Embodiment Construction

[0038] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0039] refer to Figure 1-Figure 3 Describe the premixing device 1000 of the embodiment of the present invention. The premixing device 1000 can premix gases of different media to obtain a uniformly mixed gas mixture. For example, when the gas enters the combustion chamber of the gas equipment for combustion, the gas and air can be pre-mixed in the pre-mixing device 1000, and the gas mixed with air and gas (referred to as air-fuel gas) enters the combustion chamber for full and effective combustion. Wherein, the gas eq...

Abstract

The invention discloses a venturi tube, a premixing device and gas equipment. The venturi tube comprises a body, the body defines a gas flow channel with an air inlet and a gas nozzle, and air and gasare mixed in the gas flow channel; a flow limiting plate arranged in the gas flow channel and defines and an air port communicated with the air inlet; and a ball valve arranged on the inner wall surface of the gas flow channel in a sliding manner and used for adjusting the flow area of the air port. According to the venturi device provided by the embodiment of the invention, the flow limiting plate with the air port is arranged in the gas flow channel, and the opening degree of the air port is controlled through the ball valve, so that a better air-fuel ratio is obtained, the air-fuel ratio adjusting range is large, the universality is high, and the venturi device can meet the requirements of different load models.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a Venturi tube, a premixing device and gas equipment. Background technique [0002] The premixing device in the related art cannot effectively adjust the mixing amount of gas and air, and the combustion adjustment ratio is small, so it cannot meet the gas equipment with different load demands. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems at least to a certain extent. [0004] Therefore, the present invention proposes a Venturi tube, which has a good air-fuel ratio and strong versatility. [0005] The present invention also proposes a premixing device with the above-mentioned Venturi tube. The premixing device has good air-fuel ratio and strong versatility. [0006] The present invention also proposes a gas equipment with the above-mentioned premixing device, and the combustion efficiency of the gas ...
