the utility model provides a cold quick-witted water route filter automatic switching control equipment of liquid which characterized in that: the liquid inlet section of the main pipeline is connected with one end of the two filtering branches by taking one port of the electric three-way valve as a common end, the other two ports of the electric three-way valve are respectively connected with one end of the two filtering branches, and the other ends of the two filtering branches are connected to the liquid outlet section of the main pipeline.
The automatic switching device for the waterway filter of the liquid cooling machine is characterized in that: each filtering branch comprises a filter, and the inlet and the outlet of the filter are respectively connected with the corresponding port of the electric three-way valve and the liquid outlet section of the main pipeline through pipelines.
The automatic switching device for the waterway filter of the liquid cooling machine is characterized in that: each filtering branch further comprises a waterway ball valve, and the waterway ball valve is communicated with the filter in the corresponding branch in series through a pipeline.
The automatic switching device for the waterway filter of the liquid cooling machine is characterized in that: in each filtering branch, a pressure difference switch is connected between the inlet and the outlet of the filter, so that the pressure difference switch is communicated with the filter in parallel.
The automatic switching device for the waterway filter of the liquid cooling machine is characterized in that: the signal input end of the controller is connected with the pressure difference switch, the signal output end of the controller is in control connection with the electric three-way valve, and the controller controls the switching path of the electric three-way valve based on the signal of the pressure difference switch.
The invention is provided with two parallel filtering branches, one is used and the other is standby, the redundancy of the liquid cooling unit is improved, the reliability is further improved, the filter in each filtering branch is connected with the rear end in series and is provided with the waterway ball valve, when the filter element of one filtering branch needs to be cleaned, the waterway ball valve which is correspondingly connected is closed, the leakage of cooling liquid can be avoided, the online cleaning is realized, and the maintainability and the supportability of the liquid cooling unit are improved.
The filters of each filtering branch are respectively connected with a differential pressure switch in parallel, the differential pressure switch is used for detecting the pressure difference between the inlet and the outlet of the filter, when the filter used on line is dirty and blocked, the differential pressure switch outputs a signal to the controller, and the controller controls the electric three-way valve to be switched to the other filtering branch, so that automatic detection and seamless automatic switching are realized.
Compared with the prior art, the invention has the advantages that:
1) the double filters are arranged and connected in parallel, and one filter is used and one standby in function.
2) A pressure difference switch for detecting the pressure difference between the inlet and the outlet of each filter is arranged and used for judging whether the filter is dirty or not and sending out a fault signal.
3) An electric three-way valve is arranged for automatically switching two parallel filtering branches, so that the switching of the filter is realized.
4) The waterway ball valve is arranged, so that the corresponding branch water flow can be cut off when the filth blockage filter is removed.

FIG. 1 is a schematic diagram of the present invention.
Detailed Description
The invention is further illustrated with reference to the following figures and examples.
As shown in figure 1, the invention is composed of a 1# filter 1, a 2# filter 2, a 1# differential pressure switch 3, a 2# differential pressure switch 4, an electric three-way valve 5, a 1# waterway ball valve 6 and a 2# waterway ball valve 7 which are connected through pipelines. One end of the No. 1 filter 1 is connected with one end of a No. 1 waterway ball valve 6 through a pipeline, and the other end of the No. 1 filter 1 is connected with an A end 5.2 of an electric three-way valve 5 through a pipeline, so that a No. 1 filtering branch is formed; one end of the No. 2 filter 2 is connected with one end of a No. 2 waterway ball valve 7 through a pipeline, and the other end of the No. 2 filter 2 is connected with a B end 5.3 of an electric three-way valve 5, so that a No. 2 filtering branch is formed; the No. 1 filtering branch and the No. 2 filtering branch structurally form a parallel double branch, and a common C end 5.1 of the electric three-way valve 5 is directly connected with a water inlet section of the main pipeline 8; the other ends of the No. 1 waterway ball valve 6 and the No. 2 waterway ball valve 7 are connected to the water outlet section of the main pipeline in a sharing mode. A1 # differential pressure switch 3 is connected between two ends of the 1# filter 1, and a 2# differential pressure switch 4 is connected between two ends of the 2# filter 2. The automatic switching device can effectively operate under the control of the external controller.
In a default state, the controller sets the common end C end 5.1 and the A end 5.2 of the electric three-way valve 5 in an open state, sets the common end C end 5.1 and the B end 5.3 of the electric three-way valve 5 in a closed state, and at the moment, the 1# filtering branch and the 1# filter 1 are in a current value, and the 2# filtering branch and the 2# filter 2 are in a standby state. If the 1# filtering branch circuit sends a fault signal due to filth blockage of the filter after a certain time, the external controller receives the signal and then reverses the electric three-way valve 5, after the signal is reversed, the C end 5.1 and the B end 5.3 of the common end of the electric three-way valve 5 are in an open state, the C end 5.3 and the B end 5.2 of the common end of the electric three-way valve 5 are in a closed state, and at the moment, the 2# filtering branch circuit and the 2# filter 2 have current values.
