Abstract
The utility model relates to a valve, in particular to a butterfly valve with a handwheel. The butterfly valve with the handwheel is mainly used for solving the technical problems that in the prior art, a valve is complex in structure, high in manufacturing cost, inconvenient to open and close and short in service life. The butterfly valve with the handwheel comprises a valve body (1). The butterfly valve with the handwheel is characterized in that a valve rod (2) is arranged in the valve body (1), a butterfly plate (4) is fixed in the middle of the valve rod through a taper pin (3), a bottom cover (5) is connected with the lower end of the valve rod, supports (6) are fixed at the upper end of the valve body, a worm gear case (7) is fixed at the upper ends of the supports, the worm gear case is connected with a driving valve rod, and the worm gear case is further connected with the handwheel (9).
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of butterfly valve with handwheel.
Background technique
Valve is controlling component in the pipeline fluid delivery system, and it is to change path section and media flow direction, has water conservancy diversion, by functions such as, throttling, non-return, shunting or overflow releases.The valve that is used for fluid control, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are various.Valve can be used for controlling all kinds fluid ground such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid and flows, the working pressure of valve can be from 0.0013MPa to 1000MPa ultrahigh pressure, operating temperature is from the high temperature of-269 ℃ ultralow temperature to 1430 ℃.The control of valve can be adopted the multiple kind of drive, as manual, electronic, surge, pneumatic, worm gear, electromagnetism is moving, electricity surges, gas-liquid is moved, spur wheel, umbrella gear driving etc.; Can be under the effect of pressure, temperature or other form transducing signal, by predetermined requirement action, valve relies on and drives or automechanism makes it do lifting, slippage, swing or rotation motion, thus the size that changes its Flow area is to realize its control function.But existing valve mechanism is comparatively complicated, and manufacture cost is higher, opens and closes comparatively inconvenience, and working life is shorter.
The model utility content
The utility model provides a kind of butterfly valve with handwheel, and it mainly is that to solve the existing in prior technology valve mechanism comparatively complicated, and manufacture cost is higher, opens and closes comparatively inconvenience, the technical problem that working life is short etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The butterfly valve of band handwheel of the present utility model, comprise valve body, be provided with valve rod in the described valve body, fixedly there is butterfly plate at the valve rod middle part by taper pin, the valve rod lower end is connected with bottom, and fixedly there is bearing the valve body upper end, and fixedly there is Worm gear case the bearing upper end, Worm gear case connects actuate valve stem, and Worm gear case also is connected with handwheel.
As preferably, the two ends, the left and right sides of described valve body all are provided with adpting flange.
Therefore, valve mechanism of the present utility model is comparatively simple, reasonable, and manufacture cost is lower, and it is comparatively convenient to process, and it is comparatively easy to open and close, and working life is higher.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the butterfly valve of the band handwheel of this example, as Fig. 1, comprise valve body 1, be provided with valve rod 2 in the valve body, fixedly there is butterfly plate 4 at the valve rod middle part by taper pin 3, and the valve rod lower end is connected with bottom 5, fixedly there is bearing 6 the valve body upper end, fixedly there is Worm gear case 7 the bearing upper end, and Worm gear case connects actuate valve stem, and Worm gear case also is connected with handwheel 9.The two ends, the left and right sides of valve body all are provided with adpting flange 8.
The above only is specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
Claims (2)
