Description

A kind of locking pair of internal thread valve
Technical field
This utility model is related to a kind of locking pair of internal thread valve.
Background technology
Existing pair of internal thread valve includes valve seat and the connection end being connected with valve seat, and connecting tube is threaded connection connection Hold and be connected with valve, but with long afterwards, connection end and connecting tube threaded connection place easily get loose, cause 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 the double internal thread valve gate technology getting loose.
For solving above-mentioned technical problem, a kind of technical solution of locking pair of internal thread 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 two ends are all connected with connection end;Female thread is had in described connection end; Connection end is threaded with connecting tube, also includes gland;Described connecting tube includes body, is connected to body one end and has outer spiral shell The corrugated tubing of stricture of vagina;That described connection end includes being connected with valve seat and open female riffled tube and with riffled tube outer end The trocar sheath connecting;Annular groove is had inside described trocar sheath outer end;The rubber snap ring having annular groove is gluedd joint in described annular groove;Institute State and outside body, be provided with the fixture block being integrated with itself;After corrugated tubing has been threadeded with riffled tube, described fixture block is stuck in In annular groove;Described gland is placed on body and compresses fixture block;Described gland is bolted trocar sheath.
Between described corrugated tubing and valve seat, sealing ring is installed.
Described bolt is 4.
Described valve seat, riffled tube and trocar sheath are integrally formed.
What this utility model can reach has the technical effect that:It is good that this utility model is threadeded with riffled tube in corrugated tubing Afterwards, fixture block is stuck in annular groove, prevents from getting loose by fixture block, further prevents fixture block from getting loose by gland, and gland passes through Bolt connection trocar sheath, can effectively prevent connecting tube from getting loose.
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 pair of internal thread 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 pair of internal thread 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 handle 4, through valve seat 1 connection handle 4, described valve seat 1 two ends all connect described valve rod 3 one end connection valve ball 2 other end There is connection end 5;Female thread is had in described connection end 5;Connection end 5 is threaded with connecting tube 6, also includes gland 7;Described company Adapter 6 includes body 21, is connected to body 21 one end and has externally threaded corrugated tubing 22;Described connection end 5 includes and valve seat 1 Connect and open female riffled tube 11 and the trocar sheath 12 being connected with riffled tube 11 outer end;Described trocar sheath 12 Annular groove is had inside outer end;The rubber snap ring 13 having annular groove 14 is gluedd joint in described annular groove;Be provided with outside described body 21 with The fixture block 23 itself being integrated;After corrugated tubing 22 has been threadeded with riffled tube 11, described fixture block 23 is stuck in annular groove 14 Interior;Described gland 7 is placed on body 21 and compresses fixture block 23;Described gland 7 passes through bolt 8 outer sleeve for connecting 12.
Between described corrugated tubing 22 and valve seat 1, sealing ring 9 is installed.
Described bolt 8 is 4.
Described valve seat 1, riffled tube 11 and trocar sheath 12 are integrally formed.
Using method:This utility model is threadeded with riffled tube 11 by corrugated tubing 22, makes connecting tube 6 and connection end 5 is threaded;And be stuck in annular groove 14 by fixture block 23, so that connecting tube 6 is stuck in connection end 5, be difficult to loosen;In order to reach Preferably anti-loosing effect, gland 7 passes through bolt 8 outer sleeve for connecting 12, and at this moment, gland 7 is placed on body 21 and compresses card Block 23, anti-loosing effect preferably, and is provided with sealing ring 9 it is ensured that connecting tube 6 is connected with connection end 5 between corrugated tubing 22 and valve seat 1 The sealing at place, described sealing ring 9 is teflin ring.
