Abstract

The utility model discloses a cutting simple ignition device, which is provided to overcome the weaknesses existing in the current ignition device that the making art of the automatic ignition device is complex, and the manufacture cost is high. The utility model comprises an ignition branch pipe which is located on one side of a cutting mixture gas pipe and is communicated with the cutting mixture gas pipe, an ignition nozzle on one end of the ignition branch pipe and relative to a cutting gas-jet, a sparking head near to the end of the ignition nozzle, a wire for connecting the sparking head and an electronic fire interrupter maker, and a hand switch valve arranged on the channel of the ignition branch pipe. Due to the hand switch valve on the cutting to open and close the ignition branch pipe channel, the hand switch valve is turned on by hands at the same time of opening a mixture gas valve, and simultaneously the electronic fire interrupter maker is operated to enable the sparking head to ignite, thereby igniting the mixture gas on the ignition nozzle, and the flame ejected ignites the gas which is ejected from a flaming gas-jet. The utility model uses the current cheap hand switch valve which is just installed on the ignition branch pipe, which plays roles of safety and convenience when in using, and has simple making and low making cost.

Description

The simple and easy igniter of cutting torch

Technical field

The utility model is mounted on the cutting torch, is used to the device of cutting torch igniting.

Background technology

The acetylene gas cutting torch when carrying out gas welding or gas cutting, open the air mixture valve after, combustion gas is lighted operation from valve ejection.Lighting the air mixture at valve place, generally is to light with match, wants a hand to take cutting torch also will take matchbox simultaneously during operation, and the another hand is taken splint to wipe combustion and delivered to valve.Very inconvenient with above-mentioned sparking mode, and splint is short and small, when directly holding the splint igniting of firing with hand, burns immediately from the combustion gas of valve ejection, does not note slightly just being burnt easily; Also have in wet weather and use match, drawing not feasible inconvenience more because of it makes moist to wipe easily.If use the lighter igniting, flame is too closely also dangerous from hand during because of igniting.

A kind of patent No. is 200520087309, the patent that name is called " cutting torch automatic ignition device " has solved the problems referred to above, it is a side at the cutting torch mixture pipe, be provided with the igniting arm that communicates with mixture pipe, the valve of its ignition tip subtend cutting torch, the igniting arm is provided with and opens and closes a tube passage and push the interlock button of sparking, electronic lighter is connected by the rotor of lead with the ignition tip place, the operations linkage button, rotor sparking when opening a tube passage, realize the automatic igniting of cutting torch, safe in utilization, convenient, solved the long-term indeterminable problem of people.The weak point of above-mentioned automatic ignition device is, automatic ignition section process for machining and manufacturing complexity, manufacturing cost height.

The utility model content

Technical problem to be solved in the utility model is, overcomes existing automatic ignition device complex manufacturing technology, and the shortcoming that manufacturing cost is high provides a kind of cutting torch simple and easy igniter.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the cutting torch igniter is included in cutting torch mixture pipe one side, the igniting arm that communicates with mixture pipe, the ignition tip of igniting Zhi Guanduan subtend cutting torch valve, the rotor of near point nozzles termination, and the lead that connects rotor and electronic lighter, on an igniting tube passage, be provided with the hand switch valve.

The utility model also has following technical characterictic:

Described igniting arm is for presenting the bend pipe of bow action to the oxygen hose direction on cutting torch top;

Described fire maker is installed in an end of the nearly mixing air valve on the cutting torch mixture pipe.

Advantage of the present utility model and good effect are, because what open and close igniting arm passage on the cutting torch is the hand switch valve, only with hand is turned on the hand switch valve when opening the mixing air valve, mist leads to valve and ignition tip, operate electronic lighter simultaneously and make the rotor sparking, the mist at ignition tip place is lighted, and the ignite combustion gas of valve ejection of the flame of ejection is finished and closed the hand switch valve after the igniting and get final product.What above-mentioned igniter was used is existing cheap hand switch valve, is installed on the tube passage of lighting a fire as long as buy, and can play safety, effect easily during use equally, makes simply low cost of manufacture.

Description of drawings

Fig. 1 looks schematic diagram for master of the present utility model;

Fig. 2 is that the A of Fig. 1 is to partial schematic diagram.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, igniter comprises mixture pipe 2 one sides of cutting torch, the igniting arm 4 that communicates with mixture pipe 2, subtend cutting torch valve 1 place, termination at igniting arm 4 is provided with ignition tip 3, lead 5 usefulness clamps 5.1 are fixing along igniting arm 4, and the rotor 3.1 that will be installed in electronic lighter 7 on the cutting torch and near point nozzles 3 terminations connects, on the passage of igniting arm 4, be provided with existing common combustion gas hand switch valve 6 (referring to Fig. 2).

When lighting a fire for cutting tool, when opening mixing air valve 8, only with hand is turned on hand switch valve 6, and mist enters cutting torch valve 1 and ignition tip 3 by the passage of mixture pipe 2 and igniting arm 4; Operation electronic lighter 7 makes rotor 3.1 sparking by lead 5, and the mist at ignition tip 3 places is lighted, and the ignite combustion gas of valve ejection of the flame of ejection is closed hand switch valve 6 after igniting is finished, and fiery arm 4 stops air inlet.Above-mentioned igniter compared with prior art, and is simple in structure, uses safety, reliable, convenient too.

Igniting arm 4 can be existing straight tube, and in order to make also be convenient to operation hand switch valve 6 on the igniting arm 4 of hand by cutting torch, described igniting arm 4 is arc bend pipe upwards for the oxygen hose direction to cutting torch top.

Be operation for convenience equally, described electronic lighter 7 is installed on the position of nearly mixing air valve 8 one sides on the cutting torch mixture pipe 2.
