Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, this utility model provides a kind of technical scheme: the check valve that a kind of stability is strong, including shell 1,
One end of described shell 1 is provided with inlet attack 2, and the downside of described shell 1 one end is provided with outlet connection 3, described shell 1 other end
Middle part be provided with screw 12, the inner chamber of described shell 1 is provided with piston 5, and the side of described piston 5 is provided with leading screw 6 by bearing,
Described leading screw 6 is bolted in screw 12, and the end of described leading screw 6 extends to the outside of shell 1, and the side of described piston 5 is fixed
The first sleeve 8 being socketed on leading screw 6 is installed, on the right side of the inner chamber of described shell 1, is installed with the second set being socketed on leading screw 6
