Technical Field

[0002] A butterfly valve, also known as a flap valve, is a regulating valve with a simple structure. It can be used for the on-off control of low-pressure pipeline media. A butterfly valve refers to a valve whose closing part (valve disc or butterfly plate) is a disc, which rotates around the valve axis to achieve opening and closing. Wear-resistant and corrosion-resistant butterfly valve is a valve specially designed for corrosive and abrasive media. It has excellent wear resistance and corrosion resistance. This butterfly valve is mainly composed of valve body, valve seat, valve stem, valve disc (butterfly plate) and other components. These components are usually made of corrosion-resistant and wear-resistant materials, such as stainless steel, alloy steel, fluoroplastics, etc., to ensure long-term use in corrosive media without damage.

[0038] More specifically, in the embodiment of the present invention, an expansion box 708 is installed on the inner wall of the heat preservation box 4, and an expansion cover 709 is installed on the top side of the expansion box 708; a squeezing wheel 710 is rotatably installed on one side of the driving frame 705, and the expansion box 708 expands due to heat, driving the expansion cover 709 to bulge, which is used to squeeze the squeezing wheel 710. It should be noted that in the embodiment of the present invention, when the sunlight intensity is high and the temperature in the heat preservation box 4 is too high, the expansion box 708 expands due to heat, causing the expansion cover 709 to bulge, thereby pushing the squeezing wheel 710 to move, and the squeezing wheel 710 drives the driven unfolding frame 701 to slide through the driving frame 705, thereby achieving the purpose of driving the folding shielding cloth 702 to unfold and shield the light-transmitting plate 8.

[0039] In summary, the working principle of a wear-resistant and corrosion-resistant butterfly valve provided by an embodiment of the present invention is: During the use of the butterfly valve 1, the butterfly valve 1 and the electric controller 2 as well as the connection between the butterfly valve 1 and the two connecting pipes 3 are sealed and protected by two insulation boxes 4 to avoid the problem of long-term exposure to the sun and rain and corrosion; in addition, a light-transmitting plate 8 is installed on the insulation box 4, and the interior of the insulation box 4 is heated by sunlight to achieve the insulation function, thereby ensuring the normal use of the butterfly valve 1 and avoiding freezing; in addition, the windward plate 601 is blown by the outdoor wind, and the windward plate 601 moves to drive the debris removal frame 602 to move, and the debris removal frame 602 moves in the push-pull groove 605 through the push-pull block 604, and the push-pull block 604 slides on the limit slide rod 607 through the push-pull hole 606, and drives the two support springs 608 to be stressed, and the debris removal frame 602 scrapes impurities on the light-transmitting plate 8 through a plurality of scrapers 603 to ensure the light transmission effect of the light-transmitting plate 8; Furthermore, when the intensity of sunlight is high and the temperature in the heat preservation box 4 is too high, the expansion box 708 is heated and expanded, causing the expansion cover 709 to bulge, thereby pushing the extrusion wheel 710 to move, and the extrusion wheel 710 drives the driving frame 705 to rotate, and the driving frame 705 rotates in the reset groove 712 through the connecting shaft 711, and drives the reset torsion spring 713 to be stressed, and the driving frame 705 rotates through the driving shaft 706 to drive the driven unfolding frame 701 to slide, and the driven unfolding frame 701 slides horizontally in the moving slide groove 704 through the moving block 703, and the driven unfolding frame 701 slides and drives the folding shielding cloth 702 to unfold, and the light-transmitting plate 8 is blocked, so as to prevent the sunlight from continuously passing through the light-transmitting plate 8, causing the temperature in the heat preservation box 4 to be too high and damaging the electric controller 2; Furthermore, when using or repairing the butterfly valve 1, the handle 509 is pulled to make the handle 509 slide on the rectangular rod 512, and the contraction spring 513 is stretched. The handle 509 moves downward to drive the two positioning rods 510 to disengage from the two plug-in slots 511, thereby unlocking the handle 509. At this time, the handle 509 is rotated to drive the rotating push rod 506 to rotate through the rectangular rod 512. The rotating push rod 506 drives the two insulation boxes 4 to unfold through the two push-open shafts 507. The insulation boxes 4 slide and unfold in the stretching sleeve 502 through the stretching plate 503, and drive the return spring 504 to stretch, so that the two insulation boxes 4 can be opened synchronously.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
