Description

Electronic expansion valve with filtering function

Technical Field

The utility model relates to an electronic expansion valve technical field specifically is a from electronic expansion valve of taking filtering capability.

Background

When using electronic expansion valve in the current air conditioner, the valve body both ends all need add filter filtration impurity and avoid electronic expansion valve to take place the friction impaired, and this kind of mode need add two filters in addition and the welding point number also can increase two, and the cost is higher, and the installation space that the leakage risk also can increase needs simultaneously also can be great.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a from electronic expansion valve of taking filtering capability to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the electronic expansion valve with the filtering function comprises an electronic expansion valve body, wherein copper pipes are fixedly connected to the side surfaces of the lower end and the lower portion of the electronic expansion valve body, and filters are fixedly connected to the lower ends of the two copper pipes.

Preferably, the inner walls of the two copper pipes are fixedly connected with filter screens.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) this from electronic expansion valve who takes filtering capability, during the use refrigerant flows through filter flow direction copper pipe, then flows through inside the copper pipe, flows through inside the filter screen after flowing through the electronic expansion valve for need not add the filter alone when using, it is more convenient during the use, laborsaving.

(2) This from electronic expansion valve who takes filtering capability, during the use refrigerant flows through the filter flow direction copper pipe, then flows through inside the copper pipe, flows through inside the electronic expansion valve of flow direction behind the filter screen for can reduce the solder joint when using, manufacturing cost descends, and leaks the risk and reduce.

FIG. 1 is a schematic perspective view of the present invention;

fig. 2 is a schematic view of the copper pipe profile connection structure of the present invention.

In the figure: 1. an electronic expansion valve; 2. a copper pipe; 3. a filter; 4. and (4) a filter screen.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: an electronic expansion valve with a filtering function comprises an electronic expansion valve 1, wherein copper pipes 2 are fixedly connected to the lower end and the lower side surface of the electronic expansion valve 1, filters 3 are fixedly connected to the lower ends of the two copper pipes 2, filter screens 4 are fixedly connected to the inner walls of the two copper pipes 2, a refrigerant flows through the filters 3 and flows into the copper pipes 2, primary filtering is performed in the filters 3 to prevent impurities in the refrigerant from entering the copper pipes 2, the adding safety of the refrigerant is improved, the refrigerant flows through the copper pipes 2, the copper pipes 2 on the left side are L-shaped, the copper pipes 2 on the right side are bent, the refrigerant flows in a staggered manner through the difference of the shapes of the copper pipes and the copper pipes, the adding speed of the refrigerant is accelerated, the refrigerant flows into the electronic expansion valve 1 after flowing through the filter screens 4, the filter screens 4 are directly added into the copper pipes 2 at the two ends of the electronic expansion valve 1 when the electronic expansion valve is used, and the filters do not need to be added separately, the use is more convenient and labor-saving, welding spots can be reduced when the device is used, the cost is reduced, and the leakage risk is reduced.

Specifically, the utility model discloses during the use: the refrigerant flows through in the 3 flow direction copper pipes 2 of filter, carry out preliminary filtration in filter 3, prevent that the impurity in the refrigerant from getting into in the copper pipe 2, improve the interpolation security of refrigerant, then flow through inside the copper pipe 2, left copper pipe 2 is the L shape, copper pipe 2 on right side is the shape of buckling, through the difference of the two shape, let the refrigerant carry out the dislocation flow, accelerate the interpolation speed of refrigerant, flow to inside the electronic expansion valve 1 behind the filter screen 4 of flowing through, make directly add the copper pipe 2 at 1 both ends of electronic expansion valve with filter screen 4 when using, need not add the filter alone, it is more convenient during the use, and can reduce the solder joint when using, the cost descends, the leakage risk reduces.
