Abstract
The utility model discloses a pipeline connecting structure, which relates to a connecting structure between pipelines, particularly a rapid connecting structure between rigid pipelines. The utility model aims at the inconvenient connection between the rigid pipeline in the prior art to provide a new technical proposal that a screw cap with a central hole is arranged on a main body, an inner pipe passes through the central hole to be inserted in the main body so that a small cavity is formed among the main body, the inner pipe and the screw cap, and a pressing shrinking ring and a sealing gasket are arranged in the cavity. The screw nut is screwed so that the utility model realizes the rapid connection and sealing between the rapid pipelines.
Description
Affiliated technical field
A kind of pipe connecting structure relates to the linkage structure between a kind of pipeline, specially refers to the fast joint structure between a kind of rigid conduit.
Background technique
In the background technique, connection between the rigid conduit, connection as caliduct, adopt connects or the loose joint connection silk more, this just need be the joint of rigid conduit processing internal thread or outer, and processing internal thread or outer silk need special tool, thereby have brought great inconvenience for the installation, maintenance and the transformation of rigid conduit.
Summary of the invention
The purpose of this utility model is to provide fast joint structure between a kind of rigid conduit for society.
The technical solution of the utility model is: the utility model mainly is made of main body and interior pipe, the main body outer surface is provided with outer silk, main body is provided with the nut of band internal thread outward, nut is provided with center hole, interior pipe passes center hole and is inserted in the main body, thereby between main body, interior pipe and nut, form a little cavity, be provided with in the cavity and press shrink-ring and sealing gasket.
The beneficial effects of the utility model are: the utility model directly is inserted in interior pipe in the main body, pushes by tightening nuts and presses shrink-ring and sealing gasket, thereby realized the connection and the sealing of rigid pipe, and loose joint and the outer silk of processing need not be installed, simple to operate, labor intensity is little, the efficiency height.
Description of drawings
Fig. 1, the utility model structure cross-sectional schematic.
Embodiment
As shown in Figure 1, the utility model mainly is made of main body 1 and interior pipe 2, main body 1 outer surface is provided with outer silk, the main body 1 outer nut 3 that is provided with the band internal thread, nut is provided with center hole, interior pipe 2 passes center hole and is inserted in the main body 1, thereby forms a little cavity between main body 1, interior pipe 2 and nut 3, is provided with in the cavity to press shrink-ring 4 and sealing gasket 5.
During installation, earlier interior pipe 2 is passed nut 3 and be inserted in the main body 1, load onto sealing gasket 5 then and press shrink-ring 4, the other end with interior pipe installs again, and last tightening nuts 3 gets final product.
This fast joint structure can be widely used in the rigid line connection of hot-water heating equipment such as boiler, furnace, heat exchanger, water meter.
