背景技术： Background technique:

现有家用燃气具使用的燃气比例阀通常是采用电控阀来控制：燃气比例阀的气量大小是按比例阀上的电控阀电流大小来控制。当燃气具同时采用燃气比例阀和风机配合燃烧时，由于燃气比例阀和风机各自的响应速度不一样，在调节过程中燃气和空气的配比会偏离线性状态，因而容易出现黄火、离焰、回火、噪声等不稳定状态，影响燃气具的使用。为克服这些缺陷，对燃气比例阀进行了研制。The gas proportional valve used in existing household gas appliances is usually controlled by an electric control valve: the gas volume of the gas proportional valve is controlled according to the current of the electric control valve on the proportional valve. When a gas appliance is combusted with a gas proportional valve and a fan at the same time, due to the different response speeds of the gas proportional valve and the fan, the ratio of gas and air will deviate from the linear state during the adjustment process, which is prone to yellow flames and flames , tempering, noise and other unstable states affect the use of gas appliances. In order to overcome these defects, a gas proportional valve has been developed.

本实用新型与现有技术相比其有益效果是：Compared with the prior art, the utility model has the following beneficial effects:

1、由于本实用新型采用以空气源调节调压腔压力来控制比例阀的气量大小的结构，故它不仅有普通比例阀的比例调节气量功能，而且当燃气具同时采用本比例阀和风机配合燃烧时，以风机后的空气为空气源时，比例阀和风机响应速度保持一致，能够有效地调节燃气和空气的配比，使燃气和空气的配比为线性状态，满足用户正常使用燃气具。1. Since the utility model adopts the structure that the air source is used to adjust the pressure of the pressure regulating chamber to control the air volume of the proportional valve, it not only has the function of adjusting the air volume of the ordinary proportional valve, but also uses the proportional valve and the fan to cooperate with the gas appliance.

The valve body 8 is provided with an air intake nozzle 9 communicating with the air source, and the spring 6 is in the pressure regulating chamber 7 and connected with the pressure regulating valve body 8 and the diaphragm 4 . When the air pressure in the pressure regulating chamber 7 increases, the valve 5 moves toward the outlet chamber 3, the channel area between the valve 5 and the proportional valve body 1 increases, and the gas flow increases; otherwise, the air pressure in the pressure regulating chamber 7 decreases. Hours, the valve 5 moves toward the intake chamber 2, the channel area between the valve 5 and the proportional valve body 1 decreases, and the gas flow decreases.
