Embodiment Construction

[0035] refer to Figure 1-Figure 8 , Figure 1-Figure 8 is a schematic diagram of one embodiment of a control valve, figure 1 , figure 2 A schematic structural view of the control valve 100 is shown. The control valve 100 includes a power head assembly 10 , a valve body 20 , a transmission rod 30 , a valve core assembly 40 , an adjustment seat assembly 50 and a cut-off member 90 . From figure 1 With the illustrated valve body structure, the control valve 100 may be an expansion valve with a cut-off component, such as a thermal expansion valve, an electronic expansion valve or other types of expansion valves.

[0036] The valve body 20 includes a first port 2011, a second port 2012, a third port 2013, a fourth port 2014, and a first valve hole 2015. Fluid can enter from the first port 2011, pass through the first valve hole 2015, and flow from the second port 2012 leaves, then enters from the third port 2013, and then leaves from the fourth port 2014; fluid can also enter...

Abstract

The invention discloses a control valve, an air conditioner system and a machining method of the control valve. The control valve comprises a valve body. The valve body comprises a first port, a second port, a third port, a fourth port, a first valve hole and a first channel. The first channel communicates with the second port. The valve body comprises a first side part, a second side part and a third side part. The first side part and the second side part are arranged oppositely. The first side part is provided with the first port and the fourth port. The second side part is provided with thesecond port and the third port. The third side part is adjacent to the first side part and adjacent to the second side part. The valve body comprises a side cavity. The opening side of the side cavity is located on the third side part. A wall part corresponding to the side cavity is at least provided with a second valve hole and a side hole. The second valve hole communicates with the first channel. The side hole communicates with the first port. The control valve can achieve the functions of forward throttling and reverse opening function and is compact in structure.

Description

technical field [0001] The invention relates to the field of refrigeration. Background technique [0002] In vehicle or household air-conditioning systems, evaporators, condensers, compressors, and throttling components are required. In general refrigeration systems, throttling components must be installed in front of the evaporator. The flow direction of the refrigerant in the throttling components is certain. . Sometimes in order to meet the needs of the system, the local refrigerant flow in the system will be switched to reverse. At this time, additional valve components need to be installed, so that there are more pipeline connections and more parts in the system. Contents of the invention [0003] The object of the present invention is to provide a control valve, an air-conditioning system and a processing method of the control valve. The control valve can realize the functions of forward throttling and reverse bypass. [0004] In order to achieve the above purpose,...
