Constant-temperature high-pressure water-bath kettle

Abstract

The invention discloses a constant-temperature high-pressure water-bath kettle. The constant-temperature high-pressure water-bath kettle is characterized by including a housing, a kettle cover, a water storage tank, a bottom groove, a ball float valve water-level control switch, a pressure limiting valve, a heating device and a water outlet pipe. The kettle cover is arranged on the top of the housing, and a closed space of the water-bath kettle is defined by the kettle cover and the housing. The water storage tank and the bottom groove are in the closed space, and are communicated by the ball float valve water-level control switch, and the height of the water storage tank is higher than that of the bottom groove. The heating device is arranged on the bottom of the bottom groove. While the water outlet pipe is communicated with the bottom of the bottom groove, and passes through the housing to lead to the outside. In addition, the pressure limiting valve is arranged on the kettle cover. When the constant-temperature high-pressure water-bath kettle is used for an actual density test, the constant-temperature high-pressure water-bath kettle has the advantages of convenient operation and accurate liquid level control, and can ensure that the actual density test is successfully and efficiently completed, and test results are accurate and practical.

Description

technical field [0001] The invention relates to a water bath, in particular to a constant temperature and high pressure water bath, and belongs to the technical field of testing instruments for detecting the true density of powder solids. Background technique [0002] When the traditional water bath is in use, the operating temperature does not exceed 100°C, the pressure is atmospheric pressure, and during the entire water bath process, special guards are required to add water from time to time. Therefore, the measurement efficiency is low, the error is large, and the operation is troublesome. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a constant temperature and high pressure water bath that does not need special guards when in use, can automatically control the liquid level, and can be applied to the experimental conditions of the true density test exceeding atmospheric pressure...

AI Technical Summary

Problems solved by technology

[0002] When the traditional water bath is in use, the operating temperature does not exceed 100°C, and the pressure is atmospheric pressure. During the entire water bath process, someone needs to be guarded and add water from time to time. Therefore, the measurement efficiency is low, the error is large, and the operation is troublesome.
