Direct non-negative pressure steady-flow water supply equipment

Abstract

The invention provides a direct non-negative pressure steady-flow water supply equipment. The direct non-negative pressure steady-flow water supply equipment comprises a non-negative pressure steady flow tank, a negative pressure eliminator, a water pump and a control cabinet, wherein an internal seal head is arranged in the non-negative pressure steady flow tank; the non-negative pressure steady flow tank is divided into a steady flow chamber and an adjusting chamber; the steady flow chamber is connected with a water inlet pipe; the negative pressure eliminator is mounted at the upper part of the steady flow chamber; a water level sensor and a water drain valve are arranged at the bottom of the steady flow chamber; flange connection is adopted in the adjusting chamber; a rubber expansion airbag is arranged in the adjusting chamber; and a pressure gauge is mounted at the upper part of the adjusting chamber. The direct non-negative pressure steady-flow water supply equipment provided by the invention has the following advantages that: because the water supply equipment is directly connected with a pipe network in series to supply water without generating negative pressure, the energy saving effect can be reached through sufficient utilization of pipe network pressure and less space usage, lest investment and stable water supply pressure are obtained; meanwhile, the rubber expansion airbag is adopted in the adjusting chamber of the non-negative pressure steady flow tank, the gas and water are separated to avoid problems of gas loss and gas addition caused by direct contact between the gas and the water; moreover, because flange connection is adopted in the adjusting chamber, the maintenance is convenient.

Description

1. Technical field [0001] The invention relates to a water supply device, in particular to a direct non-negative pressure steady flow water supply device connected in series on a pipe network. 2. Background technology [0002] Most of the current water supply equipment is pressurized by water pumps that draw water from pools and water tanks. It occupies a large area and requires high investment. Moreover, it cannot use the pressure of the pipe network, and there is a waste of energy. In addition, the water quality is seriously polluted, and some of them use direct non-load Pressure water supply equipment, but the direct non-negative pressure water supply equipment of the prior art is to set the stabilizing tank and the regulating tank separately, which can not achieve the optimal effect in terms of investment, land occupation, installation, etc. 3. Contents of the invention [0003] In view of the deficiencies of the prior art above, the present invention provides a direct...

[0002] Most of the current water supply equipment is pressurized by water pumps that draw water from pools and water tanks. It occupies a large area and requires high investment. Moreover, it cannot use the pressure of the pipe network, and there is a waste of energy. In addition, the water quality is seriously polluted, and some of them use direct non-load Pressure water supply equipment, but the direct non-negative pressure water supply equipment of the prior art is to set the stabilizing tank and the regulating tank separately, which cannot achieve the best results in terms of investment, land occupation, installation, etc.
