The invention discloses constant-pressure variable integrated no-negative-pressure
water supply equipment, comprising a municipal
tap water pipe network, a medium and
high pressure flow-stabilizing compensator, a low-pressure flow-stabilizing compensator and a user
pipe network, wherein the medium and
high pressure flow-stabilizing compensator consists of two parts, i.e. a middle-pressure
water storage cavity and a high-pressure
water storage cavity; and the municipal
tap water pipe network is connected into the middle-pressure
water storage cavity which is communicated with the low-pressure flow-stabilizing compensator and the user pipe network by pipelines. The
water supply equipment is mainly used for realizing continuous
water supply when the water supply amount of the municipal
tap water pipe network can not meet the
water consumption peak requirement on the production and life. The water supply equipment is provided with two sets of water storage devices, namely the medium and
high pressure flow-stabilizing compensator and the low-pressure flow-stabilizing compensator, and when the water supply amount of the municipal tap
water pipe network is less than the amount of the
water consumption peak of residential quarters, the medium and high pressure flow-stabilizing compensator and the low-pressure flow-stabilizing compensator can be used as reserved
water resources to be supplied to the user pipe network, so that the normal
water consumption of users in the quarters is ensured.
