Problems solved by technology
[0003] The test results show that the tee pipe of the existing pressure gauge or pressure sensor will cause the characteristics of the refrigeration system to change, especially under the condition of continuous operation of the compressor, the pressure-enthalpy diagram of the refrigeration system will change greatly, resulting in The evaporating temperature rises and the condensing temperature falls, so that the original system characteristics cannot be measured correctly

The invention provides a testing tee-junction for a pressure sensor. The tee-junction comprises a connection pipe and a testing pipe, wherein testing holes running through the pipe wall are formed in the pipe wall of the connecting pipe; the lower end of the testing pipe is connected with the outer peripheral wall of the connecting pipe; the testing holes are formed in the inner peripheral wall of the testing pipe. According to the testing tee-junction for the pressure sensor, provided by the embodiment of the invention, as the testing holes running through the pipe wall are formed in the pipe wall of the connecting pipe, when the testing pipe is connected onto the pressure sensor, the inductive probe of the pressure sensor is in contact with the outer peripheral wall of the connecting pipe, and moreover, through using the testing holes to detect the pressure value of a refrigerating pipeline, the tee-junction is good in measuring effect.
Description
technical field [0001] The invention relates to a test tee for a pressure sensor. Background technique [0002] The state of the refrigerant in each feature point of the refrigeration system is determined by the two parameters of temperature and pressure, so it is necessary to collect and analyze the pressure and temperature values of each feature point of the refrigeration system at the same time, so as to optimize the matching of the entire refrigeration system. In a conventional refrigeration system, when testing the pressure of the characteristic point of the refrigeration system, a pressure gauge or a pressure sensor is often connected to the refrigeration system by using a three-way pipe. The main pipeline of the tee pipe is connected to the refrigeration system pipeline. The diameter of the test tube vertically connected to the main pipeline is the same or similar to that of the main pipeline. The test tube is connected to the main pipeline by welding or other metho...
