Abstract
The invention relates to a fireproofing vacuum heat-insulating ball valve which comprises a valve body, a ball body, a fireproofing table, a heat insulating medium, a jacket outer layer, anti-static steel balls, anti-static springs and the like. A seal seat adopts a metal-to-metal fireproofing convex table arrangement structure, and the fireproofing table and the valve body are integrated so as to ensure fire burning and effective sealing; the head part of a valve rod is provided with two holes, and the anti-static spring and the anti-static steel ball are installed in each hole. An anti-static device is made by connecting the anti-static steel balls with the anti-static springs, so that the production of friction static electricity on the ball body is prevented, and stable and safe conduction is achieved. The jacket outer layer is welded outside the valve body, a cavity space is formed between the jacket outer layer and a case outer surface, and an integral heat-insulating construction is made to reduce heat dissipating area. The jacket outer layer is connected with two one-way valves, and a jacket for heat insulation is filled with a perlite heat-insulating material and is vacuumized so as to avoid the heat conduction of air. The ball valve insulates heat during operation, the medium can not be solidified due to temperature reduction, the operation is convenient, and the service life is prolonged.
Description
Technical field:
The present invention relates to a kind of fire prevention ball valve, be specifically related to a kind of fire prevention vacuum heat-preserving ball valve, its insulation is adopted chuck filling pearlife thermoinsulation material and is vacuumized, and avoids air heat conduction, has prolonged working life.
Background technique:
Traditional ball valve does not have the insulating structure of design specialized, and when medium passed through inner chamber, the medium that easily solidifies can solidify in Yin Wendu decline, formation torsion is big, and sealing surface easily is worn, and causes leakage to produce static and catches fire, working life is short, results in hand cramps or safety problem to the user.
Summary of the invention:
Deficiency at existing fire prevention ball valve the invention provides a kind of fire prevention vacuum heat-preserving ball valve, is made up of valve body, spheroid, fire prevention platform, adiabatic medium, chuck skin, antistatic steel ball, antistatic spring etc.
The technical solution adopted for the present invention to solve the technical problems is: sealing seat is made with the fire prevention boss of metal to metal, the structure of fire prevention platform and valve body one, the valve rod head has two holes, static spring and static steel ball are housed in each hole, and anti-static device is connected with the antistatic spring with the antistatic steel ball to be made.Valve body external welding chuck skin, chuck is outer to form a cavity space with the housing appearance, makes the integral heat preservation structure, is connected to two one-way valves on the chuck shell, and insulation is filled the pearlife thermoinsulation material and is evacuated with chuck and makes.
The invention has the beneficial effects as follows: the insulation that is in operation, medium can Yin Wendu descend and solidify, and easy to operate, fire prevention, antistatic increase the service life.
