Ethylene oxide sterilization cabinet door seal pressure constant system with alarm device
The invention discloses an ethylene oxide sterilization cabinet door seal pressure constant system with an alarm device. The ethylene oxide sterilization cabinet door seal pressure constant system with the alarm device is characterized in that pneumatic ball valves comprise a first pneumatic ball valve and a second pneumatic ball valve, the first pneumatic ball valve and the second pneumatic ballvalve are connected with the signal output end of a PLC through RS232 buses, the first pneumatic ball valve communicates with an air inlet pipe, and the first pneumatic ball valve communicates with anair cylinder; the air cylinder communicates with a door seal inflation sealing gasket, and the air cylinder communicates with the second pneumatic ball valve and is discharged through the second pneumatic ball valve; and a digital pressure gauge communicating with the interior of the air cylinder is arranged outside the air cylinder, the digital pressure gauge is connected with a pressure gauge signal end of the PLC through a signal line, and the alarm device is connected with an alarm device signal end of the PLC through a signal line. The system is simple in structure, scientific and reasonable in design and convenient to operate, the influence of too high or too low air pressure in the door seal inflation sealing gasket on the final sterilization effect is avoided, the service life ofthe door seal inflation sealing gasket is prolonged, and good social and economic benefits are achieved.
一种带有报警装置的环氧乙烷灭菌柜门封压力恒定系统，气动球阀包括第一气动球阀和第二气动球阀，第一气动球阀和第二气动球阀经RS232总线与PLC控制器的信号输出端相连，第一气动球阀与进气口管相连通，第一气动球阀与气缸相连通，气缸与门封充气密封垫相连通，气缸与第二气动球阀相连通，并经第二气动球阀排出，气缸外面装有与气缸内相连通的数字压力表，数字压力表经信号线与PLC控制器的压力表信号端相连，报警装置经信号线与PLC控制器的报警装置信号端相连；本发明结构简单，设计科学合理，操作方便，避免了门封充气密封垫内气压过高或过低影响最终灭菌效果，延长了门封充气密封垫的使用寿命，具有良好的社会和经济效益。
