Description
Technical field
The present invention relates to technical field of drainage, particularly relating to one has the eccentric stifled door of pressure.
Background technology
In pipeline, rainwater and sewage are by gravitational discharge, and flow velocity is low, often has the electrodeposition substances such as silt and cause line clogging in pipeline; Deposit also can produce toxic gas corrosion pipeline, therefore needs regularly to rinse pipeline; During service conduits, need to carry out shutoff to pipeline.Traditional bias is blocked up door and according to installing the distance needing to regulate sealing plate and pipeline opening, can not be used and having limitation.
Summary of the invention
The object of the present invention is to provide one to have the eccentric stifled door of pressure, the shutoff to pipeline when can be used for service conduits, because its shutoff water level is high, flushing pipe can also be used for, and can according to installing the distance needing to regulate sealing plate and pipeline opening, flexibility is good, applies more extensive.
Technical scheme of the present invention is: one has the eccentric stifled door of pressure, comprise pipeline and the exterior wall around pipeline, described exterior wall is embedded with installing plate, described installing plate is provided with supporting seat in pipeline bilateral symmetry, rotated by axis of rotation between described supporting seat and be fixed with eccentric body, the center of gravity of described eccentric body does not overlap with center of rotation, described installing plate is fixed with the drive unit for driving axis of rotation to rotate, described eccentric body is connected with along pipeline axial apart from adjustable and corresponding with the pipeline opening sealing plate for blocking pipe away from the side of axis of rotation.
Further, described drive unit comprises oil cylinder and rocking arm, described installing plate is fixed with oil cylinder pedestal, is fixedly connected with bottom described oil cylinder with oil cylinder pedestal, and described one end is connected with cylinder piston rod, and the other end is connected with the axis of rotation of eccentric body.
Further, described eccentric body is connected with flange away from the side of axis of rotation, described flange is connected by lock bolt with sealing plate, and described flange is provided with spacing hole, and described spacing hole internal thread is connected with the first caging bolt that end abuts with sealing plate plate face.
Further, described eccentric body is arc, and described arc is connected with flange by a tubular junction away from the side of axis of rotation.
Further, described axis of rotation is connected by flat key with between eccentric body, and described axis of rotation is connected by flat key with between rocking arm.
Further, described sealing plate is provided with annular slot, in described annular slot, is bolted O-ring seal.
Further, described installing plate comprises around the pedestal mounting plate of install pipeline and is connected the oil cylinder pedestal mounting plate be positioned at outside pedestal mounting plate with pedestal mounting plate, described supporting seat is symmetricly set on pedestal, described base central is provided with pipe hole, and described pedestal is fixedly connected with pedestal mounting plate.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.In addition, if below in described each embodiment of the present invention involved technical characteristic do not form conflict each other and just can mutually combine.
As shown in figs. 1 and 4, illustrated have the eccentric stifled door of pressure, comprises pipeline 4 and the exterior wall 5 around pipeline 4, wherein the pipeline opening of pipeline 4 and horizontal plane.Described exterior wall 5 is embedded with one piece of installing plate 1, as shown in Figure 5, installing plate 1 comprise around pipeline 4 arrange annular mounting plate 2 and be connected the oil cylinder pedestal mounting plate 3 be positioned at outside annular mounting plate 2 with annular mounting plate 2.Annular mounting plate 2 is bolted an annular pedestal 15, as shown in Figure 8, the inner ring of pedestal 15 is pipe hole.This pedestal 15 bilateral symmetry is fixed with a supporting seat 9, oil cylinder pedestal mounting plate 3 is fixed with an oil cylinder pedestal 6.Oil cylinder pedestal 6 is connected with an oil cylinder 7, the bottom of oil cylinder 7 is flexibly connected by bearing pin with oil cylinder pedestal 6, and piston rod is then connected with rocking arm 8.Rotate between the supporting seat 9 of two, left and right and be fixed with an eccentric body 10, as shown in Figure 6, this eccentric body 10 is provided with axis of rotation installing hole, the two ends of eccentric body 10 are fixing with two supporting seats 9 by the axis of rotation 11 through axis of rotation installing hole, and one of them axis of rotation 11 is connected with the other end of rocking arm 8.In axis of rotation 11, axis of rotation installing hole, rocking arm all has groove, axis of rotation 11 is all connected by flat key with between rocking arm and eccentric body.Eccentric body 10 be one piece from middle part to the arc that two ends height reduces gradually, eccentric body center of gravity does not overlap with center of rotation, and axis of rotation line (i.e. the center of rotation of eccentric body) and pipeline center's axle be not on same level height.The arc of eccentric body 10 is connected with a tubular junction 12 away from the side of axis of rotation 11, and the other end of tubular junction 12 is provided with a flange 13, and tubular junction 12 is connected with one block of circular seal plate 14 by flange 13.As shown in Figures 2 and 3, flange 13 is connected by lock bolt 17 with sealing plate 14, and flange 13 is provided with spacing hole, and spacing hole internal thread is connected with the first caging bolt 18 that end abuts with sealing plate 14 plate face.Flange 13 top is also provided with a projection 20 protruding upward, projection 20 is provided with second caging bolt 19 abutted through projection 20 and with pedestal 15 surface.As shown in Figure 7, circular seal plate 14 is provided with annular slot 21, has been bolted O-ring seal 16 in annular slot 21, the cross section of sealing circle is " P " shape.The inner ring of pedestal 15 is the conical surface 23, and sealing ring 16 and the conical surface 23 are formed and seal.Sealing plate 14 external diameter is greater than the bore of pipeline, and the sealing ring on sealing plate 14 covers pipeline opening, forms soft seal to pipeline opening.
By regulating the first caging bolt 18, distance between sealing plate 14 and inclined plane is adjusted to desired location, when needs carry out shutoff to pipeline 4, the piston rod of oil cylinder 7 is moved back, and drives rocking arm 8 around central rotation, the axis of rotation 11 be connected with rocking arm 8 center rotates thereupon, thus driving eccentric body 10 to rotate, sealing ring 16 contacts with the inclined plane 23 of pipeline opening top base 15, the shutoff of shape twin conduit 4, now can carry out the maintenance of pipeline 4, also may be used for shutoff high water level.When maintenance complete/when needing to rinse pipeline, oil cylinder 7 piston rod stretches out forward, drive rocking arm 8 around central rotation, thus eccentric body 10 is upwards rotated, sealing ring leaves pipeline opening under the drive of eccentric body, and because eccentric body 10 is arc platy structure, it is without hindrance that the arc space that arc is formed makes pipeline opening open completely, then can realize the flushing of high water level to pipeline, also can realize the normal work of pipeline.
The above, be only the specific embodiment of the present invention, it should be pointed out that any those of ordinary skill in the art are in the technical scope disclosed by the present invention, the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.
