When the electromagnetic valve is not needed, the rotating rod 35 outside the water pipe 21 can be manually rotated, the gear at the other end of the rotating rod 35 is driven to rotate through the rotating rod 35, and due to the fact that the gear 36 is completely matched with the thread on the limiting rod 38, the gear 36 can drive the limiting rod 38 to move towards the valve block 24 in the rotating process until the limiting rod 38 is inserted into the limiting hole 39. Before the electromagnetic valve is used, the rotating rod 35 can be rotated in the opposite direction, the rotating rod 35 drives the gear 36 to rotate in the opposite direction, so that the limiting rod 38 is driven to move in the direction away from the valve block 24, the limiting rod 38 is pulled out of the limiting hole 39, and then the electromagnetic valve can be started.
The working principle is as follows: firstly, the filter plate 28 is installed in the water pipe 21, the filter plate cover 31 is opened, the filter plate 28 is placed into the water pipe 21 from the fourth through hole 30, the second spring 29 is contacted with the inner wall of the water pipe 21, then the filter plate cover 31 is covered, the second spring 29 is compressed in the process, the filter plate 28 is fixed inside the water pipe 21, then fluid flows into the water pipe 21, the fluid firstly reaches the filter plate 28 at the water inlet end, and the fluid flows through the filter plate 28 to achieve the filtering effect.
When the electromagnetic valve is used, the coil 5 is connected with the binding post 11 of the sliding rheostat 8 through a wire, the binding post 11 is additionally connected with a wire leading to the outside of the electromagnetic valve, the wire is firstly connected with a power supply, namely the coil is electrified, electromagnetic force is generated in the coil 5 after the coil is electrified, the electromagnetic force attracts the valve core 22 to move upwards, the valve core 22 drives the valve block 24 to move upwards, the valve core 22 is connected with the valve block 24 through the soft partition layer 23, and the soft partition layer 23 is fixedly arranged in the connecting pipe 20, so that the soft partition layer 23 can deform but cannot change in position in the moving process of the valve core 22 and the valve block 24, when the valve block 24 does not move upwards, the solid cylindrical part at the upper part of the valve block 24 abuts against the notch of the stop block 27 to close a water flow channel, so that fluid cannot pass through, the second through hole 25 is formed at the lower part of the valve block 24, during the movement process, the uncovered part of the second through hole 25 gradually increases, the fluid flows to the water outlet end through the second through hole 25, when the electromagnetic force is balanced with the gravity of the valve core 22 and the valve block 24 and the elastic force of the first spring 26, the valve core 22 and the valve block 24 will not move any more, and at this time, the flow rate of the electromagnetic valve is fixed.
If the flow of the electromagnetic valve is to be controlled, the motor 19 is firstly turned on, the screw 17 is driven to rotate by the motor 19, and the moving rod 14 and the screw 17 are in threaded connection, so that in the rotation process of the screw 17, the moving rod 14 horizontally moves along the threads, and the sliding sheet 13 is driven to move left and right on the support rod 12, so that the resistance value of the sliding rheostat 8 is changed, the resistance value is changed, the current in the coil 5 is changed, the electromagnetic force of the coil 5 is changed, the electromagnetic force on the valve core 22 is changed, the valve core 22 and the valve block 24 move in the vertical direction, and the size of the unblocked part of the second through hole 25 is changed, namely the flow of the electromagnetic valve is changed, and when the forces on the valve core 22 and the valve block 24 are balanced, the flow of the electromagnetic valve is stable and unchanged.
When the electromagnetic valve is not needed, the power supply is cut off, the electromagnetic force in the coil 5 disappears, the valve core 22 and the valve block 24 are not acted by the electromagnetic force, the valve block 24 and the valve core 22 fall downwards due to the existence of gravity all the time, and the valve block 24 is located at a certain fixed height in the water pipe 21 after the valve block 24 is balanced by the force due to the connection of the first spring 26 below the valve block 24.
In order to prevent the valve block 24 from being moved by external force when the electromagnetic valve is closed, the rotating rod 35 outside the water pipe 21 is manually rotated, the gear at the other end of the rotating rod 35 is driven to rotate by the rotating rod 35, and because the gear 36 is completely matched with the thread on the limiting rod 38, the gear 36 can drive the limiting rod 38 to move towards the valve block 24 in the rotating process until the limiting rod 38 is inserted into the limiting hole 39 to fix the position of the valve block 24. When the electromagnetic valve needs to be used, the rotating rod 35 is rotated in the opposite direction, the rotating rod 35 drives the gear 36 to rotate in the opposite direction, so that the limiting rod 38 is driven to move in the direction away from the valve block 24, the limiting rod 38 is pulled out from the limiting hole 39, and then the electromagnetic valve can be started.
After long-term use, a large amount of impurities exist on the surface of the filter plate 28, the filter plate 28 needs to be cleaned, the filter plate cover 31 is firstly opened, the second spring 29 is not stressed to restore the original state, the filter plate 28 is popped out from the fourth through hole 30, then the filter plate 28 is manually taken out, and then the filter plate 28 is cleaned.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
