Abstract
The utility model relates to a valve handle and a spanner of the valve handle, and belongs to the technical field of mechanical structures, wherein the spanner is used for opening and closing a valve. The valve handle is characterized in that a valve handle body is in a circular-ring-body shape, gear teeth (1) which are distributed at equal internals in a whole row mode are arranged on the periphery of the valve handle body, and a notch is formed between every two adjacent gear teeth; the extension lines of the side edges of the gear teeth (1) are connected in the center of the valve handle; the spanner (2) is provided with two spanner teeth (201) corresponding to the notches, and the spanner teeth (201) are inserted into the notches; when the spanner is rotated, the valve handle is rotated. The valve handle solves the technical problem that a valve handle in the prior art is arduous in rotation. The valve handle is simple in structure and easy to manufacture and machine. The structure of the spanner which is matched with the valve handle is provided, and using is very convenient.
Description
Technical field
The utility model relates to a kind of valve handle and spanner thereof, is used for the open and close of valve, belongs to the mechanical structure technical field.
Background technique
Valve is the controlling component in the fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.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.
Adopt manual form to come the valve of opening and closing, generally all can be provided with handwheel, handwheel is round structure, and its principle is to utilize the handwheel radius as the arm of force, strengthens driving torque, and under the therefore equal torsion, the handwheel radius is larger, and moment of torsion is larger.
Existing handwheel, its circumference is generally smooth curve, comprises that perhaps some increase the moulding of frictional force, and still, when valve is tighter, in the situation about need to rotate than high pulling torque, free-hand rotation is effort very often, causes operator's labor intensity larger.
Summary of the invention
The utility model technical issues that need to address are: existing handwheel, its circumference is generally smooth curve, comprise that perhaps some increase the moulding of frictional force, but, when valve tighter, in the situation about need to rotate than high pulling torque, free-hand rotation is effort very often, causes operator's labor intensity larger.
The utility model is taked following technological scheme:
A kind of valve handle, described valve handle main body is the annulus bodily form, and its periphery is provided with the gear teeth 1 that equidistant permutation distributes, and contains recess between the described gear teeth and the gear teeth.
The elongation line of the described gear teeth 1 side is intersected in the center of described valve handle.Be convenient to processing.
The tooth depth of the described gear teeth 1 is 20-100mm.
Described spanner 2 is provided with two pulling teeth 201, and described pulling teeth 201 is corresponding with described recess, and pulling teeth 201 inserts in the described recess, and rotary spanner rotates described valve handle.
Characteristics of the present utility model are: the technical problem of effort when rotating for valve handle in the prior art, a kind of handwheel with the well-regulated gear teeth is provided, by corresponding with it spanner, the pulling teeth of spanner and the outer rim of handwheel form engagement, provide rotating power to handwheel again.
The beneficial effects of the utility model are:
1) solved the technical problem that the rotation of prior art valve handle is required great effort.
2) provide simple in structure, made the valve handle structure of easy processing.
3) provide the structure of corresponding supporting spanner with valve handle, used very convenient.
Description of drawings
Fig. 1 is the structural representation of the valve handle of prior art.
Fig. 2 is the plan structure schematic representation of the utility model valve handle.
Fig. 3 is the main TV structure schematic representation of the utility model valve handle.
Fig. 4 is the structural representation of spanner of the present utility model.
Wherein, 1, the gear teeth, 2, spanner, 201, pulling teeth.
Embodiment
Below in conjunction with specific embodiment the utility model is further specified.
Referring to Fig. 2, Fig. 3, the valve handle main body is the annulus bodily form, and its periphery is provided with the gear teeth 1 that equidistant permutation distributes, and contains recess between the gear teeth and the gear teeth.The elongation line of the gear teeth 1 side is intersected in the center of described valve handle.Be convenient to processing.The tooth depth of the gear teeth 1 is 20-100mm.
Referring to Fig. 4, Fig. 4 is the spanner corresponding with valve handle, and spanner 2 is provided with two pulling teeth 201, and pulling teeth 201 is corresponding with recess.
Referring to Fig. 5, pulling teeth 201 inserts in described any two recesses, rotary spanner, and the rotating valve handwheel has reached the labour-saving effect.
