The first water stop assembly 2 and the second water stop assembly 3 are both arranged on the valve body 1: the first pontoon 4 is connected with the first water stopping assembly to control the opening/closing of the water inlet passage 11. The second pontoon 5 is connected with the water stop assembly to control the second water stop assembly to open/close the water inlet channel 11, and the second pontoon 5 is positioned above the first pontoon 4. In an embodiment, the second buoy 5 is provided with a guide hole. The second pontoon 5 is located directly above the first pontoon 4. The screw rod of the first buoy 4 passes through the guide hole and then is in butt joint with the first water stop assembly 2, so that the structure is compact. When the first water stop component 2 fails or leaks, the first water stop component 2 cannot close water inflow, and in a continuous water inflow state, the water level rises to the position of the second pontoon 5, and the second pontoon 5 floats upwards, so that the second water stop component is driven to block the water inflow channel 11, and water cut-off is realized.
In an embodiment, the valve body 1 is provided with a first mounting opening 13 and a second mounting opening 14 for mounting the first water stop assembly 2 and the second water stop assembly 3, respectively.
The first mounting opening 13 is provided with a water inlet 131 and a water outlet 132. The second mounting opening 14 is provided with a water inlet 141 and a water outlet 142. The water inlet 131 of the first mounting opening 13 is in butt joint with the water inlet channel 11 of the valve body 1, the water inlet 141 of the second mounting opening 14 is communicated with the water outlet 132 of the first mounting opening 13, and the water outlet 142 is communicated with the water outlet channel 12 of the valve body 1. The first water stop assembly 2 opens/closes the water inlet 131. The second water stopping assembly opens/closes the water outlet 142.
In this embodiment, the first mounting opening 13 and the second mounting opening 14 are different mounting openings, and in other embodiments, the first mounting opening 13 and the second mounting opening 14 may be set to be the same mounting opening according to the actual requirement and the mounting space.
The water inlet 131 and the water outlet 132 of the first mounting opening 13 are coaxially arranged, and the water outlet 132 surrounds the water inlet 131. The first water stop assembly 2 comprises a blocking piece 21, an end cover 22 and a swinging piece 23. The blocking piece 21 is installed at the positions of the water inlet 131 and the water outlet 132. The blocking piece 21 is movably installed or adopts an elastic piece, and is provided with a water passing hole, which is communicated with/cuts off the water inlet 131 and the water outlet 132. The end cover 22 covers the first mounting opening 13 and forms a pressure relief cavity, and the end cover 22 is provided with a pressure relief hole 221. The swing piece 23 is movably arranged on the end cover 22 or the valve body 1. The first pontoon 4 is connected to swing the swing part 23 to open/close the pressure release hole 221. In this embodiment, the blocking piece 21 is an elastic piece, and is mounted at the bottom of the first mounting hole 13. The end cap 22 presses the peripheral portion of the blocking piece 21, and is provided with a guide rod penetrating the water passing hole.
When in use, when the water level rises, the first pontoon 4 floats upwards and drives the swinging part 23 to block the pressure relief hole 221. The water in the water inlet channel 11 enters the pressure release cavity through the water passing holes of the plugging sheet 21, and the plugging sheet 21 compresses the water inlet 131 and the water outlet 132 under the action of water pressure. When the water level drops, the first pontoon 4 is lowered and drives the swing piece 23 to open the pressure relief hole 221, water in the pressure relief cavity is discharged through the pressure relief hole 221, the pressure on the plugging sheet 21 is relieved, and the plugging sheet 21 is flushed by the water of the water inlet 131, so that the communication between the water inlet 131 and the water outlet 132 is realized.
The second water stop assembly 3 comprises a plug 31, a connecting piece 32 and a lifting rod 33. The plug 31 is movably installed and is close to the water outlet 142. The bottom end of the lifting rod 33 is mounted on the second buoy 5, the top end of the lifting rod extends into the water outlet channel 12 of the valve body 1 and is connected with one end of the connecting piece 32, and the other end of the connecting piece 32 penetrates through the water outlet hole 142 and is connected with the plug 31 to seal/open the water outlet hole 142. In this embodiment, the water outlet 142 is upward and is coaxially disposed with the water outlet 12 of the valve body 1, and the water outlet 12 of the valve body 1 surrounds the water outlet 142. The lower part of the water outlet channel 12 of the valve body 1 is provided with a contraction, and a perforation is arranged at the contraction position. The lifting rod 33 enters the water outlet channel 12 through the perforation and extends upwards to the position of the water outlet hole 142. In order to improve the stability of the second water stop assembly 3, at least two of the lifting rods 33 are uniformly distributed on the periphery of the water outlet 142 and are connected at the top. The connecting piece 32 is a connecting rod, or in other embodiments, the connecting rod is a pull rope, and the plug 31 is a metal block, which can be lowered by its own weight. In this embodiment, the top surface of the plug 31 is conical, and in other embodiments, a spherical surface, a plane surface, a semi-arc surface, etc. may be used.
When in use, when the first water stop component 2 fails, the water level is continuously raised, so that the second buoy 5 floats upwards and drives the lifting rod 33 to move upwards, and the plug 31 is pulled upwards through the connecting piece 32, so that the water outlet hole 142 is blocked, and the water stop effect is realized. When the water level drops, the second pontoon 5 and the lifting rod 33 drop, the plug 31 is driven to move downwards by the connecting member 32, or the plug 31 drops under the action of gravity, and the water outlet 142 is opened again.
In order to avoid the water backflow, in one embodiment, a check member 15, such as a check valve, may be disposed between the water inlet 141 and the water outlet 142 of the second mounting port 14, and in other embodiments, a filter may be disposed.
In the normal water inlet process of the water valve provided by the utility model, referring to fig. 7 and 8, both the blocking piece 21 and the plug 31 are in an open state, and the water flow route is shown in the figure. When the water in the water tank reaches the preset height, and under the condition that the first water stop component 2 fails, the second water stop component 3 serving as a standby can start and block the waterway, so that the problem of continuous water inflow of the toilet water tank is avoided, and the waste of water is also avoided, as shown in fig. 9.
While the utility model has been described above with reference to the accompanying drawings, it will be apparent that the utility model is not limited to the above embodiments, but is capable of being modified or applied directly to other applications without modification, as long as various insubstantial modifications of the method concept and technical solution of the utility model are adopted, all within the scope of the utility model.
