Abstract
The utility model relates to a sealing structure of a building material test-piece. In a penetration-resistance test, in order to prevent penetration from the lateral surface of the test-piece, wax is used for sealing, which is time-consuming and labor-consuming, and the sealing equality cannot be guaranteed absolutely. Therefore, the utility model provides an oil sac fastened-type sealing scheme, in particular to an oil sac fastened-type sealing structure of the penetration-resistance testing machine test-piece. The oil sac fastened-type sealing structure is characterized in that an oil sac, an O-shaped seal ring, a nut ring gasket and a fixing nut are arranged on the inner side surface of a test die sleeve in sequence from bottom to top, an oil sac bushing is arranged between the oil sac and the test die sleeve, the side surface of the oil sac is provided with an oil inlet, the outer side surface of the test die sleeve is provided with an oil inlet nozzle, and the oil inlet nozzle is communicated with the oil inlet and used for filling and discharging oil into the oil sac. According to the sealing structure disclosed by the utility model, after oil filling, the oil sac closely encircles the side surface of the test-piece; and the oil sac fastened-type sealing structure has the beneficial effects of time saving and labor saving, good sealing effect and accurate measured data and provides favorable conditions for automatic control.
Description
Technical field
The utility model relates to the material testing machine field, especially structural material testpieces sealing configuration.
Background technique
For structural material, particularly the performance test of coagulating cement soil block is very important, and permeability resistance is exactly one of the performance that wherein must test.The test features amount of being is big, requires data accurate.During test test specimen processed the cone of butt, require high-potting water from the upper bottom surface of test specimen toward the bottom surface infiltration, forbid infiltrating from the side; So must the side seal of test specimen at first extremely be melted heating paraffin fully, the conical surface with test specimen rolls a week in the paraffin that melts then; Form the paraffin sealing layer in the side of test specimen after cooling; Whole waxing process surpasses one hour, and it is loaded down with trivial details to work, and on sealing layer, possibly exist spilehole can not guarantee that sealing layer is definitely complete; So it is consuming time that existing technology exists the waxing process, the unwarrantable drawback of airtight quality.
The model utility content
The purpose of the utility model adopts and both saved time the oil sac fastening-type sealing configuration that sealing effect is good again for a kind of sealing of need not waxing is provided.
The technological scheme that realizes the utility model is following:
The oil sac fastening-type sealing configuration of impermeability test machine test specimen is equipped with oil sac fastening-type sealing configuration at impermeability test machine upper testing mould cover inner side surface, and its structure is for being equipped with oil sac at the die trial cover inner side surface relative with test specimen; The oil sac lining is housed between oil sac and inner side surface, the O RunddichtringO is housed on the oil sac lining, the nut lining ring is housed on the O RunddichtringO; Be die trial cover top on the nut lining ring, set screw nut is housed, the test specimen of in the die trial cover, packing into; Above test specimen, be die trial cover water cavity with the set screw nut hollow part; Have filler opening in the oil sac side, filler opening runs through oil sac lining and die trial cover side, and oil intake nozzle is housed outside the side.
Oil sac is processed by polyurethane.
The shape of oil sac is the tubular shape pouched, and middle oil-filled, oil sac internal diameter and test specimen external diameter are loose fit.
Be connected through the oil intake nozzle of the high-pressure oil passage on the impermeability test machine when the utility model uses, test specimen is packed into during die trial overlaps with die trial cover outer side surface, oil-filled in oil sac; Oil sac expands, and closes the oil sac seal arrangement switching-over locking solenoid valve on the oil circuit, and oil sac tightly surrounds the side of test specimen; With its sealing, carry out impermeability test then, after test is accomplished; Open the oil sac seal arrangement switching-over locking solenoid valve on the oil circuit; Oil in the oil sac is discharged, and unclamps test specimen, and test specimen is taken out from the die trial cover.
The utlity model has following beneficial effect:
1. the utility model is time saving and energy saving to the sealing of test specimen side, for test in enormous quantities provides advantage, has thoroughly abandoned being coated with lap sealant.
2. good sealing effect has prevented the leakage of test specimen side, and it is accurate to guarantee to record data.
3. changed the backward state of manual operation and supervision, created possibility, helped to realize automation control for realizing integrated management.
