Abstract
The invention provides an interfacial tension test device, which comprises a sample tube for loading a sample and a tube sleeve provided with an observation window, wherein the sample tube is arranged in the tube sleeve and closed and fixed. The tube sleeve comprises a sleeve body and a sleeve cap which are connected by screw threads. The interfacial tension test device of the invention has the advantages of firm structure, flexible installation and convenient use; the torque force is borne by the tube sleeve; when the sample tube and the tube sleeve are fixed by glue, the sample tube is easy to take out, place and clean; and because the rear section of the sleeve body close to the screw thread part is provided with pores and the corresponding inner wall is processed with an annular guide groove, the sample liquid overflowed during loading a sample and covering a seal gasket or the sleeve cap is guided out so as to avoid polluting an instrument.
Description
Technical field
The present invention relates to a kind of instrument accessory of measuring interfacial tension, relate in particular to a kind of interfacial tension test device.
Background technology
Interfacial tension is the master data of fluid interface character; It is the important parameter of field new product developments such as oil, chemical industry, commodity, production application; Have very important theory and using value, be widely used in fields such as new product development such as oil-field development (tertiary oil recovery), surfactant evaluation, washing agent and agricultural chemicals.The liquid-liquid interface tension parameters extensively adopts rotation to drip the method test at present.Drip in the method test in rotation, existing proving installation mainly contains two types: one type is plexi-glass tubular, and one type is quartz ampoule.Plexi-glass tubular is made up of body and pipe cap two parts, and body and pipe cap are used gasket seal therebetween with being threaded.Quartz ampoule is made up of pipe end cover, quartzy body and quartz ampoule muzzle and pipe cap, and quartzy body sealed end and end cover are gluing fixing, and quartzy body openend and mouthpiece cover are gluing fixing, and pipe cap is connected with mouthpiece cover through screw thread, uses gasket seal therebetween.In measuring process; Find that all there is following defective in said two products: (1) interfacial tensimeter motor directly drives the plexi-glass tubular high speed rotating or drives the quartz ampoule high speed rotating through pipe end cover; Whole torsion is all directly born by plexi-glass tubular or quartzy body, causes quartz ampoule or plexi-glass tubular to twist off breakage easily; (2) when test liquid when muddy (as emulsification takes place), the tested object in plexi-glass tubular or the quartz ampoule is unintelligible, and influence is observed and measured; Pipe cap is added a cover on body (plexi-glass tubular) or mouthpiece cover (quartz ampoule) when (3) using, and rotary threaded connects fastening, introduces bubble easily, and influence is measured; (4) pad embeds and is not easy in the pipe cap to take out and clean.Simultaneously, plexi-glass tubular also exists can not tolerate temperature more than 60 ℃, and the organic glass screw thread uses wearing and tearing to cause for a long time and can't closely fix or leakage, can not adopt problems such as strong solvent organic solvent such as chloroform washing.
Summary of the invention
The object of the invention in order to overcome the problem that above-mentioned prior art exists, provides a kind of interfacial tension test device firm in structure, flexible for installation, easy to use exactly.
In order to achieve the above object; The present invention has adopted following technical scheme: a kind of interfacial tension test device, comprise the sample hose that is used for load sample, and be characterized in; Also comprise a pipe box that is provided with watch window, described sample hose is arranged in the pipe box and is closedly fixed.
Described pipe box comprises body and cap bag, and body and cap bag are threaded.
Described body is columnar structured; Be provided with the inner chamber adaptive in the body with sample hose; The body front end is the solid cylinder blind end of undergauge, and body middle part is arranged with two long trough watch windows, and the body rear end is that openend and being provided with is used for the external thread that is threaded with cap bag.
Be provided with the interior step that a circle hole enlargement forms in the pipe of described body rear end, a gasket seal is arranged on this interior step, and sealing links to each other with cap bag with described sample hose respectively in the inside and outside both sides of gasket seal.
Described cap bag is provided with and is used for the internal thread that is threaded with body, and on cap, is provided with one and is used to inject or the axially extending bore of draw samples.
Described sample hose links to each other with the body of pipe box is gluing.
Described body afterbody is provided with the aperture that radially connects tube wall, and the body inwall is having a circle diversion trench corresponding to aperture place ring cutting, and diversion trench is communicated with aperture; Described sample hose activity is inlaid in the body of pipe box.
Interfacial tension test device of the present invention makes it compared with prior art owing to adopted above technical scheme, has following advantage and characteristics:
1, the torsion of instrument motor high speed rotating generation is born by pipe box, has protected sample hose, makes sample hose can adopt the low materials processing of torsibility simultaneously, and frangible has not been practiced thrift use cost;
2, pipe box drives the sample hose high speed rotating, and the view window high speed rotating on the pipe box has stroboscopic effect, makes the sample object of observation more clear;
3, sample hose embeds in the pipe box, because sample hose is shorter than pipe box, segment trailer is processed to form the pad chamber behind the pipe box body simultaneously, makes load sample and to add a cover pad easy to operate, also can prevent the bubble introducing;
4, sample hose and pipe box both can gluingly be fixed, and permanent the use also can non-gluedly be fixed, and conveniently installed, dismantle, clean sample hose;
5, under sample hose and the non-glued fixing situation of pipe box; The body back segment is processed with aperture near the threaded portion and corresponding inwall place is processed with annular diversion trench; Can avoid polluting instrument with coming out at load sample, the sample liquids water conservancy diversion that overflows when sealing pad or cap bag.
