Description
Technical field
This utility model is related to measuring instrument technical field, especially relates to a kind of Ubbelohde viscometer.
Background technology
In the viscosimetry of measurement Molecular Weight for Polyacrylamide, using the intrinsic viscosity of Dilution polyacrylamide,
Need using dilution type Ubbelohde viscometer in this experimental technique.In measurement process, dilution sample solution when, need with ear washing bulb to
Inflate bubbling inside Ubbelohde viscometer, and when testing, need in measurement capillary upper mounting of syringe draw sample solution, it
Syringe also to be taken off afterwards, carry out necessary seal and drop a hint the operation such as outstanding pipe, not only relatively complicated, waste time and energy, do not allow
Easily grasp, and easy error.
Utility model content
The purpose of this utility model is to provide a kind of Ubbelohde viscometer, and it has the characteristics that to be easy to experimental implementation.
This utility model be employed technical scheme comprise that：Ubbelohde viscometer, including liquid injection pipe, this liquid injection pipe bottom is communicated with
The all upwardly extending measurement gentle outstanding pipe of capillary tube, this liquid injection pipe, the equal upper opening of the gentle outstanding pipe of measurement capillary tube, described Ubbelohde
Viscometer also includes a rubber bulb, and the top of this rubber bulb is provided with one-way air inlet mouth, bottom is provided with unidirectional gas outlet, and this rubber
The side wall of ball is provided with atmospheric valve, and meanwhile, the upper opening of this measurement capillary tube is connected to this rubber by one first rubber tube
The one-way air inlet mouth of ball or unidirectional gas outlet, and, the upper opening that this gas hangs pipe is connected with one second rubber tube, this second rubber
The other end of leather hose is communicated to air, and this second rubber tube is provided with air volume regulating valve.
This utility model is compared to the prior art advantageously：It is easy to experimental implementation.Ubbelohde of the present utility model
Viscometer use when, need not be assisted using ear washing bulb, more avoid using syringe extraction sample solution, extremely convenient,
More improve operating efficiency.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated：
Fig. 1 is the front view of embodiment of the present utility model.
In figure：
10th, liquid injection pipe；
20th, measure capillary tube, the 21, first rubber tube, 22, rubber bulb, 221, one-way air inlet mouth, 222, unidirectional gas outlet,
223rd, atmospheric valve；
30th, gas hangs pipe, the 31, second rubber tube, and 32, air volume regulating valve.
Specific embodiment
Embodiment, as shown in Figure 1：Ubbelohde viscometer, including liquid injection pipe 10, this liquid injection pipe 10 bottom is communicated with all prolongs upwards
The gentle outstanding pipe 30 of measurement capillary tube 20 stretched, this liquid injection pipe 10, the equal upper opening of the gentle outstanding pipe 30 of measurement capillary tube 20.Certainly,
It is same as prior art, this Ubbelohde viscometer also includes the parts such as buffering ball, quantitative ball.
Further say, this Ubbelohde viscometer also includes a rubber bulb 22.The top of this rubber bulb 22 is provided with one-way air inlet
Mouth 221, bottom are provided with unidirectional gas outlet 222, and the side wall of this rubber bulb 22 is provided with atmospheric valve 223.This exhaust-valve 223 is in
Normally off.Meanwhile, the upper opening of this measurement capillary tube 20 is connected to the list of this rubber bulb 22 by one first rubber tube 21
To air inlet 221 or unidirectional gas outlet 222.That is, the one-way air inlet mouth 221 to this rubber bulb 22 is connected when this first rubber tube 21
When, this unidirectional gas outlet 222 is communicated to air；Connect when this first rubber tube 21 to the unidirectional gas outlet 222 of this rubber bulb 22
When, this one-way air inlet mouth 221 is communicated to air.And, the upper opening that this gas hangs pipe 30 is connected with one second rubber tube 31.Should
The other end of the second rubber tube 31 is communicated to air, and this second rubber tube 31 is provided with air volume regulating valve 32.That is, this tolerance is adjusted
Section valve 32 is used for sealing and being vented this second rubber tube 31.When using or when rinse buffering ball and quantitative ball, by this gas
Adjustable valve 32 closes this second rubber tube 31, so that the upper opening that this gas hangs pipe 30 is sealed.Then press this rubber
Ball 22, enters after buffering ball and quantitative ball to sample solution, opens this atmospheric valve 223 and air volume regulating valve 32.Treat this dilution
When sample solution heaves bubble, the upper opening of this measurement capillary tube 20 is connected to this rubber bulb 22 by this first rubber tube 21
Unidirectional gas outlet 222, and the one-way air inlet mouth 221 of this rubber bulb 22 is communicated to air, closes this atmospheric valve 223 and this tolerance
Regulating valve 32, presses this rubber bulb 22, inflates bubbling to inside this Ubbelohde viscometer.
In sum, Ubbelohde viscometer of the present utility model is provided with rubber bulb, rubber bulb there is one-way air inlet function it is easy to
Realize suction or air-blowing.Meanwhile, rubber bulb has atmospheric valve, it is easy to accomplish is vented and need not take off rubber bulb.And, the second rubber
Air volume regulating valve is provided with leather hose, it is easy to accomplish the sealing of the second rubber tube or emptying.So, not only facilitate the behaviour of experiment
Make, and shorten the experimental implementation time, improve conventional efficient.
The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model,
Equivalent structure or equivalent flow conversion that every utilization this utility model description and accompanying drawing content are made, or direct or indirect transport
