Description

Technical Field

[0001] The utility model relates to the technical field of air compressor accessories, and more specifically to an air inlet and outlet chamber of a compressor. Background Art

[0002] The air inlet and outlet valve group of air compression is an important component in the machine, and its performance determines the overall performance of the air compressor. Currently, the air inlet and outlet valves of the air compressor are usually arranged on the cylinder head, and the valve group is sealed with an O-ring. Since the valve group has high requirements for sealing performance, high precision and assembly requirements for each component, the machining cost of the existing air inlet and outlet valve group is relatively high, and the assembly is also relatively complex;

[0003] Moreover, when the current air inlet and outlet valve group is installed on a double-cylinder compressor, the air inlet and outlet work independently. For example, the utility model patent with the publication number of CN201723415U discloses an air inlet and outlet valve group of an air compressor, including a cylinder head, an air inlet and an air outlet are arranged on the cylinder head, and air inlet and outlet valve group installation holes are respectively arranged at positions corresponding to the air inlet and outlet. The air inlet valve group from bottom to top is respectively a copper gasket, an air inlet valve, an air inlet bracket, a paper gasket, an air inlet gland, a top bolt and a locking nut, and the air outlet valve group from bottom to top is respectively a copper gasket, an exhaust valve, an exhaust bracket, a paper gasket, an exhaust gland, a top bolt and a locking nut;

[0004] When the above air inlet and outlet chamber is applied to a double-cylinder compressor, each air inlet and outlet chamber works independently, and each air inlet and outlet needs to be connected with a pipeline, which will lead to an increase in the overall volume of the compressor and a decrease in the actual working efficiency of the compressor at the same time. Content of the Utility Model

[0005] In order to solve the above problems, the utility model provides an air inlet and outlet chamber applicable to a double-cylinder compressor.

[0006] To achieve the above object, the utility model provides the following technical solutions, mainly including:

[0009] Preferably, a plurality of radiating fins are arranged on the upper side of each air chamber cover, and the radiating fins and the air chamber cover are of an integral structure.

[0010] Preferably, a connecting block is provided on the lower side of each air chamber cover. The connecting block and the air chamber cover are of an integral structure. An air inlet is provided on the lower side of the connecting block. The air inlet is of a U-shaped structure, and one end of the U-shaped structure inclines inwards. An air outlet is also formed on the lower side of the connecting block. The air outlet communicates with an air outlet pipe. A through hole is also formed on one side of the connecting block. The position of the through hole corresponds to that of an air inlet pipe.

[0011] Preferably, a first ventilation hole and a second ventilation hole are successively formed on the upper side of each pressure cover. The first ventilation hole is of a horseshoe shape. The first ventilation hole corresponds to the air outlet. The second ventilation hole corresponds to the air inlet.

[0012] Preferably, a gasket is further included. The gasket is located between the air chamber cover and the pressure cover. Two U-shaped holes are symmetrically formed on the gasket. The U-shaped holes respectively correspond to the air inlet and the first ventilation hole.

[0013] Preferably, a sealing ring is further included. The sealing ring is located between the air chamber cover and the pressure cover. The shape of the sealing ring is consistent with the shape of the inner edge of the air chamber cover.

[0014] It can be seen from the above technical solutions that, compared with the prior art, the present utility model is fixedly connected to the cylinder of a twin-cylinder compressor through bolts. In the working state, the air inlet pipes of the two air chamber assemblies simultaneously inject gas into the compressor through a three-way pipe, and at the same time, the gas is also synchronously discharged through the three-way pipe on the air outlet pipe, thereby ensuring that the two air chamber assemblies can synchronously perform the air intake and exhaust operations, thereby improving the working efficiency of the compressor, reducing the vibration generated during air intake and exhaust, and increasing the stability of the compressor during operation.

An air outlet 1042 is further opened on the lower side of the connecting block 104, the air outlet 1042 is communicated with the air outlet pipe 102, and a through hole 1043 is further opened on one side of the connecting block 104, and the position of the through hole 1043 corresponds to the air inlet pipe 103.

[0026] In order to further optimize the above solution, a first ventilation hole 301 and a second ventilation hole 302 are successively formed in the upper side of each gland 3. The first ventilation hole 301 is in a horseshoe shape, the first ventilation hole 301 corresponds to the air outlet 1042, and the second ventilation hole 302 corresponds to the air inlet 1041.
