Description
Technical field
The present invention relates to a kind of glass fibre Wound Pressure Vessels and processing method thereof.
Background technique
As shown in Figure 2, existing glass fibre Wound Pressure Vessels 1 ' by inner bag 12 ' and the threaded coupling 11 ' institute of its top or bottom form, be the pressurized container that is filled with water in a kind of softened water treatment device.The threaded coupling 11 of similar this glass fibre (being glass fibre reinforced plastics) Wound Pressure Vessels ' accessing to 12 ' time of inner bag, because the seal ring 3 on the valve body 4 compresses with threaded coupling 11 top/bottom, its sealability depends on threaded coupling 11 and the intensity of inner bag 12 fusions and the integrity of face of weld fully.In this pressurized container 1 actual use, rise and fall along with pressure, whole pressurized container has micro-breathing, do not reach ideally or pressurized container after integrity is damaged after doing the time than the farm labourer at heat seal strength, water can ooze out from the slit 5 of the face of weld of being damaged, and causes the inefficacy of pressurized container.
Summary of the invention
For solving the hidden danger defective that above-mentioned threaded coupling sealing exists, the object of the present invention is to provide a kind of kind glass fibre Wound Pressure Vessels and the processing method thereof that can move reliably and with long-term.
A kind of glass fibre Wound Pressure Vessels provided by the present invention, comprise the threaded coupling of fixedlying connected in the mouth neck portion place of inner bag and its top or bottom, it is characterized in that: described threaded coupling outer side surface is provided with anti-fall locating slot and the anti-rotation blind hole that several hoops distribute, and the top has annular shallow slot; Described inner-tube mouth neck is coated on outside the described threaded coupling, and both are that concavo-convex cooperation is fused into one in the junction.
The method of a kind of processed glass fiber Wound Pressure Vessels provided by the invention comprises the following steps: the threaded coupling screw-in of molding and forming is in advance played on the core of this threaded coupling to central role; In the blowing mode material is extruded, and be inserted in threaded coupling; Carry out matched moulds, have on the mould with shaping structures after consistent inserts, blow moulding and forming; To drive threaded coupling together downward when bottomed cylinder pulling core, and the threaded coupling bottom surface is closely contacted with inner bag, fuses fully.
The method of a kind of processed glass fiber Wound Pressure Vessels that the present invention also provides, the threaded coupling that comprises the following steps: molding and forming in advance screw on the screw thread plug that exotic material makes; The screw thread plug is released by clamp in advance and is blocked, and the screw thread plug is return; Mold heated is to set point of temperature, and the powder in the mould has been melted in mould inner surface, forms inner bag; Clamp is extracted in the cylinder action out, and the screw thread plug rebounds under the effect of spring, and the screw thread plug is pulled, and screw thread plug and setting sleeve and sliding positioning sleeve are close to, and unnecessary melt in the cavity is extruded, and finish the fusion of threaded coupling and inner bag; According to shape moulding in the cavity, unclamp screw, the screw thread plug of outwarding winding, the screw thread plug screws out with sliding positioning sleeve, obtains complete threaded coupling shape.
Adopted above-mentioned technical solution, the mouth neck portion that is inner bag encases threaded coupling, threaded coupling is provided with a plurality of anti-fall locating slots and anti-rotation blind hole, the top has shallow slot, help the prolongation in the path of the weld length of inner bag and threaded coupling and seepage like this, in addition, when screwing the valve body that is inserted in the threaded coupling, by compressing the seal ring collet threaded interface top/bottom on the valve body and the gap of inner bag, make the tight pressing of inner bag and threaded coupling, cut off the loop that leaks fully.If weld lost efficacy under given conditions, water also is to flow back in the container.Therefore, the present invention has reached zero seepage in to the test of container seepage, thereby makes the long-time running of this pressurized container that reliable guarantee be arranged.

Embodiment
As shown in Figure 3, Figure 4, glass fibre Wound Pressure Vessels of the present invention comprises the threaded coupling of fixedlying connected in mouth neck portion 121 places of inner bag 12 and its top or bottom 11, wherein:
The outer side surface of threaded coupling 11 is provided with anti-fall locating slot 111 and the anti-rotation blind hole 112 that several hoops distribute, and the top has annular shallow slot 113;
Inner-tube mouth neck 121 is coated on outside the described threaded coupling 11, and both are concavo-convex cooperation welding in the junction.
When screwing the valve body 4 that is inserted in the threaded coupling 11, by compressing seal ring 3 collet threaded interfaces, 11 end faces on the valve body 4 and the gap of inner bag, make inner bag 12 and the tight pressing of threaded coupling 11 end faces, cut off the loop that leaks fully.If weld lost efficacy under given conditions, water also flows back in the inner bag 12 by direction shown in Figure 3.
As shown in Figure 1, the inner bag 12 of glass fibre Wound Pressure Vessels 1 of the present invention that is: provides preformed threaded coupling 11 by injection moulding by blowing or rotationally molding, when forming inner bag 12, preformed joint and inner bag are fused into one, form a kind of complete sealing configuration.
(1) method of employing blow moulding and forming:
Shown in Fig. 5, Fig. 5 A, Fig. 5 B, the threaded coupling 11 of molding and forming in advance screws on the core 51.In the blowing mode material is extruded, is inserted in threaded coupling 11, carry out matched moulds, have on the mould 50 with shaping structures after consistent inserts 52, blow moulding and forming; Core 51 play threaded coupling 11 to central role, to drive threaded coupling 11 together downward when bottomed cylinder 53 pulling cores 51, and threaded coupling 11 bottom surfaces are closely contacted with inner bag 12, fuses fully.
