Abstract
The utility model relates to a sealing performance detection apparatus for a filter. The sealing performance detection apparatus is composed of a precision pressure-reducing valve, an electromagnetic valve, an SMC flow switch, a three-way tube, a precision pressure gauge, a filter to be detected, a double-shaft cylinder, a pipeline and a gas source. The precision pressure-reducing valve is connected to the gas source. The precision pressure-reducing valve, the electromagnetic valve and the SMC flow switch are successively connected to each other by the pipeline. The other end of the SMC flow switch is connected to a first port of the three-way tube. A second port of the three-way tube is connected to the precision pressure gauge. The third port of the three-way tube is connected to one end of the pipeline. The other end of the pipeline is connected to one end of the filter to be detected and the other end of the filter to be detected is connected to the double-shaft cylinder. The sealing performance detection apparatus can be used for a sealing performance detection of not only a common filter but also a ventilated window filter. The sealing performance detection apparatus is convenient to use, high in flexibility and efficiency and is suitable for batch use.
Description
Technical field
The utility model belongs to medical instruments field, particularly the sealing propertytest of the filtrator on transfusion device.
Background technology
At present, the kind of filtrator is divided into two large classes substantially, one is plain filter, the particulate matter in simple filtering liquid medicine, and one is transom filtrator, the not only particulate matter in filtering liquid medicine, and at filtrator position, vent port is set, and air that can be in filters locations emptying transfusion device, the bleeder vent of transom filtrator has one or two, even more, reach the effect of high exhaust.And the device for detecting sealability of filtrator is also to detect respectively according to the difference of filtrator.
Summary of the invention
The utility model provides one both can detect plain filter, can detect again the device for detecting sealability of transom filtrator.
The utility model is to adopt following technical proposals to realize: filter seal pick-up unit is by precise pressure-reducing valve, solenoid valve, SMC flow switch, threeway, precision pressure gauge, filtrator to be detected, twin shaft cylinder, pipeline, source of the gas composition.Precise pressure-reducing valve connects source of the gas, precise pressure-reducing valve, solenoid valve are connected with pipeline successively with SMC flow switch, 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 filtrator to be detected one end, and the filtrator other end to be detected is connected with twin shaft cylinder.Precise pressure-reducing valve is adjusted to rated pressure admission pressure, rated pressure because of filtrator kind different.Filtrator to be detected is transom filtrator, start solenoid valve, and twin shaft cylinder withstands not connecting line one end of transom filtrator, and SMC flow switch shows flow number, and flow number is not the underproof transom filtrator of sealing in range of set value; Filtrator to be detected is plain filter, start solenoid valve, and twin shaft cylinder withstands not connecting line one end of filtrator, tensimeter be fixed on a certain position and mobile be the qualified filtrator of sealing.
The utility model compared with prior art, both can detect plain filter, can detect again the sealing of transom filtrator, and easy to detect, dirigibility is high, and efficiency is high, was applicable to using in batches.
accompanying drawing explanation
Fig. 1 structural representation of the present utility model, 1-precise pressure-reducing valve, 2-solenoid valve, 3-SMC flow switch, 4-threeway, 5-precision pressure gauge, 6-filtrator to be detected, 7-twin shaft cylinder, 8-pipeline, 9-source of the gas.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, filter seal pick-up unit is by precise pressure-reducing valve (1), solenoid valve (2), SMC flow switch (3), threeway (4), precision pressure gauge (5), filtrator to be detected (6), twin shaft cylinder (7), pipeline (8), source of the gas (9) composition.Precise pressure-reducing valve connects source of the gas (9), precise pressure-reducing valve, solenoid valve are connected with pipeline successively with SMC flow switch, 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 filtrator to be detected one end, and the filtrator other end to be detected is connected with twin shaft cylinder.Precise pressure-reducing valve is adjusted to rated pressure admission pressure, rated pressure because of filtrator kind different.Filtrator to be detected is transom filtrator, start solenoid valve, and twin shaft cylinder withstands not connecting line one end of transom filtrator, and SMC flow switch shows flow number, and flow number is not the underproof transom filtrator of sealing in range of set value.Setting value is first tested concrete range of set value by qualified product, and it is qualified to determine whether by range of set value.At present, the bleeder vent that has transom filtrator is by more than two and two, and the utility model also can detect the sealing of this type of porous breathable window filtrator.Filtrator to be detected is plain filter, start solenoid valve, and twin shaft cylinder withstands not connecting line one end of filtrator, tensimeter be fixed on a certain position and mobile be the qualified filtrator of sealing.Determining of a certain position first tested concrete a certain position by qualified product, and it is qualified to determine whether by a certain position.Device of the present invention can be checked the sealing of existing filtrator, and efficiency is high, and dirigibility is high, is applicable to using in batches.
Above embodiment is only for the utility model is described, and is not limitation of the utility model, and the those of ordinary skill in relevant technologies field, in the situation that not departing from spirit and scope of the present utility model, can also make a variety of changes and modification.Therefore all technical schemes that are equal to also belong to protection category of the present utility model.
