Abstract
The utility model relates to a kind of valve, especially a kind of low leakage sealed fixing ball valve.Low leakage packing seal structure comprises packing cavity, dish spring, filler, dish spring chamber, Gland, and filler is arranged in packing cavity, and Gland is arranged on packing cavity, pushes down filler, and dish spring is arranged in dish spring chamber, and withstands Gland.Said structure is external by locating stud, be fixedly connected with land, in assembling, just need not hole so, installation and removal easily, be provided with a low leakage packing seal structure being formed by packing cavity, dish spring, filler, dish spring chamber, Gland simultaneously, even if seal ring is damaged, effect due to Gland and dish spring, filler can not revealed, even if there is part to enter valve inner, can control discharge by blowdown valve, blowdown chamber and blowdown valve, for discharging impurity and the internal leakage thing in valve body, extend working life of the present utility model.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of low leakage sealed fixing ball valve.
Background technique
Ball valve is a kind of spheroid open-shut device, by valve rod, driven, and the valve rotating around the axis of valve rod.Be mainly used in blocking or connecting the medium in pipeline, also can be used for adjusting and the control of fluid, wherein firmly seal between its V-type ball core of V-type ball valve and the metal seat valve of pile-up welding hard alloy and there is very strong shearing force, be specially adapted to the media such as fibre-bearing, small solid particle.And multi-pass ball valve not only switching of the interflow of control media, shunting and the flow direction flexibly on pipeline, the while also can be closed arbitrary passage and two other passage is connected, and ball valve generally should level be installed in pipeline.Ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
Current large-scale ball valve is that valve mechanism is first assembled, then join brill, and locating stud is joined brill together with several parts, drilling machine, in processing, can produce iron filings and enter boring or valve internal, and will coordinate large-scale boom hoisting in processing, installation or removal trouble very, and after Sealing corresponding to filler of the prior art damage, fire-proof packing will leak, some danger medium even can cause serious environmental pollution.
Model utility content
The purpose of this utility model is, the low leakage sealed fixing ball valve of a kind of low leakage, compact structure, easy installation and removal is provided.
The utility model solves the technological scheme that further technical problem adopts: a kind of low leakage sealed fixing ball valve, comprise valve body, valve gap, valve rod, spheroid, valve rod and spheroid are arranged in valve body, valve gap is arranged on valve body, also comprise low leakage packing seal structure, low leakage packing seal structure comprises packing cavity, dish spring, filler, dish spring chamber, Gland, filler is arranged in packing cavity, Gland is arranged on packing cavity, push down filler, dish spring is arranged in dish spring chamber, and withstands Gland.
Of the present utility modelly further be set to: also comprise land, locating stud, locating stud is welded on valve gap, and is fixedly connected with land, and packing cavity is arranged on valve gap, and land is fixedly installed on valve gap, and form dish spring chamber with valve gap.
Of the present utility modelly further be set to: also comprise blowdown chamber, in valve body bottom, offer a groove, corresponding bottom groove and spheroid, as blowdown chamber.
Of the present utility modelly further be set to: also comprise that blowdown valve, blowdown valve are arranged on the bottom in blowdown chamber, and lead to valve body outside.
Said structure is external by locating stud, be fixedly connected with land, in assembling, just need not hole so, installation and removal easily, be provided with a low leakage packing seal structure being formed by packing cavity, dish spring, filler, dish spring chamber, Gland simultaneously, even if seal ring is damaged, effect due to Gland and dish spring, filler can not revealed, even if there is part to enter valve inner, can control discharge by blowdown valve, blowdown chamber and blowdown valve, for discharging impurity and the internal leakage thing in valve body, extend working life of the present utility model.
