Background technique

The applicant’s previous patent application 200620126506.8 discloses an "integrated intelligent silent pipe network superimposed water supply equipment", including: a fully sealed pressure buffer tank with a water inlet connected to a tap water pipe, and a negative pressure tank at the top of the pressure buffer tank. Sensor and exhaust device, the bottom end is provided with a water outlet pipe; the connecting pipe connecting the water outlet of the pressure buffer tank and the water pipe at the user end is connected, and the connecting pipe is connected in parallel by two sets of booster pump pipelines and a set of bypass pipelines, The booster pump in the booster water pump pipeline is placed in the steady flow sleeve, the constant pressure tank with an air bag is connected to the bypass pipeline, and the outlet pipe of the fully sealed pressure buffer tank and the water pipe at the user end are connected separately; the bypass at the user end A water outlet pressure sensor arranged on the pipeline; a programmable frequency conversion controller connected to the above-mentioned exhaust device, negative pressure sensor, and booster pump signals respectively. There are still some deficiencies in this equipment, which are reflected in: the volume of the constant pressure buffer tank in the equipment is small, the tap water pressure is high and the flow is sufficient during operation, the applicable limitations are large, and it is not suitable for use in the water supply environment where the tap water flow and pressure are extremely unstable. ; Secondly, the electrical control part of the equipment is cumbersome to connect and occupies a relatively large area.

Contents of the invention

The utility model is just to overcome the above-mentioned deficiencies, and provides an integrated intelligent box-type pipe network superimposed water supply equipment with unlimited tap water flow and pressure, which greatly improves the scope of application of the equipment. The main innovation lies in the use of tap water inlet and The two-way water inlet of the water tank is self-adjusting and controlled. When the tap water pressure is high at the low peak of water consumption, the tap water inlet method is automatically used to realize the pipe network superimposed pressure (no negative pressure) water supply method through the municipal pipe network protector. If the tap water pressure is at the peak of water consumption When the water is low or the water is cut off, the water from the water tank is automatically used to realize the frequency conversion and constant pressure water supply of the water tank. The large-capacity water tank ensures that the user can safely pass the peak period; when the tap water pressure returns to the set value, it will automatically switch to the energy-saving pipe network stack again. pressure (no negative pressure water supply state). Specifically, it is implemented in this way: the integrated intelligent box-type pipe network superimposed water supply equipment includes the water inlet pipe connected to the tap water pipe network, and the water inlet pipe is equipped with a water inlet pressure sensor, a water inlet electric valve, and a water inlet check valve. , the inlet pipe behind the check valve is equipped with a municipal pipe network protector; the outlet pipe connected to the water pipe at the user end is equipped with an outlet water pressure sensor; two sets of booster pump connecting pipes between the inlet pipe and the outlet pipe The booster pump in the booster water pump pipeline is placed in the steady flow sleeve. There is a water inlet butterfly valve in front of the booster water pump, and a pump outlet check valve and a water outlet butterfly valve are installed in turn behind the booster water pump; The tank is connected to the junction of two sets of booster pumps connecting pipelines and outlet pipes; the programmable frequency conversion controller is connected to the water inlet pressure sensor, water outlet force sensor, each valve, and the booster pump signal respectively. The water pump connection pipeline, constant pressure tank, and programmable frequency conversion controller are fixedly installed in the electric power room on the base. There is a water tank on the base. Between the water inlet check valves, the water outlet pipeline of the water tank is connected to the front end of the connecting pipeline of the two sets of booster pumps, and the water tank water inlet check valve is installed on the water tank outlet pipeline. The return valve signal is connected to the programmable frequency conversion controller.

A liquid level controller is arranged on the water tank of the utility model, and an overflow pipe and a floating ball protection device are arranged at the bottom of one side of the water tank.

Tap water enters the water tank through the water inlet pipe, water inlet electric valve, and float control valve. After the pressure is automatically compared by the check valve in front of the pump and the check valve, it is pressurized by the built-in booster pump through the pump outlet check valve and butterfly valve. The surge tank and outlet pipe are delivered to the user for use. The automatic conversion control between the pipe network superimposed pressure water supply and the water tank constant pressure water supply of the whole set of equipment is completed by the water inlet pressure sensor, the municipal pipe network protector, the water outlet pressure sensor, the liquid level control controller and the PLC in the electrical control room.

Pipe network superimposed pressure (no negative pressure) water supply implementation process: the equipment is in the water supply process (the water tank is full and the float is automatically closed), the pressure sensor detects the water inlet pressure of the tap water in real time, and transmits the signal to the frequency conversion control room. When the tap water pressure is greater than a certain value (PLC setting), the water inlet electric valve is automatically opened, the tap water automatically enters the municipal pipe network protector, and the tap water inlet check valve automatically opens (the pressure is greater than the water tank inlet check valve ), after the frequency conversion operation of the built-in submersible pump, it supplies water normally with a constant pressure.

