For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of hydraulic control tee ball valve, comprise valve body, be installed on ball seat in valve body, be installed on spheroid on ball seat and with the spheroid rotating shaft being fixedly connected on spheroid, the cross section of spheroid rotating shaft is regular polygon, this hydraulic control tee ball valve also comprises hydraulic control piece, described hydraulic control piece comprises gear, tooth bar, threaded mandrel, push rod and movable sheath, and the regular polygon hole that gear arranges 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 is communicated with annular closed cavity; 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, in described the second control mouth, maintains control liquid.
Further, between described gear and spheroid rotating shaft, be provided with positioning disk.
Further, described gear outside 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 tee ball valve of the present invention replaces traditional handle to drive to realize the commutation of liquid stream by hydraulic control piece, can well be applicable to hydraulic pressure automatic control system, and make the use of tee ball valve no longer be limited by working space, improved tee ball valve commutation efficiency and applicability, reduced labor intensity;
The hydraulic control block structure of hydraulic control tee ball valve of the present invention is simple, easy to operate, easy to utilize.
