Description

TECHNICAL FIELD

[0001] The utility model belongs to valve detection equipment technical field especially, relate to a butterfly valve handle reset spring piece fatigue degree's detection device. BACKGROUND

[0002] Butterfly valve is a kind of key valve widely used in fluid control system, and it realizes the adjustment and cut-off of medium flow through the rotation of butterfly plate. The performance of butterfly valve directly influences the running efficiency and reliability of system, and the service life of butterfly valve handle as the main component of operation control is crucial in practical application. High-quality butterfly valve handle should have high strength, corrosion resistance and good operation convenience, and can maintain stable performance in high-frequency opening and closing operation. If the service life of handle is insufficient, it can lead to operation failure, frequent maintenance, even affect the sealing performance and service life of butterfly valve as a whole, thereby adversely affecting the safety and economy of system. Therefore, the service life of butterfly valve and its handle is not only an important index for evaluating product quality, but also a key factor for ensuring long-term stable operation under complex working conditions.

[0003] At present, there are the following problems and deficiencies in the detection process of butterfly valve handle service life: first, the traditional detection method highly depends on manpower, and the detection is completed by repeatedly lifting the handle manually and relying on the elastic recovery position of reset spring piece. This operation is not only tedious but also consumes a lot of time and energy, resulting in extremely low overall detection efficiency, especially when multiple handles need to be detected, it is difficult to meet the actual work requirements. Secondly, due to the subjectivity and human error of manual operation, the detection accuracy and consistency are difficult to guarantee, which affects the reliability of detection results. In addition, although the existing automatic detection device can realize the detection of butterfly valve handle service life to a certain extent, it can only operate on a single test piece, and cannot detect multiple handles at the same time, so the application range is limited and the flexibility is insufficient. At the same time, the automation degree of these devices is not perfect, and the detection effect needs to be further improved. The complexity and maintenance cost of equipment are high, and the performance-price ratio between use cost and performance is low, the economic benefit is poor, and it is difficult to be widely used in actual production and detection. In summary, the butterfly valve handle service life detection has great problems in efficiency, accuracy, applicability and economy, and needs to be improved through innovative design and technical upgrading.
