Description

Electronic ignition one-key starting valve

Technical Field

The utility model belongs to the technical field of valves, and relates to an electronic ignition one-key starting valve.

Background

When the existing cooking utensils are used, a gas switch and an ignition device are often required to be matched for use. For example, the valve is opened after the small fire is ignited, and the size of the damper is adjusted, or the valve is opened first to supply gas and then the fire is ignited.

However, in the actual use process, the control mode of the step-by-step operation not only has the problem of inconvenient operation, but also is easy to cause certain potential safety hazard and even safety accidents due to misoperation. For example, after the gas pipeline is opened, the gas pipeline is not ignited in time, so that a large fire burns a person when ignition is delayed, or when a large amount of gas is discharged without ignition, safety accidents such as operator poisoning are easily caused.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in figure 1, the electronic ignition one-key starting valve comprises a valve body 1, a valve core arranged in the valve body 1, a valve rod 2, a handle and a starting switch 3 fixed on the side of the valve body 1, wherein the inner end of the valve rod 2 extends into the valve body 1 and is connected with the valve core, and the outer end of the valve rod 2 extends out of the valve body 1 and is connected with the handle.

Have the cross section on the valve rod 2 and personally submit square linkage segment, linkage segment outside cover is equipped with plectrum 4, this plectrum 4 is including being the annular cover of circle and establishing portion 6 and being located the protrusion that the 6 one side of portion was established to the cover in the stirring portion 9 of valve rod 2 lateral surface, the hole of establishing portion 6 of cover is square, then plectrum 4 cover is established after the linkage segment outside of valve rod 2 with valve rod 2 circumference is fixed, the handle can be spacing to plectrum 4's axial position after fixing the outer end of valve rod 2, avoid plectrum 4 to take place the axial float.

Starting switch 3 includes the spring, fix main part 5 in the valve body 1 outside and articulate the button in main part 5, the button is located main part 5 towards one side of plectrum 4, the button articulates in main part 5 towards the one end middle part of main part 5, one side towards plectrum 4 on the button is including the closed part 7 and the disconnection portion 8 that are located the pin joint both sides respectively, closed part 7 and disconnection portion 8 formula structure as an organic whole, under the spring action of spring, disconnection portion 8 on the button removes to main part 5 direction, and simultaneously, closed part 7 removes to the direction of keeping away from main part 5 around the pin joint, starting switch 3 is in the off-state. When the valve rod 2 rotates in the circumferential direction, the poking sheet 4 can act on the closing part 7 to drive the closing part 7 to move towards the main body 5 against the elastic force of the spring so as to enable the starting switch 3 to be in a closing state. In the embodiment, the whole starting switch 3 is obliquely fixed on one side of the valve body 1 relative to the axis of the valve rod 2, and one end of the starting switch 3 with the closing part 7 is closer to the plectrum 4 relative to the other end, so that the plectrum 4 can better act on the closing part 7 and can not influence the action of the opening part 8; the pushing sheet 4 can be provided with an arc-shaped surface at the position abutting against the key so as to reduce contact wear, and the starting switch 3 is detachably fixed on the valve body 1 through a screw serving as a fastener.

The electronic ignition one-key starting valve is installed in a gas conveying pipeline, and a starting switch 3 is connected in series in an ignition circuit and a fan power supply circuit at the same time. In a default state, the valve core is in a closed state, the poking sheet 4 is far away from the closing part 7, and the opening part 8 swings towards the main body 5 under the action of the elastic force of the spring, so that the starting switch 3 is in an opening state.

When the gas valve is used, the handle is rotated, the valve core in the valve body 1 is driven to move through the valve rod 2, the gas valve is communicated with a gas conveying pipeline, and gas is sent out from the pipeline. Meanwhile, the plectrum 4 on the valve rod 2 rotates along with the valve rod 2 synchronously, leans on and exerts the acting force on the closing part 7, drives the closing part 7 to overcome the elastic action of the spring and swing towards the main body 5 direction so as to enable the starting switch 3 to be in the closing state, and then triggers ignition and the fan is electrified to work.

Conversely, when the handle is rotated reversely, the poking sheet 4 leaves the closing part 7, and the opening part 8 and the closing part 7 are reset under the action of the elastic force of the spring and return to the initial state.

The specific embodiments described herein are merely illustrative of the spirit of the utility model. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the utility model as defined in the appended claims.
