A Cylinder Valve Realizing Intelligent Control

Abstract

The invention discloses a gas cylinder valve realizing intelligent control. The valve body is provided with an air inlet hole, an interception hole, a valve cavity hole, a threaded hole, and a valve core hole connected in sequence. The valve core is installed in the valve body and can be installed along the thread The hole rotates and translates, the valve cavity hole is connected to the valve body through the air outlet hole, the front end of the valve core can move to the air intake hole to block the interception hole, and can also move to the rear end of the valve body, so that the valve cavity hole is connected to the air intake hole, and the rear end of the valve core Driven by the turbine, the turbine meshes with the worm, the worm is driven by the deceleration motor, the deceleration motor is connected with the controller signal, and the start and stop of the deceleration motor is controlled by the locked-rotor current, so that the valve core moves back and forth. It is safe and reliable to use on the train, and realizes automatic remote control.

Description

technical field [0001] The invention relates to the technical field of gas cylinder valves, in particular to a gas cylinder valve for vehicles which can realize intelligent control. Background technique [0002] At present, in the traditional gas cylinder valves, the opening and closing functions of the valve are basically realized by manual and electromagnetic methods, which require personnel to operate close to the valve, and it is difficult to realize intelligent control, and the valve closing is prone to misoperation, resulting in the valve not being completely closed and causing leakage. security risks. The traditional gas cylinder valve sealing method has no compensation structure, which will cause valve leakage after the sealing ring is worn. Traditional gas cylinder valves generally have a single flow channel. When multiple flow channels are required, multiple valves must be installed on the gas cylinder, which requires more openings on the gas cylinder, which invis...

Problems solved by technology

[0004] Vehicle liquid ammonia steel cylinders are installed in motor vehicles to treat exhaust gas. The injection of liquid ammonia needs to be continuously controlled by the ECU according to the speed and torque of the vehicle engine. The state will cause the coil to overheat and burn, and liquid ammonia is a poisonous and dangerous product. When the solenoid valve fails, it will cause excessive ammonia injection or spray ammonia when the car is not in use. It is necessary to develop and design "a gas cylinder that realizes intelligent control." "Automatic control valve" replaces the solenoid valve control spool to meet the safe and stable supply of gas in the cylinder and prevent leakage
