Pipe network pressure-superposed matched high-level regulation and storage water supply device
Technical Field
The utility model relates to a water treatment field, in particular to no negative pressure water supply equipment.
Background
Aiming at a multi-building centralized water supply residential district with excessively centralized water consumption, large instant water consumption or high water supply requirement guarantee rate, a water supply scheme is needed, the lowest pressure water supply of a water supply main pipe is taken into consideration, and the gap of municipal water supply quantity in the peak period of water consumption is made up by means of storage regulation.
SUMMERY OF THE UTILITY MODEL
The purpose of the present invention is to solve at least one of the technical drawbacks.
Therefore, an object of the utility model is to provide a network of pipes is folded and is pressed high-order regulation and hold water supply installation of cooperation, include: the system comprises a municipal water supply network, a steady flow tank, a water supply pump set, a high-level water tank, a water tank self-flow water supply user pipe network, a pressure-superposed water supply user pipe network and a control cabinet;
the water supply pump set is formed by connecting more than two variable frequency water pumps and a bypass pipeline in parallel, a water inlet pressure sensor is arranged at the water inlet end of the pump set, and an air pressure tank and a water outlet pressure sensor are arranged at the water outlet end of the pump set;
the high-level water tank is sequentially provided with an electric valve and a ball cock along the direction of the water inlet pipeline;
the pressure-superposed water supply user pipe network is connected with the front end of the water inlet pipeline in parallel and is provided with a pressure reducing valve;
the municipal water supply pipe network, the steady flow tank and the water supply pump set are sequentially connected through pipelines;
the water supply pump group is connected with more than one high-level water tank and more than one parallel water inlet pipeline of the pressure-superposed water supply user pipe network;
the water outlet pipeline of the high-level water tank is connected with the self-flowing water supply user pipe network of the water tank;
the control cabinet is respectively connected with the variable frequency water pump, the water inlet pressure sensor, the water outlet pressure sensor and the electric valve through lines.
The utility model has the advantages and positive effects that: according to municipal water supply network flow, pressure all can't satisfy many building districts and concentrate water supply water demand, water supply system carries out the pipe network according to municipal water supply network at the minimum water supply pressure of the biggest water supply volume of water peak period and water supply main, to some building seats and stacks and press the water supply, all the other building seats adopt the water non-peak period water tank retaining of water, the water peak period water tank is from the form water supply, it stacks and supplies water to have realized taking into account regulation water supply and make full use of municipal pipe network pressure.
