The high-pressure water enters the water bag of the multi-function tank after passing through the water outlet main pipe and the two-position three-way solenoid valve. Go back to the water outlet main pipe to supply water to the user, so as to achieve the function of the pressure tank. When the system needs to replenish water after the tap water inlet pressure is reduced, the two-position three-way solenoid valve is energized, and the ports (14) and (16) are closed, and the port (14) and (16) are closed. 14) and (15) are connected. At this time, the low-pressure water in the multifunctional tank flows to the main water inlet through the two-position three-way solenoid valve, and then is pressurized by the pump into the user's pipe network system to meet the user's water requirements. At this time The multi-functional tank has become the function of a non-negative pressure stabilizing tank, so that the equipment can not only realize the functions of stabilizing the voltage and flow, but also reduce the area occupied by the equipment and the production cost, and at the same time facilitate transportation and installation, and reduce the labor intensity of workers .

There is a water bag 6, and an inflation port 7 is also opened on the multifunctional tank 2, the outlet 8 of the multifunctional tank 2 is connected with the port 14 of the two-position three-way solenoid valve 3, and the port 15 of the two-position three-way solenoid valve 3 is connected with the inlet The water main pipe 9 is connected, the water main pipe 9 is respectively connected with the inlet 10 of the water pump 1 and the one-way device 5, the other end of the one-way device 5 is connected with the tap water inlet 11, and the water outlet 12 of the water pump 1 is connected with the water outlet main pipe 13 through a valve group , The water outlet main pipe 13 is also connected with the port 16 of the two-position three-way solenoid valve 3 simultaneously.
本新型利用两位三通电磁阀3的开关状态，来达到多功能罐2发挥不同的功能作用，当自来水进正常时两位三通电磁阀3的口16和口14接通，高压水流向多功能罐2，由于在多能罐2的罐壁和水囊6之间充有压缩空气，当水泵1休眠时多功能罐2中的高压水通过两位三通电磁阀3反回到出水总管13向用户供水，以此减少泵的启动次数达到节能的目的，当自来水进水压力不足这时两位三通电磁阀3得电关闭，这时两位三通电磁阀3的口14和口15连通，口16和口14关闭，水通过进水总管9向用户供水，当多功能罐2中的压力降低时水泵1启动加压向用户供水，以此满足用户的用水要求，当自来水压力恢复正常后系统有返回到原来的工做状态，以此循环，同时由于在自来水进口11处安装有单向装置5，从而保证多功能罐2中的高压水不会回流到自来水主管网中，达到自来水供水安全的目的。This new model utilizes the switching state of the two-position three-way solenoid valve 3 to achieve different functions of the multi-functional tank 2. When the tap water enters normally, the port 16 and port 14 of the two-position three-way solenoid valve 3 are connected, and the high-pressure water flows Multifunctional tank 2, since the tank wall of the multifunctional tank 2 and the water bladder 6 are filled with compressed air, when the water pump 1 is dormant, the high-pressure water in the multifunctional tank 2 returns to the water outlet through the two-position three-way solenoid valve 3 The main pipe 13 supplies water to the user, so as to reduce the number of starts of the pump to achieve the purpose of energy saving. When the tap water inlet pressure is insufficient, the two-position three-way solenoid valve 3 is powered off. At this time, the port 14 of the two-position three-way solenoid valve 3 and Port 15 is connected, port 16 and port 14 are closed, and water is supplied to the user through the water inlet main pipe 9. When the pressure in the multifunctional tank 2 drops, the water pump 1 starts to pressurize and supply water to the user, so as to meet the water demand of the user. When tap water After the pressure returns to normal, the system returns to the original working state and circulates in this way. At the same time, because the one-way device 5 is installed at the tap water inlet 11, it is ensured that the high-pressure water in the multi-function tank 2 will not flow back into the tap water main network. , To achieve the purpose of water supply safety.
