Abstract
The utility model relates to a valve, in particular to a pneumatic single-seat regulating valve. The technical problems that a valve structure is more complex, the manufacturing cost is higher, a vale is inconvenient to open and close, the service life is shorter, and the like in the prior art are solved. The pneumatic single-seat regulating valve comprises a valve body (1), wherein a left inlet/outlet (2) and a right inlet/outlet (3) are formed in the valve body (1); both the left inlet/outlet and the right inlet/outlet are arc-shaped channels; a valve seat (4) is arranged in a position where an inner end of the left inlet/outlet is communicated with an inner end of the right inlet/outlet; a lower support (5) is fixed at the upper end of the valve body; valve rods (6) are arranged in the valve body and the lower support; lower ends of the valve rods are connected with valve cores (7) which can block the valve seat; the upper end of the lower support (5) is connected with an upper support (8); upper and lower casings (9) are arranged at the top end of the upper support; a pneumatic film (10) is connected between the upper and lower casings; and a lifting support plate (11) is arranged on the lower surface of the pneumatic film and connected with a spring (12).
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of Pneumatic single-seat modulating valve.
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 Pneumatic single-seat modulating valve, 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:
Pneumatic single-seat modulating valve of the present utility model, comprise valve body, described valve body is provided with left import and export, right import and export, left import and export and right import and export are all curved channel, the inner connectivity part of left import and export and right import and export is provided with valve seat, the valve body upper end is fixed with lower support frame, be provided with valve rod in valve body, lower support frame, the valve rod lower end is connected with the spool that can stop up valve seat, the lower support frame upper end is connected with upper bracket, and the upper bracket top is provided with lower casing, between upper lower casing, is connected with air bladder, the lower surface of air bladder is provided with the lifting support plate, lifting support plate linking springs.
As preferably, described upper lower casing is connected with relief opening.
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 Pneumatic single-seat modulating valve that this is routine, as Fig. 1, comprise valve body 1, valve body) be provided with left import and export 2, right import and export 3, left import and export and right import and export are all curved channel, the inner connectivity part of left import and export and right import and export is provided with valve seat 4, the valve body upper end is fixed with lower support frame 5, valve body, be provided with valve rod 6 in lower support frame, the valve rod lower end is connected with the spool 7 that can stop up valve seat, the lower support frame upper end is connected with upper bracket 8, the upper bracket top is provided with lower casing 9, be connected with air bladder 10 between upper lower casing, the lower surface of air bladder is provided with lifting support plate 11, lifting support plate linking springs 12.Upper lower casing is connected with relief opening 13.
