when the scheme is put into practical use, the friction force is further increased through the anti-slip pad, so that the hand can conveniently hold the poking shaft 19 to push the first fixing ring 13 or the second fixing ring 25 to rotate.
Working principle: when the intelligent valve body 4 is installed, two ports of the intelligent valve body 4 are respectively in butt joint with the first butt joint pipe 1 and the second butt joint pipe 5, after the butt joint is finished, a plurality of groups of locking bolts 2 penetrate through the joint, and the other end of the intelligent valve body is in spiral connection with the locking bolts 2 through a fixing nut 3 to achieve the effect of sealing connection;
when the lock bolt 2 is installed, the first butt joint ring 6 and the second butt joint ring 31 are rotatably sleeved on the flange at the bottom of the intelligent valve body 4 from the outside, the first butt joint ring 6 and the second butt joint ring 31 are fixed into a complete circular ring by rotating the first locking rod 9, the first connecting ring 14 and the second connecting ring 21 are sleeved on the flange at the top of the first butt joint pipe 1 in the same way and then fixed by the second locking rod 22, the fixed screw cap 3 is placed into the butt joint port 7 and sequentially placed into each butt joint port 7, the fixed screw cap 3 pushes the first limiting block 18 from the top of the butt joint port 7 to compress the first spring 17 to slide towards the inside of the sliding groove 16, after the fixed screw cap 3 is completely placed into the butt joint port 7, the bulge at one side of the first limiting block 18 is buckled on the upper end face of the fixed screw cap 3 under the elastic force of the first spring 17, so that the fixed screw cap 3 is fixed inside the butt joint port 7, after the locking bolts 2 pass through the supporting seat 15 through the synchronous tightening assembly to enable the threaded ends to pass through and be in spiral connection with the butt joint openings 7, the first fixing ring 13 and the second fixing ring 25 are rotationally sleeved on the top flange of the first butt joint pipe 1, the rotation angle of the connecting gears 24 is adjusted to enable each connecting gear 24 to be meshed with the first fixing ring 13 or the second fixing ring 25, then the locking bolts 2 are tightly screwed and fixed through the third locking rods 26, each locking bolt 2 is inserted into the corresponding fixing frame 23 to be rotationally connected with the fixing nuts 3, then the first fixing ring 13 or the second fixing ring 25 can be rotated, the connecting gears 24 are driven to rotate on the second connecting ring 21 or the first connecting ring 14 in a meshed mode, a plurality of locking bolts 2 can be synchronously in spiral connection with the fixing nuts 3, after all the locking bolts 2 are in spiral connection with the fixing nuts 3, because each lock bolt 2 needs to be manually screwed with the fixing nut 3 before, a certain deviation can be caused to the degree of the subsequent screw connection between the lock bolt 2 and the fixing nut 3 due to the rotation of the connecting gear 24, when the lock bolt 2 cannot be continuously screwed down by the rotation of the first fixing ring 13 or the second fixing ring 25, the problem that the connection between the single lock bolt 2 and the fixing nut 3 is not tight enough still can exist, at the moment, the third locking rod 26 is opened and rotated to open the first fixing ring 13 and the second fixing ring 25, one end of the inserting shaft 20 is inserted into the slot 28 on the fixing frame 23, the locking bolt 2 and the fixing nut 3 are further tightly connected by manually stirring the inserting shaft 20, and all the fixing frames 23 are tightly detected by the inserting shaft 20 in sequence, so that the tight connection between all the lock bolts 2 and the fixing nuts 3 is realized.
