Use the utility model discloses a glass autoclave vacuum apparatus is through controller control automatic control valve's switching to prevent that the PVB among the laminated glass from being taken out. Simultaneously, when high -pressure gas got into the vacuum line, ability self -closing automatic control valve prevented the appearance of equipment damage and potential safety hazard.
Description
Technical field
The utility model relates to glass post-processing technical field, particularly the glass autoclave vacuum unit that is drawn out of of a kind of PVB of preventing.
Background technology
PVB laminated glass has been widely used in the association areas such as automobile, building, security as shatter proof glass.Current suitability for industrialized production PVB laminated glass generally adopts dry process, be placed between two-layer or multiple glazing, then hot pressing forms in autoclave by PVB film.Specifically, glass PE nylon membrane is packed, load onto valve, tracheae, edge sealing is made vacuum bag and is placed in autoclave, PE nylon membrane internal duct is communicated with vacuum pump, when high pressure temperature in the kettle reaches 120 DEG C ~ 140 DEG C and pressure reaches 1.1MPa ~ 1.4Mpa, start vacuum pump, PE nylon membrane forms negative pressure, and the outside malleation having 1.1MPa ~ 1.4Mpa that maintains, thus hot press operation is carried out to PVB laminated glass.
In prior art vacuum-lines connection or close generally come by pulling vacuum control valve manually, due to human factor, closedown vacuum control valve poor timing, cause the PVB in laminated glass to be often drawn out of, and then bring loss to production.In addition, in production process, the reason such as poorly sealed, valve gas leakage of PE nylon membrane can cause high pressure gas to enter vacuum-lines, thus causes the damage of vacuum pump, more there is certain potential safety hazard.
In sum, be necessary to develop a kind of glass autoclave vacuum unit, to solve the problem.
Utility model content
In view of this, the utility model provides a kind of glass autoclave vacuum unit, and after vacuumizing and reaching specific time, vacuum control valve cuts out automatically, thus the situation preventing PVB to be drawn out of occurs.Meanwhile, when high pressure gas enter vacuum-lines, automatically can close vacuum control valve, and remind operator to take corresponding measure in time.
The utility model is solved the problem by following technique means:
The utility model provides a kind of glass autoclave vacuum unit, comprise autoclave and vacuum pump, connected by vacuum-lines between described autoclave and vacuum pump, vacuum-lines is provided with manually operated control valve, also comprise automatically controlled valve, controller, temperature sensor and pressure transmitter, described automatically controlled valve and manually operated control valve are arranged in parallel on vacuum-lines, described controller is electrically connected with vacuum pump, automatically controlled valve, temperature sensor and pressure transmitter respectively, and described temperature sensor and pressure transmitter are arranged on autoclave.
Further, also comprise the under meter be arranged on vacuum-lines, described under meter is connected with controller.
Further, also comprise a warning howler, described warning howler is connected with controller.
Further, described automatically controlled valve is magnetic valve or motorized valve.
Further, described controller is PLC.
The beneficial effects of the utility model: the utility model provides a kind of glass autoclave vacuum unit, comprise autoclave and vacuum pump, connected by vacuum-lines between described autoclave and vacuum pump, vacuum-lines is provided with manually operated control valve, also comprise automatically controlled valve, controller, temperature sensor and pressure transmitter, described automatically controlled valve and manually operated control valve are arranged in parallel on vacuum-lines, described controller respectively with vacuum pump, automatically controlled valve, temperature sensor and pressure transmitter electrical connection, described temperature sensor and pressure transmitter are arranged on autoclave.Use glass autoclave vacuum unit of the present utility model, controlled the opening and closing of automatically controlled valve by controller, thus prevent the PVB in laminated glass to be drawn out of.Meanwhile, when high pressure gas enter vacuum-lines, automatically can close automatically controlled valve, prevent the appearance of structure deteriorate and potential safety hazard.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1, a kind of glass autoclave vacuum unit of the present utility model, comprise autoclave 1 and vacuum pump 2, connected by vacuum-lines 3 between described autoclave 1 and vacuum pump 2, vacuum-lines 3 is provided with manually operated control valve 4, also comprise automatically controlled valve 5, controller 6, temperature sensor 7 and pressure transmitter 8, described automatically controlled valve 5 is arranged in parallel on vacuum-lines 3 with manually operated control valve 4, described controller 6 respectively with vacuum pump 2, automatically controlled valve 5, temperature sensor 7 and pressure transmitter 8 are electrically connected, described temperature sensor 7 and pressure transmitter 8 are arranged on autoclave 1.Generally also vacuum tank is provided with, for providing stable vacuum pressure to device between autoclave 1 and vacuum pump 2.Described manually operated control valve 4 is generally ball valve, described automatically controlled valve 5 by circuit cut-out and close the opening and closing realizing valve.Automatically controlled valve 5 and manually operated control valve 4 are arranged in parallel, when having a power failure, automatically controlled valve can not work, or the temperature and pressure signal that receives of controller 6 is when having an error, cause controller 6 normally can not control automatically controlled valve 5 to open, thus vacuum-lines 3 can be cut off by pulling manually operated control valve 4 manually.
Concrete workflow is: when temperature sensor 7 detect high pressure temperature in the kettle reach 120 DEG C ~ 140 DEG C and pressure transmitter 8 detect that pressure reaches 1.1MPa ~ 1.4Mpa time, the circuit of automatic vacuum pump 2 and automatically controlled valve 5 connected by controller 6, automatically controlled valve 5 is opened, and vacuum pump 2 starts simultaneously.After vacuumizing the time reaching setting, controller 6 disconnects the power supply of vacuum pump 2 and automatically controlled valve 5 again.
As the further improvement of such scheme, also comprise the under meter 9 be arranged on vacuum-lines 3, preferably under meter 9 is arranged on main line, and under meter 9 is electrically connected with controller 6.When PE nylon membrane is poorly sealed, valve gas leakage or PE film by thermogenesis breach time, high-pressure air enters inside vacuum-lines 3, and the gas flowing through under meter 9 can increase sharply, and when exceeding the flux values that controller 6 sets, automatically controlled valve 5 cuts out.Thus prevent the appearance of structure deteriorate and potential safety hazard.
As the further improvement of such scheme, also comprise a warning howler 10, described warning howler 10 is electrically connected with controller 6.When above-mentioned leakage situation occurs, controller 6 can connect the circuit of warning howler 10, thus reminds operator to take corresponding measure.
As the further improvement of such scheme, described automatically controlled valve 5 is magnetic valve or motorized valve.Magnetic valve or motorized valve are conventional control valve, and low price is easy to use.
As the further improvement of such scheme, described controller 6 is PLC.PLC good reliability, convenient application.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
