Integrated box-type two-way compensation non-negative pressure water supply equipment

Abstract

The invention discloses integrated tank type two-way compensation non-negative-pressure water supply equipment. The integrated tank type two-way compensation non-negative-pressure water supply equipment comprises a flow controller, a steady flow tank, a first electric control valve, a variable frequency pump, a two-way compensator, a second electric control valve, a water tank body, an upper shaft sleeve, a lower shaft sleeve, a rotary shaft, a motor, a rotary ring, two rotary horizontal rods, two rotary vertical rods and floating blocks, wherein the upper part of the rotary shaft penetrates the upper shaft sleeve, the bottom of the rotary shaft is mounted on the lower shaft sleeve, at least one locating elongated slot is formed in the circumferential surface of the rotary shaft, and the locating elongated slot is parallel to the axis of the rotary shaft; a motor shaft is fixed with the rotary shaft; the rotary shaft is sleeved with the rotary ring, the rotary ring is provided with a bulge block matched with the locating elongated slot, and the rotary ring can rotate along with the rotary shaft and can move vertically along the rotary shaft; the two rotary horizontal rods are symmetrically fixed on two sides of the rotary ring, and bottom surface bristles are fixed on the rotary horizontal rods; the two rotary vertical rods are fixed with the two rotary horizontal rods respectively and fixedly equipped with side surface bristles; the floating blocks are fixed to the rotary horizontal rods. The integrated tank type two-way compensation non-negative-pressure water supply equipment has the beneficial effects of being reasonable in structure, convenient to clean and maintain and high in cleaning efficiency.

Description

technical field [0001] The invention relates to a water supply device which can provide domestic water to high-rise buildings. Background technique [0002] In the early high-rise buildings, the top-floor water tank was used for water supply, and the tap water pipes stored the water in the top-floor water tank. The disadvantages were that it was inconvenient to clean the water tank, and the water quality was difficult to guarantee. The existing water supply method was basically through frequency conversion. The control mode of the motor is used to supply power. In order to eliminate the negative pressure impact on the water pipe network, a small water tank is usually connected before the variable frequency motor. It is designed as a fully sealed structure. Therefore, it is necessary to regularly clean the water tank. The cleaning equipment in the prior art has a complicated structure and high cost. Contents of the invention [0003] Based on the above disadvantages, the p...
