Description

Изобретение относится к области водоснабжения, а именно к водонапорным башням и может быть использовано в системах водоснабжения веселенных пунктов и промышленных предприятий. ,The invention relates to the field of water supply, namely to water towers and can be used in water supply systems of populated areas and industrial enterprises. ,

Известны водонапорные башни, содержащие ⁵три бака, расположенные по высоте один над другим. В среднем баке расположен поплавок для поддержания заданного уровня, а нижний и верхний баки соединены посредством труб через насосную установку [1].Known water towers containing ⁵ three tanks located in height one above the other. A float is located in the middle tank to maintain a given level, and the lower and upper tanks are connected via pipes through the pumping unit [1].

Недостатком башни является сложность ее устройства и эксплуатации и пониженная надежность, обуславливаемые наличием трех баков, поплавкового регулятора уровня и насосной установки.The disadvantage of the tower is the complexity of its construction and operation and reduced reliability, due to the presence of three tanks, a float level controller and a pumping unit.

Известны также водонапорные башни, содержащие напорно-регулирующий бак, установленный на опорах, подающе-отводящий трубопровод^ в которых отметка низа бака принимается из условия создания максимального расчетного напора при минимальном уровне воды в |баке [2].Water towers are also known, containing a pressure-regulating tank mounted on supports, a supply-discharge pipe ^ in which the mark of the bottom of the tank is taken from the condition of creating the maximum design head with a minimum water level in the | tank [2].

Так как при снижении водопотребления требуемый напор также снижается, а уровень воды в баке колеблется между минимальным и максимальным значениями, то, очевидно, такие башни большую часть времени создают напор, значительно превышающий требуемый. Это приводит к перерасходу электроэнергии, затрачиваемой на подачу воды и к снижению расхода насосов, что в свою очередь требует увеличения объема запасно-регулирующего бака.Since with a decrease in water consumption, the required pressure also decreases, and the water level in the tank fluctuates between the minimum and maximum values, it is obvious that such towers most of the time create a pressure that significantly exceeds the required. This leads to an excessive consumption of electricity spent on the water supply and to a decrease in the pump flow rate, which in turn requires an increase in the volume of the reserve-control tank.

Цель изобретения — устранение указанных недостатков.The purpose of the invention is the elimination of these disadvantages.

Для этого подающе-отводящий трубопровод снабжен обратным клапаном и регулятором давления, установленными параллельно.For this, the supply and outlet pipe is equipped with a check valve and a pressure regulator installed in parallel.

Бак устанавливается на такой высоте, чтобы при минимальном уровне воды в баке и открытом регуляторе давления башней создавался максимальный расчетный напор. Обратный клапан и регулятор давления применены с целью гашения излишнего напора в период сработки воды из бака, что приводит к увеличе3 нию расхода насосов и, следовательно, к уменьшению расхода воды из бака.The tank is installed at such a height that with a minimum water level in the tank and an open pressure regulator the tower creates the maximum design head. The non-return valve and pressure regulator are used to suppress excessive pressure during the period of water depletion from the tank, which leads to an increase in the flow rate of the pumps and, consequently, to a decrease in the flow rate of water from the tank.

На чертеже дана водонапорная башня.The drawing shows a water tower.

Башня имеет запасно-регулирующий бак 1, подающе-отводящий трубопровод 2, оборудованный параллельно установленными обратным клапаном 3 и регулятором 4 давления. Башня соединена с наружной разводящей сетью-трубопроводом 5.The tower has a reserve-regulating tank 1, a supply-outlet pipe 2, equipped in parallel with a non-return valve 3 and a pressure regulator 4. The tower is connected to the external distribution network-pipeline 5.

II

Водонапорная башня работает в двух режимах.The water tower operates in two modes.

Первый режим, при котором насосной. станцией подается больше воды, чем, отбирается из разводящей сети. В этом случае в связи с повышением давления, регулятор закрывается, 15 и избыток воды поступает в запасно-регулирующий бак Г через обратный клапан 3.The first mode in which the pumping. the station supplies more water than is taken from the distribution network. In this case, due to the increase in pressure, the regulator closes, 15 and the excess water enters the emergency control tank G through the check valve 3.

Второй режим, при котором насосной станцией подается меньше воды, чем отбирается из разводящей сети. В этом случае недостающий 20 расход поступает из запасно-регулирующего бака 1 через регулятор 4 давления, который будет поддерживать требуемый для потребителя напор. В связи с тем, что часть напора гасится регулятором давления, свободный напор в месте расположения башни снижается, это приводит к увеличению расхода насосной станции, а, следовательно, к менее интенсивной $ сработке запасно-регулирующего бака, что позволяет уменьшить его объем.The second mode, in which the pumping station delivers less water than is taken from the distribution network. In this case, the missing flow rate 20 comes from the reserve control tank 1 through the pressure regulator 4, which will maintain the pressure required for the consumer. Due to the fact that part of the pressure is quenched by the pressure regulator, the free pressure at the location of the tower is reduced, this leads to an increase in the flow rate of the pumping station, and, consequently, to a less intensive operation of the reserve-regulating tank, which reduces its volume.

Claims

The invention relates to the field of water supply, in particular to water towers and can be used in water supply systems of settlements and industrial enterprises. Known water towers, containing three tanks, located one above the other in height. In the middle tank, there is a float to maintain a predetermined level, and the lower and upper tanks are connected via pipes through a pump installation 1. The tower’s drawback is the complexity of its design and operation and reduced reliability due to the presence of three tanks, a float level controller and a pump installation. Also known are water towers containing a pressure-regulating tank, installed on supports, giving a discharge in which the mark of the bottom of the tank is taken from the condition of creating a maximum pressure head with the minimum water level in the tank 2. Since the water consumption required is reduced Since the pressure also decreases, and the water level in the tank fluctuates between the minimum and maximum values, it is obvious that such towers create a pressure much longer than the required time for most of the towers. This leads to waste of the energy consumed for the supply of water and to a decrease in the consumption of pumps, which, in turn, requires an increase in the volume of the reserve-regulating tank. The purpose of the invention is to eliminate these disadvantages. For this, the supply and discharge pipe is provided with a check valve and a pressure regulator installed in parallel. The tank is installed at such a height that with a minimum water level in the tank and an open pressure retreat tower the maximum design head is created. A check valve and a pressure regulator are used to quench the pressure head during the period when the water is drained from the tank, which leads to an increase in the flow rate of the pumps and, consequently, to a decrease in the water flow from the tank. In the drawing given water towers. The tower has a reserve control tank 1, supply and drainage pipe 2, equipped with a parallel installed check valve 3 and pressure regulator 4. The tower is connected to the external distributing network-pipeline 5, the water tower works in douh mode. The first version, prn which pumping. the station is supplied with more water than it is taken away from the nets of the nets. In this case, due to increased pressure, the regulator closes and excess water enters the reserve-regulating tank 1 through the check valve 3. The second mode, in which less water is pumped by the pumping station than it is taken from the network. In this case, the missing flow comes from the spare-regulating tank 1 through the pressure regulator 4, which will maintain the head required for the consumer. Due to the fact that part of the pressure is extinguished by regulating the pressure, the free pressure at the location of the tower decreases, this leads to an increase in the pumping pump consumption and, consequently, to a less intensive drawdown of the reserve-regulating tank, which reduces its volume. Claims. A water tower containing a reserve control tank mounted on supports, a feed-discharge pipeline, characterized in that, in order to simplify the design and increase the reliability of the tower, the feed-discharge pipeline is equipped with a check valve and a pressure regulator installed in parallel.
