Abstract
The utility model provides a manhole sealing device of high-voltage equipment, which comprises a ball-shaped sealing head, a sealing gasket, an end-part flange, a compact flange and a top cover and has the characteristics that a main bolt hole is arranged at the part on the compact flange and near the outer edge of the compact flange; a drag bolt hole is arranged at the part on the compact flange and near the inner edge of the compact flange; a main bolt hole is correspondingly arranged on the end-part flange; a drag bolt hole is correspondingly arranged on the top cover; a main bolt is connected by the compact flange and the end-part flange; a drag bolt is connected by the compact flange and the top cover; a ring flange is arranged on the bottom surface of the compact flange; the tip of the ring flange is positioned on the sealing gasket arranged between the top cover and the ball-shaped sealing head; and the end-part flange is positioned under the compact flange and pressed on the ball-shaped sealing head. The manhole sealing device has a simple structure and is convenient to process, manufacture and maintain.
Description
Technical field
The utility model relates to high-tension apparatus manhole sealing technique, specifically a kind of high-tension apparatus manhole seal arrangement.
Background technique
At present, the manhole sealing configuration that high-tension apparatus (as high pressure heat exchanger, high-pressure separator) is upward commonly used mainly is seal with double-cone and wood closure.Though these two kinds of structures all belong to self-energized seal, and the history of using on high-tension apparatus is very long, technology is also very ripe, still has the improved place of some needs.The perforate that nominal diameter is identical, the material that the material that the seal with double-cone structure is used is used than the wood closure structure is many, the difficulty of processing of part is big, required precision is high but the wood closure structure is used.The utility model has been made improvement at the shortcoming of above two kinds of structures, the advantage of the two is effectively combined, not only saved material but also avoid highly difficult manufacturing requirement, can effectively save material, reduce manufacture cost, for company brings considerable economic.
Summary of the invention
The utility model provides a kind of high-tension apparatus manhole seal arrangement at the problem that prior art exists, and it is simple in structure, is convenient to manufacturing, and is easy to maintenance.
The purpose of this utility model is achieved through the following technical solutions: a kind of high-tension apparatus manhole seal arrangement, comprise dome head, sealing gasket, end flange, supported flange, top cover, it is characterized in that near outer rim the kingbolt hole being set on the described supported flange, pin down bolt hole near the inner edge setting on the supported flange, corresponding kingbolt hole is set on the described end flange, the corresponding bolt hole that pins down is set on the described top cover, connect supported flange and end flange by kingbolt, connect supported flange and top cover by pining down bolt, described supported flange is provided with annular flange flange on the bottom surface, annular flange flange withstands on the sealing gasket between top cover and the dome head, and end flange is positioned at the supported flange below and is pressed on the dome head.
To improvement of the technical scheme: described sealing gasket is the integrative-structure that elastic material is made.The utility model compared with prior art has many advantages and good effect:
1. the utility model has reduced the sealing configuration part, has both saved material, has reduced the highly difficult requirement of manufacturing again, thereby has saved manufacture cost.
2. the utility model adopts elastic sealing gasket, can avoid because the excessive conquassation sealing surface of impacting force influences the sealing of equipment.
3. the utility model is simple in structure, is convenient to assembling and dismounting, can be used for the manhole of frequent open and close on the high-tension apparatus.
Description of drawings
The local mounting structure figure of Fig. 1 novel high-pressure equipment manhole seal arrangement.
Embodiment
Be described further below in conjunction with accompanying drawing 1 the utility model.
Referring to Fig. 1, the embodiment of a kind of high-tension apparatus of the utility model (as high pressure heat exchanger, high-pressure separator) manhole seal arrangement, mainly by dome head 1, sealing gasket 2, end flange 3, supported flange 4, kingbolt 5, pin down bolt 6, top cover 7 is formed.
Near outer rim the kingbolt hole is set on the described supported flange 4, pins down bolt hole near the inner edge setting on the supported flange 4, corresponding kingbolt hole is set on the described end flange, the corresponding bolt hole that pins down is set on the described top cover.Connect supported flange 4 and end flange 3 by kingbolt 5, connect supported flange 4 and top cover 7 by pining down bolt 6.Described supported flange is provided with annular flange flange on 4 bottom surfaces, and annular flange flange withstands on the sealing gasket 2 between top cover 7 and the dome head 1, and end flange 3 is positioned at supported flange 4 belows and is pressed on the dome head 1.
The utility model is introduced the compressing structure in the seal with double-cone, realizes the sealing of equipment by fastening piece kingbolt 5.On supported flange 4, process flange and pin down bolt hole.Flange can replace four cyclizations in the wood closure, plays the effect that compresses sealing gasket 2; Process pin down bolt hole after, can make supported flange 4 replace pining down ring in the wood closures, pin down bolt 6 by preload piece and pin down top cover 7, sealing gasket 2.
In addition, sealing gasket 2 usefulness elastic materials are made, and can avoid causing the pad plastic deformation after the pressure increase, can not return to original shape after unloading, and influence the sealability of equipment.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example.Those skilled in the art are in essential scope of the present utility model, and the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
Claims (2)
1. high-tension apparatus manhole seal arrangement, comprise dome head, sealing gasket, end flange, supported flange, top cover, it is characterized in that near outer rim the kingbolt hole being set on the described supported flange, pin down bolt hole near the inner edge setting on the supported flange, corresponding kingbolt hole is set on the described end flange, the corresponding bolt hole that pins down is set on the described top cover, connect supported flange and end flange by kingbolt, connect supported flange and top cover by pining down bolt, described supported flange is provided with annular flange flange on the bottom surface, annular flange flange withstands on the sealing gasket between top cover and the dome head, and end flange is positioned at the supported flange below and is pressed on the dome head.
