Description
Technical field
The utility model relates to a kind of technology and device that the pressurized gas bulking system is used for system is vacuumized the device safety protections such as vacuum pump of processing that be used for.Specifically, this device is used for the safety protection device to vacuum flush system under the gas filling system mesohigh state, belongs to the pressurized gas field and is used for the security protection technology field that the pressurized gas bulking system vacuumizes processing.
Background technique
In pressurized gas was produced, bottled gas accounted for greatly, and the can of bottled gas relates to the processing of gas cylinder, and the displacement cleaning of bulking system pipeline etc. all will be used vacuum system.Simultaneously in the bulking system of electronic gas such as ammonia, silane; Then relate to the quality of can safety and product, if the gas cylinder inter-process is bad, air is taken out unclean; Bulking system leaves air; Certainly will cause the oxidation even the spontaneous combustion of silane, gently then influence product-filled quality, heavy then cause production safety accidents such as silicone hydride combustion blast.System is vacuumized processing, is the displacement process for treating of system and gas cylinder the most efficiently and effectively.
At present; To the protection of vacuum pump, mainly be after closing vacuum pump, flow backwards to bulking system for preventing pumping fluid; The electromagnetism band vacuum gas filling valves that adopt are controlled more, do not backflow and the problem of contaminated system but this method can only solve the vacuum system final vacuum pump oil that quits work.Can not solve under high pressure conditions owing to the security incident that vacuum valve causes vacuum pump oil spout, product spontaneous combustion blast etc. to cause is opened in operator's misoperation, cause the problem of personal injury and property loss.
The model utility content
The utility model technical problem to be solved is to overcome the defective that existing technology exists, and provides a kind of pressurized gas bulking system to vacuumize the protective gear with vacuum system, is used to protect the safety that the pressurized gas bulking system is vacuumized the vacuum system of usefulness.
The utility model in order to realize the technological scheme that the model utility purpose is adopted is: the pressurized gas bulking system vacuumizes the protective gear with vacuum system, comprises pressure transducer, PLC control module, hand switch valve, pneumatic on-off valve, two-position three way magnetic valve, driving gas source of the gas; It is characterized in that: the electrical signal of pressure transducer exports the PLC control module to, and PLC control module control two-position three way magnetic valve opens and closes; Hand switch valve and pneumatic on-off valve are connected on the same pipeline; The intake interface of two-position three way magnetic valve connects and drives the gas source of the gas, and the interface of giving vent to anger of two-position three way magnetic valve is connected with the driving gas interface of pneumatic on-off valve, and another of two-position three way magnetic valve interface of giving vent to anger is used to drive gas emptying.
The utility model is employed in the pressurized gas bulking system and installs pressure transducer additional; Through the PLC control module signal of pressure transducer is handled; When pressure signal is higher than solenoid valve value of opening that the PLC control module is set; The PLC control module is exported out code to electromagnetic valve switch, and pneumatic on-off valve is in closed condition all the time, and pressurized gas bulking system and vacuum flush system are in off state.The force value that detects pressure transducer when the PLC control module is lower than solenoid valve value of opening that the PLC control module is set; The PLC control module is exported OPEN to electromagnetic valve switch; Pneumatic on-off valve is opened, and pressurized gas bulking system and vacuum flush system are in UNICOM's state.Therefore, when the pressurized gas bulking system was in high pressure conditions, even misoperation hand switch valve, pressurized gas bulking system and vacuum flush system can UNICOMs yet, thereby reach the safety protection purpose to vacuum system.
Description of drawings
Fig. 1 is that the utility model pressurized gas bulking system vacuumizes the protective gear structural representation with vacuum system.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
As shown in Figure 1; The pressurized gas bulking system vacuumizes the protective gear with vacuum system, comprises pressure transducer 4, PLC control module, hand switch valve (membrane valve) 5, pneumatic on-off valve (high pressure Bellows valves) 6, two-position three way magnetic valve, driving gas source of the gas.The electrical signal of pressure transducer exports the PLC control module to, and the relay switch of PLC control module links to each other with two-position three way magnetic valve, and PLC control module control two-position three way magnetic valve opens and closes.Hand switch valve and pneumatic on-off valve are connected on the same pipeline.The intake interface 1 of two-position three way magnetic valve connects and drives the gas source of the gas, and the interface 2 of giving vent to anger of two-position three way magnetic valve is connected with the driving gas interface of pneumatic on-off valve, and another of two-position three way magnetic valve interface 3 of giving vent to anger is used to drive gas emptying.
The practical implementation process:
1, cut-in pressure sensor in the pipeline of pressurized gas bulking system, its electrical signal exports the PLC control module to, and the relay switch of PLC control module links to each other with two-position three way magnetic valve.
2, the pipeline of hand switch valve with the pressurized gas bulking system is connected, pneumatic on-off valve is connected with vacuum pump 7.
3, the pneumatic control of pneumatic on-off valve: the driver module of pneumatic on-off valve (drive gas interface) and the two-position three way magnetic valve interface 2 of giving vent to anger is connected.
4, drive source of the gas (drive gas and adopt nitrogen or pressurized air, 0.6～1.0MPa press solenoid valve technical requirements setting) and be connected with two-position three way magnetic valve intake interface 1, the two-position three way magnetic valve interface 3 of giving vent to anger is used to drive gas emptying.
5, solenoid valve working method: one-in-and-one-out: when the two-position three way magnetic valve coil electricity, interface 1 leads to interface 2, and interface 3 is closed; When electromagnetic valve coil cut off the power supply, interface 1 was closed, and interface 2 leads to interface 3;
6, vacuum protector work:
At first set the PLC control module: setting pressure is during less than 0.03MPa, and PLC control module relay switch is opened; During greater than 0.03MPa, relay switch cuts out.
When needing to use vacuum system, at first emptying bulking system pressure is opened hand switch; When pressure transducer detects system pressure less than 0.03MPa, the output relay switch opens of PLC control module, two-position three way magnetic valve coil electricity; Drive gas and advance, output to pneumatic on-off valve from the interface 2 of giving vent to anger, the jettron valve events from two-position three way magnetic valve intake interface 1; Open valve, the pressurized gas bulking system is communicated with vacuum pump, vacuum system work.When if pressure transducer detects system pressure greater than 0.03MPa; Even the hand switch valve is opened, but the output relay switch of PLC control module is in closed condition, two-position three way magnetic valve coil no electric circuit; Drive gas and can not drive pneumatic on-off valve work; Pneumatic on-off valve is failure to actuate, and can not open valve, and the pressurized gas bulking system can not be communicated with vacuum pump yet.
Like this; Even because operator's misoperation; Open the vacuum manually-operated gate; Vacuum system can not be communicated with the pressurized gas bulking system, and vacuum pump is protected vacuum system and personal safety effectively with regard to not spraying pumping fluid owing to inlet pressure is excessive, damage vacuum system, causing situation such as personal injury and security incident.
