Description

New distributed pressure water supply device

Technical field:

The utility model relates to a water supply device, in particular to a novel distributed pressure water supply device.

Background technique

The conventional distributed water supply system adopts the pressure tank of the pipe network system for water supply, because the pressure tank water supply system of the pipe network only plays the role of stabilizing the pressure and supplying a small amount of water, and the water supply capacity is only about 20% of the volume of the pressure tank; When there is water, all the water in the pressure storage tank will be supplied to downstream users. The water supply capacity is poor, which affects the water consumption of users; at the same time, when there is water from the upstream, the water pump starts frequently, which not only affects the service life of the water pump, but also produces noise that affects the surrounding environment. environment.

Utility model content:

The purpose of the utility model is to provide a novel distributed pressure water supply device which improves the water replenishment capacity of the pressure tank.

The utility model is implemented by the following technical solutions: a new distributed pressure water supply device, which includes a pressure tank and a water pump and an air pump arranged outside the pressure tank, a liquid level gauge is vertically arranged inside the pressure tank, The top of the tank is provided with a pressure sensor and an air filling port, a water inlet and an exhaust valve communicating with the inside of the pressure tank. The probe of the pressure sensor is placed inside the pressure tank, and the bottom of the pressure tank is provided The water outlet connected to the inside of the pressure tank; the water pump communicates with the water inlet through the water pipeline, and the gas outlet of the air pump communicates with the gas filling port through the gas pipeline; the liquid level gauge is respectively connected with the The water pump is electrically connected to the exhaust valve, and the pressure sensors are respectively electrically connected to the water pump and the air pump.

The utility model has the advantages of simple structure and convenient maintenance, and is suitable for distributed water supply systems; it improves the water supply capacity of the pressure tank, and when the upstream water flow is interrupted, the water supply can reach 70% of the volume of the pressure tank, reducing the number of starts of the water pump. Extend the service life of the water pump, avoid affecting the surrounding environment, and ensure the water supply to downstream users.

Detailed ways:

As shown in Figure 1, the new distributed pressure water supply device includes a pressure tank 1 and a water pump 2 and an air pump 3 arranged outside the pressure tank 1, and a liquid level gauge 4 is vertically arranged inside the pressure tank 1. The lower limit of the water level is set at the inner bottom of the pressure tank 1, and the upper limit of the water level of the liquid level gauge 4 is set at half of the height of the pressure tank 1; Port 6, water inlet 7 and exhaust valve 11, the probe of the pressure sensor 5 is placed inside the pressure tank 1, and the bottom of the pressure tank 1 is provided with a water outlet 8 connected to the inside of the pressure tank 1, and the water outlet 8 is connected to the user pipe network The water pump 2 communicates with the water inlet 7 through the water delivery pipeline 9, and the gas outlet of the air pump 3 communicates with the gas filling port 6 through the gas delivery pipeline 10; the liquid level gauge 4 is electrically connected with the water pump 2 and the exhaust valve 11 respectively, and the pressure sensor 5 are electrically connected to the water pump 2 and the air pump 3 respectively.

Working principle: When the water level drops to the lower limit set by the liquid level gauge 4, the liquid level gauge 4 sends out a signal, the exhaust valve 11 is opened, the pressure tank 1 is connected to the outside world, the water pump 2 is started, and water is pumped into the pressure tank 1; When the water level rose to the upper limit of the water level set by the liquid level gauge 4, the liquid level gauge 4 sent a signal to close the exhaust valve 11. At this time, the pressure tank 1 was closed, and the water pump 2 continued to pump water to the inside of the pressure tank 1 and build up pressure. With the injection of water, the pressure inside the pressure tank 1 gradually rises. When the upper limit pressure set by the pressure sensor 5 is reached, the pressure sensor 5 sends out a signal, the water pump 2 stops working, and the water storage work is completed; as the user's water consumption increases, The amount of water in the pressure tank 1 decreases, and the pressure in the pressure tank 1 gradually decreases. When the pressure in the pressure tank 1 is lower than the lower limit pressure value set by the pressure sensor 5, the pressure sensor 5 sends out a signal, and the air pump 3 starts to increase the pressure. Gas is added to the tank 1, and when the pressure in the pressure tank 1 rises to the highest pressure value, the air pump 3 stops working; as the user uses water, the air pump 3 circulates until the water level drops to the lowest value, completing a water supply cycle.
