DETAILED DESCRIPTION

[0019] A valve comprises a square frame 101 and two flow pipes 102 fixedly connected to the left and right sides of the square frame 101, wherein the two flow pipes 102 are slidably fitted on the left and right surfaces of a disc valve 201, and an arc seat 103 is fixedly connected to the bottom and the front and rear sides of the square frame 101 respectively, and the three arc seats 103 are respectively embedded and rotatably connected to the lower half of the disc valve 201 along the circumferential direction, and the surface of the disc valve 201 is evenly rotatably connected with three flow ports, and any flow port can be aligned between the two flow pipes 102 to allow the medium to circulate.

[0020] This part is based on Figure 1-4The working process expressed in 8 and 9 is: to facilitate the provision of a circular valve that can be rotated and adjusted at the flow opening of the pipeline, so that any flow opening on the circular valve can be aligned with the inside of the pipeline for circulating medium, so that any flow opening on the disc valve can be regularly cleaned. When in use, the two flow pipes 102 are fixedly installed on the left and right sides of the square frame 101, and the two sides of the two flow pipes 102 are connected to the pipeline for circulating medium. Synchronously, the disc valve 201 is connected to three arc seats 103 arranged along the circumferential direction through its outer side. When the disc valve 201 rotates by relying on the three arc seats 103, any flow opening on the disc valve 201 can be aligned with the middle flow position of the flow pipes 102 on both sides for circulating medium, so that the circular valve can be rotated and adjusted at the flow opening of the pipeline, so that any flow opening on the circular valve can be aligned with the inside of the pipeline for circulating medium. When blocking the flow, the disc valve 201 can be rotated so that there is no flow opening to block the flow medium between the two flow pipes 102. The structure is simple and easy to use.

[0021] The bottom rear flow port of the disc valve 201 is fixedly connected with a sieve plate 202 , and a plurality of small holes are evenly arranged on the sieve plate 202 .

[0022] This part is based on Figure 1-4 The working process expressed in 8 and 9 is: when the disc valve 201 is rotated so that the sieve plate 202 located on the flow port at the bottom rear side of the disc valve 201 is aligned with the flow medium between the two flow pipes 102, the sieve plate 202 in the flow port can use multiple small holes to filter larger particles of impurities from the flowing medium, making the flowing medium clearer and cleaner, thereby improving the working diversity of the disc valve 201 after rotating to adjust the flow port.

[0023] Two convex walls are respectively disposed on both side surfaces of the disc valve 201 , and the inner sides of the two convex walls on the same side are respectively slidably fitted on the outer side surface of one of the flow tubes 102 .

[0024] This part is based on Figure 1-4 The working process expressed in 8 and 9 is: two convex walls are respectively provided on the two side surfaces of the disc valve 201, and the inner sides of the two convex walls on the same side slide and fit on the outer surface of the flow tube 102 on that side, so that the disc valve 201 can be more stably rotated to limit the flow tube 102 through the convex walls to prevent the flow tube 102 from position displacement.

[0025] A circular seat 203 is fixedly connected to the flow port at the front side of the bottom of the disc valve 201 , and a plurality of blades 204 are evenly fixedly connected to the circular seat 203 along the circumferential direction.

[0026] Each of the blades 204 has sharp surfaces on both sides.

[0027] This part is based on Figure 1-4 The working process expressed in 8 and 9 is: after the disc valve 201 is rotated and adjusted so that the flow port on the front side of the bottom of the disc valve 201 is aligned with the two flow pipes 102 for circulating the medium, in order to improve the fluidity of the circulating medium and prevent blockage, when in use, the blades 204 with sharp surfaces on both sides can be arranged on the circular seat 203 along the circumferential direction. When the medium is circulating, the sharp surface of each blade 204 can be aligned with the circulating medium. When the medium is circulating, the larger impurities inside are shredded by inertia when passing through the sharp surfaces of multiple blades 204 due to the high-speed circulation, so that the medium circulation is more efficient and the fluidity of the medium passing through the disc valve 201 is improved.

