Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution:
the utility model provides a run-in double gate board gate valve, includes valve body 1, disk seat 2, disk seat sealing washer 3, controls flashboard 4, cylindrical spring 5, flashboard frame 6, wedge 7 and valve rod 8, and the 1 inboard bottom left and right sides of valve body all is equipped with disk seat 2, and disk seat 2 with control flashboard 4 in close contact with, 6 top fixedly connected with valve rods 8 of flashboard frame, and valve rod 8 and 1 sliding connection of valve body.
One side of the end part of a left flashboard 4 and a right flashboard 4 is provided with a cylindrical spiral blind hole, a cylindrical spring 5 is fixedly connected with the left flashboard 4 and the right flashboard 4, the cylindrical spring 5 penetrates through a flashboard frame 6 and a wedge block 7, the flashboard frame 6 and the wedge block 7 are tightly connected together through the cylindrical spring 5, the flashboard frame 6 and the wedge block 7 are both positioned at the inner side of a valve body 1, the arrangement facilitates the assembly of an inner valve core of the device, one end of a valve seat 2, which is far away from the vertical central line of the valve body 1, is provided with a valve seat sealing ring 3, the valve seat sealing ring 3 is contacted with the valve body 1, the arrangement ensures the sealing performance after the installation of the valve seat 2, the valve seat sealing ring 3 is made of a plate material, the valve seat sealing ring 3 is distributed at the edge of the outer side of the valve seat 2, the arrangement ensures the sealing performance after the installation of the valve seat 2 is better, the outer side of the flashboard frame 6 is provided with a boss which is connected with the left flashboard 4 in a sliding way, this arrangement facilitates control of the left and right shutter plates 4 for up-and-down movement, thereby facilitating control of opening and closing of the apparatus.
