Ball valve and gate valve belong to same class valve, and difference is that the closure member of ball valve is a spheroid, does to rotate the unlatching, the closedown that realize institute's adapter road around valve body center line by spheroid.Ball valve is mainly used to make the flow direction cutting off, distribute and change medium in pipeline.Tee ball valve is then a kind of novel ball valve, is divided into T-shaped and L-type, T-shapedly can make three orthogonal mutual UNICOMs of pipeline and cut off Article 3 passage, plays shunting, interflow acts on; L triple ball-type can only connect two mutually orthogonal pipelines, can not keep being interconnected of Article 3 pipeline simultaneously, only plays distributional effects.
Tee ball valve is widely used, and it has the following advantages: fluid resistance is little, and its resistance coefficient is equal with the pipeline section of same length; Structure is simple, volume is little, lightweight; Closely reliable, the seal face materials of ball valve widely uses plastics, good airproof performance, also widely uses in vacuum system; Easy to operate, opening and closing is rapid, if from standard-sized sheet to complete shut-down half-twist, be convenient to remote control; Easy to maintenance, ball-valve structure is simple, and seal ring is all generally movable, and dismounting and change is all more convenient; Applied widely, latus rectum is from little to several millimeter, large to several meters, all can apply from high vacuum to high pressure.
The reversing mode of common tee ball valve is handle wrench dynamic formula, and on the one hand, when flow and pressure increase, handle wrench braking torque obviously increases, and while labor intensity is larger, control accuracy is uncontrollable; The hydraulic system automatically controlled can not be adapted on the other hand, have a strong impact on the commutation efficiency of liquid stream; And the position of valve handle rotation when installing, will be left, limit its application area.
Summary of the invention
Commutate to make liquid stream and adapt to hydraulic control system, raising commutation efficiency, control accuracy, reduction labor intensity are not limited by working space restriction, the invention provides a kind of L-type tee ball valve of hydraulic control.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of hydraulic control three-way ball valve, comprise valve body, the ball seat be installed in valve body, be installed on spheroid on ball seat and with the spheroid rotating shaft be fixedly connected on spheroid, the cross section of spheroid rotating shaft is regular polygon, this hydraulic control three-way ball valve also comprises hydraulic control block, described hydraulic control block comprises gear, tooth bar, threaded mandrel, push rod and movable sheath, and the regular polygon hole that gear is arranged by Gear center place coordinates with spheroid rotating shaft; Wheel and rack coordinates, and tooth bar, threaded mandrel and push rod successively head and the tail are connected; Movable sheath is enclosed within outside and the threaded mandrel looping closed cavity of threaded mandrel, and second controls mouth and annular closed cavity connects; Push rod left end is provided with closed cavity, and first controls mouth is communicated with described closed cavity, and the section area of push rod left end is greater than the cross sectional area of annular closed cavity, and described second controls to maintain control liquid in mouth.
Further, positioning disk is provided with between described gear and spheroid rotating shaft.
Further, described gear exterior is provided with gear protective cover.
Further, the outside of described threaded mandrel and push rod is provided with piston protective cover.
Compared with prior art, beneficial effect of the present invention is:
Hydraulic control three-way ball valve of the present invention replaces traditional handle to drive the commutation realizing liquid stream by hydraulic control block, Automatic hydraulic control system can well be applicable to, and make the use of tee ball valve no longer be limited by working space, improve commutation efficiency and the applicability of tee ball valve, reduce labor intensity;
The hydraulic control block structure of hydraulic control three-way ball valve of the present invention is simple, easy to operate, easy to utilize.
