On described fluid inlet, be provided with one-way valve.
Compared with prior art, the beneficial effects of the utility model are:
1, modern design, simple in structure, with low cost, efficiency is high.In the utility model, in fluid tank, be provided with air bag, on air bag, be provided with the admission line being connected with the pipeline of gas pressure source and the exhaust duct being connected with atmosphere, when work, utilize pressurized gas to bladder, the air bag of pressurising has been realized the extruding of convection cell, cancel the device such as motor and extruding drum, reduce the complexity of system, reduced equipment investment and later maintenance; Meanwhile, the utility model adopts air pressure direct extruding gasbag outer fluid, can be in very broad pressure range pumping fluid efficiently.
2, good reliability, use safety, be suitable for large-scale promotion application.In the utility model, adopted air bag and pressure controlled valve to control the pressure of fluid, cancelled mechanical extruding, therefore, with respect to the easy fatigue failure of rubber pipe of existing peristaltic extrusion pump, reliability is higher.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: fluid tank 1, air bag 2, fluid inlet 3, fluid output 4, one-way valve 5, gas charging valve 6, pressure controlled valve 7, admission line 8, exhaust duct 9.
Embodiment
Below in conjunction with accompanying drawing explanation and embodiment, the utility model is described in further detail.
Referring to Fig. 1, a kind of internal airbag formula fluid extruding device, comprises fluid tank 1, is provided with fluid inlet 3 and fluid output 4 in described fluid tank 1, and general fluid import 3 is arranged on the top of fluid tank 1, and fluid output 4 is arranged on the bottom of fluid tank 1; On described fluid output 4, be provided with one-way valve 5, one-way valve 5 herein can prevent fluid suck-back and leakage.In described fluid tank 1, be provided with air bag 2, on described air bag 2, be provided with the admission line 8 being connected with the pipeline of gas pressure source and the exhaust duct 9 being connected with atmosphere, on described exhaust duct 9, be provided with pressure controlled valve 7, pressure controlled valve 7 is arranged on the exhaust duct 9 outside fluid tank 1; Pressure controlled valve 7 is generally one-way valve, pressure controlled valve 7 has safety valve and two effects of release, can control gas pressure in air bag 2, guarantee that air bag 2 obtains the pressure needing, in the time that the fluid consuming in fluid tank 1 is complete, pressure controlled valve 7 is controlled the gas of discharging in air bag 2 and is filled with fluid to facilitate again to fluid tank 1.Gas pressure source can be high-pressure gas cylinder, and such as high-pressure nitrogen bottle, high pressure air bottle etc. can be also the subsidiary compressed gas system of various devices or factory, can also utilize original air compressor and gas holder as gas pressure source.Described fluid tank 1 is pressure resistant vessel, can be designed to bear different pressures in reality; Air bag 2 can be made with rubber, also can adopt artificial synthetic thin-film material to make, fluid tank 1 and air bag 2 also can be designed to different shapes according to actual needs, air bag 2 design should with fluid tank 1 shape match consistent, the fluid in fluid tank 1 can be drained.Preferably, on described admission line 8, be provided with gas charging valve 6, gas charging valve 6 is arranged on the admission line 8 outside fluid tank 1, and in real work, admission line 8 can share with exhaust duct 9 part being connected with air bag 2; Gas charging valve 6 is generally one-way valve, and gas charging valve 6 is controlled gas pressure source and be filled with to air bag 2 amount of gas, guarantees air bag 2 inflation pressures.Preferably, on described fluid inlet 3, be provided with one-way valve 5, one-way valve 5 can prevent the liquid backflow in fluid tank 1.
When work, first the gas charging valve 6 on air bag 2 is closed, the pressure controlled valve 7 on exhaust duct 9 is opened, and annotates after fluid to fluid tank 1 by fluid inlet 3, discharges the interior gas of air bag 2 thereby air bag 2 shrinks; Then fluid inlet 3 is closed, thereby the gas charging valve 6 of opening on admission line 8 makes gas pressure source input pressurized gas to air bag 2, air bag 2 be inflated, and then convection cell tank 1 inner fluid carries out supercharging; In the time that the work of this squeezing unit is outwards carried fluid, because fluid expulsion, air bag 2 expansion fill fluids are discharged space, therefore air bag 2 pressure decreaseds, gas pressure source can supplement pressurized gas to air bag 2 timely, so that maintain the force value that real work needs in fluid tank 1; In the time that air bag 2 is full of fluid tank 1 completely, now in fluid tank 1, fluid drains, and opens pressure controlled valve 7, discharges gas in air bag 2, and then to fluid tank 1 fluid of again annotating; After in fluid tank 1, fluid is filled it up with, closing pressure control valve 7, and carry out supercharging to air bag 2 inflating pressures with the fluid in convection cell tank 1 again by gas charging valve 6, so periodic duty.
In now a lot of factories or equipment, often can be accompanied with the gas pressure source such as pressurized air or Ignitable gas devices; the utility model utilization utilizes existing gas pressure source to air bag 2 pressurisings; the pressure of fluid tank 1 is controlled by gas charging valve 6 and pressure controlled valve 7; regulate fluid pressure in fluid tank 1 by be filled with or discharge a part of gas in air bag 2; fluid in the air bag 2 extrusion fluid tanks 1 of pressurising, thus discharge the fluid in fluid tank 1.In practical application, the novel pressurized gas that utilizes of this use is realized pressurized delivered to the material such as various slurries and liquid of food and medicine industry, can not produce any pollution to material; This use is novel also can be for technological process industry such as chemical industry and medicine, to some chemical substances in technological process and chemical reagent supercharging; The utility model can also be made little pump, can, for the high-lift special occasions of small-power, carry strong acid, highly basic, and other liquid or slurry state chemical substances.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, said structure all should be considered as belonging to protection domain of the present utility model.
