Description

Technical Field

[0001] This utility model relates to the field of air conditioning liquid receiver technology, and in particular to an air conditioning liquid receiver with pressure regulation function. Background Technology

[0002] The air conditioning receiver is an important component of the air conditioning system. During the operation of the air conditioning system, the receiver can store a certain amount of refrigerant to ensure that there is enough refrigerant circulating under different operating conditions. When the system load changes, the receiver can stabilize the refrigerant flow. It can separate the gaseous and liquid parts of the refrigerant coming out of the condenser to ensure that only the liquid refrigerant enters the evaporator, thereby improving the heat exchange efficiency of the evaporator.

[0003] A pressure-adjustable air conditioning liquid receiver is disclosed in utility model application number 202021451408.8. By setting an elastic sealing block, when the user uses it, the user first inserts the connecting pipe into the inner side of the sealing block and connects it to the connecting pipe. After connection, the user can connect the ring. At this time, the connecting ring rotates outward under the action of the adjusting ring. The connecting ring drives the connecting block to rotate under the action of the adjusting ring. The connecting ring slides inside the connecting block. When the connecting ring rotates to the elastic sealing block, the elastic sealing block is squeezed by the connecting ring under the action of the limiting bracket. Under the action of the squeezing force, the elastic sealing block deforms and compresses the telescopic rod and the adjusting spring. Under the action of the adjusting spring, the elastic sealing block is pressed tightly against the outside of the connecting pipe to complete the sealing process. During this process, the connecting block can limit the connecting ring, making it more convenient for the user to use. Thus, the device has the advantage of conveniently sealing the connection point, making it convenient for the user.

[0004] However, the aforementioned pressure-adjustable air conditioning receiver can only stabilize the air conditioning system pressure to a certain extent and cannot adjust the pressure independently as needed. This means that when the load on the air conditioning system suddenly increases, the refrigerant in the receiver must wait for the internal pressure to rise before it can be released to the evaporator. In the aforementioned pressure-adjustable air conditioning receiver, the elastic sealing block is pressed tightly against the outside of the connecting pipe under the action of extrusion force for sealing. This can only clamp and seal the connecting pipe from top to bottom, which can easily affect the sealing effect. Therefore, this utility model proposes an air conditioning receiver with pressure regulation function to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to propose an air conditioning receiver with pressure regulation function. This air conditioning receiver with pressure regulation function injects refrigerant into the receiver body by opening the solenoid valve and extending the electric telescopic rod to push the pressure plate, thereby regulating and increasing the internal pressure and accelerating the release of refrigerant to the evaporator through the second connecting pipe. This solves the problem of waiting for the internal air pressure of the receiver body to rise when the load of the air conditioning system suddenly increases. After inserting the sealing tube through the pipe, tightening the threaded fastening sleeve along the external threaded pipe compresses the sealing tube, making the sealing ring tightly fit the pipe to achieve a full-range seal.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: an air conditioning liquid receiver with pressure regulation function, including a liquid receiver body, a controller, an automatic pressure regulation mechanism, a communication mechanism, and a connecting sealing mechanism. The controller is fixedly installed on the upper side of one side of the liquid receiver body. The automatic pressure regulation mechanism includes an auxiliary liquid receiver tank, an electric telescopic rod, a pressure rod, a pressure plate, a constant pressure pipe, a connecting pipe, and a solenoid valve. An auxiliary liquid receiver tank is fixedly installed on one side of the liquid receiver body. An electric telescopic rod is fixedly installed on the top of the auxiliary liquid receiver tank. The telescopic end of the electric telescopic rod extends into the auxiliary liquid receiver tank and a pressure rod is fixedly installed therein. A pressure plate is fixedly installed at the lower end of the pressure rod. A constant pressure pipe is connected to the upper side of one side of the auxiliary liquid receiver tank. A connecting pipe is connected to the liquid receiver body on the lower side of the other side of the auxiliary liquid receiver tank. A solenoid valve is fixedly installed on the constant pressure pipe and the connecting pipe. A communication mechanism is provided inside the liquid receiver body. A connecting sealing mechanism is provided on the top of the liquid receiver body.

