Abstract
The utility model relates to a valve, in particular to an electric and high-pressure cast steel gate valve with folding edges. The electric and high-pressure cast steel gate valve with the folding edges mainly solves the technical problems that an existing 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 electric and high-pressure cast steel gate valve with the folding edges comprises a valve body, wherein a steam inlet-outlet is formed in the lower end of the valve body, a valve rod is arranged in the valve body, a gate board capable of blocking the steam inlet-outlet is connected with the lower end of the valve rod, a piston is connected in the middle of the valve rod, a worm-and-gear transmission device is connected at the top of the valve rod and connected with a hand wheel, a first folding edge, a second folding edge and a third folding edge are arranged at the outer end face of the steam inlet-outlet, the included angle between the first folding edge and the vertical plane is 45 degrees, the included angle between the second folding edge and the horizontal plane is 30 degrees, the included angle between the third folding edge and the vertical plane is 37.5 degrees, and a support is connected at the upper end of the valve body.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of electronic high pressure cast steel gate valve with flanging.
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 electronic high pressure cast steel gate valve with flanging, 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:
The electronic high pressure cast steel gate valve of band flanging of the present utility model, comprise valve body, described valve body lower end is provided with the turnover steam port, be provided with valve rod in the valve body, the valve rod lower end is connected with the flashboard that can stop up the turnover steam port, the valve rod middle part is connected with piston, the valve rod top is connected with worm gearing, worm gearing is connected with handwheel, the exterior edge face of turnover steam port is provided with first flanging, second flanging, the 3rd flanging, the angle of first flanging and vertical plane are 45 °, and the angle of second flanging and horizontal plane is 30 °, the angle of the 3rd flanging and vertical plane is 37.5 °, and the valve body upper end is connected with support.
As preferably, be provided with four cyclizations, pressure ring, seal ring between described valve interior wall and the piston.
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 electronic high pressure cast steel gate valve of the band flanging of this example, as Fig. 1, comprise valve body 1, valve body lower end is provided with turnover steam port 2, be provided with valve rod 3 in the valve body, the valve rod lower end is connected with the flashboard 4 that can stop up the turnover steam port, the valve rod middle part is connected with piston 5, the valve rod top is connected with worm gearing 6, and worm gearing is connected with handwheel 7, and the exterior edge face of turnover steam port is provided with first flanging 8, second flanging 9, the 3rd flanging 14, the angle of first flanging and vertical plane is 45 °, the angle of second flanging and horizontal plane is 30 °, and the angle of the 3rd flanging and vertical plane is 37.5 °, and the valve body upper end is connected with support 10.Be provided with four cyclizations 11, pressure ring 12, seal ring 13 between valve interior wall and the piston.
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.
