Abstract

The utility model relates to a vertical brake type float automatic valve, which is used for tanks in buildings, comprising a valve body, pistons, push rods and a floating ball. The utility model is characterized in that the upper end of the push rods is connected with the pistons, and the lower end is connected with the floating balls. The push rods are penetrated through the locator slides of the lower part of the valve body to make the push rods move vertically in the locator slides. When the water level of the tank rises to the horizontal position that the floating balls is in, the push rods are impelled by the buoyancy of the floating ball, the pistons are propelled into the piston bushes to clog a water inlet, and the watertight purpose is finally achieved. When the tank water level drops to below the horizontal position of the floating ball is in, the floating balls and the push rods together with the pistons drop automatically, the pistons leave the piston bushes, the water goes from the water inlet into the tank through a water outlet, the floating ball is raised up again until the water level rises to the upper limit line, and the watertight purpose is realized. The utility model has the advantages that the push rods move vertically, the moving distance is short, the parts are uneasy to damage, the structure is simple, and the cost is low.

Description

Vertical brake type float automatic valve

The utility model relates to the autocontrol valve that uses in the water reservoir in a kind of building.

Existing water reservoir adopts Lever type ball float self-acting valve mostly, this self-acting valve is by valve body, piston, the lever of a ball float and a band right angle type push rod is formed, lever is horizontal, one termination ball float, the lower end of another termination right angle type push rod, the right angle type push rod is positioned on the bearing of valve body lower portion by axle, and the other end of right angle type push rod penetrates in the piston, be in limited time high at the water reservoir water line, withstand piston, allow it block water intake, to stop to continue water supply, along with the water level in the water reservoir descends gradually, the horizontal position of ball float also progressively descends immediately, and under the drive of lever, the right angle type push rod reduces gradually until the pressure of removing fully piston, at this moment, because the pressure of current can be pushed piston automatically open in the intake pipe, water just enters water reservoir through water outlet.But this Lever type ball float self-acting valve, because lever is horizontal, in the corner of right angle type push rod, an axis hole is arranged, when the pond middle water level goes up by paramount restrict water supply, the buoyancy of ball float makes horizontal lever obtain a great moment, often, often in the joint of ball float and lever, and the axis hole of right angle type push rod, very easily because of stressed excessive dialysis, make water reservoir water inlet out of control and cause the wasting phenomena of spilling water.

The purpose of this utility model is to provide a kind of novel self-acting valve, and this self-acting valve can significantly reduce the phenomenon that causes water level spilling water waste out of control because of the damage of parts.

The technical solution of the utility model (containing embodiment) is as follows: a kind of vertical lock standard ball float self-acting valve, form by valve body (1), piston (2), push rod (3), ball float (4).Water intake (5) and water outlet (6) are arranged at valve body (1) top, between water intake (5) and water outlet (6), piston sleeve (7) is arranged, piston sleeve (7) becomes movingly with the size of piston (2), one cavity (8) is arranged at valve body (1) bottom, a push rod locator slide (9) is arranged under the cavity (8), push rod (3) passes wherein, and can move up and down freely, push rod (3) upper end utilizes screw thread to be connected with the lower end of piston (2), push rod (3) lower end also is to utilize screw thread to be connected with the upper end of ball float (4).

Working principle of the present utility model is as follows: after the water level in the water reservoir is lower than the horizontal position of ball float (4), ball float (4) is together with push rod (3) and piston (2), because the effect of power, will be automatically slide along the direction of the locator slide (9) of valve body (1) bottom, at this moment, piston (2) leaves piston sleeve (7), and water intake (5) and water outlet (6) in the valve body (1) communicate.The water of intake pipe, to enter in the water reservoir through water intake (5), piston sleeve (7) and the water outlet (6) of valve body (1), water level in water reservoir raises gradually, when arriving the horizontal position of ball float (4), because buoyancy function, ball float (4) will raise along with the progressively rising of pool inner water position, promote push rod (3) simultaneously, promote piston (2) by push rod (3) again, enter piston sleeve (7) fully until piston (2), water intake (5) is blocked, and intake pipe just stops to supply water to water reservoir, and the water level in the pond stops to rise at once.

Advantage of the present utility model is: because the buoyancy of ball float vertically acts on piston by push rod, its move distance is short, and various component are not fragile, and simple in structure, and cost is lower than traditional Lever type ball float self-acting valve.
