The utility model discloses an electric smelting sleeve for rush repair, which comprises an electric smelting sleeve body and a sleeve shell, wherein a step structure is arranged in the electric smelting sleeve body, sealing rings are arranged on two sides of the step structure and are positioned at the end parts of pipes to be connected, O-shaped ring grooves are formed in the inner surfaces of two ends of the electric smelting sleeve body, O-shaped rings are arranged in the O-shaped ring grooves, and the sleeve shell is sleeved on the electric smelting sleeve body. According to the utility model, the sealing of the inside of the pipeline is realized through the sealing ring, and the sealing of the outer surface of the pipeline is realized through the O-shaped ring and the sleeve shell, so that electric melting is not influenced by water in the pipeline and outside, and the problem of water-carrying electric melting is solved.
Description
Technical Field
The utility model belongs to the technical field of plastic pipeline connection, and particularly relates to an electric smelting sleeve for rush repair.
Background
At present, after a PE water supply pipeline is damaged, the most common rush-repair mode is hot melt connection or electric melting of a new pipe section, the requirement of the traditional electric melting pipe fitting welding on working conditions is high, the pipe fitting cannot be contacted with water, and otherwise electric melting failure can be caused. In the actual rush-repair process, even if the pipeline valve is closed, more water still exists in the pipeline, the pipeline can be completely emptied in a long time, and if water seepage occurs in the pipeline during electric melting, the effect of electric melting connection can be affected.
For example, chinese patent CN217519408U discloses an electromagnetic heating sealing structure and an electric melting pipe fitting, no effective sealing structure is provided between the pipe and the electric melting pipe fitting body and between the pipe and the metal ring, and the electric melting device needs to perform electric melting under the completely anhydrous condition, so as to effectively ensure the electric melting quality.
Disclosure of Invention
Aiming at the problems existing in the prior art, the utility model aims to provide an electric smelting sleeve for rush repair,
the specific technical scheme is as follows:
the utility model provides a rush-repair is with electric smelting sleeve, sets up between the tubular product that needs to be connected, including electric smelting sleeve body and sleeve housing, the inside of electric smelting sleeve body is equipped with step structure, and step structure's both sides are equipped with the sealing washer, and the sealing washer is located the tip of tubular product that needs to be connected, and electric smelting sleeve body's both ends internal surface is equipped with O type circle groove, is equipped with O type circle in the O type circle groove, and sleeve housing cover is established on electric smelting sleeve body.
Further, the inside diameter of the sleeve shell is smaller than the outside diameter of the electric melting sleeve body, before electric melting, the sleeve shell is installed on the outer surface of the electric melting sleeve body in an extrusion mode, so that the electric melting sleeve body has stress on the inside, and when electric melting is conducted, the bonding strength between the electric melting sleeve body and the outer surface of the pipe is better due to the fact that the stress is applied to the outside.
Further, the outer diameter of the sealing ring is larger than the inner diameter of the pipe to be connected, so that the sealing effect is achieved.
Further, the middle of the step structure is a raised ring, and the sealing rings are arranged on two sides of the raised ring.
Further, the step structure is provided with copper wire holes for connecting copper wires at two ends, the copper wires at two ends are connected, wiring is only needed once, and the forming process is simpler.
The utility model has the beneficial effects that:
according to the utility model, the sealing of the inside of the pipeline is realized through the sealing ring, and the sealing of the outer surface of the pipeline is realized through the O-shaped ring and the sleeve shell, so that electric melting is not influenced by water in the pipeline and outside, and the problem of water-carrying electric melting is solved.
