Abstract
The utility model discloses a corrugated pipe fluorine lined valve, which comprises a valve body, a valve seat, a valve core, a valve rod and a lengthened valve cover, wherein the top end of the lengthened valve cover is provided with a stuffing box for sealing. The corrugated pipe fluorine lined valve is characterized in that a corrugated pipe is arranged in an inner cavity of the lengthened valve cover for sealing, the upper end of the corrugated pipe is connected with the valve rod, the lower end of the corrugated pipe is connected with a guide disc, the guide disc is fixedly arranged on the connecting end surface of the valve cover and the valve body, the valve rod movably penetrates through the middle of the guide disc, an inner hole of the corrugated pipe and the middle of a stuffing box arranged at the top end of the valve cover, and fluorine rubber is respectively lined on the surfaces of the inner cavity of the valve body, the valve seat, the valve core and the valve rod. The corrugated pipe fluorine lined valve is used in high-corrosion media conveying occasions and has the advantage of long service life.
Description
Technical field
The utility model relates to a kind of valve that high aggressive medium is carried occasion that is exclusively used in.
Background technique
At present, in the occasion that high aggressive medium is carried, valve is owing to influenced by corrosion, often working life shorter, though taked a lot of measures, effect is not ideal.
Summary of the invention
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of to carry occasion, the bellows fluorine-lining valve door with long service life advantage for high aggressive medium.
The utility model is implemented by the following technical programs:
Bellows fluorine-lining valve door, comprise valve body, valve seat, spool, valve rod and lengthening valve gap, the top that lengthens valve gap is provided with packing box seal, it is characterized in that: the inner chamber that lengthens valve gap is provided with sylphon seal, the upper end of bellows is connected with valve rod, the lower end is connected with positioning disk, positioning disk is fixed on the end face that is connected of valve gap and valve body, described valve rod in the middle of positioning disk, bellows endoporus and valve gap apex filler letter intermediate active pass, the surface of body cavity, valve seat, spool and valve rod all is lined with fluorine rubber.Fluorine rubber is the perfluoroethylene-propylene material, adopts mold pressing or method for embedding to place the surface of body cavity, valve seat, spool and valve rod.Bellows adopts the teflon material.The surface of internal cavity that lengthens valve gap also is lined with fluorine rubber.
After adopting technique scheme, at first, the valve internals that contacts with high aggressive medium all are lined with the fluorine rubber protection, so improved the corrosion resistance of valve greatly, raising valve working life; Secondly a bit, sylphon seal and packing box seal constitute the two seals of fluorine-lining valve door, make valve seal good, can be used for chemical industry corrosion occasion, have increased the using scope of valve.Also have, fluorine rubber is the perfluoroethylene-propylene material, not only have the similar characteristic of teflon but also have the thermoplastic good processing properties, the temperature resistant range of perfluoroethylene-propylene material-200 ℃～270 ℃ has high low temperature using scope widely, excellent chemical stability, high electrical insulating property, outstanding surface not viscosity, good lubricity, resistance to weathering energy, incombustibility and self-extinguish ability.Bellows adopts the teflon material, has good anti-corrosion, goes for various corrosive bad working environments.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Embodiment
