Problems solved by technology

Although this airfoil flowmeter adopts an airfoil structure, it must have a certain elevation angle to convert the flow value according to the mechanical principle. It does not take into account that the installation elevation angle of the flowmeter itself has a great disturbance effect on the flow field, and the measurement accuracy It is greatly affected by the elevation angle of the force sensor and the airfoil sheet

Embodiment Construction

[0019] In order to enhance the understanding of the present invention, the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0020] Such as Figure 1-5 As shown, the present invention is a diversion type airfoil flow measuring device, including the airfoil flow measuring device body, the airfoil flow measuring device body is composed of a primary device and a secondary device, and the primary device includes an airfoil sheet 1 and a positioning bracket 2. The airfoil thin plate 1 is fixed on the positioning bracket 2. There are threads on the outside of the positioning bracket and screwed on the flow channel in the wall of the air distributor for easy disassembly. The material of the bracket is preferably stainless steel, and the flow channel is between the upper and lower flow channel w...

Abstract

The invention relates to a flow guiding type wing-shaped flow measuring device, which comprises a wing-shaped flow measuring device body, wherein the wing-shaped flow measuring device body consists ofa primary device and a secondary device; the primary device comprises a wing-shaped thin plate and a positioning bracket; the wing-shaped thin plate is fixed on the positioning bracket; a full-pressure taking pipe and a static-pressure taking pipe penetrate through the wing-shaped thin plate and the positioning bracket and are connected with a wind pressure transmitter of the secondary device; adata output interface is arranged on the wind pressure transmitter; and a data receiving interface is arranged on a controller. The flow guiding type wing-shaped flow measuring device is simple in structure and reasonable in design, can accurately measure the flow of wind, and is convenient to adjust the wind quantity in the cabin in time.

Description

technical field [0001] The invention relates to the technical field of flow measurement, in particular to a diversion type airfoil flow measurement device used in a marine air distributor. Background technique [0002] Ship air-conditioning systems generally use air distributors as the ventilation terminal. High-end air distributors have the function of automatically adjusting the air volume. Accurate measurement of air supply volume is an important prerequisite for improving the temperature control accuracy of high-end air distributors and improving the comfort of the air-conditioning system. Air distributor flowmeters are divided into pipeline flowmeters and flowmeters in the flow channel. Commonly used pipeline flowmeters are cross-shaped flowmeters. Pitot tube principle - Bitoba flowmeter, etc. However, due to the limitation of working principle and structural design, the current flowmeter has high requirements on the temperature of the measured medium, flow state and o...
