Abstract
The utility model discloses a water inlet valve of a water tank for a flushing device in a closet, which comprises a valve casing, a valve lever, a closed rubber element, a switch lever and a floating ball, wherein the end head of the valve lever in the valve casing is provided with the rubber element, the fulcrum of the switch lever is hinged on the valve casing, one end is hinged with the extended end of the valve lever, and the other end is connected with the floating ball. The utility model is characterized in that a spring is arranged between the end head of the valve lever in the valve casing and the corresponding valve casing. Compared with the prior art, the utility model has the advantages that the water inlet can automatically close when the floating ball needs dismounting for maintenance or adjustment, the closed rubber part is comparatively durable, etc.
Description
The utility model belongs to the inlet valve of the parts of lavatory flushing device for toilet, particularly a kind of water tank.
The tank intake valve of water of the present lavatory flushing device for toilet that generally uses, structure comprises valve casing, valve lever, closed rubber parts, switch lever, ball float, wherein closed rubber parts is loaded on the valve lever lower end, valve casing and hinged with switch lever one end is stretched out in the valve lever upper end, and ball float is connected in the switch lever the other end.Closing of this inlet valve is buoyancy by ball float fully, and when maintenance or when adjusting inlet valve and need dismantle ball float, water intake then can't be closed, and this has caused inconvenience for maintenance and adjustment work.Another problem is that closed rubber parts is a rubber tissue, and because of thinner thickness is not durable, this has also increased the workload of changing.
The purpose of this utility model provides a kind of inlet valve of improved flushing device for toilet water tank, and water intake can be closed automatically when needs dismounting ball float.
The utility model is achieved in that a kind of inlet valve of flushing device for toilet water tank, comprise valve casing, valve lever, closed rubber parts, switch lever, ball float, wherein valve casing includes intake pipe, water intake, water outlet and lever support, valve lever is placed through on the valve casing, closed rubber parts is being adorned in its termination that is positioned at valve casing, the fulcrum of switch lever is hinged on the lever support of valve casing, one end of lever is hinged with the valve lever overhanging end, the other end is connected with ball float, it is characterized in that between the termination of valve lever in valve casing and the corresponding valve casing part spring being housed.
Such scheme can be oppressed closed rubber parts and make it close water intake owing between the termination of valve lever in valve casing and the corresponding valve casing part spring is housed when the dismounting ball float, water tank is no longer intake, so that keep in repair or the carrying out of adjustment work.In normal operation, because the gravity of ball float is enough to overcome spring force, so the existence of spring does not influence the normal water inlet of water tank.If more closed rubber parts is made solid hemispherical structure in addition, not only there are good closed performance but also rubber body thicker bigger, thus more durable, can reduce and repair the number of times of changing.
Below in conjunction with accompanying drawing the utility model is done further to describe.
Fig. 1 is the vertical profile schematic representation of a kind of scheme of the utility model.
Fig. 2 is the plan view of Fig. 1.
With reference to Fig. 1～Fig. 2, this inlet valve, comprise the valve casing 1 that connects and composes by multi-section part, valve lever 2, closed rubber parts 3, switch lever 4, ball float 5, wherein valve casing 1 comprises intake pipe 6, water intake 7, water outlet 8, lever support 9, valve lever 2 is placed through on the valve casing 1, closed rubber parts 3 is being adorned in its termination 10 that is positioned at valve casing 1, the fulcrum of switch lever 4 is hinged on the lever support 9 of valve casing 1, one end and valve lever 2 external parts of lever 4 are hinged, the other end is connected with ball float 5 by ball lever 11, feature be the termination 10 of valve lever 2 in valve casing 1 with corresponding valve casing 1 part between a spring 12 is housed.Closed rubber parts 3 is solid hemispherical structure.In addition, there is a step 13 intake pipe 6 bottoms and is lined with a rubber ring 14, the irrigating gate of the water tank that is used to be tightly connected.
During use when cistern water level descends, ball float 5 descends, the spring that the gravity of ball float 5 overcomes spring 12 rises valve lever 2, water intake 7 is opened, tap water enters valve casing 1 inner chamber through intake pipe 6, water intake 7, enters water tank from water outlet 8, when cistern water level rises, ball float 5 rises, and valve lever 2 moves down closes water intake 7.When the dismounting ball float, spring 12 roof pressures closed rubber parts 3, so water intake 7 still is in closed condition.
Claims (2)
1, a kind of inlet valve of flushing device for toilet water tank, comprise valve casing, valve lever, closed rubber parts, switch lever, ball float, wherein valve casing includes intake pipe, water intake, water outlet and lever support, valve lever is placed through on the valve casing, closed rubber parts is equipped with in its termination that is positioned at valve casing, the fulcrum of switch lever is hinged on the valve casing lever support, one end of lever is hinged with the valve lever overhanging end, the other end is connected with ball float, it is characterized in that between the termination of valve lever in valve casing and the corresponding valve casing part spring being housed.
2, by the described inlet valve of claim 1, it is characterized in that described closed rubber parts is solid hemispherical structure.
