Description

Technical Field

[0001] This utility model relates to the field of exhaust valve plate technology, specifically to a compressor exhaust valve plate assembly. Background Technology

[0002] A compressor is a fluid machine that raises low-pressure gas to high-pressure gas, and it is a core piece of equipment in refrigeration systems, aerodynamic systems, and other fields. The exhaust valve, as a key component of the compressor's valves, functions to open promptly during piston compression to discharge high-pressure gas, and to close quickly after discharge to prevent gas backflow. Its performance directly affects the compressor's efficiency and reliability.

[0003] In the existing technology, the compressor exhaust valve plate assembly is usually directly fixed to the compressor body by bolts. Because the valve plate is subjected to alternating stress and impact for a long time in high-speed and high-frequency reciprocating motion, it is prone to fatigue damage. Therefore, it is a vulnerable part that needs to be replaced regularly. This direct fixing connection method means that when replacing the valve plate, the bolts connecting the compressor body and the valve plate assembly must be repeatedly disassembled and installed.

[0004] Over time, frequent disassembly and assembly operations can easily lead to wear, stripping, or even damage to the threaded holes on the compressor body. Since the manufacturing cost and value of the compressor body are far higher than that of the valve plate assembly itself, once such damage occurs on the body, the cost of repair or replacement is high and the process is complicated, which brings inconvenience and economic burden to the long-term maintenance of the equipment.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3 As shown, this utility model provides a technical solution:

[0024] A compressor exhaust valve assembly includes a mounting base 1 with a mounting groove 2 extending through its top center. Fixing blocks 7 are fixedly connected to both ends of the mounting base 1, and bolt holes 8 extend through the center of each fixing block 7. A mounting plate 3 is detachably connected to the mounting groove 2. Fixing blocks 18 are fixedly connected to both ends of the mounting plate 3, and locking screws 5 are threadedly connected to the center of each fixing block 18. Locking holes 6, threaded to the locking screws 5, are provided on both sides of the top of the mounting base 1. A valve body 4 is positioned directly below the bottom of the mounting plate 3. A lifting mechanism is provided between the valve body 4 and the mounting plate 3. The lifting mechanism includes a lifting block 9 fixedly connected to the top left side of the valve body 4, and a lifting block 9 fixedly connected to the upper right side of the lifting block 9 at an angle to the valve body 4. The mounting plate 3 has a parallel limiting inclined plate 10. The left side of the mounting plate 3 is threaded with an adjusting screw 11. The bottom end of the adjusting screw 11 is rotatably connected to the top left side of the lifting block 9 through a bearing. The top right side of the lifting block 9 is fixedly connected with a vertical guide rod 12. The left side of the mounting plate 3 has a through hole 13 that is slidably connected to the guide rod 12. The positioning mechanism is located between the two sides of the mounting plate 3 and the fixed seat 1. The positioning mechanism includes positioning inclined blocks 14 that are symmetrically fixedly connected to the outer sides of the two ends of the middle part of the mounting plate 3, and positioning holes 15 that are symmetrically opened at the top of the two sides of the middle part of the fixed seat 1. The bottom middle of the positioning inclined block 14 is fixedly connected with a positioning rod 16 that matches the positioning hole 15. The bottom two sides of the fixed seat 1 are provided with ventilation grooves 17 that communicate with the mounting groove 2.

[0025] In this embodiment, by setting a detachable mounting plate 3 and a fixing seat 1, and by using a locking screw 5 and a locking hole 6 together, the valve body 4 is indirectly fixed to the compressor body, thus solving the problem of body wear caused by directly disassembling the compressor body connecting parts when frequently replacing valves.

[0026] Working principle: When using this compressor exhaust valve plate assembly, firstly, install the mounting base 1 onto the compressor body through the bolt holes 8 on the fixing block 1 7. When it is necessary to install the valve plate body 4, place the mounting plate 3 into the mounting groove 2 of the mounting base 1, and perform preliminary positioning through the positioning mechanism. That is, the positioning inclined blocks 14 on both sides of the mounting plate 3 and the positioning rod 16 at its bottom end will be inserted into the positioning hole 15 at the top of the mounting base 1, ensuring that the mounting plate 3 is accurately positioned. Then, tighten the locking screw 5 on the fixing block 2 18, so that its end is screwed into the locking hole 6 of the mounting base 1, thereby firmly locking the mounting plate 3 onto the mounting base 1. When it is necessary to adjust the height of the valve plate body 4, rotate the adjusting screw 11. Since the adjusting screw 11 is connected to the bearing... The lifting block 9 is rotatably connected to the lifting block 9 and threadedly engaged with the mounting plate 3. Therefore, the rotational motion is converted into the vertical movement of the lifting block 9. The lifting block 9 drives the valve body 4 to rise and fall synchronously. At the same time, the guide rod 12 on the lifting block 9 slides in the movable hole 13 of the mounting plate 3 to ensure that the valve body 4 moves smoothly and does not deflect. The limiting inclined plate 10 further restricts the rotation of the lifting block 9 to ensure that the valve body 4 always maintains the correct angle. When the valve body 4 pops up, the gas in the area below it can be quickly discharged from the vent grooves 17 on both sides of the bottom of the fixed seat 1. When the valve body 4 needs to be replaced due to long-term deformation and damage, simply loosen the locking screw 5 to remove the entire mounting plate 3 along with the valve body 4 from the fixed seat 1 for replacement.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
