Abstract
The utility model provides a switch handle of a combined type ball valve. The switch handle mainly comprises a handle body which is in a rhombus shape, a cylindrical protrusion is installed on the lower end face of the handle body which is installed unsymmetrically relative to the cylindrical protrusion, a pair of rectangular protrusions utilizing the cylindrical protrusion as the symmetrical center is installed on the upper end face of the handle body, and a pair of rectangular grooves different in size is installed inside the cylindrical protrusion. According to the switch handle of the combined type ball valve, the handle body is installed unsymmetrically relative to a rotating shaft of the handle, the arm of force of the switch handle is increased during rotation, and force required for opening and closing of the valve is reduced. The rectangular grooves are detachably matched with the valve to achieve opening and closing of the valve, the fact that the valve is difficult to open or close when the switch handle does not exist is ensured, and reliability of work of the valve is ensured. The pair of protrusions is installed on the upper end face of the handle body, a valve cover of the valve can be easily rotated through the protrusions, and convenience is brought to assembly and maintenance of the valve.
Description
Technical field
The utility model relates to a kind of handle, the switch knob of the combined type ball valve that especially a kind of and valve is used.
Background technique
Existing valve all is the switch gear of general shape, general valve all is exposed to outer, cause a lot of unrelated persons can both touch valve, in some cases, valve can appear by in the situation of misoperation or illegal operation, cause valve to be closed or open by improper, affect the work of whole system, economic loss.Simultaneously, when valve is installed, after spool is installed from a side of valve, need to limit with valve pocket the position of spool, because valve pocket is arranged on valve internal, can't handle be set at valve pocket, need to use specific tool switch, cause certain trouble.Existing valve is to the difficult realization of the control of the angle of unlatching in addition.
The model utility content
The purpose of this utility model is to provide a kind of to removably connect with valve for the deficiency that solves above-mentioned technology, and can make the switch handle of the more light labour-saving of the open and close combined type ball valve of valve.
In order to achieve the above object, the switch knob of the combined type ball valve that the utility model is designed, it mainly comprises handle body, handle body is diamond shape, is provided with cylindrical protrusions in its lower end surface, and handle body is take this cylindrical protrusions as asymmetric setting.This structural feature is increasing running torque, makes the open and close of valve more easily laborsaving, has also reduced simultaneously production cost.
As optimization, be provided with a pair of rectangular preiection take the cylindrical protrusions center as symmetry center in the upper-end surface of handle body, can cooperate with the inward recess on the valve pocket of valve, realize the rotation to valve pocket, make the easier for installation of valve pocket, simple.
Be provided with the different rectangular recess of a pair of size in cylindrical protrusions inside, realized that switch knob cooperates with the plug type of valve, when valve need to keep a state, can extract switch knob, avoid the personnel that have nothing to do to rotate unintentionally, affect the normal operation of valve.And can only determine that one cooperates direction, avoids making a mistake.
The switch knob of the resulting combined type ball valve of the utility model by the asymmetric setting of handle body with respect to the rotating shaft of handle, can increase the arm of force of switch knob when rotating, required strength when reducing valve switch.And detachably cooperate with valve by rectangular recess, realize the open and close of valve, guarantee simultaneously without this switch knob the time, valve will be difficult to open or close, and guarantee the reliability of valve working.Be provided with a pair of projection in the upper-end surface of handle body in addition, can utilize the easily valve gap of changeover valve of projection, made things convenient for assembling and the maintenance of valve.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, the switch knob of the combined type ball valve that present embodiment is described, it mainly comprises handle body 1, handle body 1 is diamond shape, be provided with cylindrical protrusions 2 in its lower end surface, and handle body 1 is provided with a pair of rectangular preiection 3 take cylindrical protrusions 2 centers as symmetry center take this cylindrical protrusions 2 as asymmetric setting in the upper-end surface of handle body 1.
Be provided with the different rectangular recess of a pair of size 4 in cylindrical protrusions 2 inside.
Claims (3)
1. the switch knob of a combined type ball valve, it mainly comprises handle body, it is characterized in that handle body is diamond shape, be provided with cylindrical protrusions in its lower end surface, and handle body is take this cylindrical protrusions as asymmetric setting.
