Embodiment Construction
[0020] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] figure 2 , image 3 Shown is a schematic structural view of the throttling device of the present invention, which includes a pipe body 1, and ports 2 and 3 are formed at both ends of the pipe body 1. In order to facilitate installation and avoid reverse installation, the ports 2 and 3 are Port 3 has a different diameter. Two fixed brackets are separately fixedly arranged inside the pipe body 1, the first bracket 4 and the second bracket 5, and a channel is opened inside the bracket, and a tapered mouth is formed at the corresponding end; The first spool 6 and the second spool 7 that the tapered mouth of the first bracket 4 and the second bracket 5 are closed, that is, the first spool 6 and the second spool 7 can respectively connec...

The invention discloses a throttling device of an air conditioner, wherein the throttling device is connected with a condenser and an evaporator through refrigerant pipes, plays a role in flow limiting and pressure reducing for refrigerants which flow in the refrigerant pipes, and comprises a pipe body, a first bracket and a first valve plug, wherein the first bracket is fixedly arranged at one inner side of the pipe body; the first bracket is provided with a through channel and one end of the through channel is provided with a conical opening; the first valve plug can seal the conical opening; and the first valve plug is axially provided with a first through channel. By utilizing the throttling device provided by the invention, the throttling pressure reduction at different flow rates under different working patterns for different air conditioners is realized through valve plugs with different calibers, and the device has a simple structure and is convenient to install; a capillary tube which is easy to go wrong is omitted; two ends of the device are provided with filtering devices; the blocking of the inner valve plug is avoided; the device is easy to dismount, thus the quality of the air conditioner is improved, and the product competitiveness is improved.
Description
technical field [0001] The invention relates to an air conditioner, in particular to a throttling device of the air conditioner. Background technique [0002] An air conditioner is a household electrical device that regulates the indoor temperature and keeps it in the condition required by the user, mainly including a refrigeration cycle system and an air cycle system. The refrigerant circulating in the refrigeration system exchanges heat with the air flowing in the room to cool down or heat up the room, and provide people with a fresh and comfortable air environment. [0003] The refrigeration circulation system of the air conditioner is composed of evaporator, condenser, compressor and throttling device, etc. The air circulation system is composed of air inlet and outlet grille, air filter device, fan and fan motor, etc. The operation of the refrigeration cycle system and air cycle system of the air conditioner is controlled by the electrical control system, such as the c...
