Embodiment Construction

[0022] The application will be described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific embodiments are only used to further illustrate the application, and cannot be interpreted as limiting the protection scope of the application. The above application content makes some non-essential improvements and adjustments to this application.

[0023] Such as figure 1 As shown, a U-shaped sealer for tunnel anti-crystallization includes an adapter 1 , a nut 2 , an elbow 3 and a U-shaped sealer body 4 .

[0024] The front end of the adapter 1 is connected to the outlet of the tunnel drainage pipe. The outer diameter of the rear end of the adapter 1 is equal to the inner diameter of the nut 2, and the rear end of the adapter 1 is provided with external threads, and the nut 2 is provided with internal threads. The rear end is screwed into the nut 2 to form a threaded connection; the outer diameter of the fro...

Abstract

The invention discloses a U-shaped sealing device for tunnel anti-crystallization. The device comprises a connector, a screw nut, a elbow and a U-shaped sealing device body, wherein the front end of the connector is connected at the water outlet of a tunnel drainage pipeline; the outer diameter of the back end of the connector is equal to the inner diameter of the screw nut; external threads are arranged at the back end of the connector; internal threads are arranged on the screw nut; the rear end of the connector is screwed into the screw nut to form a threaded connection; the outer diameterof the front end of the elbow is slightly less than that of the screw nut; and a convex strip projecting outside is arranged at the front end of the elbow; a clamping strip projecting inside is arranged at the rear end of the screw nut; the convex strip and the clamping strip consist of two symmetrical 1 / 4 circular structure, the front end of the elbow extends into the screw nut and rotates 90 degree to form clamping buckle connection; the U-shaped sealing device body and the elbow are formed in one, and the water inlet and outlet of the U-shaped sealing device body are flush. The U-shaped sealing device has the advantages that the U-shaped sealing device for anti-crystallization of the tunnel is mounted on the tunnel drainage pipeline, which can effectively cut off the contact between thedrainage pipeline and the outside air and solve the problem of crystallization of the tunnel drainage pipeline.

Description

technical field [0001] The invention relates to the technical field of pipe fittings, in particular to a U-shaped sealer for tunnel anti-crystallization. Background technique [0002] It is very troublesome to clean and maintain the drainage pipes in the tunnel in the later stage of installation. The water quality in the tunnel is alkaline and contains a large amount of calcium and magnesium ions, which are easily mixed with CO in the air. 2 The reaction produces crystals that block the drainage pipes, and after the drainage pipes in the tunnel are installed, it is difficult to clean them up, resulting in the accumulation of these crystals over time, which greatly affects the drainage and water flow capacity of the drainage pipes, and increases the water pressure inside the tunnel. Structural security. Contents of the invention [0003] The object of the present invention is to provide a U-shaped sealer for tunnel anti-crystallization, which can effectively block the cont...
