Embodiment

The utility model detailed structure, application principle, effect and effect with reference to accompanying drawing 1-2, are illustrated by following mode of execution.

As accompanying drawing 1-2, slurry valve of the present utility model, left valve barrel 1 are positioned at right valve barrel 12 belows, and both connect and compose Y shape valve body by the flange dock, and valve seat 3 is embedded at both joints; The import of valve is same center line with outlet, and this center line and valve rod center line are 45 ° of angles; The end of valve petal body 5 is connected with retainer ring 16, is embedded with flap 15 between both joints; Be embedded with wound gasket 3 14 between the vertical junction surface of flap 15 and valve petal body 5, be embedded with wound gasket 1 between valve seat 3 and left valve barrel 1 upper flange plate, be embedded with wound gasket 24 between valve seat 3 and right valve barrel 12 lower flanges; The top of valve petal body 5 is connected with valve rod 13.Between right valve barrel 12 upper flange plates and the Stem Mut 8 by about two root posts be connected, two root posts are symmetrically set in valve rod 13 center line both sides.Valve rod 13 tops are connected with Stem Mut 8, and handwheel 7 is connected with Stem Mut 8.Guide plate 6 and rear deflector 10 before being respectively equipped with about the middle part of valve rod 13.Right valve barrel 12 upper flange plate tops are provided with Gland 11, and valve rod 13 passes Gland 11 center holes.
