Description
Technical field
The utility model belongs to natural gas standpipe field, and in particular to a kind of for blocking the poly- second of natural gas standpipe casing
Alkene pyrocondensation cap.
Background technique
The gap between natural gas standpipe casing and gas pipeline mostly uses spunyarn to clog greatly at present, and white cement blocks pipe
Mouthful.The waterproof seal of white cement is poor, causes natural gas standpipe perishable, influences the service life of natural gas standpipe, gives user
It brings inconvenience.
Utility model content
The utility model provides a kind of novel device for being used to block natural gas standpipe casing, can effectively solve casing envelope
Stifled the phenomenon that sternly gas pipeline not being caused to corrode.
The utility model it is a kind of for blocking the polyethylene pyrocondensation cap of natural gas standpipe casing comprising one for covering
Enter natural gas standpipe casing and bond natural gas standpipe casing and diameter be slightly larger than the cylinder-shaped big end of natural gas standpipe casing
End and big end end are integrally formed and diameter is between natural gas standpipe casing and natural gas standpipe and natural for bonding
The cylinder-shaped small end end of gas standpipe, big end end assume a " convex " shape with small end end and connect, polyethylene pyrocondensation cap from inside to outside according to
Secondary is the bottom being made of fusion bonded epoxy priming paint, the middle layer being made of adhesive and the surface layer being made of extruded polyethylene.
Preferably, the diameter of big end end is 12-18mm bigger than natural gas standpipe casing diameter, e.g., about 15mm, length
For 80-120mm, e.g., about 100mm.
Preferably, the diameter of small end end is 12-18mm bigger than natural gas standpipe diameter, e.g., about 15mm, and length is
60-100mm, e.g., about 80mm.
Preferably, bottom with a thickness of 1.0-1.5mm, e.g., about 1.2mm, intermediate layer thickness 1.0-1.5mm, such as
About 1.2mm, surface thickness 2.2-2.9mm, e.g., about 2.2mm.
The main function of bottom fusion bonded epoxy priming paint is: forming continuous film, directly bonds with steel tube surface, has very
Good chemical corrosion resistance and antikathode stripping performance；It reacts to form chemical bonding with middle layer adhesive, guarantees whole anti-corrosion
Layer has good caking property at relatively high temperatures.Middle layer is preferably copolymer binder, and main component is polyolefin, gluing
Agent and epoxy primer generate chemical reaction, and middle layer and bottom is made to form good bonding；And adhesive and surface layer extrusion molding are poly-
Ethylene has good affinity interaction, so that middle layer and surface layer also have good adhesive property.To rise mechanical protection with
Antisepsis.
The use process of the polyethylene pyrocondensation cap of the utility model are as follows:
At the construction field (site) in natural gas standpipe work progress, according to the natural gas standpipe size of design drawing mark and natural
Gas standpipe casing size selects the polyethylene pyrocondensation cap of different model, and natural gas line is before every layer of welding by polyethylene
Pyrocondensation cap pierces into pipeline, completes after gas riser welding and chooses flexible material (such as: spunyarn) after fixation to through-flooring
Casing is blocked, and then polyethylene pyrocondensation cap big end end is buckled on casing, using gas tank and grilled gun to polyethylene heat
Contracting cap is heated, and polyethylene pyrocondensation cap is while radial contraction, middle layer adhesive melts, makes three layers of polyethylene pyrocondensation cap
Structure is tightly coated on gas pipeline and sleeve surface, forms continuous closely preserving and sealing system.Effective solution because
Casing closure does not lead to the phenomenon that kitchen infiltration and gas pipeline corrosion sternly.
The polyethylene pyrocondensation cap of the utility model connects silk, welded pipe line can be applicable in.
The utility model has the beneficial effects that
The polyethylene pyrocondensation cap of the utility model has corrosion-resistant, soaking-resistant, and long service life, waterproof seal are good,
Simple installation, quick, contraction speed is fast, is easy to the features such as constructing.
Detailed description of the invention
Fig. 1 is a kind of for blocking the structural representation of the polyethylene pyrocondensation cap of natural gas standpipe casing of the utility model
Figure.
Fig. 2 is the partial enlarged view at I.
Description of symbols:
1- big end end, 2- small end end, 3- bottom, 4- middle layer, 5- surface layer.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawing.
As shown in Figure 1, the utility model is a kind of for blocking the polyethylene pyrocondensation cap of natural gas standpipe casing comprising
One bonds the circle that natural gas standpipe casing and diameter be slightly larger than natural gas standpipe casing for being inserted in natural gas standpipe casing
Tubular big end end 1 and big end end are integrally formed and diameter is in and is used in combination between natural gas standpipe casing and natural gas standpipe
In the cylinder-shaped small end end 2 of bonding natural gas standpipe, big end end 1 assumes a " convex " shape with small end end 2 and connect, as shown in Fig. 2,
Polyethylene pyrocondensation cap be successively from inside to outside the bottom 3 being made of fusion bonded epoxy priming paint, the middle layer 4 being made of adhesive and by
The surface layer 5 that extruded polyethylene is constituted.
The diameter of big end end 1 is 12-18mm bigger than natural gas standpipe casing diameter, e.g., about 15mm, length 80-
120mm, e.g., about 100mm.
