The model utility content
For addressing the above problem, the utility model is intended to propose that component are few, a kind of novel butterfly valve of compact structure, stable performance.
The technical scheme in the invention for solving the above technical problem is: a kind of novel butterfly valve, contain the rotation positioning device that is assembled into by handle, positioning rod, locating stud, spring, positioning plate, screw and protective cover, it is characterized in that: be provided with a ring-shaped step at flanged joint upper flange circle endoporus, respectively be provided with a semi-circular groove and a hole slot at the radially two ends of flange circle end face, two flanged joints connect and compose valve body, form valve pocket between two ring-shaped steps; Seal ring set be located in the valve pocket and with the ring-shaped step screens, corresponding groove of seal ring and hole slot position are provided with circular hole, valve block is placed in the seal ring, valve rod inserts valve block by groove and circular hole, valve stem end is in the hole slot; Valve rod passes positioning plate and is connected with handle.
Flanged joint of the present utility model is provided with pipe joint integrated with it, and pipe joint is the socket pipe joint; Pipe joint is active interface pipe joint, male connector or female union also, uses with the connection of the tubing that is applicable to various interface.
The beneficial effects of the utility model are: flanged joint is as valve body of the present utility model, seal ring and valve block constitute spool, by being connected with handle on the rotation positioning device, integral installation constitutes in the valve pocket between two ring-shaped steps on two flanged joints again, seal ring forms sealing with valve block and flanged joint simultaneously, constitute novel butterfly valve, structure is more compact, volume is littler, assemble more convenient fast, compare, directly be provided with pipe joint on the utility model two flanged joints with traditional flange butterfly, can directly take quick the connection by force, avoid the troublesome operation of using flange circle and flange body that tubing is installed with the pipe of various interface.
