Abstract
The utility model designs a compensation type plugging device aiming at the problem that the traditional plugging device is easy to leak at the arc rubber ring part. Through setting up the triangular block at circular arc part, under the condition that the staple bolt is mutually hugged mutually through the bolt, triangular block deformation increases pressure and compensation volume to circular arc part to further strengthen the leakproofness of circular arc part. The compensation type plugging device comprises a pair of hoops, a sealing ring and a fastening piece, wherein a mounting groove is formed along each hoop, the sealing ring is adhered in the mounting groove and is divided into two parts, a first part is arranged along the straight edge of each hoop, a second part is arranged along the circular arc edge of each hoop, and triangular block protrusions are arranged on the junction points of the first part and the second part; the first portion, the second portion and the triangular block are integrally formed.
Description
Technical Field
The utility model relates to a plugging connection device of a water transmission pipeline, in particular to a compensation type plugging device.
Background
The leakage blocking principle is to process a clamp according to the shape of a pipeline and a pipe fitting and the size of a leakage point, and the clamp completely covers the whole section of corroded or thinned pipeline into a cavity. However, the conventional plugging device is easy to cause incomplete occlusion on the rubber of the arc interface, so that the problem of liquid leakage is caused, which leads to the extension of maintenance work and also requires additional equipment.
Disclosure of Invention
The utility model designs a compensation type plugging device aiming at the problem that the traditional plugging device is easy to leak at the arc rubber ring part. Through setting up the triangular block at circular arc part, under the condition that the staple bolt is mutually hugged mutually through the bolt, triangular block deformation increases pressure and compensation volume to circular arc part to further strengthen the leakproofness of circular arc part.
The compensation type plugging device comprises a pair of hoops, a sealing ring and a fastening piece, wherein a mounting groove is formed along each hoop, the sealing ring is adhered in the mounting groove and is divided into two parts, a first part is arranged along the straight edge of each hoop, a second part is arranged along the circular arc edge of each hoop, and triangular block protrusions are arranged on the junction points of the first part and the second part; the first portion, the second portion and the triangular block are integrally formed.
Preferably, the triangular block is a right triangle, wherein a first side of the right angle side is connected with the second part, and the other side of the right angle side is tangent to a circle where the second part is located;
the acute angle formed by the bevel edge and the first edge is 15-30 degrees.
Preferably, the thickness of the seal ring is 3 times the depth of the mounting groove.
Preferably, the inner arc of the second portion is provided with a groove for increasing friction.
The utility model has the beneficial effects that: through increasing the triangular block and making the staple bolt after pressing from both sides tightly, can pass through the second part of triangular block's volume compensation sealing washer to strengthen holistic sealed effect, thereby avoid the problem of the second part weeping of sealing washer.

FIG. 2 is a mating view of the triangular block of the present utility model in installation;
FIG. 3 is a diagram of the mounting location of a triangle block of the present utility model;
in the figure: 1. The anchor ear, 2, triangular block, 3, second part.
Detailed Description
The technical scheme of the utility model is further specifically described below through specific embodiments and with reference to the accompanying drawings.
Examples
The utility model provides a compensation type plugging device, includes a pair of staple bolt 1, two sealing washer and three fastener, is provided with the mounting groove along the staple bolt as shown in figure 1, and the sealing washer glues and establishes in the mounting groove, and the sealing washer divide into two parts, is the first part along the straight flange setting of staple bolt, is the second part along the setting of staple bolt circular arc limit, is provided with the triangular block on the juncture of first part and second part; the first part, the second part 3 and the triangular block are integrally formed.
One hoop is provided with at least 2 first parts and 2 second parts which are alternately connected to form a sealing ring.
When the two anchor clamps are matched, the sealing rings on the first part are mutually matched in a fit and butt joint way, and the sealing rings on the second part are matched on the clasped pipeline.
As shown in fig. 2 and 3, the triangular block 2 is a right triangle, in which the triangular block is deformed by extrusion, and in which a first side of the right-angle side is connected to the second portion, and the other side of the right-angle side is tangent to a circle in which the second portion is located.
The acute angle formed by the oblique side and the first side as shown in fig. 2 is 30 deg..
The thickness of the seal ring as shown in fig. 2 is 3 times the depth of the mounting groove.
The inner circular arc of the second part is provided with a groove which is used for increasing friction force.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
