Summary of the invention
The purpose of this utility model is: provide a kind of pneumatic control, flow control accuracy height, pneumatic control valve that volume is little of adopting, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises valve body (1), valve body (1) is provided with material feeding mouth (2) and discharge port (3), spool (4) and valve seat (12) are installed in valve body (1), spool (4) is gone up and is connected valve rod (5), on valve body (1), be fixed with support (7), support (7) is gone up and is connected pneumatic actuator (6), and the main shaft (8) of pneumatic actuator (6) connects valve rod (5).
Above-mentioned pneumatic control valve, pneumatic actuator (6) adopts piston type cylinder, also be provided with electropneumatic valve positioner (14) and air-filtering reduction valve (13) on support (7), pneumatic actuator (6) connects electropneumatic valve positioner (14) and air-filtering reduction valve (13) by tracheae.Electropneumatic valve positioner (14) is regulated valve rod (5) stroke of pneumatic actuator (6), and air-filtering reduction valve (13) works pressure and the filtered air of regulating air, thereby prolongs the effect of life of valve.
Above-mentioned pneumatic control valve, main shaft (8) connects valve rod (5) by coupling (9) in the middle of support (7), and it is convenient to install and change.
Above-mentioned pneumatic control valve is provided with scale (10) on support (7), be provided with pointer (11) on coupling (9), by the aperture of scale (10) and pointer (11) expression spool (4).
Pipeline in the above-mentioned pneumatic control valve, valve body (1) is the S type, and valve seat (12) is installed in the middle of the S-shaped pipe road, and S-shaped pipe road control flow rate is more accurate.
Above-mentioned pneumatic control valve, valve seat (12) is installed in intermediate portion at valve body (1), on valve seat (12), be provided with rubber seal (15), by rubber seal (15), valve seat (12) forms the soft and hard seal structure, axially be hard sealing, radially be soft seal, thereby guaranteed that valve detection is accurate, zero leakage.
The utility model adopts the pneumatic actuator of charged pneumatic valve positioner to carry out flow control, reduced the volume and weight of modulating valve, and the precision of pneumatic adjusting is higher, and using effect is better.Valve seat employing soft and hard seal structure axially is hard sealing, radially is soft seal, thereby has guaranteed that valve detection is accurate, zero leakage.Therefore compare with prior art, the utlity model has flow control accuracy height, simple in structure, advantages such as volume is little, zero leakage, be applicable to various modulating valve.
Description of drawings: accompanying drawing 1 is a structural representation of the present utility model.
