Abstract
The utility model relates to a valve, in particular to an eccentric ball valve with the high sealing performance. The eccentric ball valve mainly solves the technical problem that in the prior art, a valve 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 cover (3) is connected to the upper end of the valve body (1), a valve rod (4) is connected in the valve cover (3) in a penetrating 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), a sealing ring (7) is arranged at the position where the valve rod (4) is connected with the eccentric ball valve clack (5), a separating sleeve (9) is arranged at the upper end of the sealing ring (7), and padding (10) is arranged at the upper end of the valve rod (4).
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of eccentric ball valve of high leak tightness.
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 of high leak tightness, 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 eccentric ball valve of high leak tightness of the present utility model, comprise valve body, described valve body is provided with water inlet and outlet flange, valve body upper end is connected with valve gap, and in valve gap, cross-under has valve rod, and 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, the joint of valve rod and eccentric sphere flap is provided with seal ring, and the upper end of seal ring is provided with spacer, and the upper end of valve rod is provided with filler.
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 of the high leak tightness that this is routine, as Fig. 1, comprise valve body 1, valve body is provided with water inlet and outlet flange 2, and valve body upper end is connected with valve gap 3, in valve gap, cross-under has valve rod 4, 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, and the joint of valve rod and eccentric sphere flap is provided with seal ring 7, the upper end of seal ring is provided with spacer 9, and the upper end of valve rod is provided with filler 10.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.
