In order to overcome above-mentioned technical problem, the utility model provides a kind of leakage resistant valve.
Leakproof valve of the present utility model, comprises valve body, control valve body; Be provided with control valve body groove in the middle of described valve body, described control valve body groove upper and lower end is respectively arranged with twisting entablature, a platform groove, and described control valve body is arranged in described control valve body groove; Described control valve body is square cylinder and offered the mouth of a river in the middle part of it, described control valve body upper end is provided with twisting platform, described twisting platform upper end is square column, described control valve body lower end is also provided with and rotates platform, and described twisting platform, to rotate a platform corresponding with the twisting entablature on described control valve cell body, a platform groove respectively; The upper and lower two ends of described control valve body are all fixedly installed stuffing box gland, described valve body two ends are also provided with anti-fistulae, described anti-fistulae leading portion is tapered opening and offers outside thread outside body, described valve body two ends are provided with internal thread, and described anti-fistulae is fixedly installed on described valve body both sides by described outside thread, internal thread.
Further, described anti-fistulae is nitrile butadiene rubber material.
Further, described stuffing box gland is nitrile butadiene rubber material.
Further, described rotation Zhi Taiwei hemisphere props up platform.
Further, the described mouth of a river of crossing is that ellipse crosses the mouth of a river.
Wherein:
Be provided with control valve body groove in the middle of described valve body, described control valve body groove upper and lower end is respectively arranged with twisting entablature, a platform groove, and described control valve body is arranged in described control valve body groove; Described control valve body is square cylinder and offered the mouth of a river in the middle part of it, described control valve body upper end is provided with twisting platform, described twisting platform upper end is square column, described control valve body lower end is also provided with and rotates platform, and described twisting platform, to rotate a platform corresponding with the twisting entablature on described control valve cell body, a platform groove respectively; Such setting, makes described control valve body better process, and impacts when can not twist control valve body;
The upper and lower two ends of described control valve body are all fixedly installed stuffing box gland, and such is arranged so that valve body can not be revealed;
Described valve body two ends are also provided with anti-fistulae, described anti-fistulae leading portion is tapered opening and offers outside thread outside body, described valve body two ends are provided with internal thread, described anti-fistulae is fixedly installed on described valve body both sides by described outside thread, internal thread, after such setting makes leakproof valve access conduit of the present utility model, a leak-proof measure inherently can be provided, and offer in the pipeline of device the sloping platform corresponding with the taper platform on described anti-fistulae can not with described pipeline on be wound around leakage preventing tape or sealer situation under realize leakproof.
Leakproof valve of the present utility model, structure is simple, easy to make, with low cost; Adopt and anti-fistulae is set on its valve body enters the easier cost of production of installation that Novel control valve body makes to cut down and greatly reduce.
