Description

A connector using pipe line system

The present invention relates to a pipe connector, in particular, it is easy to combine the pipes used for water supply, etc., and is suitable for preventing the leakage of fluid flowing through the pipe as well as stable flow of fluid even under high water pressure conditions. It relates to a pipe end that can be maintained as well as easy to prevent and install.

In general, water supply is to bury pipes in the ground to supply tap water.

The pipes used for such water supply are used to connect several pipes to each other for the installation of water supply facilities, and most often use cast iron pipes, steel pipes, etc. In recent years, cement lining pipes, galvanized steel pipes, epoxy coated steel pipes, etc. It is partially used by painting and coating, and some impact-resistant PVC water pipes and PE water pipes are used.

Dual cast iron pipes, steel pipes, etc. due to the leakage of water due to corrosion, the water capacity decreases in proportion to time, it is a direct factor in the pollution of tap water, such as red and white water.

In addition, cement lining pipes, galvanized steel pipes, epoxy coated steel pipes, etc., are easily peeled off by coating and coating due to shrinkage, expansion difference, and impact due to temperature variation, and thus, water pipe life does not last long. Therefore, although the impact resistant PVC pipe or PE water pipe is used as an alternative, there is a problem in the joint portion of the pipe or there is a difficulty in construction.

That is, the joint portion of the pipe is higher than the other parts, the water pressure is generated, due to the nature of the joint to be bonded to the pipe and other problems, such as leakage occurs intensively.

Therefore, in order to solve problems such as leaks occurring at the joints of the pipes, the joints of the pipes and the pipes are welded or connected through pipe connectors.

1 and 2 are views for explaining a conventional impact resistant PVC pipe connector.

1 is a partial cross-sectional view of a connector that is installed in the bent portion of the tube to install the tube in a curved manner, the tube connector shown in Figure 1 is an elbow (tube) connector.

As shown, the conventional elbow connector has an elbow housing 1 made of cast iron into which straight pipes 9 are inserted at both ends, respectively, between the inserted straight pipe outer circumferential edge 9a and the housing inner circumferential edge 1b. A sealing ring 3 is interposed inside the housing to prevent fluid from leaking into the gap 8.

Then, a pair of fixing pieces 4 are fixed to a predetermined position on the outer circumferential edge 1a of both ends of the housing, and a fixing rod 7 positioned between the pair of fixing pieces 4 is fixed to the straight outer circumferential edge 9a. Clamp 5 is installed.

Then, the first and second hemisphere pieces 5a and 5b are screwed and installed on the outer periphery 9a of the straight pipe, and the support rods 7 formed on the hemisphere pieces are positioned between the pair of fixing pieces 4 to support the rods. The head 7a is caught by the fixing piece 4 so that the straight pipe 9 is not separated by hydraulic pressure or vibration.

Figure 2 is a partial cross-sectional view for explaining another conventional elbow type tube connector, as shown in Figure 2, the conventional tube connector is an elbow type formed therein the insertion grooves 11 are inserted into each of the straight pipe at both ends There is a housing 10, a sealing ring 12 is interposed between the inserted straight outer periphery (9a) and the housing inner periphery (10a) to prevent leakage.

In order to prevent the sealing ring 12 and the inserted straight pipe 9 from being separated from the housing 10 by hydraulic pressure and vibration, a triangular rubber ring 13 and a stopper 14 are sequentially disposed inside the housing 10. Is inserted into the cap, the cap 15 is coupled to the outside of the housing by screwing.

Therefore, the sealing ring 12, the triangular rubber ring 13, the stopper 14, and the cap 15 are sequentially coupled in a state where the straight pipe 9 is inserted into the insertion groove 11 of the housing 10. Connect

In particular, the elbow tube connector shown in Figure 2 is a triangular rubber ring, stopper, cap to prevent the separation of the sealing ring and straight pipe, but the cap is loosened by the vibration and water pressure applied to the housing, as well as leaks, Polluted water from outside is introduced into the housing to contaminate the fluid.

Second, problems such as corrosion occur.

That is, the pipe connector of FIG. 1 has a housing made of cast iron, which is likely to be corroded by the fluid, thereby degrading the contamination and durability of the fluid.

Third, there is inconvenience of installation.

That is, the pipe connector shown in Figure 1 is made of cast iron material is heavy, in order to prevent the separation of the straight pipe, the clamp should be installed on the outer periphery of the straight pipe, the fixing piece should be integrally formed on the outside of the housing, and the support rod should be formed on the clamp. Therefore, the structure is complicated, and the installation is inconvenient.

And, the pipe connector shown in Figure 2 requires a number of parts, such as a triangular rubber ring, stopper, cap, and has been inconvenient to install must be installed sequentially.

The present invention is to solve the problems of the prior art, the object of the present invention is to provide a pipe connector in which water tightness is improved, corrosion resistance is excellent, and installation is easy.

Therefore, the pipe connector according to the present invention, in order to achieve the above object, in the pipe connector for connecting the pipes flowing fluid, sealing the gap between the housing and the tube inserted into the housing and the inside of the housing It is characterized in that it comprises a sealing means for preventing the leakage of the fluid and the separation preventing means is formed on the outside of the housing to prevent the tube from being separated from the housing by the hydraulic pressure and impact of the fluid.

The housing is made of PVC resin or polyethylene resin, and the sealing means is formed with a sealing ring which forms an insertion groove in the inner circumference of the housing and is interposed in the insertion groove to seal the gap.

The separation preventing means comprises first and second hemispheres screwed to the outer periphery of the housing and the outer periphery of the tube.

In addition, the housing is formed with annular projections on the outer periphery adjacent to both ends, and the first and second hemispheres are formed with a concave surface in contact with the annular projection.
