Abstract
The utility model relates to a valve, in particular to a gate valve provided with an easily assembled handle wheel, and mainly solves the technical problems that a valve in the prior art is more complicated in structure, higher in manufacturing cost, inconvenient to open or close, shorter in service life and the like. The gate valve comprises a valve body (1), and is characterized in that a valve seat (2) is arranged in the valve body (1); one flange port (3) is in threaded connection with each of two ends of the valve body respectively; a valve rod (4) penetrates through the valve body; a gate plate (5) capable of sealing the valve seat is arranged at the lower end of the valve rod; a valve cap (7) is fixed at the upper end of the valve body; a valve rod nut (6) is arranged in the upper end of the valve cap; the valve rod penetrates through the valve rod nut; a hand wheel (8) is fixed at the upper end of the valve rod nut through a fixing nut (10); and the hand wheel is connected with the valve rod.
Description
Technical field
The utility model relates to a kind of valve, especially relates to the easily gate valve of assembling of a kind of handwheel.
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 the easily gate valve of assembling of a kind of handwheel, 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:
Handwheel of the present utility model is the gate valve of assembling easily, 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, the valve rod lower end is provided with the flashboard of salable valve seat, the valve body upper end is fixed with valve gap, and inside, valve gap upper end is provided with Stem Mut, and the valve rod cross-under is in Stem Mut, the Stem Mut upper end is fixed with handwheel by set screw nut, and handwheel 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: this routine handwheel is the gate valve of assembling easily, 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, and the valve rod lower end is provided with the flashboard 5 of salable valve seat, and the valve body upper end is fixed with valve gap 7, inside, valve gap upper end is provided with Stem Mut 6, the valve rod cross-under is in Stem Mut, and the Stem Mut upper end is fixed with handwheel 8 by set screw nut 10, and handwheel 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.
