Description
Technical field
The present invention relates to a kind of security protection system of gas combustion apparatus.Topple over flame-out guarantor more particularly to a kind of parallel combustion gas
Protect device.
Background technology
Existing gas extinguishing fire protector main operational principle is all by solenoid-operated switch, closed type dumping switch, is lacked
Oxygen protector (ODS) is composed in series.Artificial positive opening electromagnetic valve switch, and during to anoxic protector ODS heating, ODS
A potential can be produced and carry out the electromagnetic valve coil that adhesive is connected on loop, when caused loop current is more than the guarantor of solenoid electric valve
When holding electric current, solenoid electric valve adhesive self-insurance, gas circuit is set to keep the state opened, system keeps normal working condition, now such as
Fruit system tilt falls down, and the dumping switch contact connected in loop disconnects, and cut-off loop electric current, magnetic valve return is source of the gas pass
Close, reach the flame-out purpose to ensure safety, horizontal according to current technology, domestic monopole E types thermocouple output is maximum, in Chang Minghuo
20MV or so can be reached during 650 degrees Celsius of flame, system internal resistance is constant in potential V according to Ohm's law I=V/R in 80-150M Ω
In the case of, internal resistance is bigger, and the electric current in loop is smaller, when loop current is less than the holding electric current of magnetic valve, Electromagnetic Control
Valve cannot cause gas circuit not open by adhesive.So existing pouring protecting device, just occurs such situation, make
After a period of time, stove just occurs that sparking can fire to loose one's grip and just gone out, it is impossible to the phenomenon of self-insurance.There is the reason for this phenomenon just
To topple over internal resistance in protection system in use, internal resistance increase gradually, when system internal resistance increase to a certain extent,
Toppling over the electric current in protective loop will reduce, when reduce to a certain extent, less than solenoid electric valve keep electric current when, electromagnetism control
Valve processed cannot adhesive, gas circuit of not opening, so without fuel gas supply, beat naturally missing of ignition.The reason for system internal resistance increases has：
1, connect impaling member contact internal resistance oxidation and become big.2, internal resistance oxidation in normally closed type anti-tilt switch contact becomes big.3, stove is in circuit system
System pollution, it is dirty.
By taking fuel gas heating apparatus as an example：Many warmers can be fired using sparking is occurred as soon as after one or two years, loosed one's grip and just gone out, it is impossible to
The phenomenon of self-insurance, main cause are system internal resistance increases, and loop current is less than solenoid electric valve and keeps electric current, makes to topple over protector
In solenoid electric valve be unable to adhesive, influence gas circuit it is unimpeded the reason for.
The content of the invention
It is an object of the invention to provide a kind of parallel combustion gas to topple over break off preventor, solve in circuit internal resistance increase and
The problem of causing combustion gas gas circuit not opened.
In order to achieve the above object, the present invention has following technical scheme：
Break off preventor, including solenoid electric valve, dumping switch, anoxic protection are toppled in a kind of parallel combustion gas of the present invention
Device, the dumping switch are normally opened contact formula dumping switch, and the normally opened contact formula dumping switch and battery are first cascaded,
Then the both ends of solenoid electric valve are connected in parallel on again, and solenoid electric valve is in parallel with anoxic protector.
Wherein, the battery is a 1.5V dry cell.
Wherein, the parallel combustion gas topples over the circuit connection point of break off preventor using soldering connection.
Due to taking above technical scheme, the advantage of the invention is that：
1 present invention is exactly to have changed the closed type dumping switch of prior art into normally opened contact formula dumping switch, and is increased
Add 1.5V dry cell, so solve in circuit, and the problem of normally-closed contact formula dumping switch internal resistance increase.
2 in order to ensure that the present invention's is accurate sensitive, and the tie point of circuit of the invention is connected using soldering, is thus solved
Prior art of having determined makes the disadvantage of internal resistance increase using the oxidation of impaling member tie point.

Embodiment
Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
Referring to Fig. 1-Fig. 2, break off preventor is toppled in a kind of parallel combustion gas of the present invention, by solenoid electric valve, dumping switch,
Anoxic protector forms, and the dumping switch is normally opened contact formula dumping switch, the normally opened contact formula dumping switch and one
1.5V batteries are first cascaded, and are then connected in parallel on the both ends of solenoid electric valve again, solenoid electric valve and anoxic protector are simultaneously
Connection.
The circuit connection point that break off preventor is toppled in the parallel combustion gas is connected using soldering.
Under normal circumstances, the shift knob of gas utensil is pressed, is turned on Chang Minghuo, Chang Minghuo burns ODS, is heated to ODS,
Will produce a potential in ODS circuits, this potential will the solenoid electric valve of adhesive series connection in circuit coil, so
Solenoid electric valve adhesive, gas circuit conducting, flame combustion, gas utensil normal work.When gas utensil is tilted or fallen down, normally opened contact
Formula dumping switch is closed, and circuit is connected, and the 1.5V dry cells for being connected in parallel on solenoid electric valve both ends can be short in Electromagnetic Control valve coil
Add a reverse potential in time, drop to solenoid electric valve electric current and keep below electric current, and solenoid electric valve is departed from adhesive,
So as to close gas circuit, reach the purpose of blowout protection.
In the specific operation, the mounting means and prior art of break off preventor are toppled in parallel combustion gas of the invention
The installation for toppling over protector is slightly different：ODS solenoid electric valves are arranged on boxboard first, their shell end common ground
（Shell）, they are actually to be installed in parallel, and in the case of pipeline UNICOM, can put to catch fire and are operated, then with a section
Remaining both threads are coupled with the both ends of Electromagnetic Control valve coil i.e. after 1.5 volts of dry cells and dumping switch open in usual series connection
Can.Stirring movable contact makes it be contacted with stationary contact, and solenoid electric valve, which is closed, to stop working, and if do not stopped working, is by battery polar reversal connection
Can.
Obviously, examples detailed above of the invention is only intended to clearly illustrate example of the present invention, and is not to this
The restriction of the embodiment of invention.For those of ordinary skill in the field, on the basis of the above description can be with
Make other changes in different forms.Here all embodiments can not be exhaustive.It is every to belong to the present invention
The obvious changes or variations extended out of technical scheme still in protection scope of the present invention row.
