Description

A kind of double outer silk valve

Technical field

This utility model is related to a kind of double outer silk valve.

Background technology

The connection end that existing double outer silk valve is included valve seat and is connected with valve seat, 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 and 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 outer silk valve gate technology getting loose.

For solving above-mentioned technical problem, a kind of technical solution of double outer silk valves 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；Described connection end has external screw thread；Even Connect end and be threaded with connecting tube, described valve seat includes valve seat body and the joint end of difference connecting valve seat body；Described card Connect end one end connecting valve seat body other end and connect connection end；Described joint end external diameter is more than connection end external diameter；Described joint end The fixing annular groove having by the side of connection end；It is connected with spring washer in described fixing annular groove；Described connecting tube leans on joint end Side has the containing cavity for placing spring washer；Between described connecting tube and joint end, sealing ring is installed；When connecting tube with After connection end is threaded, outside described connecting tube and joint end, it is cased with rubber card set.

It is provided with the first snap ring being integrated with itself outside described joint end；Set outside its threaded ends of described connecting tube There is the second snap ring being integrated with itself.

Described connection end, valve seat body and joint end are integrally formed.

Described sealing ring is gluedd joint with joint end.

What this utility model can reach has the technical effect that：Between connecting tube of the present utility model and joint end, bullet is installed Spring packing ring can prevent connecting tube thread looseness, and is provided with sealing ring between connecting tube and joint end, and in connecting tube and clamping End is outer to be cased with rubber card set, can prevent water from entering accommodating intracavity, effectively prevent spring washer from getting rusty, service life is more long.

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 double outer silk valves 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 double outer silk 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；Described connection end 5 has external screw thread；Connection end 5 is threaded with connecting tube 6, and described valve seat 1 includes valve seat body 11 And the joint end 12 of difference connecting valve seat body 11；Described joint end 12 one end connecting valve seat body 11 other end connects End 5；Described joint end 12 external diameter is more than connection end 5 external diameter；Described joint end 12 leans on the fixing annular groove that the side of connection end 5 has 7；It is connected with spring washer 8 in described fixing annular groove 7；Described connecting tube 6 has for placing spring washer 8 by joint end 12 side Containing cavity 9；Between described connecting tube 6 and joint end 12, sealing ring 13 is installed；When connecting tube 6 is threadeded with connection end 5 Afterwards, it is cased with rubber card set 14 outside described connecting tube 6 and joint end 12.

Preferably, being provided with the first snap ring 21 being integrated with itself outside described joint end 12；Described its spiral shell of connecting tube 6 It is provided with the second snap ring 22 being integrated with itself outside stricture of vagina connection end.
