Embodiment Construction

[0020] The nuclear electric torpedo vacuum valve of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as Figure 1 to Figure 2 As shown, a nuclear electric torpedo vacuum valve according to the present invention comprises a valve body 5, a torpedo-shaped valve core 25 arranged in the valve body 5, and a lever assembly connected to the torpedo-shaped valve core 25 to drive the lever assembly A moving fork assembly and a driving device for driving the fork assembly to move. The driving device includes two sets of electric and manual driving devices, and the manual driving device is used as a backup for the electric device.

[0022] The upper end of the valve body 5 is fixed with a middle box body 6 by screws, and the upper end of the middle box body 6 is fixed with a driving mechanism box body 16 by screws. The rear end of the drive mechanism box body 16 is fixedly connected to the flange...

Abstract

The invention provides a nuclear electric torpedo vacuum valve, comprising a valve body, a torpedo-shaped valve core arranged in the valve body, a lever assembly for connecting the valve core, a fork assembly for driving the lever assembly to move, and a drive device for driving the fork assembly to actuate. The valve core consists of an arc-shaped enclosed disc and an arc-shaped tail cone connected with the enclosed disc; a corrugated pipe is arranged on a lever, a protective cover is covered outside the corrugated pipe; a fork can rotate around a support shaft; a roller is fixed on the upper end of the fork; and the drive device comprises a turbine shaft and a turbine for driving the turbine shaft to rotate. A spline on the turbine shaft are connected to a guide rail, a guide slot is arranged on the guide rail, the roller fixed on the upper end of the fork is embedded in the guide slot, a disc spring is sleeved on the turbine shaft, and a disc spring box with a compression disc spring is covered outside the disc spring. The electric torpedo vacuum valve is featured by simple structure, excellent sealing performance, fast responsiveness, and small action impact, meets the requirement on quick shutoff for nuclear safety, and can be operated manually or driven electrically.

Description

technical field [0001] The invention relates to a valve, in particular to a nuclear electric torpedo vacuum valve. Background technique [0002] The structural types of vacuum valves include pneumatic flapper valves, pneumatic flap valves, pneumatic butterfly valves, manual flapper valves, electromagnetic vacuum stop valves, diaphragm vacuum valves, ultra-high vacuum angle valves, high vacuum angle valves, and three-way ultra-high vacuum valves. Valves, fine-tuning vacuum valves, bellows vacuum stop valves, torpedo vacuum valves, rotary drum vacuum valves, jacketed Y-type vacuum stop valves, high vacuum fine-tuning vacuum valves, electromagnetic pneumatic vacuum valves, and diaphragm high-pressure high-vacuum valves. Nuclear vacuum valves include angle valves, torpedo valves, rotary drum valves, globe valves, etc. Nuclear torpedo vacuum valves are divided into electric and manual drive modes, and are in the form of flange connection. [0003] The Chinese patent "Electric T...
