Abstract

A dual-display vacuum display meter consists of a gas inlet pipe (1), a mechanical vacuum meter (2), a one-way floater (3), a connector (4), a hose (5), a pipe connecting plug (6), a U-shaped mercury vacuum meter (7), a connecting pipe I (8) and a connecting pipe II (9), wherein the connecting pipe I (8) and the connecting pipe II (9) are welded on the same side of the gas inlet pipe (1); the mechanical vacuum meter (2) is mounted on the connecting pipe II (9); the one-way floater (3) is mounted between the mechanical vacuum meter (2) and the connecting pipe II (9); the connector (4) is mounted on the connecting pipe I (8); the dual-display vacuum display meter is characterized in that the connector (4) is connected with the pipe connecting plug (6) through the hose (5); the pipe connecting plug (6) is inserted into the U-shaped mercury vacuum meter (7). The dual-display vacuum display meter detects gas pressure of equipment to be detected through the hose and the gas inlet pipe at the same time, and an average error value is used, so that a detected numerical value is more accurate.

Description

technical field [0001] The invention relates to a dual-display vacuum display gauge, which is especially suitable for occasions with high requirements for vacuum degree detection. Background technique [0002] In some occasions, when a single detection vacuum gauge is being tested, due to the structural characteristics of the vacuum gauge, it will be affected by the surrounding environment, and the display will be disordered. Some mechanical watches are not very accurate in displaying values ​​when in use. Contents of the invention [0003] In view of the above situation, the object of the present invention is to provide a dual-display vacuum display meter, which is to be equipped with an upper mechanical vacuum meter and a U-shaped mercury vacuum meter in series on the same side of the air intake pipe of the tested equipment. The gauge and the U-shaped mercury vacuum gauge complement each other to accurately display the detected pressure value. [0004] The technica...
