Abstract
The utility model provides a locking valve, includes the disk seat, disk seat one end all is connected with opens the link that has the external screw thread, it has the connecting pipe to connect end screw thread connection, the link includes the outer intubate of being connected with the disk seat and connects at extrapolation outside of tubes end and open the thread end that has the external screw thread, outer intubate, thread end and disk seat integrated into one piece, the extrapolation external diameter of pipe is greater than the thread end external diameter, the connecting pipe is opened there is the fixed slot, through first bolt fastening rubber sleeve on the fixed slot, when the thread end with be connected pipe thread connection after well, the rubber sleeve card is in outer intubate to through second bolt and extrapolation union coupling. The utility model discloses the thread end with be connected pipe thread connection, both connect good back, use first bolt and the 2nd bolted connection connecting pipe and outer intubate respectively through the rubber sleeve, guarantee that connecting pipe and link are connected and be difficult for becoming flexible.
Description
Technical field
This utility model is related to a kind of locking valve.
Background technology
Existing valve includes valve seat and the connection end being connected with valve seat, connecting tube be threaded connection connection end and with
Valve connects, but with long afterwards, connection end is easily got loose with connecting tube threaded connection place, causes to leak.
Utility model content
This utility model is exactly to solve the problems, such as to provide a kind of connecting tube to be difficult loosening locking valve gate technology.
For solving above-mentioned technical problem, a kind of technical solution of locking valve of this utility model is：
Including valve seat, the valve rod that is connected with valve ball of the valve ball that is arranged in valve seat and handle, described valve rod one end connects
The valve ball other end passes through valve seat to connect handle, and described valve seat one end is all connected with and has externally threaded connection end；Described connection end
It is threaded with connecting tube, described connection end is included the outer tube being connected with valve seat and is connected to outer tube outer end and has outer
The end of thread of screw thread；Described outer tube, the end of thread and valve seat are integrally formed；Described outer tube external diameter is more than end of thread external diameter；
Described connecting tube has fixing groove；First bolt is passed through on described fixing groove and fixes rubber sleeve；When the end of thread and connecting tube spiral shell
After stricture of vagina connects, described rubber sleeve is stuck on outer tube, and is connected with outer tube by the second bolt.
Between described connecting tube and outer tube, sealing ring is installed.
Described outer tube is included outside and is provided with snap ring and the clamping pipe that is connected with the end of thread and be connected to clamping pipe and valve
Fixing pipe between seat；Described rubber sleeve is connected with fixing pipe by the second bolt.
What this utility model can reach has the technical effect that：This utility model end of thread is threadeded with connecting tube, two
After person connects, by rubber sleeve respectively with the first bolt and the second bolt connection connecting tube and outer tube it is ensured that connecting tube
It is connected with connection end and be difficult to loosen.
Brief description
With reference to the accompanying drawings and detailed description this utility model is described in further detail：
Fig. 1 is a kind of structural representation of locking valve of this utility model；
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is made with further details of elaboration.
Refering to Fig. 1,2.
A kind of locking valve, including valve seat 1, the valve rod 3 that is connected with valve ball 2 of the valve ball 2 that is arranged in valve seat 1 and handss
Handle 4, described valve rod 3 one end connects valve ball 2 other end and passes through valve seat 1 to connect handle 4, and described valve seat 1 one end is all connected with and has
Externally threaded connection end 5；Described connection end 5 is threaded with connecting tube 6, and described connection end 5 includes the extrapolation being connected with valve seat 1
Pipe 11 and be connected to outer tube 11 outer end and have the externally threaded end of thread 12；Described outer tube 11, the end of thread 12 and valve
Seat 1 is integrally formed；Described outer tube 11 external diameter is more than the end of thread 12 external diameter；Described connecting tube 6 has fixing groove 7；Described fixation
On groove 7, rubber sleeve 9 is fixed by the first bolt 8；After the end of thread 12 has been threadeded with connecting tube 6, described rubber sleeve 9 blocks
On outer tube 11, and it is connected with outer tube 11 by the second bolt 10.
Between described connecting tube 6 and outer tube 11, sealing ring 21 is installed；Described sealing ring 21 is teflon seal
Circle.
Described outer tube 11 is included outside and is provided with snap ring 31 and the clamping pipe 32 that is connected with the end of thread 12 and be connected to card
Fixing pipe 33 between adapter 32 and valve seat 1；Described rubber sleeve 9 is connected with fixing pipe 33 by the second bolt 10.
Using method：Connecting tube 6 of the present utility model adopts metal connecting tube, is first glued to rubber sleeve 9 in advance solid
Determine on groove 7, preferably, rubber sleeve 9 is connected with connecting tube 6 by the first bolt 8 again；And in the end of thread 12 and connecting tube 6 spiral shell
After stricture of vagina connects, rubber sleeve 9 is stuck on clamping pipe 32, and is connected with outer tube 11 by the second bolt 10；Described rubber sleeve 9 leads to
Cross dual fixation, make connecting tube 6 be difficult to rotate against with the end of thread 12, that is, be difficult to loosen.
