Abstract
The utility model relates to a parallel type gas-pouring flameout protector comprising an electromagnetic control valve, a pouring switch and an oxygen deficit protection device. The pouring switch is a normally-opened contact type pouring switch which is serially connected with a battery first and then is parallelly connected at two ends of the electromagnetic control valve, and the electromagnetic control valve is connected with the oxygen deficit protection device in parallel. The parallel type gas-pouring flameout protector solves the problem that a gas way cannot be opened due to the fact that internal resistance in a circuit is increased.
Description
Technical field
The present invention relates to a kind of security protection system of gas combustion apparatus.Be specifically related to a kind of parallel combustion gas and topple over break off preventor.
Background technology
Existing gas extinguishing fire protector groundwork principle all is by solenoid-operated switch, the closed type dumping switch, and anoxic protector (ODS) is composed in series.The people is the positive opening electromagnetic valve switch, and when giving anoxic protector ODS heating, ODS can produce an electromotive force and come adhesive to be connected on the electromagnetic valve coil in loop, when the loop current that produces during greater than the maintenance electric current of solenoid electric valve, solenoid electric valve adhesive self-insurance, make gas circuit keep the state of opening, system keeps normal duty, if system tilted or fell down this moment, the dumping switch contact of connecting in the loop disconnects, the cut-off loop electric current, the magnetic valve return is closed source of the gas, reach the flame-out purpose that ensures safety, according to present technical merit, domestic one pole E type thermocouple output is maximum, when 650 degrees centigrade of Chang Minghuo flames, can reach about 20MV, system's internal resistance is at 80-150M Ω, and in the constant situation of electromotive force V, internal resistance is larger according to Ohm's law I=V/R, electric current in the loop is less, when loop current during less than the maintenance electric current of magnetic valve, solenoid electric valve just can not by adhesive, cause gas circuit not opened.So such situation will appear in existing pouring protecting device, in use for some time, stove and accessory sparking will occur and can fire to loose one's grip and just go out, phenomenon that can not self-insurance.The reason that this phenomenon occurs be exactly topple in the protection system internal resistance in use; gradually internal resistance increases; when the internal resistance of system increases to a certain degree; toppling over the electric current of protection in the loop will reduce, when being reduced to a certain degree, when keeping electric current less than solenoid electric valve; solenoid electric valve just can not adhesive; the gas circuit of not opening does not have fuel gas supply like this, naturally beats missing of ignition.The reason that system's internal resistance increases has: 1, and connect skewer spare contact internal resistance oxidation and become large.2, it is large that the internal resistance oxidation of normally closed type anti-tilt switch contact becomes.3, stove and accessory is at the circuit systemic contamination, and is dirty.
Take fuel gas heating apparatus as example: a lot of warmers just occur striking sparks and firing after using one or two years; loose one's grip and just go out; phenomenon that can not self-insurance; main cause is that system's internal resistance increases; loop current keeps electric current less than solenoid electric valve; make the solenoid electric valve of toppling in the protector can not adhesive, affect the unimpeded reason of gas circuit.
Summary of the invention
The purpose of this invention is to provide a kind of parallel combustion gas and topple over break off preventor, solved that internal resistance in the circuit increases and the problem that causes the combustion gas gas circuit not opened.
In order to achieve the above object, the present invention has following technical scheme:
Break off preventor is toppled in a kind of parallel combustion gas of the present invention; comprise solenoid electric valve; dumping switch; the anoxic protector; described dumping switch is normally opened contact formula dumping switch; this normally opened contact formula dumping switch and battery are cascaded first, then are connected in parallel on again the two ends of solenoid electric valve, and solenoid electric valve is in parallel with the anoxic protector.
Wherein, described battery is a 1.5V dry cell.
Wherein, the described parallel combustion gas circuit tie point of toppling over break off preventor all adopts soldering to connect.
Owing to taked above technical scheme, the invention has the advantages that:
1 the present invention is exactly that closed type dumping switch with prior art has changed normally opened contact formula dumping switch into, and increases the dry cell of a 1.5V, solved in the circuit like this, and the problem that increases of normally-closed contact formula dumping switch internal resistance.
2 in order to guarantee accurate sensitivity of the present invention, and the tie point of circuit of the present invention all adopts soldering to connect, and so just solved the disadvantage that prior art adopts the oxidation of skewer spare tie point that internal resistance is increased.

The specific embodiment
Following examples are used for explanation the present invention, but are not used for limiting the scope of the 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; the anoxic protector forms, and described dumping switch is normally opened contact formula dumping switch, and this normally opened contact formula dumping switch and a 1.5V battery are cascaded first; then be connected in parallel on again the two ends of solenoid electric valve, solenoid electric valve is in parallel with the anoxic protector.
The circuit tie point that break off preventor is toppled in described parallel combustion gas all adopts soldering to connect.
Under normal circumstances, press the shift knob of gas utensil, beating Chang Minghuo, Chang Minghuo burns ODS, heats to ODS, will produce an electromotive force in the ODS circuit, this electromotive force will adhesive be connected on the coil of the solenoid electric valve in the circuit, like this solenoid electric valve adhesive, gas circuit conducting, flame combustion, the gas utensil normal operation.When gas utensil tilts or falls down; normally opened contact formula dumping switch is closed; circuit is connected; the 1.5V dry cell that is connected in parallel on the solenoid electric valve two ends can add a reverse potential within the Electromagnetic Control valve coil short time; the solenoid electric valve electric current is dropped to keep below the electric current; and make solenoid electric valve break away from adhesive, thereby the gas circuit of closing reaches the purpose of blowout protection.
In concrete operation; it is slightly different from the installation of toppling over protector of prior art that the mounting means of break off preventor is toppled in parallel combustion gas of the present invention: at first the ODS solenoid electric valve is installed on the boxboard; their shell end common ground (shell); they are actually and are installed in parallel; in the situation of pipeline UNICOM; can put catches fire carries out work, and the two ends of then receiving respectively the Electromagnetic Control valve coil with two remaining lines after 1.5 volts of dry cells of joint and the dumping switch open in usual series connection get final product.Stir movable contact it is contacted with stationary contact, solenoid electric valve namely cuts out flame-out, as not flame-out, the battery polar reversal connection is got final product.
Obviously, above-mentioned example of the present invention only is for example of the present invention clearly is described, and is not to be restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give all embodiments exhaustive.Everyly belong to the row that apparent variation that technical scheme of the present invention extends out or change still are in protection scope of the present invention.
