Embodiment Construction

[0027] like figure 1 and figure 2 As shown, the valve core assembly 1 includes a valve plate (lower valve plate) 11 , a support plate (upper valve plate) 12 , a steel ball 13 , a spring plate 14 and a steel ball holder 17 . The steel ball frame 17 is circular and has a plurality of ball holes 171 in the circumferential direction. Two steel balls 13 are placed in each ball hole 171. The steel ball 13 above protrudes from the upper edge of the ball hole 171 and supports The lower surface of the plate 12 is in contact, and the lower edge of the steel ball 13 protruding from the ball hole 171 is in contact with the upper surface of the valve plate 11, as figure 1 In the shown embodiment, there are altogether 12 nanoball holes in the steel ball frame 17 . The steel ball frame 17 is fixedly clamped by two groups of spring plates 14, and each group of spring plates 14 comprises an upper spring plate 141 positioned at the upper side of the steel ball frame 17, a lower spring plate ...

Abstract

The invention relates to a swinging water-cooled vacuum gate valve and a spool component thereof. The valve and the spool component can be higher in sealing performance. The spool component comprises a support plate, a valve plate and a ball rack. A rotary steel ball is disposed on the ball rack. The steel ball is rested between the support plate and the valve plate and is held by the spring plate. A spring plate on the support plate side of the ball rack is connected with the support plate. Another spring plate on the valve plate side of the ball rack is connected with the valve plate. The valve plate and the support plate are opened by the steel ball, and accordingly pressure is applied to the valve plate. An upper cover plate and a lower cover plate are provided with ball pits corresponding to the steel ball. The steel ball can be fitted in the ball pits, so that the pressure of the steel ball upon the valve plate is released. The swinging water-cooled vacuum gate valve is available for full water cooling, so that the service life of a seal ring is prolonged.

Description

technical field [0001] This invention relates to valves used in vacuum systems, and more particularly to gate valves. Background technique [0002] At present, manufacturers of single crystal and polycrystalline furnaces use manual water-cooled isolation valves, which have large longitudinal dimensions, short service life of "O"-shaped sealing rings, poor sealing performance, unstable work, and cannot be automatically controlled. Therefore, manufacturers of single crystal and polycrystalline furnaces urgently need to be able to work at a temperature of 1450 ° C. The "O"-shaped sealing ring can be protected by water cooling from being scorched, melted, and aged, so that the single crystal and polycrystalline furnaces can work efficiently. , Large production capacity, automatic control valves can be implemented. Contents of the invention [0003] The object of the present invention is to provide a swing-type water-cooled vacuum slide valve to improve the sealing performance...
