Abstract
The utility model discloses a cooling water sprinkler with a recession device. The cooling water sprinkler solves the problem that a pipe used by a cooling water sprinkler in the prior art is frozen and blocked easily in the machining process. The cooling water sprinkler comprises a pushing water pump, a water inlet pipe, a water return pipe and a nozzle. The pushing water pump is connected into the water inlet pipe. A back pumping water pump is connected into the water return pipe. A water inlet of the water inlet pipe and a water outlet of the water return pipe are connected into two outlets of a first electromagnetic three-way valve respectively. A water outlet of the water inlet pipe and a water inlet of the water return pipe are connected into two outlets of a second electromagnetic three-way valve respectively. As the cooling water sprinkler is different from an existing common cooling water sprinkler, the back pumping water pump can be adopted for carrying out back flowing and then pushing so that the problem of blocking of a pipeline can be solved. After the cooling water sprinkler is used in winter, the back pumping water pump can be adopted for pumping water in the pipeline into a cooling water tank to empty the pipeline, and therefore icing can be prevented; the operation trouble of workers can be reduced, and the production efficiency can be improved.
Description
Technical field
This utility model relates to a kind of sprinkling device for cooling water, particularly relates to a kind of sprinkling device for cooling water with water recession device.
Background technology
At present, existing sprinkling device for cooling water adopts flow by gravity formula and the electronic formula that pumps into more, because the water pipe of cooling water is generally partially thin, in the workshop in winter, more easily freezes.Due to the spray line of cooling water end, its diameter is significantly less than the water supply line of leading portion, and sometimes the foreign matter in cooling water, can stop up the thinner portion of diameter.Cause stopping of manufacturing process, increased workman's troublesome poeration, the waste unnecessary production time of enterprise, cause production efficiency low.
Utility model content
The utility model has overcome in prior art, the sprinkling device for cooling water using in mechanical processing process, and the problem that pipe easily freezes and stops up, provides a kind of sprinkling device for cooling water with water recession device simple in structure, easy to use.
Technical solution of the present utility model is, provide a kind of sprinkling device for cooling water with water recession device with following structure: contain and push water pump, water inlet pipe, return pipe and nozzle, in described propelling movement water pump access water inlet pipe, in the access of falling suction pump return pipe, the water inlet of water inlet pipe and the delivery port of return pipe access respectively two exits of the first three-way solenoid valve, and the delivery port of water inlet pipe and the water inlet of return pipe access respectively two exits of the second three-way solenoid valve.Water inlet pipe and return pipe are sinuous coil or rubber hose.Propelling movement water pump and the suction pump that falls are centrifugal water pump.
Compared with prior art, the utility model has the following advantages with the sprinkling device for cooling water of water recession device: different from existing common sprinkling device for cooling water, line clogging can adopt down suction pump to reflux and push and solve again.Can adopt down suction pump by water suction chilled water tank pipeline in after using winter, and pipeline is put to sky, can prevent the phenomenon of freezing.The troublesome poeration that has reduced workman, has improved production efficiency.
Accompanying drawing explanation
Fig. 1 is that the utility model is with the structural representation of the sprinkling device for cooling water of water recession device.
The specific embodiment
In accompanying drawing explanation, label 1 is chilled water tank, the 2nd, fall suction pump, and 3 is first three-way solenoid valves, the 4th, push water pump, 5 is second three-way solenoid valves, the 6th, nozzle.
Below in conjunction with the drawings and specific embodiments, to the utility model, the sprinkling device for cooling water with water recession device is described further: as shown in the figure, in the present embodiment, contain and push water pump 4, water inlet pipe, return pipe and nozzle 6, in described propelling movement water pump 4 access water inlet pipes, fall in suction pump 2 access return pipes, the water inlet of water inlet pipe and the delivery port of return pipe access respectively two exits of the first three-way solenoid valve 3, and the delivery port of water inlet pipe and the water inlet of return pipe access respectively two exits of the second three-way solenoid valve 5.Water inlet pipe and return pipe are sinuous coil or rubber hose.Propelling movement water pump 4 and the suction pump 2 that falls are centrifugal water pump.Workman in use, can be controlled the ac conducting of the first three-way solenoid valve 3 and the second three-way solenoid valve 5 simultaneously and be pushed water pump 4 work by gauge tap, cooling water can be sent into cooling position by water inlet pipe.By the time workman After Hours, in order to prevent the cooling water pipe that diameter is less, for a long time need not, the situation of icing effect second day work, can control the ab conducting of the first three-way solenoid valve 3 and the second three-way solenoid valve 5 and fall suction pump 2 work by switch, in a cooling fluid pumpback chilled water tank 1 residual in pipeline, put vacant duct, avoid icing.If there is foreign matters from being blocked in pipeline, cause flow of cooling water not smooth, also can repeat to prevent icing control operation, foreign matter is taken out and pushed, repeat several times, can get rid of.
Claims (3)
1. a water-cooling-sprayer water recession device, contain and push water pump, water inlet pipe, return pipe and nozzle, it is characterized in that: in described propelling movement water pump access water inlet pipe, in the access of falling suction pump return pipe, the water inlet of water inlet pipe and the delivery port of return pipe access respectively two exits of the first three-way solenoid valve, and the delivery port of water inlet pipe and the water inlet of return pipe access respectively two exits of the second three-way solenoid valve.
2. water-cooling-sprayer water recession device according to claim 1, is characterized in that: described water inlet pipe and return pipe are sinuous coil or rubber hose.
