A water supply system consists of a water intake line connected to at least two sources of water in the form, respectively, of an external water main and an alternative source comprising a storage tank and a water supply line, the system being capable of predominantly supplying water from the alternative source as a result of the presence of a vessel on the water supply line of the alternative source, which provides for a pressure greater than the pressure of the external water main.

Description

Система водоснабжения. Water supply system.
Изобретение относится к системам водоснабжения зданий и сооружений.The invention relates to water supply systems for buildings and structures.
Известны системы водоснабжения, где линия забора воды подключена к внешнему водопроводу муниципальному, городскому, локальному и т.д. Также из уровня техники известны системы водоснабжения с двумя источниками, где линия забора воды подключена к внешнему водопроводу и одновременно к альтернативному источнику воды, например, емкости с накопленной дождевой водой. Такие систему водоснабжения могут применяться как для холодной, так и для горечей воды. Water supply systems are known, where the water intake line is connected to an external municipal, city, local, etc. water supply system. Also known from the prior art are water supply systems with two sources, where the water intake line is connected to an external water supply and at the same time to an alternative source of water, for example, tanks with accumulated rainwater. Such a water supply system can be used for both cold and bitter water.
Из уровня техники известна система горячего водоснабжения по патенту JP6036016B2 (приоритет 30.08.2012), выбранная заявителем в качестве наиболее близкого аналога. Система состоит из линии забора воды на потребление, которая через управляющий клапан, подключена к внешнему водопроводу и к альтернативному источнику, выполненному в виде накопительной емкости, снабженной нагревателем, работающим от солнечной энергии, и датчиком температуры, функционально связанным с управляющим клапаном. Отбор воды на линию забора воды в единичный момент времени происходит только от одного источника - от водопровода или из емкости. Управляющий клапан имеет две рабочих положения: первое - забор воды от водопровода, при этом отбор воды из емкости перекрыт; второе - отбор воды осуществляется из емкости, отбор воды из водопровода перекрыт. В рамках отличительных признаков система работает следующим образом. Емкость заполняется холодной водой, после чего под воздействием солнечной энергии происходит постепенный нагрев воды с контролем температуры при помощи датчика. Если фиксируемая датчиком температура воды в емкости выше заданного уровня, то управляющий клапан переводится во второе положение и на линию забора воды поступает вода из емкости. Если фиксируемая датчиком температура воды в емкости ниже заданного уровня, то управляющий клапан переводится в первое положение, и вода на линию забора воды поступает из водопровода. Основным недостатком наиболее близкого аналога является сложность конструкции управляющего клапана, что снижает точность работы системы, так как клапан ждет сигнал датчика на срабатывание, то есть всегда есть время отклика при смене источника. Кроме того, сложная конструкция клапана снижает надежность и срок службы системы. Задачей изобретения и достигаемым за счет него техническим результатом является разработка новой системы водоснабжения с несколькими источниками, с увеличением эффективности использования альтернативного источника, при одновременно повышении надежности переключения между источниками. The prior art hot water system according to patent JP6036016B2 (priority 30.08.2012), selected by the applicant as the closest analogue. The system consists of a water intake line for consumption, which, through a control valve, is connected to an external water supply and to an alternative source, made in the form of a storage tank, equipped with a solar-powered heater and a temperature sensor functionally connected to the control valve. Water is withdrawn to the water intake line at a single point in time from only one source - from a water supply system or from a container. The control valve has two operating positions: the first - water intake from the water supply, while the water intake from the tank is blocked; the second - water is taken from the tank, water is taken from the water supply system is blocked. As part of the distinguishing features, the system works as follows. The container is filled with cold water, after which, under the influence of solar energy, the water is gradually heated with temperature control using a sensor. If the water temperature in the tank detected by the sensor is higher than the specified level, then the control valve is moved to the second position and water from the tank flows to the water intake line. If the temperature of the water in the tank detected by the sensor is below the specified level, then the control valve is moved to the first position, and water is supplied to the water intake line from the water supply. The main disadvantage of the closest analogue is the complexity of the design of the control valve, which reduces the accuracy of the system, since the valve waits for the sensor signal to operate, that is, there is always a response time when changing the source. In addition, the complex design of the valve reduces the reliability and service life of the system. The objective of the invention and the technical result achieved through it is the development of a new water supply system with multiple sources, with an increase in the efficiency of using an alternative source, while increasing the reliability of switching between sources.
