Description

Technical Field

[0001] The utility model relates to flow regulation of an air compressor, in particular to a flow regulation mechanism of an air compressor, and belongs to the technical field of air compressors. Background Art

[0002] An air compressor, also known as an air compressor, is a device used to compress gas. The internal structure of an air compressor is similar to that of a water pump. Most types are divided into reciprocating piston type, rotary vane type, and rotary screw type. The air compressor discharges the compressed air from the outlet pipe for use in industrial production, and the flow rate and speed of the discharged air need to be controlled through the corresponding flow regulating port.

[0003] Conventional flow regulating ports mainly control the movement of the flow-limiting components inside them, and then adjust the flow through the flow-limiting components. The most common method is to perform loading / unloading control through a valve, that is, ON / OFF control. This control method is simple and direct, but it will cause severe pressure fluctuations in the air compressor and aggravate the wear inside the air compressor. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an air compressor flow regulating mechanism capable of slowing down pressure fluctuations.

[0005] In order to solve the above technical problems, the utility model provides an air compressor flow regulating mechanism, including a regulating device and a flow discharge device, wherein the regulating device includes a flow limiting component and a control component, wherein the flow limiting component is used to uniformly adjust the air flow rate in the regulating device, and the control component is connected to the flow limiting component, and the control component is used to control the flow limiting component to limit the flow;

[0006] The discharge device includes a closing cavity and a connecting port, the connecting port is connected to the regulating device, the connecting port seals and connects the regulating device and the closing cavity, the air outlet of the closing cavity is provided with an openable sealing cover, the sealing cover controls the closed state of the closing cavity, under the same air flow rate, the air flow rate passing through the sealing cover is the same as the air flow rate blocked by the flow limiting component.

[0007] The flow limiting assembly of the present invention includes two flow limiting plates and a flow limiting cavity with the same structure. The two flow limiting plates can be movably fitted together and arranged in the flow limiting cavity. A plurality of transverse flow limiting holes are evenly arranged on the flow limiting plates. The aperture of the flow limiting holes on one of the flow limiting plates through which the airflow can pass is interfered by the other flow limiting plate. The flow limiting assembly as a whole is a sealed cavity structure.

[0008] The two flow limiting plates of the utility model are connected by a connecting shaft, and the connecting shaft is set at the center of the two flow limiting plates. The two flow limiting plates rotate around their centers. During the rotation, the aperture size of the two flow limiting holes combined for the air flow to pass through changes with the rotation of the flow limiting plates, and the connecting shaft is fixedly connected to the inner wall of the flow limiting cavity.

[0009] The utility model provides a separable sealing assembly at the connection between the two limiting plates and the outer wall of the limiting plates. When the limiting plates rotate, the sealing assembly separates and the limiting plates are located between the sealing assemblies. When the limiting plates do not rotate, the sealing assembly seals the connection between the limiting plates and the limiting cavity.

[0010] The control assembly of the utility model comprises a control handle, which is arranged on the outside of the two limiting plates, and controls the rotation of the limiting plates.

[0011] The outer wall of the air outlet of the closing cavity of the utility model is provided with an external thread. When air flows through the flow limiting cavity, the closing cavity is in a closed state. When the flow limiting cavity is in the closed state, the closing cavity is in a flow state.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with conventional valve control, the regulating device that can uniformly regulate the airflow can gradually reduce the airflow entering the regulating device to avoid violent airflow fluctuations. At the same time, the leakage device gradually opens, and the airflow blocked by the regulating device is discharged from the leakage device, maintaining the airflow stability of the entire regulating mechanism.

[0014] 2. The two flow restrictors interfere with each other and block the flow restricting holes on each other's flow restrictors, thereby limiting the air flow through the flow restrictors. Compared with conventional valve control, the method of gradually reducing the aperture of the flow restricting holes can effectively alleviate the air flow fluctuations in the air compressor.

[0015] 3. Both limiting plates move with the center of the limiting plate as the moving point, which can minimize the movement volume occupied by the limiting plate in the limiting cavity, ensure that the limiting holes on the entire limiting plate can be gradually reduced, avoid the situation where a large number of limiting holes are suddenly opened or closed, and ensure that the entire limiting assembly can gradually reduce the air flow inside it;

[0016] 4. The discharge device can gradually open while the flow limiting component gradually closes, maintaining the total air output of the entire regulating mechanism, reducing the air flow fluctuation inside the entire air compressor, and ensuring that the entire air compressor can be in a relatively stable airflow outflow state.

