Abstract
The utility model relates to a valve, in particular to a butterfly valve with good sealing performance. 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 a valve rod (2) is arranged inside the valve body (1), a butterfly plate (4) is fixed in the middle of the valve rod through a taper pin (3), the lower end of the valve rod is connected with a bottom cover (5), a pressing plate (6) is arranged inside the portion, where the butterfly plate is arranged, of the valve body, and a multilayer seal ring (7) is arranged inside the pressing plate.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of high leak tightness butterfly valve.
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 high leak tightness butterfly valve, 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:
High leak tightness butterfly valve of the present utility model comprises valve body, is provided with valve rod in the described valve body, and fixedly there is butterfly plate at the valve rod middle part by taper pin, and the valve rod lower end is connected with bottom, and the valve inner at butterfly plate place is provided with pressing plate, and pressing plate inside is provided with multi-layer sealing ring.
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 high leak tightness butterfly valve that this is routine as Fig. 1, comprises 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, the valve inner at butterfly plate place is provided with pressing plate 6, and pressing plate inside is provided with multi-layer sealing ring 7.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.
