Description
Technical field
Control assembly---the bypass valve of by-pass ventilation when the utility model relates to large-scale sack cleaner self-protection relates in particular to a kind of large-scale sack cleaner with bivalve plate integrated bypass valve.
Background technology
Large-scale sack cleaner is beginning extensive use aspect the processing high-temperature flue gas at present.But when the gas flow temperature that enters large-scale sack cleaner is lower than dewfall point or be higher than the filter bag limit value, can the safe operation of large-scale sack cleaner itself be constituted a threat to, must have a kind of by-pass ventilation parts to ensure the safe operation of deduster self.The large-scale sack cleaner by-pass ventilation that current China uses adopts two single valve plate valves mostly with valve.This single valve structure is little, and maintenance is inconvenient, and steel quantity consumption is big.
Summary of the invention
The purpose of this utility model is to disclose a kind of novel turnover wind control assembly that is used for large-scale sack cleaner, a kind of large-scale sack cleaner bivalve plate integrated bypass valve, the use of this device, can stop the existing by-pass ventilation control assembly of large-scale sack cleaner fully and adopt two existing above-mentioned defectives of single valve, the large-scale sack cleaner of the large-scale cloth that can reach a high temperature is handled the requirement of high temperature, high flow capacity flue gas.
The technical solution of the utility model is: a kind of large-scale sack cleaner bivalve plate integrated bypass valve, comprise cylinder, housing, valve plate, cylinder push-rod, demarcation strip, air inlet and air outlet, demarcation strip is divided into housing, following two air chambers, cylinder is installed in housing top, cylinder push-rod top connects cylinder, the bottom connects valve plate, air inlet is arranged on the chamber, air outlet is arranged on down the chamber, described large-scale sack cleaner adopts the integrated layout of bivalve plate with bivalve plate integrated bypass valve, two valve plates are set in the valve body, and valve body top is provided with two cylinders, and two cylinders are realized opening and closing simultaneously by the signal of sharing same sensor.Two valve plate holes are set on the described demarcation strip, between two valve plate holes reinforcement are set one.Weld back-up ring around the described valve plate hole, the rubber asbestos packing is trapped among outside the back-up ring, and anchor ear is fixed on back-up ring with rubber asbestos packing banding and places outward.
The beneficial effects of the utility model are: large-scale sack cleaner connects aftershaping with the valve body of bivalve plate integrated bypass valve by the roll of steel plate pressure welding, has enough rigidity intensity, can allow two shared bypass valve cylindrical shells of bypass valve like this, compare and adopt two single valves, well saved material, and it is handsome in appearance, after valve body fuses, horizontal direction is not isolated, increased the space that maintenance (maintenance) is installed, because air-flow is free uniform, guaranteed that two cylinders keep roughly suitable load, guarantee the stability of work.Work as opening of valves, air-flow enters the chamber from air inlet, and enters down the chamber by the valve plate hole, is gone out by air outlet.The utlity model has high-air-tightness, operation (maintenance) is convenient, and characteristics such as long service life have especially adopted the integrated layout of bivalve plate, and its ability of handling air quantity significantly improves.

Among the above figure: 1. cylinder, 2. housing, 3. cylinder push-rod, 4. valve plate, 5. back-up ring, 6. rubber asbestos packing, 7. anchor ear, 8. air inlet, 9. air outlet, 10. chamber, 14. times chambers on demarcation strip, 11. reinforcements, the 12. valve plate holes, 13.
The specific embodiment
Shown in Fig. 1～4, the large-scale sack cleaner of the utility model bivalve plate integrated bypass valve, comprise cylinder 1, housing 2, valve plate 4, cylinder push-rod 3, demarcation strip 10, air inlet 8 and air outlet 9, demarcation strip 10 is divided into upper and lower two air chambers with housing, promptly go up chamber 13 and following chamber 14 cylinders 1 and be installed in housing 2 tops, cylinder push-rod 3 tops connect cylinder 1, and the bottom is connected and installed valve plate 4.The shape of air inlet 8, air outlet 9 is decided because of the dust remover air duct structure, air inlet 8 is arranged on chamber 13, air outlet 9 is arranged on down chamber 14, described large-scale sack cleaner adopts the integrated layout of bivalve plate with bivalve plate integrated bypass valve, two valve plates are set in the valve body, valve body top is provided with 1, two cylinder of two cylinders 1 and realizes opening and closing simultaneously by the signal of sharing same sensor.Be provided with on the described demarcation strip 10 between 12, two valve plate holes 12, two valve plate holes reinforcement 11 is set one.Weld back-up ring 5 around the described valve plate hole 12, rubber asbestos packing 6 is trapped among outside the back-up ring 5, and anchor ear 7 is fixed on back-up ring 5 outer placing with rubber asbestos packing 6 bandings.
When the deduster nominal situation moved, cylinder push-rod extended, and promoted valve plates 4 by cylinder push-rod 3 and moved down, and touched rubber asbestos packing 6 around the valve plate 4, along with the cylinder push-rod continuation is descending, till valve plate 4 seals with rubber asbestos packing 6 all around.When the gas flow temperature that enters large-scale sack cleaner is lower than dewfall point or be higher than the filter bag limit value, the flue-gas temperature sensor will send signal to central processing unit, cylinder 1 work this moment, it is up that cylinder push-rod drives valve plate 4, air communication is crossed valve plate hole 12 and is entered 2 times chambers of housing, and discharge by air outlet 9, just the flue gas that enters before the deduster filter chamber is heated or cooling measure then.Be unlikely in that deduster is inner when forming dewfall or burning out filter bag etc. flue-gas temperature, cylinder 1 work, it is descending that cylinder push-rod drives valve plate 4, closes fully until valve plate 4, and this moment, flue gas entered the deduster filtration system again.Like this, the filter bag of deduster has just effectively been avoided dewfall or has been burnt out, and has well protected the safe operation of large-scale sack cleaner self.
