Abstract
The utility model discloses a blind plate isolating valve body structure. The structure comprises a first fixed valve body, a second fixed valve body and a moving valve body, wherein the first fixed valve body and the second fixed valve body are fixed on two sides of a U-shaped support, the moving valve body is connected with the first fixed valve body through a compensator, a load bearing support of the moving valve body is connected with a guide sleeve, the guide sleeve is movably connected with a slide bar arranged at the top of the U-shaped support, a gear ring is movably connected onto the first fixed valve body and in transmission connection with a power device, the gear ring is in meshed transmission with a first gear and a second gear respectively, the first gear and the second gear are concentrically fixed with lead screws respectively, and the lead screws are in transmission with the U-shaped support and the load bearing support respectively. According to the structure, the large gear ring is used for driving the small gears with same specifications, and then the lead screws concentrically fixed with the small gears are in transmission with the moving valve body, so that the moving valve body is evenly stressed, opening and closing processes of a valve are stable, and the service life of the valve is effectively prolonged.
Description
Technical field
The utility model relates to machinery manufacturing technology field, is specifically related to a kind of valve.
Background technique
Along with carrying out of energy-saving and cost-reducing work, increasing enterprise is used coal gas as fuel, but coal gas has toxicity, inflammable and explosive feature, when maintenance gas pipe line, need SC, blind plate isolating valve as one be swift in motion, easy to operate, cut off gas performance cocksure valve, be widely used in gas pipe line.The valve body of the blind plate isolating valve that prior art is manufactured, carries out transmission by push rod between its mobile valve and main valve body, makes mobile valve discontinuity, long-term use easily causes mobile valve torsional deformation, affect the sealing of valve, form potential safety hazard, even cause industrial accident.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of blind plate isolating valve valve body structure, can solve the problem that mobile valve of the prior art easily causes mobile valve torsional deformation with push rod transmission so that affects sealability.
The utility model is achieved through the following technical solutions:
A kind of blind plate isolating valve valve body structure, comprise the first fixed valve body and the second fixed valve body that are fixed on U-shaped support both sides, and the mobile valve being connected with the first fixed valve body by compensator, the support bracket of described mobile valve is connected with guide sleeve, described guide sleeve is flexibly connected with the slide bar that is arranged on U-shaped top of the trellis, on described the first fixed valve body, be connected with gear ring, described gear ring and power plant are in transmission connection, described gear ring respectively with the first gear, the second meshed transmission gear, described the first gear and the second gear are fixed with respectively leading screw with one heart, described leading screw respectively with U-shaped support and support bracket transmission.
Further improvement of the utility model scheme is that gear ring and the first fixed valve body are Spielpassung, on described the first fixed valve body, are provided with limiting stopper in gear ring both sides.
Further improvement of the utility model scheme is that the first gear is identical with the second gear set specifications.
Further improvement of the utility model scheme is that power plant are oil hydraulic pump or pneumatic cylinder or motor.
The utility model advantage is compared with prior art:
Adopt bull gear to drive the small gear of same size, then, with the concentric fixing leading screw of small gear and mobile valve transmission, make mobile valve uniform stressed, the opening-closing process of valve is steady, effectively extends the working life of valve.
