Abstract
The present invention relates to a sealing device and sealing technology for the end surface of an observation window of an ultrahigh pressure container. The sealing device comprises a sealing seat, a piece of glass for an observation window, a sleeve barrel, a spring and a spring cushion block, wherein the sleeve barrel and the sealing seat are connected and fixed by screw threads, the end surface of the sealing seat is attached to the contact surface of the glass for an observation window, and the other surface of the glass for an observation window is attached to the spring cushion block supported by a plurality of spring supports arranged in the sleeve barrel. The technology comprises: the contact surface of the glass for an observation window and the end surface of the sealing seat are ground; after the surfaces are attached to each other, general glue water is spread along the periphery of the contact surface of the glass for an observation window to bond the two surfaces, and sealing pressure is applied to the sealing end surface 20 minutes later.
Description
What the present invention relates to is a kind of end face seal technology and device thereof, and especially a kind of ultrahigh pressure vessel viewing window end face seal technology and device thereof belong to sealing class field.
End face seal technology and device thereof are researched and developed on packing matcrial mostly in the prior art, in order to improve sealability, packing is selected Paranite for use, also useful soft metal gold is made gasket seal, though can satisfy this certain sealability, but still can't be used for ultrahigh pressure vessel.Utilize glass welded seal technology to be used for the sealing of ultrahigh pressure vessel in addition, be about to glass material through heating, clinkering is on the sealing seat end face, reach sealing effect with this, but because the glass welding requirements is very high, the cost height is wasted time and energy, because of welding produces distortion, directly influence viewing window transparent effect or sealing effect again.
The objective of the invention is to overcome the deficiencies in the prior art and defective, a kind of new ultrahigh pressure vessel viewing window end face seal technology and device thereof are provided, solved the effective seal problem of ultrahigh pressure vessel viewing window.
Technological scheme of the present invention is achieved in that and the present invention includes ultrahigh pressure vessel viewing window face seals part and ultrahigh pressure viewing window end face seal process portion.Ultrahigh pressure vessel viewing window face seals comprises sealing seat, viewing glass, sleeve, spring, spring cushion block, sleeve and sealing seat are fixing by being threaded, in sleeve, sealing seat end face and viewing glass surface of contact are fitted, both are bonding on viewing glass surface of contact periphery edge by glue, the another side of viewing glass and spring cushion block are fitted, and the spring cushion block is by several spring-loadeds that are located in the sleeve; Ultrahigh pressure viewing window end face seal technology, at first must grind viewing glass surface of contact and sealing seat end face, make the roughness of these two faces reach 0.80～0.05 μ m (being equivalent to former degree of finish 10- 14), after fitting, two faces can form molecule thickness inter-stage crack, the escape of liquid resistance of flowing medium greatly increases, continue to use common viscosity glue in viewing glass surface of contact periphery then, both are bonding, keep about 20 minutes, can form the initial sealing between seal face like this, to between seal face, apply a sealing load then, this pressure can form and all have minimum molecule thickness inter-stage crack between seal face reliably under any pressure, thereby can eliminate the influence that makes seal failure because of pressure surge, according to non-supported end face seal principle, sealing medium pressure will be lower than the footprint pressure between seal face all the time, guarantee to contact gap minimum between end face with this.To applying an initial sealing pressure between seal face, can realize by spring is set.
The present invention has broken traditional end face seal technology, particularly create new sealing technology and the device thereof of a cover when ultrahigh pressure vessel is provided with viewing window, structure and technology are greatly simplified than conventional art, and fabricating cost greatly reduces, sealing is reliable, and sealing load can reach 500Mpa.
Further specify below with reference to accompanying drawing:
Fig. 1 ultrahigh pressure vessel viewing window structural representation
As shown in Figure 1, ultrahigh pressure vessel viewing window face seals of the present invention, comprise sealing seat 1, viewing glass 2, sleeve 3, spring 4, spring cushion block 5, sleeve 3 and sealing seat 1 are fixing by being threaded, in sleeve 3, sealing seat 1 end face and viewing glass 2 surface of contact are fitted, and are by glue that both are bonding on viewing glass 2 surface of contact peripheries edge, the another side of viewing glass 2 and spring cushion block 5 are fitted, and spring cushion block 5 is by several spring 4 supportings that are located in the sleeve 3.
Ultrahigh pressure vessel viewing window end face seal technology is to implement like this, viewing glass 2 surface of contact and sealing seat 1 end face are ground, make the roughness of these two abradant surfaces reach 0.80～0.05 μ m (being equivalent to former degree of finish 10- 14), after two faces are fitted, it is bonding with both to continue to use common glue in viewing glass 2 surface of contact peripheries, bonding back about 20 minutes, apply a sealing load to seal face, this sealing load can realize that sealing pressure can form and all have minimum molecule thickness inter-stage crack between seal face reliably under any pressure by the spring 4 that is arranged in the sleeve 3.
