Abstract
The utility model relates to a constant-pressure liquid-fuel stove which is characterized in that a pressure limiting valve (3) is arranged on the upper part of a fuel tank (1). When the pressure in the fuel tank (1) is lower than the pressure in a pressurizing pipe (7), the valve of the pressure limiting valve (3) is automatically opened, and the pressurizing pipe (7) carries out pressurization for the fuel tank (1). When the pressure in the fuel tank (1) is higher than the pressure in a pressurizing pipe (7), the valve of the pressure limiting valve (3) is automatically closed, and the pressurizing pipe (7) does not carry out pressurization for the fuel tank (1). The utility model is operated in such a circulation way, and the pressure in the fuel tank (1) is correspondingly constant. Compared with the original stoves, the hidden fire danger is eliminated and the combustion is stable.
Description
The utility model relates to a kind of domestic stove, specifically a kind of liquid fuel range of constant pressure.
922128758), self-pressing type liquid fuel burner (the kitchen range) (patent No.: 91212962X) and self-pressing type liquid fuel furnace (the kitchen range) (patent No.: 922123357) of lighting a fire automatically the liquid fuel range of the automatic supply fuel of now the having authorized (patent No.:, because stove (kitchen range) tool does not have pressure limiting device, the pressure in the fuel tank changes with many factors vary such as burner hearth firepower size, burning time, environment temperatures.This stove (kitchen range) tool is in when work, firepower shakiness, and after the fuel tank internal pressure rises to certain value, will have liquid to release in the burner hearth, and light contaminated environment then, heavy then cause fire.
The purpose of this utility model provide a kind of keep the fuel tank internal pressure at rated value with interior liquid fuel range.
The utility model is realized by the following technical solutions: on the top of fuel tank (1) pressure limiting valve (3) is housed, the one end is communicated with fuel tank (1) top by air inlet pipe (2), perhaps directly be communicated with fuel tank (1), the other end is communicated with pressure inlet (7).When fuel tank (1) internal pressure during greater than pressure inlet (7) internal pressure, the pressure limiting valve valve is closed automatically, and pressure inlet (7) is not to fuel tank (1) supercharging; When fuel tank (1) internal pressure during less than pressure inlet (7) internal pressure, the pressure limiting valve valve is opened automatically, and pressure inlet (7) is to fuel tank (1) supercharging, and so circulation makes that the pressure in the fuel tank (1) is constant relatively.
Owing to adopted above-mentioned technical solution, make that the pressure in the fuel tank (1) is constant relatively, thereby stopped disaster hidden-trouble, and flameholding.
Description of drawings:
Fig. 1 is the utility model embodiment 1 main generalized section of looking
Fig. 2 is the utility model embodiment 2 main generalized sections of looking
Embodiment 1:
As shown in Figure 1, the bottom of fuel tank (1) is provided with woven hose (11) and extends to vaporizer (6) bottom, be branched into two-way through threeway, the voltage-stabiliser tube (8) of leading up to enters vaporizer (6), and another road is communicated with fuel tank (1) by pressure inlet (7), pressure limiting valve (3); Pressure limiting valve (3) is contained in the top of fuel tank (1), the one end is communicated with fuel tank (1) by air inlet pipe (2), the other end is communicated with pressure inlet (7), when burning, the liquid fuel vaporization of being heated in vaporizer (6) is transported to by appendix (9) on the one hand and enters burner hearth (5) in the induction tunnel (10) and burn; Pass through transfusion voltage-stabiliser tube (8), pressure inlet (7) on the one hand to fuel tank (1) supercharging.Along with factor affecting such as burning time, burner hearth firepower, temperature, fuel tank (1) internal pressure constantly raises, and when greater than pressure inlet (7) internal pressure, pressure limiting valve (3) cuts out automatically, and pressure inlet (7) is not to fuel tank (1) supercharging; When pressure inlet (7) internal pressure during greater than fuel tank (1) internal pressure, pressure limiting valve (3) is opened automatically, and pressure inlet (7) is to fuel tank (1) supercharging, and so circulation makes the fuel tank internal pressure constant relatively, thereby stopped disaster hidden-trouble, and flameholding.
Embodiment 2: pressure limiting valve (3) one ends directly are communicated with fuel tank (1), and the other end is communicated with pressure inlet (7), and all the other are with embodiment 1.
Claims (3)
1, a kind of liquid fuel range of constant pressure, it comprises fuel tank (1), burner hearth (5), vaporizer (6), pressure inlet (7), appendix (9), induction tunnel (10), woven hose (11) and pre-heating fuel dish (12) etc., and feature of the present utility model is on the top of fuel tank (1) pressure limiting valve (3) to be housed.
2, the liquid fuel range of a kind of constant pressure according to claim 1 is characterized in that pressure limiting valve (3) one ends are communicated with fuel tank (1), and the other end is communicated with pressure inlet (7).
3, the liquid fuel range of a kind of constant pressure according to claim 1 is characterized in that pressure limiting valve (3) one ends are communicated with fuel tank (1) by air inlet pipe (2), and the other end is communicated with pressure inlet (7).
