Ultrahigh-temperature, high-pressure, large-flow and quick-response electromagnetic valve

Abstract

The invention provides an ultrahigh-temperature high-pressure large-flow quick response electromagnetic valve which comprises a movable valve element assembly, a magnetism isolating pipe assembly and a coil assembly, the movable valve element assembly comprises a center pipe, an upper movable iron core and a lower movable iron core, and a magnetism isolating ring is installed between the upper movable iron core and the lower movable iron core; the plunger tube assembly comprises 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 comprises an upper coil corresponding to the upper movable iron core, a lower coil corresponding to the lower movable iron core, a first magnetic conductive plate and a second magnetic conductive plate, the first magnetic conductive plate and the second magnetic conductive plate are arranged on the two sides of the lower coil, a magnetic isolation piece is installed between the upper coil and the lower coil, and a third magnetic conductive plate is arranged at the lower end of the upper coil. The first magnetic conductive plate and the third magnetic conductive plate are located on the two sides of the magnetic isolation piece respectively. The ultrahigh-temperature, high-pressure, large-flow and quick-response electromagnetic valve overcomes the defects that an existing electromagnetic valve is long in opening and closing response time and not suitable for the high-temperature and high-pressure environment.

Description

technical field [0001] The invention relates to the field of electromagnetic valves, in particular to an ultra-high-temperature, high-pressure, large-flow, quick-response electromagnetic 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. When the medium is ultra-high temperature and high pressure, all the components inside the solenoid valve will be If 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 deform due to the high temperature. [0003] Existing solenoid valves are only suitable for fuels, such as natural gas, coal gas, gasoline, diesel and kerosene, etc. Solenoid valves are used to control the on-off of these fuels, and the switching of solenoid valves requires a process. It requires multiple processes suc...
