Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valves, in particular to a new spring device used on valves. Background Art
[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. They are control components in fluid conveying systems and have functions such as cutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. They can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.
[0003] The impact force generated by the fluid flowing in the valve lifts the valve core, allowing the fluid to flow normally. The internal spring provides closing force or opening force. The spring will become elastic or even break during long-term use. Existing valves are generally maintained by loosening the bolts between the valve cover and the valve body, removing the valve cover and then installing it again, which is very cumbersome. In addition, the bolts will rust after long-term use, which increases the difficulty of maintenance. Therefore, we designed a new spring device for valves. Utility Model Content
