Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in the attached figure 1, the drainage valve convenient for replacing the filter element comprises a valve body 1, wherein a water service pipe 11 is arranged on the inner side of the valve body 1, an outlet on the water service pipe 11 is communicated with a water outlet pipe 2 arranged on one side of the valve body 1, an inlet on the water service pipe 11 is communicated with a water inlet pipe 3 arranged on the other side of the valve body 1, when the valve body 1 starts to drain water, water flows into the water service pipe 11 from the water inlet pipe 3, and water flowing into the water service pipe 11 is discharged from the water outlet pipe 2.

As shown in fig. 1 to 3, a filter frame 17 is provided in the water pipe 11, a plurality of filter elements 18 are provided on the filter frame 17, the number of the filter elements 18 is preferably 4, and the filter elements 18 are communicated with the water outlet pipe 2 and the water inlet pipe 3, so that when water flows into the water pipe 11 from the water inlet pipe 3, the water is discharged from the water outlet pipe 2 through the filter elements 18 in sequence, thereby filtering impurities contained in the water. The filter frame 17 is connected with a fixing plate 14, the fixing plate 14 is nested with a through hole 13 formed in the bottom of the water through pipe 11, the fixing plate 14 is matched with the through hole 13, and the fixing plate 14 performs a sealing function on the water through pipe 11 in the process that water in the water through pipe 11 flows to the water outlet pipe 2, so that the water through pipe 11 is prevented from leaking.

As shown in fig. 1-3, the bottom of the fixing plate 14 is welded to a mounting plate 15 disposed in the valve body 1, two sides of the mounting plate 15 are respectively provided with an inwardly recessed clamping groove a2, the clamping groove a2 is respectively nested with a clamping block a1 disposed in the valve body 1, and the clamping block a1 fixes the mounting plate 15, so that the mounting plate 15 is fixed at the lower end of the inner side of the valve body 1, and the filter frame 17 is fixed in the water pipe 11 disposed in the valve body 1. One side of the fixture block A1 is connected with a limiting plate A3, one side of the limiting plate A3 is welded with a moving rod A5, the moving rod A5 penetrates through mounting holes A6 formed in two sides of the valve body 1, the diameter of the mounting hole A6 is larger than that of the limiting plate A3, in the moving process of the moving rod A5, a limiting plate A3 limits the moving rod A5 to prevent the moving rod A5 from being separated from the mounting hole A6, one end of the moving rod A5 penetrating through the mounting hole A6 is provided with a second limiting plate A7, the diameter of the second limiting plate A7 is larger than that of the mounting hole A6, in the process of enabling the moving rod A5 to be inward, the second limiting plate A7 acts on the moving rod A5 to prevent the moving rod A5 from being separated from the mounting hole A6. The moving rod A5 is nested with a spring A4, one side of the limiting plate A3 connected with the moving rod A5 is welded with one end of a spring A4 arranged in the valve body 1, and the other end of the spring A4 is welded with the inner wall of the valve body 1 close to the mounting hole A6.

Referring to fig. 1 to 3, when the valve body 1 starts to discharge water, water flows from the water inlet pipe 3 to the water pipe 11, and then the water sequentially flows through the filter element 18 to be discharged from the water outlet pipe 2, and in the process that the water sequentially flows to the filter element 18, the filter element 18 filters impurities in the water, after the valve body 1 discharges the water for a period of time, when the filter element 18 needs to be cleaned, the second limiting plate a7 can be used to pull the moving rod a5, so that the moving rod a5 moves outwards under the action of the second limiting plate a7, the moving rod a5 drives the fixture block a1 to move synchronously in the outwards moving process, and the spring a4 is squeezed, so that the fixture block a1 is separated from the fixture groove a2, the mounting plate 15 is not fixed at the lower end of the inner side of the valve body 1, and then is drawn out from the bottom of the valve body 1 downwards from the valve mounting plate 15, the mounting plate 15 drives the bottom of the valve body 1 to, the filter element 18 on the filter frame 17 can be cleaned to prevent the filter element 18 from being blocked.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
