Abstract

The invention relates to a structure of a gas stove water jacket. A semicircular retaining pipe is welded at the inner side of a jacket outer cylinder body and is communicated with a water vapor discharging pipe, meanwhile, a bottom plate is sealed at the bottom, the bottom plate is provided with a hole with proper size, therefore, when water vapor is discharged out of the water vapor discharging pipe, a certain pressure difference is formed at the inlet and outlet part of the water vapor discharging pipe, water in the water jacket is upwards sprayed from the hole of the bottom plate according to the negative pressure principle, thereby the cooling effect is improved. The invention overcomes the crack defect or bulge at an upper end enclosure part caused by the change of the metallographic structure of the upper end enclosure and the reduction of the mechanical property of the material because high temperature easily influences the surrounding of the water vapor pipe of the prior gas stove water jacket and especially the upper end enclosure part of the water jacket, thereby prolonging the service life of the water jacket.

Description

A kind of structure of gas stove water jacket

Technical field:

The present invention relates to the structure of a kind of water jacket, particularly a kind of gas stove water jacket.

Background technology:

Gas stove water jacket is the visual plant of gas production, its effect is by the water cooling pyritous semi-water gas in the water jacket, thereby the water in the water jacket often is in the condition of high temperature, and produce a large amount of water vapors thus, in order to replenish water coolant, the needs of aspects such as water vapor that discharge produces therefrom and safety, on the upper end of gas stove water jacket outer simplified, be provided with vapour-discharge tube, because vapour-discharge tube is the concentrated path of water vapor drainage water chuck, so be near the vapour-discharge tube, particularly near the chuck upper end enclosure part at top has been assembled a large amount of high-temperature water vapors, near the water vapor of certain pressure has arranged in addition water coolant, institute is so that the chuck upper cover causes the burning state, the metallographic structure of metal changes, reduced the mechanical property of metal, in addition under the effect of certain water vapor pressure, bulge or seminess usually appear near the upper cover of the napex water jacket the water vapor steam discharge pipe, thereby might cause the gas furnace cisco unity malfunction, simultaneously, also reduce the work-ing life of gas furnace.

Summary of the invention:

The invention provides a kind of good cooling results, upper end enclosure part is not subjected to temperatures involved, avoids the upper cover bulge or cracks the coal steam stove water jacket structure of long service life.

Technical solution of the present invention is: the inboard in jacket outside cylinder (3), with (8) seam of semi-circular shelves pipe at the inboard of jacket outside cylinder body (3) and make it to become UNICOM's shape with water vapor vent pipe (7), shut with base plate (9) in the bottom, on base plate (9), have the aperture (Φ) of suitable size, like this, when water vapor vent pipe (7) drainage water steam, import and export the position at it and form certain pressure difference, according to principle of negative pressure, then the water in the water jacket has improved cooling performance by upwards ejection of base plate (9) aperture (Φ).

The invention has the beneficial effects as follows: overcome near the existing gas stove water jacket water vapor vent pipe, particularly the chuck upper end enclosure part is subject to temperatures involved, cause that the upper cover metallographic structure changes, the mechanical property of materials reduces, and the upper cover bulge that therefore causes or crack defective, thereby improve service life of equipment.

Description of drawings:

Below in conjunction with accompanying drawing, the present invention is further described.

Accompanying drawing is a structure principle chart of the present invention;

Shown in the figure: 1, U type upper cover; 2, chuck inner barrel; 3, chuck is outer simplified; 4, U type lower cover; 5, blow-off pipe; 6, water inlet pipe; 7, water vapor vent pipe; 8, retaining pipe; 9, base plate.

Embodiment:

The inboard of simplified outside chuck (3), with the inboard of semi-circular shelves pipe (8) seam simplified chuck outside (3) and make it to become UNICOM's shape with water vapor vent pipe (7), shut with base plate (9) in the bottom, on base plate (9), have the aperture (Φ) of suitable size, like this, when water vapor vent pipe (7) drainage water steam, import and export the position at it and form certain pressure difference, according to principle of negative pressure, then the water in the water jacket has improved cooling performance by upwards ejection of base plate (9) aperture (Φ).Should try one's best near position under the outlet of water vapor vent pipe (7) in the last plane of base plate (9) in design, and base plate (9) aperture (Φ) should or calculate and determine according to experiment.

Claims

1, a kind of structure of gas stove water jacket, it is characterized in that: inboard in jacket outside cylinder (3), with (8) seam of semi-circular shelves pipe at the inboard of jacket outside cylinder body (3) and make it to become UNICOM's shape with water vapor vent pipe (7), simultaneously, shut with base plate (9) in the bottom, have the aperture (Φ) of suitable size on the base plate (9).

2, the structure of a kind of gas stove water jacket according to claim 1 is characterized in that: upper cover; Lower cover is the U type.
