Problems solved by technology

[0004] At present, it is generally realized by connecting the capillary tooling outside the stop valve, but this method has the following disadvantages: (1) The capillary tooling with a nut needs to be threaded in conjunction with the stop valve joint, and the operation process is complicated
(2) Switching between different cut-off valve models requires replacement of different capillary tooling, and the versatility is not strong

Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] In the first embodiment of the present invention, a throttling tool is provided, such as figure 1 As shown, it includes a first joint 1 with a first fluid channel 11; a second joint 2 with a second fluid channel 21, wherein the first fluid channel 11 and the second fluid channel 21 also include the first fluid channel 11 and the first fluid channel 21. The fluid channel 11 is a third fluid channel that communicates with the second fluid channel 21 , and the third fluid channel is the screw channel 3 formed along the thread extension path.

[0029] The fluid enters from the inlet of the first joint 1, flows into the second joint 2 through the first fluid channel 11, and the fluid flows around the threaded ch...

Abstract

The invention discloses a throttling frock and a refrigerant recovery device with the throttling frock. The throttling frock includes a first joint with a first fluid passage and a second joint with a second fluid passage, wherein the first A third fluid channel communicated with the first fluid channel and the second fluid channel is also included between the first fluid channel and the second fluid channel, and the third fluid channel is a screw channel formed along the thread extension path. Throttle and pressure reduction are performed through the threaded channel. The structure is simple in design, strong in versatility, and easy to operate. Using the throttling tool during refrigerant recovery can improve work efficiency and ensure throttling effect.

Description

technical field [0001] The invention relates to throttling tooling, in particular to a throttling tooling used in the recovery of air-conditioning refrigerant and a refrigerant recovery device with the throttling tooling. Background technique [0002] At present, when the split type outdoor unit is repaired, when the refrigerant needs to be emptied, it is usually discharged directly to the air or through the butt pipe. For the repaired unit that has been operated, some compressor oil will be brought out more or less, especially if the number of compressors is large. It is easier for the model of the machine to carry out the compressor oil, which will reduce the amount of compressor oil in the machine for repair, affect the lubrication of the whole machine system, and affect the stability of the system. [0003] Split-type outdoor units generally use a dry evaporator. The refrigerant evaporates along the tube, and the oil is returned to the oil by the refrigerant airflow. The...
