Technical Field

[0001] The utility model relates to the technical field of compressor intake valves, in particular to an intake valve plate structure of a micro oil-free compressor. Background Art

[0002] An air intake and exhaust device with both large and small air intake and exhaust holes, which can quickly exhaust the air when the empty pipe is filled with water, and quickly take in air when negative pressure is generated in the pipe, and can discharge the trace air gathered in the pipe under working pressure.

[0003] In the existing market, gas compressors have gradually become part of our lives, such as kitchen range hoods. However, the design of the intake valve plates of oil-free compressors on the market today often lacks an accurate oil filter device. The entire intake valve plate is often disassembled and replaced as a whole, which increases the cost of use. In addition, the intake valve plate cannot be disassembled to clean the oil stains inside it during long-term operation, resulting in a poor air compression effect of the oil-free compressor, which cannot meet the needs of daily use.

[0004] Therefore, we provide an intake valve plate structure for a micro oil-free compressor. Utility Model Content

[0014] The utility model discloses that after the limit plate is inserted into the assembly rod, the filter plate is installed on the outside of the limit plate. The existence of the limit plate can limit the position of the filter plate. An oil filter groove is provided on the surface of the filter plate, and an oil absorption filter paper is installed inside the oil filter groove, which can filter the oil of the air absorbed from the outside and entering the compressor, and concentrate the grease in the air into the oil absorption filter paper to prevent the oily substances from entering the compressor when the compressor is compressing the air, thereby isolating and filtering the oil. When the intake valve plate is cleaned and the oil filter paper is replaced regularly, the airflow plate threadedly connected to the limit plate above can be disassembled by rotating the threaded rod threadedly connected to the upper end of the limit hole, so as to achieve the effect of detachable oil cleaning of the filter plate.

[0015] The utility model has an air flow plate that is threadedly screwed on the upper end of the limit plate, and a gas flow channel is opened on the surface of the air flow plate.

Through the provided circulation groove, the valve seat is located at the bottom layer of the valve plate. The compressed and filtered air will be transported through the circulation groove for air transportation. A spring can be installed inside it through the installation hole opened on the upper surface of the valve seat. The presence of the spring can reduce the buffering effect of the valve plate set on its upper end, prevent the valve plate from being damaged by gas vibration on the intake valve plate during gas transportation, and play a protective role.

[0016] According to the utility model, after the valve plate, the limit plate, the filter plate and the air flow plate are installed on the assembly rod, the screwing groove at the lower end is driven by the rotating bolt to be threadedly screwed with the assembly rod, so that it is fixed to the surface of the air flow plate located at the top, thereby achieving the effect of fixing and assembling the entire intake valve plate.

[0026] Example 1: A micro oil-free compressor intake valve plate structure, such as Figure 1-Figure 5As shown, it includes a valve seat 1 and several valve discs 2 arranged above the valve seat 1, a filter plate 3 is arranged above the valve disc 2, and several oil filter grooves 13 are opened on the surface of the filter plate 3, a limit plate 14 is arranged inside the filter plate 3, and several limit holes 16 are opened on the upper surface of the limit plate 14. The internal threads of the limit holes 16 are screwed together with threaded rods 15, and a plug hole 19 is opened on the surface of the limit plate 14. When the compressor intake valve plate is manufactured, the filter plate 3 is tightly installed on the upper end of the valve disc 2. The existence of the valve disc 2 can transport the filtered gas. When the filter plate 3 is installed, the limit plate 14 is first plugged and installed with the assembly rod 12 through the plug hole 19. After the limit plate 14 is plugged into the assembly rod 12, the filter plate 3 is installed on the outside of the limit plate 14. The existence of the limit plate 14 can limit the position of the filter plate 3. The surface of the filter plate 3 is provided with an oil filter groove 13. The interior of 13 is equipped with oil-absorbing filter paper, which can filter the oil in the air absorbed from the outside and enter the compressor, and absorb the grease in the air into the oil-absorbing filter paper to prevent the oil from entering the compressor when the compressor is compressing the air, thereby isolating the oil filter. When the intake valve plate is cleaned and the oil filter paper is replaced regularly, the air flow plate 4 threadedly connected to the upper end of the limit hole 16 can be disassembled by rotating the threaded rod 15 threadedly connected to the upper end of the limit hole 16 to achieve the effect of detachable oil cleaning of the filter plate 3.

[0027] like Figure 1-Figure 5 The air that is sucked in will first pass through the gas flow channel 5 and then enter the surface of the filter plate 3, and the air flow plate 4 is threadedly screwed on the upper end of the limit plate 14 through the threaded rod 15 to be screwed and installed with the limit plate 14 through the assembly hole 7 opened on the upper surface. Through the provided circulation grooves 11, the air that is compressed and filtered by the valve seat 1 at the bottom layer of the valve plate will be transported through the circulation grooves 11 for air transportation. Through the mounting holes 9 opened on the upper surface of the valve seat 1, a spring 8 can be installed inside it. The presence of the spring 8 can reduce the buffering effect of the valve plate 2 set on its upper end, preventing the valve plate 2 from being damaged by gas vibration on the intake valve plate during gas transportation, thereby playing a protective role.

