Abstract
A kind of refrigeration valve packing seal structure, it belongs to the valve field of refrigeration system.Including valve gap, valve rod, packing ring and V-type PTFE filler, described valve rod is arranged on valve gap, and through valve gap；Described packing ring, V-type PTFE filler are arranged on the joint portion of valve gap and valve rod, and V-type PTFE filler is positioned close to the position of valve gap, and packing ring is arranged far from the position of valve gap；Packing ring and V-type PTFE filler are in close contact.Inlay twice regular rubber ring on described packing ring, between twice regular rubber ring, oil storage tank is set.Inlay the antifouling ring of rolling on described packing ring, roll antifouling ring and be arranged on regular rubber ring top.This structure can meet cooling valve the requirement of 55 DEG C ~ 150 DEG C, frequently switches on, it is ensured that seals, makes poisonous and harmful medium not produce the phenomenon that leaks outside.
Description
Technical field
This utility model relates to a kind of refrigeration valve packing seal structure, and it belongs to the valve field of refrigeration system.
Background technology
Refrigeration valve is mostly installed at refrigeration system, is used as connect and block medium, and operating temperature reaches-55 DEG C ~ 150
DEG C, for poisonous and harmful medium, it is breakneck that medium leaks outside.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, this utility model provides a kind of refrigeration valve packing seal knot
Structure, uses the design of double containment filling-material structure.
This utility model solves its technical problem and be the technical scheme is that
A kind of refrigeration valve packing seal structure, including valve gap, valve rod, packing ring and V-type PTFE filler, described valve rod is pacified
It is contained on valve gap, and through valve gap；Described packing ring, V-type PTFE filler are arranged on the joint portion of valve gap and valve rod, V-type PTFE
Filler is positioned close to the position of valve gap, and packing ring is arranged far from the position of valve gap；Packing ring and V-type PTFE filler closely connect
Touch.Inlay twice regular rubber ring on described packing ring, between twice regular rubber ring, oil storage tank is set.On described packing ring
Inside inlay the antifouling ring of rolling, roll antifouling ring and be arranged on regular rubber ring top.
After using such scheme, compared with prior art have the advantages that packing ring inlays twice square in using
Shape rubber ring, twice regular rubber ring medium design oil storage tank, not only achieve sealing but also achieve rich lubrication, and twice rectangle
Rubber ring also functions to the effect sealed to oil storage tank；Roll antifouling ring on first rectangular loop top, prevent foreign matter from entering
Impact seals；Set up V-arrangement PTFE filler in the bottom of packing ring, play the effect of dual-seal, frequently switch on, it is ensured that seal.
Accompanying drawing explanation
Fig. 1 is seal ring structure schematic diagram；
Fig. 2 is double sealing structure schematic diagram；
In figure: 1, valve gap, 2, valve rod, 3, packing ring, 4, V-type PTFE filler, 5, regular rubber ring, 6, roll antifouling ring,
7, oil storage tank.
Detailed description of the invention
For understanding refrigeration valve packing seal structure in depth, it is described as follows in conjunction with Fig. 1, Fig. 2:
A kind of refrigeration valve packing seal structure, including valve gap 1, valve rod 2, packing ring 3 and V-type PTFE filler 4, described valve
Bar 2 is arranged on valve gap 1, and through valve gap 1；Described packing ring 3, V-type PTFE filler 4 are arranged on valve gap 1 and the combination of valve rod 2
Portion, V-type PTFE filler 4 is positioned close to the position of valve gap 1, and packing ring 3 is arranged far from the position of valve gap 1；Packing ring 3 and V
Type PTFE filler 4 is in close contact.Inlay twice regular rubber ring 5 on described packing ring 3, arrange between twice regular rubber ring
Oil storage tank 7.Inlay the antifouling ring 6 of rolling on described packing ring 3, roll antifouling ring 6 and be arranged on regular rubber ring 5 top.
