SU1520201A1 - Automatic outlet for protecting pipelines from freezing - Google Patents

Abstract

The invention relates to pipe fittings and relates to the constructive implementation of an automatic release to protect the pipeline from freezing. The goal is to increase reliability and simplify the design. The automatic release comprises a housing 2 mounted in a ring 3, a diaphragm 7 placed in the housing, a dividing housing on cavities 8 and 9. The cavity 8, located directly above the diaphragm, is made in the form of an ice-formation chamber filled with water. On the diaphragm 7, a shut-off valve 11 is fixed, which opens against the pressure of water in the pipeline and separates the cavity 9 under the diaphragm from the cavity of the pipeline 1. The cavity 9 communicates with the atmosphere through channels 12. Since the ice-forming chamber is almost completely buried in the pipeline, it appears the ice pipeline is also formed in the ice formation chamber. When water freezes in the chamber, the ice begins to press on the diaphragm that moves the valve. As a result, water from the cavity of the pipeline 1 enters the cavity 9 and the channels 13 and flows out. As a result of the circulation of water in the pipeline 1, ice is melted on its walls and in the cavity 8, as a result of which the pressure on the diaphragm stops and the valve 11 returns to its original position. 3 il.

A diaphragm 7 in the housing, dividing the housing on cavities 8 and 9, Cavity 8, located directly above the diaphragm, is made in the form of an ice-formation chamber filled with water. On the diaphragm 7, a shut-off valve 11 is fixed, which opens against the pressure of water in the pipeline and separates the cavity 9 under the diaphragm from the cavity of pipeline 1. The cavity 9 is in communication with the atmosphere through channels 12, since the ice-forming chamber is almost completely buried in the pipeline when it appears on the walls

the ice pipeline is also formed in the ice formation chamber. When water freezes in the chamber, the ice starts

put pressure on the diaphragm that moves the valve. As a result of this, water from the cavity of the pipeline 1 enters the cavity 9 and the channels 13 and flows out. As a result of water circulation

In the pipeline 1, ice is thawed on its walls and in the cavity 8, as a result of which the pressure on the diaphragm stops and the valve 11 returns to its original position. 3 il.

The invention relates to pipe fittings and concerns the constructive implementation of automatic discharge to protect the pipeline from freezing.

The goal is to increase the reliability and simplify the design.

FIG. 1 shows an automatic release, longitudinal, section j in FIG. 2 - section A-A in FIG. 1j in FIG. 3 - location of the automatic release on the pipeline.

Automatic release to protect | Pipeline 1 from freezing includes a housing 2 located in a ring 3 having an annular protrusion 4 on its inner surface through a sealing gasket 5 and fixed to the ring 3 by means of studs 6, and the ring 3 is connected to the wall of the pipeline 1 by welding. An automatic vtusk is placed on the pipeline offset from angle o1. horizontal axis of the pipeline down. The housing 2 contains a diaphragm 7 that separates the housing on cavities 8 and 9. The cavity 8, located directly above the diaphragm, is formed as an ice-formation chamber filled with water through the plug 10. On the diaphragm 7, a locking valve 11 is attached that opens against the water pressure in the pipeline and separating the cavity 9 under the diaphragm from the cavity of the pipeline 1. The cavity 9 is in communication with the atmosphere through channels 12, which have thermal insulation 13 and are covered at the outlet with flaps 14.

The ice-forming chamber is almost completely buried in the pipeline,

This process of ice formation in it is close to the process of ice formation in the pipeline. With the appearance of ice on the walls of the pipeline, it is also formed in the ice formation chamber. When water freezes in the chamber, ice pushes against the diaphragm 7, which moves the valve 11, as a result of which water from the cavity of the pipeline 1 enters the cavity 9 and into the channels 13 and flows out. As a result of the circulation of water in the pipe 1, ice melts on its walls and in the cavity 8, as a result of which the pressure on the diaphragm stops, the valve t1 returns to its original position
