Abstract
The utility model relates to a sealing type capillary tube viscosity measuring instrument which is an instrument used for measuring the viscosities of fluids. The sealing type capillary tube viscosity measuring instrument is composed of a viscometer main body, a capillary tube and a three-way valve, wherein, an upper opening of the viscometer main body is provided with a grinding opening plug by which the viscometer main body is communicated with the three-way valve through an air guiding tube. A small ball at the upper part of the capillary tube and a small ball at the lower part of the capillary tube are communicated through a communicating tube. The lower part of the capillary tube is communicated with the lower part of the viscometer main body. The upper part of the capillary tube is communicated with the three-way valve through the connecting tube. The other end of the three-way valve is connected with an ear washing ball. The three-way valve is a three-way valve two arbitrarily ends of which are communicated, or three ends of which are communicated.
Description
The utility model is a kind of instrument that is used to measure fluid viscosity, belongs to the technical field that the fluid measurement instrument is made.
Viscosity meter is the instrument that is used to measure fluid (liquids and gases) viscosity.Be mainly used in the researchs such as physical chemistry, polymer physics, also can be used for the detection of the mobile property of fluid product in the enterprise.Viscosity meter is broadly divided into capillary viscosimeter, rotational viscosimeter and falling-sphere viscometer three classes.Wherein the first kind is the most commonly used, as the viscosity meter of Ovshinsky (Ostwald) viscosity meter, Ubbelohde (Ubbelohde) viscosity meter, Sai Shi (Saybolt) viscosity meter, Yin Shi (Engler), Lei Shi (Redwood) viscosity meter etc.Capillary viscosimeter (as Ovshinsky, Ubbelohde etc.) commonly used at present is because its open by design, liquid in the viscosity meter and steam thereof directly contact with outside air, therefore can only be to the solution that adopts weak volatile solvent, be difficult for and liquid that liquid that airborne oxygen and carbon dioxide reacts and steam are nontoxic is measured, usable range is very limited.From the reported in literature of U.S. chemical abstract (CA) in recent years, more external design proposal and the patent that closed viscosity meters are also arranged, it is all bigger that the mentality of designing of these designs and structure differ, wherein the design of capillary viscosimeter is few, but all different depths have a narrower shortcoming of the scope of application.
Goal of the invention of the present utility model just provides a kind of applied range, closed capillary viscosimeter easy to use, simple in structure.
Closed capillary viscosimeter of the present utility model is made up of viscosity meter body, kapillary, T-valve, being provided with a ground chock plug viscosity meter body suitable for reading is connected by wireway the viscosity meter body with T-valve, between top capillaceous bead and the bottom bead by being connected communicating pipe, bottom capillaceous is communicated with the bottom of viscosity meter body, top capillaceous is communicated with T-valve by connecting pipe, another termination ear washing bulb of T-valve.T-valve is the T-valve that but any two ends is communicated with or three ends are straight-through.
Advantage of the present utility model is to overcome the shortcoming of traditional open viscosity meter.Adopted circulating closed system in the design, make intrasystem liquids and gases and surrounding air isolated fully, therefore to volatilization or nonvolatile solution system and in air liquid unsettled or the toxic effect of steam all suitable equally, expanded range of application greatly, and it is simple in structure, easy to use.
Fig. 1 is a general structure synoptic diagram of the present utility model.Viscosity meter body 1, cold 2 of ground, wireway 21, kapillary 3, top bead 31, bottom bead 32, communicating pipe 33, connecting pipe 34, T-valve 4, ear washing bulb 5 are wherein arranged.
Embodiment of the present utility model is as follows:
This viscosity meter is made of a viscosity meter body, a ground chock plug, a T-valve and three connection flexible pipes and an ear washing bulb.The design of its assembly and the last visible accompanying drawing 1 of assembling effect, the critical piece of this viscosity meter comprises that viscosity meter body, ground chock plug and T-valve all make of glass, the flexible pipe that connects usefulness can be selected emulsion tube, proofed sleeve or teflon hose for use, ear washing bulb can be integral by connected flexible pipe, and also available common ear washing bulb and flexible pipe are glued together and form.
Structurally viscosity meter body suitable for reading is provided with a ground chock plug viscosity meter body is connected with T-valve by wireway, between top capillaceous bead and the bottom bead by being connected communicating pipe, bottom capillaceous is communicated with the bottom of viscosity meter body, top capillaceous is communicated with T-valve by connecting pipe, another termination ear washing bulb of T-valve.
The using method of this viscosity meter is as follows:
1) with the solution to be measured of packing in the viscosity meter body, connects pipeline;
2) the viscosity meter body is put into water bath with thermostatic control, be fixed, keep kapillary vertical with iron stand;
3) the swivel tee valve is only connected ear washing bulb 5 and pipe wireway 21, clutches the ear washing bulb pressurization, the solution in the big ball of viscosity meter body is pressed in the bead of kapillary top, till no longer rising to liquid level;
4) clutch ear washing bulb and do not put, a swivel tee valve on-tube ear washing bulb 5 and connecting pipe 34 are slowly decontroled ear washing bulb, utilize negative pressure the solution in the big ball of viscosity meter to be continued to suck the bead of kapillary top;
5) if through step 3) and 4) the still underfill of bead of postcapillary top, then repetitive process 3), 4), till being full of two beads;
6) three mouths of swivel tee valve connection T-valve make three mouth intercommunications, read the flushing time of solution;
Only need the ground chock plug is extracted when 7) changing solution to be measured, change to connect again after finishing and get final product.
Advantages such as that this viscosity meter has is simple in structure, easy to use, applied range, its cost of manufacture is only high by 30～40% than the Ubbelohde viscometer of same model in addition, so have promotional value.
