Abstract

The invention discloses a gas proportional valve. The gas proportional valve comprises a main valve body, a first regulating valve and a second regulating valve. A gas inlet, a gas outlet and a gas storage chamber communicating with the gas inlet are formed in the main valve body. The first regulating valve is installed in the gas storage chamber. The first regulating valve comprises a first valvebody and an opening degree regulating assembly. An inner chamber of the first valve body is divided into a first chamber and a second chamber by the opening degree regulating assembly. The first chamber communicates with the gas outlet and communicates with the gas storage chamber through a first gas port formed in the first valve body. The opening degree of the first gas port is regulated by theopening degree regulating assembly according to the quantity of gas entering the second chamber. The second regulating valve can switch between the gas supply state, the gas exhaust state and the keeping state by changing the input electric current. According to the gas proportional valve, because the first regulating valve and the second regulating valve are used in combination, the state of thesecond regulating valve is unceasingly regulated according to contrast between the pressure of the gas outlet and the required pressure so as to enable the pressure of the gas outlet to reach the required pressure, and the gas proportional valve can achieve self-adaptive regulation during installation.

Description

technical field [0001] The invention relates to the technical field of gas appliances, in particular to a gas proportional valve. Background technique [0002] The gas proportional valve is the core control part of the gas appliance. Through the pressure regulation and voltage stabilization function of the gas proportional valve, the output pressure can be stabilized under the pressure fluctuation of the gas inlet channel. For gas water heaters, the water temperature can be kept constant. The flow characteristic of the current gas proportional valve is determined by its structure. During the installation process of the gas proportional valve, the staff needs to manually adjust it, which cannot realize self-adaptive adjustment and is inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gas proportional valve, which has self-adaptive adjustment ability during installation and does not require manu...
