Description

The energy-saving safe cutting torch

Technical field

The utility model relates to a kind of cutting torch, belongs to the cutting torch technical field.

Background technology

Existing cutting torch (being also referred to as burning torch) exists four technological deficiencies:

1, igniting is dangerous, is easy to burn hand, all will take lighter to light with hand when using at every turn, and is not rapid slightly when igniting because of the pressure of oxygen self, the lighter's Burning Pain, weight person's burn.

2, not energy-conservation, the oxygen-acetylene waste is serious.Use at every turn after lighting and to carry out combustion ratio for a long time, wait for after combustion ratio is adjusted and to cut object.Sometimes it is many to cut the time gas long, that expend that used time of object and gas uses not as good as allotment burning ratio, does not reach the requirement of instantaneous ignition cutting.

3. safe handling property is poor, and oxygen-acetylene respectively has only a switch valve, in use if a little leakage of valve is arranged or easy breaking out of fire or accident when revealing.And the user of service can only run to close the main valve of gas cylinder or gas bag; This gas therebetween leaks abnormally dangerous, and fire disaster or human casualty accident take place easily.The defective that each place use proof cutting torch for many years self exists when making is exactly the potential safety hazard of maximum fire incidents.

The personnel that 4, can not allocate the gas combustion ratio can not use.

Summary of the invention

In order to overcome the weak point of above-mentioned prior art, the utility model provides a kind of energy-saving safe cutting torch, can reach the requirement of energy-conservation, automatic igniting, safety in production and instantaneous ignition moment cutting in the use.

The utility model is realized through following technical scheme: a kind of energy-saving safe cutting torch; It comprises cutting torch body, cutting torch, gas preparing valve and cutting torch handle; There are the oxygen supply passage and the acetylene service duct of mutual isolation to communicate with described gas preparing valve respectively in the described cutting torch handle; On the described cutting torch handle energy-saving safe valve is arranged; The spool of energy-saving safe valve is to be manufactured with oxygen channel that when open mode, can be communicated with oxygen supply passage and gas deployment valve and the acetylene passage that when open mode, can be communicated with acetylene service duct and gas deployment valve on the cylinder spool simultaneously with the cylinder spool of oxygen supply passage and the blocking-up of acetylene service duct; The circumferential position of oxygen channel and acetylene passage differs 180 degree, described cylinder spool axially on be extended with swing handle.

Spark lever is arranged at the bottom of described cutting torch body, on the described cutting torch handle ignition switch is arranged.

Described oxygen channel and acetylene passage pass from the valve inner of described energy-saving safe valve.

Described oxygen channel and acetylene passage are the grooves of on the valve outer wall of described energy-saving safe valve, making.

The beneficial effect of the utility model is: the cutting torch that is using is temporary transient time spent not in the work-yard, as long as the energy-conservation valve of closed safe.When reusing, only need open the requirement that the energy-saving safe valve just can reach instantaneous ignition, moment cutting, raise the efficiency, and need be as prior art long-time allotment two burning of gas ratios, the saving energy.

If when the cutting technique personnel were in short supply, available other staff replaced work.As long as after the allotment well in advance of two burning of gas ratios, with the control of energy-saving safe valve, any staff can cut.

The energy-saving safe valve can realize that oxygen, acetylene two pipelines are with opening, closing together and not connected function.Guaranteed that two gases definitely can not get into its chamber combustion explosion etc. takes place under unequal pressure, safety, reliable.

The specific embodiment

Like Fig. 1, Fig. 2, a kind of energy-saving safe cutting torch shown in Figure 3; It comprises cutting torch body 7, cutting torch 8, gas preparing valve 6 and cutting torch handle 1; There is the oxygen supply passage 2 of mutual isolation to communicate with described gas preparing valve 6 respectively in the described cutting torch handle 1 with acetylene service duct 4; On the described cutting torch handle 1 energy-saving safe valve 5 is arranged; The spool of energy-saving safe valve 5 is to be manufactured with the oxygen channel 5-2 that when open mode, can be communicated with oxygen supply passage 2 and gas deployment valve 6 on the cylinder spool and when open mode, can be communicated with acetylene service duct 4 and the acetylene passage 5-3 of gas deployment valve 6 simultaneously with the cylinder spool of oxygen supply passage 2 with 4 blocking-up of acetylene service duct; The circumferential position of oxygen channel 5-2 and acetylene passage 5-3 differs 180 degree, described cylinder spool axially on be extended with swing handle 5-1.As shown in Figure 2, during open mode, oxygen channel 5-2 connects oxygen supply passage 2 and gas deployment valve 6, and acetylene passage 5-3 connects acetylene service duct 4 and gas deployment valve 6 simultaneously; As shown in Figure 3, after the cylinder spool revolved and turn 90 degrees, when being in closed condition, the cylinder spool was simultaneously with oxygen supply passage 2 and 4 blocking-up of acetylene service duct.

Spark lever 9 is arranged at the bottom of described cutting torch body 7, on the described cutting torch handle 1 ignition switch 3 is arranged.

As shown in Figure 4, described oxygen channel 5-2 and acetylene passage 5-3 pass from the valve inner of described energy-saving safe valve 5.

As shown in Figure 5, described oxygen channel 5-2 and acetylene passage 5-3 are the grooves of on the valve outer wall of described energy-saving safe valve 5, making.

Method for using: the right hand is held the cutting torch handle, opens the energy-saving safe valve with left hand, after thumb promotes ignition switch 3 sparkings, slowly opens oxygen valve with left hand again, and after lighting, hand thumb is unclamped ignition switch and resetted, and igniter stops sparking.Open the acetylene valve with left hand, allocate the gas combustion ratio simultaneously, but get final product operate as normal when treating cutting part.

In the work-yard if temporarily when stopping to cut, as long as the energy-conservation valve of closed safe.When needs again during cutting part, promote the ignition switch sparking after, open the energy-saving safe valve with left hand, can reach the requirement of instantaneous ignition, moment cutting part, not only energy-conservation but also convenient and swift.
