The utility model has a simple structure, convenient pressure regulating and big regulating range, meets the tanking (tank-filling) requirements of liquid medicines, can rapidly compensate the pressure loss of tanked liquids, and the tanking pressure is stable, tanking exact, also help enhance the tanking speed an production efficiency, can be widely applied onto the tanking equipments of large infusion class of medicines and foods of similar kind or other industries.
Description
Technical field
The utility model relates to a kind of pressure balancing tank, is used for the accurate can of soup.
Background technology
The bulking system of transfusion similar drug, generally adopt an elevated tank to store buffering liquid medicine, the pressure when stablizing liquid medicine filling, elevated tank generally need be placed on the height of 5-15 rice, fluid pressure can only be controlled at below the 1bar, improves pressure if desired, then can only be by improving the height of elevated tank, Operation and Maintenance gets up and very bothers, it is big to take up room, and filling speed is slow, and production efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of pressure balancing tank simple in structure, and pressure is easy to adjust, satisfies the can requirement of soup, is beneficial to the raising filling speed, enhances productivity.
Pressure balancing tank described in the utility model has a buffering diaphragm that tank inner chamber is divided into top air chamber and following fluid chamber, is provided with inlet and liquid outlet in the fluid chamber, is provided with porting in the air chamber, and porting is provided with air valve.
During use, adjust the pressure of the filling liquid in the fluid chamber by the air pressure in the control gaseous chamber, pressure control is convenient, and setting range is big, and comformability is strong.
If pass the diaphragm position showing rod of air chamber, the following end in contact of diaphragm position showing rod is on the buffering diaphragm.By observing the position of diaphragm position showing rod, learn the position of buffering diaphragm, thereby can know the pressure of liquid drug.
With the corresponding position-detection sensor of establishing of the upper end position of diaphragm position showing rod, can detect the position of diaphragm position showing rod automatically, thereby the air valve on the porting can be designed to cooresponding electric-air valve, carry out automatic guidance according to the detected position signal of detecting sensor.
The diaphragm position showing rod of air chamber outside is encapsulated in the transparent protection pipe box, protects diaphragm position showing rod, guarantee dependable performance.
On air chamber, connect compression indicator, can directly indicate the air pressure in the air chamber.
Principle of work:
The liquid pump is transported to fluid chamber to soup with constant speed, and when fluid pressure during greater than the epicoele gaseous tension, diaphragm position showing rod is up, detecting sensor is sent signal when reaching certain position, air valve is opened automatically, gives the air chamber tonifying Qi, and air chamber pressure increases.After the air chamber gaseous tension increased to greater than fluid pressure, diaphragm was descending, and the air chamber volume increases, and gaseous tension reduces, and when being reduced to cavity of resorption fluid pressure balance, the buffering diaphragm stops at midway location.Because volume is enough big, when can begins, fluid chamber liquid reduces, the buffering diaphragm moves down, but pan position is very little down, and the air chamber volume increases, but increase is very little, so the air chamber gas pressure change is very little, the pressure of air chamber equals the pressure of fluid chamber, so the variation of the pressure of fluid chamber is also very little.After can stops, replenishing soup by the liquid pump, the buffering diaphragm comes back to the intermediate equilibria position.Thereby work as filling valve in the process that opens or closes, the pressure of soup delivery port can be stabilized in certain scope, by regulating air valve and liquid pump speed, can adjust the soup delivery pressure of fluid chamber.End at the can pipeline increases with refluxing opening, can improve the stability of delivery pressure biglyyer, also can play a protective role to the liquid pump simultaneously.
The utility model pressure balancing tank, simple in structure, pressure is easy to adjust, and setting range is big, satisfies the can requirement of soup, can fast speed the loss of pressure of compensation filling liquid, filling pressure is stable, can is accurate, is beneficial to again to improve filling speed and production efficiency, can be widely used on the filling apparatus of infusion solutions similar drug and food similarly or other industry.
Description of drawings
Fig. 1, the utility model one example structure scheme drawing.
Among the figure: 1, liquid outlet 2, fluid chamber 3, buffering diaphragm 4, inlet 5, air chamber 6, diaphragm position showing rod 7, link span 8, switch bracket 9, porting 10, compression indicator 11, detecting sensor 12, transparent protection pipe box.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, pressure balancing tank described in the utility model, clamp buffering diaphragm 3 by the interconnective lower tank of going up, buffering diaphragm 3 is divided into top air chamber 5 and following fluid chamber 2 with tank inner chamber, be provided with inlet 4 and liquid outlet 1 in the fluid chamber 2, be provided with porting 9 in the air chamber 5, porting is provided with air valve, the diaphragm position showing rod 6 that air chamber of passing 5 is arranged, the following end in contact of diaphragm position showing rod 6 is on buffering diaphragm 3, the corresponding position-detection sensor 11 that is provided with the upper end position of diaphragm position showing rod 6, by link span 7 and switch bracket 8 that detecting sensor 11 is fixing, the diaphragm position showing rod 6 of air chamber 5 outsides is encapsulated in the transparent protection pipe box 12, is connected with compression indicator 10 on the air chamber 5.
During work, soup enters fluid chamber 2 by the liquid pump by inlet 4, flows into container filling by liquid outlet 1, and clean compressed air enters air chamber 5 by porting 9.When fluid pressure during greater than the gaseous tension in the air chamber 5, diaphragm position showing rod 6 is up under the drive of buffering diaphragm 3, sends signal by detecting sensor 11 when reaching desired location, and electric-air valve is opened, give air chamber 5 tonifying Qi by porting 9, pressure increases.After the gaseous tension in the air chamber 5 increases to greater than the fluid pressure in the fluid chamber 2, diaphragm position showing rod 6 is descending under the drive of buffering diaphragm 3, air chamber 5 volumes increase, gaseous tension reduces, when be reduced to fluid chamber 2 in during the fluid pressure balance, buffering diaphragm 3 stops at midway location, changes according to pressure like this and adjusts, and makes the pressure stability of liquid outlet 1 in certain scope.
