Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separators, in particular to a novel oil-gas separator core. Background Art

[0002] The oil-gas separator in the air compressor is a key component, which is mainly used to separate the oil and gas in the compressed air. During the air compression process, the lubricating oil will be compressed together with the gas, and then separated by the oil-gas separator to ensure the purity of the compressed air.

[0003] The working principle of the oil-gas separator is: when the compressed oil-gas mixture enters the oil-gas separator, due to the effects of gravity and centrifugal force, the lubricating oil will settle to the bottom of the separator, while the gas will be discharged through the outlet. The performance of the oil-gas separator directly affects the quality of the compressed air and the operating efficiency of the compressor. If the oil-gas separator does not work well, it will cause the compressed air to contain too much oil, affecting the use of subsequent processes and even damaging the equipment.

[0004] At present, the compressed oil-gas mixture directly enters the oil-gas separator. The gas flow rate at the air inlet is relatively large, while the air flow away from the air inlet is relatively small, and there is an uneven gas distribution. This makes the utilization rate of the separator core part close to the air inlet relatively high during filtration, while the utilization rate of the separator core part far from the air inlet is relatively low. As the use time increases, the separation efficiency of the area with high utilization rate decreases, and it may even be incompletely filtered, affecting the purity of the subsequent output gas source. The uneven air flow distribution will also cause relatively large noise. In addition, the high-pressure gas generated is to provide a gas source for other subsequent equipment. In addition to the requirements for the purity of the gas source, it is also required to have a stable output pressure. The pressure output end of the current oil-gas separator is directly connected to the gas-using equipment through a gas pipe, and a manual valve is set on the output port to realize switch control. The output pressure of the gas outlet of this structure will cause unstable pressure due to the fluctuation of gas separation efficiency, and when the gas generation is stopped, the impurities at the gas-using end will flow back to the oil-gas separator with the gas, causing the oil-gas separator to be blocked.

[0005] Therefore, it is urgent to provide a novel oil-gas separator core. Utility Model Content

[0038] like Figure 6 As shown, the pressure-maintaining check assembly 3 includes a cylinder body 3.1, a pressure-maintaining spring 3.2, a pressure-maintaining valve core 3.3, a check valve core 3.4 and a check spring 3.6.

[0039] like Figure 6As shown, in order to achieve the seal between the housing and the oil separator seat 2, it also includes a first sealing ring 12 and a sixth sealing ring 15, and the first sealing ring 12 and the sixth sealing ring 15 are both arranged on the connection surface between the housing and the oil separator seat 2 to achieve the seal between the housing and the oil separator seat 2. Preferably, the first sealing ring 12 and the sixth sealing ring 15 are respectively arranged on two contact surfaces at 90°. In this embodiment, the first sealing ring 12 is located on the internal vertical contact surface, and the sixth sealing ring 15 is located on the external horizontal contact surface. In order to achieve the seal when the oil-gas separator is installed with other components, it also includes a third sealing ring 14, which is arranged on the bottom of the oil separator seat 2 and the installation surface of other components of the oil-gas separator. Specifically, the oil separator seat 2 on the outside of the annular groove forms an outer sleeve connected to the outer shell 1, and a flange is provided on the outer wall of the shell. The lower end of the shell is inserted into the annular groove, and the flange is supported on the upper end surface of the outer sleeve; an inner sleeve is formed on the oil separator seat 2 on the inner side of the annular groove, and the outer wall of the inner sleeve is stepped, and the inner bottom surface of the lower end cover 6 of the oil separator core assembly is attached to the upper end surface of the inner sleeve, and the flow equalizer 4 is sleeved on the outside of the inner sleeve through its central through hole 4.3, and the edge of the cap body 4.1 close to the central through hole 4.3 is supported on the step of the outer wall of the inner sleeve; the flow equalizer 4 divides the annular groove into upper and lower parts, and the lower part and the oil separator seat 2 are a steady flow cavity 16.

[0040] Working principle:

[0041] like Fig.12 As shown, the air flow enters the steady flow chamber 16 from the air inlet 2.7, is stabilized in the steady flow chamber 16, and then enters the air inlet channel 20 through the flow equalizing hole 4.4 on the flow equalizing plate 4. The air flow flows from bottom to top along the air inlet channel 20, and at the same time the air flow passes inward through the oil separator core assembly for fine separation, converges inside the oil separator core assembly, and then passes through the oil separator rod 11 to enter the air outlet chamber 17. When the pressure in the air outlet chamber 17 reaches a certain value, the pressure in the air outlet chamber 17 pushes the check valve core 3.4 to move outward to compress the check spring 3.6, and pushes the pressure maintaining valve core 3.3 through the check spring 3.6 to compress the pressure maintaining spring 3.2, thereby opening the pressure maintaining check assembly 3, so that the air outlet chamber 17 is connected to the air outlet 2.2, and the finely separated gas is output to the user for use, and the separated oil returns to the screw main unit through the secondary oil return port 2.4.

[0042] When high-pressure gas is no longer needed and the internal pressure disappears, the pressure-maintaining valve core 3.3 and the check valve core 3.4 are restored under the elastic force of the pressure-maintaining spring 3.2 and the check spring 3.6, the pressure-maintaining check assembly 3 is closed, the gas outlet cavity 17 is disconnected from the gas outlet 2.2, and no gas is output. At this time, the check spring 3.6 presses the check valve core 3.4 against the inner convex ring and seals it through the fifth sealing ring 3.7 to prevent the outlet pressure of the gas outlet 2.2 from being greater than the internal pressure and causing backflow.

[0043] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
