Abstract
The utility model relates to a stop valve, which comprises a valve body, a valve cap, a valve clack, and a valve rod. The utility model is characterized in that: the valve rod in the valve cover is connected with the valve clack, the valve clack and the valve body form a sealed combination, a layer of polytetrafluoroethylene is lined in the valve body, a layer of polytetrafluoroethylene is lined outside the valve clack, a layer of polytetrafluoroethylene is lined in the inner wall of the valve body which is connected with the valve cover, the polytetrafluoroethylene layer on the upper end of the valve clack is sealed with the stuffing box around which is also made of polytetrafluoroethylene. The utility model overcomes the defects of seal imprecision, bad corrosion resistance performance of the conventional stop valve, and has the advantages of simple structure, strong corrosion resistance performance and good sealing effect.
Description
The utility model relates to a kind of stop valve.
Stop valve is a kind of the valve for the usefulness of the medium operation on standard-sized sheet, all kinds of pipelines of complete shut-down or the equipment.Traditional stop valve, its valve body, valve gap and flap are all made by cast iron, cast steel or stainless steel material, and poor corrosion resistance is poorly sealed close, is not fit to be with corrosive medium to use.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thereby a kind of simple in structure, sealing is tight, decay resistance is strong stop valve is provided.
The utility model comprises valve body, valve gap, flap and valve rod, and the valve rod in the valve gap is connected with flap, and flap and valve body form and be sealed and matched valve body inner liner polytetrafluoroethylene layer, flap outer lining polytetrafluoroethylene floor.
The inwall inner liner polytetrafluoroethylene layer that valve gap links to each other with valve body, the outer lining polytetrafluoroethylene floor of flap upper end and the packing box seal around it, stuffing box adopts polytetrafluoroethylmaterial material.
Below in conjunction with accompanying drawing and implementation detailed content of the present utility model.
Accompanying drawing is a structural representation of the present utility model.
As scheme institute, the utility model comprises valve body 1, valve gap 2, flap 3 and valve rod 4, valve rod 1 in the valve gap 2 is connected with flap 3, flap 3 forms with valve body 1 and is sealed and matched, valve body 1 inner liner polytetrafluoroethylene layer 5, flap 3 outer lining polytetrafluoroethylene floors 6, the inwall inner liner polytetrafluoroethylene layer 7 that valve gap 3 links to each other with valve body 1, the thickness of polytetrafluoroethylene floor is the 3-4 millimeter, the outer lining polytetrafluoroethylene floor 6 of flap 3 upper ends and its stuffing box 8 sealings all around, stuffing box 8 is same to adopt polytetrafluoroethylmaterial materials, and have an optimal seal effect be the elasticity polytetrafluoroethylmaterial material.Like this, just form at the inner chamber of valve body totally-enclosed, full cylinder-packing structure.
The utility model is by above-mentioned specific design, has simple in structurely, and sealing is tight, and is anti-The advantage that corrosive nature is strong is particularly suitable for being with corrosive medium operation to use.
