Abstract
The present invention discloses a kind of self-closing standard cylinder valve, the valve body of the cylinder valve is formed with lateral connector, if a connector sleeve, one end of connector sleeve is formed with the external screw thread being threadedly coupled with connector, the other end is formed with the internal screw thread being threadedly coupled with pressure reducing valve, the sliding sleeve of sliding is equipped in the external thread section of connector sleeve, sliding sleeve has the blind hole of outer end opening, the inner end of sliding sleeve is installed with the sealing ring for blocking connector sleeve inner port, the through-hole of connection blind hole is offered on close to the sliding sleeve side wall on the outside of sealing ring, compressed spring is installed between the inner end of connector and the inner end of sliding sleeve, the external port of sliding sleeve is set as horn mouth.Since present invention employs connector sleeve connections seperated with the connector of cylinder valve valve body, check valve is installed in connector sleeve, therefore the horn mouth of check valve is just not necessarily to open up the notch for inserting stubborn tool, and when connecting pressure reducing valve, smooth horn mouth would not also damage the rubber mat of plugging into of pressure reducing valve.
Description
Technical field
The present invention relates to bottle valve technical fields, refer in particular to self-closing bottle valve.
Background technique
Standard cylinder valve is a kind of bottle valve that civilian family generally uses, and the connector of pressure reducing valve and cylinder valve is all using spiral shell
Line connection.For the security performance that enhancing gas cylinder uses, this standard cylinder valve can install check valve additional in connector, to prevent in bottle
Gas leak.When connecting pressure reducing valve, the connector of pressure reducing valve can open the spool of check valve, be connected to bottle valve.Wherein check valve
The connecting pin of connection pressure reducing valve is mostly set as horn mouth connection.Since the connector of standard cylinder valve is usually all and valve body one
, therefore check valve is typically all to use thread connecting mode that the valve body of check valve is screwed into connector.Check valve in this way
Flared end needs to open up the notch for inserting stubborn tool, and after connecting pressure reducing valve, which can damage the glue on pressure reducing valve connector
Pad.
Summary of the invention
The technical problem to be solved in the present invention is to provide the self-closing standard jars that one kind will not damage pressure reducing valve connection rubber mat
Valve.
Used technical solution to solve above-mentioned technical problem: a kind of self-closing standard cylinder valve, the valve body of the cylinder valve
It is formed with lateral connector, it is characterised in that: set a connector sleeve, one end of connector sleeve is formed with to be threadedly coupled with connector
External screw thread, the other end are formed with the internal screw thread being threadedly coupled with pressure reducing valve, the sliding sleeve of sliding are equipped in the external thread section of connector sleeve,
Sliding sleeve has the blind hole of outer end opening, and the inner end of sliding sleeve is installed with the sealing ring for blocking connector sleeve inner port, close to outside sealing ring
The through-hole that connection blind hole is offered on the sliding sleeve side wall of side, is equipped with compression bullet between the inner end of connector and the inner end of sliding sleeve
The external port of spring, sliding sleeve is set as horn mouth.
Using brought by the present invention the utility model has the advantages that since present invention employs the connectors of connector sleeve and cylinder valve valve body point
Body connection, check valve are installed in connector sleeve, therefore the horn mouth of check valve is just not necessarily to open up the notch for inserting stubborn tool, is connecting
When pressure reducing valve, smooth horn mouth would not also damage the rubber mat of plugging into of pressure reducing valve.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of self-closing standard cylinder valve of the present invention.
Specific embodiment
As shown in Figure 1, a kind of self-closing standard cylinder valve, the valve body 1 of the cylinder valve is formed with lateral connector 11.If one
Connector sleeve 2, one end of connector sleeve 2 are formed with the external screw thread being threadedly coupled with connector 11, and the other end is formed with pressure reducing valve (often
Component is advised, is not indicated in figure) internal screw thread that is threadedly coupled.The sliding sleeve 3 of sliding is equipped in the external thread section of connector sleeve 2.Sliding sleeve 3 has
There is the blind hole 31 of outer end opening.The inner end of sliding sleeve 3 is installed with the sealing ring 4 for blocking 2 inner port of connector sleeve.Close to outside sealing ring 4
The through-hole 32 of connection blind hole 31 is offered on 3 side wall of sliding sleeve of side.It is equipped between the inner end of connector 11 and the inner end of sliding sleeve 3
Compressed spring 5, the spring 5 keep sliding sleeve 3 to slide in and out trend.The external port of sliding sleeve 3 is set as horn mouth 33.To guarantee standard jar
The leakproofness of valve should also install sealing additional between connector 11 and connector sleeve 2 and between the sliding surface and connector sleeve 2 of sliding sleeve 3
Circle 6.
Sliding sleeve 3 and seal chamber 4 constitute check valve, and the inner port for being connected set 2 is stuck in connector sleeve 2.In this way, passing through company
The installation of female connector 2 achieves that the installation of check valve, and the notch for inserting stubborn tool is opened up without 33 end of horn mouth in sliding sleeve 3,
The connection rubber mat of pressure reducing valve would not be damaged.
When installing pressure reducing valve, the connection connector sleeve 2 of the connector insertion cylinder valve of pressure reducing valve is inserted into, and is rotated on pressure reducing valve
Outer tooth nut is tightened with connector sleeve 2.The end of plugging into of connector can head on 3 retraction of sliding sleeve, and check valve is opened, while making 3 side of sliding sleeve
The through-hole 32 of wall is connected to blind hole 31 and 11 inner cavity of connector, is connected to pressure reducing valve with cylinder valve.After removing pressure reducing valve, in spring 5
Under the action of, sliding sleeve 3 stretches out, and sealing ring 4 is pressed on the inner port of sliding sleeve 3, and closed check valve prevents gas leak in bottle.
