Embodiment Construction
[0013] figure 1 The water supply system shown is a system for supplying water to buildings with a floor height of 13 floors. Since the annual maximum pressure water supply height of the municipal pipe network is 8 floors, and the annual minimum pressure water supply height of the municipal pipe network is 5 floors, so this example will 1~ The 5th floor is defined as the direct water supply section, the 6th to 8th floors are defined as the dynamic water supply section, and the 9th to 13th floors are defined as the superimposed water supply section, and the head of the superimposed water supply circuit is calculated based on this.
[0014] see figure 1 , the whole system is composed of the numerical control device KZX and the water supply circuit, wherein the water supply circuit is composed of the shut-off valve ZF1 and the backflow preventer NZ in series before the parallel circuit formed by the superimposed water supply circuit and the direct water supply circuit. The superi...

The invention discloses a dynamic pipe network pressure-superposed water supply system, which is characterized in that: a numerical device detects the water supply pressure of a municipal pipe network; floors above a water supply height under annual maximum pressure of the municipal pipe network are defined as a pressure-superposed water supply section; floors below a water supply height under annual minimum pressure of the municipal pipe network are defined as a direct water supply section; floors between the pressure-superposed water supply section and the direct water supply section are defined as a dynamic water supply section; an outlet of a pressure-superposed water supply loop is connected with a vertical pipe of a water supply pipeline between the pressure-superposed water supply section and the dynamic water supply section; vertical pipes of interfloor water supply pipelines of the dynamic water supply section and both ends of the dynamic water supply section are respectively and serially connected with an electromagnetic valve; an inlet of a direct water supply loop is serially connected with a teletransmission pressure gauge; the numerical control device determines to close a corresponding electromagnetic valve according to the water supply pressure of the municipal pipe network, performs pressure-superposed water supply for floors above the closed electromagnetic valve, and performs direct water supply for floors below the closed electromagnetic valve.
Description
technical field [0001] The invention relates to a water supply system, in particular to a pipe network superimposed water supply system. Background technique [0002] Due to the obvious defects of the traditional secondary water supply technology that the water quality is susceptible to secondary pollution and the residual pressure of the municipal pipe network cannot be utilized, researchers have gradually shifted their research focus to a pipe network overlapping water supply technology solution. The scheme is mainly to set up direct water supply circuits and superimposed water supply circuits respectively to implement vertical water supply for buildings. The highest floor and the lower floors of the municipal pipe network that can directly supply water with the lowest pressure all the year round are supplied by the direct water supply circuit. The municipal pipe network has the highest perennial Floors above the highest floor where pressure can be directly supplied with w...