[0007] Further improvements include: the controller is electrically connected to the electric telescopic rod and the solenoid valve; the pressure plate is in contact with the inner wall of the auxiliary storage tank; and one end of the constant pressure pipe is located above the pressure plate.

[0008] A further improvement is that the other end of the constant pressure tube opens downwards, and the other end of the connecting tube extends into the main body of the liquid reservoir with its opening facing downwards and close to the lower part of the inner wall of the main body of the liquid reservoir.

[0009] A further improvement is that the connecting mechanism includes a first connecting pipe, a second connecting pipe, a sight glass, and a filter screen. The first connecting pipe is inserted into the upper part of one side of the liquid reservoir body, and the second connecting pipe is inserted into the upper part of the other side of the liquid reservoir body. The sight glass is fixedly connected to the middle of the top of the liquid reservoir body. The filter screen is fixedly installed inside the lower end of the second connecting pipe. The upper ends of the first connecting pipe and the second connecting pipe are provided with a connecting sealing mechanism.

[0010] A further improvement is that the lower end of the first connecting pipe is located in the middle section of the liquid reservoir body, and the lower end of the second connecting pipe is located at the bottom of the liquid reservoir body.

[0011] A further improvement is that the connecting sealing mechanism includes a limiting ring, an external threaded pipe, a threaded fastening sleeve, a sealing pipe, and a sealing ring. The upper ends of the first and second connecting pipes are fitted with a limiting ring, and the limiting ring is fitted with an external threaded pipe. The external threaded pipe is screwed into the threaded fastening sleeve, and the first and second connecting pipes are fitted with a sealing pipe. The sealing pipe is fitted with a sealing ring inside.

[0012] A further improvement is that a fixing ring is fixedly provided on the lower part of the liquid reservoir body, a support leg is fixedly provided around the fixing ring, and a pressure gauge is fixedly provided on the upper part of the other side of the liquid reservoir body.

[0013] The beneficial effects of this utility model are as follows: After the solenoid valve is opened, the electric telescopic rod extends and pushes the pressure plate to inject refrigerant into the main body of the receiver, thereby adjusting and increasing the internal pressure and accelerating the release of refrigerant to the evaporator through the second connecting pipe. This solves the problem of waiting for the internal air pressure of the receiver to rise when the load of the air conditioning system suddenly increases. After inserting the sealing pipe through the pipeline, the threaded fastening sleeve is tightened along the external threaded pipe to compress the sealing pipe, so that the sealing ring fits tightly against the pipeline to achieve all-round sealing.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides an air conditioning liquid receiver with pressure regulation function, including a liquid receiver body 1, a controller 2, an automatic pressure regulating mechanism, a connecting mechanism, and a connecting sealing mechanism. The controller 2 is fixedly mounted on the upper side of one side of the liquid receiver body 1. The automatic pressure regulating mechanism includes an auxiliary liquid receiver tank 3, an electric telescopic rod 4, a pressure rod 5, a pressure plate 6, a constant pressure pipe 7, a connecting pipe 8, and a solenoid valve 9. The auxiliary liquid receiver tank 3 is fixedly mounted on one side of the liquid receiver body 1. An electric telescopic rod 4 is fixedly mounted on the top of the auxiliary liquid receiver tank 3. The telescopic end of the electric telescopic rod 4 extends into the auxiliary liquid receiver tank 3 and a pressure rod 5 is fixedly mounted thereon. A pressure plate 6 is fixedly mounted on the lower end of the pressure rod 5. A constant pressure pipe 7 is connected to the upper side of one side of the auxiliary liquid receiver tank 3. A connecting pipe 8 is connected to the liquid receiver body 1 on the lower side of the other side of the auxiliary liquid receiver tank 3. A solenoid valve 9 is fixedly mounted on the constant pressure pipe 7 and the connecting pipe 8. The controller 2 is electrically connected to the electric telescopic rod 4 and the solenoid valve 9. The pressure plate 6 is fitted to the inner wall of the auxiliary liquid receiver 3. One end of the constant pressure pipe 7 is located above the pressure plate 6. The main body 1 of the liquid receiver is equipped with a connecting mechanism, and the top of the main body 1 of the liquid receiver is equipped with a connecting sealing mechanism. When the load of the air conditioning system suddenly increases, the controller 2 controls the solenoid valve 9 to open. At the same time, the electric telescopic rod 4 starts to extend and push the pressure rod 5 and the pressure plate 6 to descend, injecting the refrigerant stored in the auxiliary liquid receiver 3 into the main body 1 of the liquid receiver, accelerating the rise of the internal pressure of the main body 1 of the liquid receiver, so that the refrigerant can be released to the evaporator more quickly. When the load of the air conditioning system decreases, the electric telescopic rod 4 retracts and drives the pressure rod 5 and the pressure plate 6 to rise, forming a negative pressure to draw the refrigerant into the auxiliary liquid receiver 3, and then closes the solenoid valve 9 to assist in storing the refrigerant, accelerating the drop of the pressure of the main body 1 of the liquid receiver. This solves the problem that when the load of the air conditioning system increases, it is necessary to wait for the internal pressure of the main body 1 of the liquid receiver to rise before the refrigerant can be released, thus accelerating the release speed of the refrigerant.

