Abstract
The utility model relates to a combination water-proof type electric melting sleeve for electric melting pipelines. The combination water-proof type electric melting sleeve is characterized by further comprising a plastic sleeve and seal rings which are used for connecting the pipelines. The inner diameter of the electric melting sleeve is of a reducing structure, the inner diameter of one end of the electric melting sleeve is matched with the outer diameter of a pipeline, a seal ring extrusion convex ring integrally connected with the electric melting sleeve is arranged in one end of the electric melting sleeve matched with the plastic sleeve, and grooves for placing seal rings are respectively arranged on inner ports at two ends of the plastic sleeve. The combination water-proof type electric melting sleeve for the electric melting pipelines has the advantages that in rush repair, a replacing pipeline is sealed with the end portion of an original pipeline, water in the pipeline is prevented from flowing out, and an electric melting area is in a water-free state; and the electric melting sleeve not only facilitates on-site repair operation, is convenient, simple and fast to install, and greatly shortens time for pipeline repair operation, but also can ensure pipeline repair welding quality, and prolongs service life of a water supply pipeline.
Description
Technical field
The utility model belongs to water supply line recovery technique field, particularly relates to a kind of hot melt pipeline combination waterproof type electric smelting sleeve.
Background technique
The PE material since characteristics such as its intensity height, anticorrosive, nontoxic, heat-resisting quantity, low temperature resistance to sudden heating and environment protection type be widely used in plumbing and make the field.Because it can not get rusty, so, be the desirable tubing that substitutes common iron supply pipe, the pipeline of being made by the PE material has been widely used in the municipal water supply industry at present.When the PE water supply line takes place to leak or damages, must rush to repair fast and effectively, its repair generally is that the employing hot melten type connects, and namely needs ducted water is all discharged totally in the repairing process, treats can rush to repair operation after the pipe surface drying.Under the not tight situation of valve closing, can't in time repair operation especially, so not only can influence the pipeline rehabilitation welding quality, cause inconvenience for the field repair operator, but also can prolong the pipeline rehabilitation time, and then make troubles to urbanite water consumption.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, be convenient to the field repair operation and can shorten the hot melt pipeline combination waterproof type electric smelting sleeve of repair time significantly.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Hot melt pipeline combination waterproof type electric smelting sleeve, comprise the electric smelting sleeve, also comprise the plastic sleeve and the seal ring that are connected with pipeline for pipeline, described electric smelting sleeve diameter is variable-diameter structure, electric smelting sleeve one end internal diameter matches with the plastic sleeve external diameter, the variable-diameter structure that the other end internal diameter matches with outer diameter tube, the end inside that described electric smelting sleeve matches with the plastic sleeve external diameter is shaped on the seal ring extruding bulge loop that is connected as a single entity with it, and described plastic sleeve two ends internal orifice all is shaped on for the groove of placing seal ring.
The utility model can also adopt following technological scheme:
The groove of described plastic sleeve two ends internal orifice is trapezoidal groove.
Described plastic sleeve adopts the PE raw material to make.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, namely in water supply line repairing operation, by being sleeved on plastic bushing and the extruding of the seal ring on seal ring and the electric smelting sleeve bulge loop of changing pipeline and former pipe end, to change pipeline and former pipe end and implement tight seal, preventing that the water in the pipeline from flowing out, and then guarantee that the electric smelting zone is in anhydrous state.The employing said structure not only is convenient to the field repair operation, simple installation shortens the pipeline rehabilitation activity duration fast, significantly, but also can guarantee the pipeline rehabilitation welding quality, has prolonged the working life of water supply line.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model plastic sleeve;
Fig. 3 is that the utility model uses view.
Among the figure: 1, plastic sleeve; 1-1, groove; 2, seal ring; 3, electric smelting sleeve; 3-1, seal ring extruding bulge loop; 3-2, resistance wire electrode; 4, change pipeline; 5, former pipeline.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, hot melt pipeline combination waterproof type electric smelting sleeve comprises electric smelting sleeve 3, also comprises the plastic sleeve 1 and the seal ring 2 that are connected with pipeline for pipeline.Described electric smelting sleeve diameter is variable-diameter structure, and namely one end internal diameter matches with the plastic sleeve external diameter, the variable-diameter structure that the other end internal diameter matches with outer diameter tube.The end inside that described electric smelting sleeve matches with the plastic sleeve external diameter is shaped on seal ring extruding bulge loop 3-1, processing for convenience, described seal ring extruding bulge loop 3-1 and electric smelting sleeve are set to integrated structure, and described plastic sleeve two ends internal orifice all is shaped on for the groove 1-1 that places seal ring.
In the present embodiment, the groove 1-1 of described plastic sleeve two ends internal orifice is trapezoidal groove.
In the present embodiment, described plastic sleeve adopts PE tubing to make, and described plastic sleeve also can adopt PP tubing to make, and described seal ring 2 adopts rubber seal.
Working principle of the present utility model is:
See also Fig. 3, operator at first cut the leakage of water supply line part or broken parts and amputate, to change pipeline 4 is placed between two sections former pipelines 5, then electric smelting sleeve and seal ring are placed on an end of changing pipeline 4 and former pipeline 5 respectively, again plastic sleeve 1 is sleeved on the connecting part of changing pipeline 4 and former pipeline 5, advance the electric smelting sleeve of changing pipeline 4 and former pipeline 5 one ends in opposite directions, make the seal ring extruding bulge loop 3-1 in the electric smelting sleeve seal ring is squeezed in the trapezoidal groove of plastic sleeve, can seal to prevent that the water in the pipeline from flowing out with changing pipeline 4 and former pipeline 5 connecting parts, guarantee that the electric smelting zone is in anhydrous state.At this moment, operator start the power supply of electro-fusion sleeve, change pipeline 4 respectively, plastic bushing connects with the electric smelting of electro-fusion sleeve with electro-fusion sleeve and former pipeline 5, plastic bushing.
