Description

Multipurpose connector of water separator

Technical Field

The utility model belongs to the technical field of water heating accessories, and particularly relates to a multipurpose connecting piece of a water separator.

Background

The water separator is widely applied in water heating engineering, is generally used as a junction for collecting and separating water flow and is connected with a plurality of waterways, so that a large number of reducing connections are involved. For example, chinese patent CN217441074U discloses a floor heating water separator with equal split structure, which comprises a water inlet main pipe and a water return main pipe, which are fixedly installed on a bracket, wherein the water inlet main pipe and the water return main pipe are respectively provided with the same number of branch pipes and are connected with a buried pipeline. The pipelines connected with the water separator can be made of various materials, such as aluminum plastic pipes, galvanized pipes, PPR pipes and the like, and the pipelines made of different materials need different connection modes; for this purpose, there is a need in the art to provide a water separator in the form of a plurality of connectors to cope with the demands of different applications.

Disclosure of Invention

The utility model aims to provide a multipurpose connecting piece of a water separator, which is applicable to most connecting occasions.

Therefore, the technical scheme adopted by the utility model is as follows: multipurpose connecting piece of water knockout drum, its characterized in that: the external sleeve comprises an external sleeve body and an internal insert, wherein the external sleeve body is in an open circular tube shape and is divided into an upper part and a lower part, the inner diameter of the upper part is smaller than that of the lower part, a step surface is arranged between the inner walls of the upper part and the lower part, the inner wall of the upper part is a smooth inner wall, and the inner wall of the lower part is provided with internal threads; the inner insert is in an open circular tube shape, the outer diameter of the inner insert is smaller than the inner diameter of the upper part of the outer sleeve, and the inner insert is in clearance fit with the upper part of the outer sleeve; the lower part of the outer wall of the inner insert is provided with a protruding ring, and the outer diameter of the ring is smaller than the inner diameter of the lower part of the outer sleeve and larger than the inner diameter of the upper part of the outer sleeve; the ring and the outer wall of the inner insert form a step surface which is in interference fit with the step surface between the inner walls of the upper part and the lower part of the outer sleeve.

The outer wall of the embedded part is provided with a sealing ring, and the sealing ring is arranged below the ring.

The insert has a smooth inner wall. Or (b)

The inner wall of the inner insert is provided with internal threads.

The application mode of the utility model is as follows: the inner insert is sleeved in the outer sleeve, and at the moment, the inner insert cannot leave the outer sleeve due to the blocking between the two step surfaces, but can freely rotate due to the clearance fit with the upper part of the outer sleeve; the lower part of the external sleeve is connected with a water separator port to be connected, the water separator port is provided with external threads, the lower part of the external sleeve is provided with internal threads, the external threads and the internal threads can be connected in a meshed manner, and as the threaded connection is tighter and tighter, the sealing ring generates elastic deformation and tension, so that the external sleeve is tightly connected with the water separator port, and the internal insert and the external sleeve cannot move in any direction; then connecting the pipeline to be connected with the embedded part, if the pipeline to be connected is in hot melt connection, selecting the embedded part with smooth inner wall, and welding the pipeline with the embedded part; if the connection is threaded, the inner insert with the internal thread is selected to be connected with the pipeline, and in this case, the inner insert can be connected with the pipeline first and then fastened by the external sleeve.

Therefore, the utility model can complete the connection of various modes by only matching one coat piece with two different embedded pieces, reduces the types of accessories, and is convenient to use, safe and reliable.

Detailed Description

See the drawings. In this embodiment there is an external sleeve 1 and an internal insert 2, the connection to be connected being a tee 3, the connection of which has an external thread 31. The external sleeve is sleeved outside the inner insert, the external sleeve 1 consists of an upper part 11 and a lower part 12, the inner diameter of the upper part is smaller than that of the lower part, a step surface 13 is arranged between the inner walls of the upper part and the lower part, and the inner wall of the lower part is provided with an internal thread 14; the lower part of the outer wall of the inner insert 2 is provided with a convex ring 22, and a step surface is formed between the ring 22 and the outer wall of the inner insert 2 and is matched with the step surface 13; the outer wall of the insert 2 is also provided with a sealing ring 23 which is arranged below the ring 22; the inner wall of the insert 2 is provided with internal threads 24 which cooperate with external threads 31 of the tee.

When the embodiment is used, the inner insert 2 is sleeved into the outer sleeve 1, and the sealing ring 23 is arranged; the tee 3 is then connected to the insert 2 by engagement of the threads 31, 24; and then the thread 14 of the external sleeve is connected with the port of the water separator, and in the process of screwing up the thread, the matching of the two step surfaces compacts and tightens the internal insert 2 and the sealing ring 23, so that tight sealing connection is completed.
