly connected with the bore inner walls of quick connector 11, fixed form use be threadedly coupled, and block set 2 with
It is equipped with sealing ring 5 between the bore inner walls of quick connector 11, block set 2 is formed with two-stage sliding sleeving hole, wherein the sliding sleeving hole of inner segment
21 aperture ratio outer segment sliding sleeving hole 22 is small, and it is sliding that sliding sleeve 3 is formed with the two-stage being slidably matched respectively with the two-stage sliding sleeving hole of block set 2
Set, and the length of small sliding sleeve 31 is longer than the length of small sliding sleeving hole 21, the side wall of small sliding sleeve 31 offers through-hole 31.1, small sliding sleeve
31 end is fixedly connected with footstock 4, and is fixed between small sliding sleeve 31 and footstock 4 for sealing the close of small 21 port of sliding sleeving hole
Packing 6 is equipped with compressed spring 7 between footstock 4 and quickly the vestibule inner end of connector 11, and the periphery wall of big sliding sleeve 32 is equipped with
Sealing ring 8.
When pressure reducing valve is installed, in the quick connector 11 of the fast connector insertion bottle valve of pressure reducing valve, fast connector
Plunger tip can head on sliding sleeve 3 slide into valve body 1 in, since the length of the small sliding sleeve 31 of sliding sleeve 3 is longer than the small sliding sleeving hole 21 of block set 2
Length, the through-hole 31.1 on sliding sleeve 31 small in this way can slip over that section of small sliding sleeving hole 21, be connected to the inner end of quick connector 11.
Bottle valve is connected to by 3 inner cavity of sliding sleeve with through-hole 31.1 with pressure reducing valve in this way.And after pulling up the fast connector of pressure reducing valve, in bullet
Under the action of spring 7, sliding sleeve 3 is skidded off, and gasket 6 is pressed on small 21 port of sliding sleeving hole by footstock 4, and air flue is closed.To increase gas
Body channel, through-hole 31.1 can be multiple along the laying of the peripheral wall of small sliding sleeve 31, so that the flowing of gas is smooth, avoid foreign matter choked flow
Road solves the problems, such as that closed check valve is not tight, prevents gas cylinder gas leak phenomenon.
