Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an open-type push-pull valve, include support 1 and install two valve bodies 2 and the valve body 2 on support 1 between have flashboard 3, it is very ripe among the power unit prior art of flashboard 3, do not do any repeated description here, the end fixing cover that valve body 2 is close to flashboard 3 is equipped with sealing ring 4, fixed cover is equipped with solid fixed ring 5 and sealing ring 4 and solid fixed ring 5 on the valve body 2 between the cover is equipped with disk seat 7 that slides at valve body 2, it is connected with a plurality of member 6 and member 6 runs through solid fixed ring 5 to rotate on the disk seat 7, the end of member 6 has the integral key shaft and inserts and establish in the output shaft sleeve 12 on fixing the speed reducer 13 on the lateral wall of valve body 2, speed reducer.
