Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a tube-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for molding a water supply and a reinforcement pipe using dry air used for reinforcing water supply and drainage.

If cracks or breakage occur in the pipeline (water supply and drainage), it is necessary to reinforce the pipeline. In order to reinforce the pipeline, a reinforcing tube is inserted into an aged pipe, and the pipe is expanded by air to be adhered to the pipe, followed by drying with heated steam.

That is, the high-temperature and high-pressure gas is injected into the reinforcing tube while the reinforcing tube is inserted into the conduit, and the outer surface of the reinforcing tube is brought into close contact with the inner surface of the conduit. Next, high-temperature water vapor injected into the reinforcing tube was put in to cure the epoxy applied to the reinforcing tube and dried.

To this end, the conventional reinforcement tube forming apparatus includes a boiler for heating and water-vaporizing not only an air-introducing pipe but also an air-introducing pipe.

According to the conventional method, in the process of drying by heated steam, water vapor is condensed due to a temperature difference with the tube, thereby causing water droplets to aggregate and flow down.

These droplets interfere with the partially uniform heat exchange at the heat curing site, making it difficult to form a uniform reinforcing tube within a single time.

Due to this condensation phenomenon, there is a great problem that the reinforcing tube is not partially formed at the time of forming the reinforcing tube so that the reinforcing pipe can not be properly reinforced.

Further, in the case of the conventional system, in addition to the injection pipe for the compressed air, an additional pipe for injecting the steam heated by the steam heating boiler was required.

In order to solve the drawbacks of the conventional steam drying method mentioned in the prior art, the present invention is to provide a water and sewage reinforcing tube molding apparatus using dry air in which a reinforcing tube is dry-formed only by dried air without using steam.

According to an embodiment of the present invention, there is provided an apparatus for molding a water supply and a water supply pipe using dry air, comprising: a reinforcing tube for reinforcing water and sewage; A compressor connected to one end of the reinforcing tube for compressing and injecting air into the reinforcing tube; An air heating unit for heating the air compressed by the compressor; A manifold connected to the other end of the reinforcing tube; And a control unit for controlling on / off of the compressor and the air heating unit. The air compressed by the compressor is heated by the air heating unit and injected into the reinforcing tube, so that the reinforcing tube closely contacts the upper and lower water pipes Allow to dry.

The manifold includes a pressure sensor, and the operation of the compressor is controlled by the control unit based on the pressure value measured by the pressure sensor.

The manifold includes a temperature sensor, and the operation of the air heating unit is controlled by the control unit based on the temperature value measured by the temperature sensor.

The manifold includes an on-off valve for communicating the inside of the manifold with the outside, and the on-off valve discharges the air inside the manifold to the outside.

Wherein the opening / closing valve is opened when the control unit receives an opening instruction based on the measured temperature value of the temperature sensor, and the air in the reinforcing tube is discharged to the outside by the opening / closing valve, And the new heated air is controlled to be injected into the reinforcing tube by the air heating unit.

According to the present invention, it is possible to solve the problem caused by the conventional condensation because the upper and lower water tube is dry-formed only by dried air without using water vapor. In addition, since the boiler is not used unlike the existing one, the existing water and sewage reinforcement tube forming apparatus has only to use only one pipe which requires more than two pipelines, and the structure is also improved.

Various embodiments are now described with reference to the drawings, wherein like reference numerals are used throughout the drawings to refer to like elements. For purposes of explanation, various descriptions are set forth herein to provide an understanding of the present invention. It is evident, however, that such embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the embodiments.

The following description provides a simplified description of one or more embodiments in order to provide a basic understanding of embodiments of the invention. This section is not a comprehensive overview of all possible embodiments and is not intended to identify key elements or to cover the scope of all embodiments of all elements. Its sole purpose is to present the concept of one or more embodiments in a simplified form as a prelude to the more detailed description that is presented later.

