Description
Technical field
The utility model relates to a kind of seal valve.
Background technique
At present, in big-and-middle-sized flue gas pipeline, generally use Flap valve, the prepackage such as push-pull valve valve, and this kind equipment cannot meet the requirement of dedusting kind equipment to sealing and service condition.In deduster running, sealed valve should adapt to washing away of high-temperature flue gas, gathering of flue dust, also will ensure, in switch uses frequently, to remain good sealability.There are problems in existing Flap valve and push-pull valve: first in deduster, and motor cannot run under hot environment (between 130-170 degree Celsius); Secondly, dust accumulates in sealing position, directly affects sealing effect; Again, when seal valve frequently uses, the rapid aging distortion of sealing joint strip, cannot ensure sealability.
Summary of the invention
For solving above Problems existing, the utility model provides a kind of dedusting Integral pneumatic seal valve of good seal performance, and for achieving the above object, the utility model is achieved through the following technical solutions:
Comprise cylinder, guide rod, enclosing housing, upper valve plate, lower valve plate, compressed air hose and sealed pipe, the bottom of sealed pipe is fixed on enclosing housing, the top of sealed pipe and the bottom of cylinder fix, the top of enclosing housing has circular hole, the aperture of this circular hole is identical with the internal diameter of sealed pipe, and this circular hole is positioned at immediately below sealed pipe, the inside of sealed pipe is connected with the inside of enclosing housing; Upper valve plate and lower valve plate are positioned at the inside of enclosing housing, upper valve plate and lower valve plate are be the discoideus of horizontal positioned, the diameter of upper valve plate is slightly larger than the diameter of lower valve plate, and there is between them a fixed gap, the top of guide rod is located in sealed pipe, and the lower end of guide rod upper end and cylinder is fixed, and the bottom of guide rod is positioned at enclosing housing, and lower end of the guide rod and upper valve plate and lower valve plate fix, the middle part of guide rod is fixed with round sealed pad; It is stepped circular tube wall bottom enclosing housing, the circular pipe wall internal diameters being positioned at downstairs equals the plate footpath of lower valve plate, its tube wall is fixed with silica gel closed loop I, the circular pipe wall internal diameters being positioned at ladder equals the plate footpath of valve plate, its tube wall is fixed with silica gel closed loop II, the remaining part of enclosing housing is square tube wall, and its tube wall diameter equals the plate footpath of valve plate; When sealing valve cuts out, the plate edge of upper valve plate is close to silica gel closed loop I, the plate edge of lower valve plate is close to silica gel closed loop II, round sealed pad is positioned at bottom sealed pipe, and its edge is close on the inner tubal wall of sealed pipe, compressed air hose inserts in the left and right sidewall of enclosing housing respectively, and its outlet is on the position of inner tubal wall between valve plate and lower valve plate.
The utility model adopts double-deck valve plate to seal, and seal element adopts high temperature silicon adhesive tape (can below 500 degrees Celsius Long-Time Service); When valve closing, injecting compressed air between double-deck valve plate, makes seal space keep barotropic state, prevents ash-laden gas from entering seal space, and purge the flue dust entered; Adopt cylinder as actuator, by the opening and closing of pressurized air band movable valve, in conjunction with the seal element of high-temperature silica gel material, change and be originally rigidly sealed into soft sealing, make double-deck valve plate be in the excessive deformation state of appropriateness all the time, enhanced leaktightness effect simultaneously.
The utility model can not only adapt to hot operation environment, effectively prevents dust from gathering, and can frequently open, and does not affect sealability, while ensureing good sealing effect, adds working life, and structure is simple, widely applicable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As depicted in figs. 1 and 2, the bottom of sealed pipe 7 is fixed on enclosing housing 3, the top of sealed pipe 7 and the bottom of cylinder 1 fix, the top of enclosing housing 3 has circular hole, the aperture of this circular hole is identical with the internal diameter of sealed pipe 7, and this circular hole is positioned at immediately below sealed pipe 7, the inside of sealed pipe 7 is connected with the inside of enclosing housing 3; Upper valve plate 4 and lower valve plate 5 are positioned at the inside of enclosing housing 3, upper valve plate 4 and lower valve plate 5 are for being the discoideus of horizontal positioned, the diameter of upper valve plate 4 is slightly larger than the diameter of lower valve plate 5, and there is between them a fixed gap, the top of guide rod 2 is located in sealed pipe 7, and the lower end of guide rod 2 upper end and cylinder 1 is fixed, and the bottom of guide rod 2 is positioned at enclosing housing 3, and guide rod 2 lower end and upper valve plate 4 and lower valve plate 5 fix, the middle part of guide rod 2 is fixed with round sealed pad 8; It is stepped circular tube wall bottom enclosing housing 3, the circular pipe wall internal diameters being positioned at downstairs equals the plate footpath of lower valve plate 5, its tube wall is fixed with silica gel closed loop I 9, the circular pipe wall internal diameters being positioned at ladder equals the plate footpath of valve plate 4, its tube wall is fixed with silica gel closed loop II 10, the remaining part of enclosing housing 3 is square tube wall, and its tube wall diameter equals the plate footpath of valve plate 4.
When sealing valve cuts out, cylinder 1 drive guide rod 2 and upper valve plate 4, lower valve plate 5 bottom enclosing housing 3 both flue gas inlet move, when reaching cylinder 1 stroke, mobilely to stop.The plate edge now going up valve plate 4 is close to silica gel closed loop I 9, and the plate edge of lower valve plate 5 is close to silica gel closed loop II 10, and round sealed pad 8 is positioned at bottom sealed pipe 7, and its edge is close on the inner tubal wall of sealed pipe 7, and then closes flue gas inlet.Compressed air hose 6 inserts in the left and right sidewall of enclosing housing 3 respectively, and its outlet is on the position of inner tubal wall between valve plate 4 and lower valve plate 5.Pressurized air is entered in the confined space of upper valve plate 4 and lower valve plate 5 formation by compressed air hose 6, forming relatively high pressure, preventing because sealing the improper smoke spillage caused.
When seal valve is opened, stop compressed-air actuated input, cylinder 1 promotes, drive guide rod 2 and move up with upper valve plate 4, lower valve plate 5, Open valve, allowing flue gas to pass through, due to closing of round sealed pad 8 pairs of sealed pipe 7 tops, make flue gas can not from sealed pipe 7 internal leakage.
