Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
According to Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, the U-shaped ripple volume compensator of a kind of thin wall multi-layer of the utility model, it comprises housing 1, upper saw pulley 6, guide rail 7, form 10, described housing 1 top is provided with respirating tube 4, bottom is provided with equipment connecting tube 9, equipment connecting tube 9 is connected with medium container by flexible pipe, described housing 1 both sides are provided with guide rail 7, top is provided with upper cover 2, in housing 1, be packaged with ripple compensation element 8, ripple compensation element 8 is provided with upper head plate 12 and lower end sheet 13, ripple compensation element 8 and upper head plate 12 and lower end sheet 13 are welded into seal container, close seal container was connected with equipment container by equipment connecting tube 9, in order to prevent occurring that post unstability manifests in working procedure, on upper head plate 12, be provided with the polyurethane upper saw pulley 6 of making and the guide rail 7 that is fixed on housing 1 both sides, upper saw pulley 6 is stuck in the interior easy on and off guiding of guide rail 7, when the medium temperature in equipment raises or reduces, guide wheel 6 drives upper cover 12 to slide up and down in guide rail 7, the ripple compensation element 8 of compensator is stretched or compressed, described ripple compensation element 8 is bilayer or multiple layer metal thin-wall barrel, has increased the flexibility of cylindrical shell.
The barrel of ripple compensation element 8 cylindrical shells described in the utility model is the U-shaped bellowss of many ripples; Described ripple compensation element 8 adopts Stainless Sheet Steel to make; The profile of described ripple compensation element 8 cylindrical shells is circle or round rectangle bellows, and circular and fillet has guaranteed circumferential flexible conformity; Described housing 1 top is provided with respirating tube 4, and bottom is provided with equipment connecting tube 9, and equipment connecting tube 9 is connected with medium container by flexible pipe, during use, screw plug 3 is unclamped, and air body is discharged from outlet pipe 5, when medium 11 is full of, again screw plug 3 is tightened to sealing.
The utility model for have medium temperature change cause volume-variation equipment or device, when the medium temperature in equipment raises, medium generation volumetric expansion, upper saw pulley 6 drives upper head plate 12 in guide rail 7, ripple compensation element 8 is upwards stretched, medium in equipment enters in compensator by equipment connecting tube 9 import through the flexible pipe being connected with equipment, and the ripple compensation element 8 of compensator is stretched; When the medium temperature in equipment reduces, medium volume-diminished in equipment, upper saw pulley 6 drives upper head plate 12 in guide rail 7, by ripple compensation element 8 to lower compression, form parital vacuum state, at this moment (respirating tube 4 communicates with atmosphere all the time) compression under atmospheric effect of the medium in ripple compensation element 8 in compensator, is back in equipment again the medium process in compensator equipment connecting tube 9 through flexible pipe.Expand with heat and contract with cold the produced stress of the medium 11 of having eliminated like this equipment or device during due to temperature variation, guaranteed in equipment that medium 11 is all the time in seal container simultaneously, do not contact with air, avoided medium 11 to absorb moisture or the impurity of air, guaranteed the purity of medium 11, also avoid medium 11 to be oxidized in air and go bad, the equipment that effectively guarantees is normally worked, and has eliminated the generation of fault.
The utility model is U-shaped because bellows-shaped has adopted, crest corner is curved, increased the stability of ripple compensation element 8, so crest and trough keep arc when elongating or shortening, the concentrated stress that the crest of ripple and trough produce is little, has increased elasticity and the extending amount of ripple compensation element 8, increased fatigue life, while elongating or shortening, needed power is just very little simultaneously, that is, the power being added on equipment is very little; Overcome the weakness of the large and poor stability of individual layer ripple compensation element rigidity.Owing to having adopted bilayer or multilayer thin-walled to make ripple compensation element 8, it is flexible, and stability is strong, and ripple compensation element 8 is difficult for damaged.
The utility model can be observed by form 10 liquid level of the medium 11 in compensator, in a compensator, according to the size of compensation rate, can be comprised of one or more ripple compensation elements 8 that interconnect.
