Abstract

The present invention provides an emergency valve maintenance control method, comprising: acquiring emergency valve profile information, and obtaining first size information and second size information according to the profile information; according to the first size information and the second size information Obtain third size information indicating the actual distance 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; compare the third size information with preset size information, And judge whether the third size information is qualified according to the comparison result, wherein, the preset size information is the distance 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. Qualified distance; when the third size information is unqualified, information for prompting inspection is generated. The invention can effectively control the assembly quality of the emergency valve.

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. By analyzing the failure of the emergency valve, the emergency sensitivity and stability of the emergency valve account for a relatively high proportion of the emergency valve failure. The reason is that the dimension chain of each component is not effectively measured and controlled during maintenance, especially when the dimension 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, it will As a result, when emergency braking should be performed, emergency braking does not occur, that is, a fault with poor emergency sensitivity will occur, which will bring safety hazards.
