as shown in fig. 1 and 5, the mounting seat 4 and the filter frame 3 are inserted into the mounting groove 41 and contact with the inclined surface at the bottom of the fixing strip 43, so that the fixing strip 43 is forced to slide into the side groove 44, and the fixing strip 43 is finally popped out and clamped into the fixing groove 42 in cooperation with the use of the second spring 45, and the positions of the mounting seat 4 and the filter frame 3 are fixed, and the fixing strip 43 can be manually pulled to be separated from the fixing groove 42, so that the mounting seat 4 and the filter frame 3 can be conveniently detached.
The working principle is as follows: when the flange of the built-in filtering structure is used for connecting a soft seal fixed ball valve, as shown in fig. 1-7, firstly, the handle 23 at the outer side of the liquid leakage seat 2 can be rotated, the sealing plate 26 is driven to slide through the screw 24, the liquid leakage groove 21 is opened and closed, so that pollution discharge and sealing are facilitated, meanwhile, the handle 23 drives the sleeve ring 231 and the guide sheet 232 to rotate, reciprocating rotation of the vibrating rod 234 is realized, the vibrating rod is contacted with the guide groove 233 to generate vibration, and the pollution discharge efficiency is improved;
then, the inside of the filter frame 3 can be filtered through the side filter plate 33, and meanwhile, the fixing strip 43 slides back and forth, so that the filter frame 3 and the mounting seat 4 can be detached, cleaned and mounted, when the control assembly 11 drives the valve rod 12 to rotate, and the valve core 13 is opened and closed, the guide rod 34 and the blocking plate 344 at the bottom of the guide rod can be driven to rotate through the belt 343, the toothed roller 342 and the gear 341, the through groove 46 is closed and opened through the blocking plate 344, the internal sealing and the discharge of impurities and liquid in the filter frame 3 are realized, and the service life of the filter frame 3 is prolonged.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
