Reference numerals: 1. a pipe body; 2. a connecting flange; 21. a ring groove; 3. a flange valve; 4. a filter assembly; 41. a mounting ring; 411. an annular groove; 42. a metal filter screen; 5. a shock absorbing assembly; 51. a rubber ring; 52. a rubber gasket; 6. a gasket is provided.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): a filtering pipe fitting with a cleaning and filtering function is shown in figure 1 and comprises a pipe body 1 and connecting flanges 2 which are integrally arranged at two ends of the pipe body 1 respectively. The connection method at the two ends of the pipe body 1 is respectively connected with the flange valve 3 through bolts and nuts, and a sealing gasket 6 is required to be arranged between the connecting flange 2 and the flange valve 3 so as to ensure the connection sealing performance.

As shown in fig. 1 and 2, a ring groove 21 is formed at the inner ring folding angle of each of the two connecting flanges 2, and the filter assemblies 4 are respectively arranged in the ring grooves 21. The filter assembly 4 includes a mounting ring 41 embedded in the ring groove 21, and a metal filter net 42 disposed at a central portion of the mounting ring 41. And the middle parts of the two metal filter screens 42 are all arranged towards the same direction in a concave manner, and the concave surfaces of the metal filter screens 42 are in the water flow impact direction. Meanwhile, along the water flow impact direction, the aperture of the former metal filter 42 is larger than that of the latter metal filter 42. While the part of the metal screen 42 protruding towards the flange valve 3 does not extend into the flange valve 3.

As shown in fig. 1 and 2, a damper assembly 5 for preventing the mounting ring 41 from loosening is provided between the mounting ring 41 and the flange valve 3. The circumferential side of the mounting ring 41 is provided with an annular groove 411, and the damper assembly 5 comprises a rubber ring 51 embedded in the annular groove 411 and tightly abutted between the mounting ring 41 and the inner wall of the annular groove 21, and a rubber gasket 52 tightly abutted between the flange valve 3 and the mounting ring 41.
