Pressurizing tank 4 is set to the top of heating feeding tank 3, and the water tank 12 surrounded by iron sheet is equipped in the bottom of pressurizing tank 4, water tank 12
The height of 1/2 pressurizing tank 4 of height <, in the present embodiment, the height of the iron sheet of water tank 12 are 5cm.The top of water tank 12 is equipped with
Overflow hole is equipped with venthole 13 between pressurizing tank 4 and heating feeding tank 3, which is connected to venthole 13.
Low pressure steam boiler described in the utility model, workflow are as follows:
The course of work is: by burning in boiler, after being watered by filler pipe, electronic float is housed inside filler pipe, it is electronic
Control switch is connect in the circuit of float, control switch and water pump connect, and the other end leads to power supply.The effect of electronic float is: when
Steam in radiator sinks, and when distilled water flows to recovery tank by return pipe, the water level of recovery tank can be increased slowly, to centainly
Float will sense when position, send signal to control switch, switch just automatically connects circulation pumping source, so that water pump
Work feeds the water into preheating cabinet preheating, and when water level decreasing is to certain position, switch can be automatically closed, and water pump is made to stop working.
It is redirected back into recovery tank in order to control steam in preheating cabinet and water, so lead to the pipeline of preheating cabinet in circulating pump
In be mounted with a preheating cabinet one-way cock, keep it positive logical, it is reversed closed, at this moment heat confession of the water due to steam of feeding tank
It can slowly reduce out, the supply of preheated water slowly is heated feeding tank by preheating cabinet, so that steam normal supply, ensure that warm
The normal heat of gas piece is free of discontinuities.
Water level in preheating cabinet and heating feeding tank is balance, in order to make the water level balance in two casees, so in
Between the lower partition away from having got through the aperture of 8 millimeters of diameter at the 2cm of bottom as water channel, top open one with supply water
The identical hole of channel sized is as air pressure flat hole.In addition, welding one square iron pipe, formed air pressure relief hole, nozzle to
On leave 8cm it made only to cross cannot restrain one's anger water.
Pressurizing tank is arranged at the top of heater box and is communicated by venthole connection, and venthole is four.Welding four each
The iron sheet of 5cm long forms the water tank of a 5cm high so that the water level in pressurizing tank is no more than 5cm, it is extra can be automatically from logical
Stomata flows into heater box.It is 10cm that the purpose being arranged in this way, which is because of pressurizing tank difference height, and air supply pipe is also heating upper box part,
The excessively high steam that can generate of water level is obscured, and steam flow rate is influenced, so being set to 5cm is optimum efficiency, heats the steam in feeding tank
It is combined into one the steam of steam and pressurizing tank into pressurizing tank, it is fast that this creates the terminal steam flow rates, and the big effect of heat exists
Enter radiator from air supply pipe outflow.In addition, being mounted on air supply pipe respectively to make user convenient for grasping pressure and temperature
Pressure gauge and thermometer.
Easy to maintenance in order to make, the especially bursting problems such as radiator blocking are controlled, and are filled on air supply pipe
Air supply pipe check valve, which is in normally opened, and the following and exhaust pipe in air supply pipe check valve is connected to, and in
Between there are also installed valves as safety valve, safety valve often closes.In maintenance and failure, safety valve is opened and by air supply pipe
Upper valve is closed so that steam does not enter radiator and is discharged from exhaust pipe, ensure that secure side maintenance.After maintenance
Two valves are returned into original position, continue heating and do not extinguish the fire in boiler, there are also installed a 0.1- on exhaust pipe top
The one-way cock of 0.15 pressure, the pressure at expulsion in maintenance is greater than 0.1-0.15 so exhaust is smooth.
The effect of the check valve on exhaust pipe top is when long-time increases pressure after firepower makes steam consumption in radiator
Power be greater than 0.15 when, check valve can be opened and be discharged to outside room because exhaust pipe be through to outside, when firepower is small, radiator
When interior steam pressure is less than 0.15, not valve opening door is pushed up, is just stored in heating in radiator, the dual work for playing safety and keeping the temperature
With.
The nozzle of filler pipe is that a pipeline is shared with exhaust pipe, leads to recovery tank, therefore in the intermediate installation of filler pipe
Opening when a valve adds water, closing when adding water, adding the process of water is that water is added from filler, enters return water by pipeline
Case, so that the water level of recovery tank rises, electronic float induction forms cyclic process said before, feeds the water into preheating cabinet, water
Position pipe is mounted on preheating cabinet side, until being added to always away from water level pipe top 2cm or so, when water level is consumed to away from water level pipe top
8cm or so is greater than one week or so time, can supplement until adding water to be added to away from water level pipe top 2cm.
In order to keep the waterproof when flushing type maintains convenient, therefore on water level pipe lower connector and at the threeway of water circulating pump lower part
Respectively there is a waterproof screw, be also plug, it is unscrewed until water flow is complete, is then repeated several times if it is rinsing.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
