Description
Technical field
The utility model relates to the structure of ball valve, is applicable to the occasion needing tightly to prevent from leaking outside, as hypertoxic hazardous medium, involve great expense medium and other do not allow the operating mode etc. of leaking.
Background technique
Ordinary ball valve mainly comprises valve body, valve gap, stuffing box, spheroid, valve rod, valve gap is connected by the first bolt with valve body, stuffing box is connected to the neck of valve body by the second bolt, spheroid is arranged between valve body and valve gap, first valve seat is set between spheroid and valve body, arrange the second valve seat between spheroid and valve gap, one end of valve rod is fixedly connected with spheroid, the other end stretches out valve body and connecting handle after stuffing box.Existing handle is common iron sheet punching press integral type, can not ensure the exact position of ball valve open-close on-off.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of handle strip to locate the ball valve with lock function, can guarantee the exact position of ball valve open-close on-off.
The purpose of this utility model is achieved in that the ball valve of handle strip location and lock function, comprise valve body, valve gap, stuffing box, spheroid, valve rod, valve gap is connected with valve body, stuffing box is connected to the neck of valve body, spheroid is arranged between valve body and valve gap, first valve seat is set between spheroid and valve body, second valve seat is set between spheroid and valve gap, one end of valve rod is fixedly connected with spheroid, the other end stretches out connecting handle after valve body and stuffing box, described handle comprises handle body and clamping disk(-sc), one end of handle body is welded with clamping disk(-sc), clamping disk(-sc) is clamped in the upper end of valve rod by the second bolt, threaded stem attaching nut above clamping disk(-sc), positioning disk is connected by thread screw in the upper-end surface of described stuffing box, positioning disk is arranged on the below of clamping disk(-sc), positioning disk is arranged initial point positioning hole and terminal positioning hole, described clamping disk(-sc) arranges locating stud, locating stud is detachable to be plugged in initial point positioning hole and terminal positioning hole.
The utility model is by above design, positioning disk has been installed by screw in stuffing box upper-end surface, positioning disk is offered positioning hole, locating stud is installed on handle clamping disk(-sc), after handle rotate in place, locating stud can insert in the positioning hole of initial point and terminal, and band ovable valve stem, ball valve rotate, realize the opening and closing of ball valve, and the exact position of ball valve open-close on-off can be guaranteed.
As improvement of the present utility model, on locating stud between clamping disk(-sc) and positioning disk, radial direction arranges through hole, mechanical spring lock is set in through hole, there is mechanical spring latch at aperture place on locating stud, locating stud is made not transfer to positioning hole, avoid misoperation valve like this, realize the safe and reliable operation of process system.
As further improvement of the utility model, arrange spacing breach, positioning disk connects positioning screwn in the lower end surface of described clamping disk(-sc), positioning screwn is arranged in spacing breach.Positioning screwn can make handle rotate within the limits prescribed with coordinating of spacing breach.When handle rotates, rely on positioning screwn restriction to rotate initial point and terminal, ensure the exact position of ball valve open-close on-off.
