Float chamber with lower needle closure

The float chamber according to the invention is a special type of float valve.

It was designed to produce a small gravity dispenser of liquid chemicals used in the treatment of drinking water, which serves to create a constant level above the regulator.

The essence of the invention is apparent from the drawing:

The float chamber (9) according to the invention comprises a body (3), a bottom (7) and a lid (2). A float (4) is provided inside the chamber with a bottom (5). In the center of the float (4) is formed a channel (8) through which the feed tube (1) passes, provided at its lower end with a seat (10).

On the bottom (5) of the float (4) there is a closure needle (6) which fits into the seat (10) of the supply tube (1). Apertures (11) are provided around the cap needle (6) for free liquid flow when the cap is opened. The opening (12) serves for venting the chamber (9) ·

The liquid flows through the lance (1) through the openings (11) into the float chamber (9). The inflowing liquid fills the chamber (9) and causes the float to lift and thereby gradually close the closure.

The invention can be used as a small simple and reliable float closure for small prints.

The invention relates to a float chamber with a lower needle closure for maintaining the level at the same level.

Bacteriological safety of drinking water from small sources is ensured by dosing of sodium hypochlorite solution using various gravity dispensers. Dosing with electrically powered devices is generally not possible, as the vast majority of these sources do not have a power connection. Therefore, the only commonly used device is a drip bottle. This bottle has two necks - one filling at the top of the bottle and the other one at the bottom. A drain hose with an inside diameter of about 3 mm is connected to the lower neck; A stopper is fitted in the upper throat through which the air inlet pipe extends to the bottom of the bottle. A capillary limiting the amount of air passing through it and a drying silica gel filter are mounted on the outside of the tube.

After the bottle has been filled with the solution and the bottle is capped, the solution starts to drain through the drainage tube. However, since only a limited amount of air is allowed to pass through the capillary, vacuum will begin to form in the bottle. The value of the generated vacuum depends on the height of the liquid column inside the bottle, the size of the capillary tube and the vertical height.

the distance from the bottom of the bottle to the bottom of the bottle. The vacuum generated causes the bottle to behave as if it were only filled up to the inner end of the air supply tube, and this is not dependent on the filling value of the bottle with the solution. Depending on the capillary size, the actual dose of the solution depends only on the vertical distance of the tube mouth from the bottom of the bottle. Clogging of the capillary with atmospheric moisture should prevent the desiccant silica gel filter.

A dispenser of this type has a number of disadvantages:

The bottles are difficult to handle, the silica gel cartridge needs to be changed frequently, after uncorking, the solution drains freely due to the removal of the vacuum, and the same happens when the dispenser is put into operation, except for special glass bottles. A frequent source of defects is capillary clogging.

The dispenser does not have the above-mentioned dispensers using a float chamber with a lower needle closure provided with a float according to the invention, characterized in that a longitudinal axis of the float is provided with a channel in which a feed tube is provided. a cap located at the bottom of the float, with holes formed around the cap needle.

In the float chamber according to the invention the level is kept constant by the float lock. The shape of the float and the lower needle closure allow a perfect use of the interior space of the chamber and thus its small constructional dimensions while maintaining simplicity and reliable closing.

An exemplary embodiment of a float chamber according to the invention is shown in the attached drawing.

The float chamber according to the invention is formed by a body 2, a bottom 2 ^{and a} cover 2. Inside the chamber there is a float 6 provided with a bottom part 2 · 4 θ of the center of the float 4 a channel 8 is formed.

-4239 103 through which the feed tube 2 provided with a seat 10 at its lower end. On the bottom 2 of the float 4 is located a closure needle 6 which fits into the seat 10 of the supply tube 2.

Apertures 11 are formed around the closure needle 6 of the closure to freely drain the liquid when the closure is opened. The opening 12 serves to vent the float chamber 2.

The liquid flows through the inlet tube 2 through the openings 11 into the float chamber. The flowing liquid fills the chamber 9 and causes the float 4 to lift and thereby gradually close the closure.

When the closure needle 6 engages the seat 10, the closure is in the closed position.

In practice, the bottom needle lock float chamber of the present invention has been used in the construction of a small gravity liquid chemical dispenser. This dispenser consists of a float chamber according to the invention which has an adjustable closure on the drain hose about 120 mm below the level. Since a constant column of the dosing solution is guaranteed over the seal by the float chamber, the flow rate depends only on the setting value of the adjustable seal.

The dispenser has been successfully tested and has a number of advantages over other types of gravity dispensers, especially in higher reliability and easier operation.
