Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

Referring to Figures 1-2, this embodiment adopts the following technical solutions: non-negative pressure water supply equipment, including intelligent control cabinet 1, steady flow tank body 2, all stainless steel pump 3, wafer check valve 4, wafer check valve Butterfly valve 5, water inlet main pipe 6, drain valve 7, water outlet main pipe 8, bypass pipe and inlet pressure tank 9, steady flow tank body 2 is connected with water inlet main pipe 6, and water inlet main pipe 6 passes through wafer check valve 4 , The clip-on butterfly valve 5 is connected with the all stainless steel pump 3, the all stainless steel pump 3 is connected with the water outlet main pipe 8, and the water outlet main pipe 8 is provided with a drain valve 7, and the water outlet main pipe 8 is also connected with a plurality of bypass pipes, and the inlet air pressure The tank 9 is connected with the water inlet main pipe 6, and the intelligent control cabinet 1 is connected with the imported air pressure tank 9 and the all stainless steel pump 3.

It should be noted that the tank body 2 of the surge tank is a non-negative pressure surge tank.

It should be noted that the intelligent control cabinet 1 is a microcomputer frequency conversion control cabinet.

In addition, the intelligent control cabinet 1 is also connected with a pressure sensor, which is set in the water outlet main pipe 8 for monitoring the water pressure.

The working principle of this specific embodiment: when the equipment is normally put into use, the water in the municipal pipe network enters the non-negative pressure stabilizing tank, and the air in the tank flows out from the exhaust valve in large quantities. Float, drive the plug to the closed position, slowly close the exhaust port, stop the exhaust, and prevent water from flowing out. When the water flow in the steady flow tank is conveyed normally, if a small amount of air accumulates in the valve to a certain extent, the water level in the valve will drop , the floating ball drops accordingly, and the air is discharged from the vent hole at this time; during the normal operation of the equipment, when the water supply of the municipal pipe network is insufficient, the water in the municipal water inlet pipe is empty, or the water pressure in the steady flow tank is lower than the atmospheric pressure , the water level in the stabilizing tank drops, and the floating ball drops accordingly, driving the plug to open and inhaling air to keep the atmospheric pressure in the stabilizing tank, so as not to generate negative pressure on the municipal pipe network.

When the pressure in the municipal pipe network is lower than the set pressure required by the user, the water pump will be adjusted by frequency conversion to ensure that the pressure of the user pipe network meets the user's water requirements. The higher the water pressure of the municipal pipe network, the lower the speed of the pump, and the municipal pipe The lower the network water pressure, the higher the speed of the pump. When the water supply pressure of the municipal pipe network meets the user's requirements, the equipment will automatically stop working, and the water in the municipal pipe network will be directly supplied to the user through the bypass pipe; when the municipal pipe network stops water, The water level in the steady flow tank drops gradually. When it drops to the minimum water level, the liquid level gauge on the long steady flow tank sends a shutdown signal, and the equipment automatically stops running and displays a water shortage protection signal. When the power grid fails, the equipment shuts down, and the water in the municipal pipe network is directly supplied to the user from the equipment bypass pipe.

This specific implementation mode does not need to build pools and water tanks, the basic investment is small, green and environmentally friendly, fully enclosed, no pollution, no secondary pollution, water saving, use of the original pipe network water pressure, small pump operating power, more energy saving, no negative pressure Pipe network superimposition, frequency conversion control, energy saving of more than 50%, simple and compact structure, high space utilization rate, small footprint, short construction period and easy installation.
