Abstract
The utility model relates to a lift valve for blow vents of dust-collectors, which is used for blow pipelines of industrial dust-collectors. The utility model comprises an air cylinder (1), a supporting base (2), a connecting rod (3), a sealing device (4), a sealing ring (5), a valve plate (6), a box body (7), a blow vent (8) and an air inlet (9). The air cylinder (1) and the valve plate (6) are vertically arranged, and the connecting rod (3) and the center of the valve plate are vertically connected. When air flow passes through, the resistance loss is zero, the air flow in the pipeline is stable, the power consumption of the air cylinder is little, and the valve is better than a butterfly valve and a flap valve. The utility model has the advantages of simple structure, reliable performance and long service life.
Description
The application relates to the full-open type airtight valve, particularly is used for the valve of industrial dedusting device relief opening.
Deduster relief opening valve is the important composition part of dusting apparatus, and it is closed when deashing, opens during exhaust, and its working condition directly influences the operation and the dust removal efficiency of deduster.
The valve of industrial dedusting device relief opening generally uses butterfly valve or Flap valve at present, the valve plate of butterfly valve is horizontal axial direction in valve body when standard-sized sheet, the loss of valve body (especially large-diameter butterfly valve) internal resistance can reach 10%～30% in long-term using process, thereby fan energy consumption is increased, and cause air-flow instability in the pipe; Flap valve valve plate in the opening and closing process all moves along a curved path, and this is because cylinder need remake by power arm and resistance arm and be used for valve plate, so the cylinder power loss is big, and it is with a toll of 20%～40%.
The purpose of this utility model designs a kind of poppet valve in order to overcome above-mentioned shortcoming exactly, and the valve body internal resistance is zero when making exhaust, and steady air current in the pipeline, cylinder power loss are zero or minimum.
For this reason, the utility model is that cylinder is vertical with valve plate, and connecting rod is connected with the valve plate central vertical, drives valve plate and moves up and down with switch valve.
For improving the sealing of valve, hollow rubber seal is adopted in the valve plate sealing.Because cylinder power vertically acts on the valve plate center by connecting rod, seal ring is stressed evenly.
For the heavy caliber valve, evenly stressed for guaranteeing valve plate, be preferably in the valve plate center and connect a little flange with bolt, connecting rod is connected with the valve plate center by little flange.
The utility model is compared with butterfly valve, Flap valve, because the former is that cylinder passes through the vertical cistron valve plate of connecting rod center, makes the parallel lifting of valve plate, therefore can make full use of the power of cylinder.Behind opening of valves, valve plate can all rise on the valve body, and the air-flow in the pipeline can pass through valve in non-resistance ground, and the loss of valve body internal resistance was zero when promptly gas was by valve, makes the interior air-flow of pipeline keep stablizing.In addition, saved power arm, resistance arm, running shaft simplifies the structure.
The application is further specified as follows with drawings and Examples.
Fig. 1 is a generalized section of the present utility model.
Among the figure, 1-cylinder: 2-cylinder saddle; The 3-connecting rod; The 4-seal arrangement; The 5-seal ring; The 6-valve plate; 7-valve casing; The 8-relief opening; The 9-suction port; The little flange of 10-.
Embodiment: a deduster relief opening poppet valve that is used for industrial dedusting device exhaust duct comprises cylinder 1, cylinder saddle 2, connecting rod 3, seal arrangement 4, seal ring 5, valve plate 6, valve casing 7, relief opening 8, suction port 9.Cylinder 1 is above cylinder saddle 2, and the latter is connected with valve casing 7.Cylinder 1 and valve plate 6 vertical installations, the connecting rod 3 that moves on cylinder-bore axis is connected with the valve center.Its Placement can directly be welded connecting rod and valve plate; For large bore valves, stressed evenly so that valve closing is good for keeping valve plate, the Placement of this moment preferably adopts little flange, is about to little flange 10 usefulness bolts and is connected with the valve plate center, and connecting rod 3 inserts the center of little flange 10 again and is welded to each other.Suction port 9 is connected with the deduster relief opening.
Hollow rubber seal 5 is contained in the periphery of valve plate 6 bottoms, with clip it is stuck in the valve plate edge and gets final product.
During the deduster deashing, the power of cylinder 1 is closed suction port 9 by the center promotion valve plate that connecting rod 3 acts on valve plate 6.Because the effect of seal ring is closed good.During exhaust, valve plate 6 is carried to the valve body upper end, and pipe gas flow enters valve body by suction port 9 and discharge smoothly by relief opening 8 on non-resistance ground.
Claims (4)
1, deduster relief opening poppet valve, comprise cylinder (1), cylinder saddle (2), connecting rod (3), seal arrangement (4), valve plate (6), valve casing (7), relief opening (8) and suction port (9), it is characterized in that cylinder (1) is vertical with valve plate (6), connecting rod (3) is connected with the central vertical of valve plate (6).
2,, it is characterized in that the center welding of connecting rod (3) and valve plate (6) according to the said poppet valve of claim 1.
3, according to the said poppet valve of claim 1, it is characterized in that connecting rod (3) inserts the center of little flange (10) and is welded to each other, little flange (10) is connected by the center of bolt with valve plate (6).
4, according to claim 1 to 3 any one, it is characterized in that the lower periphery of valve plate (6) is equipped with hollow rubber seal (5).
