Description
Technical field
The utility model relates to the field of tap water supply equipment.
Background technology
At present, the water supply installation of high-rise building comprises the water tank that is communicated with water supply pipe, water tank supplies water for the user by water pump, under normal circumstances, water pump can satisfy user's demand, but under the condition of tap water supply quantity not sufficient, the water level of water tank will be pumped down to low water stage, present vacuum (negative pressure) state in the water tank, influence normal water supply, not water outlet of service pipe.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of non-negative pressure water-supply installation that can solve negative pressure problem in the water tank to be provided.
The purpose of this utility model is achieved in that non-negative pressure water-supply installation, comprise water inlet pipe, one end of water inlet pipe connects the water inlet end of water tank, the water side of water tank connects at least one road water supply installation, every road water supply installation comprises that respectively first connects water pipe, on the first connection water pipe first valve is set, first end that connects water pipe connects described water tank, the other end connects the input of water pump, the output of water pump connects second and connects water pipe, on the second connection water pipe one way valve and second valve are set, second other end that connects water pipe connects service pipe, and pressure sensor is set on the service pipe, and described water pump is connected with same variable frequency control cabinet respectively with pressure sensor, the top of described water tank is provided with vacuum suppresser, and the bottom of water tank is provided with level sensor.
The utility model is equipped with vacuum suppresser by the top at water tank, and when negative pressure appearred in water tank, vacuum suppresser moved immediately, and negative pressure is eliminated, and in the water tank bottom level sensor is housed, when the water tank lack of water, and protection automatically.Output at equipment is equipped with pressure sensor with the service pipe place of connection, and this pressure signal is delivered in the variable frequency control cabinet, and the rotating speed through control of pump after the computing of single-chip microcomputer in the variable frequency control cabinet makes the whole system output pressure stable.Adopt the non-negative pressure water-supply installation of this structure, simple in structure, working stability, noise are little, suit to use in various pressurization water supply occasions, are particularly suitable for building that quality of water supply has relatively high expectations and supply water and use.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, non-negative pressure water-supply installation comprises water inlet pipe 1, and an end of water inlet pipe 1 connects the water inlet end of water tank 3, and the top of water tank 3 is provided with vacuum suppresser 4, and the bottom of water tank 3 is provided with level sensor 2.The water side of water tank 3 connects at least one road water supply installation, every road water supply installation comprises that respectively first connects water pipe 5, on the first connection water pipe 5 first valve 6 is set, first end that connects water pipe 5 connects water tank 3, the other end connects the input of water pump 7, the output of water pump 7 connects second and connects water pipe 12, on the second connection water pipe 12 one way valve 10 and second valve 11 are set, second other end that connects water pipe 12 connects service pipe 13, pressure sensor 9 is set on the service pipe 13, and water pump 7 is connected with same variable frequency control cabinet 8 respectively with pressure sensor 9.
