SU101847A1 - Device for creating pulsations of water pressure - Google Patents

Description

The device can be used in multi-jet fountains. It serves to create a nulling of the water head, in order to make the jets character real.

Poor devices solve this problem with the help of complex mechanisms.

The feature of the device according to the invention consists in its constructive implementation, which provides the pulsation of water pressure using simpler technical means.

FIG. 1-5 show embodiments of the device according to the invention.

A centrifugal pump (1) feeds a vessel (2) with a siphon spillway through a supply line - pipeline (3). Below the vessel (2), the receiving tank (4) of the pressure line (5) of the fountain is placed. Water enters the pump through the pipeline (6). In order to provide constant water pressure, in order to create jets of some initial length in the fountain, the receiving tank (4) can be connected via a valve and pipe (7) to the supply pipe (3) (Fig. 2).

According to the invention, the device can be implemented with several vessels (2) (FIG. 3) equipped with a siphon spillway with an appropriate number of threading lines (3) and (8). Each node of the vessels (2) has a receiving tank (4). Such a device, in comparison with vigorous pigmentation, gives a smaller number of variations of the change in jet outflow pulses. This device can ensure the imposition (in time) of one pulse in the water supply to the other but with a separate pressure line m. For this, the pipelines (8) with intermediate tanks (9) (Fig. 3) of different tanks are connected to the supply pipe (3).

In order to ensure a predetermined pattern of change in the head of the fountain, zero-maximum-zero (Fig. 1) and minimum-maximum-minimum (Fig. 2), the amount of water entering the vessel (2) must be less than that consumed by the fountain jet. The operation of the device of FIG. 3 is similar to the operation of the device of FIG. 1 and also takes place according to the principle of operation of the device according to FIG. 2. For this, the receiving tank (4) is connected by a pipeline (10) to a supply pipeline (3).

In the device of FIG. (4) above the receiving tank (4) there are several vessels (2) with siphon spillways, the drain pipes (11) of which are directed B to the tank (4). This embodiment of the device aims to periodically change the amount of water entering the discharge line (5) of the fountain. The change in pressure occurs according to the zero-zero-zero scheme, and when the receiving tank (4) is connected by a pipeline (10) with a supply pipeline (3) -minimum-maximum-minimum.

In Ustguil but FIG. 5, the receiving tank (4) is made either with a section that varies in height or is made up of several tanks arranged vertically and interconnected. The tanks have different volumes, and the upper one performs (;. Open, and the rest are closed. In such a device, the change in water pressure can be abrupt or smooth. The latter is achieved if the upper capacity of the receiving tank is connected to the feed pipe (3) via a pipeline ( 10) with a tap.

The centrifugal pump (1) operates through the pipeline (6) and takes water from the fountain pool and pumps it to the pipeline (3) in the vessel (2) or simultaneously through the pipeline (7) (FPG. 2) NLP (10) (FNG). 5) to the receiving tank (4). On the pressure line (5), water is supplied directly to the fountain nozzles. A pulsation device is placed away from the fountain in a suitable height of adequate structure, which depends on the required head and the length of the water jets.
