Embodiment Construction

[0023] Such as Figure 1~4 As shown, a three-gas universal electric control gas valve includes a valve body 1, a valve core 2 and a motor (not shown in the figure) that drives the valve core, an air inlet (not shown in the figure) on the valve body 1, The air outlet 101 and the cock hole 102 matched with the valve core 2, and the air inlet end can be connected with an electric valve for controlling the air intake. The number of gas outlets 101 can be arbitrary, and can be three or two as used in a general cooker. In this embodiment, three gas outlets are selected to control the outer ring fire, the inner ring fire and the middle ring fire of the cooker burner respectively.

[0024] There are three air paths between each air outlet and the cock hole 102 , namely the first air path 111 , the third air path 113 and the second air path 112 for controlling the maximum air flow, the intermediate air flow and the minimum air flow. The starting ends of the three gas paths meet the si...

Abstract

The invention discloses a universal electronic-control gas valve for three gases, which comprises a valve body and a valve core, wherein the valve body is provided with a gas inlet, a gas outlet and a plug hole matched with the valve core; three gas circuits respectively controlling gas flows of three sections of the same gas outlet are arranged in the valve body; the starting ends of the three gas circuits are gathered in the plug hole; three branch gas inlets are formed on the inner wall of the plug hole; a first adjusting hole having a built-in adjusting bolt is arranged on the valve body;the second gas circuit and the third gas circuit are merged at the first adjusting hole to form a sharing section communicated with the gas outlet; the top of the first bolt is provided with a secondadjusting hole having a built-in second bolt and the interior of the first bolt is provided with a fourth gas circuit passing through the second adjusting hole; and one end of the fourth gas circuit is communicated with the third gas circuit while the other end of the fourth gas circuit is communicated with the sharing section. The electronic-control gas valve provided by the invention can adjustthe middle gas flow and the minimum gas flow through the two adjusting bolts, for ensuring that the gas meets the demands on middle firepower and the minimum firepower. The electronic-control gas valve is fit for three gases.

Description

technical field [0001] The invention relates to a valve, in particular to a three-gas universal electric control gas valve. Background technique [0002] Existing gas cookers all control the size of the firepower through a cock valve, and the principle is to control the amount of gas flowing through the cock valve. In order to control the firepower more accurately, the existing cock valve is gradually developed from a mechanical type to an electric control type, that is, the rotation of the cock is changed from manual control to stepping motor drive. [0003] The electric control gas valve adjusts the flow of gas through the stepping motor to rotate the valve core. The existing electric control valve can only be adjusted in sections, such as three sections, five sections, six sections, etc., or use the same mechanism as the mechanical valve. The principle is adjusted. For example, Chinese patent 200720112000.6 discloses an electronically controlled gas control valve, which...