The implementation process of box-type constant pressure water supply: when the equipment is in a certain peak water consumption period, when the pressure sensor detects that the tap water pressure is unstable or lower than the set value for a certain period of time, the water inlet electric valve is automatically closed, and the municipal pipe network The protector also automatically eliminates the negative pressure. At this time, the water inlet check valve of the water tank is automatically opened (the pressure is higher than the tap water inlet check valve). After the built-in submersible pump is operated by frequency conversion, water is supplied normally with a constant pressure. When the tap water pressure returns to the set value again, it will automatically switch to the pipe network superimposed pressure (no negative pressure) water supply mode; this mode of operation not only avoids the generation of negative pressure, but also ensures the continuity of water supply. This function cannot be achieved by the original non-negative pressure water supply equipment.

The implementation process of the superimposed pressure of the outlet water frequency conversion constant pressure pipe network: when the outlet water pressure is lower than the pressure required by the user, the tap water will automatically enter the pump stabilization sleeve through the check valve, and the pressure will pass the signal to the frequency conversion control room through the pressure sensor, and then The frequency converter commands the submersible pump to supply water with variable frequency and constant pressure. When the original tap water pressure is higher than the pressure required by the user, the frequency conversion control room will stop the work of the submersible pump according to the pressure signal of the water inlet pipe provided by the pressure sensor, and the equipment is in a dormant energy-saving state. At this time, the water is passed through the check by the water inlet electric valve. The valve directly enters the outlet pipe to supply water to the user.

The implementation of the float fault alarm function: when the float leaks, the overflowing water will first reach the float protector at the bottom through the overflow pipe, and the liquid level sensor in the protector will alarm through the PLC peak, and timely Inform the maintenance personnel to carry out maintenance, which effectively avoids the waste of water resources.

The base of the utility model is additionally provided with a disinfection filter room, which is built with a water treatment and disinfection machine and a precision filter. The pipeline of the water treatment and disinfection machine is connected to the end of the connecting pipeline of the booster pump. A solenoid valve is installed, the signal of the solenoid valve is connected to the programmable frequency conversion controller, and the end pipeline of the precision filter connected to the water treatment and disinfection machine is connected to the water tank. The implementation process of water quality disinfection and filtration in the water tank: the disinfection and filtration of water quality are set by the PLC through the time (generally set the low peak of water use in the early morning), and the return water solenoid valve is opened regularly in a certain period of time, and then flows through the water for water treatment and disinfection machine and precision filter. Disinfection time is set according to need. In order to ensure the freshness of the water, the function of forcing the release of the superimposed pressure of the pipe network without negative pressure is specially added. When the running time of the superimposed pipe network without negative pressure exceeds 8 hours in a row, the PLC will force the water inlet electric valve to be closed, and the equipment will operate in the water supply mode of the water tank. The running time is controlled by the liquid level controller. When the liquid level reaches the low level, it will switch to the state of superimposed water supply of the pipe network, and at the same time replenish water to the water tank again, so as to ensure the freshness and purity of the water in the water tank.

The implementation process of the remote monitoring operation of the utility model: according to the actual situation of the user, set the working pressure, shutdown pressure, automatic, manual, startup, shutdown, fault alarm status, etc. of the equipment in the frequency conversion control room. It can be directly controlled by touch on the LCD screen, or it can be connected to the computer in the property office through a network cable, and the computer can remotely monitor and operate the device.

On the basis of the original integrated structure, the utility model puts the water pump in the steady flow sleeve in the water tank, and realizes the function of pipe network superposition (no negative pressure) through the municipal pipe network protector and the water tank water inlet check valve; through Water inlet electric valve, check valve and liquid level controller are used to realize the frequency conversion and constant pressure water supply function of the water tank; the outlet pipe is connected with the air bag in the constant pressure tank, which can eliminate the water hammer phenomenon in addition to the small flow water supply; add a floating ball protection device Effectively avoid the waste of water resources; add water tank water treatment and disinfection machines and precision filters to ensure fresh and pure water quality; at the same time, implement remote monitoring and man-machine dialogue through program settings.

The utility model expands the application field of the pipe network superimposed non-negative pressure water supply equipment. The equipment is fully built-in, which facilitates the operation of the equipment and truly realizes the "fool" type. The user only needs to connect the water inlet and outlet of the equipment and then plug in It can run after power on; completely overcome the pollution of water quality and the waste of water resources, and improve the quality of water supply; remote monitoring, man-machine dialogue, thus truly realizing the fully automatic integrated water supply equipment.
