Detailed description of the preferred embodiments
The present invention will be further described with reference to the accompanying drawings. A water inlet device for a toilet bowl, characterized in that: the water-saving valve comprises a valve body 1, wherein a valve seat 2 is sleeved in the valve body 1 in a hollow manner, a water diversion part 3 is arranged in the valve seat 2, a sealing ring 4 is arranged in the water diversion part 3, and a water inlet channel 31 and a water outlet channel 32 which penetrate through the water diversion part 3 are communicated with the valve body 1 and the valve seat 2; the sealing ring 4 is covered with a sealing ring 5, the sealing ring 5 is sleeved on the valve core 52 and covers the sealing ring 4, the top of the valve body 1 is sleeved with a valve cover 6, the sealing ring 5 seals a gap between the valve cover 6 and the water distributing part 3, and a balance cavity 7 is formed between the valve cover 6 and the sealing ring 5; a lever 8 is hinged on the valve cover 6, one end of the lever 8 is connected with a floater 9, and the other end of the lever 8 is provided with a sealing sheet 81 which can be separately covered on a balance hole 61 at the top of the valve cover 6; the sealing ring 5 is provided with a water guide hole 51, and the water guide hole 51 is communicated with the water diversion member 3 and the balance cavity 7.
The bottom of the valve core 52 is provided with a connecting seat 53, and the inside of the sealing ring 5 is provided with a mounting hole 54 which is sleeved on the connecting seat 53 and forms relative sealing.
The top of the valve core 52 is provided with a guide rod 55, and the guide rod 55 is telescopically sleeved in a guide cylinder 62 at the bottom of the valve cover 6.
The valve cover 6 is installed at the upper end of the valve body 1 in a buckling mode, a water sealing ring 63 is arranged between the valve cover and the valve body, and the water sealing ring 63 seals a gap between the valve cover and the valve body.
The working principle is as follows: when the water level in the water tank is low, the floater moves downwards to lift the lever, so that the sealing sheet at the other end of the lever is forced to be opened on the balance hole 61 at the top of the valve cover 6, water from a tap water net moves upwards through the water inlet pipe at the bottom of the valve seat, tap water penetrates through the water inlet channel 31 in the water distribution piece 3 to enter the valve seat and lift the sealing ring upwards to force the sealing ring to leave the sealing ring, and the water flows back to the valve body through the water outlet channel 32 at the bottom of the sealing ring and is discharged into the water tank through the water discharge channel. In the water inlet process, tap water enters the balance cavity 7 through the water guide hole 51 arranged on the sealing ring, and at the moment, the balance cavity is communicated with the atmosphere through the balance hole 61, so that the internal pressure and the external pressure of the balance cavity 7 are balanced, and water flow can break the sealing ring to open the sealing ring for water inlet.
When the water level reaches a set value, the floater rises to push the lever, the sealing sheet on the lever is used for closing the balance hole, the inflow water in the balance cavity cannot be discharged, the water pressure in the balance cavity gradually rises, the water pressure reversely pushes the sealing ring to move downwards, and the sealing ring is used for sealing the sealing ring to stop the inflow water. Because the pressure area of the balance cavity is far larger than the area of the sealing ring, the water pressure in the balance cavity is enough to press the sealing ring and seal the sealing ring according to the Pascal principle, and the purpose of stopping water entering is realized.
When the user flushes water, the floater descends, the balance hole is opened again, the water in the balance cavity is decompressed, the pressure in the balance cavity is smaller than the pressure of tap water, and the tap water flushes the sealing ring again to enter water, so that the water circulates back and forth.
Compared with the prior art, the structure in the scheme utilizes the phenomenon that the compressed tap water closes the water inlet, the higher the pressure of a tap water pipe network is, the higher the sealing pressure is, and the stronger the sealing performance is, so that the phenomena of leakage and the like caused by overlarge pressure of the tap water pipe network can be avoided. Meanwhile, the sealing speed in the balance cavity is high, and the closed pressure can be generated quickly, so that compared with the traditional floating ball type water inlet valve, the structure has the advantages of shorter closing time, higher speed, reduction in water inlet time of the water inlet valve, high pressure resistance, long service life and the like, and can be widely popularized and used.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
