Abstract

The invention discloses a butterfly valve which comprises a valve body, a valve rod and a butterfly plate. The valve rod is fixed into the valve body, the upper end of the valve rod is sleeved with an upper shaft sleeve, the lower end of the valve rod is sleeved with a lower shaft sleeve, the lower end of the upper shaft sleeve is fixedly provided with a support, a sealing surface is attached to the inner side of the valve body, a gasket is fixed to the inner side of the sealing surface, the butterfly plate is fixed to the outer side of the valve rod, the butterfly plate is movably connected with the valve body, a sealing gasket is fixed to the outer side of the butterfly plate, and the lower end of the lower shaft sleeve is fixedly provided with a lower gland. The butterfly valve has the advantages that a layer of the sealing surface is attached to the inner side of the valve body, the sealing surface and the sealing gasket on the butterfly plate are both made of polytetrafluoroethylene which is good in stability and not prone to being corroded and damaged, and meanwhile, a circle of aluminium oxide ceramic rings are additionally arranged between the sealing surface and the sealing gasket so that sealing performance can be improved.

Description

Butterfly valve
Technical field
The present invention relates to piping attachment technical field, relate in particular to butterfly valve.
Background technique
Butterfly valve is again Flap valve, is a kind of modulating valve simple in structure, also can be used for the mode of the switch control of low pressure pipeline medium simultaneously.Valve butterfly valve in work refers to that closure member is disk, rotate to reach a kind of valve of open and close around valve shaft, valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.On pipeline, main rising cut off and throttling action.Butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the object that opens and closes or regulate.Therefore, for butterfly valve, the sealing between valve body and butterfly plate is vital, the invention provides a kind of new technological scheme and addresses the above problem.
Summary of the invention
The invention provides the butterfly valve that a kind of tightness is good.
The technical solution used in the present invention: butterfly valve comprises valve body, valve rod and butterfly plate, valve inner is fixed with valve rod, valve rod upper end cover has Upper shaft sleeve, and valve rod lower end cover has Lower shaft sleeve, and Upper shaft sleeve lower end is fixed with support, valve body inner side is with sealing surface, sealing surface inner side is fixed with packing ring, and butterfly plate is fixed on the outside of valve rod, and butterfly plate is flexibly connected with valve body, butterfly plate outside is fixed with seal washer, and Lower shaft sleeve lower end is fixed with lower cover.
The material of above-mentioned sealing surface and seal washer is teflon, and above-mentioned packing ring is aluminium oxide ceramics ring.
Beneficial effect of the present invention: have a layer sealing surface in valve body inner side, seal washer on sealing face and butterfly plate is teflon, the good stability of this material, be difficult for being corroded and encroaching on, between sealing surface and seal washer, increase by a circle aluminium oxide ceramics ring, improve encapsulation simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1, valve body, 2, valve rod, 3, Upper shaft sleeve, 4, support, 5, sealing surface, 6, packing ring, 7, butterfly plate, 8, seal washer, 9, Lower shaft sleeve, 10, lower cover.
Embodiment
As shown in Figure 1, butterfly valve comprises valve body 1, valve rod 2 and butterfly plate 7, and valve body 1 inside is fixed with valve rod 2, and valve rod 2 upper end covers have Upper shaft sleeve 3, valve rod 2 lower end covers have Lower shaft sleeve 9, Upper shaft sleeve 3 lower ends are fixed with support 4, and valve body 1 inner side is with sealing surface 5, and sealing surface 5 inner sides are fixed with packing ring 6, butterfly plate 7 is fixed on the outside of valve rod 2, butterfly plate 7 is flexibly connected with valve body 1, and butterfly plate 7 outsides are fixed with seal washer 8, and Lower shaft sleeve 9 lower ends are fixed with lower cover 10.
The material of above-mentioned sealing surface 5 and seal washer 8 is teflon, and above-mentioned packing ring 6 is aluminium oxide ceramics ring.
Beneficial effect: have a layer sealing surface 5 in valve body 1 inner side, sealing face 5 is teflon with the seal washer 8 on butterfly plate 7, the good stability of this material, be difficult for being corroded and encroaching on, between sealing surface 5 and seal washer 8, increase by a circle aluminium oxide ceramics ring, improve encapsulation simultaneously.
