The sensor is connected with the controller, and the electric valves in the adapter are connected with the controller. The steady flow compensation tank of the forced superimposed non-negative pressure water supply equipment is connected in series and the tap water can be used to utilize 100% of the original pressure. The steady flow compensation tank is a fully sealed pressure vessel and is completely isolated from the outside world, which can completely eliminate the damage caused by the contact between tap water and the atmosphere. The automatic pressure regulating adapter makes full use of the pressure of the tap water pipe network to achieve triple overlapping pressure effect and save energy.

Description

Forced laminated non-negative pressure water supply equipment

technical field

The utility model belongs to water supply equipment, in particular to non-negative pressure water supply equipment which can utilize the original pressure of tap water.

Background technique

In order to solve the problem of water supply on higher floors in areas with low water pressure in urban tap water pipe networks, people have used many methods. The traditional method is to transfer river water to pools or tanks and then use water supply equipment to pressurize it and send it to the user pipe network. These methods are not only wasteful The pressure of the original tap water is reduced and it is easy to cause secondary pollution. In recent years, non-negative pressure water supply equipment has begun to appear. The steady flow compensation tank is connected in series with the tap water to pressurize the water supply. Although the original pressure of the tap water can be used to release the pressure through atmospheric contact, In order to eliminate the negative pressure, there is still the possibility of secondary pollution.

Utility model content

In order to overcome the shortcomings of the existing non-negative pressure water supply equipment, which utilizes insufficient tap water pressure and may cause secondary pollution, the purpose of this utility model is to provide a forced superimposed non-negative pressure water supply equipment, the forced superimposed non-negative pressure water supply equipment The equipment can not only make full use of the original pressure of tap water, but also effectively prevent secondary pollution caused by contact with the atmosphere.

The technical solution adopted by the utility model to solve the technical problem is: a forced superimposed non-negative pressure water supply equipment, which is composed of a steady flow compensation tank, a water pump, a control cabinet, a pressure sensor, etc. It is characterized by: at the bottom of the steady flow compensation tank Equipped with a non-negative pressure internal water source pipe, which is connected to the original steady flow compensation tank downpipe with an automatic pressure regulating adapter composed of electric valve A, electric valve B, and electric valve C. The normal pressure outlet pipe of the adapter is connected to the user pipe The booster outlet pipe is connected to the booster water pump, the water level sensor in the compensation tank is connected to the controller, and the electric valves in the adapter are connected to the controller.

In the automatic pressure regulating adapter, the electric valve A is connected between the non-negative pressure inner water source pipe and the water pipe of the steady flow compensation tank, the electric valve B is connected between the water pipe of the steady flow compensation tank and the normal pressure outlet pipe, and the electric valve C is connected between the downpipe of the steady flow compensation tank and the pressurized outlet pipe.

The beneficial effect of the utility model is that the steady flow compensation tank of the forced superimposed non-negative pressure water supply equipment is connected in series and the tap water can be used to make use of 100% of the original pressure, and the steady flow compensation tank is a fully sealed pressure vessel and can be completely isolated from the outside world. Eliminate secondary pollution caused by contact between tap water and the atmosphere, and the automatic pressure-regulating adapter makes full use of the pressure of the tap water pipe network to achieve a triple-overlapping effect to save energy.
