Abstract
The utility model relates to an automatic cut-off gas valve used for a gas range, which is provided with an electromagnetic valve, a delay switch 9 and a temperature sensor 15; the electromagnetic valve, the delay switch 9 and the temperature sensor 15 are mutually connected, wherein, the electromagnetic valve is arranged in a gas pipeline 4 connected with a range; the temperature sensor is fixed in a stove core of the range. The utility model has the advantages that the operation is convenient, the utility model can automatically cut off a gas source under the condition of the abnormal condition, and the gas leakage, gas poisoning and fire can be avoided, etc.
Description
The utility model is a kind of automatic cut-out gas valve that is used for gas kitchen ranges.
Use gas-cooker such as gas range in the kitchen, unmanned on the scenely extinguishes because of improper use or because of spilling water or by abnormal conditions such as wind often, unburned coal gas leaks, and causes gas poisoning or causes that accident such as fire constantly takes place.
The purpose of this utility model provides a kind of automatic cut-out gas valve, solves when the coal gas unburned leaks and can close source of the gas automatically, with the problem that prevents that accident from taking place.
The purpose of this utility model is that sample is realized: be provided with magnetic valve, delay switch and heat detector, the three links to each other with lead, and in the gas pipeline that magnetic valve is contained in kitchen range link to each other, heat detector is fixed on the sidepiece place of kitchen range inner stove core.
Operation principle of the present utility model is: be subjected to the variation of kitchen range temperature to control the action of magnetic valve, source of the gas is closed.
The utlity model has easy to usely, dependable performance is met abnormal conditions and can in time be cut off source of the gas automatically, can avoid that coal gas leaks, advantages such as gas poisoning and initiation fire.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the utility model structural representation.
As shown in the figure, structure of the present utility model is: be provided with magnetic valve, delay switch 9, heat detector 15, the three links to each other with lead.And magnetic valve is contained in the Gas Pipe road 4 that links to each other with combustion gas (coal gas) kitchen range.Heat detector is fixed on the sidepiece of kitchen range inner stove core 13.
In the above-mentioned magnetic valve, be provided with solenoid 1, spring 2 and valve body 3.Valve body is made up of shell, spool 5 and axle 8, and spool is Rotary-table and the inner chamber 6 that is arranged in shell, and inner chamber communicates with the mouth of pipe 7 of gas pipeline 4; Axle is connected as a single entity with spool, and its upper end is stretched in the solenoid; Spring housing is on axis body, and its lower end and axis body are worn and connected.Solenoid shell and valve shell are connected as a single entity with gripper shoe or bracing frame etc.
Solenoid 1 contact a, heat detector 15 contact c, delay switch contact f link to each other, and heat detector contact d, delay switch contact e, contact of power supply link to each other, and solenoid contact b links to each other with another contact of power supply, and the line that is positioned at kitchen range all puts porcelain tube 16.In order to prevent electric leakage, can allow kitchen range ground connection.Button 10 is contained on the shell of delay switch, and they can be contained on the kitchen range shell, for example the ignition switch place.Power supply can adopt civil power 220V power supply.Sequence number the 11, the 12nd in the accompanying drawing, and kitchen range air inlet pipe, sequence number 14 are the outer combustion chambers of kitchen range.
Above-mentioned heat detector and delay switch can be made by oneself, also can buy from the market, and for example heat detector then can be selected the heat detector of electric cooker, refrigerator for use.
The course of work of the present utility model is: in the time will cooking or heat up water, can press the button 10, make the closing of contact of delay switch 9 inside, then magnetic valve gets electric startup, moves on the spool 5, so gas pipeline 4 air flues are connected and supplied gas, this moment, spring 2 was in compressive state.Then, opening the igniting of kitchen range ignition switch gets final product.Along with the kitchen range temperature rises, the closing of contact of heat detector 15 inside, itself and delay switch send side by side.In the time of setting, generally be set at 3-5 minute, throw off automatically the delay switch contact, by the heat detector holding circuit work hard in glove with make magnetic valve be in electricity condition.
If cooking finishes or because of reasons such as spilling water cause flame-outly, this moment, kitchen range temperature descended, the heat detector contact disconnects, the magnetic valve dead electricity, and spring reset make spool move down the sealing mouth of pipe 7, thereby the cut-out source of the gas reaches the purpose that prevents the accident generation.
