Abstract
The utility model discloses a frost cracking prevention system for a water pump. Liquid in the water pump freezes due to cold weather in winter, and the volume of the frozen liquid expands to cause frost cracking of the water pump. The frost cracking prevention system is characterized in that the water inlet side of the water pump is provided with a first normally-closed solenoid valve, and the water outlet side of the water pump is provided with a fourth normally-closed solenoid valve; a water inlet side three-way pipe is arranged between the first normally-closed solenoid valve positioned on the water inlet side and the water pump, a middle outlet of the water inlet side three-way pipe is upward and connected with a first pipeline, and a second normally-closed solenoid valve is arranged at the tail end of the first pipeline; a water outlet side three-way pipe is arranged between the fourth normally-closed solenoid valve positioned on the water outlet side and the water pump, a middle outlet of the water outlet side three-way pipe is downward and connected with a second pipeline, and a third normally-closed solenoid valve is arranged at the tail end of the second pipeline, and all the normally-closed solenoid valves and the water pump are connected with a single-chip microcomputer control system respectively. After the water pump is not used, the frost cracking prevention system for the water pump can automatically drain the liquid in the water pump to achieve the purpose of preventing the water pump from frost cracking.
Description
Technical field
The utility model relates to the control system of water pump, specifically a kind of water pump frost-cracking-preventing control system.
Background technique
Winter, the liquid in water pump can freeze due to cold weather, and volumetric expansion after liquid freezes, cause the water pump bursting by freezing.At present the frost-cracking-preventing method of water pump mainly contains: 1. water pump is arranged on indoor, but under actual conditions mostly inconvenience be arranged on indoor; 2. the defroster that can generate heat is placed on the outside of water pump body, but defroster self will switch on power for a long time, consumes electric energy; 3. at the two ends of water pump, drain valve is installed, but is all needed manually to go to open at every turn.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defect that above-mentioned prior art exists, a kind of water pump frost-cracking-preventing control system is provided, after it can finish in each use of water pump, automatically emptying the water in water pump, thus reach the frost-cracking-preventing purpose of water pump.
For this reason, the technical solution adopted in the utility model is as follows: a kind of water pump frost-cracking-preventing control system, comprise water pump, and it is characterized in that: the influent side of described water pump is provided with the first normally closed solenoid valve, and the water outlet side of water pump is provided with the 4th normally closed solenoid valve; Be provided with the influent side three-way pipe between the first normally closed solenoid valve of influent side and water pump, the central exit of this influent side three-way pipe and connect the first pipeline, is provided with the second normally closed solenoid valve at the end of the first pipeline up; Be provided with the water outlet side three-way pipe between the 4th normally closed solenoid valve of water outlet side and water pump, the central exit of this water outlet side three-way pipe down and connect the second pipeline, end at the second pipeline is provided with the 3rd normally closed solenoid valve, and all normally closed solenoid valves are connected with water pump with a single-chip computer control system and are connected.
Further, the distance of described the first, the 4th dried up pump of normally closed solenoid valve is preferably 30-50 centimetre, and convenient the installation after water pump is stopped using, reduced the water accumulating volume that pump two side pipe domestic demands will be discharged.
Further, the length of described first, second pipeline is preferably 10-20 centimetre, the convenient installation, and need the water accumulating volume of discharging in the minimizing pipe.
Further, the pipeline of described water feeding of water pump side, than the high 3-5 ° of the pipeline of water outlet side,, due to tilting action, after water pump is stopped using, can facilitate the ponding in pump to discharge.
The utility model after each use of water pump finishes, can, automatically the emptying rate of liquid in water pump, reach the frost-cracking-preventing purpose of water pump; Simple, convenient.
