Embodiment Construction

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. And the features in the embodiments can be combined with each other.

[0020] The core of the present invention is to provide a high-seal plug-in valve for a vacuum spraying machine, which has good maintainability and sealing effect.

[0021] Such as Figure 1 to Figure 3 As shown, the high-seal plug-in valve for vacuum spraying machine of the present invention includes a valve seat 1 and a gate 2, and the gate 2 can be made of steel, and the surface is hard chrome plated or ion nitriding treatment to make the gate more wear-resistant , The service life of the sealing surface is enhanced. The valve seat 1 includes two parallel valve seat plates 11 and a fixed plate 12 fixedly connecting the two ends of the two valve seat p...

Abstract

The invention discloses a highly-sealed gate valve of a vacuum spray-coating machine, which comprises a valve seat (1) and a gate plate (2), wherein the valve seat comprises two parallel valve seat plates (11) and a fixing plate (12) for fixedly connecting two ends of the two valve seat plates through bolts; valve holes (3) are formed in the middle parts of the two valve seat plates; the gate plate is arranged between the two valve seat plates in a sliding manner; sealing rings (4) in sealing fit with the gate plate (2) are arranged at the peripheries of the valve holes of the two valve seat plates; the valve seat (1) is provided with a pressure cylinder (5) for driving the gate plate (2). The valve seat is composed of the two valve seat plates and the fixing plate for fixedly connecting the two valve seat plates through the bolts, so that the highly-sealed gate valve of the vacuum spray-coating machine is disassembled conveniently and has good maintainability; the valve seat is of a two-piece type structural design, so that the inner cavity has no clearance, and a medium is not easy to be clamped and blocked; in addition, the sealing rings in matching fit with the gate plate are arranged at the peripheries of the valve holes of the two valve seat plates, better sealing effects of double-sided soft sealing are achieved, and leakage rate is reduced greatly.

Description

technical field [0001] The invention relates to a feed processing machine, in particular to a high-seal plug-in valve for a vacuum spraying machine. Background technique [0002] At present, due to the working principle of the vertical vacuum spraying machine, the discharge valve must use a gate valve. The existing gate valves have complex structures, are difficult to disassemble, and have disadvantages such as poor sealing effect and poor maintainability, which lead to the stagnation of vertical vacuum spraying technology in China and no breakthrough. [0003] The purpose of the foregoing discussion is to introduce the reader to various aspects of the technology that may be related to various aspects of the present invention that will be described and / or claimed below. It is believed that the discussion will help provide background information for the reader to facilitate a better With the various aspects of the present invention in mind, it is therefore to be understood t...
