Detailed Description
The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.
A novel pipe orifice blind plate-ball valve interchanging device shell mounting structure comprises a lower barrel body 1 and an upper barrel body 2, wherein the section of the lower barrel body is polygonal, a pipe orifice mounting groove 5 is formed in the lower barrel body, a rotating shaft seat mounting groove 6 is formed in one side of the pipe orifice mounting groove of the lower barrel body, a flange-free straight edge 10 is reserved on the upper edge of the lower barrel body, flange edges 9 are formed on other edges of the upper edge of the lower barrel body, the section of the upper barrel body is polygonal corresponding to the lower barrel body, and a flange edge corresponding to the upper barrel body is formed on the bottom edge of the upper barrel body; the lower surface of the pipe orifice mounting groove of the lower cylinder body is provided with a locking ring 4.
The lower surface of the pipe orifice mounting groove of the lower cylinder body is provided with symmetrical locking rings, one of the butt joints of the two locking rings is provided with a bolt mounting groove 11, the other one is provided with a bolt mounting hole 12, and the two locking rings are locked on the pipe orifice 3 through a bolt in the bolt mounting groove. And the side wall of the lower cylinder body is provided with a puller pin 7.
