Abstract

The invention provides an automatic pressure tapping device, which comprises a cabinet body and a pressure tapping system arranged in the cabinet body, wherein the pressure tapping system comprises a pressure tapping pipeline, a measurement instrument, a solenoid valve control interface, a solenoid valve group and an instrument signal interface, wherein the pressure tapping pipeline and the solenoid valve control interface are respectively connected with the input end of the solenoid valve group; the output end of the solenoid valve group is connected with the measurement instrument; and the measurement instrument is connected with the instrument signal interface. the automatic pressure tapping device can move freely in a test area according to needs, the pressure tapping pipeline connection operation is simplified to the maximum degree, the pipeline and the cable number in the test area are simplified, the pressure tapping pipeline can be automatically controlled and switched according to a measurement instrument selected by a test person, and while the measurement data are observed in real time, the data are transmitted to a computer system in an electric signal mode.

Description

technical field [0001] The invention belongs to the technical field of truck air conditioners, and in particular relates to an automatic pressure taking device. Background technique [0002] Valve flow resistance test is a way to reduce valve flow resistance loss through product testing. The development of high-precision flow and flow resistance testing devices can provide reliable scientific data for valve product improvement and rational design of fluid engineering systems to reduce power consumption, select reasonable valves for industrial departments, and provide technical support for the development of new energy-saving products. The existing valve flow resistance test device is a high-precision and high-automation system designed for valve flow resistance test and supported by system software, covering detection, data acquisition, data processing and automatic control. In this system, the pre-valve pressure and post-valve pressure of the measured valve need to be conn...
