The aperture position of described two airtubes is equipped with an O-ring seals;
The connecting passage be connected with airtube front end is also provided with in described female main body;
The shape of described connecting passage and described male body front end is suitable, is provided with two O-ring seals in connecting passage, and this O-ring seals contacts with the outer wall for male main body and coordinates;
Described two airtubes include the straight way that the cone Dao Heyuzhui road that is connected with opening is connected;
All be installed on a spool by guiding element, spring in described two airtubes, the opening in Dao Suo road is stretched out in the front end of spool;
Described guiding element coordinates with the C type jump ring be installed in airtube;
Described spool comprises valve rod, valve head, and valve head and valve rod are connected as a single entity;
Described valve head comprises rear, stage casing, leading portion, and the size of rear, stage casing, leading portion diminishes successively, and two adjacent two intersegmental connection transitional surfaces are inclined-plane;
The connection transitional surface in described rear and stage casing is provided with an O-ring seals, and this O-ring seals is used for contacting with the taper wall in airtube Zhong Zhui road coordinating;
The stage casing of described valve head coordinates with establishing to contact with the O-ring seals on the aperture position of airtube;
Size and the airtube of the rear of described valve head are suitable, have some gas guide grooves vertically in this rear side.
When the present invention works, off state and coupled condition is divided between male main body, female main body, when being in off state, the valve head of male main body, female main body valve body is depressed by the top of spring and is utilized the O-ring seals of the O-ring seals on valve head and airtube opening to be sealed by airtube opening, realizes secondary seal.
When being in coupled condition, male main body, female main body fixed are integrated by outer shroud, two O-ring seals in connecting passage are utilized to be sealed by connecting passage, realize the secondary seal of connecting passage, meanwhile, the valve head of two valve bodies is conflicted and is coordinated, and makes the equal Compress Spring of two valve bodies and return, remove the sealing state of airtube opening, utilize the gas guide groove on valve head tail end to make two airtube conductings.
Structure of the present invention is simple, reasonable in design, no matter be secondary seal in off state and coupled condition between male main body, female main body, makes the use of storing up ammonia tank safer.
