Abstract
The utility model has the advantages that function is accurate and wearable, a float rides up and down stably without swinging and friction, and a staff and reading are permanently clear so that the flow quantity in the measured pipeline is precise, use is easy, and service life is long. The utility model is composed of an upper retaining ring, a conical tube, the float, a lower retaining ring, a seal ring in O-shaped, loose joint nuts, a connection tube, a flange, and a guide bar. The utility model is characterized in that the guide bar is arranged in the middle of the conical tube, the float of the guide bar reciprocates following the guide bar, and the staff and indicated value is permanent.
Description
The utility model is to be installed on liquid pipeline system, the instrument of fluid flow in the sealing measuring channel.
At present, upper and lower the moving of " heart " parts of " plastics conical tube spinner-type flowmeter "---float had no precedent to follow, double swerve, inhale with the conical tube tube wall always and hit friction, cause the fluffing of conical tube inwall, the transparency of tube wall is descended, and it is bigger promptly to influence the liquid flow mearuement error, again clear reading has been produced obstruction; In addition, the technology of scale that the conical tube outer wall is annotated is moved back mistake easily for printing, causes continuous data not have according to shining, and has lost the effect of measurement instrument.
The utility model purpose: inhale to hit and rub and drawback that scale moves back mistake easily designs for eliminating float and tube wall.
The utility model adopts the conical tube center that upright guide rod is set, and guide rod hole is beaten at the float center, and seals in guide rod, and float can upper and lowerly at the conical tube center steadily be moved all the time, produces double swerve and tube wall never again and inhales the situation of hitting; Again, change plastic tube outer wall scale and indicating value into the quarter casting by printing, the indicating value on the scale just can go up standard and demarcate separately, so just can accomplish that flow metering is accurate and scale is forever clear, come into plain view.
Fig. 1 is the utility model embodiment 1.
Fig. 2 is the utility model embodiment 2.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
Among the figure: go up ring washer 1, conical tube 2, float 3, following ring washer 4, " O " RunddichtringO 5, loose joint nut 6, adapter 7, scale 8, flange 9, guide rod 10.
In vertical transparent plastics conical tube 2, up and down movably float 3 centers by being fixed on the guide rod 10 of ring washer 1 and following ring washer 4, when liquid was flowed through plastics conical tube 2 from descending, float 3 was followed on the guide rod 10 and is moved producing under the effect of pressure reduction between liquid buoyancy and the upstream and downstream.When the gravity of float 3 and buoyancy, when viscous force three makes a concerted effort to equate, just show that the novel amount of liquid of this reality of flowing through is the height that float 3 rises, be that flow and circulation area exist certain proportionate relationship, this has just been determined the flow value of measured flux by float 3 and the opposite position of carving casting scale 8 on the pipe outer wall.The utility model embodiment 2 is that the two ends of conical tube connect with flange.
The utlity model has characteristics such as liquid flow mearuement is accurate, easy to use, firm and durable.
Claims (3)
1, the accurate durable spinner-type flowmeter of a kind of plastic tube is made up of last ring washer 1, conical tube 2, float 3, following ring washer 4, " O " RunddichtringO 5, loose joint nut 6, adapter 7, flange 9, guide rod 10; Its feature: the conical tube center is provided with upright guide rod 10, and float 3 is followed guide rod 10 and moved up and down, and scale 8 and indicating value are permanent.
2, flowmeter according to claim 1, its feature: float, guide rod are made with metal, and other each parts are plastics.
