Abstract
The utility model relates to a valve, in particular to a pneumatic single-seat regulating valve with a limiting switch. The pneumatic single-seat regulating 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 pneumatic single-seat regulating valve comprises a valve body, a left in-out opening and a right in-out opening are formed in the valve body, both the left in-out opening and the right in-out opening are arc-shaped channels, a valve seat is arranged at the position where the inner end of the left in-out opening is communicated with the inner end of the right in-out opening, a lower support is fixed to the upper end of the valve body, a valve rod is arranged inside the valve body and the lower support, a valve element capable of blocking the valve seat is connected to the lower end of the valve rod, an upper support is connected to the upper end of the lower support, an upper outer shell and a lower outer shell are arranged at the top end of the upper support, a pneumatic thin film is connected between the upper outer shell and the lower outer shell, a pointer block is connected to the position, where the upper support is arranged, of the valve rod, and the limiting switch provided with identification scales is arranged on the upper support.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of Pneumatic single-seat modulating valve with limit switch.
Background technique
Valve is controlling component in 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 driving or automechanism to make 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, open and close comparatively inconvenience, working life is shorter.
Model utility content
The utility model is to provide a kind of Pneumatic single-seat modulating valve with limit switch, 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 with limit switch 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, valve body upper end is fixed with lower support frame, valve body, in lower support frame, be provided with valve rod, valve rod lower end is connected with the spool that can stop up valve seat, lower support frame upper end is connected with upper bracket, upper bracket top is provided with lower casing, between upper lower casing, be connected with air bladder, on the valve rod at upper bracket place, be connected with pointer blocks, upper bracket is provided with the limiting stopper of sign scale.
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.
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 with limit switch of this example, as Fig. 1, comprise valve body 1, valve body is 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, valve body upper end is fixed with lower support frame 5, valve body, in lower support frame, be provided with valve rod 6, valve rod lower end is connected with the spool 7 that can stop up valve seat, lower support frame upper end is connected with upper bracket 8, upper bracket top is provided with lower casing 9, between upper lower casing, be connected with air bladder 10, on the valve rod at upper bracket place, be connected with pointer blocks 11, upper bracket is provided with the limiting stopper 12 of sign scale.Upper lower casing is connected with relief opening 13.
