Active control type air valve plate

Abstract

The active control type air valve plate comprises a bottom plate, a control unit and an air path unit are installed on the bottom plate, and the air path unit comprises an air inlet, a filter valve, apantograph rising electromagnetic valve, a pressure regulating valve, a high-frequency valve I, a high-frequency valve II, a safety valve, a pressure sensor I, a pressure sensor II, an air outlet, afeedback port and a pressure switch. The filter valve, the pantograph lifting electromagnetic valve and the pressure regulating valve are respectively fixed on the bottom plate; the high-frequency valve I, the high-frequency valve II, the safety valve, the pressure sensor I and the pressure sensor II are fixed on the bottom plate through the gas circuit block I; the pressure switch is fixed on thebottom plate through a gas circuit block II; the air outlet is formed in the air path block I, and the feedback port is formed in the air path block II. According to the invention, the average dynamic pressure of the pantograph and the contact network can be adjusted in real time, and the pantograph control unit can monitor the gas circuit in real time.

Description

technical field [0001] The invention relates to an actively controlled air valve plate. Background technique [0002] The existing pantograph air valve plate does not have active control functions, and is generally integrated with electromagnetic valves, filter valves, bow throttle valves, precision pressure regulating valves, bow throttle valves and safety valves, etc., which can be used for pantograph Air supply, control pantograph lifting and contact pressure adjustment. This type of valve plate is generally used in the middle and low speed grades of ≤250km / h. [0003] The stability of the current receiving quality of high-speed EMUs depends on the dynamic pressure of the pantograph and the catenary, and the dynamic pressure requirements change at different speed levels, especially for high-speed pantographs with a speed level of ≥300km / h. However, The existing pantograph air valve plate cannot realize the real-time adjustment of the average dynamic pressure of the pant...

[0003] The stability of the current quality of high-speed EMUs depends on the dynamic pressure of the pantograph and the catenary, and the dynamic pressure requirements vary at different speed levels, especially for high-speed pantographs with a speed level of ≥300km / h. However, The existing pantograph air valve plate cannot realize the real-time adjustment of the average dynamic pressure of the pantograph and catenary, nor can it realize the real-time monitoring of the gas circuit by the pantograph control unit
