A High Pressure Electric Control Valve for Underwater

Abstract

The invention belongs to the technical field of control devices, and particularly relates to a high pressure electric control valve used underwater. The high pressure electric control valve used underwater comprises a shell, a coil body, an iron core, a motion control sleeve, a reset spring, a slide valve, a gas circuit base and a center rod; the coil body comprises two contact pins, a framework, a coil, an outer casing, an inner casing and a check ring; after being assembled with an air-blast sound source, the electric control valve is arranged under water in a certain depth to work. Under the control of a control unit, enough magnetic field force can be produced inside the electric control valve to drive a motion controller to drive the slide valve to do the corresponding motion for opening an internal gas circuit channel, so that the gas inside a gas storage chamber can enter the air-blast sound source to control work through a valve gas outlet. When the control unit is under the disconnected state, the magnetic field inside the electric control valve disappears, and under the elastic force of the reset spring, the slide valve closes the internal gas circuit. The high pressure electric control valve used underwater provided by the invention can simultaneously open or close a plurality of electric control valves under the control of electric signals, so as to realize the aim of controlling a plurality of air-blast infrasonic minesweeping gears to blast simultaneously.

Description

technical field [0001] The invention belongs to the technical field of control devices, and in particular relates to an underwater high-pressure electric control valve. Background technique [0002] The detonation sound source currently equipped on a certain type of minesweeper is a high-efficiency gas explosion sound source capable of generating infrasonic physical fields. Its infrasonic frequency radiation efficiency is high, the sound field energy level is large, and 80% of the energy is concentrated In the low frequency band below 20Hz, it has outstanding features such as small size, light weight, simple structure, convenient use, and low cost. However, the gas explosion sound source radiates a pulsed sound field, which makes the working mode of this single-pulse gas explosion sound source easy to be identified by mines, and its application range is limited. In order to overcome the defect of discontinuous sound field when the gas-explosion infrasonic mine-sweeping tool...

Problems solved by technology

[0006] According to data and domestic market research, there are currently many domestic units producing and manufacturing electric control valves or solenoid valves. There are many types and different forms, but there is no model for electric control valves suitable for underwater high pressure and impact resistance. Optionally, for this reason, as engineers and technicians engaged in this industry, it is necessary to explore, design, and manufacture a new type of electric control valve that can be used for underwater high pressure to meet the needs of engineers and technicians.
