Abstract

The invention relates to a rotary and sealed water and air bi-pass device. The rotary and sealed water and air bi-pass device is characterized by comprising a central spindle, a central spindle sleeve, a water inlet end bearing seat, and a water inlet end bearing; the upper end of the central spindle is fixed on the water inlet end bearing seat through positioning holes on the central spindle; the lower end of the central spindle is extended into the central spindle sleeve; a seal ring for a shaft is arranged between the upper end of the central spindle and the upper end of the central spindle sleeve; a pair of O-shaped rubber rings is arranged between the lower end of the central spindle and the lower end of the central spindle sleeve; an air passage is formed in the middle of the central spindle; a water passage is formed on the periphery of the air passage; the upper end of the air passage is connected with an air inlet pipe; the lower end of the air passage is communicated with anair cavity on the central spindle sleeve; the central spindle sleeve is provided with a water outlet which is communicated with the water passage and is communicated with a water outlet pipe; and theupper end the central spindle sleeve is closely connected with the water inlet end bearing seat through a pair of water inlet end bearings. The central spindle sleeve of the device can rotate, and the air way and the water way exist together and are not influenced mutually.

Description

technical field [0001] The invention belongs to the technical field of a rotatable water-air double-pass mechanical component used between a water inlet pipe and a water outlet pipe of passenger train water supply equipment, and in particular relates to a rotatable and sealed water-air double-way device. Background technique [0002] In the past, the whole process of adding water to train water tanks was done manually, which was labor-intensive, took a long time, seriously wasted water resources, and polluted the environment. Contents of the invention [0003] The object of the present invention is to provide a rotatable and sealed water-air double-way device, the mandrel sleeve of the device is rotatable, and the water passage and the air passage coexist but do not affect each other. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a rotatable and sealed water-air double-way device, which is characterized in that i...
