The utility model discloses a kind of temperature constant solenoid valve, it relates to solenoid valve technical field, the solenoid valve includes, shell, static core, fixedly connected in shell, current coil, it is set to static core outside, valve body is located at shell bottom, and its valve cavity bottom is equipped with valve port, dynamic core bottom is located in valve cavity by elastic member, permanent magnet, it is embedded in static core outside in detachable mode, when current coil is electrified, static core adsorbs dynamic core and moves up to open valve port, when power off, permanent magnet adsorbs dynamic core and keeps open state, when current coil is electrified into reverse current, static core generates reverse magnetism, dynamic core moves down and seals valve port under the reset force of elastic member, the design utilizes permanent magnet, current coil and static core cooperation, can realize zero power consumption magnetic retention under power off, ensure that solenoid valve does not appear temperature rise phenomenon also makes its valve port long-time open, and then realize flow data accurate acquisition.

This invention discloses a core assembly and a method for manufacturing a stationary core for miniature circuit breakers, belonging to the field of circuit breaker technology. The core assembly includes a coil shell, a push rod, a stationary core, a moving core, and a spring. A stationary core is fixedly disposed inside the top of the coil shell, with a through hole at its center. The push rod slides through the through hole inside the stationary core. A moving core is disposed inside the bottom of the coil shell, with a spring between the moving core and the stationary core. The push rod passes through the through hole and the spring, abutting against the moving core, with a portion of the moving core inserted into the push rod. The through hole includes a first through hole, a second through hole, and a third through hole. When the push rod enters the stationary core, it passes through the first through hole, the second through hole, and the third through hole in sequence. This invention reduces the mutual collision between the push rod and the stationary core, preventing push rod breakage; it eliminates burrs, reduces friction between the push rod and the stationary core, reduces mutual collision, prevents push rod breakage, and increases the service life of the push rod and the core assembly.
