The working principle of the invention is that when people want to control the flow speed of the clean water, the double-eccentric butterfly valve which is convenient to open and close and has high sealing performance can be used, firstly, a user pushes the connecting mechanism 6 outwards and backwards, then the user connects the main body frame 1 between two water pipes, then the user loosens the connecting mechanism 6, the connecting mechanism 6 fixes the water pipes, then the user introduces the clean water into the water pipes, the clean water flows into the main body frame 1 through the water inlet 2, the rotating sealing plate 4 blocks the clean water, so that the clean water can not flow, the user can rotate the rotating mechanism 5 according to the actual situation, the rotating mechanism 5 drives the rotating sealing plate 4 to rotate, so that the rotating sealing plate 4 opens the channel of the main body frame 1, the clean water flows into the water outlet 3 through the main body frame 1, the clean water flows into the other water pipe through the water outlet 3, thereby controlling the flow speed of the clean water, after the flow of clear water is completed, the user loosens the rotating mechanism 5, so that the rotating mechanism 5 drives the rotating sealing plate 4 to reversely rotate to the recovery position, and the rotating sealing plate 4 closes the channel of the main body frame 1.
After the user inserts the water pipe with water inlet 2 and delivery port 3, the user rotates rotary rod 52, rotary rod 52 drives rotary seal plate 4 and rotates, torsion spring 55 twists reverse deformation, make rotary seal plate 4 open main part frame 1 passageway, the clear water flows into in main part frame 1 through water inlet 2, the clear water flows into in delivery port 3 through water inlet 2 again, the clear water flows into in another water pipe through delivery port 3, the user can be according to actual conditions, and refer to numerical value on the instruction disk 54, thereby control the velocity of flow to clear water, the clear water flows the completion back, the user loosens rotary rod 52, torsion spring 55 resets, thereby drive rotary rod 52 and rotary seal plate 4 antiport and resume the normal position, make rotary seal plate 4 close main part frame 1 passageway.
The user connects ring 62 to the pulling of outside dorsad, connect ring 62 and drive inserted bar 63 to the motion of outside dorsad, first reset spring 64 is stretched, the user inserts main body frame 1 afterwards among two water pipes, main body frame 1 and water pipe contact back, the user loosens and connects ring 62, first reset spring 64 resets, thereby drive and connect ring 62 and inserted bar 63 to the inside side motion, inserted bar 63 is to the inside side motion after inserting the water pipe, make inserted bar 63 fix on the water pipe, prevent that main body frame 1 from taking place the skew and dropping.
The user rotates the half frame 74 of location, the half frame 74 of location drives swivelling joint board 73 and rotates, second reset spring 75 is stretched, swivelling joint board 73 rotates to contact the back with stopper 72, the user stops to rotate the half frame 74 of location, the user is in with main body frame 1 access two water pipes afterwards, the half frame 74 of location is loosened to the user then, second reset spring 75 resets, thereby drive swivelling joint board 73 and the half frame 74 antiport of location, swivelling joint board 73 antiport breaks away from stopper 72, the half frame 74 antiport of location arrives with the water pipe after, the half frame 74 of location presss from both sides tightly the water pipe, thereby prevent that main body frame 1 from taking place to become flexible.
When the rotary connecting plate 73 rotates, the rotary connecting plate 73 drives the upper connecting frame 81 to rotate, the upper connecting frame 81 drives the narrow connecting plate 82 to move inwards, the third return spring 85 is stretched, the narrow connecting plate 82 drives the hollow connecting frame 83 to move inwards, the hollow connecting frame 83 drives the lower connecting frame 84 to move inwards, the lower connecting frame 84 drives the connecting ring 62 and the inserting rod 63 to move inwards, the first return spring 64 is stretched, after a user connects the main body frame 1 into two water pipes, when the rotary connecting plate 73 rotates reversely, the third return spring 85 is reset, so that the upper connecting frame 81 and the narrow connecting plate 82 are driven to move outwards and backwards, the first return spring 64 is reset, so that the connecting ring 62 and the inserting rod 63 are driven to move outwards and backwards, the connecting ring 62 drives the hollow connecting frame 83, the lower connecting frame 84, the upper connecting frame 81, the third return spring 85 and the narrow connecting plate 82 to move outwards and backwards, after the insertion rod 63 moves outwards and backwards to be inserted into the water pipe, the insertion rod 63 fixes the water pipe.
When the rotary sealing plate 4 rotates, the rotary sealing plate 4 rotates to cooperate with the shovel-shaped ring 92 in a contact manner, thereby driving the right movement, the shovel-shaped ring 92 drives the sealing ring 91 to move rightwards, the sealing ring 91 drives the slider 93 to move rightwards, the slider 93 drives the thin limiting rod 94 to move rightwards, the fourth reset spring 95 is stretched, the shovel-shaped ring 92 cleans impurities left over the water outlet 3, simultaneously, the main body frame 1 and the water pipe are sealed, when the rotary sealing plate 4 rotates reversely, the rotary sealing plate 4 rotates reversely to separate from the shovel-shaped ring 92, the fourth reset spring 95 resets, thereby driving the slider 93, the thin limiting rod 94, the shovel-shaped ring 92 and the sealing ring 91 move leftwards to the recovery original position.
The user upwards extracts bolt 104, bolt 104 breaks away from slide 51, activity inserted block 101 and fixed block 103 back, the user rotates activity inserted block 101, make activity inserted block 101 break away from fixed block 103, the user rotates rotary rod 52 again, rotary rod 52 rotates to after contacting with fixed block 103, user's antiport activity inserted block 101, activity inserted block 101 antiport reaches after contacting with fixed block 103, the user inserts slide 51 with bolt 104 again, in activity inserted block 101 and the fixed block 103, make activity inserted block 101 and fixed block 103 fix rotary rod 52, alleviate user's work load to a certain extent.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
