Abstract
The utility model relates to a pressure discharging hopper, which is composed of a hopper and a guide tube, a hole is arranged on the upper and lower part of the hopper, and the guide tube goes through the two holes, and is arranged in the hopper, the hole wall of the upper and lower holes and the guide tube are sealed with each other. The utility model has the advantages of novel concept, simple structure, easy manufacture, small quantity of materials and low cost.
Description
Technical field
The utility model relates to the experiment utensil, concrete is the row pressure funnel.
Background technology
When in funnel, adding liquid in the experiment, because the influence of liquid surface tension and fluid pressure is stopped up the neck of funnel lower end, be the normal bottlenecks that claim of people, for preventing the generation of this phenomenon, people's glass bar commonly used is in test made water conservancy diversion, with liquid pouring on glass bar, flow in the following utensil slowly downwards along it, it is slower and time-consuming doing one like this, efficient is not high naturally, the 2nd, on glass gluing stayed certain quantity of fluid, and this has increased certain error undoubtedly concerning quantitative requirement is tested quite accurately.
Summary of the invention
The purpose of this utility model is in order to solve the problem that bottleneck easily takes place funnel, and the row pressure funnel that provides.
The technical scheme that adopts:
The row pressure funnel comprises funnel, conduit, and the upper and lower part of described funnel is provided with a hole respectively, and conduit successively wears two holes, and conduit is arranged in funnel, seals between the hole wall in upper and lower hole and the conduit.
The utility model is novel, and is simple in structure, makes easily, and materials are few, and are with low cost.
Description of drawings
Fig. 1 is the utility model example structure scheme drawing.
The specific embodiment
Embodiment
The row pressure funnel comprises funnel 1, conduit 2, and the upper and lower part of described funnel 1 is provided with a hole 3,4 respectively, conduit 2 successively wears two holes 3,4, conduit 2 is arranged in funnel 1, sealing between the hole wall in upper and lower hole 3,4 and the conduit 2, placement one flask 5 below funnel 1.
