Description
Technical field
The utility model relates to a kind of heparin tube vacuum degree control device.
Background technology
At present, the important technical index of medical vacuum heparin tube one is the accurate precision of degree of vacuum, factory is when producing heparin tube and vacuumizing, the Survey control mode of degree of vacuum measures and set degree of vacuum in required seal closure by degree of vacuum instrument, when vacuum instrumentation detects that in seal closure, degree of vacuum reaches instrument setting value, instrument sends on-off signal, closedown vacuumizes electromagnetic valve, be energized to tamponade cylinder, tamponade cylinder is about to vacuum lamp seal rubber plug press-in test tube, ensure in vitro degree of vacuum, after this on-off signal provides, be not pressed into the degree of vacuum of inhaling in plug front 2 ~ 5 second time inner seal cover can because of poorly sealed leakage, exhaust solenoid valve is not closed completely leakage, tamponade cylinder is pressed speed inconsistent when barometric fluctuation, degree of vacuum in seal closure is caused to change, make the degree of vacuum that in heparin tube, degree of vacuum and setting need that serious error occur, have a strong impact on heparin tube quality, make large-tonnage product cannot reach design objective generation quality problems because of degree of vacuum.
Utility model content
Technical problem to be solved in the utility model is, provides one to guarantee heparin tube degree of vacuum precision, improves the heparin tube vacuum degree control device of heparin tube quality.
The utility model solves the technical scheme that its technical matters adopts: a kind of heparin tube vacuum degree control device, comprises vacuum lamp seal rubber plug, test tube, seal closure, tamponade plate, tamponade cylinder, exhaust solenoid valve, vacuumizes electromagnetic valve, degree of vacuum control cock, vacuum pump, vacuum sensor and controller; Described vacuum lamp seal rubber plug is arranged on seal closure inside top, and described test tube is arranged on tamponade plate, and is positioned at immediately below vacuum lamp seal rubber plug, and described tamponade plate is connected with seal closure, and described tamponade cylinder is connected with tamponade plate; Described seal closure by pipeline respectively with exhaust solenoid valve, vacuumize electromagnetic valve and be connected, described exhaust solenoid valve is connected with controller, the described electromagnetic valve that vacuumizes is connected with degree of vacuum control cock, vacuum pump, controller, and described degree of vacuum control cock is connected with seal closure, controller; Described vacuum sensor is positioned at seal closure, and is connected with controller.
Further, described controller is PLC.
Working process: when vacuum pump work, exhaust solenoid valve energising is closed, vacuumize electromagnetic valve to open, vacuumize in seal closure, vacuum sensor converts the vacuum degree detected to electric signal and is delivered to controller, controller carrys out the stable of degree of vacuum in adjustment seal closure according to the vacuum degree control degree of vacuum control cock producing setting, before vacuum lamp seal rubber plug is not pressed into test tube, keep this from motion tracking adjustment state always, when this stabilized conditions reach setting require time, tamponade cylinder is up, by vacuum lamp seal rubber plug press-in test tube.
Utilize the utility model to control, in vacuum lamp, degree of vacuum precision can be fully guaranteed, thus guarantees the quality of vacuum lamp.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to accompanying drawing, the present embodiment comprises vacuum lamp seal rubber plug 1, test tube 2, seal closure 3, tamponade plate 4, tamponade cylinder 5, exhaust solenoid valve 6, vacuumizes electromagnetic valve 7, degree of vacuum control cock 8, vacuum pump 9, vacuum sensor 10 and controller 11; Described vacuum lamp seal rubber plug 1 is arranged on seal closure 3 inside top, and described test tube 2 is arranged on tamponade plate 4, and is positioned at immediately below vacuum lamp seal rubber plug 1, and described tamponade plate 4 is connected with seal closure 3, and described tamponade cylinder 5 is connected with tamponade plate 4; Described seal closure 3 by pipeline respectively with exhaust solenoid valve 6, vacuumize electromagnetic valve 7 and be connected, described exhaust solenoid valve 6 is connected with controller 11, the described electromagnetic valve 7 that vacuumizes is connected with degree of vacuum control cock 8, vacuum pump 9, controller 11, and described degree of vacuum control cock 8 is connected with seal closure 3, controller 11; Described vacuum sensor 10 is positioned at seal closure 3, and is connected with controller 11.
In the present embodiment, described controller is PLC.
Working process: when vacuum pump 9 works, exhaust solenoid valve 6 is energized and closes, vacuumize electromagnetic valve 7 to open, vacuumize in seal closure 3, vacuum sensor 10 converts the vacuum degree detected to electric signal and is delivered to controller 11, controller 11 carrys out the stable of degree of vacuum in adjustment seal closure 3 according to the vacuum degree control degree of vacuum control cock 8 producing setting, before vacuum lamp seal rubber plug 1 is not pressed into test tube 2, keep this from motion tracking adjustment state always, when this stabilized conditions reach setting require time, tamponade cylinder 5 is up, vacuum lamp seal rubber plug 1 is pressed into test tube 2, .
Utilize the utility model to control, in vacuum lamp, degree of vacuum precision can be fully guaranteed, thus guarantees the quality of vacuum lamp.
