Description

Technical Field

[0001] This utility model relates to the field of PVC drainage pipe repair technology, specifically a PVC drainage pipe sealing and repair device. Background Technology

[0002] PVC drainage pipes are made primarily from sanitary-grade (PVC) resin, with the addition of appropriate amounts of stabilizers, lubricants, fillers, and colorants. They are produced through extrusion molding using a plastic extruder and injection molding using an injection molding machine. The process involves cooling, curing, shaping, inspection, and packaging to complete the production of pipes and fittings. Drainage pipes may break during sewage discharge, requiring repair of the broken ends. The break divides the drainage pipe into a first drainage pipe and a second drainage pipe. The traditional repair process involves first closing the valve upstream of the first drainage pipe, and then repairing both the first and second drainage pipes once there is no sewage flow in the first drainage pipe.

[0003] Currently, repairing PVC drainage pipes is quite complex, and adjusting the repair length is difficult, resulting in low efficiency in sealing and repairing PVC drainage pipes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a PVC drainage pipe sealing and repair device, which solves the problems mentioned in the background art, such as the complexity of repairing PVC drainage pipes and the difficulty in adjusting the repair length, resulting in low efficiency in sealing and repairing PVC drainage pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PVC drainage pipe sealing and repair device, comprising a first drainage pipe, a second drainage pipe, and a connector, wherein an inner sealing element is fixedly installed on the outer surface of the connector, and the outer surface of the inner sealing element is sealed and fitted with the inner wall of the first drainage pipe and the second drainage pipe, and two outer sealing seats are threadedly connected to the outer surface of the connector, and the two outer sealing seats are sealed and fitted with the outer surface of the first drainage pipe and the second drainage pipe.

[0006] Preferably, both outer sealing seats have a bayonet on their outer surfaces, and the outer surfaces of the first drain pipe and the second drain pipe are provided with a semi-circular reinforcing plate. The outer surfaces of both semi-circular reinforcing plates are fixedly installed with a locking block, and the locking block is sealed and engaged with the bayonet.

[0007] Preferably, the outer surfaces of the card block and the card slot are uniformly coated with 0.2 mm of PVC waterproof adhesive, and the outer surface of the outer sealing seat is provided with reinforcing bolts. The semi-circular reinforcing plate and the outer sealing seat are fixedly connected by the reinforcing bolts.

[0008] Preferably, the first drain pipe and the second drain pipe are fixedly connected through the inner sealing member, the outer surfaces of the two outer sealing seats are fitted together, and the two outer sealing seats are disposed on both sides of the connector.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This PVC drainage pipe sealing and repair device seals the first drainage pipe with the connector and the inner seal, and then controls the two outer sealing seats to rotate spirally on the outer surface of the connector to adjust the repair range. This allows the two outer sealing seats to work with the connector and the inner seal to seal and repair the first and second drainage pipes from the inside and outside, thereby facilitating the adjustment of the repair length and improving the efficiency of PVC drainage pipe sealing and repair.

[0011] 2. This PVC drainage pipe sealing and repair device adjusts the position of the first and second drainage pipes on the outer surfaces of the two outer sealing seats, and seals the semi-circular reinforcing plate with the outer sealing seat under the sealing engagement of the clip and the slot, thereby achieving the effect of facilitating rapid repair and making the repair operation convenient.
