in the initial state, the butt valve sleeve 2 is not acted by external force, at this moment, the first force application member 41 is located in the magnetic force cavity 45, the second force application member 42 applies suction force and/or repulsive force to the first force application member 41, and acts on the butt valve sleeve 2 through the pull rod 43 to provide sealing force for sealing the valve port 21 of the butt valve sleeve 2, and as the first force application member 41 and the second force application member 42 are all permanent magnets, constant sealing force can be continuously provided, so that leakage of liquid is not easy to occur after the valve port 21 is sealed, and the first force application member 41 and the second force application member 42 are arranged outside the valve guide cavity 11, so that the first force application member 41 and the second force application member 42 touch water to rust, and can keep magnetic force to provide constant sealing force.
In the valve device, the valve body 8 is not pushed by the top core 3, and at this time, the third urging member 92 applies a sealing force to the valve body 8, so that the valve body 8 and the valve hole member 6 seal and block the water outlet 51.
When the butt joint mechanism is in butt joint with the valve device, the butt joint valve sleeve 2 is firstly abutted against the valve hole piece 6, the conical wall 61 on the inner wall of the valve hole piece 6 is matched with the conical surface 24 on the outer wall of the butt joint valve sleeve 2, meanwhile, the sealing flange 62 on the inner wall of the valve hole piece 6 is matched with the annular groove 25 on the outer wall of the butt joint valve sleeve 2, sealing is firstly carried out when the butt joint mechanism is in butt joint, then the valve body 5 pushes against the butt joint valve sleeve 2 to open the valve port 21, meanwhile, the top core 3 pushes against the valve core 8 to be separated from the valve hole piece 6, at the moment, the liquid level sensor senses liquid in the shell 10, when the magnetic induction piece 31 senses the magnetic force of the fifth force application piece 23, the butt joint mechanism is characterized in that the valve device is in butt joint with the butt joint mechanism, at the moment, the top core 3 keeps pushing against the valve core 8, and the through-flow cross section of the valve hole piece 6 is set to be large, so that when the water storage capacity in the shell 10 is different, the water storage can still continuously output liquid with large flow through the valve device due to gravity of the self, and a smooth flow channel in the valve cavity 11, so that a great flow loss caused by the entropy production area due to boundary layering of flowing liquid is avoided.
During butt joint, the force application component 4 provides a sealing force for driving the butt joint valve sleeve 2 to move towards the direction of the plugging valve port 21, and the valve control component 9 provides a sealing force for driving the valve core 8 to move towards the direction of the valve hole piece 6, so that when the butt joint mechanism is separated from the valve device, the valve core 8 blocks the water outlet 51 under the action of the force application component 4 and the valve control component 9, the valve port 21 is sealed by the butt joint valve port 21, the effect of shutoff is achieved, then the butt joint mechanism is separated from the valve device, and the effect of first shutoff and then separation is achieved.
