Abstract

The utility model discloses an automatic inlet valve with a floating ball lifting or falling vertically to centre. The floating ball is vertically connected with a small draw rod by a connecting rod, the small draw rod passes through the center of a valve flap and goes into a water cavity body, and the end of the small draw rod is in shape of a small ball; a pore is arranged between the small draw rod and the valve flap and between the small draw rod and an inner sleeve thereof, another water cavity body is arranged between two inner shells, and five water through holes are arranged between the two inner shells and the valve body. The utility model has the advantages of reasonable structure, small quantity of wearing parts, agile on-off action, easy use and long service life.

Description

The automatic water inlet valve of ball float vertical centre lifting

The utility model relates to a kind of improvement of water intaking valve, and this water intaking valve is applicable to that water receiver or water tank are as a kind of water closing device.

World today's water shortage problem is more and more outstanding, drainage has become a difficult problem that presses for solution, there are many technical schemes to propose the way that solves for this reason, for example No. 94245936.9, Chinese patent is about proposing a kind of water intaking valve structure in " a kind of automatic water inlet valve of water tank ", the rubber seal and the movable valve block that are positioned at water inlet pipe mouth join, valve block is conical, wherein part is hollow, there is an active pin shaft to put inside, bearing pin length is more longer slightly than valve block width, the upper end of valve block is tangled it by a bearing pin, spool is spherical in shape or conical, and the automatic water inlet valve sealing of this water tank adopts secondary action to finish its structure more complicated, the manufacturing cost height, assembly difficulty is big.

Task of the present utility model provides a kind of novel automatic water inlet valve, this water intaking valve rational in infrastructure, and few easy workout part, flexible movements, easy to use, the life-span is long.

Task of the present utility model is to finish in such a way, this automatic water inlet valve adopts the mode of ball float vertical centre lifting to work, and change the pressure differential of cavity before and after the valve as power, thereby reach the on-off action of water intaking valve, because the buoyancy of ball float is not directly to be used for the switch motion of by-pass valve control, thus the requirement of buoyancy is reduced relatively, and the fulcrum of power transmission is less, the loss that friction causes is little, thus the quality and the application life of having improved automatic water inlet valve effectively.

Below in conjunction with accompanying drawing the utility model is further elaborated.

Fig. 1 is an automatic water inlet valve sectional view of the present utility model.

As can be seen from Figure, the ball float of this automatic water inlet valve (1) is the vertical centre lifting, and ball float (1) is vertically connected on lower link bar (3) by connecting rod (2), and lower link bar (3) passes from the center of valve sheet (4), and it is indoor to enter water chamber " A ".And can contact with valve inner support (5), the end of lower link bar (3) is coccoid, between the interior cover (6) of lower link bar (3) and valve sheet (4) and bottom thereof a hole (7) is arranged, one water chamber " B " chamber is arranged between inner casing (8) and (9) in addition, inner casing (8), (9) and be provided with limbers (a) between the valve body (10), (b), (c), (d) and (e), at valve gap (11) and connecting rod (2) joining place a cellucotton leak-proof gasket (12) is arranged, valve gap (11) is to be connected with sealing ring (13) with valve body (10), also fill up a sealing ring (14) between inner casing (8) and (9), at bottom inner casing (8) and valve inner support (5), then use water proof ring (15) between inner casing (9) and the valve body (10), (16) separated.

When the drawdown in the water receiver behind certain position, ball float (1), connecting rod (2) and lower link bar (3) are subjected to action of gravity, break through hydraulic action on hole (7) pressure and begin to descend, the pressure of water chamber " A " is reduced, make the pressure in the water chamber " B " reach relative maximum, " c " flows into water from the limbers, and through in the inflow water collector of limbers " d " " e ".

When water enter reach some in the water receiver after, ball float (1) rises, drivening rod (2) and lower link bar (3) are up carried together, the coccoid end of lower link bar (3) clogs the hole (7) at valve sheet (4) center, also affect simultaneously valve sheet (4) to rise, up to pushing down limbers " c ", at this moment pressure ratio water chamber " B " pressure of water chamber " A " is big, so valve sheet (4) can be pushed down limbers " c ", the water of water chamber " A " also just stops to flow like this, reaches the purpose of Guan Shui.

Claims

1. a ball float (1), connecting rod (2), valve body (10), the ball float vertical centre lifting automatic water inlet valve that valve gap (11) is formed, it is characterized in that: ball float (1) is vertically connected on lower link bar (3) by connecting rod (2), lower link bar (3) passes from the center of valve sheet (4), it is indoor to enter water chamber " A ", and can touch mutually with valve inner support (5), the end of lower link bar (3) is coccoid, between the interior cover (6) of lower link bar (3) and valve sheet (4) and bottom thereof a hole (7) is arranged, one water chamber " B " chamber is arranged in addition, inner casing (8) between inner casing (8) and (9), (9) and be provided with limbers " a " between the valve body (10), " b ", " c ", " d ", " e ".

2. press the ball float vertical centre lifting automatic water inlet valve of claim 1 defined, it is characterized in that: a cellucotton leak-proof gasket (12) is arranged at valve gap (11) and connecting rod (2) joining place, valve gap (11) is to be connected with sealing ring (13) with valve gap (10), also fill up a sealing ring (14) between inner casing (8) and (9), inner casing (8) and valve inner support (5) in the water intaking valve bottom, and then separated by water proof ring (15), (16) between inner casing (9) and the valve body (10).
