Abstract
A kind of valve double-layer movable sealing configuration, comprises valve body, valve rod, gland, bolt, it is characterized in that: in the Seal cage that valve body and valve rod are formed, adopt double-layer seal filler, be provided with transition layer between double-layer seal filler.Valve double-layer movable sealing configuration of the present utility model, when sealing configuration changes little, only increases one deck sealing, just greatly can improve the sealability of valve.Except possessing skills simple, cheap, nontoxic, non-environmental-pollution, housekeeping operation easily except advantage, cost is low.
Description
Technical field
The design relates to a kind of valve double-layer movable sealing configuration, belongs to valve technology field.
Background technique
Valve movable sealing structure technology is simple, cheap, nontoxic, non-environmental-pollution, housekeeping operation convenient, but the sealing configuration of one deck can not meet seal request sometimes, and needing increases sealing layer, enhanced leaktightness performance.
Summary of the invention
According to above-mentioned requirements, the object of the design is to provide a kind of valve double-layer movable sealing configuration, while maintenance valve movable sealing structure advantage, increases valve seal performance.
For achieving the above object, the design is realized by following technological means:
A kind of valve double-layer movable sealing configuration, comprises valve body, valve rod, gland, bolt, it is characterized in that: in the Seal cage that valve body and valve rod are formed, adopt double-layer seal filler, be provided with transition layer between double-layer seal filler.
Further:
Described a kind of valve double-layer movable sealing configuration, is characterized in that: described double-layer seal filler is teflon.
Described a kind of valve double-layer movable sealing configuration, is characterized in that: described polytetrafluoroethylene packing is V-arrangement.
Described a kind of valve double-layer movable sealing configuration, is characterized in that: described gland and valve body are bolted.
Described a kind of valve double-layer movable sealing configuration, is characterized in that: described bolt is four.
Described a kind of valve double-layer movable sealing configuration, is characterized in that: described valve double-layer movable sealing configuration is applicable to fluid occasion.
The invention has the beneficial effects as follows: valve double-layer movable sealing configuration of the present invention, when sealing configuration changes little, only increase one deck sealing, just greatly can improve the sealability of valve.Except possessing skills simple, cheap, nontoxic, non-environmental-pollution, housekeeping operation easily except advantage, cost is low.
Accompanying drawing explanation
Fig. 1 is the design's structural representation.
Embodiment
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, a kind of valve double-layer movable sealing configuration, comprises valve body 1, valve rod 4, gland 2, bolt 6, it is characterized in that: in the Seal cage that valve body 1 and valve rod 4 are formed, adopt double-layer seal filler 5, be provided with transition layer 7 between double-layer seal filler.
The filler of transition layer can with valve rod, valve body with larger Spielpassung, to reduce frictional force each other.
