Description
Technical Field
The utility model relates to a water shortage alarm device, in particular to a water ring vacuum pump device with a water shortage alarm for an ethylene oxide sterilization cabinet.
Background
When the ethylene oxide sterilizing cabinet is used normally, five factors are involved in affecting the sterilizing effect: temperature, pressure, humidity, ethylene oxide concentration, sterilization time. The pressure here usually refers to the vacuum degree, the vacuum degree determines the content of ethylene oxide in the residual air, and the residual air can directly affect the ethylene oxide gas, heat and humidity to reach the inside of the sterilized object, so the effect of the vacuum degree on the sterilization effect is huge during the sterilization process, especially before humidification, the pressure (vacuum degree) generally adopts a water ring vacuum pump, and when the water ring vacuum pump normally works, if there is no water, the water pressure is small or the water flow is small, the service life of the water ring vacuum pump will be greatly affected, thereby improving the sterilization cost and reducing the working efficiency, therefore, how to avoid the above problems of the water ring vacuum pump to affect the final sterilization effect is not disclosed.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model aims at providing an ethylene oxide sterilization cabinet is with water ring vacuum pump device that has the water shortage warning, can effectively solve water ring vacuum pump during operation, because discharge is little or do not have water to cause the harm to water ring vacuum pump, leads to the problem of final sterilization effect.
In order to achieve the purpose, the utility model provides a technical problem be, an ethylene oxide sterilization cabinet is with water ring vacuum pump device that has the warning of lack of water, including water ring vacuum pump, pneumatic ball valve and flow detection switch, water ring vacuum pump's inlet tube on be equipped with the valve, be equipped with flow monitoring switch on the pipeline between water ring vacuum pump and the valve, flow monitoring switch links to each other with alarm device through the wire, water ring vacuum pump's vacuum pump mouth is linked together through the vacuum port on pipeline and the ethylene oxide sterilization cabinet, is equipped with pneumatic ball valve on the pipeline between the vacuum port on water ring vacuum pump and the ethylene oxide sterilization cabinet.
The utility model discloses simple structure, convenient operation, easy installation has effectively avoided water ring vacuum pump working process, because discharge is little or do not have water to cause the problem of harm to water ring vacuum pump, improves work efficiency, has good society and economic benefits.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
The water ring vacuum pump device comprises a water ring vacuum pump, a pneumatic ball valve and a flow detection switch, wherein a valve 6 is arranged on a water inlet pipe 3 of the water ring vacuum pump 2, a flow monitoring switch 7 is arranged on a pipeline between the water ring vacuum pump 2 and the valve 6, the flow monitoring switch 7 is connected with an alarm device 8 through a lead, a vacuum pump opening of the water ring vacuum pump 2 is communicated with a vacuum opening in the ethylene oxide sterilization cabinet 1 through a pipeline, and the pneumatic ball valve 5 is arranged on a pipeline between the vacuum openings in the water ring vacuum pump 2 and the ethylene oxide sterilization cabinet 1.
In order to ensure better implementation effect, the water ring vacuum pump 2 is provided with a communicated water outlet pipe 4, and a water discharge valve is arranged on the water outlet pipe 4.
The alarm device 8 is an IP65 explosion-proof 1010AC 908AC type audible and visual alarm.
The flow monitoring switch 7 is an RFS-D-D010Ex type flow monitoring switch.
The vacuum pump port of the water ring vacuum pump 2 is communicated with a pipeline through a flange plate 2-1.
When the utility model works, the flow monitoring switch 7 and the alarm device 8 are provided with a power supply, which can be a lithium battery (DC 12V) generally, the flow alarm value of the flow monitoring switch 7 (the function of the flow monitoring switch 7) is manually set, the valve 6 is opened, water enters the water ring vacuum pump 2 through the water inlet and the first pipeline 3, the water ring vacuum pump 2 starts to work, the ethylene oxide sterilizing cabinet 1 is pumped, the flow monitoring switch 7 monitors the water flow in the first pipeline 3 in real time and whether the water flows or not, when the water flow reaches a set flow alarm value, the on-off state of a signal is output by means of the switch electric contact, the flow monitoring switch 7 transmits the signal to the alarm device 8, the alarm device reminds an operator of checking related aspects through the change of sound and light, and measures are taken to ensure the normal work of the water ring vacuum pump.
The utility model discloses simple structure, convenient operation, easy installation has effectively avoided water ring vacuum pump working process, because discharge is little or do not have water to cause the problem of harm to water ring vacuum pump, prolongs water ring vacuum pump's life to improve work efficiency, guarantee final sterilization effect, have good society and economic benefits.
