(2) bushing type swivel joint, can two or more media through-flow, and the hypermedia structure that circulates is simple superposition just, and operation is heavy, exceeds the normal running moment of operator, although emerge for many years, but does not commercially substantially use.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of gas-liquid universal type swivel joint.This gas-liquid universal type swivel joint can make liquid handling arm when not needing independent dress flexible pipe or loading arm, and circulate two kinds of liquid mediums simultaneously, and compact structure, simple to operate, is convenient to promote.
The technical problems to be solved in the utility model is achieved through the following technical solutions, and a kind of gas-liquid universal type swivel joint, is characterized in: comprise liquid phase swivel joint, is provided with gas phase swivel joint coaxially in described liquid phase swivel joint; Described gas phase swivel joint comprises the left pipe of mutual grafting and right pipe, the other end of left pipe and right pipe is used for connecting with muffler, described liquid phase swivel joint comprises inner ring and the outer ring of coaxial setting, the passage being used for liquid phase and passing through is formed between inner ring and gas phase swivel joint, the raceway of band ball is provided with between inner ring and outer ring, the end face of outer ring is connected with one end of flange by fixing device, the other end of flange is used for being connected with the arm pipe of Liquid transfer arm, and the side of the relative flange of described inner ring is used for being connected with the arm pipe of Liquid transfer arm.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs,
The surface of contact of described left pipe and right pipe grafting is inclined-plane, and surface of contact is provided with radial seal structure.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, is provided with axial seal structure between described inner ring and flange.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and end face and the flange of described outer ring are bolted.
In addition, the invention also discloses a kind of liquid entrucking arm with gas-liquid universal type swivel joint, comprise column, inner arm, inner arm is locked, uprights vertical is fixed on ground, inner arm one end is locked on column by inner arm, arm during the inner arm the other end is connected by gas-liquid universal type swivel joint successively, outer arm and nanubrium, the outlet of nanubrium connects sealed cap, between the side of middle arm and outer arm top, balace weight is installed, the fixed plate of balace weight is arranged on the side of relative equilibrium device on middle arm, inner arm, the muffler linked into an integrated entity by gas-liquid universal type swivel joint is provided with in middle arm and outer arm, muffler and inner arm, liquid channel is formed between the arm pipe of middle arm and outer arm, the suction port of muffler stretches out outer arm and is connected with sealed cap, the air outlet of muffler is stretched out inner arm and is connected with oil-gas recovery device.
Compared with prior art, the utility model has following technique effect:
1) gas phase is creatively placed in the middle of liquid-phase tube by the utility model, dexterous in structure, while weight, the flow area of medium does not diminish, for 4 cun of liquid phase loading arm, adopt 5 writing brush chuck 2 writing brushes, the flow area that the flow area of interlayer is greater than 4 cun;
2) formed between inner ring and inner connecting tube and be used for the passage that passes through of liquid phase, liquid channel adopts end face seal, and left joint and right connector connecting part are with guiding surface and adopt radial seal structure, and installation, maintenance is convenient;
3) reduce dimensioned required precision, if two sealing surfaces all adopt end face seal, then dimension precision requirement is very strict, otherwise one of them easily leaks; After changing this structure, dimensioned required precision can reduce, and the up-to-standard rate of product rises;
4) use is safer, because gas phase channel is arranged on liquid channel internal layer, even if gas phase channel leaks, the gas spilt also is leak into liquid channel, flow in materials handling equipment by liquid channel, can not evaporate in air, avoid causing potential safety hazard.
