Wherein, two filter screens 20 and case 30 are all set up in the inner chamber of barrel 10, and two filter screens 20 set up in the both sides of case 30. The two filter screens 20 are used for ensuring the purity of the fluid in the process of flowing through the valve body, and avoiding the damage to the valve body or the abnormal operation of the valve body caused by the entry of impurities into the valve body.

The wall of the cylinder 10 is provided with two openings 11, each opening 11 is disposed between one valve core 30 and one filter screen 20, and the two openings 11 are respectively connected with two ends of the expansion valve 40 in a sealing manner. That is, with the above configuration, the expansion valve 40 and the valve body 30 are connected in parallel, and both can be switched.

The integrated valve body can realize the switching operation of the valve core 30 and the expansion valve 40. Fluid can flow in the cartridge 10 and can be filtered through the two filter screens 20. Specifically, two filter screens 20 are taken as an example of the first filter screen 20 and the second filter screen 20. When the valve body 30 is operated, the expansion valve 40 is not operated, and fluid flows in the direction of the cylinder 10, the first filter 20, the valve body 30, and the second filter 20. When the extension valve 40 is operated, the valve body 30 is not operated, and fluid flows in the directions of the cylinder 10, the second filter screen 20, the extension valve 40, and the first filter screen 20.

It should be noted that, this integrated form valve body structure is integrated form structure, and is small, and material cost is low, and the installation needs welded solder joint few, therefore simple to operate can directly install in the electrical equipment such as air conditioner, can avoid solder joint leakage scheduling problem, reduces market defective rate.

The integrated valve body structure provided by the utility model can realize the switching work of the valve core 30 and the expansion valve 40. Fluid can flow in the cartridge 10 and can be filtered through the two filter screens 20. Through with valve body structural design for integrated form structure for the volume of whole structure is less, and material cost is low, and the installation needs welded solder joint few, consequently simple to operate can direct mount to electrical equipment such as air conditioner, can avoid solder joint leakage scheduling problem, reduces market defective rate.

Furthermore, the integrated valve body structure can also reduce the occupied space of components. For example, the integrated valve body structure is used in the air conditioner, and the space of the pipeline in the air conditioner is greatly vacant, so that the space and the material use can be saved.

Further, in one embodiment provided by the present utility model, two filter screens 20 are oppositely disposed. This arrangement allows the fluid to pass through the filter screen 20 before flowing into any one of the valve bodies, regardless of the switching of the double valves, to filter out impurities therein, thereby protecting both valve bodies.

In any one of the above embodiments provided by the present utility model, the integrated valve body structure further includes: two snap rings 50, one for each filter screen 20, are provided on the inner wall of the cylinder 10 by means of one snap ring 50. The snap ring 50 can fix the filter screen 20 from two directions on one hand and can be fixed on the inner wall of the cylinder 10 on the other hand.

In any of the embodiments described above, the cylinder 10 is a straight cylinder, which facilitates the installation of the two filter screens 20 and the valve core 30, and also reduces bending in the pipe body, avoiding unnecessary resistance to the flow of fluid. Correspondingly, one end of the expansion valve 40 is connected to the opening 11 in the cylinder 10 by means of a bent pipe 41. With this structure, the other end of the expansion valve 40 is connected to the other opening 11 of the cylinder 10 through the straight pipe 42, reducing resistance in the flow of fluid from the cylinder 10 to the expansion valve 40.

Furthermore, the straight pipe 42, the bent pipe 41 and other pipe bodies in the integrated valve body structure can be copper pipes, so that the integrated valve body structure is high in stability and difficult to rust.

Further, in one embodiment provided by the present utility model, two openings 11 are welded to both ends of the extension valve 40, respectively. Through the welding process, the valve has higher strength, ensures the tightness of the joint and prolongs the service life of the integrated valve body structure.

Further, in one embodiment provided by the present utility model, the expansion valve 40 is an electronic expansion valve. When the positive and negative power voltages and signals of the coil are changed, the electronic expansion valve is opened and closed or the opening and closing gap is changed, so that the flow of the refrigerant, the refrigerating and heating values in the system are controlled. The smaller the valve core 30 is opened, the smaller the refrigerant flow amount, and the larger the cooling and heating amount thereof. Therefore, the check valve cartridge 30 may be applied to an air conditioner in combination with an electronic expansion valve.

Further, in an embodiment provided by the present utility model, the method further includes: two sections of connecting pipes 60, the two sections of connecting pipes 60 are respectively arranged at two ends of the cylinder 10, and the diameter of the connecting pipe 60 is smaller than that of the cylinder 10. The two connecting pipes 60 are used for conveying fluid, and the diameter of the cylinder 10 is larger, so that the two filter screens 20 and the valve core 30 can be conveniently installed.

The integrated valve body structure provided by the utility model can realize the switching work of the valve core 30 and the expansion valve 40. Fluid can flow in the cartridge 10 and can be filtered through the two filter screens 20. Through with valve body structural design for integrated form structure for the volume of whole structure is less, and material cost is low, and the installation needs welded solder joint few, consequently simple to operate can direct mount to electrical equipment such as air conditioner, can avoid solder joint leakage scheduling problem, reduces market defective rate.

Further, in this integrated valve body structure, two openings 11 are provided on the same side of the cylinder 10, so that the material of the pipe body can be saved, the welding points can be reduced, the bending in the pipe body can be reduced, and the connection and fixation of the expansion valve 40 can be facilitated.

Fig. 3 is a schematic diagram of an application of the integrated valve structure provided in the present utility model in an air conditioner, please refer to fig. 3. The utility model provides an air conditioner which comprises any one of the integrated valve body structures. The integrated valve body structure can be arranged in a refrigerant conveying pipeline of the air conditioner to control the refrigerant conveying process. The refrigerant transport pipe is not limited to the indoor side or the outdoor side of the air conditioner. Because the air conditioner has limited internal space, other pipelines matched with the integrated valve body structure are required to be matched with other structures to form turns and the like. In contrast, the integrated valve body structure occupies smaller space, and the space of the pipeline in the air conditioner is greatly vacant, so that the internal space and the material use can be saved.

The air conditioner provided by the utility model can realize the switching work of the valve core 30 and the expansion valve 40. Fluid can flow in the cartridge 10 and can be filtered through the two filter screens 20.
