Abstract

The utility model discloses a flowmeter with the stationary measuring chamber, mainly comprising a water feeding conduit, an outer stationary measuring chamber, a sieve tube, a throttle baffle plate, a liquid level display, etc. When the liquid passes through the flowmeter, the flow of the liquid can be directly read according to the liquid level and the diameter of the throttle baffle plate. The utility model has the advantages of simple structure and rapid and accurate measurement, which is particularly suitable for measuring the flow in the water feeding, oil transportation, etc in the oil field.

Description

Flowmeter with stationary measuring chamber

The utility model relates to a kind of liquid flowmeter.

In field produces or other industry, usually need to measure fluid flow.For example in oil-field flooding, need measurement line water delivering orifice flow during well-flushing, when proofreading and correct down-hole 107 type flowmeters, also need to measure the water yield of its water delivering orifice.And the metering method that adopts at present is the container with a known volume, allow fluid to be measured flow in this container, and write down liquid and be full of the needed time of this container, then by calculating flow, or within a certain period of time, determine its flow by the liquid volume in the measuring vessel.The shortcoming of this method is, both expends time in during measurement, and the data that obtain are inaccurate again, thereby production is brought adverse effect.

The purpose of this utility model is to design a kind of simple in structure, measures liquid flowmeter soon and accurately.

The pot type flowmeter is made up of parts such as urceolus, screen casing, throttle flap, stream interface elevation indicators.When liquid enters the pot type flowmeter, by the throttle flap throttling, a liquid is discharged from pot type flowmeter flowing water mouth, and another part liquid raises tank level, according to liquid level and throttle flap bore, utilize the Bernoulli equation on the hydraulics can calculate fluid flow.In the utility model, all on throttle flap, mark for the fluid flow of the pairing liquid level of throttle flap of each bore.So can read each flow constantly from throttle flap.The bore of throttle flap can be selected according to the size of flow.

Advantage of the present utility model is: the pot type meter readings is quick, accurate, simple in structure, cost is low.As long as having general welding gear can make.

Accompanying drawing is a pot type flowmeter structure synoptic diagram.Comprising penstock (1), outer jar (2), screen casing (3), O-ring seal (4), throttle flap (5), bolt (6), nut (7), liquid level display parts such as (8).Outer jar (2) are made by steel plate or other material.On the tube wall of screen casing (3) some apertures are arranged, when liquid enters flowmeter, at first enter screen casing, outside aperture enters jar, the effect of screen casing is to make outer jar liquid level to keep stable then.Throttle flap is made by irony or other materials, and flow value (with the liquid level correspondence) is arranged on the throttle flap.Liquid level display (8) is made by glass or other transparent material, and the altitude scale value is arranged on the display.The liquid level display communicates with outer pot bottom.

Claims

1, a kind of pot type flowmeter is made up of water inlet pipe (1), outer jar (2), screen casing (3), throttling plate washer (5) and liquid level display (8) etc., it is characterized in that:

A, screen casing (3) be jar (2) inside outside, and some apertures are arranged on the screen casing;

B, water inlet pipe (1) pass outer jar and directly communicate with screen casing;

C, throttling plate washer (5) are located at outer jar bottom and an outer jar water delivering orifice joins, and the throttling plate washer is marked with the flow value corresponding to liquid level, and throttling plate washer bore can be selected according to flow range;

D, liquid level display (8) communicate with outer pot bottom, and indicate scale value;

2, flowmeter according to claim 1 is characterized in that screen casing (3) is to be made by irony or other material;

3, flowmeter according to claim 1 is characterized in that throttling plate washer (5) is to be made by irony or other material.
