Description

Energy saving water supply equipment

technical field

The utility model relates to an energy-saving water supply equipment.

Background technique

At present, in the secondary pressurized water supply equipment, there are generally three types according to the water supply method: 1. Non-negative pressure water supply equipment that directly utilizes the residual pressure of the municipal pipe network. 2. Generally, the water supply equipment (including the type with air pressure tank) is equipped with a water tank or a pool to pressurize and supply water through a booster pump. 3. Box-type non-negative pressure pumping station. Among the two water supply methods 1 and 2, the water supply method is single, and the non-negative pressure water supply equipment will stop running when the municipal pipe network stops water, which has defects in the continuity of water supply; a separate water tank or pool is pressurized to supply water through a booster pump , and did not make use of the surplus pressure of the municipal pipe network, which is not good in terms of energy saving and environmental protection; most of the third type of water tank type non-negative pressure water supply equipment is to install the non-negative pressure water supply equipment in the water tank, and does not use the municipal pipe network The negative pressure water supply equipment of residual pressure water supply is used comprehensively with the common water supply method of water tank or pool.

Contents of the invention

The purpose of the utility model is to provide energy-saving, environment-friendly, convenient maintenance and installation, and energy-saving water supply equipment with good water supply continuity.

The energy-saving water supply equipment of the utility model includes municipal water inlet valve, non-negative pressure regulator, negative pressure eliminator, water collection pipe, booster pump, diaphragm type air pressure tank, electric contact pressure gauge, remote transmission pressure gauge, voltage stabilizer , the main water outlet pipe and the control cabinet, the municipal water inlet valve is connected to the non-negative pressure regulator through the non-negative pressure regulator inlet pipe, and the non-negative pressure regulator inlet pipe is equipped with an electric contact pressure gauge and an electric water inlet valve. The pressure regulator is connected to the main water outlet pipe through the water collection pipe and the booster pump. There is also an auxiliary pump between the water collection pipe and the main water outlet pipe. A balance adjustment pipe is installed between the main water outlet pipe and the non-negative pressure regulator. Return water solenoid valve, a voltage stabilizer, a remote pressure gauge and a diaphragm-type air tank are installed on the main outlet pipe, the water tank is connected to the municipal water inlet valve through the water tank inlet pipe, and a remote control float valve is installed on the water tank inlet pipe without negative pressure adjustment The water collecting pipe of the device is connected with the water tank through the water outlet electric valve and the water outlet gate valve, and the water tank is provided with a discharge valve and an overflow port.

The working principle of the energy-saving water supply equipment of the utility model is: the municipal water supply enters the water tank through the water inlet pipe of the water tank and the remote control float valve, and when the water is full, the remote control float valve automatically closes the water intake to complete the water supply of the water tank; at the same time, the municipal water supply passes through the non-negative pressure regulator The water inlet pipe and the water inlet electric valve enter the non-negative pressure regulator, and the negative pressure eliminator adjusts the internal and external pressure balance of the non-negative pressure regulator, allowing water to fill the non-negative pressure regulator for normal delivery. When the municipal flow meets the working requirements of the non-negative pressure system (automatic detection by the control system), the water outlet electric valve of the water tank is in the closed state, and the water inlet electric valve is in the open state. No negative pressure water supply. When the water supply of the pipe network is insufficient, the water flow in the municipal water inlet pipe is empty, or the air pressure in the non-negative pressure regulator is lower than the atmospheric pressure, the water level in the non-negative pressure regulator will drop, and the negative pressure eliminator will be put into work to make the non-negative pressure regulator Atmospheric pressure is maintained inside. At this time, the return water solenoid valve on the balance regulating pipe is opened, and part of the high pressure is returned to the non-negative pressure regulator for supplementary flow adjustment, so as not to generate negative pressure on the municipal pipe network. The above process is completed in a short period of time. If there is no negative pressure system in a short period of time and the system does not resume operation, an electric contact pressure gauge is installed on the water inlet pipe of the non-negative pressure regulator. When it is detected that the water inlet pipe of the municipal pipe network is short of water, the pressure decreases To a certain extent (adjustable), at this time the system automatically instructs the non-negative pressure regulator to close the water inlet electric valve, the water tank outlet water electric valve to open, and switch to the ordinary frequency conversion constant pressure system to run. When the electric contact pressure gauge detects that the pressure of the municipal pipe meets the When the non-negative pressure system is working, the water outlet electric valve of the water tank is automatically closed, and the water inlet electric valve of the non-negative pressure regulator is automatically opened to resume the operation of the non-negative pressure system, realizing automatic switching between the two systems. When the water consumption is low at night, the equipment is equipped with a small-flow auxiliary pump, which works with a diaphragm-type pressure tank.

In addition to the advantages of non-negative pressure water supply equipment, the energy-saving water supply equipment of the present utility model also has:

1. Ensure the continuity of water supply and make up for the defects of ordinary non-negative pressure water supply equipment in the aspect of water supply continuity;

2. It is more energy-saving and environmentally friendly than ordinary water supply equipment (including the type with air pressure tank) that is equipped with a water tank or pool to pressurize water supply through a booster pump;

3. The equipment has two systems of non-negative pressure control and ordinary frequency conversion booster control, and can be automatically switched between the two systems.
