[0002] With the continuous progress and development of society, hydraulic systems are increasingly being used in both daily life and industry. The widespread application of hydraulic systems has also driven the rapid development of filters. Filters are generally divided into two main categories: coarse filters and fine filters. Suction filters are a branch of coarse filters. They are typically used in conjunction with hydraulic pumps, installed at the oil outlet of the oil tank, to protect the hydraulic pump and other components from damage caused by impurities and contaminants in the hydraulic fluid, and to prevent larger particulate contaminants from entering the hydraulic system.

[0003] Normally, the oil inlet of the filter is directly connected to the filter element, and there is no valve at the oil inlet. The oil inlet is directly connected to the oil inlet of the filter element, and the oil directly enters the interior of the filter element. There is no valve or valve body to stop the flow. At the same time, the oil in the tank will leak when the filter element is replaced. Utility Model Content

The illustrative embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation of the present invention.

[0015] Figure 1 This is a schematic diagram of the structure of the high-flow self-sealing oil suction pipeline filter of this utility model. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] One embodiment of this application provides a high-flow-rate self-sealing oil suction line filter, such as... Figure 1 As shown, it includes: a filter housing 1 with openings at both ends, the filter housing 1 having a filtration space 11 inside; a media outlet 12 is provided on the filter housing 1, the media outlet being connected to the filtration space 11; Flange cover 2, which is detachably installed at one end of filter housing 1 by bolts; Bottom cover 3 is detachably installed on the other end of filter housing 1 by bolts. The flange cover 2 and bottom cover 3 seal the filter housing 1, which has openings at both ends. The media outlet 12 is located near bottom cover 3. Filter element 4 is installed in the filtration space 11; the structure of filter element 4 is existing technology and will not be described in detail here; there is a preset gap between the outer surface of filter element 4 and the inner wall of filtration space 11 for the outflow of media; one end of filter element 4 is connected to filter housing 1 through connector 5, and the other end of filter element 4 is installed with the inner side of bottom cover 3 to achieve relative fixation of filter element 4; The flange cover 2 is provided with a medium inlet 21, which is connected to the liquid inlet of the filter element 4; It also includes a self-sealing valve assembly 6, which is installed on the filter housing 1 or the flange cover 2 and is located in the filtration space 11; the media inlet 21 is connected to or disconnected from the liquid inlet of the filter element 4 through the self-sealing valve assembly 6.

[0018] Specifically, in one embodiment, such as Figure 1As shown, the self-sealing valve assembly 6 includes a self-sealing valve housing 61, one end of which is mounted on the filter housing 1 or the flange cover 2; one end of the self-sealing valve housing 61 is open, and the other end is closed; the open end of the self-sealing valve housing 61 communicates with the medium inlet 21 of the flange cover 2; at least one liquid outlet hole 62 is provided on the side wall of the self-sealing valve housing 61; a self-sealing guide rod 63 is installed on the closed end of the self-sealing valve housing 61, and a self-sealing valve cover 64 is movably installed on the self-sealing guide rod 63. The self-sealing valve cover 64 is sleeved on the self-sealing valve housing 61, and a self-sealing spring 65 is installed between the self-sealing valve cover 64 and the self-sealing valve housing 61. The self-sealing spring 65 is sleeved on the self-sealing guide rod 63; the side wall of the self-sealing valve cover 64 has an opening for communication with the liquid outlet hole. The through hole 66, which matches the hole 62, allows the outlet hole 62 to communicate with or disconnect from the inlet of the filter element 4 under the action of the self-sealing spring 65. Under normal conditions, the self-sealing valve 64, under the action of the bottom cover 3 and the filter element 4, allows the through hole 66 to communicate with the outlet hole 62, thus enabling the flow of the medium. When the filter element 4 is replaced, the self-sealing spring 65, without the action of the bottom cover 3 and the filter element 4, automatically blocks the outlet hole 62 under the elastic force of the self-sealing spring 65, and the through hole 66 and the outlet hole 62 are no longer connected. The addition of a self-sealing valve assembly at the inlet effectively reduces oil leakage from the tank, thereby saving costs. The self-sealing valve assembly abandons the original manual self-sealing method and upgrades to automatic self-sealing, which not only facilitates user operation but also saves space and reduces maintenance costs.

[0019] In one embodiment, such as Figure 1 As shown, the filter housing 1 is provided with a signaling hole, which is used to install a signaling device 7. When the filter element adsorbs a certain amount of impurities, the signaling device 7 will issue an alarm message to remind the user to replace the filter element. If not, the user may not have replaced the filter element in time. It should be noted that the structure and operation of the signaling device 7 are existing technologies and will not be described in detail here.

[0020] In one embodiment, such as Figure 1 As shown, it also includes a lifting ring 8, which can be detachably installed on the bottom cover 3 to facilitate the handling of the filter and the replacement of the filter element.

[0021] In one embodiment, such as Figure 1 As shown, it also includes a first sealing ring 9, which is installed between the flange cover 2 and the filter housing 1; the flange cover 2 is provided with a first mounting groove for installing the first sealing ring 9.

[0022] In one embodiment, such as Figure 1As shown, it also includes a second sealing ring 10, which is installed between the bottom cover 3 and the filter housing 1; the bottom cover 3 is provided with a second mounting groove for installing the second sealing ring 10.
