Valve is the crucial controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Existing valve mechanism, its structural representation as shown in Figure 1.Drive valve plate by the handwheel rotation and move up and down, realize closing or opening of valve like this.But, such valve, handwheel is connected by thread engagement with valve rod, in switching manipulation, handwheel is skidded, and is difficult for switching manipulation.
The model utility content
The deficiency that the utility model exists at prior art just provides a kind of valve for guarding against theft of being convenient to switch.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of valve of being convenient to switch comprises valve rod and handwheel, and the top end face of described valve rod is provided with groove; Described handwheel center is provided with elongated center-pole, and the sectional shape of center-pole is identical with the groove sectional shape of valve stem tip end face, and center-pole inserts in the groove of valve rod.
Further, the sectional shape of described valve stem tip end face groove is an equilateral triangle.
Further, the sectional shape of described valve stem tip end face groove is a square.
Further, the sectional shape of described valve stem tip end face groove is a regular hexagon.
The utility model compared with prior art, implementation result of the present utility model is as follows:
The valve of being convenient to switch described in the utility model utilizes the handwheel center-pole of given shape to cooperate with valve rod, has realized valve opening and has closed, and has prevented that effectively the phenomenon that occurs skidding when rotation hand wheel from taking place.

Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
See also Fig. 1, Fig. 1 is an existing valve mechanism schematic representation described in the background technique.
Existing valve comprises valve body 1, valve gap 2, valve plate 3, valve rod 4, valve plate seal ring 5, gland 6, handwheel 7 and valve seals 8.The inside of valve body 1 is provided with bigger cavity, and there is unlimited opening at two ends, is convenient to entering and flowing out of fluid like this.Valve gap 2 is installed in the top of valve body 1, and valve gap 2 inside are provided with certain cavity, and the cavity of this cavity and valve body 1 inside mates mutually.Be provided with valve seals 8 between valve gap 2 and the valve body 1,, utilize the locking nut (not shown) that the three tightly is locked together in case fluid is revealed.The oral area of valve gap 2 upper ends is less, and the oral area inboard is provided with internal thread.
Bigger cavity central position at valve body 1 is equipped with valve plate 3, between the both sides of valve plate 3 and the valve body 1 valve plate seal ring 5 is installed, and valve plate 3 is flat tabular, and its size is bigger slightly than the cavity in the valve body 1, just in time can stop fluid to flow in valve body 1.Valve rod 4 is installed directly over the valve plate 3, and valve rod 4 is provided with outside thread.Valve rod 4 passes the oral area of valve gap 2 upper ends, and the internal thread of outside thread on the valve rod 4 and valve gap 2 oral areas is meshing with each other.
Be provided with gland 6 in valve gap 2 upper ends, gland 6 neutral positions are provided with center hole, gland 6 and valve gap 2 screw-threaded couplings.Gland 6 upper ends are provided with handwheel 7, and handwheel 7 centers are provided with elongated center-pole 7a, and center-pole 7a passes the center hole of gland 6, are connected and fixed with valve rod 4.
When rotation hand wheel 7, center-pole 7a drives valve rod 4 rotations, and under valve gap 2 oral area screw-thread fit, valve rod 4 rotations also move up and down, and drive moving up and down of valve plate 3 by moving up and down of valve rod 4 like this, finally realize the open and close of valve.
See also Fig. 2 and Fig. 3, wherein Fig. 2 is convenient to the structural representation of the valve of switch for the utility model; Fig. 3 is the plan view of Fig. 2.
The valve of being convenient to switch described in the utility model is to improve on existing valve mechanism basis, and it improves component and comprises: valve rod 4 ' and handwheel 7 '.
Valve rod 4 described in the utility model ' the top end face be provided with groove 4 ' a, groove 4 ' a shape has certain requirement, groove 4 ' a sectional shape is a kind of in equilateral triangle or square or the regular hexagon.
See also Fig. 4 and Fig. 5, wherein Fig. 4 is a handwheel structural representation of being convenient to the valve of switch described in the utility model; Fig. 5 is an A-A view among Fig. 4.
Described handwheel 7 ' center is provided with elongated center-pole 7 ' a, the sectional shape of center-pole 7 ' a is identical with groove 4 ' a sectional shape of valve rod 4 ' top end face, and center-pole 7 ' a inserts among valve rod 4 ' groove 4 ' a, by handwheel 7 ' on center-pole 7 ' a rotation, drive valve rod 4 ' rotation.
When not needing to adjust valve state, draw off handwheel 7 ', gland 6 ' upper end is exposed in the open air, rainwater, dirt etc. easily stop up gland 6 ', by sewage draining exit 6 ' a, can suitably discharge rainwater, dirt etc. like this.Draw off handwheel 7 ' after, stopped like this to handwheel 7 ' misoperation, simultaneously also avoided handwheel 7 ' lose.When needs are adjusted valve state, can install easily handwheel 7 ', handwheel 7 ' on center-pole 7 ' a and the groove 4 ' a of valve rod 4 ' top end face cooperatively interact, like this rotation hand wheel 7 ', drive valve rod 4 ' rotation, effectively prevented the generation of the skidding of handwheel 7 ' in rotary course.
Above content is the detailed description of the utility model being done in conjunction with concrete preferred implementation, can not assert that the concrete enforcement of the utility model only limits to these explanations.For the utility model person of ordinary skill in the field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to the scope of the utility model protection.
