Problems solved by technology
[0003] At present, when detecting needle valves, the number of turns of the needle valve is generally adjusted manually. This manual adjustment method cannot accurately rotate the distance of each turn during detection, and errors often occur, and the detection accuracy is low. Moreover, manual adjustment is labor-intensive, prone to errors, and high labor costs, which greatly reduces the economic benefits of the enterprise.

The invention discloses a device and a method for detecting the length of needle valves, and belongs to the technical field of needle valves. The device comprises a stepping motor, wherein an output shaft of the stepping motor is provided with a first circular disc, the upper side of the first circular disc is provided with a second circular disc in parallel, the second circular disc is provided with four notches, the notches are internally provided with support plates, and V-shaped grooves are formed in the middle of the upper ends of the support plates; the support plates are provided with a first station, a second station, a third station and a fourth station, respectively; the support plate with the first station and the support plate with the third station are positioned on the same horizontal line. Compared with the prior art, the detection device and the detection method, which are disclosed by the invention, can realize the automatic detection of the length of the needle valves and can be used for automatically sorting the needle valves with qualified and unqualified lengths without manual operation, thereby improving the production efficiency, meeting the requirements of domestic and overseas production enterprises and greatly enhancing the economic benefit of the enterprises.
Description
technical field [0001] The invention belongs to the technical field of needle valves, and in particular relates to a detection device and a detection method for the length of a needle valve. Background technique [0002] There are two types of needle valves, one is used in the pipeline, mainly for throttling and decompression, and the other is used for maintenance (adding fluoride, refueling), a bit like a one-way valve, through the plug inside the fluoride hose connector Open. The needle valve is a slender and tapered needle, suitable for throttling in the low flow range. In addition, the needle valve is also used for maintenance. For example, there is a needle valve on the centrifuge of a company. When maintaining and debugging, it can be connected with a pressure gauge to debug and repair the unit. [0003] At present, when detecting needle valves, the number of turns of the needle valve is generally adjusted manually. This manual adjustment method cannot accurately rot...
