Problems solved by technology

But this firepower regulating device can't change the rotation angle of valve body in a wide range, and its firepower adjustment is from closed state to ignition state (maximum firepower position) and then to minimum fire state, and the total stroke of the angle of its valve body rotation is 170 ° Left and right, from the off state to the ignition state is usually 90°, 90° to 170° is the adjustment range from the maximum firepower to the minimum firepower, the adjustment angle range is only 80°, the real effective adjustment range is only 45°, the firepower varies The gradient is small, and the change gradient of the firepower adjustment is very uneven, which will cause the firepower adjustment to be relatively concentrated and difficult to control
In addition, the current cookers on the market use ordinary plunger valves, and ordinary plunger valves cannot achieve linear adjustment, the adjustable range is very small, and most of them are ineffective adjustment stages. For details, see the ordinary valve body flow curve ( attached Figure 11 ), the reason is that the flow control section of the ordinary valve body is realized by the change of the intersection section of two circular holes, and this method cannot realize the linear control of flow

Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] Such as Figure 1-11 Shown is a preferred embodiment of the present invention.

[0038] The regulating valve capable of linearly adjusting the firepower of the gas stove of the present invention includes a valve body 1, the valve body 1 is formed by connecting a front fixed cover 11 and a rear sealing cover 12, and a valve cavity 10 is formed inside it, and the front fixed cover 11 is provided with One air inlet 2 and three side-by-side air outlets 3, this structural arrangement is conducive to the rational layout of the inlet and outlet air pipes of the cooker of the present invention on the chassis, wherein the air inlet 2 connected with the gas source and the valve cavity 10 connected, all the outlets 31 of the air outlets 3 on the inner wall of the valve cavity are located on the same plane, in order to further effectively reduce t...

Abstract

The invention relates to an adjusting valve capable of adjusting fire linearly. The adjusting valve comprises a valve body; the valve body is provided with a valve cavity defined by a valve wall; the valve wall is provided with an air inlet hole and at least one air outlet hole; the adjusting valve is characterized in that outlets of all the air outlet holes formed in the inner wall of the valve cavity are arranged in the same plane, and a moving part is matched with the outlet of each air outlet hole in a sealing way; each moving part is provided with a strip-shaped hole communicated with the valve cavity of the valve body; when the moving parts slide, the strip-shaped holes synchronously slide relative to the outlets of the air outlet holes formed in the inner wall of the valve cavity along the striking direction of the strip-shaped holes, so that the gas flow rate in the corresponding air outlet holes can gradually change; furthermore, each moving part is also connected with a driving device. Compared with the prior art, the adjusting valve has the advantages that the adjusting valve is simple in structure; when the adjusting valve is used, the driving devices are only needed to be rotated, and the valve body can slide in the plane formed by the outlets on the inner wall of the valve cavity by the strip-shaped holes formed in the moving parts, so that the sectional areas of the outlets on the inner wall of the valve cavity can be changed, and the aim of controlling the flow rate linearly can be achieved.

Description

technical field [0001] The invention belongs to the technical field of gas equipment, and in particular relates to a regulating valve capable of linearly regulating firepower. Background technique [0002] The fire power regulating device of the gas stove is the main structural part of the gas stove. The gas passes through the valve, and the ignition device ignites the gas emerging from the fire eye of the burner to achieve the purpose of cooking food. Existing household gas stove burners generally have a plurality of fire dividers, and the burner respectively leads out the injection tubes which are not connected to each other. size. Existing fire power adjusting device usually comprises valve body, valve core, valve shaft, valve seat, and valve core and valve body are movable assembly, and the nozzle that can spray gas is arranged on valve body. Its structure basically drills vent holes of different sizes at different positions on the cone of the valve core. By rotating t...
