Throttle valve and air conditioning system with same

The utility model provides a throttle valve and an air conditioning system with the same, the throttle valve comprises a valve seat, a first valve port, a second valve port, a first flow channel and a second flow channel are formed in the valve seat, one end of the first flow channel is connected with the first valve port, and one end of the second flow channel is connected with the second valve port; the valve element assembly is arranged in the valve seat, the valve element assembly comprises a first valve element and a second valve element, the valve element assembly has a closed state and a throttling state, in the closed state, the first valve element and the second valve element abut against and are matched to block the other end of the first flow channel and the other end of the second flow channel, and in the throttling state, the first valve element and the second valve element abut against the valve seat. The first valve element and the second valve element are separated and matched to define a throttling channel. According to the throttling valve, the valve element assembly is arranged in the valve seat, the first valve element and the second valve element of the valve element assembly are matched to adjust the circulation section of the throttling channel, and therefore the circulation speed of refrigerants in the throttling valve can be guaranteed, and the adjustability of the throttling valve is improved.
