Abstract
The invention provides an air volume balancer applicable to industrial ventilation and dust removing systems such as metallurgy, mine, electric power, cement, etc.. The air volume balancer consisting of a valve body, a transmitting device, an inserting plate connected with the transmitting device and extended inside the valve body, an anti-wear liner plate is arranged on an inner wall of the valve body corresponding to the lower part of the inserting plate, the anti-wear liner plate is in seal combination with the inserting plate when the inserting plate is in completely closed state. When being used, the air volume balancer of the invention can change a flow area through the up and down movement of the inserting plate to regulate the flow, therefore, when a valve is in completely open state, the inserting plate is outside the valve body to avoid the flow resistance caused by a valve plate blocking the air flow; meanwhile, turbulent flow can not be produced as no blocking exists, therefore, straight linear flow flows inside the valve body to greatly reduce noise. Besides, as the anti-wear liner plate is arranged on the inner wall of the valve body, thus reducing the adhesion of dusts, guaranteeing cleanness, smoothness and non-dust accumulation of the air volume balancer of the invention and further reduces noise.
Description
Technical field
The present invention relates to a kind of device of regulating the dusty gas flow equilibrium, especially a kind of blast balance apparatus that is applicable in the industrial ventilation dust pelletizing systems such as metallurgy, mine, electric power, cement.
Background technology
In dust pelletizing system, the balance adjustment of dirt throughput is one of key link of decision dust removing effects.Traditional dirt controlled atmosphere regulating device adopts light-duty butterfly valve, the structures shape of butterfly valve reach the purpose of regulating flow by valve plate anglec of rotation mode, even valve plate still was positioned at the valve body middle position when aperture was maximum, this has not only formed big flow resistance, and can produce turbulent flow and make a noise.Owing to contain dust in dedusting gas, this washes away butterfly valve itself and cleaning shaft formation simultaneously.Traditional solution is to adopt the method for change butterfly valve materials such as abrasion-resistant stee, pile-up welding hard alloy, but effect and not obvious.
At an above difficult problem, the inventor starts with from the flow direction that solves dirt gas, has invented blast balance apparatus.
Summary of the invention
The technical problem that solves
The objective of the invention is provides the blast balance apparatus that a kind of flow resistance is little, noise is low at above-mentioned the deficiencies in the prior art.
Technical scheme
For achieving the above object, the present invention adopts following technical scheme:
Blast balance apparatus of the present invention comprises valve body and the transmission device that is installed on the valve body, wherein also comprise and be connected with transmission device and extend into plate in the valve body, described valve interior wall has installed abrasion-proof backing block corresponding to the plate lower end part, when plate was in buttoned-up status, plate and abrasion-proof backing block were sealed and matched.
The bottom of described plate is the circular arc identical with the valve interior wall shape, and abrasion-proof backing block equates with plate bottom arc length along the valve body circumferential length.
Described abrasion-proof backing block is the poly-tetrafluoro liner plate of high density.
Described transmission device comprises the housing that is fixed on the valve body, be rotatably installed in leading screw in the housing, with the leading screw nut engaged, described plate is connected on this nut.
Described housing is provided with observation window.
Described housing is provided with valve opening position dictator.
Described being provided with the valve body link position on housing blown ash mouthful, blows in the ash mouthful to be equipped with and to blow tepetate.
Beneficial effect
The advantage and the good effect of blast balance apparatus of the present invention are: among the present invention, be connected with transmission device and extend into plate in the valve body owing to be provided with, during use by plate move up and down the change circulation area, carry out Flow-rate adjustment.Like this, when valve complete opening state, plate is positioned at outside the valve body, produces flow resistance with regard to having avoided because of the valve plate barrier air; Simultaneously, can not produce turbulent flow because do not stop yet, thus mobile in valve body be straightway linear flow, thereby reduced noise significantly.In addition, owing to be provided with abrasion-proof backing block, reduced the adhesive force of dust at valve interior wall, guaranteed blast balance apparatus cleaning of the present invention, smoothly, dust stratification not, further eliminated noise.

The specific embodiment
Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1 and Figure 2, blast balance apparatus of the present invention comprises valve body 1, is installed in the transmission device on the valve body 1, and the plate 2 that is connected and can moves up and down with transmission device.Installed abrasion-proof backing block 3 at valve body 1 inwall corresponding to plate 2 lower end parts.When plate 2 was in buttoned-up status, plate 2 was sealed and matched with abrasion-proof backing block 3.Abrasion-proof backing block 3 can be the poly-tetrafluoro liner plate of high density, perhaps other surface cleanings, level and smooth wear-resisting again liner plate.Among the present invention, valve body 1 is columnar, and the bottom of plate 2 is and the identical circular arc of tubular valve body shape that abrasion-proof backing block 3 equates with plate 2 bottom arc length along the valve body circumferential length, also can be longer than plate 2 bottom arc length slightly.
Transmission device among the present invention comprise the housing 4 that is fixed on the valve body 1, by bearing be rotatably installed in the housing 4 leading screw 5 and with leading screw 5 nut engaged 6.The end that leading screw 5 stretches out housing 4 is equipped with handle 8.Described plate 2 top ends are fixedly connected on this nut 6.Be fixed with fixed head 10 with relative position place, plate 2 both sides in the valve body 1, be fixed with guide rail 9 on the fixed head 10.Plate 2 moves up and down along described guide rail 9.
Described housing 4 is provided with observation window 7, is used to observe the valve body internal state, also as access hole, maintains easily simultaneously.Also be provided with valve opening position dictator 13 on the housing 4.Transmission device among the present invention can also adopt other versions such as pneumatic, electronic.On housing 4, be provided with and blow ash mouthful, blow in the ash mouthful and be equipped with and blow tepetate 12 with valve body 1 link position.When plate moves up and down for more than 2 time, on housing 4, accumulate dust easily with valve body 1 junction, to open and blow tepetate 12, the dust that can will locate cleans out, and is very convenient.Blow the ash mouth simultaneously and also can be used as access hole.
As Fig. 3, Fig. 4 and shown in Figure 5, when using blast balance apparatus of the present invention, adjust handle 8, the leading screw 5 of fixedlying connected with handle 8 rotates, driving nut 6 moves up and down, further drive the plate 2 of fixedlying connected and move up and down, can change circulation area, reach the purpose of regulating flow along guide rail 9 with nut 6.
Blast balance apparatus compact conformation of the present invention, volume are little, in light weight, have replaced original light-duty butterfly valve, have not only obtained extraordinary effect, and have reduced cost, have prolonged the life-span, have eliminated noise.
More than be preferred forms of the present invention, according to content disclosed by the invention, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into the scope of protection of the invention.
