Description

Diesel oil blowtorch lamp holder

The utility model relates to a kind of fuel oil heater.

At present, the use of Oil-burning blow torch is quite general, all will relate in industries such as buildings waterproof, erecting cables, particularly at northern area, also often will use Oil-burning blow torch when starting up the car and come preheating.Because it is with ejection burning again after the oil plant vaporization, so its temperature height, the thermal efficiency are also high.But existing blowtorch is to use gasoline to act as a fuel basically, because lower, the easy vaporization of the burning-point of gasoline, yet to use diesel oil to act as a fuel, must improve existing Blowtorch structure so.

The purpose of this utility model is: a kind of diesel oil blowtorch lamp holder is provided, and it improves existing blowtorch holder structure, can use diesel oil to act as a fuel, and reliable and stable.

The technical solution of the utility model is: a kind of diesel oil blowtorch lamp holder comprises interconnective oily steam pipe and the cylinder and the pipe of starting to exchange fire in the cover circle head, outer cover of outer cover, outer cover front end; Described oily steam pipe is made up of helix tube, last straight tube, lower straighttube, last straight tube links to each other with the cold oil fuel feed hole with the oily vapour venthole at cylinder two ends respectively with lower straighttube, the end of oil vapour venthole is that the stage casing of cylinder is provided with nozzle, described lower straighttube is positioned at the outside of outer cover, be provided with the preheating cup below the lower straighttube, the junction of lower straighttube and cold oil fuel feed hole is provided with control valve, and the described pipe of starting to exchange fire is positioned at the middle part of the line of nozzle and helix tube; Described control valve is made up of cold oil fuel feed hole, spool, valve seat, seal by conical contact face between spool and the cold oil fuel feed hole, by being threaded, and be provided with the sealed nut compressing of graphite gasket between spool and the valve seat, the rear end of spool is provided with rotary handle; Described cover circle head is thin and long.

The utility model has the advantages that:

1. the utility model uses diesel oil to act as a fuel, the burning-point height of the gasoline that compares, be difficult for vaporization, so control valve will be arranged on the junction of lower straighttube and cold oil fuel feed hole, so that oil and vapour behind the closed control valve in the oily steam pipe still can spray after-flame, otherwise, will cause the obstruction and the leakage of oily steam pipe easily.

2. because the fuel that the utility model uses is diesel oil, so lower straighttube is arranged on the outside of outer cover, directly be exactly the preheating cup below, pre-like this warm up more favourable and quick.

3. just because of the utility model uses is that diesel oil acts as a fuel, so oily steam pipe is made helix tube in the front of the pipe of starting to exchange fire, the heat of the pipe ejection of starting to exchange fire quickens the vaporization of the interior cold oil of oily steam pipe.

The utility model will be further described below in conjunction with drawings and Examples:

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

Wherein: 1. outer cover; 2. cover encloses head; 3. oily steam pipe; 4. cylinder; 5. the pipe of starting to exchange fire; 6. helix tube; 7. go up straight tube; 8. lower straighttube; 9. oily vapour venthole; 10. cold oil fuel feed hole; 11. nozzle; 12. preheating cup; 13. control valve; 14. spool; 15. valve seat; 16. graphite gasket; 17 sealing nuts; 18. rotary handle.

Embodiment: as shown in Figure 1, a kind of diesel oil blowtorch lamp holder comprises interconnective oily steam pipe 3 and cylinder 4 and the pipe 5 of starting to exchange fire in the cover circle 2, outer cover 1 of outer cover 1, outer cover 1 front end; Described oily steam pipe 3 is made up of helix tube 6, last straight tube 7, lower straighttube 8, last straight tube 7 links to each other with cold oil fuel feed hole 10 with the oily vapour venthole 9 at cylinder 4 two ends respectively with lower straighttube 8, the end of oil vapour venthole 9 is that the stage casing of cylinder 4 is provided with nozzle 11, described lower straighttube 8 is positioned at the outside of outer cover 1, be provided with preheating cup 12 below the lower straighttube 8, lower straighttube 8 is provided with control valve 13 with the junction of cold oil fuel feed hole 10, and the described pipe 5 of starting to exchange fire is positioned at the middle part of the line of nozzle 11 and helix tube 6; Described control valve 13 is made up of cold oil fuel feed hole 10, spool 14, valve seat 15, seal by conical contact face between spool 14 and the cold oil fuel feed hole 10, between spool 14 and the valve seat 15 by being threaded, and be provided with graphite gasket 16 sealed nuts 17 and compress, the rear end of spool 14 is provided with rotary handle 18; Described cover circle 2 a thin and length.The utility model uses diesel oil to act as a fuel, the burning-point height of the gasoline that compares, be difficult for vaporization, so control valve 13 will be arranged on the junction of lower straighttube 8 and cold oil fuel feed hole 10, so that oil and vapour in the oily steam pipe 3 in closed control valve 13 backs still can spray after-flame, otherwise, will cause the obstruction and the leakage of oily steam pipe 3 easily; Because the fuel that the utility model uses is diesel oil, so lower straighttube 8 is arranged on the outside of outer cover 1, directly be exactly preheating cup 12 below, pre-like this warm up more favourable and quick; Just because of the utility model use is that diesel oil acts as a fuel, so oily steam pipe 3 is made helix tube 6 in the front of the pipe 5 of starting to exchange fire, the heats of pipe 5 ejections of starting to exchange fire quicken the vaporization of cold oil in the oily steam pipe 3.
