Referring to fig. 1-9, a method for using a valve with energy saving effect includes the following steps:

step one, when the valve needs to be opened, the manual control assembly is rotated anticlockwise to drive the two threaded columns 36 and the rotating shaft 35 to rotate anticlockwise, the two mounting blocks 34 can be driven to be away from each other due to the threaded action of the threaded columns 36 and the threaded hole sleeves 37, at the moment, the torque clutch control assembly 4 at the threaded hole sleeves 37 can lock the mounting blocks 34 and the threaded hole sleeves 37, the mounting blocks 34 and the threaded hole sleeves 37 do not rotate relatively, the two gate plates 22 are driven to be retracted into the corresponding gate grooves 21 through the connecting rods 33 and the control rods 32, water passes through the water through holes, in the process, the right end of the smooth flow guide sleeve 52 is blocked by the left side of the gate plate 22, the V-shaped elastic sheet 43 in the torque clutch control assembly 4 at the transmission sleeve 68 deforms and is separated from the corresponding clamping groove, the torque clutch control assembly 4 at the transmission sleeve 68 does not transmit torque, the transmission sleeve 68 and the worm gear 66 rotates relatively, and the smooth flow guide sleeve 52 keeps still;

it should be emphasized that, when the smooth flow guiding sleeve 52 is blocked by the left side of the gate plate 22 in this step, the friction force between the right end of the smooth flow guiding sleeve 52 and the left side of the gate plate 22 does not cause the torque clutch control assembly 4 at the position of the screw hole sleeve 37 to lose the effect of transmitting torque, that is, when the friction force exists between the right end of the smooth flow guiding sleeve 52 and the left side of the gate plate 22, the threaded column 36 can still generate a threaded movement effect with the screw hole sleeve 37 when rotating, and the mounting block 34 and the screw hole sleeve 37 cannot rotate relatively.

Step two, continuing to rotate the manual control assembly anticlockwise, at the moment, the flashboard 22 is completely retracted into the gate slot 21 and can not move continuously, the flashboard 22 can not block the smooth flow guide sleeve 52 from moving right, the V-shaped elastic sheet 43 in the torque force clutch control assembly 4 on the screw hole sleeve 37 deforms and is separated from the corresponding slot, the torque force clutch control assembly 4 at the screw hole sleeve 37 can not transmit torque force, the threaded column 36 and the screw hole sleeve 37 rotate together relative to the mounting block 34, the threaded column 36 and the rotating shaft 35 rotate, but the mounting block 34 can not move any more, at the moment, the smooth flow guide sleeve 52 is driven to move right through the transmission of the flow guide sleeve control assembly 6, the torque force clutch control assembly 4 at the transmission sleeve 68 transmits torque force, the worm wheel 66 rotates along with the transmission sleeve 68 and the transmission shaft 65, and the right end of the smooth flow guide sleeve 52 is connected with the connection annular slot 53, so that water flow from the water hole is stable;

step three, when the valve needs to be closed, the manual control assembly is rotated clockwise, the two mounting blocks 34 can be driven to approach each other, the smooth guide sleeve 52 blocks the two gate plates 22 from approaching each other, at the moment, the V-shaped elastic sheet 43 in the torque clutch control assembly 4 on the screw hole sleeve 37 deforms and is separated from the corresponding clamping groove, the torque clutch control assembly 4 at the screw hole sleeve 37 does not transmit torque, the threaded column 36 and the screw hole sleeve 37 rotate together relative to the mounting blocks 34, the torque clutch control assembly 4 at the transmission sleeve 68 transmits torque due to the transmission of the guide sleeve control assembly 6, the worm wheel 66 rotates along with the transmission sleeve 68 and the transmission shaft 65, and the guide sleeve 52 moves leftwards and retracts into the sliding annular groove 51;

in this step, the friction between the outer side of the smooth flow guiding sleeve 52 and the two gate plates 22 does not cause the torque clutch control assembly 4 at the position of the transmission sleeve 68 to lose the function of transmitting torque, i.e. when the outer side of the smooth flow guiding sleeve 52 and the two gate plates 22 generate friction, the worm wheel 66 can still rotate along with the transmission sleeve 68 and the transmission shaft 65, so as to ensure that the smooth flow guiding sleeve 52 is normally retracted into the sliding annular groove 51;

fourthly, the guide sleeve 52 is completely retracted into the sliding annular groove 51, the two gate plates 22 are not blocked by the guide sleeve 52, the manual control assembly continues to rotate clockwise, at the moment, the V-shaped elastic sheet 43 in the torque clutch control assembly 4 at the position of the transmission sleeve 68 deforms and is separated from the corresponding clamping groove, the torque clutch control assembly 4 at the position of the transmission sleeve 68 does not transmit torque, the worm wheel 66 cannot rotate along with the rotation of the transmission sleeve 68 and the transmission shaft 65, the torque clutch control assembly 4 at the position of the screw hole sleeve 37 transmits torque, the torque clutch control assembly 4 at the position of the screw hole sleeve 37 can lock the mounting block 34 and the screw hole sleeve 37, the mounting block 34 and the screw hole sleeve 37 do not rotate relatively, and due to the thread effect of the screw hole sleeve 37 and the threaded column 36, the two gate plates 22 approach each other and finally block the water through holes, and cut off the running water of the water through holes;

step five, water in the middle connecting pipeline 14 flows back after being blocked in the water through holes to form a water hammer effect, the water flowing back in the middle connecting pipeline 14 pushes the conical control ring 75, the eliminating sleeve 71 moves leftwards against the elastic force of the first spring 76, and the conical control ring 75 moves leftwards to reduce the water hammer effect through the buffering of the first spring 76;

sixthly, the elimination sleeve 71 moves leftwards to enable the water inlet 81 to be aligned to the water inlet end of the C-shaped diversion channel 82, the water outlet 83 is aligned to the water outlet end of the C-shaped diversion channel 82, the drainage plate 84 loses the shielding of the elimination sleeve 71, the torsion spring 86 drives the drainage plate 84 to extend out of the water inlet 81, backflow water is blocked and buffered, and the water hammer effect is further reduced;

step seven, simultaneously introducing the reflowing water into the C-shaped flow guide channel 82, impacting the water hammer eliminating and buffering assembly 9 by the water in the C-shaped flow guide channel 82, and reducing the water hammer effect by using the buffering of the water hammer eliminating and buffering assembly 9;

step eight, water enters the elimination sleeve 71 from the water outlet end of the C-shaped diversion channel 82 and the water outlet 83 and offsets with the water reflowing in the elimination sleeve 71 to reduce the flow velocity of the reflowing water.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art.
