Description
Technical field
The utility model relates to the valve location control field of water-sealing valve, relates in particular to a kind of step-less adjustment location actuating device.
Background technique
In the metallurgy industry; The coal of coal tar chamber can produce the great amount of high-temperature raw coke oven gas in the high-temp combustion process; Get into water-sealing valve through asending pipe; Water-sealing valve plays the effect of control raw coke oven gas flow in the coke oven gas gathering system, the step-less adjustment of water-sealing valve directly has influence on coal tar chamber furnace pressure, to playing a key effect in working life of coal tar chamber.
At present; The structure of water-sealing valve mainly is made up of turnover panel controlling mechanism and location actuating device, but the location actuating device is the driver element real-time regulated water-sealing valve aperture of water-sealing valve, and its feedback component has the linear type edge; The linear type edge of the axle head of intelligent electricity-gas valve positioner resetting shaft feedback component in the traction lower edge of draught spring slides; Realize the accurate location of water-sealing valve aperture, but, make water-sealing valve stroke positioning error bigger because the straight line motion of the rotation of turnover panel and location actuating device exists the non-linear conversion of angle and straight line; Make water-sealing valve can not realize even electrodeless adjusting location, cause the furnace pressure control of coal tar chamber inaccurate; The special easy fatigue of draught spring frequent movement is damaged in addition, and working life is short, causes the rate of fault of water-sealing valve higher, the continuous operation that influence is produced.
Summary of the invention
The purpose of the utility model provides a kind of step-less adjustment location actuating device, overcomes the deficiency of existing technology, improves the control accuracy and the resistance to heat of location actuating device, reduces the water-sealing valve rate of fault, improves coke oven working life.
For solving the problems of the technologies described above, the technological scheme of the utility model is:
A kind of step-less adjustment location actuating device; Comprise pneumatic drive unit and control unit; Said pneumatic drive unit comprises high temperature resistant type cylinder, lock valve, pneumatic throttle, and said control unit comprises intelligent electricity-gas valve positioner and feedback component, and said feedback component is provided with the waveform chute; The axle head of intelligent electricity-gas valve positioner resetting shaft places in the chute, and said chute is the arc curve that is formed by connecting the multistage curve that the non-linear conversion of stroke and angle produces.
Said lock valve is the double-action high temperature resistant type.
Said intelligent electricity-gas valve positioner is high temperature resistant double acting positioner.
Compared with prior art, the beneficial effect of the utility model is: 1) simple for structure, volume is little, regulate easy, precision is high, has guaranteed the precision of coal tar chamber furnace pressure control, and then working life of having improved coke oven.2) high temperature resistant type lock valve and intelligent electricity-gas valve positioner have effectively improved the working life of water-sealing valve under the hot environment, have reduced the failsafe valve rate, satisfy the continuous service condition of producing.

Among the figure: the intelligent electricity-gas valve positioner resetting shaft of the intelligent electricity-gas valve positioner 4-of 1-high temperature resistant type cylinder 2-feedback component 3-lock valve 5-pneumatic throttle 6-chute 7-
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
Seeing Fig. 1, Fig. 2, is a kind of step-less adjustment of the utility model location actuating device example structure schematic representation, comprises pneumatic drive unit and control unit; Pneumatic drive unit comprises high temperature resistant type cylinder 1, lock valve 4, pneumatic throttle 5, and control unit comprises intelligent electricity-gas valve positioner 3 and feedback component 2, and feedback component 2 is provided with waveform chute 6; The axle head of intelligent electricity-gas valve positioner resetting shaft 7 places in the chute 6; Chute 6 is the arc curves that are formed by connecting the multistage curve that the non-linear conversion of stroke and angle produces, and axle head that can type electricity-gas valve positioner resetting shaft 7 slides in chute 6 freely, and is simple in structure; Accurate positioning; Reduce dynamical element, reduce production costs, improved the Security reliability.
For meeting the demands of the working life that makes water-sealing valve under the hot environment and Location accuracy, lock valve 4 is selected the double-action high temperature resistant type for use.Intelligent electricity-gas valve positioner 3 also is high temperature resistant double acting positioner.
The working principle of the utility model is: extraneous 0.5MPa work source of the gas is supplied with intelligent electricity-gas valve positioner 3; Simultaneously intelligent electricity-gas valve positioner 3 receives the input signal of 4～20mA of coke oven central control chamber; Feed back the position that high temperature resistant type cylinders 1 stretch out piston rod through feedback component 2; Intelligent electricity-gas valve positioner 3 is regulated the water-sealing valve aperture through signal fusing, thereby realizes accurately regulating the step-less adjustment of water-sealing valve control raw coke oven gas flow in the coke oven gas gathering system.
When bleed pressure was lower than setting value 0.3MPa, lock valve 4 was automatic locking, and it is motionless to make high temperature resistant type cylinder 1 remain on original position; When bleed pressure is higher than this setting value, high temperature resistant type cylinder 1 regular event, thus realize the effect of safety guarantor position.
