Description
Technical field
The utility model relates to a kind of testing instruments, is specifically related to a kind of check sampling pipe.
Background technology
The glass tube that current inspection adopts diameter unanimous between the higher and lower levels more, its front end is taper suction nozzle, open rearward end, its Problems existing is: one, because caliber is consistent, there is no scale marker, need the stopple coupon selecting dimension according to the requirement of inspection during operation, therefore those skilled in the art need the stopple coupon preparing more specification; Two, troublesome poeration, when stopple coupon is longer, opening up inadequate operator's sampling for arm can have difficulties, and also can cause the waste of material simultaneously.
In sum, need a kind of new check sampling pipe of design to make up above-mentioned defect.
Utility model content
The utility model proposes a kind of check sampling pipe, for solving the defect of sampling difficulty and waste material in prior art.The utility model structure is simple, and sampling is convenient, and it facilitates any operator to sample, and saves material.
The technical solution of the utility model is achieved in that
A kind of check sampling pipe, it comprises body and piston; Described body is provided with scale marker; Body one end is provided with taper suction nozzle, its other end opening, and the opening of taper suction nozzle is less than the other end opening of body; Piston comprises nut, packing ring, piston main body and rotary switch, and piston main body is provided with perforation, and nut is arranged on piston main body one end, and rotary switch is movably connected in the piston main body other end, and packing ring is arranged between nut and piston main body; Body is arranged in perforation.
Preferably, check sampling pipe is provided with ear washing bulb, and ear washing bulb is set on body other end opening.
Wherein, packing ring comprises rubber washer and polytetrafluoro packing ring, and rubber washer, polytetrafluoro packing ring are installed in piston main body one end, and rubber washer is located between nut and polytetrafluoro packing ring.
Wherein, piston is made up of politef.
Wherein, the cross section of body is circular or rectangle.
Wherein, the caliber of body is consistent.
Preferably, the caliber of body near taper suction nozzle one end is greater than the caliber of body near piston one end.
Compared with prior art, the utility model advantage specific as follows:
(1) setting of the utility model body upper piston, not only handled easily, can also accomplish material zero loss; And piston is made up of politef, be applicable to the sampling of various strong acid and strong base sample.
(2) setting of the utility model body high scale mark, conveniently in sampling process, read required sampling amount, therefore the utility model check sampling pipe is applicable to different sampling amounts.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model check sampling pipe first angle;
Fig. 2 is the structural representation of the utility model check sampling pipe second angle;
Fig. 3 is the structural representation of the utility model check sampling pipe the 3rd angle;
Fig. 4 is the structural representation of the utility model piston.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to figs. 1 through Fig. 4, a kind of check sampling pipe, it comprises body 1 and piston 2; Described body 1 is provided with scale marker 3; Body 1 one end is provided with taper suction nozzle 11, its other end opening, and the opening of taper suction nozzle 11 is less than the other end opening of body 1; Piston 2 comprises nut 21, packing ring, piston main body 23 and rotary switch 24, piston main body 23 is provided with perforation 25, nut 21 is arranged on piston main body 23 one end, and rotary switch 24 is movably connected in piston main body 23 other end, and packing ring is arranged between nut 21 and piston main body 23; Body 1 is arranged in perforation 25.The utility model packing ring comprises rubber washer 221 and polytetrafluoro packing ring 222, and rubber washer 221, polytetrafluoro packing ring 222 are installed in piston main body 23 one end, and rubber washer 221 is located between nut 21 and polytetrafluoro packing ring 222.
The setting of the utility model body high scale mark, conveniently in sampling process, read required sampling amount, therefore the utility model check sampling pipe is applicable to different sampling amounts.The setting of the piston of the utility model check sampling pipe, not only handled easily, can also accomplish material zero loss; And piston is made up of politef, be applicable to the sampling of various strong acid and strong base sample.
The cross section of the utility model body is circular or rectangle, and other shape according to the actual requirements, can also be arranged in the cross section of body by those skilled in the art; And the caliber of body can be arranged to unanimously by those skilled in the art according to the actual requirements, or be arranged to the caliber of body near taper suction nozzle one end and be greater than the caliber of body near piston one end.
During the utility model sampling, operator's taper suction nozzle directly inserts the following certain altitude of sample liquid level (this height is determined according to required sampling amount), treat that in body, liquid level and pipe foreign minister are at ordinary times, the other end opening of body is pressed tight with hand, check sampling pipe is proposed, then sample in pipe is put into sample bottle.
As another embodiment, the utility model also can be provided with ear washing bulb on check sampling pipe, and ear washing bulb is set on body other end opening; When needs sample, piston is opened by operator, and pressing ear washing bulb, is inserted in liquid by taper suction nozzle; Slowly decontroled by ear washing bulb, liquid is sucked in body, when the liquid sucked reaches the scale marker of required sampling amount, sampling completes, and piston is closed by operator, and the sample in stopple coupon can be made not flow out, check sampling pipe is taken out from liquid, namely completes sampling work; During setting-out product, piston is turned on and the liquid that check sampling pipe is drawn out can be put into inspection machine.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
