Abstract
The utility model relates to a valve, in particular to a fuel gas brake valve with good sealing performance. The fuel gas brake valve mainly solves the technical problems that a 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 fuel gas brake valve comprises a valve body (1) and is characterized in that an upper case body (3) is fixed at the upper end of the valve body (1) through a stud (2), an air inlet-outlet (4) is formed in the valve body, a valve rod (5) is arranged inside the valve body, the valve rod is connected with a valve clack (6) which can seal the air inlet-outlet, the upper end of the upper case body is connected with a pressing plate (7), and a sealing plate (9) is connected into the pressing plate through a compressing sealing part (8).
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of high leak tightness Gas-combustion valve.
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 high leak tightness Gas-combustion valve, 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:
High leak tightness Gas-combustion valve of the present utility model, comprise valve body, fixedly there is upper shell described valve body upper end by stud bolt, valve body is provided with air inlet/outlet, be provided with valve rod in the valve body, valve rod is connected with the flap that can seal air inlet/outlet, and the upper shell upper end is connected with pressing plate, is connected with seal disc by compressing Sealing in the pressing plate.
As preferably, be connected with handwheel on the described valve rod.
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 high leak tightness Gas-combustion valve that this is routine, as Fig. 1, comprise valve body 1, fixedly there is upper shell 3 the valve body upper end by stud bolt 2, valve body is provided with air inlet/outlet 4, is provided with valve rod 5 in the valve body, and valve rod is connected with the flap 6 that can seal air inlet/outlet, the upper shell upper end is connected with pressing plate 7, is connected with seal disc 9 by compressing Sealing 8 in the pressing plate.The valve rod upper end is connected with handwheel 10.
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.
