An ultra-high temperature, high pressure and large flow rapid response solenoid valve

Abstract

The invention provides an ultra-high temperature, high pressure and large flow rapid response solenoid valve, which includes a movable valve core assembly, a magnetic isolation tube assembly and a coil assembly. The movable valve core assembly includes a center tube, an upper movable iron core and a lower movable iron core. A magnetic isolation ring is installed between the iron core and the lower movable iron core; the magnetic isolation tube assembly includes an upper fixed iron core arranged opposite to the upper movable iron core and a lower fixed iron core arranged opposite to the lower movable iron core; the coil assembly includes a The upper coil corresponding to the upper movable iron core, the lower coil corresponding to the lower movable iron core, and the first magnetic conductive plate and the second magnetic conductive plate arranged on both sides of the lower coil, and a magnetic isolation is installed between the upper coil and the lower coil. The lower end of the upper coil is provided with a third magnetic conductive plate, and the first magnetic conductive plate and the third magnetic conductive plate are respectively located on both sides of the magnetic isolation member; the invention provides an ultra-high temperature, high pressure and large flow rapid response solenoid valve, It overcomes the defects of the existing electromagnetic valve having a long opening and closing response time and being unsuitable for a high temperature and high pressure environment.

Description

technical field [0001] The invention relates to the field of solenoid valves, in particular to an ultra-high temperature, high pressure and large flow rapid response solenoid valve. Background technique [0002] The applicable medium of the existing solenoid valve is usually neutral gas and neutral liquid, the seal is mainly made of rubber, and the special medium is supplemented by engineering plastics. All fail, the coil will burn out due to the high temperature, the seal will melt due to the high temperature, and the material will be deformed due to the high temperature. [0003] The existing solenoid valve is only suitable for fuel, such as natural gas, gas, gasoline, diesel and kerosene. It requires multiple processes such as ignition, combustion and injection. The addition of these links will lead to too long reaction time, and it is impossible to achieve a rapid orbit change of a high-speed flying object. This problem has always been an urgent problem for us to solve....
