Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically a compressor valve plate structure for conveying corrosive gases. Background Technology

[0002] The compressor valve is an important component in the compressor used to control the timely intake and discharge of gas from the cylinder; the valves on the piston compressor are all automatic valves, that is, the opening and closing of the valve is not achieved by a forced mechanism but by the pressure difference on both sides of the valve plate (the gas pressure difference between the cylinder and the valve chamber);

[0003] During use, the valve disc is subjected to multiple impacts, which often cause damage to the disc. Usually, only a small part of the disc's edge is damaged. Replacing the entire disc would result in significant economic losses and waste of resources.

[0004] Chinese patent discloses a valve plate for a compressor valve (authorization announcement number CN215719361U). This patented technology, through the setting of a first fixing ring, a second fixing ring, and a concave sliding groove, allows the valve plate body to operate within the valve. A second spring between the two arc-shaped sliding blocks reduces the impact force on the valve plate body. Furthermore, a third spring inside the concave sliding groove simultaneously dampens the arc-shaped sliding blocks on both sides, thus dissipating the impact force from within and dispersing it evenly. This prevents damage to the valve plate body, thus preventing it from becoming unusable. If the first and second fixing rings are damaged after prolonged use, simply rotating the second fixing ring allows the arc-shaped sliding block on it to slide down from the other end of the concave sliding groove, enabling easy replacement. Only a small portion needs to be replaced, ensuring efficient resource utilization and preventing waste.

[0005] However, it has certain drawbacks: the first fixed ring and the second fixed ring adopt a concave groove and arc-shaped sliding block insertion structure. The two ends of the concave groove are arc-shaped, which makes it easy for the arc-shaped sliding block to slide in, but it lacks a rigid limiting structure and only relies on the elastic force of the spring to maintain contact. This causes the two rings to easily rotate or slip under high-frequency impact or vibration conditions, resulting in loose connection or even misalignment, which in turn affects the sealing stability of the valve plate and the air valve.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A compressor valve plate structure for conveying corrosive gases includes an inner valve plate ring and an outer valve plate ring movably sleeved on the outer surface of the inner valve plate ring. Both the inner and outer valve plate rings are made of corrosion-resistant materials.

Detailed Implementation

[0022] Please see Figure 1 In this embodiment of the present invention, a compressor valve plate structure for conveying corrosive gas includes an inner valve plate ring 1 and an outer valve plate ring 2 that is movably sleeved on the outer surface of the inner valve plate ring 1. Both the inner valve plate ring 1 and the outer valve plate ring 2 are components made of corrosion-resistant material. A positioning hole 3 is provided at the center of the surface of the inner valve plate ring 1, and multiple air holes 4 are provided on the surface of the inner valve plate ring 1 outside the positioning hole 3.

[0023] The inner ring 1 and outer ring 2 of the valve plate are preferably made of super duplex stainless steel or nickel-based alloy, which have excellent corrosion resistance and are suitable for conveying corrosive gases.

[0024] The outer ring 2 of the valve plate is fixedly connected to other mechanisms of the compressor through the positioning hole 3.

[0025] exist Figures 1-4In the valve plate inner ring 1, both ends of the upper surface are provided with mating groove 1 5, and both ends of the upper surface of the valve plate outer ring 2 are provided with mating groove 2 6. A mating mechanism 7 is jointly provided inside adjacent mating grooves 1 5 and 2 6. The mating mechanism 7 includes a mating block 8, which is movably embedded in the lower surfaces of the valve plate inner ring 1 and outer ring 2. A mating rod 9 is fixedly connected to both ends of the upper surface of the mating block 8. One mating rod 9 movably penetrates the valve plate inner ring 1, with its upper end located in mating groove 1 5. The other mating rod 9 movably penetrates the valve plate outer ring 2, with its upper end located inside mating groove 2 6. A mating assembly 10 is provided at the upper end of the inner part of the mating rod 9. The mating assembly 10 includes a rotating rod 11, which is rotatably connected to the inside of the mating rod 9. A gear 12 is fixedly sleeved on the outside of the rod 11. A rack 13 is meshed on both the left and right sides of the gear 12. A spring 14 is fixedly connected to the rear surface of the left rack 13 and the front surface of the right rack 13. A slider 15 is fixedly connected to the end of the spring 14 away from the rack 13. The slider 15 is fixedly connected to the inside of the docking rod 9. A sliding rod 16 is movably connected to the inside of the slider 15 on both the upper and lower sides of the spring 14. One end of the sliding rod 16 is fixedly connected to the rack 13. A docking part 17 is provided on the front surface of the left rack 13 and the rear surface of the right rack 13. The docking part 17 includes a locking plate 18. The locking plate 18 is fixedly connected to the rack 13. A locking block 19 is fixedly connected to the side surface of the locking plate 18 away from the rack 13. The locking block 19 movably passes through one side surface of the docking rod 9.

[0026] The inner ring 1 and outer ring 2 of the valve plate are separate units, which are connected and fixed by the docking mechanism 7.

[0027] The upper end of the docking rod 9 has a cavity, and the docking mechanism 7 is disposed in the cavity;

[0028] The lower surface of the mating block 8 is flush with the lower surfaces of the inner ring 1 and outer ring 2 of the valve plate; the upper surface of the mating rod 9 is flush with the upper surfaces of the inner ring 1 and outer ring 2 of the valve plate.

[0029] The lower surface of the locking block 19 in one docking rod 9 is attached to the lower inner surface of the docking groove 1 5, and the lower surface of the locking block 19 in the other docking rod 9 is attached to the lower inner surface of the docking groove 2 6, thereby docking and fixing the inner ring 1 and outer ring 2 of the valve plate together.

[0030] Push one locking block 19 toward the docking rod 9. Under the action of the rack 13 and gear 12, the other locking block 19 will move toward the docking rod 9 until both locking blocks 19 are retracted into the docking rod 9. Then the docking mechanism 7 can be removed from the inner ring 1 and outer ring 2 of the valve plate, which makes it easier to disassemble the inner ring 1 and outer ring 2 of the valve plate.

[0031] The working principle of this utility model is as follows: When the compressor valve plate structure is in use, the inner ring 1 and the outer ring 2 of the valve plate are linked and cooperated through the docking mechanism 7; under normal working conditions, the locking block 19 inside the docking rod 9 pops outward under the action of the spring 14, and respectively locks into the docking groove 5 of the inner ring 1 and the docking groove 6 of the outer ring 2, and the inner and outer rings are fixedly connected by the engagement of the locking block 19 with the groove opening; when disassembly and maintenance are required, simply press any locking block 19 in the direction of the docking rod 9, at which time the rack 13 will... When the moving gear 12 rotates, the locking block 19 on the other side retracts synchronously through the gear and rack linkage mechanism. When both sets of locking blocks 19 are fully retracted into the docking rod 9, the entire docking mechanism 7 can be vertically pulled out to separate the inner ring 1 and outer ring 2 of the valve plate. When reassembling, press the locking block 19 to retract it. After the docking rod 9 is fully inserted into the docking groove 1 5 and docking groove 2 6, release the locking block 19. The spring 14 pushes the rack 13 to reset, and the locking block 19 pops out again and locks the groove, completing the quick locking of the inner and outer rings.