Поставленная задача и заявляемый технический результат достигаются тем, что система водоснабжения состоит из линии забора воды, соединенной по меньшей мере с двумя источниками воды - внешним водопроводом и альтернативным источником, выполненном в виде накопительной емкости и линии подачи воды, выполнена с возможностью преимущественной подачи воды из альтернативного источника, за счет наличия на линии подачи воды из альтернативного источника бака, обеспечивающего давление выше давления водопровода, при этом система может дополнительно содержать редуктор, установленный в месте подключения внешнего водопровода к линии забора воды, блок очистки воды или линию промывки альтернативного источника водой внешнего водопровода. The set task and the claimed technical result are achieved by the fact that the water supply system consists of a water intake line connected to at least two water sources - an external water supply and an alternative source made in the form of a storage tank and a water supply line, made with the possibility of predominantly supplying water from alternative source, due to the presence of a tank on the water supply line from an alternative source that provides a pressure higher than the pressure of the water supply system, while the system may additionally contain a reducer installed at the point of connection of the external water supply to the water intake line, a water purification unit or a line for washing the alternative source with external water plumbing.
На фигуре 1 представлен пример простейшей схемы системы водоснабжения с двумя источниками. The figure 1 shows an example of the simplest scheme of a water supply system with two sources.
Система водоснабжения включает линию 4 забора воды, которая подключена, по меньшей мере, к двум источникам воды: внешнему водопроводу 1 и альтернативным источником 3. Альтернативный источник 3 включает емкость 5, линию подачи 2 с установленными на ней насосом 6 и баком 7. Бак 7 выполнен в виде, например, но не ограничиваясь только перечисленными вариантами водовоздушного бака, напорной емкости или бака с устройством нагнетания давления. The water supply system includes a water intake line 4, which is connected to at least two water sources: an external water supply 1 and an alternative source 3. An alternative source 3 includes a container 5, a supply line 2 with a pump 6 and a tank 7 installed on it. Tank 7 is made in the form, for example, but not limited to the listed options of a water-air tank, a pressure tank or a tank with a pressure injection device.
В рамках отличительных признаков система водоснабжения работает следующим образом. Водоснабжение здания или сооружения и подвод воды на потребление осуществляется по линии 4 забора воды, которая подключена, по меньшей мере, двум источникам воды. При этом внешний водопровод 1 является постоянным источником воды, а альтернативный источник 3 может быть заполнен водой, а может быть пустым. Эффективное использование альтернативного источника 3 подразумевает, что в случае, когда в альтернативном источнике 3 есть вода, поступление воды на линию 4 забора воды идет из альтернативного источника 3. Наличие воды в альтернативном источнике 3 означает, что емкость 5 заполнена водой, например, накопленной дождевой или талой снежной водой, или любой другой водой. Из емкости 5 вода с помощью насоса 6 вода поступает в бак 7. Если уровень воды в баке 7 выше минимального, то вода находится под давлением выше, чем давление внешнего водопровода 1. Таким образом, вода на линию 4 забора воды на потребление приоритетно поступает из альтернативного источника воды 3. Если уровень воды в баке 7 ниже минимального, то отбор воды на линию 4 забора воды на потребление идет от внешнего водопровода 1. При этом система водоснабжения функционирует управляющего клапана переключения потока. Отсутствие сложной системы переключения потоков обеспечивает повышенную надежность системы, таким образом, решается поставленная задача и достигается технический результат. As part of the distinguishing features, the water supply system works as follows. The water supply of a building or structure and the supply of water for consumption is carried out through the water intake line 4, which is connected to at least two water sources. In this case, the external water supply 1 is a constant source of water, and the alternative source 3 can be filled with water, or it can be empty. Efficient use of alternative source 3 means that in the case where there is water in alternative source 3, the water supply to the water intake line 4 comes from alternative source 3. The presence of water in alternative source 3 means that the container 5 is filled with water, for example, accumulated rain or melted snow water, or any other water. From tank 5, water enters tank 7 with the help of pump 6. If the water level in tank 7 is above the minimum, then the water is under pressure higher, than the pressure of the external water supply 1. Thus, the water to the line 4 of the water intake for consumption is supplied priority from an alternative water source 3. If the water level in the tank 7 is below the minimum, then the water is withdrawn to the line 4 of the water intake for consumption from the external water supply 1. At the same time, the water supply system functions as a flow switching control valve. The absence of a complex system for switching streams provides increased reliability of the system, thus solving the problem and achieving the technical result.
