Abstract
The utility model discloses a water inlet valve used on a cistern of a toilet, which comprises a valve body, a valve core, a connecting rod and a float ball. The utility model is characterized in that a baffle plate is arranged in the valve body, the valve core penetrates through the baffle plate, the upper end of the valve core is hinged in the middle the connecting rod, and the lower end of the valve core is provided with a convex head. The water inlet valve of a cistern has good sealing performance along with the rise of water pressure, and meanwhile, the utility model also has the advantages of long service life, easy enforcement and high practical value.
Description
The utility model relates to the water intaking valve that uses on a kind of toilet tank.
Common tank intake valve of water is to cause after adopting the water tank middle water level to raise that ball float rises, then by the connecting rod that links to each other with ball float make rubber stopper push down water inlet and automatically control intake.The water intaking valve of this structure, in actual use, often owing to misplace etc. former between rubber stopper hardening deforming or rubber stopper and the water inlet thereby drainage take place.The low level cistern leakproof water economizer that Chinese patent 88202413.2 provides is on original water tank basis, increased the sealing that two-way bifunctional adjusting parts and the two-sided bounce-back limiting plate of quadrature improve water intaking valve.But,, up to the present be not commercially available its product as yet because this leakproof water economizer architecture advances more complicated is difficult for implementing.
The purpose of this utility model is at the present existing easy seepy question of tank intake valve of water, and a kind of simple in structure, tank intake valve of water that leak preventing effect is desirable is provided.
The purpose of this utility model realizes by following technical proposal: tank intake valve of water comprises spool in the valve body, water inlet pipe, valve body, be hinged on the connecting rod on the valve body and the ball float of connecting rod end.Be provided with baffle plate in the valve body, the inlet opening is arranged in the baffle plate, spool passes the inlet opening, and the upper end of spool is hinged in the middle of the connecting rod, and the lower end of spool is a plush copper.This water intaking valve is similar with common water intaking valve, also is that the water intaking valve switching is controlled in the variation that is caused the ball float position by the height of water tank middle water level.When water tank was anhydrous, ball float was owing to deadweight falls, and the water in the water inlet pipe enters in the water tank by the inlet opening.Along with the rising of water tank middle water level, ball float constantly rises under buoyancy function, and rises together by connecting rod drive spool.After spool rose to certain altitude, the plush copper of spool lower end will rise to the aperture of inlet opening and be pressed on the inlet opening, and water intaking valve is closed, and reached the purpose of control cistern water level.After the discharging of the water in the water tank, along with falling of ball float, spool also falls, and water intaking valve is opened again.
The utility model is because the mode of utilizing the plush copper of spool to seal the inlet opening is controlled closing of water intaking valve, so hydraulic pressure is high more, sealing performance is good more on the contrary, and is just opposite with existing structure.Simultaneously, the position of spool is more fixing, and phenomenons such as dislocation can not take place, so the stable performance of this water intaking valve, long service life.Compare with existing tank intake valve of water, the manufacturing process and the material therefor of this water intaking valve are very nearly the same, and historical facts or anecdotes is executed easily, and higher utility is arranged.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the schematic diagram of the tank intake valve of water that provides of the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, this tank intake valve of water comprises valve body (1), water inlet pipe (2), spool (6), connecting rod (3), baffle plate (5) and ball float (4).The lower end of spool (6) is a plush copper (61), and the inboard of plush copper (61) is provided with rubber seal (62).Rubber seal (62) is set, can guarantees that plush copper (61) is pressed in inlet opening (51) good airproof performance when going up.In addition, also be provided with locating hole (7) in valve body (1), the internal diameter of locating hole (7) is a bit larger tham the external diameter of spool (6), and spool (6) passes this locating hole (7).Like this, can guarantee spool (6) position stability in up and down, prevent the drainage that takes place because of the skew of spool (6) position.
Claims (3)
1, a kind of tank intake valve of water, comprise spool (6) in the valve body (1), water inlet pipe (2), valve body (1), be hinged on connecting rod (3) and the terminal ball float (4) of connecting rod (3) on the valve body (1), it is characterized in that being provided with in the valve body (1) baffle plate (5), inlet opening (51) is arranged in the baffle plate (5), spool (6) passes inlet opening (51), the upper end of spool (6) is hinged in the middle of the connecting rod (3), and the lower end of spool (6) is a plush copper (61).
2, tank intake valve of water according to claim 1 is characterized in that described plush copper (61) inboard is provided with rubber seal (62).
3, tank intake valve of water according to claim 1 and 2 is characterized in that also being provided with in the valve body (1) locating hole (7), and the internal diameter of locating hole (7) is worked energetically the external diameter of spool (6) slightly, and order spool (6) passes this locating hole (7).
