Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology for air replenishment, specifically an installation device for an air source heat pump jet enthalpy replenishment one-way valve. Background Technology

[0002] The vapor injection enthalpy enhancement technology in air source heat pumps is mainly used to improve heating efficiency and stability in low-temperature environments. The function of the gas injection check valve is to allow gas to flow in one direction at specific times, thereby increasing the refrigerant flow rate of the system and improving performance.

[0003] The existing one-way valve (ZY-CV-10-P) is connected to the delivery pipeline via a flange. The flange has multiple bolts installed inside the thread. When disassembling and assembling, multiple sets of bolts need to be removed, which requires the use of additional tools. In addition, the bolt parts are small and are easy to lose after disassembly, causing inconvenience during subsequent assembly. Therefore, it is necessary to improve the installation device of the air source heat pump jet enthalpy injection one-way valve to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an installation device for a one-way valve for injecting enthalpy-enhancing gas in an air source heat pump, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air source heat pump jet enthalpy boosting and gas replenishment one-way valve installation device, comprising a one-way valve body and two gas supply pipes, two limiting blocks fixedly installed on the outside of the one-way valve body, four mounting blocks I fixedly installed on the outside of the one-way valve body, two mounting blocks II fixedly installed on the outside of each of the two gas supply pipes, a hanging block fixedly installed on the outside of the mounting blocks II, a fixing frame fixedly installed on the outside of the mounting blocks I, a pressing block movably installed on the outside of the fixing frame, and a hanging ring rotatably installed inside the pressing block.

[0006] Preferably, the one-way valve body is concentric with the gas supply pipe, and the one-way valve body is disposed between the two gas supply pipes. The hanging ring is snapped onto the outside of the hanging block, and the hanging block and the fixing frame are both installed by bolts.

[0007] Preferably, the two limiting blocks are respectively attached to the outside of the two gas pipes, and a protrusion is fixedly installed on the outside of the first mounting block, and the protrusion abuts against the outside of the second mounting block.

[0008] Preferably, four springs are fixedly installed inside the one-way valve body, and a plug ring is fixedly installed at the end of the spring away from the one-way valve body. A sealing ring is fixedly installed inside both of the gas pipes, and two limiting posts are fixedly installed on the side of the plug ring near the spring.

[0009] Preferably, the limiting post is slidably installed inside the one-way valve body, and there are two plug rings, both of which are slidably installed inside the one-way valve body.

[0010] Preferably, the two insertion rings are respectively inserted into the inside of the two gas supply pipes, and the insertion rings abut against the sealing rings.

[0011] Preferably, a pull rope is fixedly installed on the inner side of each of the two plug rings, and a pull block is fixedly installed at the end of the pull rope away from the plug ring. The pull block is slidably installed inside the one-way valve body, and a maintenance door is provided inside the one-way valve body.

[0012] Compared with the prior art, this utility model provides an installation device for a one-way valve for injecting enthalpy-enhancing gas in an air source heat pump, which has the following advantages:

[0013] 1. The air source heat pump jet enthalpy boosting gas replenishment one-way valve installation device uses a pull block to pull the pull rope, which drives the plug ring to retract into the one-way valve body. This allows the one-way valve body to be lifted and moved between two gas supply pipes. Under the action of two limit blocks, the positioning process is completed. When the protrusion of the first installation block abuts against the second installation block, the position of the hanging ring and the hanging block is aligned, facilitating subsequent operations.

[0014] 2. Based on this, the present invention integrates the one-way valve body into a module, which supports quick plug-in and plug-out installation. When maintaining the one-way valve body, the four sets of hanging rings and their connected components are removed, and then the pull block is pulled up to retract the two plug-in rings into the one-way valve body, thus completing the disassembly operation of the one-way valve body without disassembling other components.

[0015] 3. Based on this, the present invention uses bolts to install the hanging block and the fixing frame, so that when the two are worn and damaged after long-term use, they can be replaced separately. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example 1:

[0025] Please see Figure 1-4 This utility model provides a technical solution: an air source heat pump jet enthalpy boosting and gas replenishment one-way valve installation device, including a one-way valve body 1 and two gas supply pipes 2. Two limiting blocks 3 are fixedly installed on the outside of the one-way valve body 1. Four mounting blocks 4 are fixedly installed on the outside of the one-way valve body 1. Two mounting blocks 5 are fixedly installed on the outside of each of the two gas supply pipes 2. Hanging blocks 6 are fixedly installed on the outside of the mounting blocks 5. Fixing frames 7 are fixedly installed on the outside of the mounting blocks 4. Pressing blocks 8 are movably installed on the outside of the fixing frames 7. A hanging ring 9 is rotatably installed inside the pressing blocks 8.

