Abstract

A gas pipe comprises a pipe body (1), burners (2) and a connecting plate (3), wherein a seal (4) is formed at one end of the pipe body (1) in a mechanical pressurization mode after the end of the pipe body (1) is heated at high frequency; turned edges (6) with certain heights are formed in the pipe body (1) and at positions, with the burners (2), of the pipe body (1) by using reversely stamped holes; inner taper threads (7) are formed on each turned edge; outer taper threads (8) are formed on a joint of each burner (2) and the pipe body (1); the outside of the other end of each burner (2) is machined to form a hexagonal part (9); the inside of each burner (2) is machined to form an inverted horn mouth; the diameter of the lower part of each burner (2) is large, and the aperture of a gas outlet of each burner (2) is small; and a connecting plate (3) is also welded on the pipe body (1). The gas pipe is simple in structure, low in manufacturing cost and practical.

Description

A kind of fuel tube

Technical field

The present invention relates to a kind of pipe fitting, be specifically related to a kind of fuel tube.

Background technique

Generally use fuel tube in engineering and the daily life, like combustion gas gas pipe or the like, the one of which end should seal, and the other end is connected with source of the gas or other pipeline, and some apertures are arranged on pipe fitting, is used for the install combustion mouth.

Be to adopt long tube sawed-off basically in the production, the end socket sealing is installed in the end, and flame tube and the weldering of burner place are connected with joint, complex structure, cost height.

Summary of the invention

In order to overcome existing fuel tube complex structure, deficiency that cost is high, the utility model provides a kind of fuel tube of simple in structure, low cost of manufacture.

The utility model is realized through following technological scheme:

A kind of fuel tube of simple in structure, low cost of manufacture comprises body, connecting plate and burner.

After one end of body adopts radio frequency heating, seal, do not need to add part in addition and seal, be processed with tapered thread at the other end of body, so that be connected with source of the gas or other pipeline with mechanical pressing mode formation.

Install combustion mouth place on body adopts the recoil hole to form the flange of certain altitude in the inside of body, and on flange, processes inside tapered thread, directly is connected with the outer cone thread of burner lower end, does not need to add in addition joint.

The size of body, shape, the quantity of air outlet, size and distribution are confirmed as required.

The part that on burner, is connected with body is processed with outer cone thread, is processed into hexagon in the other end outside of burner, is convenient to directly burner is screwed in the body.

Horn mouth is processed down in inside at burner, below diameter big, the aperture, place of giving vent to anger is little, makes to discharge gas and form certain pressure.

On body, also be welded with connecting plate.

The beneficial effect of the utility model is: simple in structure, practical, fabricating cost is low.

Specific embodiment

Like Fig. 1-a kind of fuel tube shown in Figure 7, comprise body 1, burner 2 and connecting plate 3, after an end of body 1 adopts radio frequency heating, seal 4 with mechanical pressing mode formation, do not need to add part in addition and seal.

The other end at body 1 is processed with tapered thread 5, so that be connected with source of the gas or other pipeline.

Install combustion mouth 2 places on body 1 adopt the recoil hole to form the flange 6 of certain altitude in the inside of body 1, and on flange, process inside tapered thread 7, directly are connected with the outer cone thread 8 of burner 2 lower ends, do not need to add in addition joint.

The size of body 1, shape, the quantity of air outlet, size and distribution are confirmed as required.

The part that on burner 2, is connected with body 1 is processed with outer cone thread 8, is processed into hexagon 9 in the other end outside of burner 2, be convenient to directly burner 2 is screwed in the body,

Process down horn mouth 10 in the inside of burner 2, below diameter big, the aperture, place of giving vent to anger is little, makes to discharge gas and form certain pressure.

On body 1, also be welded with connecting plate 3.

Claims

1. fuel tube; Comprise body (1), burner (2) and connecting plate (3); It is characterized in that: after an end of body (1) adopts radio frequency heating, seal (4), go up install combustion mouth (2) at body (1) and locate with mechanical pressing mode formation; Adopt the recoil hole to form the flange (6) of certain altitude, and on flange, process inside tapered thread (7) in the inside of body (1).

2. a kind of fuel tube according to claim 1 is characterized in that: go up the part that is connected with body (1) at burner (2) and be processed with outer cone thread (8), be processed into hexagon (9) in the other end outside of burner (2).

3. a kind of fuel tube according to claim 1 is characterized in that: process down horn mouth (10) in the inside of burner (2), below diameter big, give vent to anger the place aperture little.
