Abstract
The utility model relates to a novel ultralow-temperature loading and unloading arm. The novel ultralow-temperature loading and unloading arm comprises an inner arm, an outer arm and a plurality of rotary joints, wherein the upper and lower ends of the rotary joints firmly lock an upper-end flange plate and a lower-end flange plate respectively, an outer ferrule is arranged on the outer side of the upper-end flange plate, and an inner ferrule is arranged on the inner side of the lower-end flange plate; a main sealing ring is arranged at the joining position of the outer ferrule and the inner ferrule on the upper-end flange plate, and a lower sealing ring is arranged at the joining position of the outer ferrule and the inner ferrule on the lower-end flange plate; and a nitrogen distribution cavity which is provided with a gas inlet and a gas outlet is formed inside the inner ferrule, and rotary rolling balls are arranged on the inner ferrule outside the nitrogen distribution cavity. The novel ultralow-temperature loading and unloading arm has the advantages that: various parts of the rotary joints are uniformly shrunk under low-temperature working conditions, the lowest temperature can reach -197 DEG C, and the problem that the deformation of a sealing surface is not uniform at low temperature is effectively solved, so that the problem about low-temperature sealing is solved; and the moisture in the air cannot be frozen in a raceway to damage the raceway, so that the flexible rotation of the rotary joints is ensured.
Description
Technical field
The utility model relates to a kind of fluid assembly and disassembly equipment, relates in particular to a kind of novel ultralow temperature loading and unloading arm.
Background technology
According to the mode of transport of liquid, the liquid oil transfer arm can be used for terrestrial transportation and water transportation two big classes.Terrestrial transportation can be divided into train transportation and vehicular transport, is called the low temperature oil filling riser usually, and water transportation can be divided into ocean freight and rivers transportation, is called loading and unloading arm peculiar to vessel usually.The low temperature oil filling riser is the loading and unloading that are specifically designed to transfer of cryogenic medium tank car, and the each several part of its SAH shrinks under the service conditions of low temperature, and the sealing surface distortion is inhomogeneous, and hermetically-sealed construction can not get guaranteeing, therefore can't realize the low temperature sealing requirement.In addition, in whole handling process, airborne moisture can freeze in raceway and damage raceway, and it is dumb to cause making SAH to rotate.Therefore, need reasonably improve existing structure.
Summary of the invention
To above defective, the utility model provides that a kind of each several part shrinks evenly under the service conditions of low temperature, leak tightness better, SAH rotates novel flexibly ultralow temperature loading and unloading arm, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of novel ultralow temperature loading and unloading arm; Comprise inner arm, outer arm and some SAHs; Inner arm is connected with column, and said inner arm is connected with outer arm through SAH, and said SAH is locked upper flanges dish and lower end flange respectively in two ends up and down; Be positioned at the upper flanges dish outside and be provided with outside race, be positioned at flange inboard, lower end and be provided with inside race; Said outside race and inside race are positioned at upper flanges Pan Xianjieweizhichu the primary seal circle are set, and said outside race and inside race are positioned at flange cohesive position place, lower end lower seal is set; Said inside race inside offer one have an inlet, outlet the nitrogen distribution cavity, be positioned on the inside race of the nitrogen distribution cavity outside swing roller be installed.Said primary seal circle periphery is with time seal ring.
The beneficial effect of the described novel ultralow temperature loading and unloading arm of the utility model is: through the firm SAH of hermetically-sealed construction is set; Is furnished with nitrogen purging mechanism simultaneously; The each several part of SAH is shunk under the service conditions of low temperature evenly; Minimum can the solution low temperature lower sealing surface effectively and be out of shape uneven problem, thereby solve a low temperature sealing difficult problem to-197 ℃; SAH adopts the lubricating method of unlubricated fat, feeds nitrogen and makes all the time drying of raceway in whole handling process, and assurance water in air branch can not freeze in raceway and damage raceway, thereby has guaranteed that SAH rotates flexibly.
