Abstract
The utility model discloses a high pressure steam sealing device, include: high pressure steam tube head, the one of which facing (operation) has the countersunk head screw hole, the flange end cap for the assembly realizes sealedly in the countersunk head screw hole of high -pressure steam pipe head end portion, and its head outer wall processing has the external screw thread, composite pads piece, its cover are established between flange terminal surface and countersunk head screw hole end face of bench, it is formed along the radial cover of folding by a plurality of stainless steel ring and graphite annulus. The utility model discloses the beneficial effect who has: realize the sealed of tube head through flange end cap and composite pads piece to the high -pressure steam pressure up to 1.6 MPas can be born, the poor defect of sealing performance among the prior art has effectively been solved. In addition, offer the long -pending bits groove of annular on the flange terminal surface, thereby the graphite bits that can make the graphite annulus produce focus on all and form the second in the long -pending bits groove of annular and say sealedly, further put forward the high leakproofness ability.
Description
Technical field
The utility model belongs to foaming technical field and in particular to a kind of high steam sealing device.
Background technology
Felt or foam class product need when producing to make shaping again by after the heating of mould steam, and at this moment mould will
Bear certain steam pressure, the phenomenon but plug of pipeline easily leaks air, thus cause the waste of high steam, even
Produce other adverse consequences.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of high steam sealing device, energy
Enough improve tube head sealing property.
For solving prior art problem, the utility model discloses a kind of high steam sealing device, comprising:
High steam tube head, one end is machined with countersunk head screwed hole；
Blind flange, realizes sealing, its head outer wall for being assemblied in the countersunk head screwed hole of high-pressure steam pipe cephalic par
It is machined with external screw thread；
Composition spacer, it is set between end face of flange and countersunk head screwed hole step end face；Its by some stainless steel rings and
Graphite annulus is radially nestable to be formed.
Preferably, the end face of flange of blind flange offers some annular scrap slots.
Preferably, the quantity of annular scrap slot is two.
Preferably, the cross sectional shape of annular scrap slot is semicircle or triangle.
Preferably, the periphery of Composition spacer and inner headed face are stainless steel ring.
Preferably, the outer end of blind flange is machined with inner hexagonal hole.
The utility model has the advantages that the sealing realizing tube head by blind flange and Composition spacer, and can hold
By up to 1.6 MPas of high-pressure steam pressure, efficiently solve the defect of poor sealing performance in prior art.Additionally, in flange
Annular scrap slot being opened up on end face, the graphite bits that graphite annulus produces being made all to focus in annular scrap slot thus forming second
Road seals, and improves sealing property further.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing at a in Fig. 1；
Fig. 3 is the structure sectional view of Composition spacer in the utility model.
Reference:
1 high steam tube head；2 high steam passages；3 Composition spacers；4 blind flanges；5 annular scrap slots；6 stainless steels
Ring；7 graphite annulus.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is further described.Following examples are only used for this is clearly described
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
Of the present utility model description in it is to be understood that term " radially ", " axial ", "left", "right", " on ",
The orientation of instruction such as D score, " top ", " bottom ", " interior ", " outward " or position relationship are based on orientation shown in the drawings or position relationship,
It is for only for ease of description the utility model and simplifies description, rather than the device of instruction or hint indication or element must have
Specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.New in this practicality
In the description of type, unless otherwise stated, the implication of " multiple " and " some " refers both to two or more.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", " setting ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or integratedly
Connect；Can be to be joined directly together it is also possible to be indirectly connected to by intermediary.For the ordinary skill in the art,
Concrete meaning in the utility model for the above-mentioned term can be understood as the case may be.
As shown in Figures 1 to 3, a kind of high steam sealing device, comprising:
High steam tube head 1, inside has high steam passage 2, and one end is machined with countersunk head screwed hole；
Blind flange 4, realizes sealing for being assemblied in the countersunk head screwed hole of high steam tube head 1 end, outside its head
Wall is machined with external screw thread；Offering two cross sectional shapes on its end face of flange is semicircle or triangle annular scrap slot 5；Its
Outer end is machined with inner hexagonal hole；
Composition spacer 3, it is set between end face of flange and countersunk head screwed hole step end face；It is by some stainless steel rings 6
Radially nestable with graphite annulus 7 form, its periphery and inner headed face are stainless steel ring 6.
In Composition spacer 3,6 skeleton functions of stainless steel ring, between the stainless steel ring 6 of different-diameter, graphite annulus 7 is set,
Because graphite is softer thus can preferably be in close contact with two sealing surfaces in extruding, the fallen stone due to extruding
Ink bits then can be accumulated in annular scrap slot 5 and form second sealing, improve sealing property further.
The above is only preferred embodiment of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from the utility model know-why, some improvement can also be made and deform, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
