Technical Field

The invention relates to the technical field of electromagnetic valves, in particular to a high-temperature resistant electromagnetic valve.

Background

The high-temperature electromagnetic valve is widely applied to the field of automatic control of pipeline media in military industry, aerospace industry, ship heavy industry, nuclear industry and the like. But high temperature solenoid valve's life is lower, and when the medium passed through in the solenoid valve, the heat that the high temperature medium gived off can pass through armature and transmit to on the solenoid, and then makes solenoid's temperature constantly rise, and until solenoid's insulating crust by the melting capacity, solenoid short circuit, burn out to make solenoid scrap, high temperature solenoid valve unable normal work. On the other hand, the control of the electromagnetic valve on the gas flow affects the stable operation of the propeller.

Therefore, improvements are made to the above problems.

Therefore, the invention aims to solve the problem that the electromagnetic coil of the electromagnetic valve in the prior art is easy to burn out, and is realized by the following technical scheme:

a high temperature resistant solenoid valve comprising: the electromagnetic part, the radiating pipe, the valve rod, the vent pipe, the Peltier module, the valve seat and the valve clack; the electromagnetic part comprises a plurality of electromagnetic coils capable of working independently, the number of the vent pipes is multiple, one end of each vent pipe penetrates through the armature and then is converged into a pipeline to continue to extend to the front of the return ejector rod, the other end of each vent pipe extends along the inner wall of the radiating pipe to extend to the valve seat, the radiating pipe is arranged between the electromagnetic part and the valve seat, the outer wall surface of the radiating pipe is provided with a Peltier module, and the Peltier module is connected with an electric power storage module; the Peltier module converts heat on the radiating pipe into electric energy through a thermoelectric effect and stores the electric energy.

The invention has the following beneficial effects:

1. the vent pipe is arranged by extending and converging a plurality of pipes into one pipe, so that high-temperature gas is dispersed and enters the vent pipe, the gas is fully radiated before entering the vent pipe in the cavity, the heat radiated to the armature is reduced, the temperature of the electromagnetic coil in the use process is reduced, the possibility of melting an insulating sheath of the electromagnetic coil in the use process is reduced, and meanwhile, the vent pipe in the cavity is arranged in an intersecting manner, so that the dispersed gas is concentrated, the action on the return ejector rod is better, the gas pressure is concentrated above the cavity, the armature is pressurized downwards, and the sealing effect of the valve clack is further improved.

2. According to the invention, the plurality of independently working electromagnetic coils work alternately, so that a single electromagnetic coil does not work for a long time, the heat generated by the electromagnetic coil due to long-time work is further reduced, and the service life of the electromagnetic coil is further prolonged.

3. According to the invention, the arrangement of the Peltier module on the peripheral wall of the radiating pipe can be used for absorbing the heat around the radiating pipe and storing the heat into electric energy, so that the heat emitted by high-temperature gas can be effectively utilized.
