Abstract
Description
Technical Field
[0001] This utility model relates to an interleaved diagonal gas path structure for a piston compressor. Background Technology
[0002] A reciprocating compressor operates by continuously changing the working volume formed by the cylinder, valves, and the piston reciprocating within the cylinder. If we disregard volumetric and energy losses during actual operation (i.e., the ideal working process), the work completed by the crankshaft of a reciprocating compressor per revolution can be divided into intake, compression, and exhaust processes.
[0003] The airflow direction of a piston compressor plays a crucial role in the compressor's operation. Its design directly affects the compressor's performance and reliability. Optimizing airflow distribution and enhancing structural stability are important prerequisites for ensuring the smooth and efficient operation of compressor components. In the current technology, the air path structure design of piston compressors is not reasonable enough, and the reliability is relatively poor. It cannot provide a stable and uniform airflow distribution for the piston compressor, thereby ensuring the stable and efficient operation of the compressor. Utility Model Content
[0004] This invention addresses the aforementioned problem by providing an alternating diagonal airflow structure for a piston compressor, which offers a stable and uniform airflow distribution, thereby ensuring stable and efficient compressor operation.
[0005] The utility model is constructed as follows: it includes two cylinders and a valve plate body disposed above the two cylinders. Two air intake chambers and one air exhaust chamber are disposed above the valve plate body. The two air intake chambers are arranged diagonally. Each air intake chamber is connected to each cylinder via an air intake valve plate. The air intake chamber and the air exhaust chamber are connected via an air exhaust valve plate. Each air intake chamber is provided with an air intake port.
[0006] Furthermore, the intake valve plates at different intake chambers are set diagonally.
[0007] Furthermore, the exhaust valve plates at different cylinders are set diagonally.
[0008] Furthermore, the air inlet of the air intake chamber is arranged diagonally.
[0009] Furthermore, the intake valve plate is disposed on the lower surface of the valve body plate, and the exhaust valve plate is disposed on the upper surface of the valve body plate.
[0010] Furthermore, a cylinder head is provided above the valve plate, and the exhaust chamber and intake chamber are located in the inner cavity of the cylinder head.
[0011] Furthermore, an exhaust port is provided on the exhaust chamber.
[0012] Furthermore, the intake valve plate is made of metal spring sheet or elastic polymer material.
[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) The device has a simple structure, reasonable design, and is easy to use. The low-pressure gas flows from the chamber where the cylinder liner is located to the inlet of the valve plate, passes through the inlet chamber of the cylinder head, enters the cylinder through the inlet valve plate, is compressed in the cylinder, enters the exhaust chamber of the cylinder head through the exhaust valve plate, the airflow converges in the exhaust chamber, and is discharged from the compressor through the exhaust port on the outer wall of the cylinder head. This is the process of gas flow inside the compressor. This utility model arranges the air inlets of the valve plate body diagonally to make the airflow in the cylinder outer wall cavity symmetrically distributed, which can uniformly cool the cylinder, avoid the generation of local high temperature or low temperature phenomena in the cylinder, ensure that the cylinder operates within a suitable temperature range, and improve the efficiency and reliability of the compressor; (2) This utility model divides the inner cavity of the cylinder head into three parts, consisting of two air inlets and one exhaust chamber. The air inlet chamber contains low temperature and low pressure gas, and the exhaust chamber contains high temperature and high pressure gas. Therefore, the two air inlets are arranged diagonally to achieve the purpose of balancing pressure and temperature; (3) The structure of this utility model adopts the integrated air circuit technology of two cylinders sharing one valve plate and cylinder head to form a compact and efficient gas compression unit. The two cylinders share one valve plate and cylinder head to coordinate the gas compression process, realize precise air intake and exhaust operation, and thus ensure the stable operation of the entire compression system. The air passage is cleverly arranged in a diagonal manner so that the air intake and exhaust processes can be reasonably separated in space, aiming to stabilize the airflow, balance the temperature, and balance the air pressure to ensure the overall stable, reliable, and efficient operation of the compressor.

Detailed Implementation
[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0016] Example: Figure 1-3As shown, an interleaved diagonal air passage structure for a piston compressor is provided, comprising two cylinders 5 and a valve plate 3 disposed above the two cylinders. The two cylinders share a valve plate. Two intake chambers 6 and one exhaust chamber 7 are disposed above the valve plate. The two intake chambers are diagonally disposed. Each intake chamber is connected to each cylinder via an intake valve plate 4. The intake chamber and the exhaust chamber are connected via an exhaust valve plate 2. Each intake chamber is provided with an intake port 9.
[0017] During operation: Low-temperature, low-pressure gas flows from the chamber containing the cylinder liner to the inlet 31 of the valve plate, passes through the intake chamber of the cylinder head, enters the cylinder through the intake valve plate, is compressed inside the cylinder, and then enters the exhaust chamber of the cylinder head through the exhaust valve plate. The airflow converges in the exhaust chamber and is then discharged from the compressor through the exhaust port on the outer wall of the cylinder head. This is the gas flow process inside the compressor. This invention, by staggering the diagonal arrangement of the inlets of the valve plate, ensures symmetrical airflow distribution within the cylinder's outer wall chamber, enabling uniform cooling of the cylinder and preventing localized high or low temperatures. This ensures the cylinder operates within a suitable temperature range, improving compressor efficiency and reliability.
[0018] In this embodiment of the invention, the intake valve plates at different intake chambers are arranged diagonally.
[0019] In this embodiment of the invention, the exhaust valve plates at different cylinders are arranged diagonally.

[0022] In this embodiment of the utility model, a cylinder head 1 is provided above the valve plate body. The exhaust chamber and the intake chamber are located in the inner cavity of the cylinder head. The inner cavity of the cylinder head is divided into three parts, namely two exhaust chambers and one intake chamber. The intake chamber contains low-temperature and low-pressure gas, and the exhaust chamber contains high-temperature and high-pressure gas. Therefore, the two intake chambers are arranged diagonally to achieve the purpose of balancing pressure and temperature.
[0023] In this embodiment of the invention, an exhaust port 8 is provided on the exhaust chamber.
[0024] In this embodiment of the invention, the intake valve is made of a metal spring or an elastic polymer material, which can open during intake to allow airflow to flow smoothly into the cylinder; the exhaust valve is also designed to open during intake to allow airflow to flow smoothly into the cylinder. Furthermore, a piston is provided inside the cylinder, which is prior art and will not be described in detail here.
[0025] The aforementioned air intake chamber is also provided with an outlet, and the exhaust chamber is provided with an inlet. The outlet and inlet are respectively matched with the exhaust valve plate and the air intake valve plate.
