Abstract

The invention provides an emergency valve maintenance control method which comprises the following steps: acquiring contour information of an emergency valve, and acquiring first size information andsecond size information according to the contour information; according to the first size information and the second size information, obtaining third size information indicating the actual distance between the end, close to the air release valve, of the emergency piston rod and the end, close to the air release valve, of the ejector rod; comparing the third size information with preset size information, judging whether the third size information is qualified according to the comparison result, and the preset size information is the qualified distance between the end, close to the air releasevalve, of the emergency piston rod and the end, close to the air release valve, of the ejector rod; and when the third size information is unqualified, generating information for prompting inspection.The assembling quality of the emergency valve can be effectively controlled.

Description

technical field [0001] The present invention relates to the technical field of emergency valves, in particular to an emergency valve maintenance control method. Background technique [0002] In the prior art, the emergency valve is an important component of the air control valve. Through the analysis of the failure of the emergency valve, the emergency sensitivity and stability of the emergency valve account for a relatively high proportion of the failure of the emergency valve. The reason is that the size chain of each component is not effectively measured and controlled during maintenance, especially when the size between the end of the emergency piston rod close to the air release valve and the end of the ejector rod close to the air release valve is unqualified, the As a result, when emergency braking should be performed, if emergency braking does not occur, a failure of poor emergency sensitivity will occur, thereby bringing potential safety hazards.
