Detailed description of the invention
Just by reference to the accompanying drawings the present invention is described further below.
As shown in Figure 1, space station of the present invention potable water long storage periods water tank, comprises capsula interna 1, external capsule 2, slide fastener 3, elastic cord 4, quick disconnect 5, gut threads 6, adapter 7, exit pedestal 8, capsula interna water outlet 10, capsula interna end face heat seal place 11, capsula interna end face 12, product indicia bag 13, mark bag 14 for subsequent use, liquid level index strip overcoat 15, circumferential stiffening band 16, axial stiffening band 17, accommodating parts bag 18, off-duty storage bag 19; External capsule 2 and capsula interna axial plane 1 are cylindrical, and the material of external capsule is that chitin fiber cloth belongs to non-metallic material; The material of exit pedestal 7 is non-metal.
Outlet for polyethylene pedestal 8 utilizes together with heat seal process is bounding to nine layers of complex film capsula interna axial plane 1, and evenly, firmly, outward appearance, without focal spot, brilliant point, water mark, foreign matter, ensures that space water tank filling process and storage process can not be revealed in heat seal place.The film body of exit pedestal 8 and nine layers of complex film heat seal place removes the circle of a diameter 20mm, and the removal part circular center of circle and the exit pedestal 8 pod apertures center of circle correspond to a bit.Capsula interna axial plane 1, capsula interna end face 12 are nine layers of composite film material as the parts directly contacted with astronaut's potable water, it is the key of long storage periods water, but capsula interna axial plane 1, capsula interna end face 12 can not as pressure-containing members, therefore design external capsule 2 structure and be used as pressure-containing member, when water tank inside is full of liquid, water tank internal pressure is delivered to external capsule 2, ensure that the requirement of strength of water tank.When the non-filling liquid of water tank, inside is in the state of vacuumizing, and along with increasing of filling liquid, capsula interna 1, capsula interna end face 12 slowly expand and fit on external capsule 2.
As shown in Figure 3, quick disconnect 5 is used for soft tank as quick separating interface and is connected with the quick of space station, quick disconnect 5 is connected with exit pedestal 8 by adapter 7, and adopt gut threads 6 to fix in quick disconnect 5 and adapter 7 junction, exit pedestal 8 water inlet 9 is connected with capsula interna 1.
Fiber cloth supports external capsule 2 and adopts chitin fiber cloth to be made, and this fiber cloth not only mechanical property meets the operating needs of water tank, also with several functions such as antibacterial, fire-retardant, mildew-resistant, emergent gas are nontoxic.
When water tank inside, space uses in space after being full of liquid, internal liquid can be carried by peristaltic pump, and along with the minimizing of soft tank internal liquid, flexible water tank external capsule 2 reduces gradually.
As shown in Figure 4, exit pedestal 8, quick disconnect 5 joint adopt the design of locking and labyrinth seal structure, and maze trough adopts cone tank design to prevent adapter from loosening, and three taper conduits can play the effect of labyrinth packing simultaneously, prevent from revealing.Taper flute length is L=3mm, groove depth (D1-D2) * 0.5=0.75mm.Adjacent conical groove interval 4mm.Exit pedestal 8 and quick disconnect adopt transparent medical PVC pipe to be connected, the external diameter 2mm larger than pvc pipe internal diameter of exit pedestal 8, quick disconnect 5 joint.The width of seal face is h=1mm.
Adopt wire winding to reinforce in adapter 7 and exit pedestal 8 and quick disconnect 5 junction, avoid adapter 7 to loosen and produce leakage.As shown in Figure 5, adopt spiral wound mode during coiling, two adjacent astragals are closely connected method for winding, finally adopt the U-shaped line put well in advance to fix the other end of gut threads 6.
The external capsule 2 of flexible water tank and capsula interna 1 can store and transport in split.External capsule 2 is arranged slide fastener 3 structure, so that the assembling of capsula interna 1 and external capsule 2 and fractionation.
Flexible water tank external capsule 2 axially arranges 3 reinforced ribs on the face of cylinder and circumference arranges 2 reinforcing rib structures, and this reinforcing rib structure is that employing 4 layers of fiber cloth are made and formed, and width is 60mm.Reinforcing rib structure design improves fiber cloth strained condition, makes fiber cloth uniform force, reduces water tank axis and diametric deflection.
As shown in Figure 6, soft tank external capsule 2 both ends of the surface arrange equilateral 6 limit shape structures in the half position of radius, arrange radial constraint in diametric(al) every angle A=60 degree.Designed by end face restraining structure, the excessive water tank axial length that causes of the soft tank head face hump after topped up with water can be avoided to exceed standard.
In a word, the present invention can bear higher operating pressure, capsula interna and external capsule can store in split, good with the compatibility of water, have extremely strong gas barrier properties, long service life, external capsule has antibacterial, mildew-resistant characteristic and external capsule Flame Retardancy can be excellent, and structure is simple, has detachable function, can repeatedly use, water tank external capsule and capsula interna stored collapsed can reduce parking space.
The unspecified part of the present invention belongs to general knowledge as well known to those skilled in the art.
