Abstract
The utility model relates to a valve, in particular to a gate valve which is easy to assemble. The gate valve mainly solves the technical problems that a valve is relatively complicated in structure, higher in manufacturing cost, relatively inconvenient to open and close, and shorter in service life in the prior art. The gate valve comprises a valve body (1), and is characterized in that a valve seat (2) is arranged in the valve body (1); each of the two ends of the valve body is in threaded connection with a flange connector (3); a valve rod (4) is connected in the valve body in a penetrating manner; a gate plate (5) capable of sealing the valve seat is arranged at the lower end of the valve rod; a section of the gate plate is inverted-trapezoidal; a sealing ring (6) is embedded into the outer surface of the gate plate; a valve cover (7) is fixed at the upper end of the valve body; and a hand wheel (8) is arranged at the upper end of the valve cover and connected with the valve rod.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of gate valve of easy assembling.
Background technique
Valve is controlling component in the 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 and drives or automechanism makes it do lifting, slippage, swing or rotation motion, thus the size that changes its Flow area is controlled function to realize it.But existing valve mechanism is comparatively complicated, and manufacture cost is higher, open and close comparatively inconvenience, working life is shorter.
The model utility content
The utility model is to provide a kind of gate valve of easy assembling, 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 gate valve of easy assembling of the present utility model, comprise valve body, be provided with valve seat in described valve body, the two ends of the valve body flange-interface that has been threaded respectively, in valve body, cross-under has valve rod, and the valve rod lower end is provided with the flashboard of salable valve seat, the section of flashboard is inverted trapezoidal, its outer surface is embedded with seal ring, and the valve body upper end is fixed with valve gap, and the valve gap upper end is provided with handwheel and connects valve rod.
As preferably, the junction plane of described valve body and valve gap is provided with the Expanded graphite spirotallic gasket.
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.
The 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 gate valve of the easy assembling of this example, as Fig. 1, comprise valve body 1, be provided with valve seat 2 in valve body, the two ends of the valve body flange-interface 3 that has been threaded respectively, in valve body, cross-under has valve rod 4, the valve rod lower end is provided with the flashboard 5 of salable valve seat, and the section of flashboard is inverted trapezoidal, and its outer surface is embedded with seal ring 6, the valve body upper end is fixed with valve gap 7, and the valve gap upper end is provided with handwheel 8 and connects valve rod.The junction plane of valve body and valve gap is provided with Expanded graphite spirotallic gasket 9.
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 all are encompassed among the scope of the claims of the present utility model.
Claims (2)
