Abstract
The utility model relates to a valve, in particular to an eccentric ball valve with an integrated connecting flange. The eccentric ball 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 eccentric ball valve comprises a valve body (1) and is characterized in that a water inlet-and-outlet flange (2) is arranged on the valve body (1), a valve deck (3) is connected to the upper end of the valve body (1), a valve rod (4) is connected to the interior of the valve deck (3) in a penetrated mode, an eccentric ball valve clack (5) is connected to the lower end of the valve rod (4), the inner surface and the outer surface of the eccentric ball valve clack (5) are respectively covered with a sealing layer (6), the connecting flange (7) is connected to the valve deck (3), the valve deck (3) and the connecting flange (7) are integrally formed, an annular groove is formed in the upper end of the valve body (1), and the valve deck (3) is welded to the interior of the annular groove.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of eccentric ball valve with integral type adpting flange.
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 eccentric ball valve with integral type adpting flange, 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:
Eccentric ball valve with integral type adpting flange of the present utility model, comprise valve body, described valve body is provided with water inlet and outlet flange, and valve body upper end is connected with valve gap, and in valve gap, cross-under has valve rod, valve rod lower end is connected with eccentric sphere flap, the inner and outer surface of eccentric sphere flap is all coated with one deck sealing layer, is connected with adpting flange on valve gap, and valve gap and adpting flange are that integral type is made, valve body upper end is provided with annular groove, and valve gap is welded in annular groove.
As preferably, the interior edge face of described water inlet and outlet flange is provided with the conical surface, and sealing layer is provided with the projection of the conical surface of can fitting.
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 eccentric ball valve with integral type adpting flange of this example, as Fig. 1, comprise valve body 1, valve body is provided with water inlet and outlet flange 2, valve body upper end is connected with valve gap 3, in valve gap, cross-under has valve rod 4, and valve rod lower end is connected with eccentric sphere flap 5, and the inner and outer surface of eccentric sphere flap is all coated with one deck sealing layer 6, on valve gap, be connected with adpting flange 7, valve gap and adpting flange are that integral type is made, and valve body upper end is provided with annular groove, and valve gap is welded in annular groove.The interior edge face of water inlet and outlet flange is provided with the conical surface, and sealing layer 6 is provided with the projection 8 of the conical surface of can fitting.
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.
