One-way pressure supplementing tower used for water conveying system

Abstract

The invention discloses a one-way pressure supplementing tower used for a water conveying system. The one-way pressure supplementing tower comprises a pressure supplementing tower body and a water supplementing pipe, wherein the pressure supplementing tower body is arranged above a water conveying pipe and is provided with a water storage tank, and the water supplementing pipe runs through the water storage tank and the water conveying pipe; the water supplementing pipe is provided with a check valve; an automatic water supplementing system comprises a water inlet pipe, and a hydraulic valve which controls the opening and closing of the water inlet pipe according to the water level of the water storage tank and is provided with a floating ball device; an upper port of the water inlet pipe is connected with the water storage tank, a lower port of the water inlet pipe is connected on a water supplementing pipe arranged between the check valve and a lower port of the water supplementing pipe; and the floating ball device is arranged in the water storage tank, the hydraulic valve is arranged on the water inlet pipe. As the water storage tank of the pressure supplementing tower is arranged above the water conveying pipe, when negative pressure exists in the water conveying pipe, water in the water storage tank has certain potential energy relative to the water in the water conveying pipe, so that water can be supplemented to the water conveying pipe in the negative pressure state automatically, further the one-way pressure supplementing tower plays the role of equalizing pressure to avoid the damage of pipe explosion due to negative pressure of the conventional water conveying system.

Description

technical field [0001] The invention relates to the field of pressure supplementation equipment for a water delivery system, in particular to a one-way pressure supplement tower for a water delivery system. Background technique [0002] At present, in solving the problem of long-distance water delivery, most of the methods such as attached figure 1 The water delivery system shown is for long-distance water delivery: booster pumps 1 and water suction wells 2 in several booster pump stations are arranged alternately and in series on the water delivery pipe; The water pipe is divided into multiple pipe sections so that the failure will not affect the safety of other pipe sections; however, due to the installation of the water suction well, the residual pressure of the upper booster pump station is released at the water suction well, which is not very good The utilization of residual pressure causes waste of energy. [0003] In order to overcome the above defects, it is possib...

But this also brings potential danger. If a booster pump station pumps water and loses power, a large negative pressure will be generated along the water pipe behind the pump, causing the pipe to burst. Even if the addition of a single automatic intake and exhaust valve is sufficient There is no requirement for flat pressure, so a pressure supplement device that can be connected in series between two booster pump stations for flat pressure is needed to avoid hazards
