A above water valve, is provided with water pump C and more than one water valve between the connecting pipe and outlet pipe；The major cycle
System is made of sequentially connected water inlet pipe, closed cooling tower and outlet pipe, and major cycle water valve a is provided on the water inlet pipe,
Major cycle water valve b is provided on the outlet pipe；The water inlet pipe of the partial circulating is a part of the water inlet pipe of major cycle, described
The outlet pipe of partial circulating is a part of the outlet pipe of major cycle.
Pipeline heat cycles are provided on the water inlet pipe of the partial circulating, the pipeline heat cycles are by sequentially connected water
Valve, pipeline heater and water valve composition.
Compared with prior art, the utility model has the following beneficial effects:
The closed cooling tower anti-freeze type circulation of the utility model works as cold by major circulatory system and lesser circulation
Winter come interim, when cooling tower needs short-term close, close major circulatory system, lesser circulation only run, when water in pipeline
It, can be with in-service pipeline heat cycles when temperature is too low；When needing to run cooling tower, lesser circulation is closed, runs major cycle
System；Not only it had been avoided that the problem of water freezing causes coil frost broken in cold winter coil pipe, but also has been avoided that cooling tower is closed in short term
Drain water in coil pipe and caused by problem of resource waste.
Detailed description of the invention:

Specific embodiment:
Specific embodiment of the present utility model is described in detail below, it is to be understood that the protection of the utility model
Range is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, closed cooling tower anti-freeze type circulation, the circulation is by lesser circulation 1 and master
The circulatory system 2 forms；The lesser circulation 1 is by sequentially connected water inlet pipe 11, closed cooling tower 12, outlet pipe 13 and connects
Adapter tube road 14 forms, and the connecting pipe 14 connects water inlet pipe 11 and outlet pipe 13, is provided with one in the connecting pipe 14
Above water valve 15 is provided with water pump C16 and more than one water valve 15 between the connecting pipe 14 and outlet pipe 13；Institute
It states major circulatory system 2 to be made of sequentially connected water inlet pipe 21, closed cooling tower 12 and outlet pipe 23, be set on the water inlet pipe 21
It is equipped with major cycle water valve a24, major cycle water valve b25 is provided on the outlet pipe 23；The water inlet pipe 11 of the partial circulating is main
A part of the water inlet pipe 21 of circulation, the outlet pipe 13 of the partial circulating are a part of the outlet pipe 23 of major cycle.
Pipeline heat cycles 17 are provided on the water inlet pipe 11 of the partial circulating, the pipeline heat cycles 17 are by successively connecting
Water valve 15, pipeline heater 18 and the water valve 15 connect forms.
When implementation, come temporarily when cold winter, equipment needs to close in short term, at this time by the major cycle of major circulatory system 2
Water valve a24 and major cycle water valve b25 is closed, and opens all water valves 15 of lesser circulation 1, and opens water pump C16, small at this time to follow
Loop system 1 is in operating status, and when water temperature is too low in coil pipe, opening conduits heat cycles 18 follow the water in pipeline
