Detailed Description

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

Referring to fig. 1-3, an embodiment of the present invention is shown: an industrial hydraulic self-closing butterfly valve comprises a butterfly valve body 1, wherein one side of the butterfly valve body 1 is fixedly connected with a first flange 2, the inner wall of the first flange 2 is provided with a first threaded hole 4, the bottom end of the butterfly valve body 1 is fixedly connected with a positioning frame 6, one side inside the positioning frame 6 is fixedly connected with a limiting spring 7, the other end of the limiting spring 7 is fixedly connected with a limiting block 8, one side, far away from the limiting block 8, inside the positioning frame 6 is provided with a groove, the inner wall of the groove is matched with a second flange 3, the bottom end of the second flange 3 is provided with a limiting hole 9 matched with the limiting block 8, an operator places the second flange 3 in the positioning frame 6, the limiting block 8 and the limiting hole 9 are matched with each other by rotating the second flange 3, the limiting block 8 extrudes the limiting spring 7 to deform, then the operator rotates the second flange 3, after the limiting block 8 and the limiting hole 9 on the second flange 3 are matched with each other, no. two flanges 3 can't be continued to rotate this moment, and at this moment, under the effect of the restoring force of limiting spring 7, limiting spring 7 promotes stopper 8 and agrees with in spacing hole 9 to when improving the operator and assembling flange 2 and No. two flanges 3, because No. two flanges 3 lack the problem that the location leads to No. two flanges 3 constantly rotating in the installation, thereby make things convenient for the operator to install flange 2 and No. two flanges 3.

Further, the outer wall of the first flange 2 is rotatably connected with a waterproof cover 10 through a hinge 15, the waterproof cover 10 is made of transparent acrylic materials, a discoloring layer 13 is fixedly connected to the inner wall of the waterproof cover 10, a water permeable hole 14 is formed in the bottom end of the discoloring layer 13, a waterproof layer is coated on the outer wall of the discoloring layer 13, anhydrous copper sulfate is filled in the discoloring layer 13, a first sealing ring 11 is arranged at one end, close to the first flange 2, of the second flange 3, a second sealing ring 12 is arranged at the contact position of the waterproof cover 10 and the water pipe 5, the waterproof cover 10 and the second sealing ring 12 are arranged in a communicated manner, so that water outside the waterproof cover 10 cannot enter the discoloring layer 13, when water leaks from the joint of the first flange 2 and the second flange 3, leaked water can enter the discoloring layer 13 through the water permeable hole 14, the color of the water discoloring material in the discoloring layer 13 is changed, at the moment, the discoloring layer 13 can remind a worker of the equipment failure, make things convenient for the staff to maintain this equipment, solve the problem that No. 2 flange and No. 3 flange joints leaked.

The working principle is as follows: when an operator installs the device, firstly, the waterproof cover 10 is opened by taking the hinge 15 as a rotation center, then an operator fits the second flange 3 into the positioning frame 6, at the moment, the second flange 3 extrudes the limiting block 8 to move, meanwhile, the limiting block 8 extrudes the limiting spring 7 to deform, then the operator rotates the second flange 3, after the limiting block 8 and the limiting hole 9 on the second flange 3 are mutually fitted, the second flange 3 cannot be continuously rotated, at the moment, under the restoring force action of the limiting spring 7, the limiting spring 7 pushes the limiting block 8 to fit in the limiting hole 9, then the installer can assemble the first flange 2 and the second flange 3 by using bolts, after the installation is finished, the operator rotates the waterproof cover 10 in the reverse direction, so that the waterproof cover 10 rotates by taking the hinge 15 as the rotation center and is closed, at the moment, outside water cannot enter the inner wall of the waterproof cover 10, when the condition of leaking takes place for a flange 2 and No. two flange 3 junctions, the water of a flange 2 and No. two flange 3 junctions seepage gets into discoloration layer 13 through hole 14 that permeates water, makes the anhydrous copper sulfate in discoloration layer 13 take place the colour change, and at this moment, will become blue anhydrous copper sulfate in discoloration layer 13 and can remind this equipment trouble of staff, makes things convenient for the staff to maintain this equipment, solves the problem that a flange 2 and No. two flange 3 junctions leaked.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
