Description
The present invention relates to a kind of flowable glass electrode.
In the U.S. Patent application of submitting on May 24th, 1984 (sequence number 614,225), the applicant has proposed a kind of flowable glass electrode.Compare with common flowable glass electrode, the size of this glass electrode is little, and good impact resistance is arranged, and can measure micro-example, and is easy to assembling.
As shown in Figure 4, this glass electrode has stay pipe (23) heat-sealing to receive the two ends of glass reaction tube (22), and stay pipe (23) is received in a sleeve pipe (24) heat-sealing.An interior electrode (25) and interior liquid (26) envelope are advanced in this sleeve pipe (24), form the main body D of flowable glass electrode thus.This main body D is placed in the resin pedestal (27).The diameter of gaseous sample runner pipe (28) equals the diameter of glass reaction tube (22).The former passes two walls (29) of pedestal respectively, and links to each other by connecting pipe (30) calcaneus branches stay tube (23).In main body D, fill with insulating material.
According to this configuration, the heat sealing between pipe (22) and (23) partly has dead space (32).Coupling part (33) between this dead space (32) and the pipe (23) and (28) all is stained with easily and is stayed dirt, causes the obstruction of fluid passage.
In addition, because used heat sealing, reaction tube (22) must have identical thermal expansivity with the glass of stay pipe (23).And because the intensity at heat sealing place is lower, it is relatively poor that runner pipe bears the ability of thermal shock.
Therefore, the configuration aspects in glass electrode still leaves some room for improvement.
An object of the present invention is to provide a kind of flowable glass electrode, and it is not only easy to use, and can address the above problem simply.
This purpose is by realizing according to a flowable glass electrode of the present invention.It comprises: a resin-case that has a hollow cavity, lead to described inner chamber from above-mentioned housing outside in that its opposite end is porose, and be aligned with each other; An interior electrode that is placed in the above-mentioned inner chamber; Straight, a whole hollow glass capillaries, this kapillary passes above-mentioned hole and inner chamber, and the sample channel of a homogeneous diameter is arranged; Centering on above-mentioned sealed engagement mechanism capillaceous and the seal element in the sealed engagement mechanism of above-mentioned hole in above-mentioned lumen openings is in above-mentioned hole; Opening part closely centers on aforementioned tube and catches up with and state the close-fitting stopper in hole outside above-mentioned housing in above-mentioned hole, this stopper is leaving between the seal element at interval along catching up with on the direction in above-mentioned hole to state, to form the space of the housing insulation material of a spread in each hole betwixt; A kind of insulating material that is filled in above-mentioned space; A kind of interior liquid that is full of above-mentioned inner chamber.
In the resin pedestal of this flowable glass electrode, have one be full of in the space of liquid, kapillary passes therebetween.Therefore, this flowable glass electrode does not have common heat sealing part, and is firm in structure, can stand thermal shock.
Because glass capillary is straight, uniform internal diameter is arranged, there is not the bonding part, there is not the heat sealing part yet, so needn't consume sample in useless dead space, dirt is difficult to retain, and also just is not easy to stop up.
In addition, the single straight kapillary done of glass is easy to insert resin base.Like this, make flowable glass electrode according to the present invention than wanting much less the man-hour that prior art took, thereby reduce cost of manufacture greatly.
When reading following detailed description together with appended figure, above-mentioned and further purpose of the present invention and novelty thereof will embody more fully.
Fig. 1 is the cross sectional plan view of the flowable glass electrode embodiment of making according to the present invention;
Fig. 2 is the longitudinal profile front elevation of Fig. 1 embodiment;
Fig. 3 is the skeleton view (part is removed) of Fig. 1, electrode shown in Figure 2;
Fig. 4 is the cross sectional plan view of the previous a kind of flowable glass electrode that proposes.
The present invention's electrode A comprises a resin-case (1) that ellipse garden shape xsect is arranged, a lumen inner chamber (2), and one is parallel to the hole, garden (3) of inner chamber axis and the groove (4) that connects groove (2) and hole (3).Through hole (5) and (6) outwards penetrate the end wall portion (1a) at housing (1) two ends along the long axis direction of inner chamber (2) from inner chamber (2), hole (5) and (6) are coaxially to each other and be connected by inner chamber (2).The inner that each Kong Youyi diameter is less, the center section of intermediate diameters and the bigger outer end of a diameter.
Laying plug (7) and hole (8) for one laterally penetrates housing and stretches to hole (3).Filler opening (9) and (9) reach hole (5) and (6) downwards from the top of resin-case, and filler opening (10) is connected with inner chamber (2) from the resin-case lateral opening.
An interior electrode (11) is placed in the inner chamber (2).One lead (12) one end is linked plug (7), feed hole (3) thus, (3) mid-game becomes coil in the hole, enters inner chamber (2) by groove 4 then, electrode (11) in its other end connected, lead (12) fill insulant (not shown) on every side in groove (4).
(promptly not coupling together) hollow glass capillaries reaction tube (13) straight, integral body provides a uniform sample channel of internal diameter.Pipe (13) passes hole (5) and (6) and inner chamber (2), and the intermediate portion is exposed in the hollow cavity (2).The pipe (13) an end more protruding slightly from the hole (5) of resin-case (1), and the other end in hole (6) from shell ends towards lining indentation as much.
The smaller diameter end of (5) and (6) has sealed kapillary (13) and end wall (1a) part to seal (14) (for example O shape circle) in the hole.
The major diameter part of the hole (5) in stopper (15) and (16) the heel end wall part (1a) and (6) closely matches, and closely encases the outer peripheral face at the two ends of kapillary (13) in hole (5) and (6), and in the end face of axially following pipe (13).The outer face indentation inwards of (6) from the hole of the outer face of stopper (16), a major diameter part 6a is reserved in the outer end of (6) in the hole.One O-ring seal (21) centers on stopper (16), and slightly outwards more outstanding than the outer face of this stopper.The part (15a) of stopper (15) protrudes in outside the resin-case (1), and its shape makes it just in time follow the outer end major diameter part (6a) in the hole (6) of next adjacent electrode to closely cooperate.Like this, as long as the stopper of an electrode (15) is inserted in the hole (6) of next electrode, and, just can be together in series a plurality of flowable glass electrodes by O-ring seal (21) sealing.
Each seal element (14) is with the space B that forms a housing insulation material between corresponding stopper (15) or (16).Insulating material (17), for example silicones charges into this space B by filler opening (9).
A resin lid (18) is placed on the top of resin-case (1) with closed inner chamber (2) and filler opening (9).Lid (18) has sealed inner chamber (2), form an interior liquid space C after, interior liquid (19) injects space C by filler opening (10), uses stopper (20) to clog the end of hole (10) then.
Here described one embodiment of the present of invention, yet the present invention is not limited to the concrete structure of this kind.This concrete structure just in explanation as illustration, rather than determinate.
