Description
Technical field
The utility model belongs to measures the measuring strainometer of high pressure vessel internal strain, particularly a kind ofly is used for a kind of strainometer lead sealing equipment that high pressure vessel and boiler inner wall strain measurement are used.
Background technology
At present, when high pressure vessel is measured strain with strainometer, several lead-in wires that are distributed in the container must be drawn out to by the through hole on the container outside the container, therefore, place, lead outlet hole at container must install lead sealing equipment, uses the high pressure sealing that guarantees container, therefore requires to be loaded on the necessary compact conformation of lead sealing equipment on the container, sealing is reliable, and it is many and easy to loading and unloading etc. that the number of leads of drawing is wanted.At present, the lead sealing equipment structure of domestic design has rubber lead sealing equipment, rosin, vaseline packoff, conical surface seal device etc., wherein rosin, vaseline packoff are used comparatively extensive, its structure comprises flange form pigtail splice and stud bolt composition, be conical bore in the flange form pigtail splice wherein, installing dividing plate in the ring flange mouth spreads all on the separator face to have and can make the aperture of drawing; With ground of the lead-in wire in the container pass aperture on the dividing plate draw container outer after, in conical bore, fill the fixed bed of rosin, vaseline.This rosin, vaseline packoff and container installation requirement height, bearing capacity is little, only is applicable to the occasion that 10Mpa is following, and can not reuses.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only reasonable in design, compact conformation, simple and practical, both improved the lead-in wire sealing intensity, bearing capacity is big, increase number of leads again, and have easy to loading and unloading, reusable, cost is low, and uses a kind of very easily strainometer lead sealing equipment.
The purpose of this utility model is to adopt following technical scheme to realize: described strainometer lead sealing equipment, comprise the strainometer lead-in wire, it is characterized in that: the lead hole place at container connects lead sealing equipment, described lead sealing equipment is by the lead-in wire seal head, combination sealing packing ring and sealant layer are formed, one section of the lead-in wire seal head is external thread section, the heel of external thread section is provided with step, between step and container, be equiped with the combination sealing packing ring, in the lead-in wire seal head is that the big footpath of taper hole ecto-entad is processed with conical bore with the threaded port, in conical bore, be filled with the fixedly sealant layer of strainometer lead-in wire, be arranged with conical bore in the body of the lead-in wire seal head between the path end face of lead-in wire seal head and conical bore and be communicated with the lead-in wire branched hole that joins, be filled with the sealant layer that fixing strainometer goes between in each branched hole.
Described sealant layer is the epoxy resin glue-line.
The quantity of described lead-in wire branched hole is at least two.
The utility model principle and operation are described below:
Because the end that the lead-in wire seal head in the utility model is connected with container is provided with conical bore, the other end is arranged with the lead-in wire branched hole more than two, and lead-in wire is drawn by the lead-in wire branched hole after penetrating lead-in wire seal head center circle taper hole, pours into fluid sealant then.During use: the combination sealing packing ring is installed on the step end face of thread root, the strainometer lead-in wire that will water good lead-in wire seal head then penetrates in the container through hole, be connected with container by screw thread, and this structure easy accessibility, reusable.Taper hole and the lead-in wire branched hole more than two are adopted in the inside of lead-in wire seal head, can penetrate lead-in wire very easily, increase bearing capacity and reduced installation difficulty, compare this device number of leads with other packoff and increased by 40%, reduced the usage quantity of lead sealing equipment, improved the security of sealing property and use, maximum can be born the pressure of 28Mpa and do not had leakage.Combine the above technical scheme of being taked, realize the purpose of this utility model.
Compared with prior art, the utility model is not only reasonable in design, and compact conformation is simple and practical, both improved the lead-in wire sealing intensity, bearing capacity is big, increases number of leads again, and has easy to loading and unloading, reusable, cost is low, and uses advantages such as very convenient.
