Vacuum-degree detection device of vacuum thermal-insulation plate

Abstract

The invention provides a vacuum-degree detection device of a vacuum thermal-insulation plate, which can solve the problem in the prior art that the vacuum thermal-insulation plate durability can not be evaluated as the service life can not be predicated due to the incapability of detection of the vacuum degree of the vacuum thermal-insulation plate. The technical scheme is as follows: the vacuum-degree detection device of the vacuum thermal-insulation plate comprises a machine table, a vacuum cavity and a vacuum-pumping pipeline; the upper part of the machine table is hinged with a cover body, and damaging device is arranged on the cover body; the vacuum cavity comprises a bottom plate, a test groove is arranged at the upper part of the bottom plate, a lifting seat used for bearing the to-be-tested vacuum thermal-insulation plate and an airbag located at the lower part of the lifting seat are arranged inside the test groove, and a detection device is arranged at the lower part of the bottom plate; the vacuum-pumping pipeline comprises a first pipeline communicated with the vacuum cavity and the vacuum-pumping device and a second pipeline communicated with the airbag and the vacuum-pumping device. The vacuum-degree detection device can detect the vacuum degree in the vacuum thermal-insulation plate, predicts the service life of the vacuum thermal-insulation plate, is used for evaluating the durability of the vacuum thermal-insulation plate and ensures the energy-saving efficiency of the energy-saving building.

Description

technical field [0001] The invention belongs to the field of testing equipment for building thermal insulation materials, and in particular relates to a vacuum degree testing equipment for vacuum insulation panels. Background technique [0002] Nowadays, people attach great importance to building energy conservation, and various energy-saving materials or structures emerge in an endless stream. Vacuum heat insulation is a very efficient heat insulation method. The gas remaining in the heat insulation space is removed by vacuuming, so that various heat transfer paths caused by the gas are eliminated, so that the heat insulation effect of vacuum heat insulation is much better than that of Other traditional insulation materials. The application of vacuum insulation panels using this technology in the field of building thermal insulation is still in its infancy. At present, only the European construction industry has this kind of thermal insulation material application in the w...
