Abstract
The utility model discloses a by-pass valve which has better sealing property and is positioned on a bypass flue in a bag type dust remover. The by-pass valve comprises a valve body arranged on the bypass flue, and a spring sealing valve plate is connected with a drive rod of a lifting air cylinder. The by-pass valve is characterized in that the spring sealing valve plate is a double-layer spring sealing valve plate composed of an upper-layer sealing plate and a lower-layer sealing plate, and a shoulder matched with the upper-layer sealing plate in the double-layer spring sealing valve plate is arranged on the inner wall of the valve body. The by-pass valve used in the bag type dust remover increases the sealing property greatly, the middle of the valve plates is communicated with the compressed air, and the fume can attain the purpose of zero leakage by sealing between the double-layer spring sealing valve plate and the gas in the middle.
Description
Technical field
The utility model relates to the sack cleaner that is mainly used to handle the flue gas that coal-burning boiler produces, and refers more particularly to the by-passing valve on the by-pass flue in this sack cleaner.
Background technology
In the sack cleaner equipment of handling fire coal boiler fume, when occur the boiler initial stage need throw oil combustion-supporting, when normally moving during situation such as unusual or boiler " four pipes " explosion of flue-gas temperature, in order to protect the filter bag of high value, in deduster, all be provided with by-pass flue, make the flue gas of temperature anomaly walk around filter bag and directly to discharge deduster by by-pass flue; Therefore, in by-pass flue, all be provided with by-passing valve usually, its structure is referring to shown in Figure 1, by-pass flue 7 is arranged between deduster air intake passage 6 and the deduster air-out passage 5, the structure of described by-passing valve mainly comprises: be installed in the valve body 4 on the by-pass flue 7, spring sealed valve plate 3 is connected with the drive rod 11 that promotes cylinder 1, during work, promote the action of cylinder 1 by two-position-five-way solenoid valve 5 controls, promote cylinder 1 and rise or descend, to open or to close by-pass flue 7 by drive rod 11 driving springs sealing valve plate 3.The shortcoming of above-mentioned by-passing valve is: the working time has been grown easy generation leakage phenomenon, and the central ash-laden gas of operation can directly enter air-out passage 5 and enter in the atmosphere like this, has reduced efficiency of dust collection thereby make smoke emissioning concentration strengthen, and has increased the weight of environmental pollution.
The utility model content
Technical problem to be solved in the utility model is: the by-passing valve on the by-pass flue in the better sack cleaner of a kind of sealing property will be provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the by-passing valve in the sack cleaner on the by-pass flue, comprise: be installed in the valve body on the by-pass flue, spring sealed valve plate is connected with the drive rod that promotes cylinder, be characterized in: the double-layer spring sealing valve plate that described spring sealed valve plate is made up of upper strata sealing plate and lower floor's sealing plate, the inwall of valve body is provided with double-layer spring and seals the convex shoulder that the lower floor's sealing plate in the valve plate matches.
The further technical scheme of the utility model is: also be provided with air inlet pipe on the inwall of valve body, air inlet pipe is connected with the closed cavity that is made of upper strata sealing plate, lower floor's sealing plate and valve body.
The utility model has the advantages that: described by-passing valve adopts double-layer spring sealing valve plate, has increased sealing property greatly.And two-layer valve plate is middle and compressed air communication, by double-layer spring sealing valve plate and intermediate gas sealing, more can make flue gas reach the purpose of zero leakage.
Description of drawings
Fig. 1 is the structural principle schematic diagram of the by-passing valve described in the background technology;
Fig. 2 is the structural principle schematic diagram of by-passing valve described in the utility model.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, by-passing valve in the described sack cleaner on the by-pass flue, comprise: be installed in the valve body 4 on the by-pass flue 8, spring sealed valve plate 3 is connected with the drive rod 11 that promotes cylinder 1, be characterized in: the double-layer spring sealing valve plate 3 that described spring sealed valve plate 3 is made up of upper strata sealing plate 31 and lower floor's sealing plate 32, the inwall of valve body 4 are provided with double-layer spring and seal the circle convex shoulder 41 that the lower floor's sealing plate 32 in the valve plate matches.And, in the present embodiment, on the inwall of valve body 4, also being provided with air inlet pipe 9, air inlet pipe 9 is connected with the closed cavity that is made of upper strata sealing plate 31, lower floor's sealing plate 32 and valve body 4.Air inlet pipe 9 is provided with operated pneumatic valve 2.
During work, promote the action of cylinder 1 and operated pneumatic valve 2 by two-position-five-way solenoid valve 5 controls.When boiler was in normal operating condition, by the control of control device, two-position-five-way solenoid valve 5 controls promoted cylinder 1 and descend by its drive rod 11 driving double-layer spring sealing valve plates 3, make itself and sealed valve body 4 tight closure reach double-layer seal.Two-position-five-way solenoid valve 5 control operated pneumatic valves 2 are opened then, Compressed Gas continues to enter in the space of the tight closure that is made of upper strata sealing plate 31, lower floor's sealing plate 32 and sealed valve body 4 by air inlet pipe 9, make gas pressure in this space greater than the ash-laden gas pressure in the by-pass flue 8, dusty gas can not pass through, and further reaches the sealing effectiveness of zero leakage.When unnormal burning situation appears in boiler; promote cylinder 1 action by control device control; make on the double-layer spring sealing valve plate 3 and move a segment distance; outlet and inlet passage 7 and 6 in the sack cleaner is interconnected by by-pass flue 8; like this; the unusual flue gas of discharging because of boiler failure will be not by the filter chamber of cleaner, and directly in sack cleaner air-out flue 6 discharge, to reach the purpose of protection cleaner.
Claims (2)
1, the by-passing valve on the by-pass flue in the sack cleaner, comprise: be installed in the valve body on the by-pass flue, spring sealed valve plate is connected with the drive rod that promotes cylinder, it is characterized in that: the double-layer spring sealing valve plate that described spring sealed valve plate is made up of upper strata sealing plate and lower floor's sealing plate, the inwall of valve body is provided with double-layer spring and seals the convex shoulder that the lower floor's sealing plate in the valve plate matches.
2, by-passing valve according to claim 1 is characterized in that: also be provided with air inlet pipe on the inwall of valve body, air inlet pipe is connected with the closed cavity that is made of upper strata sealing plate, lower floor's sealing plate and valve body.
