Abstract
The present invention relates to a pressure container wound by glass fibers and a processing method thereof. The pressure container comprises a liner and a close nipple, wherein the outer side surface of the close nipple is provided with a plurality of positioning grooves preventing glide and distributed in an annular direction and blind holes preventing rotation, and the top is provided with an annular shallow groove; the neck part of a liner opening is coated outside the close nipple, and the neck part and the close nipple are in concave convex fit at the combination point to be fused into a whole body. The present invention is favorable to prolong the length of the fused point of the liner and the close nipple and a path for leaking water. In addition, when the pressure container is screwed and inserted into a valve body in the close nipple, a gap of the top surface/ bottom surface of the close nipple and the liner is impacted by impacting a sealing ring on the valve body, the liner and the close nipple are close stuck and impacted, and a water leaking loop is completely cut off. If the fused point fails under some specific conditions, water also flows back to the container. Therefore, the present invention achieves zeroth leakage in a leakage performance experiment of the container, and thereby, the long-time operation of the pressure container is reliably ensured.
Description
Technical field
The present invention relates to a kind of glass fibre Wound Pressure Vessels.
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 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.
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.
(2) method of employing rotationally molding
Shown in Fig. 6 A, Fig. 6 B, on the screw thread plug 61 that the threaded coupling 11 screw-in exotic materials of molding and forming are in advance made, screw thread plug 61 is released in advance by clamp 62 and is blocked, and screw thread plug 61 is return.Mould 6 is heated to set point of temperature, powder 63 in the mould 6 has been melted in mould 6 internal surfaces 64, form inner bag 12, clamp 62 is extracted in cylinder 65 actions out, screw thread plug 61 rebounds under the effect of spring 66, screw thread plug 61 is pulled, and screw thread plug 61 is close to setting sleeve 67 and sliding positioning sleeve 68, and unnecessary melt in the cavity is extruded, finish the fusion of threaded coupling 11 and inner bag 12, according to shape moulding in the cavity.Unclamp screw 69, the screw thread plug 61 of outwarding winding, screw thread plug 61 screws out with sliding positioning sleeve 68, obtains complete threaded coupling 11 shapes.
