Abstract
The utility model provides an industrial furnace boiler tube hydrostatic test mouth of pipe seal structure, is including sealed blind plate, steel pipe, sealed blind plate on to be provided with the cylinder type protruding, protruding surface be provided with the slot that 1 -2 is used for assembling O type circle, sealed blind plate and steel pipe terminal surface connection place be provided with nonmetal plain washer to couple through the bolt, the arch on have a fillet. The utility model discloses an industrial furnace boiler tube hydrostatic test mouth of pipe sealing device's repeatedly usable is showing and is reducing manufacturing cost, has also improved sealing performance simultaneously greatly.
Description
Technical field
The utility model relates to a kind of orifice sealing device, relates in particular to a kind of industrial furnace boiler tube hydrostatic test ferrule structure reused.
Background technique
Current domestic and international industrial boiler tube hydrostatic test orifice sealing device many employing welding blind plate sealing mouth of pipe, this orifice sealing device is more original, is used for boiler tube and leaves enough hydraulic pressure surpluses, and the occasion that steel pipe easily cuts.The boiler tube hydrostatic test orifice sealing device device that welding blind plate makes cannot be reused, and cost of production is relatively high, and the hydrostatic test operates length consuming time, and manufacturing efficiency is low, and labor strength is large.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the utility model provides a kind of industrial furnace boiler tube hydrostatic test ferrule structure.
The technical solution adopted in the utility model is, a kind of industrial furnace boiler tube hydrostatic test ferrule structure, comprise sealing blind, steel pipe, described sealing blind is provided with cylinder type projection, described convex surfaces is provided with 1-2 for assembling the groove of O type circle, described sealing blind and Steel pipe end surface connection place are provided with nonmetal plain washer, and pass through Bolt Connection; Described projection is rounded down.
The utility model O type circle is assemblied in the groove at the protruding column position of sealing blind, and groove number is 1 ~ 2, achieves the radial seal of steel pipe; Nonmetal plain washer is loaded on sealing blind and Steel pipe end surface connection place, and fits with sealing blind, achieves the end face seal of steel pipe.
The beneficial effects of the utility model are, achieve the reusable of industrial furnace boiler tube hydrostatic test orifice sealing device, significantly reduce cost of production, also substantially increase sealability simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. sealing blind, 2. nonmetal plain washer, 3.O type circle, 4. steel pipe 5. is protruding.
Specific embodiments
With reference to Fig. 1, by sealing blind (1) the nonmetal plain washer of upper assembling (2), and 1 ~ 2 groove for assembling O type circle (3) assembles suitable O shape circle (3), by the port of sealing blind (1) press-in steel pipe (4) after assembling, and lock by Bolt Connection, contact with steel pipe (4) the inwall Light deformation that produces of O type circle (3) makes O type circle (3) and steel pipe (4) inwall close contact, after passing into high pressure water in steel pipe (4), O type circle (3) distending lip limit under the effect of pressure testing high pressure water realizes the sealing to steel pipe (4) internal diameter.But not metallic flat gasket (2) achieves sealing blind (1) and the end face seal of steel pipe (4), seals reliable.After the hydrostatic test terminates, dismounting sealing blind (1), next time can reuse.
Claims (3)
1. an industrial furnace boiler tube hydrostatic test ferrule structure, comprise sealing blind (1), steel pipe (4), it is characterized in that: described sealing blind (1) is provided with cylinder type projection (5), described convex surfaces is provided with the groove for assembling O type circle (3), described sealing blind (1) and steel pipe (4) end face connection place are provided with nonmetal plain washer (2), and pass through Bolt Connection.
2. a kind of industrial furnace boiler tube hydrostatic test ferrule structure according to claim 1, is characterized in that: described projection (5) is rounded down.
3. a kind of industrial furnace boiler tube hydrostatic test ferrule structure according to claim 1, is characterized in that: described is 1-2 for assembling the groove of O type circle (3).
