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: exquisite type discharge valve, including valve body 1, connector 101 on the 1 bottom of valve body, the floater 9, and valve gap 2 on the 1 top of valve body through 3 fixed connection of bolt, connector two 201 has on the valve gap 2, and it is connected with the cap 5 to close on connector two 201, connector two 201 and valve body 1's inside intercommunication, the gas pocket 501 of the form of bending has been seted up on the cap 5, can make valve exhaust efficiency improve under the cap 5 dismantlement, connector two 201 bottoms have and close the disk seat 4 of connection on valve gap 2 soon, the lateral wall fixedly connected with engaging lug 6 of disk seat 4, and it has lever 7 to articulate on the engaging lug 6, fixedly connected with inserts the chock plug 8 of establishing in disk seat 4 on the lever 7.

Specifically, as shown in fig. 3, the plug 8 has a conical head portion 803 inserted inside the lever 7, the conical head portion 803 is connected with a gasket portion 802 and a ball head portion 801 which are integrally formed, the ball head portion 801 is inserted inside the valve seat 4, the plug 8 is equivalent to a valve flap and is used for opening and closing the valve, and under the pressure of a medium, the plug 8 better closes the valve to prevent the leakage of the medium.

Specifically, as shown in fig. 3, the valve seat 4 communicates with the cap head 5, and the opening at the bottom end of the valve seat 4 is provided with a chamfer portion 401, and the arrangement of the chamfer portion 401 slows down the abrasion of the plug head 8.
