Description
Technical field
The utility model relates to the Sealing field of container, is specially a kind of change diameter seal.
Background technique
For the reaction environment medium to the material extending Effect on Performance, a lot of tension tests are to carry out allowing tensile sample be in certain surrounding medium, as the slow tension test under the corrosive environment, saturated H
2Constant load test in the S solution etc.Usually, this surrounding medium is to be stored in the little container, the gauge length section and the changeover portion of tensile sample are arranged in surrounding medium, thereby the two ends of tensile sample are passed container and are connected realization with clamp holder to its loading, Figure 1 shows that the mode that seals between a kind of typical environment container and the tensile sample, promptly outside sample 11, put O RunddichtringO 13, sample 11 inserted adds a cover blind nut 12 behind the container cinclides again and tighten and sealed, subsequently at the two ends of sample 11 loading force F to implement tension test.Yet, because the size restrictions of mother metal during the tensile sample sampling, as thin walled tube, thin plate etc., can not require to obtain full size bar according to the routine of test, often the two ends diameter of sample is less than standard measure, in order to test, the sample jointing diameter of environment container must diminish, and then changes the entire environment container.Tensile sample for different-diameter just needs to prepare multiple environment container like this, and is very inconvenient.
Summary of the invention
In order to overcome the defective of prior art, a kind of sealing tool that can be applicable to the tensile sample of multiple different-diameter is provided, the utility model discloses a kind of change diameter seal.
The utility model reaches goal of the invention by following technical solution:
A kind of change diameter seal, comprise little O RunddichtringO, conversion cutting ferrule, blind nut and big O RunddichtringO, sample is inserted in the through hole of container wall, and the two ends of sample are with little O RunddichtringO, conversion cutting ferrule, blind nut and big O RunddichtringO respectively and are stamped blind nut, it is characterized in that:
Little O RunddichtringO, blind nut and big O RunddichtringO respectively have two, and transition card is with four,
The conversion cutting ferrule is flange-like, the center has through hole, through hole and sample form Spielpassung or transition fit, through hole is embedded in little O RunddichtringO, conversion cutting ferrule flange is with big O RunddichtringO outward, and the external diameter and the through hole on the container wall on conversion cutting ferrule chassis form Spielpassung or transition fit, and two conversion cutting ferrules are respectively overlapped at the two ends of sample, these two conversion cutting ferrules are staggered relatively with the chassis
Blind nut is flange-like, and the center has through hole, and the flange of through hole and conversion cutting ferrule forms Spielpassung or transition fit, and the blind nut flange has been attacked screw thread outward, and between the through hole on the container wall by being threaded.
Described change diameter seal is characterized in that: conversion cutting ferrule via bottoms is cone-shaped, and the inclined-plane of the conical surface and the angle of bottom surface are between 30 °～60 °, and little O RunddichtringO is embedded in the conical surface.
When the utility model uses, earlier sample is inserted in two relative on container wall through holes, two conversion cutting ferrules are staggered relatively with the bottom surface, outside a conversion cutting ferrule flange, put big O RunddichtringO, through hole at another conversion cutting ferrule is embedded in little O RunddichtringO, then two transition card covers are enclosed within an end of sample, the conversion cutting ferrule that flange is with big O RunddichtringO outward is inserted in sample earlier, at last blind nut is overlapped the flange of changing cutting ferrule and screws in the hole of container wall and tighten.The other end of sample also is inserted in little O RunddichtringO, conversion cutting ferrule and big O RunddichtringO with identical method, and tightens blind nut.Big O RunddichtringO is squeezed between conversion cutting ferrule and the container wall, is used to change the sealing between cutting ferrule and the container; Little O RunddichtringO is squeezed between two conversion cutting ferrules, is used to change the sealing between cutting ferrule and the sample.When the blind nut on the container was tightened, little O RunddichtringO and big O RunddichtringO were squeezed, and play the effect of sealing.
The beneficial effects of the utility model are: suitable structures is simple, scope is wide, good sealing effect.

Embodiment
Below further specify the utility model by specific embodiment.
A kind of change diameter seal, comprise little O RunddichtringO 1, conversion cutting ferrule 2, blind nut 3 and big O RunddichtringO 5, as shown in Figure 2, concrete structure is: sample 7 is inserted in the through hole of container wall 4, and the two ends of sample 7 are with little O RunddichtringO 1, conversion cutting ferrule 2, blind nut 3 and big O RunddichtringO 5 respectively and are stamped blind nut 3.Little O RunddichtringO 1, blind nut 3 and big O RunddichtringO 5 respectively have two, and conversion cutting ferrule 2 has four.Conversion cutting ferrule 2 is flange-like, as shown in Figure 3, the center has through hole, through hole and sample 7 form Spielpassung or transition fit, through hole is embedded in little O RunddichtringO 1, and conversion cutting ferrule 2 flanges are with big O RunddichtringO 5 outward, and the external diameter and the through hole on the container wall 4 on conversion cutting ferrule 2 chassis form Spielpassung or transition fit, two conversion cutting ferrules 2 are respectively overlapped at the two ends of sample 7, and these two conversion cutting ferrules 2 are staggered relatively with the chassis.Blind nut 3 is flange-like, and the center has through hole, and the flange of through hole and conversion cutting ferrule 2 forms Spielpassung or transition fit, and blind nut 3 flanges have been attacked screw thread outward, and between the through hole on the container wall by being threaded.
During use, earlier sample 7 is inserted in two relative on the container wall 4 through holes, two conversion cutting ferrules 2 are staggered relatively with the bottom surface, outside conversion cutting ferrule 2 flanges, put big O RunddichtringO 5, through hole at another conversion cutting ferrule 2 is embedded in little O RunddichtringO 1, then two conversion cutting ferrules 2 are enclosed within an end of sample 7, the conversion cutting ferrule 2 that flange is with big O RunddichtringO 5 outward is inserted in sample 7 earlier, at last blind nut 3 is overlapped the flange of changing cutting ferrule 2 and screws in the hole of container wall and tighten.The other end of sample 7 also is inserted in little O RunddichtringO 1, conversion cutting ferrule 2 and big O RunddichtringO 5 with identical method, and tightens blind nut 3.Big O RunddichtringO 5 is squeezed between conversion cutting ferrule 2 and the container wall 4, is used to change the sealing between cutting ferrule and the container; Little O RunddichtringO 1 is squeezed between two conversion cutting ferrules, is used to change the sealing between cutting ferrule and the sample.When the blind nut on the container 3 was tightened, little O RunddichtringO 1 and big O RunddichtringO 5 were squeezed, and play the effect of sealing.
Because little O RunddichtringO 1, conversion cutting ferrule 2, big O RunddichtringO 5 can touch testing liquid or gas medium in the container, so conversion cutting ferrule 2 needs to adopt corresponding corrosion-resistant material, as teflon, little O RunddichtringO 1 and big O RunddichtringO 5 also adopt corresponding corrosion-resistant material, as adopt acid resistance O type circle for acid test solution.
