Positive pressure deflating valve

Abstract

The invention discloses a positive pressure deflating valve, comprising a valve body; a coil assembly part, a sensitive part and a magnetic conducting part are arranged on the valve body, wherein the coil assembly part comprises a coil arranged in the valve body, and a second joint and a third joint arranged at one side of the valve body, as well as an electrode arranged at the other side of the valve body; the sensitive part comprises a fixed bracket arranged in the valve body, a plastic bracket is arranged in the fixed bracket, a through hole is arranged in the middle of the fixed bracket, an air hole is arranged on the plastic bracket; the magnetic conducting part comprises a first joint arranged at the other side in the valve body, as well as a magnetic conducting pipe and a magnetic conducting plate, which are arranged in the valve body, one end of the first joint, close to the sensitive part, is internally provided with a copper needle, a spring is arranged between the first joint and the sensitive part, and the spring is sheathed on the copper needle. The opening degree of the deflating valve is controllable, so that pressure difference in a gas pipeline changes slowly and other sensors are protected to work normally. The switching valve is simple to manufacture and easy to control and can be widely adopted.

Description

technical field [0001] The invention relates to a positive pressure air release valve based on pulse width regulation, which belongs to an actuator for controlling a supercharger and a two-stage supercharging on an engine. Background technique [0002] The supercharger uses the inertial momentum of the exhaust gas discharged from the engine to drive the turbine, the turbine drives the impeller, and the impeller presses the air sent by the air filter pipe to pressurize it into the cylinder. The solenoid valves used in the previous technology to control the pressure of the exhaust gas from being too high are all switch-type, which only function as a switch to make the gas on and off to discharge, but it cannot make the opening of the exhaust valve controllable. Turning into a switch value will cause the deflation to be too fast, and the pressure difference will increase instantly, which will damage the sensors of other mechanisms. Contents of the invention [0003] The purp...
