Head external screw thread mutually twist and, so that the throttle valve 24 detachably connects towards one end of the online pipe 22 and the online pipe 22
It connects；When the air conditioner needs replacing the throttle valve 24 in maintenance process, maintenance personal can be by the cold of the air conditioner
Matchmaker is all recovered in the outdoor unit, and all shut-off valves that the outdoor unit is connected with indoor unit are closed, then directly
The throttle tube connected nut 242 and online pipe union nut 222 for being connected 24 both ends of throttle valve by spanner unclamp, and will
After the throttle valve 24 that the throttle valve 24 to be replaced more renews after removing, indoor unit is evacuated again and opens all cut-offs
Valve without paying close attention to refrigerant again, enormously simplifies the process of the air-conditioner repair, and has saved and refilled refrigerant
Cost.
In another embodiment of the present invention, one end of the throttle valve 24 towards the online pipe 22 is welded and connected with
Throttle flap connecting piece 244, the throttle flap connecting piece 244 are provided with connector internal thread, and the online pipe 22 is towards the section
One end of stream valve 24 is welded and connected with online pipe connections, and the online pipe connections are provided with connector external screw thread, the company
Fitting external screw thread can mutually be twisted with the connector internal thread and, so that the throttle valve 24 is towards one end of the online pipe 22
It is detachably connected with the online pipe 22；When the air conditioner needs replacing the throttle valve 24 in maintenance process, repair
The refrigerant of the air conditioner can be all recovered in the outdoor unit by personnel, and the institute that the outdoor unit is connected with indoor unit
There is shut-off valve closing, then directly unclamped the throttle tube connected nut 242 of described 24 one end of throttle valve by spanner, and by institute
It states throttle flap connecting piece 244 and online pipe connections unclamps, you can the throttle valve 24 to be replaced is removed, is then more renewed
The throttle valve 24, evacuate again and indoor unit and open all shut-off valves, without paying close attention to refrigerant again, enormously simplify
The process of the air-conditioner repair, and saved the cost for refilling refrigerant.
Referring to Fig. 3, throttle valve gear of the present invention further comprises 26 and second shut-off valve 27 of connecting tube, the connection
26 and second shut-off valve 27 of pipe is arranged between the throttle valve 24 and online pipe 22, and along by the throttle valve 24 to online pipe
22 directions are set gradually, second shut-off valve 27 include third channel 271 and fourth lane 272, the one of the connecting tube 26
End is connected with one end of the throttle valve 24 towards the online pipe 22, the opposite other end of the connecting tube 26 and described the
Triple channel 271 is connected, and the fourth lane 272 is connected with one end of online pipe 22 towards the throttle valve 24；The company
Take over 26 is detachably connected with throttle valve 24, and the connecting tube 26 is welded to connect with second shut-off valve 27, the four-way
Road 272 is detachably connected with online pipe 22.

Two shut-off valves 27, and the connecting tube 26 is detachably connected with throttle valve 24, and the fourth lane 272 and online pipe 22 are removable
Connection is unloaded, when the air conditioner needs replacing the throttle valve 24 in maintenance process, maintenance personal passes through according to default
After sequencing closes 23 and second shut-off valve 28 of the first shut-off valve, you can unload the throttle valve 24 to be replaced simultaneously
The new throttle valve 24 of installation can connect the outdoor unit with indoor unit, need not only refill refrigerant, Er Qiewu
The refrigerant pipe of indoor unit and online pipe 22 need to be evacuated again, it is only necessary to the throttle valve 24 be evacuated, further simplified
The process of the air-conditioner repair, and saved the cost for refilling refrigerant.
Specifically, in one embodiment of the invention, the throttle valve 24 is set towards one end of the connecting tube 26
There is a pipe fitting 243,243 outside of pipe fitting is provided with pipe fitting external screw thread, and the connecting tube 26 is towards the throttle valve 24
One end be provided with connecting tube flaring, one end of the connecting tube 26 towards the throttle valve 24 is arranged with connecting tube pipe and connects spiral shell
Mother, the connecting tube union nut can with the pipe fitting external screw thread mutually twist and, so that the throttle valve 24 and connecting tube
26 are detachably connected；When the air conditioner needs replacing the throttle valve 24 in maintenance process, if refrigerating operaton, repair
Personnel close 23 and second shut-off valve 27 (interval several seconds) of the first shut-off valve successively, if heating operation, repair people
Member closes 27 and first shut-off valve 23 (interval several seconds) of the second shut-off valve successively；Then by spanner by the throttling
The throttle tube connected nut 242 and connecting tube union nut of 24 both ends of valve connection unclamp, and by the throttle valve 24 to be replaced
The throttle valve 24 that more renews after removing need not be not only refilled cold so that the outdoor unit connects again with indoor unit
Matchmaker, and without evacuating the refrigerant pipe of indoor unit and online pipe 22 again, it is only necessary to the throttle valve 24 is evacuated, into one
The process for simplifying the air-conditioner repair is walked, and has saved the cost for refilling refrigerant.
Referring to Fig. 3, in another embodiment of the present invention, in order to avoid flaring excessively causes refrigerant in the air conditioner
Leakage, one end of the throttle valve 24 towards the connecting tube 26 are welded and connected with throttle flap connecting piece 244, and the throttle valve connects
