High ultra-vacuum special electric gate valve

Abstract

The invention discloses a high ultra-vacuum special electric gate valve, and relates to a valve. The valve comprises a valve body, an accessory plate, a connecting key, a first bolt, a main board, a connecting rod, a valve deck, an electric head, a gearbox, a driving key, a sleeve, and a transmission shaft. The valve body is internally provided with the accessory plate and the main board. The main board is provided with the connecting key and the first bolt. The accessory plate is provided with guiding grooves corresponding to the connecting key and the first bolt. The main board and the accessory plate are cooperated. The main board is provided with a first dedusting ring and a first seal ring. The accessory plate is provided with a second dedusting ring and a second seal ring. A middle contact surface of the main board and the accessory plate is a wedge surface. A compression spring is arranged between the main board and the accessory plate. The upper end of the main board is connected with the transmission shaft through the connecting rod. The transmission shaft is connected with the driving key which is in the gearbox in a transmission manner. The gearbox is connected with the electric head. The gate valve is long in service life, good in sealing effect, good in isolation vacuum effect, good in practicality, and easy in popularization and use.

Description

technical field [0001] The invention relates to a valve, in particular to a high-ultra-vacuum special electric plug-in valve. Background technique [0002] Special valves are widely used in military systems and equipment as well as high-end scientific research devices. Although the components are small, they play a huge role. They are key components that restrict the manufacturing of military equipment and the development of high-end scientific research devices in my country; High-vacuum valves are prone to wear and tear during actual use, resulting in a greatly reduced service life, and the sealing effect between the internal connection surfaces of the valve body is not good, which is prone to leakage problems, especially for unclean pipeline media. The valve body with commercial technology cannot guarantee high ultra-vacuum degree, which affects its use effect. Based on this, it is still necessary to design and develop a high-ultra-vacuum special electric gate valve. Conte...
