Description

Technical Field

[0001] This utility model relates to the field of oil-gas separation technology, specifically to a periodic maintenance filter element for gas-liquid separation. Background Technology

[0002] A hydraulic retarder is an auxiliary braking device that utilizes hydraulic braking. During braking, an oil-gas mixture is discharged from the float valve above the working chamber. This oil-gas mixture will eventually be discharged into the external space through the retarder's exhaust port. If this mixture is not separated, oil mist will accumulate in the retarder housing and certain parts of the vehicle. Areas where oil mist accumulates will attract a large amount of dust and dirt, affecting future vehicle maintenance; in severe cases, it may cause the fluid level inside the retarder to drop, resulting in reduced braking force.

[0003] Currently, this oil mist is mainly removed through labyrinth oil separators and filter elements. The oil mist cannot flow back in time within the labyrinth oil separator; as the retarder continuously brakes, the oil mist accumulates into droplets within the separator, and the oil-gas mixture discharged from the float valve sprays out the accumulated oil mist. The filter element oil removal method is effective when the filter element is not yet saturated. As the retarder continues to brake, the filter element tends to become saturated and can no longer effectively adsorb oil mist. Furthermore, the oil mist already adsorbed within the filter element cannot flow back in time and will be discharged to the outside along with the oil-gas mixture discharged from the float valve. Summary of the Invention

[0016] The limiting groove is located between the exhaust port and the valve body opening.

[0035] The specific content of this utility model will be further explained in detail below with reference to the embodiments. Detailed Implementation

[0036] Unless otherwise specified, all components in this invention are made from components known in the prior art.

[0037] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0038] Example 1:

[0039] This embodiment provides a periodic maintenance filter element for gas-liquid separation, such as... Figures 1-3 As shown, it includes a valve body 1 and filter material arranged inside the valve body. The valve body 1 is a hollow cylinder. An exhaust port 2 is provided on the side wall of the valve body 1. A labyrinth deceleration mechanism 3 is installed at one end of the valve body 1. A movable bottom cover 4 is covered at the end of the labyrinth deceleration mechanism 3 away from the valve body 1. An oil-gas mixture inlet 5 is provided on the bottom cover 4.

[0040] The periodic maintenance filter element for gas-liquid separation also includes a compression device 6 installed at the end of the valve body 1 away from the labyrinth deceleration mechanism 3.

[0041] The compression device 6 includes a compression cover 6-1 and an oil discharge linkage rod 6-2 installed on one side of the compression cover 6-1, with the oil discharge linkage rod 6-2 facing the oil-gas mixture inlet 5.

[0042] After the mechanism has been working for a certain period of time, the filter material inside the valve body 1 will become saturated, and its performance in filtering oil-gas mixtures will decrease. At this time, the user can apply pressure to the compression device 6. Under the action of force, the compression cover 6-1 moves downward, compressing the filter material. The oil in the filter material flows out after compression. During the downward movement of the compression cover 6-1, it drives the oil discharge linkage rod 6-2 to move downward, opening the bottom cover 4 and discharging the oil.

[0043] This utility model provides a periodic maintenance filter element for gas-liquid separation. It uses a compression device to compress the filter material in the valve body, causing the filter material to discharge oil and maintaining good oil removal effect. This avoids the problem that the filter element will become saturated when the retarder is continuously braking, and will no longer be able to effectively adsorb oil mist. In addition, the oil mist adsorbed in the filter element cannot flow back in time and will be discharged to the outside along with the oil-gas mixture discharged by the float valve.

[0044] As a preferred embodiment:

[0045] An oil drain plate 7 is also installed between the valve body 1 and the labyrinth deceleration mechanism 3. The oil drain plate 7 is in the shape of an inverted cone and has an oil drain and vent hole 8 in the center so that the oil can be discharged smoothly from the oil drain plate 7.

[0046] The oil drain linkage rod 6-2 can pass through the oil drain and vent hole 8.

[0047] As a preferred embodiment:

[0048] The filter material inside the valve body 1 is arranged between the oil drain plate 7 and the compression cover 6-1, and the labyrinth deceleration mechanism 3 is installed between the oil drain plate 7 and the bottom cover 4.

[0049] As a preferred embodiment:

[0050] The aforementioned periodic maintenance filter element for gas-liquid separation also includes a limiting mechanism 9.

[0051] The limiting mechanism 9 includes a limiting steel ball 9-1 installed on the side of the compression cover 6-1, and the limiting steel ball 9-1 is connected to the compression cover 6-1 by a spring.

[0052] The limiting mechanism 9 also includes a limiting groove 9-2 formed on the inner wall of the valve body 1, and the limiting steel ball 9-1 cooperates with the limiting groove 9-2.

[0053] The limiting groove 9-2 is located between the exhaust port 2 and the opening end of the valve body 1.

[0054] As a preferred embodiment:

[0055] The exhaust port 2 is strip-shaped and is opened circumferentially along the side wall of the valve body 1.

[0056] The oil-gas mixture inlet 5 is located at the edge of the bottom cover 4.

[0057] The bottom cover 4 is provided with magnetic material on the side facing the valve body 1, which attracts to the end of the valve body 1.

[0058] As a preferred embodiment:

[0059] like Figure 4 As shown, the periodic maintenance filter element for gas-liquid separation also includes a maintenance tool 10.

[0060] The maintenance tool 10 includes a pressure plate 10-1 and a pressure rod 10-2 installed on one side of the pressure plate 10-1.

[0061] The pressure plate 10-1 is also equipped with magnetic material, and the pressure plate is adsorbed onto the compression cover 6-1.

[0062] The specific working process of this utility model:

[0063] When the retarder is working, the oil-gas mixture enters the labyrinth deceleration mechanism 3 through the oil-gas mixture inlet 5 and is decelerated. A portion of the oil mist is separated in the labyrinth deceleration mechanism 3 after deceleration, while the remaining oil-gas mixture enters the valve body 1, is absorbed and filtered by the filter material inside the valve body 1, and is then discharged through the exhaust port 2.

[0064] After the mechanism has been working for a certain period of time, the filter material inside valve body 1 will become saturated, reducing its performance in filtering oil-gas mixtures. At this time, the user can use maintenance tool 10 to compress the compression device 6. The compression cover 6-1 will then move downwards under force, compressing the filter material. The oil in the filter material inside valve body 1 will be discharged through the filter material into the labyrinth deceleration mechanism 3. During its downward movement, the compression cover 6-1 will drive the oil discharge linkage rod 6-2 downwards, opening the bottom cover 4 and discharging the oil. Then, the maintenance tool 10 will be lifted, and the compression cover 6-1 will move upwards under magnetic force. A "click" sound indicates that the limit steel ball 9-1 has engaged in the limit groove 9-2, the filter element maintenance is complete, and the device is back in working condition. In actual operation, the compression cover 6-1 can be pushed and pulled up and down multiple times to ensure effectiveness.

[0065] The above technical solutions are only preferred embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be conceived by those skilled in the art without creative effort within the technical scope disclosed in this utility model are covered within the protection scope of this utility model.
