Technical field
The present invention relates to valve, a kind of novel butterfly valve of quick, reliable performance especially easy to assembly.
Background technique
The rotation positioning device that tradition butterfly valve (shown in Figure 1) is assembled into by handle 1, positioning rod 2, locating stud 3, spring 4, positioning plate 5, screw 6 and protective cover 7, and the valve that is assembled by valve body 9, valve block 10, valve rod 8, cushion rubber 11, flange connection cushion rubber 12, valve block connection cushion rubber 13 constitutes; As shown in Figure 2, by nut 16, bolt 17 adpting flange circle 14, the traditional flange butterfly of flange body 15 formations are installed, are used for pipeline 18 and connect in traditional butterfly valve both sides.Because the use of flange circle 14 cover flange bodies 15, make that the overall volume of flange butterfly is longer, must use the stay bolt adpting flange, assembling must be with the screw contraposition on valve body and two the flange circles, screw in each contraposition inserts stay bolt then, is connected with nut screwing clamping, and traditional flange butterfly is because assembly is many, Sealing is many, it is very inconvenient to assemble, and is unfavorable for the quick mounting of butterfly valve on pipeline connects.
Summary of the invention
For addressing the above problem, the present invention is intended to propose that component are few, a kind of novel butterfly valve of compact structure, stable performance.
The present invention addresses the above problem the technological scheme that is adopted: 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 invention 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 invention has the beneficial effects as follows: flanged joint is as valve body of the present invention, 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 present invention's two flanged joints with traditional flange butterfly, can directly be connected fast, avoid the troublesome operation of using flange circle and flange body that tubing is installed with the pipeline of various interface.
