Abstract

The invention provides a locomotive electric pneumatic valve electromagnetic force measuring device which comprises a sliding groove fixing base, a sliding groove is formed in the left side of the sliding groove fixing base, the upper half portion of the sliding groove is connected with an electric pneumatic valve support, theelectric pneumatic valve support is equipped with an electric pneumaticvalve magnet yoke cylinder; a coil and a movable iron core and a static iron core are installed in the magnet yoke cylinder; the movable iron core is connected with a core rod; a patch board is also fixed on the outer side of the magnet yoke cylinder; a sensor support is arranged on the lower half portion of the sliding groove; and a tension and pressure sensor is installed on the sensor support.The device can be used under different working conditions, large errors caused by measurement data due to different working conditions during measurement are avoided, the measurement precision of themeasurement data under different working conditions is improved, and meanwhile, the relation between the electromagnetic force and related parameters of the locomotive electric pneumatic valve under different working conditions is measured.

Description

technical field [0001] The invention relates to the field of locomotive electropneumatic valves, in particular to an electromagnetic force measuring device for locomotive electropneumatic valves. Background technique [0002] The locomotive electro-pneumatic valve is an electrical device that controls the connection or cut-off of the compressed air pipeline of the locomotive by making the coil generate a magnetic field force through a DC power supply, so as to achieve remote control of the pneumatic device. It is widely used in the brake system of the locomotive and the bow control . [0003] In addition to the design of the structure, seal, flow channel, etc. necessary for the general valve of the locomotive electropneumatic valve, the most important thing is to design and check the suction force of the electromagnet. Generally, the weight of the electromagnet part of the electropneumatic valve accounts for 30% of the weight of the entire valve. ~40%, some are even higher,...
