Description
Disclosure of the Invention The present disclosure relates to a fusion splicer of an electric fusion polyethylene joint pipe and more particularly to a fusion splicer of an electric fusion polyethylene having a pressure tightness test module capable of confirming the fusion quality of an electric fusion portion of a fusion- To a welder of a joint pipe.
Herein, the background art relating to the present invention is provided, and they are not necessarily referred to as known arts.
When a large amount of cooling water or city gas is supplied to a necessary place in a nuclear power plant or a city gas reservoir, a metal pipe is mainly used as a piping material.
However, for example, in a nuclear power plant, a large amount of cooling water is required to cool a primary coolant in a nuclear power plant. Accordingly, a large-diameter cooling water inlet pipe is buried in the sea, and seawater is taken out through it to be used as cooling water. When a metal pipe is used as a lead-in pipe, there is a problem that the lead pipe is easily corroded by seawater. Therefore, recently, a synthetic pipe such as a polyethylene pipe is used instead of a metal pipe as a coolant intake pipe.
In particular, polyethylene has excellent chemical resistance, hygienic properties, flexibility, light weight, and the like compared with other materials. Particularly since polyethylene has no electric corrosion (corrosion corrosion) and corrosion and can be used semi-permanently, It is used not only for the inlet pipe but also for the upper and the sewage pipes and for gas transfer.
When such a polyethylene pipe is used for piping, it is necessary to connect the polyethylene pipes to each other. In the method of connecting the polyethylene pipes, there are a mechanical connection method using a metal coupling and a method of connecting using a heat. Since the coupling and the connecting material used for it are made of metal, there is still a possibility of corrosion. In the case of connecting the polyethylene pipe, a method of connecting using mainly heat is used.
Heat fusion method and electro fusion method are also used for the connection of polyethylene pipe by using heat. Butfusion method, socket fusion method, And saddle fusion.
Here, electric fusion is divided into electric socket fusion and electric saddle fusion, which is performed by inserting a heating coil into an electronic PE coupling pipe, and applying a power source to the heat pipe of the electronic PE coupling pipe, It is a fusion bonding method in which a desired portion is melted and connected.
On the other hand, after the electric fusion is completed, it is general to test the performance of the fused portion. In this regard, Korean Patent Laid-Open No. 10-2009-0067303 discloses a piping material connection portion sensing device, which includes a cover for collecting a leaked gas, a sensor for detecting a leaked gas, And an RFID for informing the user of the information.

As described above, since the conventional device for testing the performance of the fused portion is provided separately from the fusing device, there is an inconvenience that the fusing performance testing device must be installed independently after the fusing is completed by the fusing device.
It is an object of the present disclosure to provide a fusion splicer for an electric fusion polyethylene joint pipe having a pressure tightness test module capable of performing electrical fusion of a polyethylene pipe and airtightness testing of a fusion splice by a single device.
