Description

Device for connect of pipes

The present invention relates to a connection device for the piping material to be constructed after connecting and fixing two or more piping materials.

In general, piping materials include plated pipes, non-ferrous metal pipes, and concrete pipes that compensate for the shortcomings of corrosion in ferrous metals, and recently, plastic pipes developed by the petrochemical industry have been developed, as well as drinking water piping for homes and factories. It is used as industrial piping materials such as sewage and sewage, which are excellent wastewater and excellent piping, and strong toxic fluid, and is very useful in all industrial fields and daily life.

However, ferrous metal-plated pipes and non-ferrous metal pipes are more economical in view of the high production cost and corrosion, and are effective in terms of management after the completion of pipes. In particular, plastic piping materials, polyethylene (PE), polyvinyl chloride (PVC), polypropylene (poly propylene / PP) and the like are used a lot.

On the other hand, the method of connecting the plastic piping material, the method of welding using electricity (electric welding type), the method of using a heat shrink sheet (socket welding type), the method of connecting using a flange tube (flange welding type), and A method of connecting using a PVC DC socket is used.

In the method of fusion using the electricity, as illustrated in FIG. 1, after the pipe members 10 and 10 ′ of the connection target are horizontally aligned, the foreign substances at the joints are removed. In this way, the junction part is wound with a rectangular heating sheet 12 having a heat transfer medium 11 embedded therein, and the center of the heating sheet 12 is fixed with a fixture such as a buckle band 13, and then both ends Fix it. When the heat generating sheet 12 is fixed as described above, the connection terminal of the fusion machine 14 is connected with the terminal of the heat transfer medium 11, and then a diameter is set in the fusion machine 14 and power is applied to the heat transfer medium 11. Generates heat At this time, when heat is generated in the heat transfer medium 11, the end of the connection target pipe member 10, 10 'is melted and fused, and when the welding is completed, the power is cut off, further tighten the buckle band 13 and constant cooling It is sufficient to take time and construct the piping material which completed cooling.

However, the method of fusion using electricity as described above has a problem that the heat generating sheet deforms the circular shape of the drain pipe by heating a large area of the drain pipe, and the deformed portion is crushed inside, thereby reducing the flow rate. In the part where the drain pipe and the drain pipe are in contact with each other, only the heating sheet supports the drain pipe, so that the heat sink is weak in uneven settlement.

In addition, in the method of fusion using the heat shrink sheet, as shown in FIG. 2, after the piping materials 10 and 10 ′ of the connection object are aligned horizontally, foreign substances at the joining part are removed. The heat shrink sheet 21 is wound around the joint where the foreign matter is removed, and the end of the heat shrink sheet 21 is heated and attached using a torch lamp. The heat shrink sheet 21 thus attached is heated evenly from the center of the heat shrink sheet 21 to the edge using a torch lamp, and the heating is heated to the extent that the hot belt melted at both ends of the heat shrink sheet 21 is pushed out. The heat shrink sheet 21 may be wrapped with a stainless band 22 or a PE band, and then fixed with a bolt 23 and a nut 24, cooled with a constant cooling time, and then, the cooling material may be constructed.

However, the method of fusion using the heat shrink sheet as described above has difficulty in evenly distributing the heat to the heat shrink sheet with the torch lamp, and if the heat is uneven, the workability is poor and the workability is poor. Corrosion occurs in the ground when buried by, and the shrinkage rate of the drain pipe and stainless steel is different, there is a problem that can not be maintained because of the coupling force leak.

In addition, the method of connecting using the flange pipe, as shown in Figure 3, the polyethylene double-walled piping 10 (10, 10 ') is produced first, and separately by injecting or processing the flange 31 pipe material 10 It is a method that is fused and fixed to both ends of the (10 '), and connected when laying the piping material (10, 10'). In this method, the rubber ring 32 is mounted at a portion where the pipe member and the pipe member come into contact with each other, and the two semicircular flanges 31 are fastened to the periphery of the pipe member 10, 10 ', and then bolts 33 are formed on both sides. , There is a method of tightening with a nut (34), inserting a gasket like a general water flange, fastening with a plurality of bolts, nuts around the circle, and processing the flange and attaching it to the end face of the drain pipe, and then the net structure on the flange end The aspiration of was inserted and the both drainage pipes were connected.

However, as described above, the method of connecting using a flange pipe is very expensive because the flange is processed separately and attached, and the construction prevents leakage if the site to prevent leakage does not align the drain pipe in a straight line with a ring or plate. It is difficult, and since the flange of the drain pipe is installed in the manufacturing plant and put into the site, it is impossible to cut and use the drain pipe at the site, so that it is impossible to cope with the waste of manpower and time due to long working hours.

In addition, the method of connecting using the PVC DC socket, as shown in Figure 4, after the horizontally aligned drain pipes (40, 40 ') having a constant waveform horizontally aligned, then the grooves of the waveform 41 The rubber ring 42 is attached to the part and the inner part of the socket 43 is connected by interference fit.

However, the method of connecting by using the PVC DC socket as described above is very vulnerable to uneven settlement because the rubber ring is compressed to support the drainage pipe, and the durability is weak because the rubber ring is corroded to the waste water such as acid and alkaline. When the rubber ring is corroded, there is a problem of contaminating soil and water due to leakage of wastewater.

The present invention has been made in view of the above-mentioned conventional defects, and its object is to simplify the assembly process and to prevent a lot of manpower and time from being consumed, thereby improving the economical effect due to excellent workability and corrosion after construction. The present invention relates to a pipe connecting device that can prevent occurrence, prevent leakage of water and prevent contamination of soil and water, improve reliability of products, and use semi-permanently stably.

In order to achieve the above object, the present invention provides a connection device for a pipe member formed by spirally joining a semi-finished product in the form of a pipe having a space formed therein, wherein a heat transfer medium may be provided in spaces corresponding to both end surfaces of the pipe member to be connected. After interposing the rod, it is characterized in that by applying power to the heat transfer medium to heat-bond both ends of the resin rod and the pipe material to be connected.
