Description

Repairing device for socket type pipeline joint

Technical Field

The utility model relates to a pipeline repair, specifically say exactly that patching device is used to socket joint formula pipeline interface.

Background

The socket joint type connection of the pipe bodies is quite common, namely, a pipe head section of one pipe body is inserted into a bowl-shaped pipe mouth section of the other pipe body, the pipe diameter of the bowl-shaped pipe mouth section is slightly larger than the pipe diameter of the other pipe body, and gluing sealing or arrangement of a sealing ring is reasonably selected according to the material, the pipe diameter, the application and the performance requirements of the pipe bodies.

In the prior art, the water leakage of the pipe joint is generally repaired by adopting a Hough section, however, one end of the socket type pipe joint is of a bowl-shaped structure with a larger pipe diameter and can interfere the use of the Hough section, so that a repairing device for rapidly repairing the socket type pipe joint is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a patching device is used to socket joint formula pipe connection mouth can carry out the leaking stoppage when the pipe connection mouth appears leaking and repairs.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a patching device for socket joint formula pipeline interface, establish the sealing washer that is used for shutoff bowl form mouth of pipe on the straight tube including the cover, the sealing washer encircles the overlap joint by the sealing strip and constitutes, two half-bodies of huff ring connect the ring socket, the ring socket constitutes the cooperation of restricting the ring socket and keeping away from the interface with the pipeline that bowl form mouth of pipe place, the sealing washer is kept away from the cooperation that the joint one side set up huff formula annular pressure disk and ring socket constitute restriction socket joint formula pipeline axial separation, the both sides and the inner ring of sealing washer constitute pressfitting seal with huff formula annular pressure disk, bowl form mouth of pipe and straight tube outer pipe wall respectively.

In the above scheme, when the spigot-and-socket pipeline joint fails, the sealing ring can be effectively repaired by pressing the sealing ring at the gap between the bowl-shaped pipe orifice and the straight pipe through the half-type pressure plate.

Detailed Description

The utility model provides a patching device is used to socket joint formula pipeline interface which characterized in that: the sealing ring 10 is sleeved on the straight pipe 2 and used for plugging the bowl-shaped pipe orifice 1, the sealing ring 10 is formed by surrounding and lapping a sealing strip, the two half bodies 20 are connected into a ring socket, the ring socket and the pipe where the bowl-shaped pipe orifice 1 is located form a fit for limiting the axial separation of the ring socket, the half annular pressure plate 30 arranged on one side of the sealing ring 10 away from the interface and the ring socket form a fit for limiting the axial separation of the socket type pipe, and the two sides and the inner ring of the sealing ring 10 respectively form press fit sealing with the half annular pressure plate 30, the bowl-shaped pipe orifice 1 and the outer pipe wall of the straight pipe 2.

In the above scheme, when the spigot-and-socket pipe joint fails, when water leaks from the gap between the bowl-shaped pipe orifice 1 and the straight pipe 2, the sealing ring 10 and the press-fit sealing area between the bowl-shaped pipe orifice 1 and the straight pipe 2 can be effectively blocked, and the straight pipe 2 possibly deforms to cause untight sealing between the sealing ring 10 and the straight pipe 2, so that the press-fit sealing area formed by the sealing ring 10 and the annular pressure plate 30 can also block the water leakage from the gap between the straight pipe 2 and the sealing ring 10.

The inner ring of the ring socket forms a horn-shaped structure which is attached to the outer wall of the bowl-shaped pipe orifice 1. Thus, the shape of the ring socket is matched with the bowl-shaped pipe orifice 1 to form a slope, so that the unidirectional displacement of the pipeline relative to the ring socket along the axial direction is prevented, and the matching for limiting the axial separation is formed.

The two ends of the sealing strip are wedge-shaped inclined planes or step-shaped straight planes which are mutually overlapped. Therefore, the sealing strip can form a complete annular structure after being encircled into the sealing ring, and the fracture cannot influence the leakage stoppage effect.

The half-half-half-. This facilitates the connection of half-half huff ring 20 to annular pressure plate 30.

The periphery of the annular pressure plate 30 is provided with an annular covered edge 32, and an annular groove for accommodating the sealing ring 10 is formed between the annular covered edge 32 and the outer pipe wall of the straight pipe 2. This facilitates the accommodation of the stationary seal ring 10.

The two ends of the half bodies of the annular pressure plate 30 are provided with mutually lapped steps 33, the step surfaces of the half bodies are perpendicular to the axial direction of the annular pressure plate 30, the two half bodies of the annular pressure plate 30 form a complete annular structure through mutual attachment of the steps 33, and the mutually attached steps 33 are connected through countersunk bolts. The bolts connecting the overlapped step surfaces are countersunk bolts, so that the interference of the bolts with the pressing surfaces is avoided, and the annular pressure plate 30 formed in such a way has a complete annular surface, so that the sealing ring 10 can be uniformly pressed.
