Electronic control electromagnetic relief valve with good sealing performance

Abstract

The invention discloses an electronic control electromagnetic relief valve with good sealing performance. The electronic control electromagnetic relief valve comprises a valve body with an electronic control socket, a static iron core is arranged at the bottom of the valve body, a magnetic conductive plate is arranged at the periphery of the bottom of the static iron core, a coil holder matched with the static iron core is arranged at the upper part of the magnetic conductive plate, and a coil winding is arranged at the upper part of the coil holder; a movable iron core corresponding to the static iron core is arranged at the top of the valve body, the top of the movable iron core is fixedly connected with a sealing cover through a movable iron core gasket, and a magnetic conductive cover plate matched with the magnetic conductive plate is arranged at the periphery of the middle part of the movable iron core; a ring body is embedded at the periphery of the top of the sealing cover; and the periphery of the ring body is wrapped with a heat-resistant rubber layer or a polytetrafluoroethylene layer. After the exterior of the ring body provided by the invention is wrapped with the heat-resistant rubber layer or the polytetrafluoroethylene layer, the sealing performance and the using condition adaptability of an original sealing cover are improved completely.

Description

technical field [0001] The invention relates to an electronically controlled electromagnetic pressure relief valve for a supercharger with good sealing performance. Background technique [0002] At present, turbocharging technology is being favored by more and more manufacturers. Because it can effectively improve engine efficiency, it has become one of the mainstream trends in energy conservation and environmental protection in the current gasoline energy era. A supercharged engine with a throttle, especially a gasoline engine that uses supercharging technology to work, when the accelerator pedal is suddenly released, a near-closed gap will suddenly form between the outlet of the turbocharger compressor and the throttle. volume, while the impeller in the compressor still feeds the pressure cable air into the intake pipe due to the rotating inertia. At this time, the outlet pressure of the compressor rises and the air flow decreases, which easily causes the turbocharger to ...

Problems solved by technology

Because it is relatively hard, it is easy to deform after long-term use at high temperature, resulting in increased leakage. It is not suitable to control the size of the leakage, and it is impossible to achieve rapid pressurization or decompression.