[0027] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0028] like Figure 1 、 2 As shown, the air compressor flow regulating mechanism in this embodiment includes a regulating device and a flow discharge device. The regulating device includes a flow limiting component and a control component. The flow limiting component is used to uniformly adjust the air flow rate in the regulating device. The control component is connected to the flow limiting component and is used to control the flow limiting component to limit the flow.

[0029] The discharge device includes a closing chamber 4 and a connecting port, the connecting port is connected to the regulating device, the connecting port seals and connects the regulating device and the closing chamber 4, and the air outlet of the closing chamber 4 is provided with an openable sealing cover 5, which controls the closed state of the closing chamber 4. Under the same air flow rate, the air flow passing through the sealing cover 5 is the same as the air flow blocked by the flow limiting component.

[0030] The regulating device can adjust the air flow at a uniform speed, gently reduce the air flow entering the regulating device, and avoid violent air flow fluctuations. At the same time, the discharge device gradually opens, and the air flow blocked by the regulating device is discharged from the discharge device, maintaining the air flow stability of the entire regulating mechanism, maintaining the total air output of the entire regulating mechanism, reducing the air flow fluctuations inside the entire air compressor, and ensuring that the entire air compressor can be in a relatively stable airflow outflow state.

[0031] In this embodiment, the flow limiting assembly includes two flow limiting plates 2 and a flow limiting cavity 1 with the same structure. The two flow limiting plates 2 can be movably fitted together and arranged in the flow limiting cavity 1. A plurality of transverse flow limiting holes 6 are evenly arranged on the flow limiting plates 2. The flow limiting holes 6 on one flow limiting plate 2 allow the airflow to pass through, which is interfered with by the other flow limiting plate 2. The flow limiting assembly as a whole is a sealed cavity structure.

[0032] In this embodiment, the two flow limiting plates 2 are connected by a connecting shaft 8, which is arranged at the center of the two flow limiting plates 2. The two flow limiting plates 2 rotate around their centers. During the rotation, the aperture size of the two flow limiting holes 6 for the air flow to pass through changes with the rotation of the flow limiting plates 2, and the connecting shaft 8 is fixedly connected to the inner wall of the flow limiting chamber 1.

[0033] To facilitate connection, a connection groove is provided at the connection between the flow limiting plate 2 and the flow limiting chamber 1. This not only facilitates the connection between the flow limiting plate 2 and the flow limiting chamber 1, but also facilitates the rotation of the flow limiting plate 2. In addition, a sealing ring is provided on the outer side of the connection between the two flow limiting plates 2 to prevent air leakage between the flow limiting plates 2.

[0034] In this embodiment, a separable sealing assembly 3 is provided at the connection between the two flow limiting plates 2 and the outer wall of the flow limiting plates 2. When the flow limiting plates 2 rotate, the sealing assembly 3 separates and the flow limiting plates 2 are located between the sealing assemblies 3. When the flow limiting plates 2 do not rotate, the sealing assembly 3 seals the connection between the flow limiting plates 2 and the flow limiting cavity 1.

[0035] In this embodiment, the control component includes a control handle 7, which is connected to the outer side of the flow limiting plate 2. The control handle 7 is provided with rotating teeth on the outer side of the flow limiting plate 2 in this embodiment. The rotating teeth are engaged with the outer side of the control handle 7. When the control handle 7 rotates, the flow limiting plate 2 is driven to rotate.

[0036] In this embodiment, the outer wall of the air outlet of the closing chamber 4 is provided with an external thread. When air flows through the closing chamber 4 in the flow limiting chamber 1, the closing chamber 4 is in a closed state. When the flow limiting chamber 1 is in a closed state, the closing chamber 4 is in a flow state.

[0037] When this embodiment is actually used and in normal working state, the flow limiting plate 2 can be rotated by controlling the turning handle 7 to adjust the air flow passing through the flow limiting cavity 1, and the air flow fluctuation in the air compressor can be effectively alleviated.

[0038] In the above description, many specific details are set forth to facilitate a full understanding of the present invention. However, the above examples are merely preferred implementations of the present invention and cannot be used to limit the scope of rights of the present invention. Simple modifications and equivalent changes made to the above examples based on the essence of the present invention still fall within the scope of the present invention.
