Embodiment 1

[0021] In this embodiment, a flange surface 3 is provided on the outer periphery of the cylinder body 1 , and a plurality of through holes are provided on the flange surface 3 in the circumferential direction. In this way, during installation, the pressure valve can be fixedly installed through the through holes on the flange surface 3 through bolts.

[0022] In this embodiment, one side of the flange surface 3 is covered with a gasket to improve the sealing performance between the outer circumference of the cylinder 1 and the surrounding structures when the cylinder 1 is installed.

Embodiment 2

[0024] In this embodiment, the cylinder body 1 is composed of a plurality of cylinder sections 1-1, and the cylinder sections 1-1 are of a structure with opposite ends, and the two ends of the cylinder section 1 are respectively provided with matching internal threads 5 and external threads. In this way, the adjacent cylinder sections 1-1 are sealed and connected through the internal thread 5 and the external thread, which ensures the tightness of the butt joint between the cylinder sections 1-1 and ensures the easy disassembly of the cylinder body 1 . The multi-layer elastic pads 2 correspond to the multi-section barrel sections 1-1 one by one, and each elastic pad 2 is installed inside the corresponding barrel section 1-1 and is located on the side of the internal thread 5 inside the barrel section 1-1 close to the external thread 4. In this way, in this implementation, a single cylinder section 1-1 can be replaced by disassembling the cylinder section 1-1, thereby reducing t...

Embodiment 3

[0026] This embodiment is a combination of Embodiment 2 and Embodiment 3. Specifically, in this embodiment, the flange surface 3 is arranged on the outer circumference of one of the cylindrical sections 1-1.

Abstract

The invention discloses a pressure valve for an air filter. The pressure valve comprises a cylinder and multi-layer elastic pads. The cylinder is of a two-end opposite through structure. The multi-layer elastic pads are stacked in the cylinder, and the elastic pads are in sealed connection with the inner wall of the cylinder in the circumferential direction. The elastic pads are provided with a plurality of filter holes with the hole diameter increased along with stretching of the elastic pads, and the filter holes are closed when the elastic pads are in a natural state. The provided pressurevalve for the air filter is simple in structure, installation and replacement are convenient, and the application range is wide. In the pressure valve for the air filter, fluid convection is achievedthrough the filter holes in the elastic pads, and the filter holes can be used for filtering pollutants in the fluid.

Description

technical field [0001] The invention relates to the technical field of filters and pressure valves, in particular to a pressure valve for an air filter. Background technique [0002] As a universal filter tool, the filter has a wide range of applications, such as oil filter systems, air filter systems, etc. Existing filters, especially when used in a circulating flow environment, are designed with a bypass circuit in order to avoid the blockage of the filter element causing the circulation channel to be cut off. [0003] The existing bypass circuits are implemented by electric signal control valves, and some use pressure valves, but these bypass valves are all complex in structure, unable to filter the fluid, and have a single function. Contents of the invention [0004] Based on the technical problems in the background technology, the present invention proposes a pressure valve for an air filter. [0005] The present invention proposes a pressure valve for an air filter...
