Description
Technical field
The invention belongs to medical instruments field, particularly to the sealing propertytest of the filter on transfusion device.
Background technology
At present, the kind of filter is divided into two big classes substantially, one is plain filter, the particulate matter in simple filtering liquid medicine, and one is transom filter, the not only particulate matter in filtering liquid medicine, and steam vent is set at filter position, it is possible to and the air in filters locations emptying transfusion device, the air-vent of transom filter has one or two, the most, reach the effect of high exhaust.And the device for detecting sealability of filter is also based on the difference of filter and detects respectively.
Summary of the invention
The present invention provides one both can detect plain filter, can detect again the device for detecting sealability of transom filter.
The present invention is to use following technical proposals to realize: filter seal detection device is made up of precise pressure-reducing valve, magnetic valve, SMC flow switch, threeway, precision pressure gauge, filter to be detected, twin shaft cylinder, pipeline, source of the gas.Precise pressure-reducing valve, connect source of the gas, precise pressure-reducing valve, magnetic valve are sequentially connected with SMC flow switch pipeline, the SMC flow switch other end is connected with threeway first interface, threeway the second interface connects precision pressure gauge, threeway the 3rd interface connecting line one end, the pipeline other end connects filter one end to be detected, and the filter other end to be detected connects with twin shaft cylinders.Precise pressure-reducing valve is adjusted to rated pressure admission pressure, and rated pressure is different because of filter kind.Filter to be detected is transom filter, starts magnetic valve, makes twin shaft cylinder withstand transom filter and is not connected with pipeline one end, and SMC flow switch display flow number, flow number is not then sealing underproof transom filter in range of set value；Filter to be detected is plain filter, starts magnetic valve, makes twin shaft cylinder withstand filter and be not connected with pipeline one end, and Pressure gauge is fixed on a certain numerical value and does not move then qualified for sealing filter.
The present invention compared with prior art, both can detect plain filter, can detect again the sealing of transom filter, easy to detect, and flexibility is high, and efficiency is high, is suitable for batch and uses.
Accompanying drawing explanation
The structural representation of Fig. 1 present invention, 1-precise pressure-reducing valve, 2-magnetic valve, 3-SMC flow switch, 4-threeway, 5-precision pressure gauge, 6-filter to be detected, 7-twin shaft cylinder, 8-pipeline, 9-source of the gas.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is further described.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
As shown in Figure 1, filter seal detection device is by precise pressure-reducing valve (1), magnetic valve (2), SMC flow switch (3), threeway (4), precision pressure gauge (5), filter to be detected (6), twin shaft cylinder (7), pipeline (8), source of the gas (9) forms.Precise pressure-reducing valve connects source of the gas (9), precise pressure-reducing valve, magnetic valve are sequentially connected with SMC flow switch pipeline, the SMC flow switch other end is connected with threeway first interface, threeway the second interface connects precision pressure gauge, threeway the 3rd interface connecting line one end, the pipeline other end connects filter one end to be detected, and the filter other end to be detected connects with twin shaft cylinders.Precise pressure-reducing valve is adjusted to rated pressure admission pressure, and rated pressure is different because of filter kind.Filter to be detected is transom filter, starts magnetic valve, makes twin shaft cylinder withstand transom filter and is not connected with pipeline one end, and SMC flow switch display flow number, flow number is not then sealing underproof transom filter in range of set value.Setting value first tests concrete range of set value by qualified product, and it is qualified to be determined whether by range of set value.At present, the air-vent having transom filter is by two and two or more, and the present invention also can detect the sealing of this type of porous breathable window filter.Filter to be detected is plain filter, starts magnetic valve, makes twin shaft cylinder withstand filter and be not connected with pipeline one end, and Pressure gauge is fixed on a certain numerical value and does not move then qualified for sealing filter.The determination of a certain numerical value first tests concrete a certain numerical value by qualified product, and it is qualified to be determined whether by a certain numerical value.Assembly of the invention can check the sealing of existing filter, and efficiency is high, and flexibility is high, is suitable for batch and uses.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, about the those of ordinary skill of technical field, without departing from the spirit and scope of the present invention, it is also possible to make a variety of changes and modification.The technical scheme of the most all equivalents falls within the protection category of the present invention.
