Abstract
The invention discloses a quick damper. The quick damper comprises a hollow pipe and a damping plug, wherein the hollow pipe presents a disc-ring shape except for two end portions; one end of the hollow pipe is used for connecting a pressure-measuring point; the other end of the hollow pipe is provided with the damping plug therein; the damping plug is provided with a through hole along the axial direction of the hollow pipe; and the end provided with the damping plug of the hollow pipe is used for connecting a transmitter. The damper employs a physical damping principle to eliminate filtering wave directly for the pressure-measuring point, overcomes interference effectively, and is not only suitable for the automatic adjustment of high-quality pressure and differential pressure in coking and coal chemical industries but also suitable for adjustment objects with many interference sources and high requirements for adjusting quality in petroleum and chemical industries.
Description
Technical field
The present invention relates to a kind of rapid damping device.
Background technology
Coke oven collecting main pressure control is important technical parameters during coke oven is produced.Aborning, the coal oven dithio-gas collecting main pressure is regulated automatically and is vulnerable to various pulsation undesired signals, and some undesired signal has just surpassed the adjusting SP, and dried scratching causes system to be difficult to normal operation.
Coke oven collecting main pressure will be realized the high precision in control of 80 ± 10Pa, and certain degree of difficulty is arranged.Some coke-oven plant adopts electric damper DFZ-1000 through repeatedly technological transformation; Regulation system so far still can not steady running, and reason is the dried signal of scratching of pulse of 4-20mA in the electrical deoscillator damping transmitter output fast, puts weak point damping time; The dried signal of scratching is filtered not fall; Lengthen damping time a bit, damping lags behind, and causes regulation system normally not move.Existing pressure damper not only can't be applicable to coking, the high-quality pressure of Coal Chemical Industry, and differential pressure is regulated automatically, can't be applicable to that also oil, the dried source of scratching of chemical industry are many, the demanding controlled plant of regulation quality.
Summary of the invention
The object of the present invention is to provide a kind of rapid damping device; This deoscillator uses the principle of physical damper that pressure point is directly removed filtering; Effectively overcome interference, this rapid damping device not only is suitable for coking, and the high-quality pressure of Coal Chemical Industry, differential pressure are regulated automatically; Be applicable to that also oil, chemical industry interfering source are many, the demanding controlled plant of regulation quality.
In order to realize above purpose, technical scheme of the present invention is following: the rapid damping device is characterized in that comprise hollow tube and damping plug, hollow tube other part except two ends is the disk ring shape; One end of hollow tube is used to connect the pressure point, and the pipe inside of the other end is provided with damping plug; Damping plug along hollow tubular shaft to having through hole; The end that hollow tube is provided with damping plug is used to connect transmitter.
Described damping plug adopts the stainless material manufacturing to form.
Described hollow tube adopts the above plastic material of withstand voltage 1.0Mpa to be made.
The external diameter 6mm of described hollow tube, thickness of pipe 1mm.
The invention has the advantages that: the present invention puts direct filtering with the principle of physical damper to pressure, has overcome dried scratching effectively fast; Realized high-precision automatic control; This rapid damping device not only is suitable for coking, the high-quality pressure of Coal Chemical Industry, and differential pressure is regulated automatically; Be applicable to that also oil, the dried source of scratching of chemical industry are many, the demanding controlled plant of regulation quality.

Fig. 3 is the sectional view of A part among Fig. 2.
Fig. 4 is the synoptic diagram that the present invention is applied to coke(oven)gas effuser electric butterfly valve single-stage regulation system.
Wherein, the 1st, damping plug; A partly is the end that the rapid damping device is provided with damping plug.
Embodiment
Below in conjunction with accompanying drawing specific embodiment of the present invention is further specified.
Deoscillator of the present invention is in use without power supply, source of the gas, carries out filtering (in 0.1 second) by the resistance device with the speed of 340 meters of velocities of sound/speed, and the direct level and smooth pulsating pressure undesired signal of damping has realized that pressure regulates automatically.
As shown in Figure 1, the principle of work of rapid damping device of the present invention: hollow tube is earlier to the thick damping of pressure signal, and damping plug is realized accurate damping to pressure signal once more then, connects the signal of transmitter output 4-20mA at last.
Rapid damping device of the present invention comprises hollow tube and damping plug, and hollow tube other part except two ends is the disk ring shape; One end of hollow tube is used to connect the pressure point, and the pipe inside of the other end is provided with damping plug; Damping plug along hollow tubular shaft to having through hole; The end that hollow tube is provided with damping plug is used to connect transmitter.
Wherein, hollow tube adopts the above plastic material of withstand voltage 1.0Mpa to be made; Damping plug adopts stainless material to make; The external diameter 6mm of hollow tube, thickness of pipe 1mm; Damping plug adopts stainless tube material manufacturing to form; The length of hollow tube is 6 meters.
Among Fig. 4, two coke oven pneumatic troughs are communicated with into as a whole with the weldless steel tube of DN250, and transmitter pressure point has promptly been got the common pressure of two coke ovens on the weldless steel tube of DN250.Two original cover regulation systems become a cover, reduced maintenance workload, and regulation system realized ± and the pressure of 10Pa regulates stable and reliable operation.
Rapid damping device of the present invention not only is suitable for coking, and the high-quality pressure of Coal Chemical Industry, differential pressure are regulated automatically, is applicable to that also oil, the dried source of scratching of chemical industry are many, the demanding controlled plant of regulation quality.
