Embodiment Construction

[0019] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] The specific embodiment of the quick response electromagnetic valve of the present invention, this is as figure 1 As shown, the quick-response solenoid valve is a solenoid valve used in the air supply and braking system of rail transit vehicles, and is used to charge and exhaust air for downstream equipment. The quick-response solenoid valve includes a valve body 1. The valve body 1 is L-shaped as a whole. The lower end of the horizontal section is provided with an air source inlet 7 and a product outlet 8. The air source inlet 7 is used to connect the air source or air supply source, and the product outlet 8 is used In connection with the downstream equipment, the upper part of the vertical section of the valve body 1 is provided with a vent 9, and the vent 9 directly communicates with the atmosphere. The vertical section of the valve body 1 is ...

Abstract

The invention relates to a fast response electromagnetic valve. According to the fast response electromagnetic valve, a magnetic isolation part is arranged between matching ends of a movable iron coreand a static iron core and / or at least one of the two matching ends, when an electromagnetic coil is electrified, the voltage is large, the magnetic separation part does not influence the rapid attraction between the movable iron core and the static iron core, when the electromagnetic coil is powered off, due to the fact that the voltage is gradually reduced, the magnetic isolation piece can be used for cutting off the magnetic flux between the movable iron core and the static iron core, or enabling a magnetic induction wire to be transmitted by bypassing the magnetic separation part, so thatthe electromagnetic force between the movable iron core and the static iron core is reduced, so that the acting force of the spring can be larger than the electromagnetic force in a short time afterthe electromagnetic coil is powered off so as to enable the movable iron core quickly responding, the purpose of improving the response speed of the electromagnetic valve is achieved, and the safety application of the electromagnetic valve in a scene needing rapid response is ensured.

Description

technical field [0001] The invention relates to a quick response solenoid valve. Background technique [0002] General electromagnetic valve is made up of electromagnetic coil, static iron core, spring, movable iron core and valve body etc. There are air inlets, air outlets and air vents. There is a spool cavity in the valve body. Inside the spool cavity is a stopper (equivalent to a static iron core) and a valve core (equivalent to a moving iron core). The gap between the valve core and the valve seat is There is a spring between them, the valve seat is provided with an air intake channel connected with the air intake port, the outlet of the air intake channel is a seal (equivalent to the second control valve port), the moving iron core seals it through the front sealing block, A ventilation passage is formed between the outer circumference of the moving iron core and the inner wall of the valve core cavity, the ventilation passage communicates with the air outlet, the sto...
