Abstract
The utility model relates to a valve, in particular to a butterfly valve with double rotary shafts. The butterfly valve mainly solves the technical problems that a valve in the prior art is complex in structure, high in manufacturing cost, inconvenient to open and close, short in service life and the like. The butterfly valve comprises a valve body (1) and is characterized in that the upper rotary shaft (2) and the lower rotary shaft (3) are connected to the upper end and the lower end of the valve body (1) respectively in a penetrated mode, an end cover (4) is arranged on the end face, at the lower end of the lower rotary shaft (3), of the valve body (1), a valve plate (5) is connected between the upper rotary shaft (2) and the lower rotary shaft (3), one side of the valve plate (5) is a plane, the other side of the valve plate (5) is a cambered surface, the outer circle of the upper rotary shaft (2) and the outer circle of the lower rotary shaft (3) are respectively provided with a shaft sleeve (6), and a hand wheel (8) is connected to the upper end of the upper rotary shaft (2) through a transmission device (7).
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of butterfly valve with two rotating shafts.
Background technique
Valve is controlling component in pipeline fluid transporting system, and it is for changing path section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.The valve of controlling for fluid, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are various.Valve can be used for controlling all kinds such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid and fluidly flows, the working pressure of valve can be from 0.0013MPa to 1000MPa ultrahigh pressure, operating temperature is from the high temperature of the ultralow temperature to 1430 of-269 ℃ ℃.The control of valve can adopt the multiple kind of drive, as manual, electronic, surge, pneumatic, worm gear, electromagnetic driven, electricity surge, air-or liquid-operated, 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 driving or automechanism to make 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, open and close comparatively inconvenience, working life is shorter.
Model utility content
The utility model is to provide a kind of butterfly valve with two rotating shafts, and it is mainly that to solve the existing valve mechanism of prior art comparatively complicated, and manufacture cost is higher, opens and closes comparatively inconvenience, working life shorter grade technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The butterfly valve of the two rotating shafts of band of the present utility model, comprise valve body, there are upper rotating shaft, lower rotary shaft in the two ends up and down of described valve body respectively cross-under, the valve body end face of lower rotary shaft lower end is provided with end cap, between upper and lower rotating shaft, be connected with valve plate, a side of valve plate is plane, and opposite side is cambered surface, the cylindrical of upper and lower rotating shaft is provided with axle sleeve, and upper rotating shaft upper end is connected with handwheel by transmission device.
As preferably, described upper rotating shaft is provided with Gland, and Gland bottom is provided with filler.
Therefore, valve mechanism of the present utility model is comparatively simple, reasonable, and manufacture cost is lower, and more for convenience, it is comparatively easy to open and close in processing, and working life is higher.
Accompanying drawing explanation
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 two rotating shafts of band of this example, as Fig. 1, comprise valve body 1, there are upper rotating shaft 2, lower rotary shaft 3 in the two ends up and down of valve body respectively cross-under, and the valve body end face of lower rotary shaft lower end is provided with end cap 4, is connected with valve plate 5 between upper and lower rotating shaft, one side of valve plate is plane, opposite side is cambered surface, and the cylindrical of upper and lower rotating shaft is provided with axle sleeve 6, and upper rotating shaft upper end is connected with handwheel 8 by transmission device 7.Upper rotating shaft is provided with Gland 9, and Gland bottom is provided with filler 10.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
