Embodiment Construction

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening ele...

Abstract

The invention relates to a fuel gas proportional valve comprising a valve body, a valve assembly, a valve cover, a first driving piece, a magnetic conductive piece and an electromagnetic coil assemblyarranged around the magnetic conductive piece. The valve assembly is mounted inside the valve body, and the valve cover is mounted outside the valve body. The electromagnetic coil assembly is mountedin the valve cover, the magnetic conductive piece is connected with the valve assembly, and the first driving piece is used for driving the electromagnetic coil assembly to move away from or close tothe valve body. The first driving piece drives the electromagnetic coil assembly to move away from or close to the valve body, thus the first driving piece can adjust the strength of a magnetic fieldgenerated by the electromagnetic coil assembly, then the acting force of the magnetic conductive piece on the valve assembly is adjusted, and a gap between the valve assembly and the valve body is changed, so that the fuel gas proportional valve gets the appropriate P2H value, fluctuation of the P2H value is avoided, and the comfort of using of users is improved.

Description

technical field [0001] The invention relates to a gas valve, in particular to a gas proportional valve. Background technique [0002] The gas proportional valve is the core component of the constant temperature gas water heater. Its main function is to stabilize the output pressure of the gas proportional valve and adjust the output pressure of the gas proportional valve according to the input current. In the performance test of gas proportional valve, P 2L (The gas proportional valve is in the low load working state, that is, the outlet pressure when the current is small) and P 2H (The outlet pressure of the gas proportional valve under high load working condition, that is, when the current is large) are two very important parameters. The P of the traditional gas proportional valve 2H The value is determined by the magnetic field generated by the solenoid coil. However, the electromagnetic coil is affected by the fluctuation of the winding process and the assembly error...
