Embodiment 1

[0065] A leak detection device for an electromechanical valve 100 includes a mounting base plate 1, a blocking assembly and an air pressure detection assembly.

[0066] The installation substrate 1 has a detection position for placing the electromechanical valve 100 to be detected. The detection position is only for positioning the position of the plugging assembly, that is, after the electromechanical valve 100 is moved to the detection position, it is convenient for the plugging assembly to move out of the electromechanical valve 100. Gas port 101 is blocked.

[0067] The blocking component is arranged on the installation substrate 1, and the air outlet 101 of the electromechanical valve 100 located at the detection position is blocked, and an inflation channel is arranged inside the blocking component;

[0068] The air port of the air pressure detection component is connected to the air charging channel. The air pressure detection component includes an air pump and a pressu...

Embodiment 2

[0071] In the above embodiments, the air outlet 101 needs to be blocked by a plugging component. At present, manual plugging is mostly used. This embodiment provides an automatic sealing structure. The plugging component includes a hollow shaft 2 and a hollow tie rod 3 And rubber sealing ring 4;

[0072] The hollow shaft 2 has a first end and a second end, which is a straight cylindrical structure. The hollow shaft 2 is provided with a first axial through hole inside. The hollow shaft 2 is connected to the mounting substrate 1, and the central axis of the hollow shaft 2 is The central axis of the air outlet 101 coincides, and the first end of the hollow shaft 2 is provided with a first protrusion 21;

[0073] The first protrusion 21 can be a ring coaxial with the hollow shaft 2 .

[0074] The hollow tie rod 3 has a first end and a second end, which is a straight cylindrical structure. The inside of the hollow tie rod 3 is provided with an axial second through hole 32. The hol...

Embodiment 3

[0083] Because the diameter of the air outlet 101 of the electromechanical valve 100 is small, the diameter of the hollow tie rod 3 should not be too large. If the hollow tie rod 3 is directly connected to the moving end of the first linear moving assembly 5, it may cause a connection with the air pump. The structure is unstable, so the blocking assembly in this embodiment also includes a connecting block 6 .

[0084] For the convenience of description, several faces of the connecting block 6 are respectively named as the first end face, the second end face and the side (the side can be a plurality of straight faces and / or curved faces, and can also be a cylindrical face), and the position is limited: The first end face of the connection block 6 is arranged parallel to the second end face of the connection block 6, and the side surface of the connection block 6 is vertically arranged with the first end face of the connection block 6;

[0085] The second end of the hollow tie r...

Abstract

The invention discloses an electromechanical valve sealing performance detection device and method suitable for Internet of Things intelligent manufacturing, and the device comprises a mounting substrate, a plugging assembly, and an air pressure detection assembly, and the mounting substrate is provided with a detection position for placing a to-be-detected electromechanical valve; the blocking assembly is arranged on the mounting substrate and blocks an air outlet of the electromechanical valve located at the detection position, and an inflation channel is formed in the blocking assembly; an air port of the air pressure detection assembly communicates with the inflation channel, the air pressure detection assembly comprises an air pump and a pressure gauge, and the pressure gauge is arranged between an air outlet of the air pump and the plugging assembly and used for detecting the internal air pressure of the electromechanical valve; according to the invention, the plugging assembly is arranged to plug the air outlet of the electromechanical valve, then air is pumped into the sealed electromechanical valve through the air pump, and the air pressure in the electromechanical valve is measured through the pressure gauge, so that the sealing detection of the electromechanical valve is realized.

Description

technical field [0001] The invention relates to the field of electromechanical valve production, in particular to an electromechanical valve leak detection device and method suitable for intelligent manufacturing of the Internet of Things. Background technique [0002] The gas meter electromechanical valve needs to be installed on the natural gas pipeline. Therefore, after the main production of the electromechanical valve is completed, it needs to be tested for sealing to ensure that there will be no natural gas leakage during use. At present, most of the testing The method is to detect manually, which is inefficient and cannot be installed in an electromechanical valve production line. Contents of the invention [0003] The technical problem to be solved by the present invention is that the current electromechanical valve airtightness detection method is not compatible with the electromechanical valve production line. The problem of seal detection. [0004] The present...
