Abstract
The making process of integral GRP T-pipe includes the following steps: making branch pipe mold including one straight pipe section and one curved section in the curvature radius the same as that of the main pipe mold with smooth transition fillet in between; making the GRP branch pipe and flash through molding with the branch pipe mold, curing and demolding; fixing the branches with flash to the main pipe mold; making the main GRP pipe to close the branch pipe flashes through molding, curing and demolding. The integral GRP T-pipe has no seams between the branch pipe and the main pipe, high corrosion resistance, high anti-leakage performance, small flow resistance and other advantages.
Description
Technical field
The present invention relates to a kind of fiberglass threeway, particularly a kind of making process of integral GRP T-pipe.
Technical background
Fiberglass threeway manufacture craft of the prior art has dual mode: 1, perforate threeway, promptly on being responsible for, leave the hole that will connect, and arm is bonded on the person in charge.The cutting of perforate and branch pipe intersecting line on being responsible for of this kind technology is difficult, and arm generally can not well coincide at the intersection place with being responsible for, and has the slit.For small-sized threeway, the bad further processing of inner-seam, thereby influence the decay resistance and the barrier performance of threeway.In addition, this kind perforate threeway mode, arm adopts the especially small-sized threeway of round-corner transition with being responsible for connection place inconvenience, and flow resistance is bigger, and the fluid that has abrasive nature for conveying may produce undue wear and the destruction of causing threeway to the connection place; 2, the whole threeway of combination die, this kind threeway adopts soft rubber as external mold, the dismountable steel core of inner insertion.Earlier mould is assembled during making, externally make whole fiberglass threeway then, solidify the back and earlier steel core is taken out, again rubber mold is taken out.The whole threeway moulding process of this kind is suitable for the making of single-piece threeway, for the goods that a plurality of threeways are arranged on same goods, because small product size is bigger, and the Mold Making difficulty, the cost height, operation inconvenience can't be used.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, has proposed the whole threeway manufacture craft of a kind of new glass fibre reinforced plastic.It does not have seam at arm and between being responsible for, and can make a plurality of whole threeways on request on the same person in charge.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of making process of integral GRP T-pipe, be characterized in: at first make manifold die, manifold die comprises one section Zhi Guanmo and one section radius of curvature and the identical cambered surface of person in charge's mode radius, Zhi Guanmo and cambered surface perpendicular quadrature, it passes through the junction mutually and is provided with and seamlessly transits fillet; Produce whole fiberglass arm and limit, door leaf thereof at Zhi Guanmo outer surface on the manifold die and the circle that joins with it on the cambered surface, treat curing and demolding; The fiberglass arm on the limit, band door leaf after the demoulding is fixed with being responsible for mould, limit, door leaf and person in charge's mould cylindrical are coincide; Make fiberglass then and be responsible for, the limit, door leaf of fiberglass arm is wrapped in the person in charge curing and demolding.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, be provided with fixture between the fiberglass arm on band limit, door leaf and the person in charge's mould, described fixture is provided with a detachable stay-bolt that is connected with person in charge's mould, and the upper end of stay-bolt is provided with clamp nut and platen.
The present invention compared with prior art, with the fiberglass arm on band limit, door leaf be responsible for the integral manufacturing fiberglass threeway of the fixing back of mould, do not have seam between arm and the person in charge, thereby inside do not need to handle again, decay resistance and barrier performance are good; Arm can adopt big round-corner transition with person in charge connection place, and the fillet size can be made on request, and flow resistance is less; Can make a plurality of whole threeways on request on the same person in charge, make easily, mould is simple, less investment.

The specific embodiment
A kind of making process of integral GRP T-pipe, at first make manifold die 10, manifold die 10 comprises one section Zhi Guanmo 1 and one section radius of curvature and the identical cambered surface 2 of person in charge's mould 9 radiuses, Zhi Guanmo 1 and cambered surface 2 perpendicular quadratures, it passes through the junction mutually and is provided with and seamlessly transits fillet, and the fillet size can be made on request; Produce whole fiberglass arm 3 and limit, door leaf 4 thereof at 1 outer surface of the Zhi Guanmo on the manifold die 10 and the circle that joins with it on the cambered surface 2, treat curing and demolding; The fiberglass arm 3 on the limit, band door leaf 4 after the demoulding is fixed with being responsible for mould 9, limit, door leaf 4 and person in charge's mould 9 cylindricals are coincide; Make fiberglass then and be responsible for 8, the limit, door leaf 4 of fiberglass arm 3 is wrapped in be responsible in 8 curing and demolding.
Be provided with fixture between the fiberglass arm 3 on band limit, door leaf 4 and the person in charge's mould 9, described fixture is provided with a detachable stay-bolt 5 that is connected with person in charge's mould 9, can on person in charge's mould 9 tube walls, have through hole, stay-bolt 5 is outwards passed from being responsible in the mould 9, to push down with the fiberglass arm 3 on limit, door leaf 4 with platen 7, compress with clamp nut 6 then.
