Description

Technical Field

[0001] The utility model belongs to the technical field of filters applied to pipeline components, and in particular relates to a filter device. Background Art

[0002] The two ends of the existing pipe fittings are connected to the pipes and used to circulate water, playing a connecting role between the two pipes. However, due to the existing water quality problems in some areas, the water quality may not meet the use standards, and a filter is usually required to be installed separately. This will require that after the pipe fittings are installed between the pipes and the pipes, the filter must be installed on the pipes. This is not only troublesome to install, but also troublesome to replace the pipes later. In addition, the occupancy rate is too high and the structure is not compact within the limited space. In particular, the existing pipe fittings are basically two-way straight pipes. Under special working conditions, they cannot be installed, or they are installed through other special-shaped connecting pipe fittings. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a filter device with a compact structure, easy installation and good filtering effect.

[0004] The purpose of the present utility model is achieved through the following technical solution. The filter device includes a pipe body, which is provided with a water inlet end and a water outlet end. The water inlet end and the water outlet end are communicated with the middle cavity of the pipe body. The middle cavity of the pipe body is provided with a filter assembly, and the filter assembly is located between the water inlet end and the water outlet end. The filter assembly is distributed in an oblique shape on the middle cavity of the pipe body, and the axial line of the filter assembly is distributed at an acute angle to the axial line of the water inlet end, and the axial line of the filter assembly is distributed at an obtuse angle to the axial line of the water outlet end.

[0005] The beneficial effects of the present invention are as follows: compared with the prior art, by integrating the filter assembly on the pipe body, the structure of the filter device is more compact and the installation is more convenient; at the same time, the filter assembly is distributed obliquely with the water inlet and the water outlet, so that the water entering the water inlet is filtered by the filter assembly and then flows into the water outlet, and the filtering effect is better. Another advantage of the oblique distribution is that compared with the vertical distribution, it is more convenient to disassemble and assemble when replacing the filter screen in the filter assembly, that is, the space for extracting the filter screen upward can be more compact, and it is convenient to disassemble and assemble within a limited height space.

[0006] Preferably, the filter assembly includes a cylindrical filter screen and a cover body. The filter screen is located in the middle cavity and is limited in the middle cavity by tightening the cover body and the pipe body; and the filter cavity of the filter screen is communicated with the middle cavity, and the side wall of the filter screen is communicated with the water outlet end; through the setting of the above structure, all the water entering the water inlet end can be filtered through the filter screen and then enter the water outlet end, thereby achieving a complete filtration effect.

[0007] Preferably, a circle of protrusions is provided at the upper end of the middle cavity, one end of the filter is limited on the outer circle of the protrusion, the other end of the filter is against the cover body, and the cover body and the pipe body are screwed and fixed by threads; by providing the protrusions, the filter is limited in the middle cavity, especially when the water flow is relatively fast, the filter will not fall out of the middle cavity.

[0008] Preferably, a circle of stepped grooves is provided on the inner side of the cover body, and one end of the filter is limited in the stepped groove. In this way, when installing the filter, the filter can be embedded in the stepped groove in advance, which not only facilitates installation, but also enables the filter to be limited and fixed.

[0009] Preferably, a sealing assembly is provided between the cover body and the pipe body, and the sealing assembly includes a sealing ring, which is embedded in a circle of grooves provided on the end face of the cover body, and when the cover body and the pipe body are tightened, the sealing ring and the end face of the pipe body are abutted; by providing the sealing assembly, the sealing effect between the cover body and the pipe body after tightening is better, thereby ensuring the performance of the product.

[0010] Preferably, the water inlet and the water outlet are located on both sides of the middle cavity, the water inlet and the water outlet are distributed in parallel, and the water inlet is located below the water outlet; through the setting of the above structure, the filtering effect of the filter in the process of filtering impurities is better, that is, the water entering the water inlet can completely flow into the filter, and then flow into the water outlet through the mesh wall of the filter, so that the filtered impurities all fall onto the inner wall of the filter; at the same time, the height difference between the water inlet and the water outlet, especially for some large-scale production equipment, the height difference is basically fixed, and the setting of the above structure can be well applied.

[0011] Preferably, the inner circumferential wall of the water inlet end is provided with an internal thread threadedly connected to the pipe, the outer circumferential wall of the water outlet end is provided with an external thread threadedly connected to the pipe, and a circle of handshake protrusions is provided on the outer circumferential wall of the water outlet end located at the end of the external thread; through the arrangement of the above structure, the disassembly and assembly between the pipe parts and the pipes is more convenient, and the handshake protrusions are provided to facilitate the installation between the pipe parts and the pipes.
