The present invention will be further described with reference to the accompanying drawings. A reverse sealing closestool water inlet valve is characterized in that: the water outlet device comprises a water outlet seat 1 and a water inlet seat 2 sleeved in the water outlet seat, wherein a water outlet hole 3 is formed in the center of the bottom of the water inlet seat 2, a sealing seat 4 extending upwards is arranged on the water outlet hole 3, a sealing ring 6 is arranged on the sealing seat 4 through a pressure plate 5, a gland 7 covers the top of the water outlet seat 1, the periphery of the sealing ring 6 seals the gland 7 with the water outlet seat 1 and a gap between the gland 7 and the water inlet seat 2, and the middle part of the sealing ring 6 covers the upper end of the sealing seat 4 and seals the upper end face of the sealing seat 4; the bottom of the water inlet seat 2 is eccentrically provided with a water inlet 8, and the bottom of the water inlet 8 is connected with a water inlet pipe 9 connected with a tap water pipeline;
the sealing ring 6 is provided with a balance hole 61 penetrating through the upper end surface and the lower end surface of the sealing ring, the pressure plate 5 is provided with a drainage column 51 penetrating in the balance hole 61, and the drainage column 51 is communicated with a water inlet 8 and a pressure bin 62 of the sealing ring 6 and a gland 7;
the gland 7 on articulated the installing drive lever 10, drive lever 10 one end is connected with float 11, the other end is provided with sealed mouth 12 and presses on the pressure release hole 13 on gland 7, float 11 lift process drive sealed mouth 12 and pressure release hole 13 butt joint or separation.
The lower end of the water outlet hole 3 is connected with a water outlet pipe 14, and an opening of the water outlet pipe 14 is positioned on the side wall of the water outlet pipe 14, so that the outlet water is sprayed towards the side wall of the water outlet pipe 14.
The top of pressure disk 5 be provided with in last guide post 15 extends into the last guide hole 16 in gland 7, the bottom of pressure disk 5 is provided with down guide post 17, down guide post 17 extends into apopore 3.
The water inlet seat 2 is internally provided with a water retaining ring 18, the inner hole of the water retaining ring 18 is clamped outside the sealing seat 4, the outer circle of the water retaining ring is clamped on the inner hole of the water inlet seat 2, and the water retaining ring is provided with a plurality of water guide holes 19.
The drainage groove 52 is arranged in the drainage column 51, and the drainage groove 52 penetrates through the upper end and the lower end of the pressure plate 5.
The diameter of the sealing ring 6 is larger than that of the water outlet hole 3.
The working principle is as follows: as shown in the water flow direction sketch map in fig. 5, when the water level is lower in the water tank, float 11 sinks, the float lifts the sealing nozzle through the drive lever swing, make sealing nozzle and pressure release hole separation, make the pressure release hole opened, at this moment, the water that is located pressure reservoir 62 flows from the pressure release hole play, and the running water that gets into from oral siphon 9 has certain pressure, water is provided with drainage post 51 entering pressure reservoir 62 under the effect of pressure on balance hole and the pressure disk 5 that sets up from sealing washer 6, because pressure reservoir has been lasted the pressure release, come from the water pressure in the oral siphon upwards jack-up the sealing washer, thereby make the sealing washer open apopore 3, the apopore switches on with the oral siphon, the purpose of intaking has been realized.
When the water level of the water tank rises to a set position, the floater floats upwards, and the floater swings through the driving rod to press the sealing nozzle downwards, so that the sealing nozzle is in butt joint with the pressure relief hole, and the pressure relief hole is closed. After the pressure relief hole is closed, the water flow from the tap water pipe network continues to enter the pressure chamber 62 through the balance hole arranged on the sealing ring 6 and the diversion column 51 arranged on the pressure plate 5, and as the pressure chamber is sealed, the water pressure is gradually increased along with the increase of the water amount, the water in the pressure chamber is forced to downwards push the sealing ring, so that the sealing ring downwards moves to press on the water outlet hole 3, the water outlet hole is closed, and the purpose of stopping water inflow is achieved. Wherein, because the diameter of sealing washer is big, and is greater than the diameter of apopore far away, according to pascal's principle, the pressure in pressure storehouse is enough to close the apopore.
Compared with the prior art, the reverse stopping mode of blocking the water outlet hole is adopted in the scheme, so that the water inlet valve in the scheme is closed, the larger the pressure of the water network is, the larger the water pressure in the pressure bin is, the larger the pressure applied to the sealing ring is, the larger the pressure of the sealing water outlet hole is, the better the sealing performance is, the pressure resistance value is improved, the use in the environment with higher water pressure is suitable, and the application range of the water inlet valve is expanded. In addition, the water inlet in the scheme is eccentrically arranged on the water inlet seat, so that the water inlet and the water outlet are staggered, and the water outlet is positioned at the central position of the water inlet seat, thereby facilitating the matching of accessories such as a pressure plate, a sealing ring and the like, ensuring that the layout of the sealing structure is more compact and efficient, and being widely popularized and used.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
