Hereinafter, a preferred embodiment of a pipe connector having a function of improving assembly and airtightness and a pipe connection method using the same according to the present invention will be described in more detail with reference to the accompanying drawings.

Hereinafter, elements having the same function in all the following drawings will be denoted by the same reference numerals, and repetitive description will be omitted. Further, the following terms are defined in consideration of functions in the present invention, Should be interpreted as.

As shown in Figure 1 to Figure 12, the present invention, the bolt-shaped connector 210 to form a first pipe (P1) to one side, and the second pipe for connection to communicate with the first pipe (P1) Located between the nut-shaped connector 220 for receiving and supporting (P2) when fastening the bolt-shaped connector 210 and the nut-shaped connector 220, the fast and smooth connection and solid support of the second pipe (P2) And a sealing ring 130 formed of a binding member 110 and a pipe support holder 120, a first sealing ring 131, and a second sealing ring 132.

First, the bolt-shaped connector 210 is made of a metal material such as copper or stainless steel, and on one side thereof, for example, a first pipe P1 connected to an air conditioner outdoor unit (not shown) is integrally formed or formed to be detachable. .

In addition, a male screw 211 for fastening with the female screw 222 of the nut-shaped connector 220 is formed at one side of the outer surface, and therein, for example, a second pipe P2 connected to an air conditioner indoor unit (not shown); A first coupling space 212 is formed to form a slightly smaller diameter in which the first sealing ring 131 is accommodated. The first coupling space 212 has a larger diameter than the diameter of the first coupling space 212 and the binding member 110. A large diameter second engagement space 213 is formed in which the second sealing ring 132 is accommodated.

In addition, a curved portion 214 is formed at a portion where the first coupling space 212 and the second coupling space 213 of the bolt-shaped connector 210 contact each other.

Accordingly, the binding member 110 and the pipe support holder 120 positioned inside the bolt-shaped connector 210 and the nut-shaped connector 220 by the fastening force during the fastening operation of the nut-shaped connector 220. The second sealing ring 132 is expanded and deformed by a strong compression by the forward operation, and is pushed toward the first coupling space 212 through the curved portion 214 to completely block the gap except the moving passage of the fluid. For example, it is possible to reliably prevent the leakage of the fluid, for example, the refrigerant gas, thereby improving airtightness.

The nut-shaped connector 220 is formed with a female screw 222 corresponding to the male screw 211 to be fastened to the male screw 211 of the bolt-shaped connector 210 in the longitudinal direction therein, the female screw 222 One side of the support groove 223 is formed to support the rear end surface of the pipe support holder 120, one side of the support groove 223, for example, a pipe coupling hole for coupling with the second pipe (P2) 221 is formed.

Here, the support groove 223 is preferably formed to correspond in the same form according to the shape of the rear end surface of the pipe support holder 120.

For example, when the rear end surface of the pipe support holder 120 is formed in a disk shape, the support groove 223 is also formed in a disk shape groove, and the rear end surface of the pipe support holder 120 is formed in an inclined circle shape. The groove 223 is also preferably formed as an inclined circle groove.

Accordingly, the support groove 223 closely supports the rear end surface of the pipe support holder 120 to facilitate assembly and at the same time, when fastening with the bolt-type connector 210, the pressing force is safely and strongly forward. I can deliver it.

The binding member 110 is formed to form an approximately long ring using a metal such as stainless steel or a stainless alloy, and an inner surface of the coupling member 111 is coupled to the outer surface of the second pipe P2, for example. Is formed, the tapered inclined coupling portion 112 is formed on one side of the linear coupling portion 111.

Here, the linear coupling portion 111 is preferably formed with a diameter (diameter) the same size as the outer diameter of the second pipe (P2).

Accordingly, when the second pipe P2 is inserted into the linear coupling portion 111, the binding member 110 and the second pipe P2 are in close contact with each other and the second pipe P2 is in close contact with the second pipe P2. Since it is not easily separated out of the binding member 110, the connection work between the first pipe P1 and the second pipe P2 may be performed more smoothly.

That is, the linear coupling part 111 accommodates and supports the second pipe P2, for example, and serves to prevent unnecessary deformation such as loosening or crushing of the second pipe P2 during assembly operation. By preventing the movement of the pipe to facilitate the use of tools such as spanners can be made a smooth connection.

In addition, the inclined coupling portion 112 is inclined so that the diameter gradually decreases in the longitudinal direction from the outer side to accommodate and couple the tapered outer surface of the pipe support holder 120, that is, the inclined surface 122. Is formed.

