Embodiment 1

[0022] refer to figure 1 and figure 2 , a two-way measuring turbine flowmeter, including a housing 1, a metering chamber 2, an impeller 3, a magnetoelectric induction converter, an amplifying rectifier 4 and a display instrument 5, a through hole is provided at the center of the housing 1, and the two sides of the housing 1 There are flanges with through holes at the ends respectively, which are used to connect with the pipeline to be tested. The metering chamber 2 is set at the center of the shell. The rotational speed of 3 is converted into a corresponding electrical signal, the coil 6 is installed on the housing 1 and aligned with the magnetic steel 7, the magnetoelectric induction converter is connected to the signal of the amplifying rectifier 4, and the amplifying rectifier 4 is connected to the display instrument 5;

[0023] The impeller 3 includes an impeller main body 31, blades 32, a first rotating shaft 33 and a second rotating shaft 34, wherein the impeller main ...

Embodiment 2

[0027] On the basis of the embodiment, in order to avoid the direct impact of the water flow (medium flow) on the bearing, a circular arched bearing shield 37 is provided above the bearing seat, and plays a role in draining the water flow (medium flow).

Embodiment 3

[0029] The difference from Embodiment 1 is that the connection end of the housing 1 is processed with internal or external threads to adapt to flanges of different specifications. According to the different specifications of the flanges required by different pipe diameters, an appropriate one can be selected. The standard flange is threaded, that is to say, the main body of the flowmeter remains unchanged, and the interface flange can be adjusted according to needs, and the product has strong adaptability. Turbine flowmeters generally have small calibers, and it is difficult to buy more than DN200. Even if they can be bought, the price is not low, and the present invention saves costs.

Abstract

The invention discloses a two-way measuring turbine flowmeter comprising a casing, a measuring cavity, an impeller, a magnetoelectric induction converter, an amplifying rectifier and a display instrument, wherein the impeller comprises an impeller body, blades, a first rotating shaft and a second rotating shaft; the impeller body is a cylinder with a blind hole for receiving magnetic steel in thecenter, a sealed cover plate is provided on the blind hole, there are a plurality of long blades arranged vertical to and symmetrically distributed on the impeller body; the first rotating shaft is thread-connected to the impeller body, the second rotating shaft is thread-connected to the sealing cover plate, and the impeller is installed vertically to the measuring cavity. The invention can realize two-way measurement, the error of the two-way measurement is small at the same time due to the symmetrical distribution of the impellers, the connecting end of the casing is processed into a threadform, and flanges of a suitable specification can be selected for threaded connection according to the different specifications of the flanges required for different pipe diameters, so that the product adaptability is strong and the cost is saved.

Description

technical field [0001] The invention relates to the field of flow testing, in particular to a bidirectional measuring turbine flowmeter. Background technique [0002] In drilling and cementing construction operations, the turbine flowmeter does not have high requirements on the construction environment and is very suitable for field operations. However, it has been found in production practice that since the impeller of the existing turbine flowmeter is composed of helical blades, the helical blades will only rotate when the medium flows in the opposite direction and impacts the blades, and the medium cannot rotate when it flows in the opposite direction. Therefore, only one-way measurement can be performed. [0003] Chinese patent CN 105973317 A discloses a two-way metering vortex flowmeter, which includes a measuring tube body, a vortex generator, a flow sensor A, a flow sensor B and a flow totalizer. The vortex generator is installed in the measuring The middle part of ...