[0028] like Figure 1-Figure 5As shown, a mounting assembly 10 is fixedly installed on the upper surface of the valve seat 1, and an assembly rod 12 is fixedly installed inside the mounting assembly 10. By fixing the mounting assembly 10 on the upper surface of the valve seat 1, the assembly rod 12 can be fixedly installed inside it. The existence of the assembly rod 12 allows the valve plate 2, the limit plate 14 and the airflow plate 4 to be inserted into the surface of the assembly rod 12 for unified assembly and fixation, thereby achieving an assembly effect.

[0029] Example 2: A micro oil-free compressor intake valve plate structure, such as Figure 1-Figure 5 As shown, the upper end of the assembly rod 12 is threadedly screwed into a screw groove 18, and the upper end of the screw groove 18 is fixedly installed with a bolt 6. After the valve plate 2, the limit plate 14, the filter plate 3 and the air flow plate 4 are installed on the assembly rod 12, the screw groove 18 at the lower end is driven by rotating the bolt 6 to be threadedly screwed into the assembly rod 12, so that it is fixed to the surface of the air flow plate 4 located at the top, so as to achieve the effect of fixing the assembly of the entire intake valve plate.

[0030] like Figure 1-Figure 5 As shown, a plurality of gas flow channels 5 are opened on the surface of the air flow plate 4, and a plurality of assembly holes 7 are opened on the surface of the air flow plate 4. The gas flow channels 5 opened on the air flow plate 4 can achieve the effect of air transportation. The air can enter the filter plate 3 at the lower end through the gas flow channels 5 to centrally filter the oil stains in the air. Through the provided assembly holes 7, the limit plate 14 and the air flow plate 4 can be threadedly screwed together through the threaded rod 15 to achieve the effect of assembly and fixing.

[0031] Working principle: When the compressor intake valve plate is manufactured, the filter plate 3 is tightly installed on the upper end of the valve plate 2. The existence of the valve plate 2 can transport the filtered gas. When the filter plate 3 is installed, the limit plate 14 is first plugged and installed with the assembly rod 12 through the plug hole 19. After the limit plate 14 is plugged into the assembly rod 12, the filter plate 3 is installed on the outside of the limit plate 14. The existence of the limit plate 14 can limit the position of the filter plate 3. The surface of the filter plate 3 is provided with an oil filter groove 13, and the inside of the oil filter groove 13 is installed with oil absorbing filter paper, which can filter the oily air absorbed from the outside into the compressor and remove the oil in the air. The existing grease is absorbed in the oil-absorbing filter paper, preventing oily substances from entering the compressor when the compressor is compressing air, thereby isolating the oil filter. When the intake valve plate is cleaned and the oil filter paper is replaced regularly, the airflow plate 4 threadedly connected to the upper end of the limit hole 16 can be disassembled by rotating the threaded rod 15 threadedly connected to the upper end of the limit hole 16 to achieve the effect of detachable oil cleaning of the filter plate 3. The airflow plate 4 threadedly connected to the upper end of the limit plate 14 is provided with a gas flow channel 5 on the surface of the airflow plate 4. The air absorbed in will first pass through the gas flow channel 5 and then enter the surface of the filter plate 3. , the air flow plate 4 is threadedly screwed and installed with the limit plate 14 through the assembly hole 7 opened on the upper surface through the threaded rod 15. Through the provided circulation groove 11, the valve seat 1 is located at the bottom layer of the valve plate. The air after compression and filtration is completed will be transported through the circulation groove 11. The spring 8 can be installed inside it through the mounting hole 9 opened on the upper surface of the valve seat 1. The presence of the spring 8 can reduce the buffering effect of the valve plate 2 set on its upper end, preventing the valve plate 2 from being damaged by gas vibration when the gas is transported. The valve plate 2, the limit plate 14 and the air flow plate 4 can be inserted into the assembly rod 12. The surface of the rod 12 is uniformly assembled and fixed to achieve an assembly effect. The rotating bolt 6 drives the screwing groove 18 at the lower end to be threadedly screwed with the assembly rod 12, so that it is fixed to the surface of the airflow plate 4 at the top, so as to achieve the effect of fixed assembly of the entire intake valve plate. The gas flow channel 5 opened on the airflow plate 4 can achieve the effect of air transportation. The air can enter the filter plate 3 at the lower end through the gas flow channel 5 to centrally filter the oil stains in the air. The limit plate 14 can be threadedly screwed with the airflow plate 4 through the threaded rod 15 through the provided assembly hole 7, which achieves the effect of assembly and fixing.
