Abstract

The utility model provides a burning torch, include: the burning torch casing, the burning torch body of a gun, the rifle head is installed in the overhead center electrode of rifle, burning torch switch, the body of a gun is equipped with the internal thread, the rifle head is equipped with the external screw thread with that end that the body of a gun is connected, the rifle head passes through threaded connection with the body of a gun, it is crooked that the rifle head is the L type, the overhead U type welding rod of installing of rifle, the overhead cover of rifle has the clamp, U type welding rod contacts with center electrode for one section, and the other end passes through clamp and rifle head swing joint. Through setting up the installation internal thread at burning torch rifle head for the dismantlement can be installed to the rifle head, has saved and has traded the rifle spending, through set up installation U type welding rod at center electrode, prevent electrode oxidizing, prolonged the electrode life to extension rifle head live time. U type welding rod can pass through clamp swing joint to can avoid the potential safety hazard through the position adjustment gap size and the position of adjustment U type welding rod, improve the safety guarantee.

Description

A kind of burning torch

Technical field

The utility model relates to mechanical field, and particularly petroleum machinery field, refers more particularly to a kind of burning torch.

Background technology

In drilling process, often need to use burning torch lights a fire.

But at several mouthfuls of wells of dismounting or after using after a period of time, rifle head there will be infringement in various degree to burning torch, electrode also there will be serious oxidation, at this time just needs transducer set new burning torch, price and costliness thereof again. In addition, in prior art, burning torch rifle head adopts straight line design, bad control flare direction and size more, cause certain potential safety hazard, how could both meet the needs of site safety, and can save again a large sum of expense, the new problem that this has just become us to solve.

Utility model content

In order to solve the oxidizable damage of burning torch rifle head central electrode in prior art, and electrode flare direction and the size shortcoming such as wayward, the utility model provides a kind of burning torch, comprise: burning torch housing, the burning torch body of a gun, rifle head, be installed on the central electrode on rifle head, switch of ignition gun; The described body of a gun is provided with internal thread; That end that described rifle head is connected with the body of a gun is provided with external screw thread, and described rifle head and the body of a gun are threaded connection;

Described rifle head is L-type bending;

On described rifle head, U-shaped welding rod is installed;

On the sidewall of described U-shaped welding rod one end, evenly arrange through hole is installed; On the rifle head that through hole is corresponding on the sidewall of described one end, evenly arrange protruding holding section be installed,, described another sidewall of U-shaped welding rod contacts with central electrode.

The number of described through hole and protruding holding section is two or more.

Between spacing between described through hole and protruding holding section, spacing equates.

Described U-shaped welding rod is stainless steel.

Described central electrode is cone; Described cone tip is flare blow-off point.

The utility model has the advantage of:

1, by installation internal thread being set at burning torch rifle head, make the rifle head can installing/dismounting, save and changed rifle spending;

2, by arranging at central electrode, U-shaped welding rod is installed, is prevented anodizing, extended electrode life, thereby extend rifle head service time.

3, U-shaped welding rod can be connected with engaging place of projection by through hole, thereby can adjust gap size and position by the position of adjusting U-shaped welding rod, has avoided potential safety hazard, has improved safety guarantee.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of engaging place of the utility model projection.

Wherein, 1, the body of a gun; 2, switch of ignition gun; 3, rifle head; 4, central electrode; 5, U-shaped welding rod; 6, one end sidewall of U-shaped welding rod; 7, through hole; 8, internal thread; 9, external screw thread; 10, the holding section of projection.

Detailed description of the invention

As shown in Figure 1, a kind of burning torch of the utility model, comprising: burning torch housing, and the burning torch body of a gun 1, rifle head 3, is installed on the central electrode 4 on rifle head 3, switch of ignition gun 2; It is characterized in that: the described body of a gun 1 is provided with internal thread 8; That end that described rifle head 3 is connected with the body of a gun 3 is provided with external screw thread 8, and described rifle head 3 is threaded connection with the body of a gun 1;

Described rifle head 3 is L-type bending;

U-shaped welding rod 5 is installed on described rifle head 3;

On described U-shaped welding rod 5 one end sidewalls 6, evenly arrange through hole 7 is installed; On the sidewall 6 of described one end, on the rifle head of through hole 7 correspondences, evenly arrange protruding holding section 10 is installed, described U-shaped welding rod 5 another sidewalls contact with central electrode 4.

Specifically, rifle head is designed to flare that L-type prevents directly to injection, causes potential safety hazard; On rifle head, install U-shaped welding rod additional, protect central electrode with this, prevent that central electrode is oxidized simultaneously.

In addition, on rifle head, the effect of U-shaped welding rod 5 is, through hole 7 and protruding card and portion 10 can control the distance of U-shaped welding rod 5 and central electrode, test like this and adjust direction and the size of gap, in the time that U-shaped welding rod 5 is adjusted to an optimum position with central electrode, closed clip, fixes it.

As shown in Figure 2, the number of described through hole 7 and protruding holding section 10 is two or more.

In practical operation, the holding section 10 of projection can embed in through hole 7 and be fixed. The number of described through hole 7 and protruding holding section 10 is two or more.

Described through hole 7 and protruding holding section 10 be horizontal arranged in co-axial alignment on one end of U-shaped welding rod 5 sidewall 6 respectively.

Specifically, so the diameter of one end sidewall 6 of U-shaped welding rod 5 can change along with the switching at engaging position, thereby can be flexibly connected U-shaped welding rod 5.

Described U-shaped welding rod 5 is stainless steel.

Selecting stainless steel is a kind of optimal way of the present utility model, and this is because adopt stainless steel can prevent from the oxidation of central electrode being not limited in this in practical operation, can also select other can oxidation resistant metal material.

Described central electrode 4 is cone; Described cone tip is flare blow-off point.

The electrode more electric voltage at small electrode tip is just more concentrated, and the electric field that affect required voltage is just stronger, and required voltage is just lower. So central electrode diameter tip will be polished into taper in the utility model, and adjust gap.