Система может содержать два и более альтернативных источника воды аналогичной конструкции. В этом случае линия 4 забора воды на вход подключена к трем источникам: внешнему водопроводу 1, альтернативному источнику 3 и дополнительному альтернативному источнику (на фигурах не представлен). В этом случае, наибольшее давление имеет альтернативный источник с большим уровнем воды в емкости 5. На линию 4 забора жидкости вода подается преимущественное из альтернативного источника с большим уровнем воды, в случае, если вода отсутствует в обоих альтернативных источниках, вода на линию 4 забора жидкости поступает из внешнего водопровода 1. The system may contain two or more alternative water sources of similar design. In this case, the input water line 4 is connected to three sources: an external water supply 1, an alternative source 3 and an additional alternative source (not shown in the figures). In this case, the alternative source with a high water level in the tank 5 has the highest pressure. Water is supplied to the liquid intake line 4 from an alternative source with a high water level, if water is not available in both alternative sources, water is supplied to the liquid intake line 4 comes from external water supply 1.
Дополнительно система водоснабжения может содержать средство очистки воды (на фигуре не представлено), которое устанавливается на линии 2 подачи воды из альтернативного источника после насоса 6 перед баком 7. Средство очистки воды может быть выполнено в виде, например, но, не ограничиваясь перечисленными вариантами, системы обратного осмоса, системы мембранной очистки воды и половолоконным модулем, системы механической предфильтрации, сорбционного фильтра, системы комбинированной очистки воды и т.п. В случае, если система водоснабжения в блоке альтернативного источника 3 содержит средство очистки воды, то вода из емкости 5 поступает сначала на насос 6, потом проходит через систему очистки воды и поступает в бак 7 и далее на линию 4 забора жидкости очищенной. Additionally, the water supply system may contain a water treatment facility (not shown in the figure), which is installed on the water supply line 2 from an alternative source after the pump 6 in front of the tank 7. The water treatment facility can be made in the form, for example, but not limited to the listed options, reverse osmosis systems, membrane water purification systems and hollow fiber modules, mechanical prefiltration systems, sorption filters, combined water purification systems, etc. If the water supply system in the alternative source unit 3 contains a water purification agent, then the water from the tank 5 first enters the pump 6, then passes through the water purification system and enters the tank 7 and then to the purified liquid intake line 4.
Дополнительно система водоснабжения может включать в себя редуктор давления (на фигуре не представлен), который устанавливается в точке подключения линии 4 забора воды к внешнему водопроводу 1. Редуктор давления снижает давление воды, поступающей от внешнего водопровода 1, таким образом, давление воды в баке 7 может быть пропорционально снижено, но при этом оставаться выше давления воды внешнего водопровода 1. Снижение давления воды в системе водоснабжения повышает безопасность работы системы и надежность. Дополнительно система может содержать линию промывки (на фигуре не представлена), которая на вход подключена к внешнему водопроводу 1, а на выход к емкости 5 альтернативного источника 3. Вода альтернативного источника (например, дождевая или талая) содержит примеси, которые могут быть причиной зарастанию системы водоснабжения. Кроме того, например, в случае засухи, вода в альтернативном источнике 3 может не быть длительное время, что приводит к пересыханию узлов системы. При наличии в системе есть линия промывки, емкость 5 альтернативного источника 3 периодически заполняется водой внешнего водопровода 1, которая поступает по линии промывки. Если емкость 5 заполнена водой, то система работает в рамках отличительных признаков. Как только в емкости 5 альтернативного источника 3 появляется вода, насос 6 подачи перекачивает ее в бак 7. Вода накаливается в баке 7 и, если уровень воды выше минимального, вода отбирается по линии 4 забора воды. При этом, поскольку вода проходит по всем узлам системы, предотвращается пересыхание узлов альтернативного источника 3. Таким образом, дополнительно повышается надежность системы. Additionally, the water supply system may include a pressure reducer (not shown in the figure), which is installed at the point of connection of the water intake line 4 to the external water supply 1. The pressure reducer reduces the pressure of the water coming from the external water supply 1, thus, the water pressure in the tank 7 can be proportionally reduced, but at the same time remain above the water pressure of the external water supply 1. Reducing the water pressure in the water supply system increases the safety of the system and reliability. Additionally, the system may contain a flushing line (not shown in the figure), which is connected to the external water supply 1 at the inlet, and to the alternative source tank 5 at the outlet 3. Alternative source water (for example, rain or melt) contains impurities that can cause water supply systems. In addition, for example, in the event of a drought, the water in the alternative source 3 may not be available for a long time, which leads to the drying of the system nodes. If there is a flushing line in the system, the container 5 of the alternative source 3 is periodically filled with water from the external water supply 1, which flows through the flushing line. If the container 5 is filled with water, then the system operates within the distinctive features. As soon as water appears in the container 5 of the alternative source 3, the supply pump 6 pumps it into the tank 7. The water heats up in the tank 7 and, if the water level is above the minimum, the water is taken from the water intake line 4. At the same time, since the water passes through all the nodes of the system, the drying of the nodes of the alternative source 3 is prevented. Thus, the reliability of the system is further improved.
