Abstract
The invention discloses a valve graphite sealing structure. The valve graphite sealing structure comprises a gland, an upper cover and a valve rod, and is characterized in that the upper cover and the valve rod are sealed by adopting a graphite filler; synthesized fillers are arranged above and below the graphite filler. The valve graphite sealing structure disclosed by the invention has the characteristics of corrosion resistance, low temperature resistance, high temperature resistance, high self-lubricating performance, high elasticity, high sealing performance and wide application.
Description
Technical field
The design relates to a kind of valve graphite grazing structure, belongs to valve technology field.
Background technique
Valve seal technology is one of key technology of valve, and in some corrosion and high temperature, high pressure occasion, usual sealing material often can not meet the demands, and at this moment, just needs the sealing material adopting some special.
Summary of the invention
According to above-mentioned requirements, the object of the design is to provide a kind of valve graphite grazing structure, corrosion-resistant, low temperature resistant, high temperature resistant, and self-lubricating property is good, elasticity large, has the advantages that good sealability is wide with adapting to occasion.
For achieving the above object, the design is realized by following technological means:
A kind of valve graphite grazing structure, comprises gland, upper cover, valve rod, it is characterized in that: adopt graphite packing to seal between described upper cover and valve rod, graphite packing has synthetic filling.
Further:
Described a kind of valve graphite grazing structure, is characterized in that: described synthetic filling is material with carbon element.
Described a kind of valve graphite grazing structure, is characterized in that: the height of described graphite packing with provided thereon under the height of synthetic filling identical.
Described a kind of valve graphite grazing structure, is characterized in that: be bolted between described gland and upper cover.
Described a kind of valve graphite grazing structure, is characterized in that: described gland is connected by four bolts with between upper cover.
Described a kind of valve graphite grazing structure, is characterized in that: described a kind of valve graphite grazing structure is applicable to corrosion-resistant occasion.
The invention has the beneficial effects as follows: the valve graphite grazing structure of the design, corrosion-resistant, low temperature resistant, high temperature resistant, and self-lubricating property is good, elasticity large, has the advantages that good sealability is wide with adapting to occasion.
Accompanying drawing explanation
Fig. 1 is the design's structural representation.
Embodiment
Graphite grazing structure, corrosion-resistant, low temperature resistant, high temperature resistant, and self-lubricating property is good, elasticity large, has the advantages that good sealability is wide with adapting to occasion.But because graphite packing intensity is lower, need with other filler hybrid precasts.
