Problems solved by technology
Existing pressure regulators are usually detected by the pressure equalization method, and the pressure difference measured by the pressure difference sensor is used to determine whether the pressure regulator is qualified. At present, the reading of the pressure difference is usually obtained by manual reading, usually many Only a small amount of products are unqualified, but the inspectors need to check the differential pressure value of each product, which cannot automatically prompt and detect the unqualified parts of the product, and the detection efficiency is low

Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 As shown, a pressure regulator air tightness automatic detection system, including a main controller module, is characterized in that: the main controller module is connected with a differential pressure sensor, a touch screen control panel and an alarm module, and the main control module An A / D conversion module is connected between the sensor module and the differential pressure sensor. Input the pressure difference between the pressure regulator to be tested and the standard pressure regulator collected by the differential pressure sensor into the main controller module, and compare the collected value with the value set through the touch screen control panel. When the pressure regulator is unqualified, the detection personnel will be prompted through the alarm module, and each detected differential pressure value can be displayed on the tou...

The invention discloses an automatic airtightness detection system for a voltage regulator. The automatic airtightness detection system comprises a main controller module connected with a differential pressure sensor, a touch screen control panel and an alarming module. The invention solves the problem in the prior art that the efficiency in detecting the airtightness of a voltage regulator is low; and the pressure difference between a to-be-detected voltage regulator and a standard voltage regulator, acquired by the pressure difference transducer, is input into the main controller module, the acquired value and the set value are compared, and when ineligibility of the to-be-detected voltage regulator is discovered, the detection personnel is prompted by the alarming module, so that the detection efficiency is improved.
Description
technical field [0001] The invention relates to a pressure regulator air tightness automatic detection system, which belongs to the technical field of pressure regulators. Background technique [0002] The airtightness of the pressure regulator is a very important parameter index, and the test of the airtightness of the pressure regulator before leaving the factory is a very critical process. Existing pressure regulators are usually detected by the pressure equalization method, and the pressure difference measured by the pressure difference sensor is used to determine whether the pressure regulator is qualified. At present, the reading of the pressure difference is usually obtained by manual reading, usually many Only a small number of products are unqualified, but the inspectors need to check the differential pressure value of each product, which cannot automatically prompt and detect the unqualified parts of the product, and the detection efficiency is low.