[0028] The bottom of the square frame 101 is fixedly connected to the base 104, the bottom of the base 104 is rotatably connected to the bottom rod 301, the left side of the bottom rod 301 is fixedly connected to the pulley I302, the left middle part of the disc valve 201 is fixedly connected to the convex rod 205, the convex rod 205 is fixedly connected to the pulley II304, and the pulley I302 and the pulley II304 are connected through a belt 303.

[0029] This part is based on Figure 1-5 The working process expressed in 8 and 9 is: when adjusting the rotation angle of the disc valve 201, the output shaft of a first motor is fixedly connected to the right side of the bottom rod 301 through a coupling, and the first motor is fixedly connected to the base 104 through bolts. The first motor is driven to rotate the bottom rod 301, and then the pulley I302 and the pulley II304 rotate synchronously under the drive of the belt 303, and then the pulley II304 can drive the protruding rod 205 to rotate, and the rotation angle of the disc valve 201 is adjusted synchronously, so as to facilitate the operation of any flow port of the disc valve 201 to circulate the medium.

[0030] The outer sides of the two flow pipes 102 are respectively fixedly connected with docking seats.

[0031] This part is based on Figure 1-5 The working process expressed in 8 and 9 is: each flow tube 102 is fixedly connected to a docking seat on the outside, so as to facilitate docking with pipelines for circulating other circulating media through the docking seat.

[0032] The top of the square frame 101 is rotatably connected to a threaded rod 105, and the front and rear sides of the threaded rod 105 are respectively connected to a sliding seat 401 in a transmission manner. The middle parts of the two sliding seats 401 are respectively slidably connected to the front and rear sides of the top of the square frame 101, and the tops of the two sliding seats 401 are respectively fixedly connected to a semicircular frame plate 402, and the two semicircular frame plates 402 are arranged in a mirror image.

[0033] The threads on the front and rear sides of the threaded rod 105 are arranged in opposite directions.

[0034] This part is based on Figure 1-9 The working process expressed in the figure is: in order to facilitate the hanging setting of the disc valve 201, so as to facilitate the corresponding temporary hanging pipeline to flow the medium, when in use, the output shaft of a second motor is fixedly connected to the rear side of the threaded rod 105 through a coupling, and the second motor is fixedly connected to the top rear side of the square frame 101 through bolts, and the second motor is driven to rotate the threaded rod 105. When the threaded rod 105 rotates, the two sliding seats 401 move towards each other through the feature that the threads on both sides rotate in opposite directions, and then the semicircular frame plates 4 on the upper sides of the two sliding seats 401 are rotated. 02 Clamp the upper beam or fixed object so that the square frame 101 is hung in the upper position, and the two circulation pipes 102 are synchronously suspended in the upper position, and the pipelines connected to the two circulation pipes 102 are synchronously in the upper position to prevent the circulation pipes from affecting the ground work on the ground, so that the disc valve 201 can be hung and set, so as to facilitate the circulation of the medium in the corresponding temporary hanging pipe. The two semi-cylindrical semi-circular frame plates 402 can improve the clamping work of objects of different widths and specifications, and improve the adaptability of the overall structure.

[0035] A rotating rod 403 is rotatably connected to the middle of each semicircular frame plate 402, and a pulling wheel 404 is fixedly connected to the middle of each rotating rod 403. Each pulling wheel 404 is evenly provided with a plurality of grooves along the circumferential direction.

[0036] This part is based on Figure 1-9 The working process expressed therein is: in order to facilitate the square frame 101 to move laterally when the two semicircular frame plates 402 clamp the beams or fixed objects, thereby preventing the staff from having to reinstall the work steps, when in use, an output shaft of a third motor is fixedly connected to the top of each rotating rod 403 through a coupling, and the two third motors are driven to rotate each rotating rod 403. When each rotating rod 403 rotates, the pulling wheel 404 located in the middle of each rotating rod 403 rotates synchronously. When each pulling wheel 404 rotates, it can move in contact with the object clamped by the two semicircular frame plates 402, so that the square frame 101 at the bottom of the two semicircular frame plates 402 moves laterally synchronously. A plurality of grooves are evenly arranged along the circumferential direction on each pulling wheel 404, so as to increase the friction between the clamped object and improve the efficiency of the movement of the entire device.
