(3) summary of the invention
Have above-mentioned deficiency in the existing technology in order to overcome, the utility model provide a kind of simple in structure, be convenient to the pressure water storage barrel that flexible liner bag son is changed, cost is low.
The technological scheme that the utility model solves its technical problem is: a kind of pressure water storage barrel; Comprise staving and be located at flexible liner bag in this staving, this flexible liner bag is provided with sack, forms water cavity in this flexible liner bag; Form air cavity between this flexible liner bag and the said staving; Said staving is provided with the air-valve assembly that is communicated with extraneous and said air cavity and is communicated with intake-outlet and the pressure-limit valve assembly of said water cavity, also comprises a mouthpiece, is provided with through hole in this mouthpiece; Upper end in this through hole is provided with internal thread; Said pressure-limit valve assembly is provided with outside thread outward, thus the upper end of said mouthpiece match with said outside thread through said internal thread and be screwed onto on the said pressure-limit valve assembly, the lower end of said mouthpiece is connected with said sack.
Further; Said flexible liner bag is a multi-layer structure; Be to interlock by nylon film BOPA layer and polyethylene film PE layer to be formed by stacking; Its nylon film POBA compares with other films, has the advantage that biaxial tension intensity is high, the feature of environmental protection is good, and has excellent toughness, paracentesis resistance, heat resistance, oil resistance, grease resistance and chemical solvent resistance and have fabulous gas (oxygen, nitrogen, carbon dioxide) barrier; Simultaneously, be convenient to processing, can apply or compound etc. with other base materials, cost is low.Its polyethylene film PE ductility and thermal fusion welding property are good, are convenient to shaping operation.Nylon film BOPA layer and polyethylene film PE layer match, and make flexible liner bag have compressive strength height, durable, long service life, be convenient to make, cost is low and advantage such as environmental protection, and long-term the use, the water free from extraneous odour.Said flexible liner bag is a five-layer structure, and structure is more firm.
Further, convex with bulge loop outside the lower end of said mouthpiece, said sack is connected on the said bulge loop through ultrasonic welding.
Further, be provided with the pipe that is connected with said intake-outlet through said pressure-limit valve assembly in said flexible liner bag, convex with one snap ring on the inwall of the lower end of said through hole, this snap ring is clamped on the outer wall of said pipe.
The utility model in use, the sack of flexible liner bag son is threaded on the pressure-limit valve assembly through mouthpiece, during replacing, only needs mouthpiece is screwed down the replacing that can carry out flexible liner bag from the pressure-limit valve assembly, and is very convenient.
Because the sack of flexible liner bag is connected on the bulge loop of mouthpiece firm and reliable connection through ultrasonic welding.
Owing to be provided with a pipe in said flexible liner bag, when water filling in the utility model, water gets into the sub bottom of flexible liner bag by pipe, and water level progressively rises, no longer water filling behind hydraulic pressure inside and outside flexible liner bag and air pressure balance; When discharging water, the pressurized air in the air cavity extrudes the water in flexible liner bag outside the staving by pipe, extrudes waterflow stabilization; When even the water in flexible liner bag is fewer; Current also are very stably, and pipe has the function of equilibrium air pressure and hydraulic pressure, and it is stable to guarantee that current flow out.Owing to snap ring is set in the through hole of mouthpiece, when pipe stretched in the through hole, snap ring was clamped on the outer wall of pipe, made like this that pipe is dismountable to be connected on the mouthpiece, changing the flexible liner bag period of the day from 11 p.m. to 1 a.m, need not pipe is changed together.
The beneficial effect of the utility model is: adopt said structure; On the sack of flexible liner bag, mouthpiece is set; And mouthpiece is threaded through what internal thread and outside thread matched with the pressure-limit valve assembly; Make flexible liner bag son and pressure-limit valve assembly for removably connecting, thereby be convenient to change flexible liner bag, use more convenient, cost is low.
(4) description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the enlarged diagram at the A place of Fig. 1.
(5) embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
With reference to Fig. 1, Fig. 2, a kind of pressure water storage barrel comprises staving 1 and is located at flexible liner bag 2 in this staving 1; This flexible liner bag 2 is provided with sack; These flexible liner bag 2 interior formation water cavities 3 form air cavity 4 between this flexible liner bag son 2 and the said staving 1, and said staving 1 is provided with and is communicated with the external world and the air-valve assembly 5 of said air cavity 4 and the pressure-limit valve assembly 7 that is communicated with intake-outlet 6 and said water cavity 3; Also comprise a mouthpiece 8; Be provided with through hole in this mouthpiece 8, the upper end in this through hole is provided with internal thread 9, the said pressure-limit valve assembly 7 outer outside threads that are provided with; Thereby match with said outside thread through said internal thread 9 and be screwed onto on the said pressure-limit valve assembly 7 in the upper end of said mouthpiece 8; Convex with bulge loop 10 outside the lower end of said mouthpiece 8, said sack is connected on the said bulge loop 10 through ultrasonic welding, firm and reliable connection.
