Abstract

A pipe port includes a connector member having a recessed region with a shape recessed inward, an adapter member inserted into the recessed region of the connector member, and a first sealing member and a second sealing member provided between the connector member and the adapter member, in which the first sealing member and the second sealing member are made of different materials, such as an O-ring and a metal seal, to enhance sealing performance. This configuration ensures a reliable seal in applications requiring vacuum or negative pressure states within a pipe, improving the overall integrity and functionality of the pipe system. The pipe port is particularly suited for maintaining distinct pressure conditions within defined spaces, making it ideal for use in various industrial and technical applications where differential pressure control is critical. A pipe including the pipe port features a secure connection and effective sealing to maintain desired pressure states.

First claim

What is claimed is:

1 . A pipe port comprising:
a connector member; an adapter member; and a first sealing member and a second sealing member provided between the connector member and the adapter member; wherein the first sealing member and the second sealing member are made of different materials; wherein a first through-hole, which is provided to face the adapter member, is formed in the connector member, and the second sealing member is provided between the first through-hole and the adapter member, wherein a second through-hole is formed in the connector member and extends in a direction intersecting a direction in which the first through-bole extends, and the second sealing member is provided to face the second through-hole.

2 . The pipe port of claim 1 , wherein the first sealing member is an O-ring member, and the second sealing member is a metal seal member.

3 . The pipe port of claim 1 , wherein the connector member has a recessed region with a shape recessed inward, and the adapter member is inserted into the recessed region of the connector member.

4 . The pipe port of claim 1 , wherein the first sealing member is provided to be spaced apart from the second sealing member in a direction in which the adapter member and the first through-hole face each other.

5 . The pipe port of claim 3 , wherein the recessed region comprises:
a first recessed region configured to define a space in which the second sealing member is provided; and a second recessed region provided to face the second sealing member with the first recessed region interposed therebetween, the second recessed region being formed to define a stepped portion together with the first recessed region, and wherein the first sealing member is provided between an inner surface of the second recessed region and an outer surface of the adapter member.

6 . The pipe port of claim 5 , wherein a width of the second recessed region is larger than a width of the first recessed region in a region in which the first recessed region and the second recessed region meet together.

7 . The pipe port of claim 5 , wherein an outer diameter of the first sealing member is larger than an outer diameter of the second sealing member.

8 . The pipe port of claim 5 , wherein a center of the first sealing member and a center of the second sealing member are each positioned on a rotation center axis of the recessed region.

9 . The pipe port of claim 5 , wherein a concave section is formed on the outer surface of the adapter member, and the first sealing member is inserted into the concave section.

10 . The pipe port of claim 1 , wherein the first sealing member is spaced apart from the second through-hole in the direction in which the first through-hole extends.

11 . The pipe port of claim 1 , wherein the second sealing member is provided to be spaced apart from a rotation center axis of the second through-hole toward the first through-hole.

12 . The pipe port of claim 1 , further comprising:
a cover member provided to surround an outer side of the adapter member and coupled to the connector member.

13 . The pipe port of claim 1 , further comprising:
a connection member coupled to face the second through-hole, wherein the connection member has a flow path provided to face the second through-hole, and wherein the connection member is coupled to the connector member.

14 . The pipe port of claim 1 , further comprising:
a connection member coupled to face the second through-hole; and an O-ring member provided between the connection member and the connector member.

15 . A pipe port comprising:
a connector member; an adapter member; a first sealing member and a second sealing member provided between the connector member and the adapter member, and a cover member provided to surround an outer side of the adapter member and coupled to the connector member, wherein the first sealing member and the second sealing member are made of different materials, wherein the connector member and the cover member are permanently coupled to each other.

16 . The pipe port of claim 15 , wherein the connector member and the cover member are welded to each other.

17 . A pipe comprising:
an inner pipe part having a first space formed therein; an outer pipe part provided to surround an outer side of the inner pipe part and configured to define a second space together with the inner pipe part; and a pipe port coupled to one side of the outer pipe part and having a space that communicates with the second space, wherein the pipe port comprises:
a connector member having a recessed region with a shape recessed inward;
an adapter member inserted into the recessed region of the connector member; and
a first sealing member and a second sealing member provided between the connector member and the adapter member; and
wherein the first sealing member and the second sealing member are made of different materials,
wherein a first through hole, which is provided to face the adapter member, is formed in the connector member, and the second sealing member is provided between the first through-hole and the adapter member, wherein a second through-hole is formed in the connector member and extends in a direction intersecting a direction in which the first through-hole extends, and the second sealing member is provided to face the second through-hole.

18 . The pipe of claim 17 further comprising a cover member provided to surround an outer side of the adapter member and coupled to the connector member,
wherein the connector member and the cover member are permanently coupled to each other.
