Description

This utility model relates to devices designed for repeated measurement and delivery of predetermined volumes of liquid and is intended for use in a standpipe to prevent uncontrolled release of water when the column lever is pressed.

Serial water columns have a drawback that makes it possible to spend water uncontrollably - when the column lever is jammed, the valve remains in the open position and water can be discharged for an unlimited time until the lever is released from jamming.

A metering device is known - flush valves, in which a shut-off element, for example, in the form of a plug in the form of a body of revolution with an opening for passing a stream of water, when shut off, rotates around its axis [1], which are capable of releasing a metered amount of water per working cycle. [2]. A disadvantage of the devices is the impossibility of dispensed dispensing of different volumes, since the mismatch of the volume of a large capacity with the multiplicity of the dispensed amount of dispensed water column will also lead to unnecessary water losses, and jamming of the lever or button on these structures leads to the possibility of unlimited water analysis.

A dispenser is also known, comprising a housing with a spout and a dispensing tap, the latter comprising a housing with a shut-off valve and a start button [3].

However, this device does not contain a pre-configured regulator of water flow, which leads to an unjustified increase in its flow.

A known utility model [4] for dispensing a water-folding column (taken as a prototype) consisting of a closed casing made in the form of a hydraulic cylinder, in which a rod is located, passing through the upper support serving for it, at the inner end of which a piston with two holes is fixed , which serve for the passage of fluid from the upper cavity of the cylinder to the lower, and on its lower side there is a flap valve, the device includes threads applied to the central hole of the rod, into which on the side there is a screw that fixes the piston on the rod, and on the other hand, an adjustment screw is included in the central hole of the rod, having a narrowing at the lower end in the form of a needle blocking the hole in the screw, and in the rod, in its over-piston part, there are two thin axes perpendicular to its axis holes.

The disadvantage of the prototype is the dosed tempering of the same volume, which leads to unnecessary water loss if the tank has a small volume or if you want to repeat the work cycle if the tank has a large volume. And the discrepancy between the volume of a large capacity and the multiplicity of the dosed quantity of water released by the column will also lead to unnecessary water losses. In addition, jamming of the lever or button on such structures again leads to the possibility of unlimited analysis of water.

The purpose of creating a utility model is to exclude uncontrolled and unlimited drawdown.

The technical result of this utility model is to achieve the dispensing of water tempering and is achieved by incorporating a one-way hydraulic damper installed inside the valve spring.

The composition of the device is shown in figures 1 and 2, which depicts a column collapsible metered tempering of water with an open and closed valve, respectively, where: 1 - valve body, 2 - casing, 3 - collapsible pipe, 4 - lever with drawstring, 5 - casing cover, 6 - ejector, 7 - sealing sleeve, 8 - damper spring, 9 - valve, 10 - valve plate, 11 - valve seat, 12 - damper stem, 13 - valve spring, 14 - single-acting damper, 15 - connecting branch pipe.

The column folding dosed vacation works as follows.

To analyze the water, press the lever (4), which, through the wings, informs the forward movement of the water pipe connected rigidly through the ejector (6) to the valve (9), lowering them down and compressing the valve spring (13). Sinking down, the valve (9) and its seat depart from the valve disc (10) attached to the damper rod (12). The damper spring (8) presses on the valve disc (10), pushing it toward the valve seat (11), however, the damper (14) does not allow the valve disc to approach the valve seat quickly.

While the valve disc (10) approaches the valve seat (11), a metered release of water occurs, and the dosing volume depends on how far the lever of the water column (4) is lowered down and, accordingly, how far the valve seat (11) is moved away from the plate (10). The lower the lever is lowered, the greater the dosed volume of released water.

Jamming of the lever in any position will not allow unlimited uncontrolled water analysis, since the valve disc (10), under the influence of the damper spring (8), will nevertheless gradually approach the valve seat (11) and block the flow of water from the network.

With the valve closed (Fig. 1), the water remaining in the water pipe through the openings in the ejector will merge into the internal cavity of the column casing.

When the valve is opened for the next water intake, the water that has merged into the internal cavity of the casing will be sucked out by the ejector and fed into the water pipe.

The design of a one-way damper is shown in Fig. 3 (a - when the rod moves up; b - when the rod moves down), where it is indicated: 9 - valve, 10 - valve plate, 11 - valve seat, 12 - damper rod, 13 - valve spring , 16 - cylinder, 17 - piston, 18 - bypass holes, 19 - diaphragm, 20 - adjusting nut, 21 - spring, 22 - calibrated hole, 23 - lip seal.

The proposed column uses a one-way hydraulic damper as a valve closing retarder. As a moderator, the damper used in the proposed column as a damper works only in one direction, when its rod (12) moves downward under the influence of the force applied to it.

The hydraulic one-way damper works as follows:

When the rod moves up, the working fluid located in the upper cavity of the cylinder (16) above the piston (17) through the bypass holes (18) flows freely into the lower cavity, squeezing the diaphragm (19).

When the rod moves downward from the applied longitudinal force, the spring (21) presses the diaphragm (19) against the lower surface of the piston (17), blocking the bypass holes (18). The transfer of the working fluid from the lower cylinder cavity under the piston to the upper cylinder cavity above the piston becomes possible only through a calibrated orifice plate (22). The selected kinematic viscosity of the working fluid does not allow it to flow through the calibrated aperture of the diaphragm instantly, thereby slowing the stroke of the rod (12) to the desired speed.
