Description

The Electric Explosion-proof fixing ball valve of band sealing
Technical field
The utility model relates to a kind of valve, especially relates to a kind of fixing ball valve of the Electric Explosion-proof with sealing.
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 fixing ball valve of the Electric Explosion-proof with sealing, 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 Electric Explosion-proof fixing ball valve of band sealing of the present utility model, comprise the left valve barrel and the right valve barrel that are fixed together, respectively be provided with a valve seat in described left valve barrel and right valve barrel, left, be provided with flap in right valve barrel, flap is comprised of the conical surface at cylindrical body and cylindrical body two ends, the flap upper end is connected with valve rod, the valve rod upper end is connected with Vidacare corp, the flap lower end is connected with rotating shaft, the rotating shaft cross-under is in right valve barrel, the right valve barrel lower end is provided with capping, right valve barrel upper end connection bracket, Vidacare corp is fixed on support, valve rod is provided with Gland, the Gland lower end is provided with filler, the filler below is provided with sealing cover, sealing cover and right valve barrel, all be provided with multiple-sealed circle between valve gap, the right valve barrel bottom is provided with the pressure release bolt.
As preferably, described Vidacare corp is connected with handwheel.
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 Electric Explosion-proof fixing ball valve of the band sealing of this example, as Fig. 1, comprise the left valve barrel 1 and right valve barrel 2 that are fixed together, respectively be provided with a valve seat 3 in left valve barrel and right valve barrel, left, be provided with flap 4 in right valve barrel, flap is comprised of the conical surface at cylindrical body and cylindrical body two ends, the flap upper end is connected with valve rod 5, the valve rod upper end is connected with Vidacare corp 6, the flap lower end is connected with rotating shaft 7, the rotating shaft cross-under is in right valve barrel, the right valve barrel lower end is provided with capping 8, right valve barrel upper end connection bracket 9, Vidacare corp is fixed on support, valve rod is provided with Gland 10, the Gland lower end is provided with filler 12, the filler below is provided with sealing cover 13, sealing cover and right valve barrel, all be provided with multiple-sealed circle between valve gap, the right valve barrel bottom is provided with pressure release bolt 14.Vidacare corp is connected with handwheel 11.
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.