Accordingly, the binding member 110 and the pipe support holder 120 form a strong coupling with each other by a fastening force during the fastening operation of the nut-shaped connector 220.

The pipe support holder 120 is a component for firmly holding and supporting the second pipe P2 inserted into the nut-shaped connector 220, and easily penetrates into the outer surface of the second pipe P2. It is preferable to be made of a metal having a hardness equal to or higher than the hardness of the pipe to be joined so as to exhibit a strong support force, and a ring-shaped spike 121 is formed at one end thereof, and the spike 121 At one side of the tapered tapered inclined surface 122 is formed, the outer surface is coupled to the inclined coupling portion 112 of the binding member 110.

Here, the inclined surface 122 is preferably formed to form an inclination angle corresponding to the inclined coupling portion 112 of the binding member 110.

Accordingly, the pipe support holder 120 is deeply inserted into the inclined coupling portion 112 of the binding member 110 by a fastening force when the bolt-shaped connector 210 and the nut-shaped connector 220 are fastened.

At this time, the spike 121 formed at the tip of the pipe support holder 120 is compressed and deformed to move in the direction of the circle center of the second pipe P2 so that the spike 121 is moved to the outer surface of the second pipe P2. Digging into it, you get a solid support.

That is, when the binding member 110 and the pipe support holder 120 are coupled, the pipe support holder 120 is moved forward into the inclined coupling portion 112 of the binding member 110 and thus the one of the inclined surfaces 122. Spikes 121 formed on the side are also compressed and deformed through the inclined coupling part 112 to be retracted in the direction of the center of the circle so that the outer surface of the second pipe P2 can be easily dug and firmly supported.

In addition, the spike 121 is preferably formed with an inclined blade (121a) to dig more easily to the outer surface of the second pipe (P2) coupled to the distal end circumferential surface to achieve a firm fixation.

Accordingly, when the bolt-type connector 210 and the nut-type connector 220 are fastened, the spikes 121 are compressed and deformed in the direction of the circle center of the second pipe P2 by the fastening force. ) Is more easily dug into the outer surface of the second pipe (P2) to achieve a more solid support force to prevent the second pipe (P2) is pushed or escaped even when high pressure occurs.

Here, the inclined blade (121a) is formed so as to form a too steep inclination angle may not cut or puncture the outer surface of the pipe coupled to the leading edge is sharp, and if formed to form an inclined slope too loosely coupled to the leading edge Since it is difficult to penetrate the outer surface of the pipe to be formed is preferably formed to form a roughly 3 ° to 45 ° degree.

The sealing ring 130 has excellent chemical resistance to prevent corrosion from a fluid such as a refrigerant gas, and does not change its characteristics even when contacted with a fluid such as a cool refrigerant gas, as well as weather resistance. It is preferable that it is formed of Teflon material, which is one of polyfluoroethylene-based synthetic fibers having good frictional coefficient due to its good performance and ability to withstand the action of the natural environment such as weather, rain, moisture, and gas in the air. The first sealing ring 131 is located at one end of the second pipe (P2) coupled to achieve the airtight, and the second sealing ring 132 is located at one end of the binding member (110).

The sealing ring 130 is located inside the bolt-shaped connector 210 and is expanded and deformed by the fastening force of the nut-shaped connector 220 while being leaked in a fluid such as a refrigerant gas. It is possible to reliably prevent the fluid (gas, liquid, solid) from leaking out of the space or vice versa, thereby improving the airtightness.

That is, when the first sealing ring 131 is fastened to the bolt-type connector 210 and the nut-type connector 220, the binding member located inside the bolt-type connector 210 and the nut-type connector 220 ( 110, the pipe support holder 120, the second pipe P2, and the like move forward and are strongly compressed and deformed by the front end of the second pipe P2, thereby expanding the first coupling space of the bolt-shaped connector 210. At 212, the gap except for the movement passage of the fluid is primarily blocked, and the second sealing ring 132 is expanded and deformed with strong compression by the forward operation of the binding member 110 and the pipe support holder 120. As a result, the second coupling space 213 of the bolt-shaped connector 210 blocks the gaps except the moving passages of the fluid, so that leakage of the fluid is reliably prevented, thereby improving airtightness.

Here, the curved portion 214 is formed at the border portion where the first coupling space 212 and the second coupling space 213 of the bolt-shaped connector 210 contact each other.

