Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a quantitative pressurized oil-gas mixer that can achieve good oil-gas mixing, lubrication, and friction reduction effects.

[0006] The objective of this utility model can be achieved through the following technical solution: A quantitative pressurized oil-gas mixer, comprising a housing, characterized in that the housing is provided with an oil inlet hole, and the housing has a plurality of oil inlet channels all connected to the oil inlet hole. Each oil inlet channel is provided with a pressurized quantitative distributor. The pressurized quantitative distributor has a connector with an axially penetrating oil outlet channel.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this quantitative pressurized oil-gas mixer includes a housing 1, which has an oil inlet 2. One end of the oil inlet 2 is connected to an oil inlet connector, and the other end of the oil inlet 2 is threaded with a plug. The housing 1 has three oil inlet channels 3, all of which are connected to the oil inlet 2. Each oil inlet channel 3 is equipped with a pressurized quantitative distributor 4. The pressurized quantitative distributor 4 has a connector 41 with an axially penetrating oil outlet channel 5. The connector 41 is connected to a connecting seat 6 that extends into the oil outlet channel 5 and is axially penetrating. An air inlet channel is provided between the housing 1 and the connecting seat 6, leading to each connecting seat 6. The housing 1 is equipped with an adjustment mechanism for adjusting the flow rate of each air inlet channel.

[0020] When this quantitative pressurized oil-gas mixer is in use, lubricating oil enters through the oil inlet 2, then passes through each oil inlet channel 3 and enters each pressurized quantitative distributor 4. Each pressurized quantitative distributor 4 delivers the lubricating oil to the oil outlet channel 5 of the connector 41. The air inlet channel delivers gas to each connecting seat 6. The lubricating oil enters the connecting seat 6 and mixes with the gas, thus spraying the mixed oil and gas out from the connecting seat 6. The flow rate of each air inlet channel can be adjusted by the adjustment mechanism, which can adjust the ratio of gas and lubricating oil to achieve an ideal mixing state. This achieves oil-gas mixing, enabling multi-point lubrication. The mixed oil and gas achieves gas atomization, resulting in a large lubrication area, easy formation of a lubricating oil film, and good lubrication and friction reduction efficiency.

[0021] To elaborate further, the oil outlet channel 5 is equipped with a one-way check valve that allows lubricating oil to flow into the connecting seat 6. This prevents lubricating oil backflow and ensures good operational stability.

[0022] The one-way check valve assembly includes a steel ball 7 and a spring 8. The oil outlet channel 5 has a shoulder 9 for the steel ball 7 to abut against. The spring 8 acts on the steel ball 7, causing the steel ball 7 to tend to abut against the shoulder 9. This structure is simple and has a good check valve effect.

[0023] A check seat 10 is provided inside the oil outlet channel 5. One end of the spring 8 abuts against the steel ball 7, and the other end of the spring 8 abuts against a step on the outer wall of the check seat 10. The check seat 10 has a blind hole 101 that connects to the connecting seat 6, and the check seat 10 also has a small oil outlet hole 102 that extends radially through the blind hole 101. The check seat 10 partially extends into the spring 8, which facilitates the positioning of the spring 8. Moreover, the blind hole 101 and the small oil outlet hole 102 facilitate precise oil delivery.

[0024] The air intake channel includes an air intake hole 11, one end of which is connected to an air intake connector, and the other end of which is threaded with a plug. The outer wall of the connector 41 has an annular groove 12, and the connector 41 also has a radial hole 13 located within the annular groove 12 and extending radially through it. The connecting seat 6 has a connecting hole 14 extending radially through and connected to the radial hole 13. The housing 1 also has an air intake through hole 15 connecting the air intake hole 11 to each annular groove 12. Gas enters through the air intake hole 11, passes sequentially through the air intake through hole 15, the annular groove 12, the radial hole 13, and the connecting hole 14, and then enters the connecting seat 6, where it mixes with the lubricating oil entering the connecting seat 6 to form a mixed oil-gas mixture. In actual manufacturing, an air intake chamber is formed between the outer wall of the connecting seat 6 and the radial hole 13. The radial hole 13, the air intake chamber, and the connecting hole 14 are interconnected, and the air intake chamber ensures smooth air intake and sufficient air volume. In this embodiment, there are four radial holes 13 that are evenly distributed circumferentially, and two connecting holes 14 that are symmetrically arranged.

[0025] The regulating mechanism includes a valve stem 16 threadedly connected to the housing 1. The lower end of the valve stem 16 has a conical outer wall 161, and the inner wall of the air inlet 15 has a sealing step 17 for sealing the conical surface 161. By rotating the valve stem 16, the opening between the conical surface 161 and the sealing step 17 is changed, thereby adjusting the air intake flow from the air inlet 15 to the annular groove 12, which is convenient for adjustment.

[0026] The upper end of the valve stem 16 extends out of the housing 1, and a locking nut 18 is threadedly connected to the upper end of the valve stem 16. After adjusting the air intake flow, rotating the locking nut 18 causes it to abut against the housing 1, thereby locking the valve stem 16 and preventing it from rotating, thus ensuring good operational stability.
