CN2142540Y - Balanced steam drum for light type gas fired boiler - Google Patents

Abstract

The utility model relates to a balanced steam drum for a gas fired boiler, which is characterized in that a balanced steam drum is arranged beside the gas storage pipe of the light type gas fired boiler, causing that the liquid petroleum gas in the gas storage pipe can firstly pass the balanced steam drum for being sufficiently liquefied and then reach a fire divider for firing through an adjusting valve. The utility model has the advantages of uniform gas supply, sufficient combustion, no yellow flame, stable flame, etc. and can not only save energy source but also reduce air pollution.

Description

Balanced steam drum for light type gas fired boiler

The utility model relates to a kind of balance tympanites device of gas furnace, is particularly useful in the stove or furnace bottom is equipped with the legerity type gas furnace of cylinder.

Have in the existing legerity type gas furnace and a kind ofly place cylinder in the stove or the portable gas stove of furnace bottom.This stove is not owing to there is a pressure-reducing valve, employing be the high-pressure burner structure, therefore, when the cylinder topping up liquefied oil gas in the stove was too much, liquid will directly be sprayed onto on the burner from nozzle, can occur strong yellow flame during burning, causes fuel combustion insufficient.Both cause certain waste, brought certain air pollution again.

The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provides a kind of interior liquefied petroleum gas combustion of stove that can make to get the balance tympanites device of legerity type gas furnace more fully.

The purpose of this utility model is achieved in that sets up balance tympanites device between the cylinder of legerity type gas furnace and control valve.When liquefied petroleum gas by cylinder after pipeline (8) is sent into the balance valve, the spool (4) in the valve moves up under the effect of air pressure, makes combustion gas enter enraged inner chamber behind crevice throttle thereby open valve.At this moment, air pressure has reduced and has formed pressure reduction, and when the screen resilience sum of pressure in the tympanites and spring equaled combustion gas to the gross pressure of spool, spool just was in poised state, make valve keep certain aperture, thus reach supply gas evenly, combustion flame is stable and effect of sufficient.

Below in conjunction with drawings and Examples the utility model is further elaborated.

The name of each several part is called in the accompanying drawing: snorkel spiral shell seat (1); Balance tympanites (2); O RunddichtringO (3); Movable spool (4); Valve base (5); Clamp nut (6); Rectangular seal (7); Go into gas copper tube (8); Lead gasket (9); Helical spring (10); Snorkel (11); Balance valve (12).

Get steel material and make an airtight container as balance tympanites (2), the volume of tympanites (2) is decided on the size of stove and accessory and the cylinder that is equipped with, gets equal diameter usually.Open a hole at the top of balance tympanites, fix a snorkel (11) with snorkel spiral shell seat (1), the liquefied petroleum gas that has been gasified totally in the tympanites outputs to control valve and distributor thus.Connect a balance valve (12) by screw at balance tympanites (2) on perpendicular to an end face of axis.Balance valve (12) is connected with placing stove cylinder interior or furnace bottom.Balance valve (12) by O RunddichtringO (3), movable spool (4), valve base (5), clamp nut (6), rectangular seal (7), go into gas copper tube (8), lead gasket (9), helical spring (10) and constituted.At valve base (5) built-in one movable spool (4), place a helical spring (10) on it, the front end of movable spool (4) is opened an annular groove and is put an O RunddichtringO (3), valve base (5) contacts with tympanites (2) and disposes a lead gasket (9), goes into the other square RunddichtringO (7) of establishing of gas copper tube (8).Rely on springback power to make movable spool (4) compress sealing ring (3), reach the effect of closing with the by-pass valve control open degree.Valve base (5) other end also has screw thread, will go into gas copper tube (8) and rectangular seal (7) compresses by clamp nut (6), does not have gas leak phenomenon when guaranteeing gas.

The utility model is by making liquefied petroleum gas stored in the legerity type gas furnace fully transport to control valve and distributor after the gasification through the balance tympanites again, has the advantage such as supply gas evenly, sufficient combustion, the yellow flame of nothing, flare are stable, both but energy savings can reduce air pollution again.

Claims (2)

1, a kind of balance of legerity type gas furnace tympanites device, form by balance tympanites (2), balance valve (12) and snorkel (11) etc., it is characterized in that tympanites (2) is an airtight container, connect a balance valve (12) by screwed hole on perpendicular to an end face of axis at it.

2, balance tympanites device according to the described legerity type gas furnace of claim 1, it is characterized in that the balance valve is by O RunddichtringO (3), movable spool (4), valve base (5), clamp nut (6), rectangular seal (7), go into gas copper tube (8), lead gasket (9), helical spring (10) constitutes, movable spool (4) is positioned at base, place a helical spring (10) on the spool, the front end of spool is opened an annular groove and is put an O RunddichtringO (3), valve base (5) contacts with tympanites (2) and disposes a lead gasket (9), goes into the other rectangular seal (7) of establishing of gas copper tube (8).
