Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below in conjunction with specific embodiment.
See Fig. 1-4, a kind of full lining Ceramic butterfly gate, mainly comprise valve body 1, valve plate 5 and upper and lower valve rod (9,2), upper and lower axis hole is provided with in valve body, the aperture of upper and lower axis hole is respectively provided with ceramic valve seat 4, and upper valve rod is arranged in upper shaft hole by axle sleeve (10,8), and lower valve rod is arranged in the lower shaft hole of valve body by axle sleeve 3, the valve plate connecting end of upper and lower valve rod is provided with Ceramic shaft sleeve 6, and valve plate 5 is lining structure pottery valve plate.Full lining Ceramic butterfly gate of the present utility model, the runner that all media pass through is all by structural ceramics phase contrast.The utility model can meet high wearing and tearing, the Environmental Conditions of deep-etching, and (coal dust sprays to be specially adapted to steel mill, desulfuration of foundry iron), the flue gas desulphurization system slag removing system of power plant and combustion system, the salt solution of alkali factory, distillation process, the paper pulp control system in paper mill, the washing systems in colliery etc.
See Fig. 2, lining structure pottery valve plate is patty, and intermediate portion is concave-concave hemisphere.Valve plate is the eccentric valve plate playing cam effect effect, and the longitudinal center line of valve plate departs from the longitudinal center line 1.5mm of valve body.The cross central line of valve plate departs from valve body tube Lu Zhizheng line 3.2mm.With the crossing point of these two line of eccentricity for axle center, in valve opening stroke, play a cam effect effect.This technological scheme makes to there is not friction between sealing surface of valve plate and sealing surface of seat, solves the leakage problem because of abrasion.
When this valve latus rectum (DN) is less than or equal to 200mm, this valve plate is overall structure ceramic fitting; When latus rectum is greater than 200, this valve plate is Cast Steel externally-packed structure pottery 11, increases the intensity of structural ceramics valve plate.Whole valve plate is patty.Intermediate portion is concave-concave hemisphere.Rotation valve rod, utilizes eccentric cam effect, and valve plate and valve seat can not produce friction.As long as but valve plate and valve seat can reach sealing effect at a touch.
Ceramic valve seat 4 is provided with the arc surface sealed, described valve plate is provided with the fitting surface corresponding with described arc surface, between described valve plate and ceramic valve seat 4, circular arc seals.Can see from Fig. 3 " sealing surface partial enlarged drawing ", the sealing of butterfly plate and valve seat is circular arc.
The utility model is unidirectional back seat automatic-sealed, and as shown in Figure 1, arrow is depicted as media flow postive direction, and medium enters on the right of valve body.After valve closing, medium pushes valve plate to valve seat, and pressure is larger, and it is better to seal.As client's operating mode needs, medium also can enter from the left side, is negative direction flowing, is called two-way flow, does not affect usability of the present utility model.
The lower end of upper valve rod and the upper end side of the being tenon shape of lower valve rod, valve seat is provided with square hole, and the lower end of upper valve rod and the upper end of lower valve rod are connected in the square hole of valve seat.This join strength that can increase valve rod and valve plate without pin connection.In the upper end of upper valve rod, be provided with keyway, user can load onto drive unit according to the needs of operating mode on butterfly valve upper flange.As handwheel, worm and gear, the device such as pneumatic, electronic.
