Abstract
The utility model discloses a thermocouple for gas safety valves, which comprises a positioning cylinder. The front portion of the positioning cylinder is equipped with a thermal sensitive probe and the rear portion thereof is connected with a wiring sheet and a main coil plug-in unit of a solenoid valve. The main coil plug-in unit of the solenoid valve is in series connection with a pulse electricity plug-in unit. According to the technical solution of the present utility model, the main coil plug-in unit of the solenoid valve is in series connection with the pulse electricity plug-in unit, which is applied to the gas safety valve of the utility model. A pulse generator generates pulse current by connecting with the pulse electricity plug-in unit during the initial opening of the gas safety valve. The pulse current flows through the main coil plug-in unit of the solenoid valve to the main coil thereof, thereby enabling the main coil of the solenoid valve to be energized and at a closed state. In addition, the solenoid valve is turned on, gas can be smoothly transmitted to the burner. When the flame of the burner is stable, the thermocouple starts to work and supplies power for the solenoid valve. The trouble of manually hold-open state for a certain time during the first opening of the safety valve is omitted by using the above thermocouple for gas safety valves. The thermocouple adopts pulse power, which has a huge instantaneous current and a better effect, thus is more convenient in operation.
Description
Technical field
The utility model relates to a kind of gas-fired equipment, the thermocouple on the matching used safety valves for gas of especially a kind of burner.
Background technique
In the burner, the opening and closing of blast tube realize that by safety valves for gas tradition is used for the safety valves for gas of burner, all need manual spin safe valve core, and the angle of swing by spool changes and realizes ventilation or close gas.Because manual safety valves for gas, still not enough to some extent in Security, mainly be presented as and judge whether normal combustion of burner, therefore this situation of pin in the industry, newly released a class thermojunction type safety valve, its structure includes the valve body of charged magnet valve, solenoid valve connects a thermocouple, with the thermosensitive probe of thermocouple be installed in the matching used burner of safety valve on, manually open safety valve during use earlier, make combustion gas can be passed to the burner place and take fire, in combustion process, the heat transferred thermocouple of flame, the thermocouple generation electromotive force that is heated passes to solenoid valve through lead, makes solenoid valve be in opening state, guarantee the safety valve conducting, combustion gas can be passed to burner place normal combustion along blast tube, and after the flame extinction of burner, thermocouple can reduce and the attenuating electromotive force by Yin Wendu, make closed electromagnetic valve, and then cut off blast tube; The safety valve of this band thermocouple, increased the Security that combustion gas is used, be suitable for promoting, yet, because in initial ignition, thermocouple is subjected to flame heating, and the electromotive force that produce to need needs certain hour, if during this period of time staff leaves the manually opened place of safety valve, electric thermo-couple temperature is not enough, just can not guarantee the normal potential supply to solenoid valve, make safety valve close, gas supply will be disconnected; Therefore, present thermocouple safety valve all needs the user manually to stop certain hour in the enable possition of safety valve when first igniting, could decontrol after waiting flame holding, and is so, just inconvenient to some extent in the use.
Summary of the invention
At the problems referred to above, the utility model provides a kind of use more convenient, when opening safety valve for the first time, need manually not stop the thermocouple of certain hour in the open position of safety valve.
The utility model is that the technological scheme that its technical problem of solution is adopted is:
A kind of thermocouple that is used for safety valves for gas comprises location cylinder, and the location cylinder front portion is provided with thermosensitive probe, and the rear portion is connected with lug plate and solenoid valve main coil plug-in unit, and described solenoid valve main coil plug-in unit is serially connected with the Pulse Electric plug-in unit.
The beneficial effects of the utility model are: the utility model is connected in series the Pulse Electric plug-in unit on the circuit of solenoid valve main coil plug-in unit, be applied on the safety valves for gas, when the user opens safety valves for gas for the first time, the Pulse Electric plug-in unit can connect pulse oscillator and send impulsive current, be delivered to the solenoid valve main coil by magnet valve main coil plug-in unit, make solenoid valve main coil energising and being kept closed, solenoid valve conduction in addition, combustion gas just can be transferred on the burner smoothly, when the flame holding of burner, thermocouple is started working to solenoid valve; The utility model can save people need manually be held open the trouble of state certain hour when opening safety valve for the first time, and adopts Pulse Electric, and immediate current is big, and using effect is good, makes that the use of thermocouple is more convenient.
Description of drawings
Be described further below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1, a kind of thermocouple that is used for safety valves for gas, comprise location cylinder 1, location cylinder 1 can be used for thermocouple is installed on the burner, location cylinder 1 front portion is provided with thermosensitive probe 2, the flame that sends over against burner of thermosensitive probe 2 in use, so the heat that flame sends can pass to thermosensitive probe 2, location cylinder 1 rear portion is connected with lug plate 3 and solenoid valve main coil plug-in unit 4, after thermosensitive probe 2 is heated and produces electromotive force, can pass to solenoid valve, make solenoid valve work through solenoid valve main coil plug-in unit 4, wherein, described solenoid valve main coil plug-in unit 4 is serially connected with Pulse Electric plug-in unit 5.Location cylinder 1 is connected with solenoid valve main coil plug-in unit 4 by lead, and for guaranteeing heat resistance in the course of the work, lead 7 can adopt fluorine to mould line, and is covered with high temperature resistant sleeve pipe 6 in lead 7 external packets near location cylinder 1; In addition,, can not leak electricity or receive external environment influence, be provided with Pulse Electric plug-in jacket 51 outside the Pulse Electric plug-in unit 5, state the solenoid valve main coil plug-in unit 4 outer sheaths 41 that are provided with for making attachment security.
The utility model is on being used in burner the time, solenoid valve main coil plug-in unit 4 connects solenoid valve, Pulse Electric plug-in unit 5 is transferred to 4 effects of solenoid valve main coil plug-in unit with Pulse Electric, can select unlatching with solenoid valve as switch activated, when the people manually drives valve for the first time, the trigger generator origination point, owing to adopt Pulse Electric, power consumpiton is little, and the electric weight of moment can satisfy the demand of solenoid valve, makes scheme more reasonable; When the flame holding of burner, thermocouple is started working to solenoid valve, but the just supply of stop pulse electricity this moment, and in actual the use, this process is the time in several seconds, therefore can realize by the output of time control pulse electricity.
As fully visible, the utility model can save people need manually be held open the state certain hour when opening safety valve for the first time trouble, uses more convenient.
