[0020] like Figure 1-Figure 2As shown, a kind of corrosion-resistant valve filter, comprising: filter housing 101, installation groove 102 on filter housing 101, fluid passage 103 through opening on filter housing 101 and installation groove 102, water inlet port 104 and water outlet port 105 on filter housing 101 and matched with fluid passage 103, installation ring table 106 between water inlet port 104 and water outlet port 105, filter basket 107 on installation ring table 106, and quick fixing device for quickly fixing filter basket 107 between filter basket 107 and upper cover.

[0021] In order to facilitate quick installation of upper cover and disassembly of filter basket 107, the quick fixing device comprises: abutment ring table 108 on filter basket 107 for abutting with installation ring table 106, sleeve ring 109 on upper cover matched with installation groove 102, first connecting thread (not shown in the figure) on the outside of sleeve ring 109, second connecting thread (not shown in the figure) on installation groove 102 matched with first connecting thread, and compression device between sleeve ring 109 and abutment ring table 108 for compressing filter basket 107 after locking upper cover.

[0022] In order to facilitate quick positioning and compression of filter basket 107, the compression device comprises: positioning groove 110 on the inside of sleeve ring 109, rotating bearing 111 on positioning groove 110, abutment ring plate 112 on the inner ring of rotating bearing 111 and abutting on the upper end, the abutment ring plate 112 is provided with inclined groove 113 matched with filter basket 107, and the abutment ring plate 112 is further provided with inflow device for fluid inflow.

[0023] The abutment ring plate 112 is further provided with a rounded corner 114 for preventing damage to filter basket 107.

[0024] In order to facilitate quick installation of abutment ring plate 112, the installation groove 102 is further provided with guiding device for facilitating user to quickly install upper cover, the guiding device comprises: guiding block (not shown in the figure) on installation groove 102, guiding groove 115 on abutment ring plate 112, first bevel 116 on guiding groove 115, and second bevel (not shown in the figure) on guiding block.

[0025] In order to facilitate fluid inflow into filter basket 107, the inflow device comprises: slot 117 on abutment ring plate 112 matched with fluid passage 103 and water inlet port 104.

[0026] In order to facilitate movement of filter and disassembly of upper cover, the upper cover is further provided with handle 118 for facilitating movement of valve filter and screwing of upper cover.

[0027] In order to enhance the sealing, prevent the unfiltered impurities flow into the water outlet port 105, the mounting ring table 106 and the resistance ring table 108 are provided with a sealing ring 119 for preventing fluid from passing through the gap.

[0028] In order to prolong the service time of the filter basket 107 and prevent it from corrosion, the filter basket 107 is a stainless steel filter basket 107.

[0029] In order to facilitate the connection with the water conveying pipe, the water inlet port 104 and the water outlet port 105 are further provided with a connecting flange 120 for facilitating the connection of the conveying pipe.

[0030] Working principle: when assembling, the sealing ring 119 is prevented on the mounting ring table 106, and then the filter basket 107 is placed on the mounting ring table 106, and then the resistance ring plate 112 on the upper cover is aligned with the filter basket 107, and then the installation can be started. During the installation process, the resistance ring plate 112 is gradually aligned with the resistance ring plate 112 under the action of the guide block, the guide groove 115 and the rotating bearing 111, while preventing it from rotating, and then the user twists the upper cover to lock it on the mounting groove 102. At this time, under the action of the rotating bearing 111, the resistance ring plate 112 descends with the locking of the upper cover until it abuts against the resistance ring table 108, completing the positioning of the filter basket 107. When using, the fluid flows from the water inlet port 104, then flows into the filter basket 107 through the slot 117, and then filters through the filter basket 107, and then flows to the water outlet port 105. After a long time of use, the user directly twists off the upper cover, which can drive the resistance ring plate 112 to move upward, releasing the positioning of the filter basket 107, and completing the disassembly of the filter basket 107.
