Embodiment Construction

[0024] Such as figure 1 As shown, a preferred embodiment of the present invention proposes a device for freezing an ice jacket in a water triple point bottle, comprising: a water tank for accommodating the water triple point bottle 7, arranged in the water tank, for The hanger 14 of described water triple point bottle 7 is installed, and is connected with described water tank, is used to provide constant temperature circulation cooling water in described water tank so that form ice jacket in described water triple point bottle 7 and reach water. A temperature control device with balanced coexistence of solid, liquid and gas.

[0025] Specifically, the water tank includes an inner tank body 1 and an outer tank body 2 set outside the inner tank body 1. The inner tank body 1 is a cylindrical sleeve with a diameter of 130-200 mm and a depth of 450- 500 mm; the outer tank body 2 is a cylinder or a square body, and there is a cavity between the outer tank body 2 and the inner tank ...

Abstract

The invention discloses a device for freezing an ice sleeve in a water triple point bottle. The device comprises a water tank, a suspension frame and a temperature control device, wherein the water tank is used for containing the water triple point bottle, the suspension frame is installed inside the water tank and used for installation of the water triple point bottle, and the temperature control device is connected with the water tank, is used for supplying constant-temperature circulating cooling water to the water tank, enables the ice sleeve to be formed inside the water triple point bottle, and achieves solid, liquid and gas three-phase equilibrium coexistence of water. According to the device, the freezing method is simple to operate, freezing processes are convenient, safe and reliable, operation personnel do not need to purchase liquid nitrogen or other low-temperature liquid, an ice machine, an ice crusher and a heat preservation barrel are not required to be manufactured, simultaneously, the operation personnel do not need to be trained professionally and have experienced operating skills, and the risk that the water triple point bottle can be damaged during the freezing processes does not need to be worried. The device can be suitable for triple point long-term reproduction preservation of temperature standard laboratory water, and is conducive to popularization of temperature fixed point quantity transmission.

Description

technical field [0001] The invention relates to the technical field of water triple point bottles, in particular to a device for freezing ice jackets in water triple point bottles. Background technique [0002] The triple point of water is a device that produces a constant thermodynamic temperature when the solid, liquid, and gas phases of water coexist in equilibrium, and its value is defined as 0.010°C. It is reproduced in a sealed glass vessel containing high-purity water (the isotopic composition of water is equivalent to that of ocean water), namely the triple point bottle of water. The water triple point bottle is one of the fixed-point devices for the verification benchmarks of thermometer verification institutions at all levels, standard platinum resistance thermometers, and standard mercury thermometers. Therefore, the correct reproduction and accurate measurement of the triple point of water is the key to the implementation of the 1990 International Temperature Sc...
