Description
Technical field
The utility model relates to the filling pump on the drug filling machine, especially relates to the two-way high technology ceramics pump of a kind of self energy.
Background technique
At home in the pharmacy producer, the employed drug filling machine of medicament metering and bottling, its filling pump mostly is the glass plunger pump, and the working principle of glass plunger pump is: it has an outlet valve above pump housing, one inlet valve is arranged below, by the switch control liquid medicine turnover of two valves.The validity of glass pump is not high, measures inaccurately, and error reaches 4 percent.And it is exactly easy to wear that the glass plunger pump has the weakness of a maximum, and consequent chips of glass can enter in the medicine bottle with liquid medicine, and causes the medicine disqualification rate, and people's life health is brought threat.
At present, the domestic pharmacy of minority producer from external import some ceramics pole stopper pumps, the plunger of these ceramics pole stopper pumps be the pottery, not easy to wear, do not produce any dregs during work.And ceramics pole stopper pump has been abandoned the outmoded turnover water valve of glass plunger pump, directly utilize to turn to bibcock to control the liquid medicine import and export, so accurate measurement, error is little.Yet, the shortcoming of a maximum of above-mentioned ceramic plunger pump is: turn to the commutation of bibcock just can carry out by changement, if on common drug filling machine, use, just need to increase new and the synchronous automatic reversing mechanism of can action, thereby user cost is higher.
Summary of the invention
The utility model mainly solve existing glass plunger pump medicament filling measurement inaccurate, not wear-resistant, easily produce chips of glass; The ceramic plunger pump can't normal use at common drug filling machine, user cost high-technology problem.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopted is: it comprises the pump housing, be provided with the ceramics pole plug cylinder in the pump housing, be combined with the ceramics pole stopper in the plunger case, the water outlet place of the described pump housing is provided with the outlet valve pipe of nose end sealing, the tube wall of this outlet valve pipe is provided with osculum, outside the outlet valve pipe, be with and go out gelatine sleeve what osculum blocked, be provided with the inlet valve pipe in the water intake of the described pump housing, this inlet valve pipe is with the water inlet gum cover that its mouth of pipe is covered outward, has square hole on the sidewall of water inlet gum cover.
As preferably, the sealing of an end running-on of described water inlet gum cover.
The utlity model has easy to install and use, service precision height, characteristics such as wear-resisting.Quality of fit height between ceramic plunger and the ceramics pole plug cylinder, wear resistance is good.It promptly goes up i.e. usefulness, do not need filling machine is additionally transformed, and medicament can error rate only is 4/1000ths, and the utility model also efficiently solves problems such as the glass plunger pump is not wear-resistant.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A shown in Figure 1 place partial enlarged drawing;
Fig. 3 is a B shown in Figure 1 place partial enlarged drawing.
Embodiment
Fig. 1 is a structural representation of the present utility model, and it comprises a metal pump housing 3, and the pump housing 3 front ends are provided with water inlet tap 7, water outlet 10; The pump housing 3 internal fixation have ceramics pole plug cylinder 2, are combined with ceramics pole stopper 1 in the plunger case, and therefore the quality of fit height of ceramics pole stopper 1 and ceramics pole plug cylinder 2 can not produce liquid medicine seepage phenomenon.Be provided with water intake 41 and water outlet 42 on the pump housing 3 under water inlet tap 7, water outlet 10 bases, the cavity 4 of water intake 41 and water outlet 42 and ceramics pole plug cylinder 2 is connected, and described ceramics pole stopper 1 can move back and forth in the cavity of plunger case 2.
By Fig. 2 further as can be known, water inlet gum cover 5 one end running-ons are closed end 52, and the other end running-on is opened and is enclosed within on the water valve pipe 6.The water inlet gum cover can adopt the medical latex material, its head have tighten the circle 51, this tightens snare 51 and is embedded in inlet valve pipe 6 upper grooves 61, can prevent out that gelatine sleeve 5 comes off.Intake closed end 52 sealing of gum cover 5 of the inlet valve pipe 6 bottom mouths of pipe.During work, liquid medicine can only enter in the inlet valve pipe 6 from the square hole 53 that goes out on gelatine sleeve 5 jacket walls.Screw thread is arranged at the bottom of water inlet tap 8 bases, can directly be screwed on the pump housing 3, and outlet valve pipe 6 is pressed in the water intake 41, and when intaking like this, water inlet tap 7 forms connected relation mutually with inlet valve pipe 6.
By Fig. 3 further as can be known, outlet valve pipe 8 is arranged on the water outlet place of the pump housing and is integrated with the pump housing 3, and the outlet valve pipe 8 front end mouths of pipe seal, and are provided with water outlet 81 on its tube wall.Be with out gelatine sleeve 9 on outlet valve pipe 8, this goes out gelatine sleeve and adopts the medical latex material equally; Go out gelatine sleeve 9 for the front end and back end connect tubular, its head has and tightens circle 91, this tightens circle 91 and is enclosed within outlet valve pipe 8 upper grooves 82, can prevent out that gelatine sleeve comes off.Screw thread is arranged at the base bottom of water outlet 10, can be screwed on the pump housing 3 at outlet valve pipe place, and the base internal diameter of water outlet 10 can surround the outlet valve pipe 8 that is with out gelatine sleeve 9 fully greater than the water valve external diameter of pipe, during water outlet, water outlet 10 forms connected relations with outlet valve pipe 8 like this.
When ceramics pole stopper 1 outwards spurred, the pressure in the ceramics pole plug cylinder cavity 4 reduced.Because the effect of atmospheric pressure, extraneous liquid medicine can only enter from water inlet tap 7.When liquid medicine is in water inlet tap 7 enters into inlet valve pipe 6, because the pressure that current bring and the effect of atmospheric pressure, make that the water inlet rubber finger sleeve 5 on the sealed feed valve pipe 6 is washed open, so liquid medicine flows in the plunger case cavity 4 by the square hole 53 above the water inlet rubber finger sleeve 5.The appointment that upwards is stretched to the liquid medicine capacity when ceramics pole stopper 1 stops when requiring, so inlet valve pipe 6 liquid medicine stop to flow into.When 1 beginning of ceramics pole stopper advances inward, ceramics pole stopper 1 compression liquid medicine, the liquid medicine that pump housing cavity is 4 li also is forced outwardly and squeezes, the closed end of the water inlet gum cover 5 on the inlet valve pipe 6 is because the effect of hydraulic pressure is attached to the mouth of pipe place of inlet valve pipe 6 closely, the mouth of pipe of inlet valve pipe 6 is blocked, so liquid medicine stream is not gone out.And under the effect of hydraulic pressure, the gelatine sleeve 9 that goes out that covers water outlet 81 is washed open fully, so the just continuous osculum 81 from outlet valve pipe 8 of liquid medicine flows out.
Like this, when ceramics pole stopper 1 was pulled outwardly, liquid medicine just flowed in the pump housing cavity 4 from inlet valve pipe 6, and when ceramics pole stopper 1 inwardly compressed, liquid medicine only flowed out from water outlet 10.And so forth, just can constantly carry out can to medicine bottle.Certainly, inlet valve pipe 6 can exchange with the position of outlet valve pipe 8 on valve body, and its running principle is identical.
