Embodiment Construction

[0021] As shown in the figure, a stepless regulating cock valve includes a valve body 1, an air inlet, an air outlet pipe 102, and an air outlet pipe 103 are arranged on the valve body 1, and a solenoid valve 3 is installed at the air inlet, and inside the valve body 1 A cock hole 101 is provided, and a spool 2 cooperating with it is arranged inside the cock hole 101 , and the spool 2 is driven by the motor 4 installed on the valve body 1 .

[0022] The inner wall of the valve body 1 is provided with an air inlet 111 and an air inlet 112, and the valve core 2 is provided with an axially arranged central hole 201. One end of the central hole 201 is connected to the drive shaft of the motor 4 and is closed, and the other end is connected to the air inlet. connected. The valve core is roughly in the shape of a truncated cone, and two groups of air outlet holes at different heights are arranged on the peripheral surface, corresponding to the air inlet hole 111 and the air inlet ho...

Abstract

The invention discloses a steplessly adjustable electric control gas valve which comprises a valve body, a valve plug, and a motor for driving the valve plug, wherein a cock hole fitted with the valve plug is arranged in the valve body, and the inner wall of the cock hole is provided with air inlet holes; an axially-arranged center hole is arranged in the valve plug, and the circumferential surface of the valve plug is provided with at least two air outlet holes which correspond to the same air inlet hole and used for controlling the flow quantity of each section of gas flowing through the air inlet hole; the external wall surface of the valve plug at the height of the air outlet hole is provided with a vent groove which is arranged along the circumferential direction of the valve plug, the air outlet hole for controlling the maximum gas flow quantity of the air inlet hole is communicated with the vent groove, and the parts of the other air outlet holes close to the center hole are radially narrowed so as to form a gas control section. The electric control gas valve disclosed by the invention has the advantages that through setting the vent groove communicated with the air outlet hole for controlling the maximum air flow quantity of the air inlet hole on the external circumferential surface of the valve plug, the parts of the other air outlet holes close to the center hole areradially narrowed so as to form the gas control section, therefore, even if gaps exist between mechanisms, the firepower of stoves also can accurately be controlled.

Description

technical field [0001] The invention relates to a valve, in particular to a steplessly adjustable 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 has gradually developed from a mechanical type to an electronic control type, that is, the rotation of the cock has been 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 v...
