Abstract
The utility model relates to a water inflow automatic control valve for an internal floatation water tank, which can make the water flow close reliably. A floating ball is arranged in a cylinder body of a valve, and a closed plug and a guide rod are arranged passing through the center of the floating ball. Under the action of buoyancy and water pressure, the closed plug is driven to control the valve to achieve the purpose of reliable closure. The utility model can be used for a toilet water tank and control systems arranged in other liquid tanks.
Description
The utility model relates to the valving that a kind of controlled water flow enters casing, especially can improve the float-ball type valve of its closed reliability.
Present known tank ball-float valve, its ball float links to each other with valve body by lever, controls water inlet and closed state by the height and the buoyancy function of liquid level.But when water pressure is much higher than the suffered buoyancy of ball float, the closed reliability of valve will reduce, even can not be closed.General float valve can not guarantee closed reliability.
The purpose of this utility model provides a kind of float valve can control water inlet and closed state, and has improved its closed reliability.
The purpose of this utility model is achieved in that the external ball float with traditional float valve changes and puts ball float in valve cylinders, under the acting in conjunction of ball float buoyancy and water pressure, and the water inlet of control valve and closed state; Make water pressure change closing force into, be able to reliable closed purpose by the anti-closing force of conventional valves.
Owing to adopt such scheme, can control water inlet preferably, and improve closed reliability, its simple structure, cost is low, long service life, the actual volume of raising water tank.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural section map; Fig. 2 is a water view into; Fig. 3 is the closed state schematic representation.
Among the figure 1, cylindrical shell; 2, spring; 3, guide rod; 4, ball float; 5, closure plug; 6, interlayer; 7, water intake; 8, intake pipe; 9, intake pipe; 10, cavity of resorption; 11, epicoele.
In the structural section map of Fig. 1, illustrate that this product is made up of cylindrical shell (1), spring (2), guide rod (3), ball float (4), closure plug (5), interlayer (6), ball float (4) places in the cylindrical shell (1), and cylindrical shell (1) is divided into cavity of resorption (10) and epicoele (11) by interlayer (6), can avoid current directly to impact ball float (4) like this; Current enter cavity of resorption (10) by water intake (7), enter water tank by intake pipe (8) again, when the water level in the water tank surpasses the height of interlayer (6), the part current enter epicoele (11) by intake pipe (9) by water tank, water level in the epicoele (11) raises with the water level in the water tank, ball float (4) is floated gradually, finally make valve closes.
Water inlet state when Fig. 2 represents that water level is low and the position of ball float (4).
When Fig. 3 represented that water level raises, under the acting in conjunction of water pressure and ball float (4) buoyancy, valve was reliably closed.
Implement this programme and should satisfy following formula requirement: closure plug (5) deadweight+spring (2) elastic force 〉=water pressure, otherwise can not intake; Ball float (4) buoyancy+water pressure＞closure plug (5) deadweight+spring (2) elastic force, otherwise can't be closed.Ball float (4) deadweight, friction etc. are ignored.
Claims (1)
- Internal floating type water tank water intake internally piloted valve, closure plug is installed in the valve cylinders, and ball float is installed on the valve by lever or guide rod, it is characterized in that ball float is placed in the valve cylinders, and closure plug and guide rod pass the circular hole at ball float center and install.
