Abstract

Pressure-pipe type film film pipe leakage detection apparatus in a kind of, is characterized in: comprise the pressure gas source part, pressure-reducing valve, Pressure gauge, switch valve and the film pipe joint that connect with pipeline successively, be full of pressed gas in pressure gas source part; Comprise film pipe plug, the two-port of film pipe joint and the clogging film pipe to be detected of film pipe plug difference; Comprise detection groove, detect in groove and be marked with tracer liquid, film pipe to be detected is immersed in tracer liquid.Adopt above-mentioned leakage detection apparatus, after reducing pressure by pressure-reducing valve, by Pressure gauge measuring air pressure, open switch valve, making pressed gas enter in film pipe, then whether having bubble to ooze out from film pipe by observing, just can determine the particular location of film pipe whether existing defects and defect fast, therefore, there is detection advantage reliably, conveniently and intuitively.

Description

Interior pressure-pipe type film film pipe leakage detection apparatus
Technical field
The utility model relates to film pipe production technical field, pressure-pipe type film film pipe leakage detection apparatus in specific design one.
Background technology
Membrane separation technique and device have now been widely used in the numerous areas such as chemical industry, biology, medicine, food, water treatment, are the important one in modern technologies.Tubular membrane is a kind of form of diffusion barrier, and general caliber 5-25mm, mostly is inner pressed, and using non-woven fabrics etc. as supporting layer, inner surface is attached with the separating layer of polymer.Usual tubular membrane is one group with several to hundreds of root, by resin cast, consists of tubular membrane component, is applied to different field.Because film pipe caliber in tubular membrane component is comparatively large, negligible amounts, if wherein there is defective film pipe, will greatly affect membrane module performance, and normally can not use, cause greater loss.Therefore, in tubular membrane component production process, if can find in advance and reject defective film pipe, the yield rate of tubular membrane component can be ensured, reduce loss, and be strong guarantee to product quality.
Summary of the invention
The utility model for solve in known technology the technical problem that exists and provide a kind of detect reliable, convenient, intuitively in pressure-pipe type film film pipe leakage detection apparatus.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
Pressure-pipe type film film pipe leakage detection apparatus in a kind of, is characterized in that: comprise the pressure gas source part, pressure-reducing valve, Pressure gauge, switch valve and the film pipe joint that connect with pipeline successively, be full of pressed gas in pressure gas source part; Comprise film pipe plug, the two-port of film pipe joint and the clogging film pipe to be detected of film pipe plug difference; Comprise detection groove, detect in groove and be marked with tracer liquid, film pipe to be detected is immersed in tracer liquid.
The technical scheme that the utility model also can be taked is:
Described pressed gas is compressed air or inertia pressure gas.
Described tracer liquid is water or alcohol.
The advantage that the utility model has and good effect are:
Adopt above-mentioned leakage detection apparatus, after reducing pressure by pressure-reducing valve, by Pressure gauge measuring air pressure, open switch valve, making pressed gas enter in film pipe, then whether having bubble to ooze out from film pipe by observing, just can determine the particular location of film pipe whether existing defects and defect fast, therefore, there is detection advantage reliably, conveniently and intuitively.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, pressure gas source part; 2, pressure-reducing valve; 3, Pressure gauge; 4, switch valve; 5, film pipe joint; 6, film pipe plug; 7, groove is detected.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, pressure-pipe type film film pipe leakage detection apparatus in a kind of, is made up of following a few part:
Comprise the pressure gas source part 1, pressure-reducing valve 2, Pressure gauge 3, switch valve 4 and the film pipe joint 5 that connect with pipeline successively.Be full of pressed gas in pressure gas source part, the pressure of pressed gas is generally 1-12Mpa, and pressed gas can adopt compressed air, also can adopt inertia pressure gas, as nitrogen, argon gas etc.
Comprise film pipe plug 6, the two-port of film pipe joint and the clogging film pipe to be detected of film pipe plug difference.Concrete, the diameter of film pipe plug and film pipe joint and the diameter compatible of film pipe close, when film pipe plug is inserted into the Single port of film pipe, this port of film pipe to be detected is sealed completely, when film pipe joint is inserted into the another port of film pipe, formed to seal with this port of film pipe to be detected and contact, carry out the circulation of gas by means of only the central through hole on film pipe joint.At present, the normal diameter adopting film pipe is 3-25mm, according to different film pipe, can be equipped with film pipe plug and the film pipe joint of many group correspondingly-sized, to adapt to the detection needs of the film pipe of different tube diameters.
Comprise and detect groove 7, detect in groove and be marked with tracer liquid.Tracer liquid can adopt water, alcohol etc.Film pipe to be detected is immersed in tracer liquid.
When this leakage detection apparatus is hunted leak to film pipe, be first connected with film pipe one end by film pipe joint, the film pipe other end is connected with film pipe plug; Pressed gas in pressure gas source part is reduced to the pressure limit detected for film pipe by pressure-reducing valve, be generally 0.01-0.1MPa, by Pressure gauge measuring air pressure, after opening switch valve, pressed gas enters in film pipe, film pipe is immersed in and detects a period of time in groove, observe and whether have bubble to ooze out from film pipe along whole film length of tube.If do not have bubble to ooze out from film pipe, namely represent that film pipe is intact, if there is bubble to ooze out, then illustrates and ooze out bubble place defectiveness.
Adopt this leakage detection apparatus to detect film pipe, can not have a negative impact to film pipe in testing process, not residual, therefore, the use of film pipe can not be affected, there is safe and reliable advantage.This leakage detection apparatus is applicable to the defects detection of tube type filter membrance, milipore filter, NF membrane, reverse osmosis membrane, can realize the quality control in early stage of film pipe, ensure the yield rate of membrane module and product, reduce defect rate, enhance productivity, reduce economic loss.
