SU1221457A1 - Pipeline quick-release joint - Google Patents

Description

The invention relates to mechanical engineering, namely to quick-disconnecting joints of pipelines, and can be used in pneumatic-hydraulic systems for the rugged connection and disconnection of pipelines,

The purpose of the invention is to simplify the design and reduce the diametrical dimensions due to the location of the spring outside the semi-connector behind the end of the casing and making a helical groove on the surface of the protrusion on the semi-connector.

The drawing schematically shows the proposed quick-release connection of pipelines.

The connection consists of two semi-connectors 1 and 2 joined together. Semi-connector 2 consists of a case 3 having a protrusion 4, around which the casing 5 is expanded, pressed against the protrusion 4 by the spring 6. The housing 5 in the working position holds the projections 7 of the multilobe collet 8 in the outer annular a groove 9 formed on the guide surface of the housing of the half-connector 1. The collet 8 contains additional loading lobes 10, which fall into an annular groove 11 adjacent directly to the protrusion 4, in which the screw through the groove 12 is cut fil, pitch and diametral times Editor Yu.

the measures of which are commensurate with the corresponding sizes of the spring 6 in the free state. Removable rings 13 ensure tightness

5 connections in the docked position. When assembling the device, the spring 6 is screwed through the screw groove 12 onto the casing 2, compressed by the device even after rolling

10 of the casing 5 is released, pressing the casing to the protrusion 4. The multi-lobe collet 8 is made integral, which simplifies the design and assembly of the connection. The connection works as follows.

f5 way.

To connect the semi-connector 2, the housing 5 is retracted to the right, overcoming the force of the spring 6, and pulling the semi-connector 2 along the guide surface 20 of the housing of the semi-connector 1. When the protrusions 7 of the collet 8 are clamped into the annular groove 9, the housing 5 is released. Spring-loaded casing 5 is in the docked position
