Description
Technical field
The utility model belongs to steel pipe welding detection technique field, specifically is a kind of hydrostatic testing machine face seals.
Background technique
Hydrostatic testing machine is to be used for the welded steel pipe of being produced is carried out the equipment that pressure-bearing is tested; Purpose is a check weld seam welding quality; Thereby judge whether steel pipe meets relevant criterion and satisfy user's needs, is a kind of quality test equipment, be fit to all kinds of welded tube manufacturing enterprise.At present; For the heavy caliber welded tube; Generally adopt the steel pipe end face seal to carry out the hydrostatic test both at home and abroad, end-face seal ring is the ring-type pattern, and the seal ring means of fixation is an inside and outside pair of COMPRESSIONTYPE; But a kind of seal ring can only be fit to the diameter of steel tube of a kind of specification or two kinds of specifications, so need the multi-sizeization of seal ring.When carrying out pressure test, steel pipe contact seal ring position remains unchanged basically when testing at every turn, under the high pressure effect simultaneously; Because seal ring and steel pipe tight friction; And the roughness ratio of steel tube surface is bigger, and seal ring is prone to cut off damage like this, has shortened working life; Improve the frequency of maintenance greatly, reduced the working efficiency of hydrostatic testing machine.
The model utility content
The utility model technical problem to be solved be short to end-face seal ring working life in the existing technology, specification is many, the inefficiency of hydrostatic testing machine and a kind of hydrostatic testing machine face seals is provided.
For the technical problem that solves the utility model adopts following technological scheme:
A kind of hydrostatic testing machine face seals; Comprise motor reducer, sealing seat, sealing plate and driving mechanism composition, said sealing plate is installed in the sealing seat surface, and said sealing seat is fixed on the frame; Said motor reducer is fixed on the frame; Described driving mechanism is on frame, to establish a driving shaft and a driven shaft, and said driving shaft one end is connected with motor reducer, and first eccentric bushing is housed on the driving shaft; Second eccentric bushing is housed on the said driven shaft, and said second eccentric bushing connects a connecting plate, and said connecting plate lower end is provided with hinge, and said hinge is connected with sealing seat; Establish a drive sprocket on the said driving shaft, establish a driven sprocket on the said driven shaft, be connected through drive chain between drive sprocket and the driven sprocket.
Said sealing seat is an annular slab.
Said sealing plate is used pressing plate, is bolted to said sealing seat surface.
The hydrostatic testing machine face seals of the utility model has adopted the major diameter sealing plate, has satisfied the hydrostatic test of different size steel pipe.Motor reducer is installed on frame, and after first steel pipe suppressed, motor reducer drove the eccentric bushing parts; Drive sealing seat and make rotary oscillation; With angle of sealing seat rotary oscillation, make position and first steel pipe of the end face contact seal plate of next root steel pipe suppress back steel pipe contact position and stagger, avoided many steel pipes to repeat to contact at the sealing plate same position; Thereby it is excessive to have alleviated the sealing plate local compression; Slowed down sealing plate fatigue ruption, prolonged sealing plate working life, reduced cost.The utility model is simple in structure, reliable, easy to operate simultaneously, after increasing encoder on the speed reducer output shaft, can realize automation control.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
Like Fig. 1,2, shown in 3; A kind of hydrostatic testing machine face seals comprises motor reducer 1, sealing seat 7, sealing plate 8 and driving mechanism composition, and driving mechanism is fixed on the frame 10; Driving mechanism is by driving shaft 5, drive sprocket 4; Driven sprocket 11, driven shaft 12, drive chain 2 is formed.Sealing seat 7 is a major diameter annular slab, and sealing seat 7 is fixed on the frame 10.Sealing plate 8 usefulness pressing plates 14, bolt 15 are installed in sealing seat 7 surfaces, only need unclamp pressing plate 14 when changing different size sealing plate 8, bolt 15 gets final product.Sealing plate 8 only need satisfy a kind of of maximum diameter of steel tube in theory, but for the manufacturability of improving sealing plate 8 be user-friendly to, reduce the wastage, generally be divided into two grades or third gear according to diameter of steel tube.Because sealing plate 8 is adopted in the present technique end face seal, avoided traditional end face seal structure seal ring to adopt the loaded down with trivial details structure of interior outer press ring, simplify the structure, reduced cost, be convenient to make and assembling.Motor reducer 1 is fixed on the frame 10, and a driving shaft 5 and a driven shaft 12 are installed on frame 10, and driving shaft 5 one ends are connected with motor reducer 1, and first eccentric bushing 6 is housed on the driving shaft 5; Second eccentric bushing, 13, the second eccentric bushings 13 are housed on the driven shaft 12 connect a connecting plate 3, connecting plate 3 lower ends are provided with hinge 9, and hinge 9 is connected with sealing seat 7; Drive sprocket 4 is installed on the driving shaft 5, driven sprocket 11 is installed on the driven shaft 12, be connected through drive chain 2 between drive sprocket 4 and the driven sprocket 11.Promptly first eccentric bushing 6 and second eccentric bushing 13 and sealing seat 7 form one group of four connecting rod parallel-crank mechanism, and oscillating motion is done by mechanism under the driving of motor reducer 1.
In use, after first steel pipe suppressed, when motor reducer 1 drives driving shaft 5 rotations; Drive driven sprocket 11 through drive chain 2 and begin rotation, make driven shaft 12 rotations, rotate with maximum eccentricity amount thereby drive eccentric bushing; With angle of sealing seat 7 rotary oscillations, drive sealing seat 7 and sealing plate 8 and do whole swing, make sealing plate 8 depart from original central position; Steel pipe end face and sealing plate 8 contact positions squint, and make position and first steel pipe of the end face contact seal plate 8 of next root steel pipe suppress back steel pipe contact position and stagger, and have avoided many steel pipes to repeat to contact at the sealing plate same position; Thereby it is excessive to have alleviated the sealing plate local compression; Slow down the fatigue ruption of sealing plate 8, prolonged the working life of sealing plate 8, reduced cost.
In addition; What the present technique scheme adopted the kind of drive is the sprocket wheel chain, also can adopt the belt wheel kind of drive, and dynamical element also can adopt oil hydraulic motor etc.; After driving shaft 5 or driven shaft 12 ends are equipped with encoder; Can realize automation control, through the programming of numerical control system, the just displacement of the plate of control end face seal easily 8.
