The invention discloses an integrated butterfly valve check valve articulation structure, in particular to the field of butterfly valve check valves. The outer surface of the conduit is located on one side of the retaining ring, and a mounting plate is fixedly installed, one side of the outer ring is provided with a butt pipe, one end of the butt pipe is fixedly installed with a snap ring, and the inside of the outer ring is provided with an inner pipe. ring. In the present invention, by setting the outer ring, the inner ring, the clamping post and the first clamping groove, when connecting with the butt pipe, one can insert the clamping ring at one end of the butt pipe into the inner ring, and then rotate the outer ring to make the inner wall of the outer ring The second magnet of the clasp corresponds to the second magnet at one end of the limit rod, so that one end of the limit rod is inserted into the limit groove of the clasp, so as to fix the clasp, and the whole process of installation and disassembly does not require the use of other aids The tool is convenient for people to install and disassemble the check valve articulated structure, which is more practical.
Description
technical field [0001] The present invention relates to the field of butterfly valve check valves, and more particularly, the present invention relates to an integrated butterfly valve check valve articulation structure. Background technique [0002] The valve is a control component in the fluid conveying system, with functions such as cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow pressure relief. The flow of various types of fluids such as various corrosive media, mud, oil, liquid metal and radioactive media. [0003] Patent Application Publication No. CN109163123A discloses an integrated butterfly valve check valve articulation structure. The steel belt is tightened by locking the handle, so that the limit block is tightly embedded in the limit groove, and the eccentric joint is clamped in the limit groove. On the valve body, the purpose of quick connection is realized, the flexibility of the connection between the va...
