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, and described connection end includes the bigger diameter end being connected with valve seat and external diameter is less than bigger diameter end and company
It is connected on the miner diameter end of bigger diameter end outer end；Described bigger diameter end is concentric with miner diameter end；Described connecting tube includes body, is connected to body
One end and have externally threaded corrugated tubing and outer connecting pipe；Described outer connecting pipe and corrugated tubing are connected to same one end of body；
Outer connecting pipe internal diameter is more than miner diameter end external diameter；Described outer connecting pipe outer end is connected with terminal pad；Described bigger diameter end outer end has puts
Put annular groove；Described placement annular groove hose lining is connected to sealing ring；Behind corrugated tubing threaded connection end, described sealing ring and terminal pad
It is close to, terminal pad is connected with bigger diameter end by bolt；Between described body and bigger diameter end, lock washer is installed；Described locking pad
Circle is located between outer connecting pipe and miner diameter end.
Its connection screw thread pipe end of described body has closure gasket groove；It is connected with sealing ring in described closure gasket groove.
What this utility model can reach has the technical effect that：It is provided with locking between body of the present utility model and bigger diameter end
Packing ring, and terminal pad is connected with bigger diameter end by bolt, can effectively prevent connecting tube from getting loose；And water is effectively prevented by sealing ring
Enter between outer connecting pipe and miner diameter end it is ensured that lock washer is difficult to get rusty, service life is longer.
Brief description
With reference to the accompanying drawings and detailed description this utility model is described in further detail：
Fig. 1 is the structural representation of a kind of 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 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, 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 two ends are all connected with
Connect end 5；Female thread is had in described connection end 5；Connection end 5 is threaded with connecting tube 6, and described connection end 5 includes and valve seat 1
The bigger diameter end 11 connecting and external diameter are less than bigger diameter end 11 and are connected to the miner diameter end 12 of bigger diameter end 11 outer end；Described bigger diameter end 11
Concentric with miner diameter end 12；Described connecting tube 6 includes body 21, is connected to body 21 one end and has externally threaded corrugated tubing 22
And outer connecting pipe 23；Described outer connecting pipe 23 and corrugated tubing 22 are connected to same one end of body 21；Outer connecting pipe 23 internal diameter is big
