Description

Technical Field

[0001] This utility model relates to the field of compressor equipment technology, and in particular to a limiting component for a compressor. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the core equipment in a refrigeration system. During the operation of a compressor, the reciprocating motion of the piston needs to be controlled to regulate the pressure changes inside the cylinder. During this period, the valve plate in the exhaust valve controls the closing of the exhaust. The limiting component used in a compressor generally refers to a device that limits the valve plate.

[0003] Patent publication number CN219062479U discloses an exhaust valve structure for a compressor, comprising: a stationary scroll plate, an exhaust valve plate, and a limiting block. The limiting block is detachably connected to one side of the stationary scroll plate, and its front side has an upwardly curved bend. The exhaust valve plate is pressed between the limiting block and the stationary scroll plate. A buffer layer is provided at the front end of the exhaust valve plate. The bottom of the buffer layer contacts and seals with the exhaust port of the stationary scroll plate, and the top of the buffer layer makes movable contact with the bend on the limiting block. Compared with existing exhaust valve plates, this structure allows for faster opening during exhaust, more timely valve plate reset and closure, better sealing of the compression chamber, and improved frequency response performance of the entire exhaust valve plate, resulting in a smoother frequency response curve. In particular, it reduces vibration and noise when the exhaust valve plate collides with the limiting block and the stationary scroll plate, extending the service life of the exhaust valve plate and further improving the performance and lifespan of the compressor.

[0004] When the exhaust valve is working, the valve plate will swing with the change of air pressure. The limit block set in the above device limits the valve plate and realizes the function of reducing noise. Since the limit block and the valve plate are fixed by bolts and pressed together, the limit block will apply a large pressure to the valve plate after pressing. If the valve plate is worn or the pressed part is deformed or even broken after repeated installation and disassembly, it will affect its service life. Therefore, a limit component for compressor is proposed to solve the above problems. Utility Model Content

[0008] The first limiting block is provided with an installation mechanism, and an installation groove is provided at the bottom of the first limiting block;

[0009] The mounting mechanism includes a pad, and both the pad and the valve plate are placed inside the mounting groove and match the mounting groove.

[0010] The gasket is placed on top of the valve plate and contacts the valve plate;

[0012] The first limiting block has a first through groove, the pad has a second through groove, and the valve plate has a third through groove. The first limiting plate is placed inside the first through groove, and the second limiting plate is placed inside the third through groove. An intermediate rod is fixedly connected between the first limiting plate and the second limiting plate, and the intermediate rod passes through the second through groove.

[0013] By adopting the above technical solution, the first limiting block and the second limiting block are assembled to form a complete limiting plate. Before the valve plate is installed, the gasket is first inserted and installed from one side of the first limiting block. Finally, the valve plate is placed into the installation groove from below the first limiting block. This assembly and splicing ensures that the bottom of the valve plate is on the same plane as the bottom of the first limiting block. This prevents the limiting block from directly resting on the valve plate and applying full pressure to the valve plate during overall installation, which could potentially damage the valve plate. This effectively protects the valve plate.

[0014] Preferably, the first limiting block has a slot that is connected to the first through slot, and a locking block is slidably connected inside the first limiting plate, extending into the slot and matching the slot.

[0015] By adopting the above technical solution, after the card block extends into the card slot, the first limiting plate cannot be moved.

[0019] By adopting the above technical solution, there is friction between the second limiting plate and the bottom of the pad.

[0020] Preferably, the first limiting block has a placement groove that is connected to the slot. A placement block is placed inside the placement groove and matches the placement groove. The placement block passes through the insert plate. An auxiliary groove is provided on the top of the first limiting block. A positioning groove is provided inside the first limiting block and is located between the placement groove and the auxiliary groove. The positioning groove is connected to both the placement groove and the auxiliary groove. A trapezoidal positioning block is slidably connected inside the placement block. A control plate is slidably connected inside the auxiliary groove. A push block is fixedly connected to one side of the control plate. Both the push block and the trapezoidal positioning block extend into the positioning groove and match the positioning groove.

[0021] By adopting the above technical solution, the trapezoidal positioning block extends into the positioning groove and limits the placement of the block.

[0022] Preferably, a second spring is fixedly connected inside the auxiliary groove, a third spring is fixedly connected inside the placement block, the second spring is fixedly connected to the control board, the third spring is fixedly connected to the trapezoidal positioning block, a top plate is slidably connected inside the placement groove, the top plate is set at the bottom of the placement block and fits against the placement block, a fourth spring is fixedly connected to the bottom of the top plate, and the fourth spring is fixedly connected inside the placement groove.

