Description
Technical field
The present invention relates to the materials handling equipment field, in particular to a kind of swivel joint, comprise this swivel joint the handling arm, comprise the materials handling equipment of this handling arm.
Background technique
Fast development along with China's economy, rock gas has been subjected to more and more people's approval as a kind of novel clean energy resource, the city that the rock gas of take is main energy sources is more and more, the automobile that the rock gas of take is the energy is also more and more, the consumption of compressed natural gas and the quantity of gas station constantly increase, and for the mounting-and-dismounting device of compressed natural gas, are also increasing.Up to 25MPa, have the break danger of blast of reservoir vessel and conveyance conduit due to the pressure of compressed natural gas, it is also inflammable and explosive dangerous goods simultaneously, the danger of have burning, exploding.At present, the mounting-and-dismounting device of compressed natural gas is all to adopt flexible pipe.But, use external inlet hose to have following shortcoming: 1, operator are when the handling compressed natural gas, decontrol before operative installations and with after pack up flexible pipe, need 5 meters flexible pipes how long in tow to adjust the position of loading hatch in order to be connected with the compressed natural gas loading vehicles, because flexible pipe has certain hardness and weight, malfunction, increased operator's labor intensity; 2, with steel pipe, compare, the bearing capacity of flexible pipe is low, therefore, in handling compressed natural gas process, explosion sometimes occurs, reveals and causes security incident; 3, because flexible pipe and pipe joint adopt the mode of withholding, be connected, the pull-off phenomenon easily occurs in the two, so that the compressive resistance impact capacity is low; 4, flexible pipe in use, easily produces static, has the danger that produces fire and blast; 5, in use, due to the frequent retracting hose of needs, and the stand of compressed natural gas loading vehicles is fixing, so that flexible pipe will often pull and haul a man on the ground, with ground, produces friction and causes wearing and tearing; 6, in use, tiling is dilatory on the ground for flexible pipe, if with after forget and pack up, even can be injured by a crashing object and be rolled bad by vehicle; 7, flexible pipe in use, the acting in conjunction that be subject to the corrosion of inner rock gas and outside wind, Exposure to Sunlight, drenches with rain, easily aging, the life-span is short.External inlet hose, be only 6 months quality guarantee period, generally uses 1 year, do not allow to continue to use; 8, external inlet hose is expensive and need the cost foreign exchange, and working life, short shortcoming further increased again user cost, if long term purchase will increase national foreign exchange burden.
Because flexible pipe has the energy bending, often for delivery of fluid, comprise on the pipeline or equipment of liquids and gases, at present, the mounting-and-dismounting device of compressed natural gas (CNG) just adopts flexible pipe.In order to make the pipeline that steel pipe forms can be applicable to carry fluid, the pipeline transformation that just steel pipe need to be formed becomes can be movable and can adjust pipeline and import and export position, and universal method is the swivel joint joint steel pipe that use can mutually be rotated and can be sealed.The structure of the swivel joint used at present exists following shortcoming to be usually: 1, adopt two raceways and steel ball rotational structure: turning the two raceways of processing on core and shell, steel ball is installed in raceway, but because the difficulty of raceway processing is large, be difficult to arrive higher geometric accuracy and axial position dimensional accuracy, this structure has also been brought great inconvenience to the installation and removal of swivel joint; 2, edge face sealing member only is set one: the single-end face seal only is installed between the end face that turns core and flange gland, is only had one end face seal, sealing reliability is poor, once lose efficacy, will produce leakage; The seal groove of 3 Sealings be with contacted two part end faces of Sealing on processing seam form, end face is rough and uneven in surface, is difficult to improve surface flatness, the contact condition of Sealing and end face is bad; 4, for the manufacture of the material of swivel joint, do not heat-treat, hardness is too low, if use Austenitic Stainless Steel, heat treatment can not improve hardness yet.Although some material heat treatment can improve hardness, but have the defect of being out of shape, kinematic accuracy and robust motion are existed to adverse effect, also affect the dimensional accuracy of seal groove simultaneously, sealing is difficult to guarantee.Owing to there being the problems referred to above, current swivel joint can only can not be used for the gas materials handling equipment below 2MPa on pressurized gas equipment, particularly can not be applicable to the handling arm of pressure up to the compressed natural gas of 25MPa.
The pipeline problem that structural defect can't be loaded and unloaded compressed natural gas because swivel joint exists for only loading and unloading compressed natural gas by flexible pipe in prior art, be made by steel pipe, not yet propose effective solution at present.
