Problems solved by technology
[0004] The thermal conductivity tester mainly tests plastic, rubber, glass, fiberboard, benzene board, extruded board, foamed concrete, hollow glass, wood board, various insulation materials and other homogeneous plate materials, and can also measure granular materials, bulk materials, The thermal conductivity of various materials such as soft materials. The thermal coefficient tester can accurately detect the thermal conductivity of plate-shaped materials. Because of the different materials and specifications of plate-shaped materials, the thermal coefficient tester cannot effectively control the clamping force. There is a problem of damage caused by excessive clamping of the plate-shaped material, and it is inconvenient to remove the plate-shaped material from the thermal coefficient meter after measurement

The invention discloses a flat plate heat conductivity coefficient determinator for engineering inspection, which comprises an equipment box, hydraulic rods, a moving plate, a mounting plate, a cold plate, a limiting strip and a pull ring, the cold plate is arranged in the equipment box, the limiting strip is arranged at the opposite end of the cold plate, and the outer wall of the limiting strip is sleeved with a spring, the hydraulic rods are arranged in the two sides of the equipment box, a mounting plate is arranged at the opposite ends of the hydraulic rods, a stroke hole is formed in the mounting plate, a stroke groove is formed in the inner wall of the lower end of the equipment box, a moving plate is arranged in the stroke groove, a mounting groove is formed in one end of the moving plate, and a pull ring is arranged at an opening of the mounting groove, and an inhaul cable is arranged at one end of the pull ring. The hydraulic rods push the cold plate, springs contract in the extrusion process, limiting strips make contact with an induction plate, signals are transmitted to a controller, the hydraulic rod stops operating, plates of different materials and specifications are effectively clamped, the plates are taken out through a movable plate, and the plates are more convenient to store and take.
Description
technical field [0001] The invention relates to a thermal conductivity measuring instrument and the technical field, in particular to a flat plate thermal conductivity measuring instrument for engineering inspection. Background technique [0002] Engineering inspection refers to the inspection items stipulated in the national construction and acceptance specifications and quality standards, using the methods and means stipulated by the state to conduct quality inspections on sub-projects, sub-projects and unit projects, and compare them with the provisions of quality standards To determine whether the quality of the project meets the requirements, the thermal conductivity of the material needs to be tested during the process inspection. The thermal conductivity of different materials is different, and the thermal conductivity of the same material is related to its structure, density, humidity, temperature, pressure and other factors. [0003] Thermal conductivity is an impor...
