Description
Technical field
The present invention is applied to the leak stopping sealing of glass reinforced plastic pipe, is particularly suited for larger-diameter glass reinforced plastic pipe leak stopping
Sealing.
Background technology
Glass reinforced plastic pipe belongs to fragility material, and anti-impact force is small, is squeezed and is also easy to produce the damaged leakage of crackle.Using
Bond patching, need thorough cleaning pipe surface, brushing resin, paste structure sheaf, paving glass fabric,
The multiple operations such as solidification, polishing are repeated several times, and can come into operation after need to standing 24 hours, down time
It is long.And underground is installed on pipeline more, and increase difficulty to repair.
The content of the invention
It is an object of the invention to provide a kind of LARGE DIAMETER FRP tube packing function leak-stopping sealing device, soft packing
A kind of improved structure of letter sealing, filler is made up of asbestos cord and " O " shape rubber ring, with good airproof performance,
Repair amount is small, the characteristics of down time is short.
To reach above-mentioned purpose, the technical scheme is that：
A kind of LARGE DIAMETER FRP tube packing function leak-stopping sealing device, it is characterized in that：Including glass reinforced plastic pipe B1,
B2, flanged (FLGD) steel pipe G1, G2, filler, stuffing-box, gland, described flanged (FLGD) steel pipe G1,
G2 ends are provided with stuffing-box 1,2, and its end is extend into glass reinforced plastic pipe B1, B2, described stuffing-box 1,
The filler of asbestos cord and round section joint ring composition is provided between 2 and glass reinforced plastic pipe B1, B2 ends, described fills out
Material letter is externally provided with gland.
The beneficial effects of the invention are as follows：Using stuffing box type sealing structure leak stopping, because fiberglass belongs to fragility material,
It is squeezed frangible, glass steel member is difficult processing and manufacturing, from flanged steel pipe and metallic stuffing box as filling out
Expect that the main member of function sealing device is easy to processing, while steel pipe plays a supportive role to glass reinforced plastic pipe, it is to avoid
Glass reinforced plastic pipe extrusion is damaged.Filler is asbestos cord and round section joint ring, soft packing seal and extrusion forming
Seal combination is used, and sealing effectiveness is more preferable.Can be put into after the manufacture installation of stuffing box type sealing device makes
With.Workload and difficulty are reduced, and repair time greatly shortens.Continuously use No leakage, sealed reliable.
Solve bonding repairing method operation complicated, repair that difficulty is big, down time problem long.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Referring to accompanying drawing 1, the present invention includes glass reinforced plastic pipe B1, B2, flanged (FLGD) steel pipe G1, G2, filler,
Stuffing-box, gland, described flanged (FLGD) steel pipe G1, G2 end is provided with stuffing-box 1,2, and its end is stretched
Enter in glass reinforced plastic pipe B1, B2, set between described stuffing-box 1,2 and glass reinforced plastic pipe B1, B2 ends
The filler being made up of asbestos cord and round section joint ring, described stuffing-box is externally provided with gland.
1st, fiberglass steel pipe cracking failure part is removed, two ends are cleaned out.
2nd, a diameter of Φ 16 of " O " shape rubber ring, material determines according to sealing medium and temperature.
3rd, steel pipe G1, G2 and stuffing-box material are chosen according to sealing medium.
4th, according to glass reinforced plastic pipe outer diameter D 1, and round section joint ring sectional shrinkage 15%-20% is determined in stuffing-box
Footpath D2.
5th, according to glass reinforced plastic pipe internal diameter D3, selection carbon steel pipe outer diameter D 4, its radial clearance 2-3mm.
6th, packed height H is 80-120mm, is chosen according to pressure medium.
7th, root tool dimensions above prepare stuffing-box, steel pipe G1 (flanged), steel pipe G2 (flanged) and
Gland, stuffing-box 2 is welded to connect with steel pipe G2, and stuffing-box 1 is placed on carbon steel pipe G1, treats steel pipe G2
And welded after G1 positioning.
8th, steel pipe G1 and gland are loaded on B2 loaded on glass reinforced plastic pipe B1, G2 and gland, and make B2 ends
It is inserted to stuffing-box bottom surface
9th, after steel pipe G2 and G1 positioning, stuffing-box 1 is welded as shown in the figure with steel pipe G1, asbestos cord
Fill in stuffing-box, filling height is H, and rubber ring is placed on it, installs gland.After the completion of can input make
With.
It should be noted that implementation method of the present invention is only to realize preferred embodiment of the invention, it is right
Belong to general idea of the present invention, and be only obvious change, protection scope of the present invention all should be belonged to
Within.
