Description

Technical Field

[0001] This utility model relates to a dry connector that can be disassembled and is leak-free under certain pressure, belonging to the field of dry connector technology. Background Technology

[0002] A dry-type disconnector is used to connect and install pipelines on both sides, enabling the pipeline to be transported or separated.

[0003] For example, a dry-type disconnector disclosed in application number CN202321626216.X belongs to the technical field of dry-type disconnector technology. It addresses the problem that the dry-type disconnector is usually directly separated from the surface of the pipeline, which makes the inner wall of the connector easily wear against the surface of the pipeline. Long-term separation installation causes wear at the pipeline connection, which greatly reduces the normal use effect of the dry-type disconnector. The connector body includes a gasket that is snapped into place at both ends of the inner wall of the connector body. This solution achieves a stable connection between the gasket and the adhesive plate and the connector body through the mutual installation and cooperation of the horizontal plate and the ring plate, preventing the gasket from loosening from the inner wall of the connector body and causing the device to separate from the external pipeline and wear. Through the mutual installation and cooperation of the limiting plate and the limiting post, the limiting plate limits the installation of the connecting plate on the outer wall of the connecting plate, so that the inner wall of the connecting plate is stably installed and connected to the horizontal plate, avoiding wear caused by long-term friction on the pipeline surface.

[0004] The drawback of the aforementioned dry-type connector is that it is prone to leakage during use. To address this, we have designed a dry-type connector that can be disassembled and installed without leakage under certain pressure. Utility Model Content

[0007] The aforementioned dry connector, which is detachable and leak-free under certain pressure, also includes a support base, the top of which is provided with a buffer frame capable of supporting the sealing sleeve.

[0008] In the aforementioned dry connector that is detachable and leak-free under certain pressure, a rubber pad is installed inside the buffer frame, and a buffer contact is installed on the top of the rubber pad, which is connected to the sealing sleeve.

[0009] In the aforementioned dry-type connector that is detachable and leak-free under certain pressure, the outer ring of the second connecting flange is provided with multiple bolt connecting plates, and the outer ring of the first connecting flange is provided with multiple bolt connecting posts, and the multiple bolt connecting posts are bolted to the multiple bolt connecting plates.

[0010] In the aforementioned dry-type connector that is detachable and leak-free under certain pressure, an external connecting sleeve is installed in the middle of one end of the first connecting flange, and a sealing end cap is installed at one end of the external connecting sleeve.

[0011] In the aforementioned dry connector that is detachable and leak-free under certain pressure, a sealing insert is installed in the middle of the sealing end cap.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model discloses a dry connector that can be disassembled and leak-free under certain pressure.
