Description

Metal tube float flowmeter

Technical Field

The invention relates to the technical field of flowmeters, in particular to a metal tube float flowmeter.

Background

The flowmeter, defined by the national committee on the science and technology nomenclature as: meters that indicate the measured flow rate and/or the total amount of fluid in a selected time interval. Simply a meter for measuring the flow of fluid in a pipe or open channel.

When the pressure of fluid passing through the metal tube float flowmeter is unstable, the float in the measuring tube of the flowmeter can generate a bouncing phenomenon, and the bouncing phenomenon is transmitted to the pointer, so that the pointer continuously swings, the flow indication is unstable, and even a scale value cannot be read at all to determine an instantaneous flow value.

In order to solve the problems, a metal tube float flowmeter is provided in chinese patent No. CN 209166539U. In the prior art, when the pressure of fluid passing through a metal tube float flowmeter is unstable, the float in a measuring tube of the flowmeter can generate a jumping phenomenon, and even a scale value can not be read at all to determine an instantaneous flow numerical value. In order to solve the problems, the technical scheme is as follows: including casing, the indicator and the float of being connected with the casing, the casing is inside to be equipped with the toper and to measure the room, and the float is located the toper and measures indoor portion and along with the big or small fluctuation of flow, the shell includes entry flange and outlet flange entry flange department detachably installs the rectifier, the circumference equipartition has a plurality of rectification round holes on the rectifier. The inlet flange is detachably provided with the rectifier, so that fluid entering the flowmeter can be rectified firstly and uniformly enters the flowmeter, the up-and-down oscillation of the floater caused by the sudden change of the fluid pressure is avoided, and the effect of stabilizing the reading is achieved.

The above prior art solutions have the following drawbacks: set up the rectification round hole through having seted up on the rectifier, the inside speed of restriction outside water entering flowmeter to reduce the range of variation of water, but when the inside water of flowmeter is the same with outside water height, the frequency of change of the inside water of flowmeter will become with outside the same, and the float still can be the upper and lower vibrations of high frequency, and measurement of efficiency is low. To this end, we propose a metal tube float flow meter.

Advantageous effects

The invention provides a metal tube float flowmeter. The method has the following beneficial effects:

(1) when the metal tube float flowmeter is used, an external water tube is communicated with two ends of the body, an external water source enters the inside of the water containing frame, because of the principle of the communicating vessel, the height of the water inside the water receiving frame is the same as that of the water outside, when the floating plate is contacted with the water, the floating plate can float on the water surface, and the floating plate is fixedly arranged on the scale rod, therefore, the scale rod can move upwards, people can see the scales on the scale rod to know the water flow in the body, and because the water containing frame is positioned in the water, therefore, when the water flow is unstable due to unstable external pressure, the pressure inside the water containing frame is also unstable, and receive fixed mounting on the water frame and have the rubber lid, avoid receiving the inside pressure of water frame the same with external pressure, make and receive the inside pressure of water frame and be in a stable state, so the scale bar can not be at will beat, has reached the effect that improves measurement of efficiency.

(2) This tubular metal resonator float flowmeter, when using, because the rubber lid is the material, so the rubber lid has certain elasticity, when receiving the inside water pressure of water frame and change, the rubber lid can carry out slight change along with water pressure, so when receiving the inside entering water of water frame, it can change to receive the inside pressure of water frame, so the rubber lid can outwards expand, receive the inside pressure of water frame and can squeeze water, make water can not wave at will, the effect of measured stability has been reached.

(3) This tubular metal resonator float flowmeter, when using, because the air vent is seted up on the controller, and the inside of air vent is provided with the cock stem, give sealed the top of air vent through the cock stem and live, make the inside pressure of receiving the water frame be in stable state, and under the condition of difference, the flow of the inside rivers of body is different, so the height of the inside rivers of body is also different, open the cock stem, make and receive water frame and outside intercommunication, it is the same with the height of the inside water of body to receive the height of the inside water of water frame this moment, give the cock stem again, make the inside of receiving the water frame get back to sealed state again, the condition that the height of the inside water of avoiding receiving the water frame and the inside water of body highly do takes place, the effect that has improved the measurement precision has been reached.
