Bidirectional throttle valve and air conditioner

The bidirectional throttle valve comprises a valve seat and a valve element assembly, the valve seat is provided with a first valve port, a second valve port and a throttle channel, the valve element assembly is arranged in the valve seat, the valve element assembly comprises a first valve element, a second valve element and a transmission part, and in the first state, the first valve element is connected with the second valve port through a first valve element, and the second valve element is connected with the transmission part through a second valve element. In the first state, the first valve element blocks the first valve port, the second valve element blocks the second valve port, in the second state, the first valve element opens the first valve port, and the second valve element opens the second valve port. According to the two-way throttling valve, two-way throttling can be achieved easily and conveniently, adjustability of the two-way throttling valve is improved, universality of the two-way throttling valve is improved, in the same throttling channel, flow limitation caused by separation of the throttling channel is avoided, the structure of the throttling channel is simplified, meanwhile, use of parts is reduced, and cost is reduced. The production cost is reduced, and the assembly efficiency is improved.
