Abstract

The invention relates to electromagnetic valves, in particular to a high-reliability integrated electromagnetic valve for controlling an ESD valve of a gas turbine power plant. The problem that an existing ESD valve control technology is poor in control reliability is solved. The high-reliability integrated electromagnetic valve for controlling the ESD valve of the gas turbine power plant comprises a base, a top seat, a left electromagnetic reversing valve and a right electromagnetic reversing valve, wherein the base is of an L-shaped blocky structure; the top seat is of a rectangular blocky structure; the base and the top seat are spliced together to form a U-shaped valve seat with a leftward opening; and a first U-shaped gas channel, a second U-shaped gas channel, a first L-shaped gas channel and a second L-shaped gas channel are formed in the base. A third U-shaped gas channel, a fourth U-shaped gas channel, a third L-shaped gas channel, a first straight gas channel, a second straight gas channel and a third straight gas channel are formed in the top seat. The left electromagnetic reversing valve and the right electromagnetic reversing valve are assembled in the opening of the U-shaped valve seat side by side. The high-reliability integrated electromagnetic valve is suitable for the gas turbine power plant.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to a high-reliability integrated solenoid valve for controlling an ESD valve in a gas turbine power plant. Background technique [0002] In a gas-fired power plant, when the gas-fired unit suddenly fails or the equipment in the natural gas pressure regulating station suddenly leaks, it is necessary to quickly close the ESD valve (emergency shutdown valve) on the natural gas pipeline, thereby shutting down the natural gas source in an emergency, so as to ensure The safety of the equipment in the gas unit or natural gas pressure regulating station. At present, the opening and closing action of the ESD valve is controlled by a single electromagnetic reversing valve (the electromagnetic reversing valve is a two-position five-way electromagnetic reversing valve). The specific control method is as follows: First, the staff controls the electromagnetic reversing valve to be energized through an externa...
