The built-in vacuum degree detecting device for the vacuum insulation board has the advantages that vacuum degree in the vacuum insulation board can be detected in real time via the detecting device, and product quality can be ensured; structure is simple, and operation is easy; and during detection via the detecting device, the vacuum insulation board can be placed in the vacuum chamber, so that vacuum insulation boards with any surface can be detected.
Description
Technical field
The utility model relates to a kind of vacuum-ness detecting device of built-in vacuum heat-insulating plate, is mainly used in the vacuum tightness that detects vacuum heat-insulating plate in the production of vacuum heat-insulating plate.
Background technology
Vacuum heat-insulating plate is based on the vacuum insulation principle, realizes reducing convection current and radiation heat transfer by improving in the plate vacuum tightness and filling to greatest extent with the sandwich layer thermal insulation material.Coefficient of heat conductivity can reach 0.003W/ (mK)～0.004W/ (mK).At present general detection mode is to come the whether qualified of qualitative product quality by the coefficient of heat conductivity that heat conducting mode is measured vacuum heat-insulating plate.But the product internal vacuum there is not the method for inspection accurately.
The quality of core has determined the serviceable life of STP plate to a certain extent, and more satisfactory vacuum heat-insulation board core material is wanted porous surface, is evenly distributed, such core vacuumizes the time ratio and is easier to, exhaust vacuum internal vacuum height later on, also do not have air in the future and overflow, can increase greatly serviceable life; High air blocking thin film has aluminium foil and other materials to be composited, its quality is the most obvious to the influence of production board, aluminium foil itself is to have certain ventilative and water permeability, if the aluminium foil of selecting for use is ventilative and water permeability than higher, the serviceable life of production board can be very not high; The placement of getter mainly is in order to guarantee better vacuum tightness in the plate, to adsorb owing to the unnecessary gas that permeates or material outgassing produced, infiltrating the interior aqueous vapor molecule of plate and then adsorbed to fall by drying agent, to guarantee the serviceable life of STP plate.
But As time goes on, core itself can discharge certain gas, and the choke film also inevitably passes through the micromolecule of some aqueous vapors or other gases.The detection method of this vacuum heat-insulating plate internal vacuum, the vacuum tightness of detection vacuum heat-insulating plate that can be real-time is guaranteed the quality of product.
Summary of the invention
The utility model purpose provides a kind of vacuum-ness detecting device of vacuum heat-insulating plate, with solve that prior art exists can not be real-time the vacuum tightness of detection vacuum heat-insulating plate, complex structure is not allowed easy-operating problem.
The technical solution of the utility model is: a kind of vacuum-ness detecting device of built-in vacuum heat-insulating plate, it is characterized in that, comprise vacuum chamber, laser range finder, vacuum extractor and vacuum meter, at the top of vacuum chamber end laser range finder and vacuum meter are installed, bottom at vacuum chamber is provided with bottom, be provided with sealing gasket between the bottom of bottom and vacuum chamber, the inlet of vacuum extractor is connected with vacuum chamber.
Described vacuum extractor is composed in series by diffusion pump and lobe pump, and the inlet of diffusion pump is connected with vacuum chamber, and the diffusion delivery side of pump is connected with the inlet of lobe pump.
Described vacuum chamber is a square or cylindrical, and size can be held the vacuum heat-insulating plate of 40*40cm; This vacuum chamber is made by stainless steel or ABS plastic.
The utility model has the advantages that: the pick-up unit of this vacuum heat-insulating plate internal vacuum, the vacuum tightness of detection vacuum heat-insulating plate that can be real-time is guaranteed the quality of product; Simple in structure, operation easily.During this device to test vacuum heat-insulating plate is placed in the vacuum chamber, can detect the vacuum heat-insulating plate on any surface.

Fig. 1 is the structural representation of an embodiment of the present utility model
Embodiment
Referring to Fig. 1, the vacuum-ness detecting device of a kind of built-in vacuum heat-insulating plate of the utility model, it is characterized in that, comprise vacuum chamber 3, laser range finder 2, vacuum extractor and vacuum meter 1, at the top of vacuum chamber 3 end laser range finder 2 and vacuum meter 1 are installed, be provided with bottom 8 in the bottom of vacuum chamber 3, be provided with sealing gasket 7 between the bottom of bottom 8 and vacuum chamber 3, the inlet of vacuum extractor is connected with vacuum chamber 3.
Described vacuum extractor is composed in series by diffusion pump 4 and lobe pump 5, and the inlet of diffusion pump 4 is connected with vacuum chamber 3, and the outlet of diffusion pump 4 is connected with the inlet of lobe pump 5.
Test according to following steps during use:
(1) with vacuum extractor vacuum chamber 3 is vacuumized, and detect vacuum tightness in the vacuum chamber 3 with vacuum meter 1.
(2) laser range finder 2 testing laser are put the distance L of the choke membrane plane of vacuum heat-insulating plate 6 upper surfaces, when distance L changes, write down the vacuum tightness of this moment vacuum chamber, are the practical vacuum degree of vacuum heat-insulating plate 6.
Principle of work is: after vacuum heat-insulating plate was vacuumized, the pressure in the vacuum heat-insulating plate was lower than atmospheric pressure, and the choke film of vacuum heat-insulating plate is pressed in the core surface by atmospheric pressure, combines closely.When vacuum heat-insulating plate is placed in the vacuum chamber, and vacuum chamber vacuumized, when ambient pressure is consistent with the pressure of vacuum heat-insulating plate air pressure inside generation to the pressure of vacuum heat-insulating plate, the choke film can produce deformation, the distance detecting instrument detects deformation, the atmospheric pressure that reads vacuum chamber this moment is the air pressure of vacuum insulation intralamellar part, promptly records the vacuum tightness of vacuum heat-insulating plate.
