Low-temperature stop valve

Abstract

The invention discloses a low-temperature stop valve, and belongs to the field of stop valves, according to the scheme, in a low-temperature environment, heat is released through a two-way adjusting ball in a temperature change adjusting mechanism to conduct cold and heat alternation, the low-temperature influence is reduced, a valve clack body is not prone to being frozen, damage is reduced, and meanwhile when fluid impacts the valve clack body, a vibration transmission mechanism can transmit vibration to the valve clack body. The material storage capsule is driven by the transmission rod to swing, dissipation of heat in the material storage capsule is accelerated, air flowing in the valve clack body is accelerated through swinging of the swinging blades, the cold and heat alternating effect is enhanced, flowing impact is transmitted to the connecting base, collision small balls move and rub with one another, static electricity is generated, and an adsorption moving plate drives a magnetic insulation cover and a magnetic insulation movable piece to be separated. The magnetic refrigeration block releases heat under the action of the magnet piece, the movable plate is attracted to move to drive air to flow, the heat is rapidly dispersed to all directions, the valve clack body is heated, the valve clack body is not prone to being affected in the low-temperature environment, and the using effect and the protection effect of the valve clack body are enhanced.

Description

technical field [0001] The present invention relates to the field of shut-off valves, and more particularly, to a low-temperature shut-off valve. Background technique [0002] Globe valve, also known as cut-off valve, is a mandatory sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to not leak. The opening and closing parts of the globe valve are plug-shaped discs, and the sealing surface is flat Or sea cone surface, the valve disc moves linearly along the center line of the valve seat, which can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Often used as cut-off or adjustment and throttling. [0003] When the globe valve is used in a low temperature environment or used in a low temperature environment, the valve disc is affected by the environment and is easily frozen, so that the normal opening and clo...

Problems solved by technology

[0003] When the globe valve is used in a low-temperature environment or used in a low-temperature environment, the valve disc is affected by the environment and is easily frozen, which affects the normal opening and closing of the valve disc, which is not conducive to use. At the same time, it is easy to cause damage to the valve disc and shorten its life. service life