[0020] The other end of the constant pressure pipe 7 is open downwards, and the other end of the connecting pipe 8 extends into the liquid receiver body 1 with its opening facing downwards and close to the lower part of the inner wall of the liquid receiver body 1. The constant pressure pipe 7 is connected to the outside to stabilize the gas pressure in the auxiliary liquid receiver 3, and the connecting pipe 8 is inserted into the refrigerant to facilitate quick extraction of refrigerant.

[0021] The connecting mechanism includes a first connecting pipe 10, a second connecting pipe 11, a sight glass 12, and a filter screen 13. The first connecting pipe 10 is inserted into the upper part of one side of the liquid receiver body 1, and the second connecting pipe 11 is inserted into the upper part of the other side of the liquid receiver body 1. The sight glass 12 is fixedly connected to the middle of the top of the liquid receiver body 1. The filter screen 13 is fixedly installed inside the lower end of the second connecting pipe 11. The lower end of the first connecting pipe 10 is located in the middle section of the liquid receiver body 1, and the lower end of the second connecting pipe 11 is located at the bottom of the liquid receiver body 1. The upper ends of the first connecting pipe 10 and the second connecting pipe 11 are provided with a connecting sealing mechanism. When the refrigerant enters the liquid receiver body 1 through the first connecting pipe 10, the gaseous refrigerant floats above the liquid receiver body 1, and the liquid refrigerant gathers at the bottom of the liquid receiver body 1. When the pressure rises, the liquid refrigerant is released through the second connecting pipe 11 to the evaporator for cooling and to improve the heat exchange efficiency of the evaporator.

[0022] The sealing mechanism includes a limiting ring 14, an external threaded pipe 15, a threaded fastening sleeve 16, a sealing pipe 17, and a sealing ring 18. The limiting ring 14 is fixedly installed on the upper end of the first connecting pipe 10 and the second connecting pipe 11. The external threaded pipe 15 is fixedly installed on the limiting ring 14. The threaded fastening sleeve 16 is screwed into the external thread of the external threaded pipe 15. The sealing pipe 17 is fixedly installed on the first connecting pipe 10 and the second connecting pipe 11. The sealing ring 18 is inserted into the inner side of the sealing pipe 17. When installing and connecting the air conditioning system, the pipes are inserted into the first connecting pipe 10 and the second connecting pipe 11 respectively. Then, the threaded fastening sleeve 16 is tightened by rotating along the external threaded pipe 15, which compresses the sealing pipe 17 so that the sealing pipe 17 and the sealing ring 18 fit tightly with the pipe to achieve a full-range sealing effect.

[0023] A fixing ring 19 is fixedly provided on the lower part of the liquid reservoir body 1, and a support leg 20 is fixedly provided around the outside of the fixing ring 19. A pressure gauge 21 is fixedly provided on the upper part of the other side of the liquid reservoir body 1 to facilitate direct observation of the pressure changes inside the liquid reservoir body 1.

[0024] This is an air conditioning liquid receiver with pressure regulation function.