[0023] By adopting the above technical solution, the fourth reed exerts an elastic force on the top plate.

[0024] Preferably, the valve plate has an installation hole and a positioning hole. The bottom of the first limiting block is fixedly connected to a ring plate and a positioning rod. The ring plate passes through the installation hole and matches the installation hole. The positioning rod passes through the positioning hole and matches the positioning hole. It also passes through the second installation hole and matches the second installation hole.

Before installing the valve plate, a gasket is first inserted and installed from one side of the first limiting block, and finally the valve plate is placed into the mounting groove from below the first limiting block for assembly. The bottom of the valve plate is on the same plane as the bottom of the first limiting block. This ensures that during overall installation, the limiting block does not directly remain above the valve plate and apply full pressure to the valve plate, which could potentially damage the valve plate. This effectively protects the valve plate.

[0028] 2. A limiting component for a compressor, which allows for flexible disassembly and assembly of a first limiting block and a second limiting block, thereby enabling quick replacement of the second limiting block with different inclined surfaces to change the limiting angle of the valve plate and achieve multi-angle limiting.

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 The present invention will be described in further detail below.

[0039] This utility model discloses a limiting component for a compressor. (Refer to...) Figures 1-8 The first limiting block 1, the second limiting block 2, and the valve plate 3 are provided. The first limiting block 1 is provided with an installation mechanism 4, which includes a pad 41. The bottom of the first limiting block 1 is provided with an installation groove 42. The pad 41 and the valve plate 3 are both placed inside the installation groove 42 and matched with the installation groove 42. The pad 41 is provided on the top of the valve plate 3 and contacts the valve plate 3. The first limiting block 1 is provided with a slot 43 on one side. The second limiting block 2 is integrally formed with an insert plate 44 on one side. The insert plate 44 extends into the slot 43 and matches with the slot 43. The first limiting block 1 and the second limiting block 2 are in close contact.

[0040] The first limiting block 1 has a first through groove 45, the pad 41 has a second through groove 46, and the valve plate 3 has a third through groove 47. The first limiting plate 48 is placed inside the first through groove 45, and the second limiting plate 49 is placed inside the third through groove 47. An intermediate rod 491 is fixedly connected between the first limiting plate 48 and the second limiting plate 49, and the intermediate rod 491 passes through the second through groove 46. After the first limiting block 1 and the second limiting block 2 are assembled, they form a complete limiting plate component. Before installing the valve plate 3, the pad is first inserted from one side of the first limiting block 1, and then the valve plate 3 is placed into the installation groove 42 from below the first limiting block 1. This assembly and splicing ensures that the bottom of the valve plate 3 is on the same plane as the bottom of the first limiting block 1. This prevents the limiting block from directly resting above the valve plate 3 and applying full pressure to the valve plate 3, which could potentially damage the valve plate 3 during overall installation, thus effectively protecting the valve plate 3.

[0041] The first limiting block 1 has a slot 492, which is connected to the first through slot 45. A locking block 493 is slidably connected inside the first limiting plate 48. The locking block 493 extends into the slot 492 and matches the slot 492. After the locking block 493 extends into the slot 492, the first limiting plate 48 cannot move. A first spring 494 is fixedly connected inside the first limiting plate 48. The first spring 494 is fixedly connected to one side of the locking block 493. The first spring 494 exerts an elastic force on the locking block 493. The first limiting plate 48 is in contact with the inner wall of the first through slot 45. The second limiting plate 49 is in contact with the bottom of the pad 41. There is friction between the second limiting plate 49 and the bottom of the pad 41.

[0042] The first limiting block 1 has a placement groove 495, which is connected to the slot 43. A placement block 496 is placed inside the placement groove 495, and the placement block 496 matches the placement groove 495. The placement block 496 passes through the insert plate 44. An auxiliary groove 497 is provided on the top of the first limiting block 1. A positioning groove 498 is provided inside the first limiting block 1, which is located between the placement groove 495 and the auxiliary groove 497. The positioning groove 498 is respectively connected to the placement groove 495 and the auxiliary groove 497. The auxiliary groove 497 is connected, and a trapezoidal positioning block 499 is slidably connected inside the placement block 496. A control plate 481 is slidably connected inside the auxiliary groove 497. A push block 482 is fixedly connected to one side of the control plate 481. Both the push block 482 and the trapezoidal positioning block 499 extend into the positioning groove 498. Both the push block 482 and the trapezoidal positioning block 499 match the positioning groove 498. After the trapezoidal positioning block 499 extends into the positioning groove 498, it limits the placement block 496.

