Description
Technical field
The utility model belongs to the valve fittings technical field, relates to a kind of handwheel, particularly a kind of valve handle.
Background technique
Valve is the control gear of fluid circuit, and its fundamental function is the circulation that switches on or off the pipeline medium, changes the circulation of medium, changes the flow direction of medium, regulates the pressure and the flow of medium, the normal operation of the equipment of protection pipeline.Along with the continuous development of modern industry, valve uses very extensive as a kind of conventional machinery accessory.The handwheel of valve plays requisite effect in valve operation.The handwheel of existing valve mainly contains two kinds: iron casting spare and sheet metal stamping part, and iron casting spare heaviness and cost height, the stamping part compressive resistance is weak, intensity is little and working life is short.
For solving above-mentioned this problem, so people have just invented a kind of valve handle, for example, Chinese patent literature once disclosed a kind of valve handle [China Patent No.: ZL200820213184.X; Notice of authorization number: CN201297440Y], comprise wheel rim, spoke, wheel hub, on wheel rim corresponding between adjacent per two spokes, have the longitudinal wave Slippage.
Though above-mentioned valve handle has improved wheel body intensity to a certain extent, but also have following defective: above-mentioned longitudinal wave Slippage, stiffening rib etc. all act on wheel rim and the spoke, when rotating wheel rim, carry whole torsional moments with the wheelboss side wall that valve rod directly is connected by the grafting form, the damages such as distortion, fracture that easily are distorted, thus the intensity and the life-span of valve handle influenced.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of valve handle that can improve the joint intensity that is connected with valve rod.
The purpose of this utility model can realize by following technical proposal: a kind of valve handle, comprise the handwheel handle, described handwheel handle is provided with and can be connected and drives the joint that valve rod rotates with valve rod, lobed connecting end on the joint, it is characterized in that: be connected with several stiffening ribs between described connecting end and the above-mentioned handwheel handle, described stiffening rib can be strengthened the intensity of above-mentioned connecting end and handwheel handle respectively.
The connection part of this valve handle is in the middle part of handwheel handle, and joint one end is connected mutually with the handwheel handle, and the other end has the connecting end that is projection; Stiffening rib is lath-shaped, and the one end is connected mutually with the handwheel handle, the other end is connected mutually with the sidewall of the connecting end of projection, when driving the valve rod rotation when rotation handwheel handle and by connecting end, the connecting end sidewall is subjected to warping force, thereby stiffening rib reaches the effect of strengthening connecting end and handwheel handle, prolongs the life-span of valve handle.
In above-mentioned valve handle, described stiffening rib is 2～8.Stiffening rib can circumferentially evenly distribute, and helps even bearing capacity, guarantees the intensity of valve handle; The quantity that stiffening rib is provided with is many more, and the intensity of valve handle is high more, but the quantity of stiffening rib too much is provided with, and causes waste of material, cost to improve again, so that stiffening rib quantity is suitable for is suitable.
In above-mentioned valve handle, described joint and above-mentioned handwheel handle are that integral type is connected and forms.Integral structure has improved the intensity that is connected of joint and handwheel handle, and stiffening rib is fixedly arranged between joint and the handwheel handle simultaneously, and integral body has improved the intensity of valve handle body, has increased the extreme value of valve handle carrying warping force.
In above-mentioned valve handle, the connecting end on the described joint have on it can with the groove of valve rod socket connection.Groove and valve rod cross section are complementary, and its valve rod that can drive grafting rotates synchronously.
In above-mentioned valve handle, described groove shapes is that rectangular is square or oval.After groove shapes can make the valve rod of corresponding cross section peg graft, drive valve rod by the handwheel handle and rotate.
In above-mentioned valve handle, described handwheel handle is the housing with cavity, has opening on the housing, and described cavity is connected with the external world by above-mentioned opening.Connection part is in cavity, and valve rod is by opening and connecting end socket connection, and the outer side surface of housing is an arc shaped surface, and the outer side surface of arc is convenient to effectively reverse the application of force as stress surface.
In above-mentioned valve handle, described housing is positioned at opening and is provided with flange.Be stability and intensity that the peripheral annular flange can increase arc shell, make it not yielding under external force, the appearance and modeling of having beautified valve handle simultaneously.
In above-mentioned valve handle, described hull outside face is provided with some tread plates.The tread plate that is protruding strip vertically is fixedly arranged on the hull outside face, when preventing the application of force and smooth hull outside face produce circumferentially and slide, thereby guarantee the useful effect of the application of force.
In above-mentioned valve handle, described tread plate is 1～8.The tread plate quantity that evenly distributes and select to suit can effectively be eliminated and the circumferential displacement of sliding and being produced of arc shell outer side surface, improves the efficient of rotation urging to greatest extent.
In above-mentioned valve handle, described housing adopts plastics to make.Plastic materials have anticorrosive property, anti-wear and cheap, processing is easy, characteristics such as conveniently transport, be widely used.
Compared with prior art, the stiffening rib of this valve handle directly is fixed on the sidewall of connecting end on the joint, when connecting end sidewall carrying torsional moment, stiffening rib can evenly carry warping force, improved and rotated stressed stability, reliability, improve the stressed ultimate strength of valve handle, increased the life-span of valve handle.
