Abstract

The utility model discloses a conduit connecting device consisting of trough conduits, sealing rings and couplers. The ends of left and right conduit 1 being connected with each other are provided with trough conduits 2 with outer groove, both ends of the two trough conduits 3 is provided with the sealing ring 4 at the outer surface, the outer margin of the sealing ring is locked with upper and under couplers 3 and 5, the left and right ear hole of the upper and under couplers 3 and 5 is provided with the fastening bolt 6 which can fix the two trough conduits together and clamp the sealing rings. The flanges on both sides of the coupler is blocked at the groove on the trough conduits, which can prevent the conduit moving, the sealing ring can enhance the sealability of conduit port. As a result the conduit connecting device is of convenient loading or unloading, good sealability, stable connection, convenient operating and is suitable for oil transportation conduit and water supply conduit.

Description

A kind of pipeline connecting device

One, affiliated technical field

The utility model relates to a kind of pipeline connecting device, be particularly useful for the connection of rigid conduit.

Two, background technique

Before the utility model proposes, the connection between the tube and tube in the rigid conduit, employing be flange to be housed in the end of pipe, place seal ring in the middle of two flanges, two flanges butt joint back is connected firmly together with a plurality of bolts.Its deficiency of the connecting mode of this kind pipeline is to connect the dismounting trouble, and sealing is poor.

Three, summary of the invention

In order to solve the deficiencies in the prior art, the utility model provides a kind of connection convenient disassembly, the pipeline connecting device of good seal performance.

The technological scheme that its technical problem that solves the utility model adopts is: this pipeline connecting device mainly is made up of trough pipe, seal ring, joiner; The end of the left and right pipeline that connects is fixedly connected with the trough pipe of band outer annular groove, be with the seal ring of the pipeline leak of liquid that can prevent to flow through on the external cylindrical surface of two trough tube end opposite positions, be buckled with the inner groove section upper and lower joiner identical on the sealing circle outer rim, and two side flanges of joiner are positioned at trough pipe outer annular groove with the seal ring section configuration; String has the clamping bolt that two trough pipes are fixedly connected and clamp seal ring in the hole on the left and right ear of upper and lower joiner.

The beneficial effects of the utility model are two trough pipes to be connected firmly together by bolt because this device adopts upper and lower joiner to be stuck on the trough pipe, so connect convenient disassembly; Simultaneously, the end that the outer seal ring of trough pipe is sealed two trough pipes in the joiner inner groove makes the liquid of the pipeline of flowing through under high pressure non-leakage, good seal performance.This pipe coupler is simple in structure, and it is convenient to use, long service life, and cost is low, is applicable in the oil transportation, feedwater piping of various occasions to use.

Four, description of drawings

Fig. 2 is a transverse views of the present utility model

1. pipelines among the figure, 2. the trough pipe is 3. gone up joiner, 4. seal ring, 5. lower link device, 6. bolt.

Five, embodiment

In the accompanying drawings, the utility model pipeline connecting device is mainly by the trough pipe, seal ring, and joiner is formed.Trough pipe 2 is welded on the end of the left and right pipeline 1 that needs connection, and the relevant position is provided with circular groove on the external cylindrical surface of trough pipe 2.Be with seal ring 4 on the external cylindrical surface of two trough pipes, 2 end opposite positions, this circle mainly seals, and purpose is to prevent to flow through the leak of liquid of pipeline.Be buckled with upper and lower joiner 3,5 on the outer rim of seal ring 4, the inner groove section of joiner is identical with the shape of seal ring 4 sections, and two side flanges of joiner are positioned at the outer groove of trough pipe 2.Be inserted with clamping bolt 6 in the hole on the left and right sides ear of upper and lower joiner 3,5, clamping bolt 6 can make upper and lower joiner flange and inner groove thereof clamp two trough pipes 2 and seal ring 4, thereby realizes the quick connection of pipeline.

Claims
