Description

Magnetic suction pressing type igniter for handheld acetylene cutting torch

Technical Field

The utility model belongs to the technical field of metal manual cutting, and particularly relates to a magnetic suction pressing type igniter for a handheld acetylene cutting torch.

Background

The acetylene cutting torch is a common hand tool for metal manual cutting, the acetylene welding torch is a common hand tool for metal manual welding, baking heating and burning, the liquefied gas flame gun is a common hand tool for metal and nonmetal object manual welding, baking heating and burning, the acetylene cutting torch and the liquefied gas flame gun are wide in application range in production and life, are universal general tools and have very wide usability in related industrial operations of petroleum exploration, engineering technology, oil field construction, oil and gas extraction and transportation, finished product refining, equipment manufacturing, capital construction and the like of a petroleum industry chain.

For convenience of description, these heat source tools are hereinafter collectively referred to as the most commonly used "acetylene cutting torch".

The hand-held igniter in the prior art is basically in a pistol type electronic pulse ignition mode, is larger in size than a common igniter, inconvenient to carry and much higher in price than the common igniter after being damaged, so that the ignition mode and the appliance are almost ignited by the common igniter in actual production and life. For convenience of description, it will be referred to hereinafter collectively. The most commonly used ignition operation process of the lighter is as follows: the gun handle is held in one hand and the lighter is operated in the other hand. When one hand holding the gun handle is in an ignition process, the thumb and the index finger are separated to be matched with each other, the gas knob valve on the gun handle is unscrewed, so that gas is sprayed out of the gas nozzle, meanwhile, the other hand operates the lighter to be aligned with the gas nozzle for ignition, and the gas is ignited.

In a short operation process, due to the decomposition of several steps, operational inconvenience and safety risk factors exist.

The operation is inconvenient.

Before ignition, firstly removing the welder gloves, drawing out the portable lighter from the pocket, separating a thumb and a forefinger by a hand holding the handle to unscrew an acetylene switch knob of the acetylene cutting torch, and operating the lighter by the other hand to aim at a cutting nozzle of the acetylene cutting torch for ignition; the acetylene switch knob of the acetylene cutting torch is synchronously unscrewed by holding the handle. After the flame is ignited, in order to quickly maintain the stability of the flame and reduce the dense soot pollution formed by incomplete combustion of the flame, the air-fuel ratio of the flame combustion must be controlled, and a hand holding an igniter also needs to quickly control an oxygen mixing knob of an acetylene cutting torch to adjust the oxygen supply and ensure the proper oxygen-fuel ratio. After the flame is stabilized, the other hand puts back the lighter, wears welder's gloves, and both hands operate the acetylene cutting torch and carry out normal operation. Although the ignition operation process only lasts for about ten seconds, the complex and fine operation of coordination and coordination of two hands and single-hand and double-action and the process of repeatedly taking off and wearing welder gloves are involved, and the ignition operation process has the operation characteristics of small operation and great complexity.

② there is a safety risk of operation.

There are two synchronous operation steps in the ignition operation, and these two synchronous operations must be coordinated, otherwise the operation risk is easy to appear, and the specific description is as follows:

when the palm of one hand holds the flame welding gun handle, the thumb and the forefinger synchronously control the acetylene switch knob, the opening size of the knob valve must be proper, the gas in the nozzle is too small and is not easy to ignite successfully, the gas in the nozzle is too large and can cause ignition and deflagration, meanwhile, the flame welding gun must be held stably, otherwise, the direction of the gun head is misaligned, people and objects are burned, or the welding gun cannot be held firmly and falls.

The other hand is operated to enable the igniter to be close to a flame nozzle of the acetylene cutting torch nozzle, the gun head and the acetylene switch knob are operated by one hand, the acetylene switch knob operated by the thumb and the forefinger needs to be accurately matched with the ignition time of the igniter, and otherwise, ignition failure and flame deflagration dangerous events easily occur. Three accurate action two hands are controlled in step, have certain degree of difficulty, need long-term training can master conscientiously. And, once light fails, need close acetylene switch knob, operate again, otherwise can appear near rifle head dispersion a large amount of gas, ignite again and initiate the explosion accident.

In addition to the above-mentioned safety risks, there are two operational risks:

the acetylene cutting nozzle is ignited manually, the handheld igniter and the acetylene nozzle need to keep a proper distance, the gas at the nozzle is not easy to ignite after the distance is too far, a large amount of gas is dispersed, the gas is too close, and the instantly ignited gas can cause hand burning.

In the operation process, due to various factors such as flame tempering, temporary standby, abnormal conditions … … and the like, the flame is temporarily extinguished, and the flame operation is ignited again in a short time, most of operators choose to directly ignite the flame by utilizing the residual fire of the workpiece or use peripheral electric welding for ignition, and the irregular ignition modes of illegal operation save the complexity of single-hand ignition of the lighter, but have inevitable danger due to the unreliability of ignition of open fire and dark fire.
