Centering unit for piping connection that prevents scale generation {CENTERING UNIT FOR PIPING CONNECTION PREVENTING SCALE}

The present invention relates to a centering unit for connecting pipes, and specifically, to prevent scale from occurring in step areas, both ends of the inner side of the body of the center ring are formed low, and the central part is formed high, so that the height with the pipe is high. This relates to a centering unit for piping connection that minimizes the difference and prevents scale generation to relatively reduce the step height.

In general, pipes connecting pipes are used to transport various fluids. It is desirable to construct the entire pipeline as a single pipe because problems such as fluid leakage do not occur, but due to space constraints and production limitations, pipes are made by connecting pipes.

The centering unit connects the pipes that make up this conduit. The centering unit ensures that the two pipes are aligned and connected without being misaligned, and the O-ring seals the gap between the two pipes to prevent fluid flowing through the pipe from leaking.

Domestic registered patent No. 10-1155427 “Triple sealing centering”, Domestic public utility model No. 20-2017-0001745 “Double sealing centering structure of vacuum piping clamp”, Domestic registered patent No. 10-1807757 “Vacuum piping for sealing” Device", Domestic Patent No. 10-2015611 "Centering unit for piping connection", Domestic Patent Publication No. 10-2022-0030082 "Centering unit for piping connection and manufacturing method thereof", etc.

The centering unit includes a center ring with a hollow interior, an O-ring that is fitted to the outer periphery of the center ring to seal the gap between the two pipes, and a clamp that pressurizes and seals the flanges of the two pipes to the O-ring.

However, this conventional centering unit is formed of a ring-shaped body and a protrusion that is formed vertically at the outer center of the body and is joined to an O-ring. When the body is inserted between pipes, there is a step due to the difference in thickness from the pipe. This occurs, and there is a problem in that scale is generated in the stepped area when fluid flows.

To solve this problem, Domestic Public Utility Model No. 20-2019-0001577, “Centering Unit Used in Piping Connections,” is disclosed.

As shown in FIG. 1, the centering unit used in the pipe connection is a centering unit (20) connected to a pair of pipes (10, 11) consisting of pipe bodies (10a, 11b) and flanges (10a, 11b), respectively. In, the centering unit includes a center body 21 and an O-ring 22, and the center body 21 has a T-shape located in the space provided by a pair of flanges 10a and 11b, and the center body ( The side and bottom surfaces of 21) are in close contact with the flanges (10a, 11b), the protruding part of the center body is in contact with the O-ring (23), and the upper surface of the center body (21) coincides with the inner surface of the pipes (10, 11). It is characterized by not forming a step.

However, the centering unit used in such conventional pipe connections must process the inside of the flange to the same height as the center body, but when the pipe diameter is large, precise processing is difficult, which increases manufacturing costs.

Domestic Open Utility Model No. 20-2019-0001577 Domestic Registered Patent No. 10-1155427 Domestic Open Utility Model No. 20-2017-0001745 Domestic Registered Patent No. 10-1807757 Domestic Registered Patent No. 10-2015611 Domestic Public Patent No. 10-2022-0030082
