Abstract

The invention provides a novel pressurized flushing and discharging valve device for a closestool. The device is composed of the main components including a cam mechanism, an air cylinder, a discharge valve, a one-way valve and the like. A cam is simple in structure, pure mechanical pressurized water is adopted for flushing a closestool bowl and controlling the opening and closing of the drainage valve, so that the traditional water pressurizing device and pneumatic discharging valve which are driven by compressed air are replaced, and the air consumption amount is greatly reduced. For the device, a stepping motor drives the cam mechanism, water pumping and pressurization work is completed through reciprocating motion of a piston, and meanwhile, the discharge valve is controlled to be opened and closed synchronously; the device is simple, and is easy to operate and low in energy consumption.

Description

technical field [0001] The invention discloses a mechanical pressure flushing and discharge valve device. Background technique [0002] Drain valves and water pressurized flushing devices are an essential part of the water supply sanitation systems for ordinary passenger trains and EMUs. The discharge valve is used to control the connection between the bedpan and the vacuum pipeline. When the flush button is pressed, the discharge valve opens, and the negative pressure in the dirt tank (middle box) and the pipeline sucks out the waste from the bedpan, and then the discharge valve closes. It is compressed air to control the opening and closing of the valve. The water pressurization unit also controls the inhalation and pressurization of the flushing water in the water booster tank by compressing the gas, so as to realize the function of flushing the bedpan. The realization of the above two functions will inevitably consume a large amount of compressed air, and because the e...