The present invention provides a water and wastewater reinforcing tube forming apparatus and method for forming a reinforcing tube by dry-forming only air that does not use water vapor.

According to the present invention, it is possible to solve the problem caused by the conventional condensation because the upper and lower water tube is dry-formed only by dried air without using water vapor. In addition, since the boiler is not used unlike the existing one, the existing water and sewage reinforcement tube forming apparatus has only to use only one pipe which requires more than two pipelines, and the structure is also improved.

1 is a block diagram of an apparatus for molding a water supply and a reinforcement pipe using dry air according to an embodiment of the present invention.

As shown in FIG. 1, the apparatus for shaping a water supply and sewage pipe using dry air according to an embodiment of the present invention includes a controller; Compressors; An air heater; Sensors; And an on-off valve.

1 is a block diagram of a compressor; An air heater; Sensors; And that the on / off valve is controlled ON / OFF. Details of the configurations will be described below.

2 is a schematic cross-sectional view of a water and wastewater reinforcing tube forming apparatus according to an embodiment of the present invention.

As shown in FIG. 2, the apparatus for molding a water and sewage reinforcing tube according to an embodiment of the present invention includes a compressor 10; An air heating unit 20; A reinforcing tube (T); A manifold folder 50; Sensors 40; And an opening / closing valve (30).

The compressor 10 is for compressing and injecting air. The air compressed by the compressor is injected into the reinforcing tube T so that the reinforcing tube is expanded and brought into close contact with the pipeline.

The air heating section 20 is operated only when it is necessary to heat the compressed air by the control section. That is, it operates when the compressed air heated into the reinforcing tube (T) is injected and the expanded reinforcing tube is closely contacted and dried on the pipe wall to be molded.

The air heating unit 20 may be installed integrally with the air injection pipe connected from the compressor 10 to the reinforcing tube T or may be installed in a structure in which the air heating unit 20 can be inserted. Since the air heating unit 20 can be used together with the air injection duct connected to the compressor through the reinforcing tube, the air heating unit 20 does not require a separate piping for injecting water vapor by using the boiler as in the prior art . Therefore, it has an advantage that the structure becomes very simple.

The air heating unit 20 can be any means for heating air, and in FIG. 2, a coil is used as such an air heating unit.

The reinforcing tube T is shown in cross-section in Fig. A thermosetting resin 14 is applied to the inner surface of the tube member 12 of the reinforcing tube so that the outer surface of the reinforcing tube is brought into close contact with the inner surface of the conduit by the high pressure gas injected into the reinforcing tube, The reinforcing tube can be hardened.

The manifold folder 50 is connected to the opposite end of the portion where the air injection pipe is connected to the reinforcing tube. This manifold folder 50 is connected to the opposite end after injecting the reinforcing tube into the water supply and sewer pipe which needs reinforcement.

The manifold communicates with the piping of the compressor and the air heating section and finishes the end of the reinforcing tube and contains the following components therein.

The manifold (50) includes sensors (40) and an on / off valve (30).

The sensors 40 may include pressure sensors, temperature sensors, flow sensors, and the like.

The pressure sensor measures the air pressure through the manifold, the temperature sensor measures the temperature of the air passing through the manifold, and the flow sensor measures the air flow through the manifold.

5 is an enlarged view of the manifold 50. As shown in FIG. 5, the manifold folder may include an open / close valve 30, a pressure sensor, and a temperature sensor.

The opening / closing valve 30 serves to discharge the air inside the manifold to the outside. Generally, since the reinforcing tube T is used for a long pipe of 50 m to 100 m, the temperature of the air may be different from the input end and the input end of the input air. That is, heated hot air at the time of input, but at the end of the reinforcing tube, the temperature can be lowered. The cooled air is discharged to the outside through the opening / closing valve 30, and at the same time, the new heated air is injected into the reinforcing tube again.

FIG. 4 is a flowchart of a method for forming a water and sewage reinforcing tube using a water / sewage reinforcing tube forming apparatus according to an embodiment of the present invention.

