Abstract

The invention belongs to the technical field of valves, particularly relates to an acting valve for unloading of a hopper car and solves the problem that simultaneous unloading of multiple coupled cars cannot be realized by the hopper car. The acting valve comprises a valve body, a lower body, a valve cover, a compression spring l, a core clamping valve, a valve seat, a valve rod, a membrane plate, a membrane retaining plate, a spring support, a compression spring II and a sealing ring, a wind-storing air chamber, a closed air chamber, a control air chamber and a cavity are arranged in the valve body, the wind-storing air chamber is provided with a wind-storing air inlet, the closed air chamber is provided with a bidirectional wind cylinder air inlet, the control air chamber is provided with a control pipe air inlet, the wind-storing air chamber, the closed air chamber and the control air chamber are communicated by a cavity, and each of the upper portion and the lower portion is provided with an opening. The acting valve can realize functions of simultaneous opening of bottom doors for unloading and simultaneous closing of the bottom doors of multiple rail coupled hopper cars.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a valve for unloading a hopper car. Background technique [0002] The unloading methods of the existing hopper trucks are mainly single wind and manual unloading, because the wind source pressure comes from the brake supervisor, and because there is no signal transmission for connecting multiple vehicles, it is impossible to realize simultaneous unloading of multiple connected vehicles. According to the influence of the operating conditions of railway freight cars in my country and the design specifications of the vehicles themselves, if the requirement of unloading multiple connected vehicles at the same time is realized, it is necessary to use the compressed air as the pneumatic unloading mechanism without changing the basis of the existing vehicle unloading opening and closing mode and transmission mechanism. The power source and signal source realize the opening and closing fun...