Accordingly, the binding member 110 and the pipe support holder 120 positioned inside the bolt-shaped connector 210 and the nut-shaped connector 220 by the fastening force during the fastening operation of the nut-shaped connector 220. When the second sealing ring 132 is expanded and deformed by strong compression by the forward motion, the second engagement space 213 is pushed toward the first engagement space 212 through the curved portion 214 to exclude the moving passage of the fluid. It will completely block the gap.

In addition, the inner surface diameter of the sealing ring 130 is formed to the same size or the size that can be fitted to the outer surface of the second pipe (P2) to be coupled, for example, firmly secure the outer surface of the second pipe (P2) To accommodate (holding) to prevent the second pipe (P2) from being separated or loose in the bolt-shaped connector 210 and the nut-shaped connector 220 during the assembly operation to improve the fastening efficiency.

The binding member 110 and the pipe support holder 120 according to the present invention having such a configuration is preferably made of stainless steel (SUS) or stainless alloy.

That is, when the binding member 110 and the pipe support holder 120 are formed of stainless steel or a stainless alloy, the hardness of the binding member 110 and the pipe support holder 120 is generally higher than that of a pipe formed of a metal having a weak hardness, such as copper (Cu) and aluminum (Al). Because of this, the outer surface of the second pipe P2 to which the spikes 121 of the pipe support holder 120 are coupled is more easily dug into the outer surface, thereby increasing the supporting force, thereby achieving more firm fixing.

A method of connecting the first pipe P1 and the second pipe P2 by using the pipe connector according to the present invention configured as described above is as follows.

First, as shown in FIG. 13, for example, the first sealing ring may be formed into the inner first coupling space 212 of the bolt-shaped connector 210 formed to be integrally formed or detachable with the first pipe P1 on one side thereof. 131 is seated, and a second sealing ring 132, a binding member 110, and a pipe support holder 120 are sequentially inserted into the second coupling space 213.

Next, the male screw 211 formed on the outer surface of the bolt-shaped connector 210 and the female screw 222 formed on the inner surface of the nut-shaped connector 220 are fastened so that only a part of the threads are mutually coupled.

Next, by inserting the second pipe (P2) into the coupling hole 221 formed on one side of the nut-shaped connector 220, the front end is advanced to be in contact with the first sealing ring 131. (S30)

At this time, the second pipe (P2) is passed through the inner surface of the pipe support holder 120, the binding member 110 and the second sealing ring 132 while contacting one end of the first sealing ring 131, the soft interference fit. Because of this configuration, the binding member 110 and the second sealing ring 132 are in close contact with the second pipe P2 so that the second pipe P2 can be easily moved out of the binding member 110 and the second sealing ring 132. Since it is not separated, the connection work of the second pipe P2 can be performed more smoothly.

That is, the second pipe (P2) is in close contact with the inner surface of the binding member 110 and the second sealing ring 132 to prevent the second pipe (P2) is loose and detached during the assembly operation and at the same time the movement of the pipe It is possible to achieve a smooth connection by making it easier to use tools such as spanners.

Next, the nut-shaped connector 220 is turned clockwise to fasten the bolt-shaped connector 210 so that almost all of the threads of the bolt-shaped connector 210 are coupled to each other, thereby firmly fixing the second pipe P2.

At this time, by deeply fastening the female screw 221 formed on the inner surface of the nut-shaped connector 220 with the male screw 211 formed on the outer surface of the bolt-shaped connector 210, as shown in Figure 6, the pipe support holder 120 At the same time as the inclined surface 122 of the () is advanced into the inclined coupling portion 112 of the binding member 110, the spike 121 is pressed in the direction of the circle center of the second pipe (P2).

Accordingly, since the spike 121 formed at one end of the pipe support holder 120 is pulled into the compressive deformation, the outer surface of the second pipe P2 is dug and supported to form a firm fastening state.

At the same time, the first sealing ring 131 and the second sealing ring 132 is compressed by the fastening force of the bolt-type connector 210 and the nut-type connector 220 while being expanded and deformed to the outside, the bolt-type connector ( Since the inside of the 210 and the nut-shaped connector 220 is hermetically sealed, the sealing performance may be improved to prevent leakage of the fluid that may occur at the portion where the second pipe P2 is coupled.

Therefore, the connection between the first pipe P1 and the second pipe P2 is made simple and quick by the fastening of the bolt-type connector 210 and the nut-type connector 220, and at the same time, a firm fixing is achieved and leakage is prevented. do.
