Description
Technical field
The utility model relates to a kind of glass capillary tube viscometer liquid getting device.
Background technology
When the experiment that relates to petroleum substance, often need to measure their kinematic viscosity, this just need to use viscosity meter.Because of advantages such as kapillary glass viscosity meter precision are high, simple in structure and easy to use, multiplex kapillary glass viscosity meter in practical viscosity measurement.In actual experiment, multiplex ear washing bulb completes the absorption work of oil sample, if but while once not drawing the desired oil sample volume of experiment, also need to block with hand the big opening end of glass capillary, discharge the air in ear washing bulb, reuse ear washing bulb and carry out absorption work, particularly troublesome, especially the oil sample of giving when less, owing to can not guaranteeing air-proof condition, workload is larger, effect is also bad, sometimes even inhales not oil-feed sample.
Utility model content
The purpose of this utility model is: in order to solve the problem of above-mentioned prior art, provide a kind of glass capillary tube viscometer liquid getting device.
For achieving the above object, the technical solution adopted in the utility model is: the neck of the first steel pipe 3 arranges the second seal valve 8, head and the rubber cap 2 of the seal valve cock 1 on the second seal valve 8 fit tightly, and the entity in seal valve cock 1 and the first steel pipe 3 adopts screw-threaded engagement; An entity in rubber cap 2 and the first steel pipe 3 fits tightly; The first steel pipe 3 lower ends are communicated with rubber ball 4 upper sheds; The under shed of rubber ball 4 is communicated with the second steel pipe 5 upper ends, and the afterbody of the second steel pipe 5 is provided with the first seal valve 7, the second steel pipe 5 lower ends and is communicated with glass tube viscosity meter by rubber tube 6.
The beneficial effects of the utility model are: the first, and simple in structure, easy to operate; The second, for conventional suction method, efficiency is higher; The 3rd, sealing is better, especially when given oil sample is less; The 4th, by rotary seal cock, can change the size of blow vent and then adjustable air inflow.
Accompanying drawing explanation
Fig. 1 is the structural drawing of a kind of glass capillary tube viscometer liquid getting device of the utility model.
Fig. 2 is the utility model sealing rotary rotoplug and rubber cap structural drawing.
Fig. 3 is the utility model the second seal valve structure figure.
Accompanying drawing sign: the cock of 1-seal valve, 2-rubber cap, 3-the first steel pipe, 4-rubber ball, 5-the second steel pipe, 6-rubber tube, 7-the first seal valve, 8-the second seal valve.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
As shown in Figure 1 to Figure 3, head and rubber cap 2 that the neck of the first steel pipe 3 arranges the seal valve cock 1 on the second seal valve 8, the second seal valves 8 fit tightly, and the entity in seal valve cock 1 and the first steel pipe 3 adopts screw-threaded engagement; An entity in rubber cap 2 and the first steel pipe 3 fits tightly; The first steel pipe 3 lower ends are communicated with rubber ball 4 upper sheds; The under shed of rubber ball 4 is communicated with the second steel pipe 5 upper ends, and the afterbody of the second steel pipe 5 is provided with the first seal valve 7, the second steel pipe 5 lower ends and is communicated with glass tube viscosity meter by rubber tube 6.
Principle of work is as follows: when needs suck oil sample toward glass capillary tube viscometer, first seal valve of outwarding winding, the second seal valve, with hand, squeeze out the air in rubber ball 4, screw afterwards the second seal valve 8, oil sample is pressed into the reservoir ball on glass capillary tube viscometer right side under atmospheric pressure effect, after if rubber ball spheroid recovers normally, glass capillary tube viscometer right side oil sample liquid level does not also rise to the height of requirement, screw the first seal valve 7, second seal valve 8 of outwarding winding, extrude after the air in rubber ball 4, screw the second seal valve 8, first seal valve 7 of outwarding winding afterwards, until sucking oil sample liquid level, glass capillary tube viscometer right side meets the requirements of height, this liquid getting device has adopted two seal valves.An entity in seal valve cock 1 and the first steel pipe 3 adopts screw-threaded engagement, fully guaranteed sealing, the head of seal valve cock 1 and rubber cap 2 are tightly fitted, under pressure, an entity in rubber sphere 2 and the first steel pipe 3 is tightly fitted, and has fully guaranteed sealing; By the cock of rotary seal valve, can change the size of blow vent, can regulate the size of throughput.
This cover liquid getting device can effectively be controlled the height that viscosity meter right side sucks oil sample, operability and impermeability are all higher, especially when given oil sample is less, also can draw like a cork the desired oil sample volume of experiment, this covering device can be used for multiple viscosity meter, be particularly useful for the glass tube viscosity meter that requirement sucks designated volume, as dark type viscometer.
Above content is the further description of the utility model being done in conjunction with optimal technical scheme, can not assert that the concrete enforcement of utility model only limits to these explanations.Concerning the utility model person of an ordinary skill in the technical field, not departing under the prerequisite of design of the present utility model, can also make simple deduction and replacement, all should be considered as protection domain of the present utility model.
