The invention provides a rail transit train, an air conditioner and an air valve. The air valve comprises a valve body, a fresh air valve body, an air return valve body and a linkage assembly. A freshair channel and air return channels are formed in the valve body, the two ends of the fresh air valve body are rotationally arranged in the fresh air channel, and the two ends of the air return valvebody are rotationally arranged in the air return channels; an external executing mechanism drives the linkage assembly to control the fresh air valve and the air return valve to act in a linkage mode, so that the fresh air channel is opened and the air return channels are closed, or the fresh air channel is closed and the air return channels are opened, or the fresh air channel and the air returnchannels are opened simultaneously. The valve body synchronously controls the fresh air valve body and the return air valve body through the linkage assembly, simultaneous or alternate opening and closing control over the fresh air channeand the return air channel through one driving mechanism is achieved, alternate introduction of fresh air and return air is achieved, the passenger riding experience is improved, space is saved, and cost is reduced. The invention further provides a rail transit train and an air conditioner.
Description
technical field [0001] The invention relates to the technical field of rail transit trains, and more specifically, relates to a rail transit train, an air conditioner and an air valve. Background technique [0002] In the prior art, air conditioners in urban rail transit trains often have different requirements for return air volume and fresh air volume, and are often controlled by independent air valves and actuators, which will occupy space in the car and cause cost increases. [0003] Therefore, how to provide a damper so that one driving mechanism can simultaneously control the fresh air and the return air is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the present invention provides an air valve to realize the simultaneous control of fresh air and return air by one driving mechanism; the present invention also provides a rail transit train and an air conditioner. [0005] In order to achieve the above...
