Description

No suction no negative pressure pressurized steady flow water supply equipment

technical field

The utility model relates to the technical field of water supply equipment, in particular to a water supply equipment with no suction lift, no negative pressure, pressurization and steady flow.

Background technique

At present, water supply to high-rise buildings or buildings in areas with unstable tap water pressure is generally achieved by connecting water supply equipment in series to the tap water pipe network for secondary water supply. However, the liquid level sensor used in the existing water supply equipment is a float type, and the work of this float type liquid level sensor is unstable, and the level of the liquid level cannot be accurately detected, especially in a container for tap water and water supply equipment. When there is no water or lack of water, an error signal is often sent, causing the water pump to run idly and easily burn out the water pump.

Utility model content

The technical problem to be solved by the utility model is to provide a non-negative pressure pressurized steady flow water supply device which can avoid the idling of the water pump when there is no water or lack of water in the container of the water supply device.

In order to solve the above technical problems, the utility model adopts the following technical scheme. The water supply equipment includes a container and an electric control cabinet. The container is provided with a vacuum suppressor, and a liquid level sensor is provided inside. The normal pressure water supply pipeline and the pressurized water supply pipeline connected in parallel are connected to the pipe; a check valve is connected in series on the normal pressure water supply pipeline, and a water pump and a check valve are connected in series on the pressurized water supply pipeline; A near-end pressure sensor is provided on the water supply pipe on the water inlet side of the water supply pipeline and a pressurized water supply pipeline, and a remote pressure sensor is provided on the water supply pipe on the outlet side of the normal pressure water supply pipeline and the pressurized water supply pipeline; The liquid level sensor, water pump, proximal pressure sensor and remote pressure sensor are electrically connected to the electric control cabinet; its structural features are: the liquid level sensor is a guide rod slider structure, and the guide rod with contacts is located in the container , The guide rod is provided with a slider that can slide up and down.

The pipe network with the above structure has no negative pressure pressurization and steady flow water supply equipment. Since the container is equipped with a liquid level sensor with a guide rod slider structure, the guide rod is located in the container, and the slider can only move up and down along the guide rod with the liquid level. , so the work is stable, the detection is accurate, it will not cause the water pump to run without water, and avoid the water pump from burning out.

In order to prevent damage to the single pressurized water supply pipeline from affecting the water supply or that the single pressurized water supply pipeline cannot meet the water supply requirements, the water supply equipment is equipped with two pressurized water supply pipelines.

Description of drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:

Accompanying drawing is the structural principle diagram of the utility model.

Detailed ways

The water supply equipment as shown in the accompanying drawings includes a container 1 and an electric control cabinet 2 . A vacuum suppressor 3 is provided on the container 1, and a liquid level sensor 4 is arranged in it. The liquid level sensor 4 is a guide rod slider structure, and a guide rod 10 with contacts is located in the container 1. Slider 11 for sliding. The container 1 is connected with a water inlet pipe 5 and a water supply pipe 6, the water inlet pipe 5 is connected with a gate valve 13, and the water supply pipe 6 is connected with a normal pressure water supply pipeline and two pressurized water supply pipelines in a parallel relationship; normal pressure water supply A one-way valve 7 and a gate valve 13 are connected in series on the pipeline, and a gate valve 13, a water pump 8, a one-way valve 7 and a gate valve 13 are connected in series on the pressurized water supply pipeline; A gate valve 13 and a proximal pressure sensor 9 are connected to the water supply pipe 6 on one side, and a remote pressure sensor 12 is connected to the water supply pipe 6 on the outlet side of the normal pressure water supply pipeline and the pressurized water supply pipeline. The liquid level sensor 4 , the water pump 8 , the proximal pressure sensor 9 and the remote pressure sensor 12 are electrically connected to the electric control cabinet 2 .

When in use, connect the water inlet pipe 5 and the water supply pipe 6 of the water supply equipment with the above-mentioned structure to the tap water pipe network and the user pipe network respectively. Water can be supplied to users through normal pressure water supply pipelines. When the water flow and water pressure do not reach the set value, the near-end pressure sensor 9 sends a signal to the electric control cabinet 2, and the electric control cabinet 2 starts the water pump 8 to realize water supply. When negative pressure is generated in 1, the vacuum suppressor 3 is automatically opened to communicate the interior of container 1 with the atmosphere, avoiding negative pressure on the tap water network, and at the same time, the water stored in container 1 replenishes the insufficient water intake. When the set low liquid level is set, the liquid level sensor 4 sends a signal to stop the water pump, so as to avoid the damage of the water pump due to no water idling. The remote pressure sensor 12 can detect the water pressure of the water supply at any time, send a signal to the electric control cabinet 2 according to the change of the water pressure, and control the speed of the water pump through the frequency change of the frequency converter in the electric control cabinet 2, so as to realize optimized water supply. Electric energy can also be utilized more rationally.
