Problems solved by technology

Sleeve compensator seal leakage is an important cause of compensator corrosion and damage
Leakage, rupture, excessive friction and other defects of the pipeline compensator will bring large or small abnormal operation to the pipeline network system and even cause major accidents
Through the analysis of the failed sleeve compensator, the pipeline deviates from the design position due to various reasons, causing the inner and outer sleeves of the sleeve compensator to be subjected to lateral torque, so that the sealing packing in the gap is radially asymmetrically squeezed, and the seal is damaged
In addition, the packing cavity of the sleeve type compensator sealing material is composed of the outer sleeve of the sleeve type compensator, the inner sleeve and the pressing rings or bosses on both sides of the packing cavity, but the pressing rings or bosses on both sides of the packing cavity are in contact with the inner sleeve. Or the fit gap of the sleeve parts is large, resulting in a large gap in the sealing packing cavity, and the seal is damaged under high temperature and high pressure

Embodiment 1

[0016] figure 1 It is a schematic diagram of the overall structure of the high temperature and high pressure sleeve type compensator in the embodiment of the present invention;

[0017] A high-temperature and high-pressure sleeve type compensator is composed of an outer sleeve 1, an outer pressure tube 2, an inner sleeve 3, a compression bolt 4, a sliding bearing compression ring 5 with self-lubricating properties, and a sealing packing 6. The inner diameter of the outer sleeve 1 is stepped, and there are 3 steps in total, which increase successively from left to right. The outer surface of the middle section of the inner sleeve 3 is provided with a ring-shaped outer convex ring as an anti-detachment shackle, and two self-lubricating features. The sliding bearing pressure ring 5 is set on the outer surface of the inner sleeve 3 on the left side of the ring-shaped outer convex ring, and inserted into the right end of the outer sleeve 1, and the sliding bearing pressure ring 5 w...

Abstract

The invention aims to provide a high-temperature and high-pressure sleeve type compensator. Sliding bearings with a self-lubricating characteristic are used as compression rings on two sides of sealing packing of the compensator, an outer sleeve, an inner sleeve and the sliding bearings with the self-lubricating characteristic are assembled to form a sealing material packing cavity of the high-temperature and high-pressure sleeve type compensator, and the sliding bearings which are used as the compression rings are arranged on two sides of the sealing material packing cavity. By the aid of the sliding bearings with the self-lubricating characteristic, namely the compression rings, concentricity of the outer sleeve and the inner sleeve can be maintained, resistance of the inner sleeve and the outer sleeve of the compensator to tangential torque which destroys sealing capacity of the sealing packing can be strengthened, the sliding bearings are also the compression rings on the two sides of the sealing material packing cavity, accordingly, the sealing material packing cavity is provided with a sliding bearing compression ring supporting structure, gaps among the sliding bearings, namely the compression rings, and the inner sleeve and the outer sleeve of the compensator are small, contact area of working liquid media of the compensator and the sealing packing is reduced, requirements on performances of the sealing packing of the compensator under high-temperature and high-pressure conditions are lowered, the structure of the compensator is simplified, and a sealing performance of the sealing packing is improved.

Description

technical field [0001] The invention relates to a high-temperature and high-pressure sleeve type compensator, which belongs to the technical field of pipeline components. Background technique [0002] High temperature and high pressure sleeve compensator is an important part of high temperature and high pressure pipe network. Sleeve compensator seal leakage is an important cause of compensator corrosion and damage. Leakage, rupture, excessive friction and other defects of the pipeline compensator will bring large or small abnormal operation to the pipeline network system and even cause major accidents. Through the analysis of the failed sleeve compensator, the pipeline deviates from the design position due to various reasons, causing the inner and outer sleeves of the sleeve compensator to be subjected to lateral torque, so that the sealing packing in the gap is radially asymmetrically squeezed, and the seal is damaged . In addition, the packing cavity of the sleeve type ...
