Description
Technical field
This utility model is related to a kind of on-line pressure sealant clamp structure form and unit construction device, special particularly to one kind
The leakage sealed special fixture of flange sealing surface.
Background technology
The various position such as the equipment in process units, pipeline, valve, when causing leakage because of certain reason, leaking medium band
Warm, with pressure and outside jet flow state.Leakage position：Hole on flange, equipment, pipeline, weld defect, nipple are filled out
Material letter leakage etc..Leaking medium：Water, water vapour, air, oxygen, nitrogen, coal gas, ammonia, liquefied gas, gasoline, diesel oil, kerosene, weight
Oil, lubricating oil, acid, alkali, esters, alcohols, benzene class, various heat carrier, various Hydrocarbon, various chemical gas, liquid etc.
The leakage part of All Media can go to eliminate with this technology.Using the original closed cavity of leakage position, or can leak
The cavity of one closing is set up on position, with the external thrust more than medium system pressure, sealant injects and is full of closes sky
Between, block leakage defect and passage, thus a new sealing structure is set up on leakage position, eliminate letting out of medium
Leakage.Not parking on-line pressure sealant technology is the sophisticated equipment maintenance technique that middle nineteen seventies grow up, when process units and enterprise
During the leakage of the equipment of industry, pipeline various position, can not affect in the case that production carries out, band is warm, with pressure, fast not parking
Speed, reliably and securely stop a leak.
At present, the leakage of process units fluid media (medium) is repaired by not parking on-line pressure sealant technology, how using agent injecting type sealing
Method, implements closure operation., from -180 DEG C～800 DEG C, pressure is from -0.1MPa～35MPa condition for this encapsulating method adaptive temperature
Under the leakage sealed construction of various fluid media (medium)s.But construction procedure is complicated, including fixture mounting and adjusting orientation, injecting operates
It is noted that fltting speed and the coordination of sealant cures time, after completing injecting, carry out effect observation and after-teeming compression.Wherein one
Individual Absent measures are improper will to be affected to block quality, and this not only jeopardizes operating personnel and special equipment safe operation, is also unfavorable for
Resources conservation and environmental conservation.
The flange of tongue and groove, ring joint and taper face seal, referred to as special flange, are characterized in system pressure high pressure
Tight face is little, because stress concentrates intrinsic flange bolt bearing capacity limited.When leakage in this special flange sealing surface
When, if leakage position is contained using general convex flange clamp implement closure, quite on the basis of former sealing, set up broadband close
Envelope,, because lifting surface area is multiplied it is easy to cause former flange bolt overload, not only sealing is difficult to successfully for this, and even
Cause serious accident.

Connecting bolt quantity identical toothed projections；The middle part of described toothed projections axially sets top wire hole；Two neighboring described profile of tooth is convex
Form arc teeth groove, in the middle part of described teeth groove, width is more than flange attaching nut's opposite side size between rising；Described semi-cylindrical shaped portion
It is provided with semi-circular boss in the middle part of inner circumferential, described semi-circular boss is radially provided with injecting hole；Described profile of tooth strengthens plate and institute
State the annular groove that between semi-circular boss, formation is matched with flange outer rim.
This utility model can also adopt the following technical scheme that：
The top end diameter of described toothed projections is less than the top end diameter of described semi-circular boss, the bottom land of described arc teeth groove
End diameter is less than the root diameter (RD) of described semi-circular boss.
The tooth crest of described tooth is arc-shaped concave.
Described top wire hole is centrally located on same circle.
The diameter of a circle that described diameter of a circle is centrally formed with flange bolt hole is identical.
The radially opposite sides in described semi-cylindrical shaped portion are provided with the otic placode with bolt hole.
This utility model has the advantages and positive effects that：A pair of profile of tooth of the present utility model is strengthened plate be respectively sleeved in
Special flange pair, by tightening otic placode bolt, to realize fixture fully identical with flange outer rim for it.And by semi-cylindrical shaped portion
The top wire hole that axial two ends profile of tooth strengthens on plate installs jackscrew, tightens jackscrew and further flange pair top pressure is clamped, thus right
Former flange bolt plays enhancing protective effect, can produce new additional stress because of injecting by active balance flange bolt, both ensure new
Sealing structure can set up operating unit sealing load, prevent flange bolt overload deformation again.Using this utility model it can be ensured that tenon
Groove face, trapezoidal faces, the flange sealing surface leakage injecting seal construction process safety of conical surface seal form.
