Background technology:
At present in of the adjustment and manner of execution of perfusion industry to the pressure of liquid medium or liquid-solid mixing medium, the requirements of adopting the level pressure power or adopt gas medium directly to apply pressure to the outlet pressure that makes liquid medium in the liquid medium container to meet cast more, when pressure need be adjusted, need carry out supercharging or decompression to the pressure of entire container. but its shortcoming is easily gas directly to be discharged outlet when the medium in the container has used up or approached to use up, be not easy to the gas-liquid splash occur in the process of the sealing of liquid medium or cast, general adopt reserved the material that pours into more, avoids medium and applying pressurised gas to spray outlet simultaneously.Waste and the defective of formed product and the inconvenience in the operation of material have been caused.
Summary of the invention:
The utility model purpose is to overcome above-mentioned shortcoming, provide a kind of simple in structure, the automatic pressure compensation arrangement of easy to operate preset pressure, it adopts indirect pressurization technology, not only solved in the process of the sealing of liquid medium or liquid-solid mixing medium or cast and this problem of gas-liquid splash occurred, also avoided easy the fusing of gas medium and liquid medium, more can be applied to vacuum-formed perfusion or perfusion under the pressure condition atmosphere is arranged, by adjusting and setting, realize the automatic adjustment of outlet pressure medium is meanwhile controlled simultaneously to the different pressure regulator valves of moulding pressure.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
The automatic pressure compensation arrangement of preset pressure, described pressure compensator comprises connection in turn: gas input device, pressure-regulating device, pressure converting means and liquid input device, described pressure converting means comprises the pressure conversion chamber that is communicated with liquid input device, pressure actuated device that is connected with pressure conversion chamber and the position sensor that cooperates with pressure actuated device, pressure actuated device connects pressure-regulating device.
Described gas input device comprises: the air pump that is connected with compressed gas source, and air pump connects intake valve, and intake valve connects gas storage tanks, and gas storage tanks connects pressure-regulating device, cooperates in addition with described gas storage tanks to be provided with Pressure gauge and vent valve.
Described pressure-regulating device comprises one or more groups and the magnetic valve that cooperatively interacts and the pressure regulator valve that connect.
Pressure actuated device in the described pressure converting means is for driving cylinder.
Pressure conversion chamber in the described pressure converting means is a cylinder body, is provided with ceramic chamber lining in it, cooperates with ceramic chamber lining to be provided with Ceramic piston and to move in cylinder body.
Described liquid input device comprises that import, the control valve that is connected with import, control valve are communicated with pressure conversion chamber, reach the liquid outlet that is communicated with pressure conversion chamber in addition.
Adopt technique scheme, the utility model is simple in structure, easy to operate, the pressurization technology that it is indirect, not only solved in the process of the sealing of liquid medium or liquid-solid mixing medium or cast and this problem of gas-liquid splash occurred, also avoided easy fused of gas medium and liquid medium, more can be applied to vacuum-formed perfusion or perfusion under the pressure condition atmosphere is arranged.By adjusting and setting, realize the automatic adjustment of outlet pressure medium is meanwhile controlled simultaneously to the different pressure regulator valves of moulding pressure.
Description of drawings:
Below with accompanying drawing the utility model is described in detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model pressure conversion cell structure schematic diagram.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is described in detail:
Embodiment of the present utility model as shown in Figure 1, the automatic pressure compensation arrangement of preset pressure, described pressure compensator comprise connection in turn:
Pressure-regulating device 2; Comprise one or more groups and the magnetic valve that cooperatively interacts 21 and the pressure regulator valve 22 that connect.
Pressure converting means 3; Comprise the pressure conversion chamber 31 that is communicated with liquid input device 4, pressure actuated device 32 that is connected with pressure conversion chamber and the position sensor 321,322 that cooperates with pressure actuated device 32, pressure actuated device 32 connects pressure-regulating device 2.Pressure actuated device 32 in the described pressure converting means 3 can be and drives cylinder or hydraulic cylinder or other drive unit.Described pressure conversion chamber 31 is a cylinder body, is provided with ceramic chamber lining 311 in it, cooperates with ceramic chamber lining 311 to be provided with Ceramic piston 312 and to move in cylinder body.
During work, because pressure conversion chamber 31 of the utility model design, make it that variation of volume can take place under the effect of external force cylinder, can realize simultaneously sealing to liquid medium or liquid-solid mixing medium, when position sensor 321,322 inductions, liquid medium enters by import 41, the valve of opening 42, medium has entered and has utilized the pressure conversion chamber 31 that drives cylinder 32 actions and Volume Changes takes place, when pressure medium very big but export the pressure at 19 places when very little medium directly flowed to outlet 19, when increasing to resistance greater than pressure conversion chamber 31 (resistance of the pressure by preset element 22 and the switch adjustable pressure conversion chamber 31 of selection element 21) with the pressure of outside container that is connected or pipeline when outlet 19 places, liquid medium promotes pressure conversion chamber 31 and volume-variation takes place until position sensor 321 in by outlet 41,322 have an effect, at this moment valve 42 is closed, when the pressure at outlet 43 places descends, valve because of 22 is selected and the relation of the pressure regulation between 21, pressure conversion chamber 31 is under the effect of propulsive thrust, release through exporting 43 and flow out being stored in liquid medium in the pressure conversion chamber 31, and the pressure of outlet all the time with the causality that fits in of element 21 and 22.
The beneficial effects of the utility model: the predeterminable different periods of pressure of outlet liquid medium or liquid-solid mixing medium pressure are carried out different Output pressures and pressurize, under atmospheric condition, the medium that can guarantee to be accepted in the container of medium is full, does not have bubble or weak breath bubble. under vacuum state, can guarantee medium be shaped after no air blister defect.
Another place's characteristics of the present utility model are pressure conversion chamber 31, and the structure of pressure conversion chamber adopts the clearance seal of ceramic structure. Pottery has self-lubricating property, long service life, and activity is freer, to being quick on the draw of pressure, avoided adopting the resistance significant change of flexible barrier material generations when easily wearing and tearing taking place such as O type circle or leaking, guaranteed to have prolonged service life by the stable of operation pressure.
Another characteristics of the present utility model are: on pressure is regulated, also because of adopt cylinder make the adjusting of pressure become simple (because of the more whole magazine of the gas-storing capacity of cylinder little).
