Abstract
The utility model discloses a new type of flow meter, including a meter cylinder, an inlet, an outlet, a piston, springs, adjusting screws, etc. The cylinder of the flow meter is of transparent glass tube, with evenly opened slits in the side. A water outlet pipe is connected to the outside of the slits. A piston is arranged in the tube body and connected by a spring to an adjustment screw. The adjustment screw is installed in the cylinder end, and is used for level, upright, and inverted quasi-zero time measurement respectively. When the liquid flows into the cylinder, the liquid generates pressure to the piston to move the piston. At the same time, the liquid flows out from the slit. Therefore, the liquid inflow is equal with the liquid outflow per unit time, and the piston stays in a certain position. The instantaneous flow can be read by observing the scale on the tube body. The utility model is a flow meter which has advantages of: compact design, simple structure, wide use and low price.
Description
Technical field:
The utility model relates to a kind of flowmeter, is a kind of hydraulic resistance formula flowmeter.
Background technology:
Existing flowmeter generally all has complicated structure and adds the sub-original paper of distribution, and this makes its use be restricted, and costs an arm and a leg; The better simply suspended body flowmeter of structure is then because its structural reason can only the upwards mobile fluid of measuring vertical.
Summary of the invention:
The utility model provides a kind of deft design, and is simple in structure, uses extensively cheap flowmeter.The utility model technical solution is:
A kind of novel flowmeter comprises the flowmeter cylindrical shell, water inlet, water delivering orifice, piston, spring, adjusting screw etc.
It is characterized in that: the flowmeter main body is the flowmeter cylindrical shell, and the bottom is a water inlet, and piston links to each other with adjusting screw by spring, and adjusting screw is installed in barrel tip, and water delivering orifice is arranged on the cylindrical shell.
Principle of work: behind the flow of liquid inbound traffics meter cylindrical shell cylindrical shell inner carrier is produced pressure and promote its motion, the liquid that enters simultaneously flows out from the water delivering orifice slit, when the liquid that flows in the unit interval equates with the liquid of outflow, piston rests on a certain position, just can read instantaneous delivery by the scale of observing on the cylindrical shell.
Description of drawings:
Fig. 1 is the utility model perspective structure synoptic diagram.
Among the figure: 1-flowmeter cylindrical shell; The 2-water inlet; 3-water delivering orifice (slit); The 4-piston; The 5-spring; 6-adjusting screw and 7-scale
Below in conjunction with drawings and Examples the utility model is described in further detail.
Concrete embodiment is:
A kind of novel flowmeter, main body are flowmeter cylindrical shell 1, and the bottom is a water inlet 2, and piston 4 links to each other with adjusting screw 6 by spring 5; Adjusting screw 6 is installed in cylindrical shell 1 end, and water delivering orifice (slit) 3 is arranged on the cylindrical shell 1.Behind the flow of liquid inbound traffics meter cylindrical shell cylindrical shell inner carrier is produced pressure and promote its motion, the liquid that enters simultaneously flows out from slit, when the liquid that flows in the unit interval equated with the liquid of outflow, piston rested on a certain position, just can read instantaneous delivery by the scale of observing on the cylindrical shell.
