Description

Spiral pipe compensator

Technical Field

The utility model relates to the technical field of pipeline compensators, in particular to a spiral pipe compensator.

Background

In the industrial production process, heat and refrigerant media such as steam, water, heat conducting oil, refrigerating fluid and the like which are higher than or lower than normal temperature are often conveyed through pipelines, and the pipeline conveying design process of the media is required to solve the problem of expansion caused by heat and contraction caused by cold;

the existing common ways for solving the problem of expansion with heat and contraction with cold of the industrial pipeline are natural compensation of an angle, compensation of a corrugated pipe, compensation of a graphite sleeve and the like: 1 traditional bending natural compensation advantages: the device is not influenced by medium temperature and pressure, has no physical gap, is consistent with pipeline performance parameters, has small thrust of a unit expansion group fixing support column and is irrelevant to medium pressure; disadvantages: the occupied space of a plane or a vertical surface is large, the stability of a vertical installation pipe system is poor, the compensation capacity is poor, the compensation distance is short, and the vertical installation pipe system cannot be used for buried pipeline arrangement; the corrugated pipe compensator is divided into transverse distortion compensation and longitudinal expansion compensation, and has the advantages that: the transverse torsion replaces the traditional alpha bending transverse arm by the corrugated pipe, so that the installation space is greatly reduced; longitudinal expansion compensation uses corrugated pipe sections to replace working pipeline space occupation without change (commonly used for buried pipes); bellows compensator disadvantages: the corrugated pipe is characterized in that the thermal expansion and contraction peristaltic movement of the pipe system are concentrated, the pipe is easy to fatigue and damage, and the performance parameters of the pipe are inconsistent with those of the pipe, and the corrugated pipe is not suitable for high-pressure parameter mediums; 3 the graphite sleeve compensator is divided into a plane rotation type and a longitudinal telescopic type, and has the advantages that: the plane rotary graphite sleeve compensator is matched with the compensation capability of the expansion group of the unit greatly through the rotation of the two compensators, so that the long-distance conveying resistance is reduced, the thrust of the fixed support column of the expansion group is small, and the compensation occupied space is moderate; disadvantages: the device has physical gaps, is easy to leak after long-time operation, needs periodic maintenance, is not suitable for high-parameter mediums and is not suitable for buried modes; the longitudinal telescopic graphite sleeve compensator is only used in an underground mode or in a narrow pipe gallery for short distance, and has the unique advantage of small occupied space (rarely used); none are suitable for use on narrow tube rack, and therefore a spiral tube compensator is proposed to address the above-mentioned problems.
