2) band hose type liquid handling arm; inner arm adopts flexible pipe to be connected with outer arm junction, outer arm with nanubrium junction; when operating, workman need overcome the crooked torsion of flexible pipe; flexible pipe belongs to consumable accessory in addition; open-air atmosphere flexible pipe aged deterioration; cause gaseous state chemical medium to leak in air, use dangerous;
3) jacket type liquid handling arm adopts telescoping swivel joint, but just simple stack in structure, liquid phase is in centre, and gas phase is in interlayer, and weight is overweight, and operation is heavy, exceeds the normal running moment of operating personal.
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 liquid entrucking arm with New type rotating joint.This liquid entrucking arm is not in the situation that needing independent dress flexible pipe or handling arm, and the two kinds of liquid dielectrics that simultaneously circulate, and simple and compact for structure, easy to operate, are used safer.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of liquid entrucking arm with New type rotating joint, be characterized in: comprise column, inner arm, inner arm locking, described column is vertically fixed on ground, inner arm one end is locked on column by inner arm, arm during the inner arm other end connects by liquid phase swivel joint successively, outer arm and nanubrium, the outlet of nanubrium connects seal cap, between the side of described middle arm and outer arm top, balancing device is installed, it is characterized in that: in described liquid phase swivel joint, be provided with coaxially gas phase swivel joint, described inner arm, in middle arm and outer arm, be provided with the muffler linking into an integrated entity by gas phase swivel joint, muffler and inner arm, between the arm pipe of middle arm and outer arm, form liquid channel, the admission port of described muffler stretches out outer arm and is connected with seal cap, the air extractor duct of described muffler stretches out inner arm and is connected with oil-gas recovery device, described gas phase swivel joint comprises left pipe and the right pipe of mutual grafting, the other end and the muffler of left pipe and right pipe join, described liquid phase swivel joint comprises inner ring and the outer ring of coaxial setting, between inner ring and gas phase swivel joint, be formed for the passage that liquid phase is passed through, between inner ring and outer ring, be provided with the raceway with ball, the end face of outer ring is connected with flange by anchor fitting.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and the contact surface that described left pipe and right pipe join is inclined-plane, and contact surface is provided with radial seal structure.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, between described described inner ring and flange, is provided with axial seal structure.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs,
End face and the flange of described outer ring are bolted.
Compared with prior art, the utlity model has following technique effect:
1) the utility model is creatively placed on gas phase in the middle of liquid-phase tube, dexterous in structure, when weight lightens, the flow area of medium does not diminish, the 4 cun of liquid phase handling arms of take are example, adopt 5 writing brush chuck 2 writing brushes, the flow area that the flow area of interlayer is greater than 4 cun;
2) between inner ring and gas phase swivel joint, be formed for the liquid channel that liquid phase is passed through, liquid channel adopts side seal, and the contact surface that left pipe and right pipe are pegged graft is guiding surface and adopts radial seal structure, installation, maintenance convenience;
3) dimensioned accuracy requirement is reduced, if these two sealing surfaces all adopt side seal between the contact surface that left pipe, right pipe join and inner ring and flange, dimension precision requirement is very strict, otherwise one of them easily leaks; After changing this structure, dimensioned accuracy requirement can reduce, and the qualification 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 spilling is also to leak into liquid channel, by liquid channel, flow in handling equipment, can not evaporate in atmosphere, avoid causing potential safety hazard.
