Abstract
The utility model provides a kind of flat gasket structure of high-pressure bottle, including male flange and flat cover, the seal end face of the male flange is provided with stainless steel connection ring, stainless steel connection ring end face is connected with flat shim, flat shim is pressed on the end face of stainless steel connection ring by the flat cover, it is provided with circular groove on one side end face of the flat shim, there are planar annulars for the edge of circular groove and the edge of flat shim, the spherical groove of recess, the edge of spherical groove and the coincident of flat shim are provided on another side end face of the flat shim.Flat shim both ends of the surface setting in the flat gasket structure is fluted, increases the deflection of flat shim, improves leakproofness.
Description
Technical field
The utility model is related to a kind of high-pressure bottles, particularly relate to a kind of flat gasket structure of high-pressure bottle.
Background technology
The sealing structure of high-pressure bottle is an important component of entire high-pressure bottle, and cost accounts for about totle drilling cost
25% or so, can high-pressure bottle continuously work normally, and be heavily dependent on the degree of perfection of sealing structure, at present high pressure
There are commonly the sealing structures such as plain cushion, bipyramid, Wood, Caza, the gaskets of wherein flat gasket to be mainly for container sealing structure
Using metal plain cushion, it belongs to forced sealing, is acted on by the preload of stud, so that gasket is generated certain plastic deformation, fill out
The place that is uneven of full seal face, to reach sealing purpose.It is not high and straight that this sealing is generally only suitable for temperature, pressure
The smaller high-pressure bottle of diameter, but for temperature, pressure higher (or fluctuation larger) and be relatively large in diameter and special media (height danger
Evil, the media such as price is valuable) high-pressure bottle when, sealing performance is just poor, reduces the reliability of equipment safety operation.
Utility model content
In order to solve the above problem present in reality, the utility model provides a kind of flat gasket knot of high-pressure bottle
Structure.
The utility model is achieved through the following technical solutions, a kind of flat gasket structure of high-pressure bottle, including convex
Lot or luck by which people are brought together is blue and flat cover, the seal end face of the male flange are provided with stainless steel connection ring, stainless steel connection ring end face
It is connected with flat shim, flat shim is pressed on the end face of stainless steel connection ring by the flat cover, a side end face of the flat shim
On be provided with circular groove, the edge of circular groove and the edge of flat shim there are planar annular, the other sides of the flat shim
The spherical groove of recess, the edge of spherical groove and the coincident of flat shim are provided on end face.
Compared to the prior art, advantage is a kind of flat gasket structure of high-pressure bottle of the utility model：
1, the flat gasket structure simple structure and reliable sealing is suitble to temperature, pressure higher (or fluctuation is larger) and diameter
The Seals for High Pressure Containers of larger and special media (media such as height endangers, price is valuable), improves equipment safety operation
Reliability.
2, the flat shim both ends of the surface setting in the flat gasket structure is fluted, increases the deflection of flat shim, improves
Leakproofness.
Description of the drawings
Fig. 1 is the structural schematic diagram of the flat gasket structure of the utility model high-pressure bottle.
Fig. 2 is enlarged view at F in Fig. 1.
Fig. 3 is the enlarged view of part 2 in Fig. 1.
In figure, 1. male flanges, 2. flat shims, 3. flat covers, 4. stainless steel connection rings, 5. plain cushions compression point, 6. is round recessed
Slot, 7. spherical grooves.
Specific implementation mode
The flat gasket structure of the utility model high-pressure bottle is further retouched with specific embodiment below in conjunction with the accompanying drawings
It states.
Fig. 1 be the utility model high-pressure bottle flat gasket structure structural schematic diagram, Fig. 2 be in Fig. 1 F place amplification
View, Fig. 3 are the enlarged views of part 2 in Fig. 1.In figure, the flat gasket structure of the high-pressure bottle includes male flange 1 and flat cover
3, the seal end face of the male flange 1 is provided with stainless steel connection ring 4, and stainless steel connection ring 4 is risen with stainless steel built-up welding
The annular ring come, end face processing is smooth, and the end face of stainless steel connection ring 4 is connected with flat shim 2, and flat shim 2 connects with stainless steel
The welding of ring 4 is connect, flat shim 2 is pressed on the end face of stainless steel connection ring by flat cover 3, and circle is provided on a side end face of flat shim 2
Connected in star 6, the edge of circular groove 6 and the edge of flat shim are set on another side end face of the flat shim 2 there are planar annular
It is equipped with the spherical groove 7 of recess, the edge of spherical groove and the coincident of flat shim.Utilize the special fastening device of high-pressure bottle
Stud, nut and flat shim are installed, flat cover 3 is pressed on plain cushion and compresses at point 5 at this time, then carries out pressure test, tests
Stud is removed after qualification, then flat shim and male flange sealing welding, postwelding welding point is after surface nondestructive detection is qualified, most
Stud, nut are installed with fastening device again afterwards.
Flat shim both ends of the surface setting in the flat gasket structure is fluted, increases the deflection of flat shim, improves
Leakproofness.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these changes and improvements all fall within the protetion scope of the claimed invention.The requires of the utility model
Protection domain is defined by the appending claims and its equivalent thereof.