[0026] Furthermore, the one-way valve body 1 is concentric with the gas supply pipe 2, and the one-way valve body 1 is located between the two gas supply pipes 2. The hanging ring 9 is snapped onto the outside of the hanging block 6. The hanging block 6 and the fixing frame 7 are both installed by bolts, and the hanging block 6 and the fixing frame 7 can be replaced individually.

[0027] Furthermore, the two limiting blocks 3 are respectively attached to the outside of the two gas pipes 2, and the outside of the mounting block 1 4 is fixedly installed with a protrusion, and the protrusion abuts against the outside of the mounting block 2 5, so that the hanging block 6 corresponds to the position of the fixing frame 7.

[0028] Example 2:

[0029] Please see Figure 3-4 Furthermore, in conjunction with Embodiment 1, it is further found that four springs 10 are fixedly installed inside the one-way valve body 1, and a plug ring 11 is fixedly installed at the end of the spring 10 away from the one-way valve body 1. A sealing ring 12 is fixedly installed inside the two gas pipes 2. Two limiting posts 13 are fixedly installed on the side of the plug ring 11 close to the spring 10, so that the movement of the plug ring 11 is more stable.

[0030] Furthermore, the limiting post 13 is slidably installed inside the one-way valve body 1, and there are two plug rings 11, both of which are slidably installed inside the one-way valve body 1, which facilitates the installation of the one-way valve body 1.

[0031] Furthermore, the two insertion rings 11 are respectively inserted into the inside of the two gas supply pipes 2, and the insertion rings 11 abut against the sealing rings 12, so that the sealing effect between the one-way valve body 1 and the gas supply pipe 2 is better.

[0032] Furthermore, pull ropes 14 are fixedly installed on the inner side of both plug rings 11. A pull block 15 is fixedly installed at the end of the pull rope 14 away from the plug ring 11. The pull block 15 is slidably installed inside the one-way valve body 1. A maintenance door 16 is provided inside the one-way valve body 1. The two pull ropes 14 pull the two plug rings 11 to move.

[0033] In actual operation, when this device is used, lift the one-way valve body 1, pull the pull block 15 upwards so that the two pull ropes 14 pull the two plug rings 11, compressing the spring 10. The spring 10 is initially in a stretched state, causing the two plug rings 11 to retract into the one-way valve body 1. Then, push the one-way valve body 1 backwards with the two limit blocks 3 facing you, and then release the pull block 15. At this time, the plug rings 11 abut against the side of the gas pipe 2 near the one-way valve body 1. Then, continue to push the one-way valve body 1 backwards until the two limit blocks 3 are attached to the outside of the two gas pipes 2. At this time, the one-way valve body 1 is inserted between the two gas pipes 2 and is concentric with the two gas pipes 2. Then, rotate the one-way valve body 1 so that the convex part on the outside of the mounting block 1 4... The first mounting block 4 is brought close to the second mounting block 5 until they are flush, so that the top of the first mounting block 4 and the second mounting block 5 are level. Then, the pressing block 8 is lifted to hang the hanging ring 9 on the outside of the hanging block 6. Then, the pressing block 8 is pressed down to make the hanging ring 9 hang tightly on the outside of the hanging block 6. The other three are done in the same way, so that the one-way valve body 1 and the air supply pipe 2 are installed. At the same time, the plug ring 11 corresponds to the plug groove. The spring 10 rebounds and drives the plug ring 11 to reset, so that the plug ring 11 is inserted into the inside of the air supply pipe 2. The plug ring 11 is pressed tightly against the outside of the sealing ring 12, so that the one-way valve body 1 and the air supply pipe 2 have a better sealing effect. After the two plug rings 11 are inserted into the inside of the air supply pipe 2, the pressure of the gravity of the one-way valve body 1 on the four sets of hanging rings 9 and their connected components is reduced, thus extending their service life.

[0034] Furthermore, the one-way valve body 1 is integrated into a module with standardized dimensions, supporting quick plug-and-play installation. When maintaining the one-way valve body 1, the four sets of hanging rings 9 and their connected components are removed, and then the pull block 15 is pulled up to retract the two plug rings 11 into the one-way valve body 1, thus completing the disassembly operation of the one-way valve body 1 without disassembling other components. When maintenance of the one-way valve body 1 is required, it can be disassembled and placed on the desktop for careful maintenance.

[0035] Furthermore, a bolted inspection door 16 is added to the outer shell of the one-way valve body 1 to facilitate maintenance of the components deep inside the one-way valve body 1.

[0036] Furthermore, the hanging block 6 and the fixing bracket 7 are all installed by bolts. When the parts are worn and damaged after long-term use, the hanging block 6 and the fixing bracket 7 can be replaced separately.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
