Specific implementation mode
The embodiments of the present invention are described further below for attached drawing：
A kind of Pull breaking ualve, including upper valve body 1, lower valve body 2 and spool 3, the upper valve body 1 and lower valve body 2 match, institute
It states spool 3 to be located in upper valve body 1 and lower valve body 2, the upper valve body 1 is equipped with positioned at the outer positioning region 4 of lower end, the lower valve body
2 are equipped with positioned at the interior positioning region 5 of upper end, and the lower valve body 2 is inserted in upper valve body 1 and the interior positioning region 5 and outer positioning region 4
It is corresponding, retaining structure is equipped between the outer positioning region 4 and interior positioning region 5, the retaining structure includes that snap ring 6, first blocks
Slot 7 and the second card slot 8, first card slot 7 are located on the inner wall of the outer positioning region 4, and second card slot 8 is located at described
On the outer wall of interior positioning region 5, second card slot 8 is v-shaped structure, includes being rolled positioned at the screens portion 81 of bottom and positioned at two
