Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, a butterfly valve with a filtering function comprises a butterfly valve main body 1, a push rod 5 and a fixture block 7, wherein a rotating ring 2 is meshed with the surface of the butterfly valve main body 1 in a threaded manner, an embedding rod 3 is connected to the surface of the rotating ring 2 in a sliding manner, a push plate 4 driving the push rod 5 to slide is fixedly connected to the tail of the embedding rod 3, and a stress plate 6 driving the fixture block 7 to stretch and retract inside the butterfly valve main body 1 is attached to the side surface of the push rod 5.

Further, the inside laminating of butterfly valve main part 1 has filter 8, filter 8's surface is provided with through-hole 12, and filter 8's surface is provided with filtration pore 9, filter 8's surperficial swivelling joint has regulating plate 10, and regulating plate 10's surface is provided with screw hole 11, the side that screw hole 11 is located regulating plate 10 is provided with spout 14 on the surface, and spout 14's inside sliding connection has slide bar 13, slide bar 13's afterbody fixedly connected with and filter 8 sliding connection's movable rod 15.

Furthermore, the contact surface of the stress plate 6 and the push rod 5 is an inclined surface, and the stress plate 6 drives the fixture block 7 to form a sliding structure in the butterfly valve main body 1 through the push rod 5. The binding face of the stress plate 6 and the push rod 5 is an inclined plane, and when the push rod 5 slides, the clamping block 7 can be driven to move downwards, so that the water pipe is fixed.

Furthermore, three groups of fixture blocks 7 are symmetrically arranged around the center of circle of the butterfly valve main body 1, and the three groups of fixture blocks 7 are all perpendicular to the butterfly valve main body 1. Through the setting of three fixture blocks 7, can further strengthen the fixity ability of butterfly valve main part 1 and water pipe.

Furthermore, the through hole 12 is disposed at the center of the adjusting plate 10, and the size of the through hole 12 is the same as the size of the filtering hole 9. Since the size of the through-holes 12 is identical to that of the filter holes 9, the adjusting plate 10 does not affect the use of the filter holes 9.

Furthermore, the sliding groove 14 is obliquely arranged on the surface of the adjusting plate 10, and the sliding rod 13 drives the movable rod 15 through the adjusting plate 10 to form a telescopic structure. Because the sliding groove 14 on the adjusting plate 10 is arranged obliquely, when the adjusting plate rotates, thrust can be applied to the sliding rod 13, so that the sliding rod can push the movable rod 15 to slide outwards, and then the movable rod 15 can be attached to the inner wall of the butterfly valve main body 1, so that the filter plate 8 can be installed.

Furthermore, the diameter of the filter plate 8 is consistent with the diameter of the inner hole of the butterfly valve main body 1, so that the outer wall of the filter plate 8 is fully attached to the inner wall of the butterfly valve main body 1.

The working principle is as follows: when the butterfly valve is used, firstly, the filter plate 8 is installed, the filter plate 8 is placed inside the butterfly valve main body 1, then, the adjusting plate 10 is rotated, as the sliding groove 14 on the adjusting plate 10 is obliquely arranged, when the butterfly valve is rotated, thrust can be applied to the sliding rod 13 to enable the sliding rod to push the movable rod 15 to slide outwards, then, the movable rod 15 can be attached to the inner wall of the butterfly valve main body 1 to install the filter plate 8, finally, a screw is screwed into the threaded hole 11 to fix the adjusting plate 10, and when the butterfly valve is used, as the size of the through hole 12 is consistent with that of the filter hole 9, the adjusting plate 10 cannot affect the use of the filter hole 9;

in order to prevent that butterfly valve main part 1 from droing from the water pipe, steerable rotatory ring 2 is rotatory, because rotatory ring 2 is connected for thread engagement with butterfly valve main part 1's outer wall, can drive push pedal 4 and push rod 5 to atress board 6 removal through embedding pole 3 when it is rotatory, because atress board 6 is the inclined plane with push rod 5's binding face, when push rod 5 slides, can drive fixture block 7 downstream, the realization is fixed to the water pipe, prevent that butterfly valve main part 1 from droing from the water pipe, also be convenient for dismantle butterfly valve main part 1 simultaneously.
