According to the connecting structure of the valve handle, a valve comprises a valve rod, wherein a plurality of splines are uniformly distributed on the outer side wall of the end part of the valve rod; the handle is provided with a connecting hole; key slots are uniformly distributed on the inner wall of the connecting hole; the connecting structure comprises a connecting sleeve fixedly connected to the end face of the handle; the connecting sleeve and the connecting hole are arranged coaxially, and are sleeved on the splines; and a positioning mechanism which can be used for fixing the handle in an axial direction is arranged between the inner wall of the connecting sleeve and the splines. Due to the adoption of the connecting structure of the valve handle, the valve can be prevented from being opened wrongly.
Description
Technical field
The utility model belongs to the valve part technical field, relates to a kind of linkage structure of valve handle.
Background technique
Valve is industrial a kind of important fluid control devices, relates to the national economy many departments, is the development fundamental equipments of national economy.Through the development of decades, China's valve products has formed tens large classes, especially is being sure to occupy prostatitis, the world aspect number of the enterprise and the volume of production and marketing two.Valve 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.Valve also is divided into the valve materials such as cast iron valve, cast steel valve, stainless valve, Plastic valve according to material.
Valve generally comprises the valve rod that valve body, flap and control flap rotate, and also can be connected with valve handle on valve rod, is used for rotation valve rod, because the frequent stressed use of valve handle, so its structure is important.Chinese utility model patent application (201120119236.9) discloses a kind can multiple tooth work, and bearing capacity is high, centering is good, stress is concentrated the minor valve handle, comprise handle body, handle body is provided with the hole that is connected with valve rod, and the hole that is connected with valve rod on the described handle body is splined hole.Adopt the valve handle of the utility model structure, adopt the splined hole structure, can effectively solve defective of the prior art, increase the working life of valve handle, and improve the performance accuracy of valve.But in the real life process, outside valve often is exposed to, meeting rotating valve handle when some children play, thus cause valve to be opened by mistake, in some field, this will cause serious consequence.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of linkage structure of valve handle, and the linkage structure of this valve handle can avoid valve to be opened by mistake.
The purpose of this utility model can realize by following technical proposal: a kind of linkage structure of valve handle, described valve comprises a valve rod, outer side wall in the valve rod end is evenly equipped with some splines, offer attachment hole on the described handle, inwall at attachment hole is evenly equipped with the keyway that some and above-mentioned spline matches, it is characterized in that, described linkage structure comprises that one is connected in the connecting sleeve on the handle end face, described connecting sleeve and attachment hole concentric arrange, and be set on the spline, be provided with the positioning means that can carry out to handle axial restraint between described connecting sleeve inwall and the spline.
Flap in valve rod and the valve body is connected, and is used for rotating flap; Valve handle is connected on the valve rod by connecting sleeve, and by positioning means valve handle is carried out axially locating, and circumferentially unfixing; Only be the sheathed spline of connecting sleeve this moment, and spline does not match with keyway, if having people's misoperation valve handle, valve handle only can dally at valve rod this moment, and can not be with ovable valve stem to rotate; If in the time of need to opening valve, firmly press down valve handle, the axially locating of positioning means is removed, and the spline of valve rod is matched with the keyway of valve handle.
In the linkage structure of above-mentioned valve handle, described positioning means comprises that positioning means (3) comprises the some blind holes that are opened on the spline, described blind hole is radially offered along valve rod, in blind hole, be equipped with a steel ball, be provided with spring between described steel ball and the blind hole bottom surface, an end of this spring is pressed on the blind hole bottom surface, and the other end is pressed on the steel ball, circumferentially offer a groove on the inwall of described connecting sleeve, above-mentioned steel ball is pressed in the groove.Groove circumferentially is opened on the connecting sleeve inwall ringwise, and steel ball is pressed in the groove, and its pressure plays axially locating to connecting sleeve, and this moment the rotating valve handle, steel ball rolls in groove and can not break away from groove.
In the linkage structure of above-mentioned valve handle, the quantity of described blind hole has two, and these two blind holes axially to it.Blind hole is too many, and then the mechanical strength of valve rod upper spline dies down, thereby has affected the join strength of spline and keyway; Blind hole very little, then to the axially locating insufficient strength of connecting sleeve.
In the linkage structure of above-mentioned valve handle, the cross section of described groove is circular-arc, and the arc radius radius of this groove is consistent with the radius of steel ball.The radius of groove cross section is consistent with the radius of steel ball, so that both cooperate closely, increases axially locating intensity.
In the linkage structure of above-mentioned valve handle, described groove inwall and connecting sleeve inwall arc transition.Prevent that steel ball is stuck in groove.
Compared with prior art, the linkage structure of this valve handle has the following advantages:
1, because valve handle is connected on the valve rod by connecting sleeve, and by positioning means valve handle is carried out axially locating, and circumferentially fixing, so during the misoperation valve handle, valve handle only can dally at valve rod, and can not be with ovable valve stem to rotate.
2, because positioning means carries out axially locating by the mode that steel ball compresses groove, simple in structure, and the cancellation location is convenient.
