Water supply equipment integrating vacuum inhibition and reverse flow compensation

Abstract

The invention discloses water supply equipment integrating vacuum inhibition and reverse flow compensation. The water supply equipment comprises a steady flow compensation tank. A steady flow tank consists of two cavity bodies and is divided into a prepressing cavity and the steady flow compensation tank, wherein the prepressing cavity is connected with a pressure stabilization energy accumulator; a prepressing self-balancing device is mounted at the bottom of the prepressing cavity; a reverse flow compensator is arranged below the steady flow compensation tank; the steady flow compensation tank is connected with the reverse flow compensator by a reverse flow compensation pipe; and the reverse flow compensator is connected with a user pipeline by a small-flow pressure maintaining pipe. A vacuum inhibitor is arranged in the steady flow compensation tank and close to a top wall; an outlet of the vacuum inhibitor is connected with the prepressing cavity; and when water enters the steady flow compensation tank, the vacuum inhibitor exhausts air in the tank into the prepressing cavity. The equipment solves the problems of pollution in the steady flow tank and external pollution of the outside air to tap water, and has a reverse flow compensation function.

Description

technical field [0001] The invention relates to a water supply equipment, in particular to a water supply equipment combined with vacuum suppression and backflow compensation. Background technique [0002] With the rapid development of my country's economic construction, the scale of construction is expanding day by day, land resources are becoming more and more precious, and high-rise buildings are springing up like mushrooms after rain. In the prosperous areas of the city, the height of buildings is far beyond the scope of the municipal water supply pressure. In order to meet the needs of users, the municipal water source must be pressurized twice, so the secondary pressurized water supply has become a very common design in today's building water supply design. Phenomenon. At present, the common secondary pressurized water supply equipment in China is pipe network superimposed water supply equipment, which directly uses the municipal pipe network as the water source, p...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a water supply equipment that combines vacuum suppression and countercurrent compensation. This equipment overcomes the internal pollution of the steady flow tank and the external pollution of tap water by the outside air. At the same time, the water supply in the municipal pipe network is insufficient. , it has the function of countercurrent compensation, and can still provide basic water supply to the user end when the municipal pipe network cannot supply water to the user end
