Abstract
A kind of valve flanges fire resistant seal structure for installing metallic O ring, including valve body and bonnet, it is bolted between valve body and bonnet, metal O-ring seals are sealed between valve body and bonnet, metal O-ring seals are set in hollow state, metal O-ring seals are made of austenitic stainless steel material, and any one in layer gold and silver layer is coated with metal O-ring seals.The utility model has the advantages that：Metal O-ring seals can be made to reduce the erosion being subject under high temperature and high pressure condition act on, the generation of leakage is reduced, the sealing property of valve is improved, improve the low leakage performance of valve, and metal O-ring seals are easy to dismounting, are hardly damaged, and reduce cost, can be reached from pressurized effect using from pressurized hole, sealing property is improved, while using metal wound gasket, realizing double containment function, practical application effect is good, beneficial to popularization.
Description
Technical field
The utility model is related to valve technology field, more particularly to a kind of valve flanges fire resisting for installing metallic O ring is close
Seal structure.
Background technology
At present, flange sealing structure in the routine in valve, as soon as generally there was only seal structures between valve body and bonnet,
It is to be formed to seal by compressed metal wound gasket, because metal wound gasket is directly contacted with medium, under the operating mode of HTHP,
It is long-term to be susceptible to leakage by erosion, also, metal wound gasket is easily damaged, it is necessary to more in valve reprocesses disassembly process
Change, increased cost.
Utility model content
The utility model will solve the problems, such as above-mentioned prior art, there is provided a kind of valve method of installation metallic O ring
Blue fire resistant seal structure, by increasing capacitance it is possible to increase sealing effectiveness, meets the demand of valve.
The utility model solves the technical scheme of its technical problem use：This valve flanges for installing metallic O ring are resistance to
Fiery sealing structure, including valve body and bonnet, are bolted between valve body and bonnet, and metal is sealed between valve body and bonnet
O-ring seals, metal O-ring seals are set in hollow state, and metal O-ring seals are made of austenitic stainless steel material,
Any one in layer gold and silver layer is coated with metal O-ring seals.
It is provided with metal O-ring seals from pressurized hole.
Metal wound gasket is additionally provided between valve body and bonnet.
The utility model has the advantages that：The valve flanges fire resistant seal knot for installing metallic O ring of the present utility model
Structure, rational in infrastructure, the metal O-ring seals being made of austenitic stainless steel material are sealed, and in the sealing of metal O shapes
Layer gold or silver layer are coated with circle, are made metal O-ring seals that the erosion being subject to is reduced under high temperature and high pressure condition and is acted on, reduce leakage
Generation, improve valve sealing property, improve valve low leakage performance, and metal O-ring seals be easy to dismounting, be difficult
Damage, reduce cost, can be reached from pressurized effect using from pressurized hole, sealing property is improved, while using metal
Wound gasket, realizes double containment function, and practical application effect is good, beneficial to popularization.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the structural representation of the utility model embodiment metal O-ring seals.
Description of reference numerals：Valve body 1, bonnet 2, bolt 3, metal O-ring seals 4, from pressurized hole 5, metal wound gasket 6.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Referring to the drawings：The valve flanges fire resistant seal structure of this installation metallic O ring in the present embodiment, including valve body
1 and bonnet 2, fixed by bolt 3 between valve body 1 and bonnet 2, metal O-ring seals 4 are sealed between valve body 1 and bonnet 2,
Metal O-ring seals 4 are set in hollow state, and metal O-ring seals 4 are made of austenitic stainless steel material, and metal O shapes are close
Any one in layer gold and silver layer is coated with seal 4.
It is provided with metal O-ring seals 4 from pressurized hole 5.
Metal wound gasket 6 is additionally provided between valve body 1 and bonnet 2.
Metal O-ring seals 4 are made of austenitic stainless steel material, and layer gold and silver layer are coated with metal O-ring seals 4
In any one, the metal O-ring seals 4 being made of this material and coating, heat resisting and pressure resisting performance is good, in HTHP
The erosion that is subject to being reduced under operating mode to act on, being the aperture that is opened on metal O-ring seals 4 from pressurized hole 5, quantity can be
Multiple, valve pocket pressure enters into the inner chamber of metal O-ring seals 4 by from pressurized hole 5 when effect is work, reaches metal O shapes close
Seal is from pressurized effect, and operating pressure is higher, and sealing effectiveness is better, improves sealing property, is realized using metal wound gasket 6 double
Sealing effectiveness, increases sealing property.
The characteristics of the utility model embodiment is：The metal O-ring seals 4 being made of austenitic stainless steel material are carried out
Sealing, and layer gold or silver layer are coated with metal O-ring seals 4, metal O-ring seals 4 is subtracted under high temperature and high pressure condition
Few erosion being subject to is acted on, and reduces the generation of leakage, improves the sealing property of valve, improves the low leakage performance of valve, and
Metal O-ring seals 4 are easy to dismounting, are hardly damaged, and reduce cost, can be reached from pressurized effect using from pressurized hole 5, carry
High sealing performance, while using metal wound gasket 6, realizing double containment function, practical application effect is good, beneficial to popularization.
Although the utility model is shown and described by reference to preferred embodiment, this specialty is common
Technical staff is it is to be appreciated that in the range of claims, can make the various change in form and details.