[0043] A second spring 483 is fixedly connected inside the auxiliary slot 497, and a third spring 484 is fixedly connected inside the placement block 496. The second spring 483 is fixedly connected to the control board 481, and the third spring 484 is fixedly connected to the trapezoidal positioning block 499. A top plate 485 is slidably connected inside the placement slot 495. The top plate 485 is located at the bottom of the placement block 496 and fits against the placement block 496. A fourth spring 486 is fixedly connected to the bottom of the top plate 485 and is fixedly connected inside the placement slot 495. The four springs 486 exert an elastic force on the top plate 485. The valve plate 3 has a mounting hole 487 and a positioning hole 488. The bottom of the first limiting block 1 is fixedly connected to a ring plate 489 and a positioning rod 471. The ring plate 489 passes through the mounting hole 487 and matches the mounting hole 487. The positioning rod 471 passes through the positioning hole 488 and matches the positioning hole 488. It also passes through the second mounting hole 487 and matches the second mounting hole 487. The compressor is installed through the first mounting hole 487 and the second mounting hole 487.

[0044] In actual operation, when assembling the first limiting block 1 and the second limiting block 2, after inserting the insert plate 44 on one side of the second limiting block 2 into the slot 43, the placement block 496 is placed into the placement groove 495. During the placement of the placement block 496, the inclined surface on the trapezoidal positioning block 499 is squeezed, causing the trapezoidal positioning block 499 to move into the placement block 496. When the placement block 496 is completely placed into the placement groove 495, the trapezoidal positioning block 499 is on one side of the positioning groove 498. At this time, the third spring 484 pushes the trapezoidal positioning block 499 into the positioning groove 498. The placement block 496 remains in the state of penetrating the insert plate 44, thereby completing the splicing and installation of the first limiting block 1 and the second limiting block 2. When the placement block 496 is inserted, the placement block 496 presses the top plate 485 downward, causing the top plate 485 to press the fourth spring 486. At this time, the fourth spring maintains an elastic force on the top plate 485. After the first limiting block 1 and the second limiting block 2 are spliced ​​together, a complete limiting plate is formed. When the valve plate 3 swings under the action of airflow, it will touch the bottom inclined surface of the second limiting block 2, thereby achieving the purpose of limiting the swing angle of the second limiting block 2.

[0045] If it is necessary to remove the first limiting block 1 and the second limiting block 2, the control plate 481 is pushed. The control plate 481 drives the pushing block 482 to move to touch the trapezoidal positioning block 499 and push the trapezoidal positioning block 499 into the placement block 496. At the same time, due to the elastic force of the fourth spring 486 on the top plate 485, the top plate 485 quickly pushes the placement block 496 upward, so that the top of the placement block 496 is higher than the placement groove 495. After the user takes it out, the first limiting block 1 and the second limiting block 2 can be separated. The bottom of the second limiting block 2 is an inclined surface. Through the above operation, the second limiting block 2 with different inclination angles can be flexibly replaced to change the limiting angle of the valve plate 3 and achieve the purpose of multi-angle limiting. Compared with the traditional integrated limiting structure, it is more flexible to use.

[0046] When installing the valve plate 3, first insert the pad 41 into the opening on one side of the mounting groove 42. Then, place the second limiting plate 49 downwards. After the second limiting plate 49 passes through the bottom of the pad 41, rotate the first limiting plate 48 to make the locking block 493 inside the first limiting plate 48 position in the corresponding position of the locking groove 492. Then, the first spring 494 pushes the locking block 493 into the locking groove 492. At this time, the first limiting plate 48 and the second limiting plate 49 remain stable, thereby limiting the pad 41 and ensuring the stability of the pad 41 after installation. Finally, place the valve plate 3 into the mounting groove 42 from the bottom of the first limiting block 1. During the placement process, the ring plate 489 and the positioning rod 471 pass through the mounting hole 487 and the positioning rod 471, respectively. After passing through hole 488, valve plate 3 can be placed directly downwards on the stationary plate (not shown in the diagram) and bolts can be screwed in. After the bolts pass through ring plate 489, valve plate 3 is pressed onto the stationary plate. Compared with the traditional method of directly pressing valve plate 3 through bolts, the ring plate 489 blocks the bolts, preventing the threads from damaging the contact parts of valve plate 3 during the screwing process. After pressing, the bottom of valve plate 3 is on the same plane as the bottom of the first limiting block 1, thus avoiding the situation where valve plate 3 is easily broken due to excessive pressure simply because it is at the bottom. In addition, the pad 41 contacts the top of valve plate 3, which can further protect valve plate 3 and effectively extend the service life of valve plate 3.

[0047] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
