Abstract

An adjustable light hydrocarbon gas water heater is composed of water inlet and outlet pipelines, gas collecting tube with a row of air nozzles, a group of combustion chambers with air inlet and air outlet opposite to the air nozzles of gas collecting tube, and a heat exchanger communicated with combustion chambers. It has the advantage of conveniently adjusting the amount of air entering to participate in the combustion reaction.

Description

Adjustable light-hydrocarbon gas water heater

The utility model relates to gas heater, particularly uses the gas heater of light-hydrocarbon fuel.

Except that natural gas, oil liquefied gas, light hydrocarbon liquid fuel (the following hydrocarbon mixture of C5) also is a kind of domestic fuel preferably.It has the calorific value height, uses price low, and accumulating is convenient, need not lay the line (for natural gas), and normal pressure is burning advantages such as (for oil liquefied gas) down.Its shortcoming is because it is the multicomponent hydrocarbon mixture, and light component mainly consumes at the burning initial stage, and heavy ends then mainly consumed in the burning later stage, thereby the combustion heat instability of sending in the combustion process.The existing gas heater that uses light hydrocarbon liquid fuel, the air inlet of the row's puff prot of one on its discharge and one group of combustion chamber is one by one over against setting, and maintain the 2-3cm spacing, entering air consumption that the combustion chamber participates in combustion reaction can not change in the combustion process of whole light-hydrocarbon fuel and can not regulate, on the one hand, the calorific value of fuel is changing, and variation big (natural gas, liquefied gas relatively), on the other hand, the air consumption that participates in burning but remains unchanged, and this obviously is unreasonable and uneconomic.

Task of the present utility model is to overcome the deficiencies in the prior art part and a kind of adjustable light-hydrocarbon gas water heater is provided, and it can control the air consumption that enters the combustion chamber.

Task of the present utility model realizes by following design: a kind of adjustable light-hydrocarbon gas water heater, comprise into, outlet conduit, be communicated with air inlet pipe, distribute on it and be provided with the discharge of row's puff prot, its air inlet and discharge puff prot are one by one over against setting, and the one group of combustion chamber that keeps a determining deviation, and the heat exchanger that is communicated with the combustion chamber, it is characterized in that, be connected with an interior mouth that has a through hole on the puff prot of described discharge, the interior mouth other end is connected with the outer mouth that has through hole, spiral is connected with a nut on the outer mouth other end, and outer mouth other end gas outlet is directly stretched in the air inlet of combustion chamber behind this nut; The fresh air inlet circle of position on the Wai Zui side is with the adjusting ring cowling that has fresh air inlet equally.

By above design as seen, connect a Nei Zui and Wai Zui from the puff prot of discharge, directly the gas outlet is stretched in the air inlet of combustion chamber, make combustion gas directly enter the combustion chamber from discharge, the air that participates in combustion reaction then enters the combustion chamber in the fresh air inlet place on the Wai Zui side, and the air consumption is then by regulating ring cowling control and regulating.Only need the rotation snare position of the adjusting ring cowling on the mouth outside, adjust the topped degree of its fresh air inlet and outer mouth fresh air inlet, can conveniently reach the purpose of adjusting intake.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the utility model schematic perspective view;

Fig. 2 Fig. 3 is respectively the front view (section) and the left view of interior mouth shown in Figure 1;

Fig. 4 is the profile of outer mouth shown in Figure 1;

Fig. 5 Fig. 6 is respectively the front view and the upward view of adjusting ring cowling shown in Figure 1.

Fig. 1 illustrates (referring to Fig. 2-6), the discharge 7 general square pipes that adopt, and it is communicated with air inlet pipe.Discharge is provided with a row puff prot 7a (only drawing among Fig. 1 one), and one group of air inlet 6 that burn to burn chamber 8 and discharge puff prot be one by one over against setting, and keeps a determining deviation (not drawing among Fig. 1 such as water-in and water-out pipeline and heat exchanger).Interior mouth 1 has through hole, and the aperture is φ 3mm, and interior mouth is connected with the discharge spiral, and the interior mouth other end is connected with outer mouth 2 spirals, and the two joint face is provided with sealing ring (annular groove 1a is that sealing ring embeds the position among Fig. 2).Spiral is connected with a nut 5 on the outer mouth other end, has 4 fresh air inlet 2a on the side of outer mouth, regulates on the ring cowling 3 and has 4 fresh air inlet 3a equally, and the adjustable ring decorative cover overlaps the fresh air inlet position of mouth outside.Outer mouth other end gas outlet (is promptly passed) in the air inlet that directly stretches into the combustion chamber behind nut 5.The through-hole diameter of outer mouth is 3mm at the minimum place of its fresh air inlet leading portion (for airintake direction), and the fresh air inlet back segment is 6mm.The outer mouth position of regulating between ring cowling and the nut is provided with a spring 4.Adjustable ring covers and is provided with handle 3b.During assembling, rotation nut 5 makes on its air inlet that is sealed on combustion chamber 86.Spring 4 makes to be regulated the ring cowling location and is convenient to rotation.During use, rotate to regulate ring cowling, can conveniently regulate the combustion air consumption (in the practical set, just in time be handstand setting shown in Figure 1, promptly combustion chamber 8 up, discharge 7 below).