The method for forming a water supply and sewage reinforcing tube using the apparatus for forming a water supply and sewage pipe according to an embodiment of the present invention is roughly divided into two steps. The two steps are divided into a step (S 410 to S 430) in which the reinforcing tube is brought into close contact with a pipe wall in the pipe, and a step (S 440 to S 495) in which the reinforcing pipe is closely adhered to the pipe wall by injecting the heated air.

After inserting the reinforcing tube into the aged pipe requiring reinforcement first, connect the compressor and the air heating part to one end, and connect the manifold to the other end, and then the forming of the reinforcing tube starts.

In step S 410, compressed air is supplied into the reinforcing tube by using a compressor connected to one end of the reinforcing tube. In this case, the air heating section is not operated yet, and the compressed air is supplied by the compressor.

In step S 420, the pressure is measured using a pressure sensor mounted on the manifold connected to the other end of the reinforcing tube.

In step S 430, it is checked whether the pressure measured in step S 420 is within a predetermined pressure range. It is checked whether the measured pressure P is between P1 and P2 (P1 < P < P2). In this case, P1 represents the minimum pressure at which the reinforcement tube is brought into close contact with the tube wall, and P2 represents the maximum pressure at which the reinforcement tube can be safely retained without breaking. That is, in the step of bringing the reinforcing tube into close contact with the pipe wall inside the pipe, if the measured pressure maintains the pressure between P1 and P2, the reinforcing pipe will be brought into immediate contact with the pipe wall. If the pressure is outside this range, the pressure is adjusted to the pressure of the compressed air from the compressor by turning to step S 410 to maintain the pressure between P1 and P2.

In step S404, the opening of the manifold folder is opened as a start of molding the reinforcing tube attached to the pipe wall by injecting the heated air after the reinforcing tube is attached to the pipe wall. Opening valve of the manifold is opened to release the air inside the reinforcement tube to the outside and to introduce new air (heated air) into the reinforcement tube.

In step S 450, the flow rate of the heated air injected into the reinforcing tube is maintained. Q = Q ', where Q is the flow rate of the incoming air and Q' is the flow rate of the outgoing air. That is, it is controlled so that the flow rate of the air flowing into the inside of the reinforcing tube becomes equal to the flow rate of air flowing outside the reinforcing tube.

In operation S 460, the air heating unit is operated. Step S 460 is described as a step separate from steps S 440 and S 450, but steps S 440 through S 460 are not sequentially generated but actually occur simultaneously. That is, the open / close valve of the manifold is opened and the air heating unit is operated to inject the heated air into the reinforcing tube, and at the same time, the flow rate of air is maintained at Q = Q '.

Thereafter, in step S 470, the temperature T of the outflow air is measured by the temperature sensor of the manifold folder, and it is confirmed whether the measured temperature T is within the temperature range of T 1 and T 2. Where T1 is the molding starting temperature at which the reinforcing tube is molded and T2 is the maximum temperature at which the reinforcing tube can be securely molded. Therefore, the measured temperature must be in the range of T1 and T2 so that the reinforcing tube can be safely molded.

If the measured temperature is between T1 and T2, the on / off valve is closed in step S480, and the compressor and the air heating unit are turned off in step S490. That is, the compressor and the air heating unit are temporarily turned off since hot air injected into the reinforcing tube is sufficient to form the reinforcing tube.

On the other hand, if the measured temperature is not between T1 and T2, the process returns to step S440.

Finally, in step S 495, the temperature of the injected hot air is constantly checked during the molding of the reinforcing tube, and it is continuously checked whether the temperature of the air is maintained between T 1 and T 2. If the temperature of the air is outside the range, the process returns to step S404.

In this way, during the process of forming the reinforcing tube, the hot air is continuously maintained inside and the cooled air is discharged to the outside, thereby completing the forming of the reinforcing tube.

The description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features presented herein.
