Abstract
The invention discloses a cleaning method and device for a channel of a valve body inner cavity. The cleaning method for the channel of the valve body inner cavity comprises, firstly, connecting an outlet end of the channel of the valve body inner cavity with an opening and closing device through a pipeline and enabling the powering on and the powering off of the opening and closing device to be controlled through a pressure sensing device; secondly, communicating an inlet end of the channel of the valve body inner cavity with a high pressure cleaning fluid source or a high pressure air source and enabling a pressure sensing end of the pressure sensing device to be capable of sensing pressure in the channel of the valve body inner cavity. When the pressure of the channel of the valve body inner cavity is larger than a pressure value set by the pressure sensing device, the opening and closing device is opened, a strong cleaning fluid flow or air flow can be formed in the channel of the valve body inner cavity to burst out of a channel outlet and carry away sewage inside the valve body inner cavity. According to cleaning method and device for the channel of the valve body inner cavity, by means of pulse type high-pressure cleaning, the aim of cleaning the channel of the valve body inner cavity can be achieved. The cleaning method and device for the channel of the valve body inner cavity has the advantages of being high in cleaning efficiency, good in cleaning effect, simple in structure and convenient to operate. The cleaning method and device for the channel of the valve body inner cavity is particularly applicable to cleaning air brake control valves used in existing railway vehicles.
