Through setting up the high-pressure rubber tube, make things convenient for the setting and the connection of the pipeline of business turn over liquid, inlet, liquid outlet all adopt DN32 standard joint, further make things convenient for being connected of opening and high-pressure rubber tube.
The pipeline of the liquid inlet is provided with a pressure gauge.
Through setting up the manometer, be convenient for monitor the pressure of the confession liquid of inlet department.
The pipeline connection between the liquid inlet and the liquid outlet is through a quick connector.
Through setting up quick-operation joint, make things convenient for the connection of part and pipeline.
The backflushing sewage draining outlet is communicated with the liquid drainage buffer tank.
Through setting up the flowing back baffle-box, conveniently wash the discharge of waste liquid.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1-3, a high pressure emulsion backwash filter station consists of a filter unit, an operating valve 4 and a connecting pipeline; the filtering station is provided with 2 filtering units, each filtering unit is provided with a filter and a two-position two-way valve 2, the filters are provided with filtering valves, the liquid inlet side of each filter is communicated with a liquid inlet 7 through the two-position two-way valve 2, the liquid outlet side of each filter is communicated with a hydraulic device of a hydraulic support through a liquid outlet 8, the liquid inlet side of each filter is communicated with a backflushing sewage outlet 6 through a hydraulic control one-way valve 3, the control ports of the two-position two-way valves 2 are communicated with the liquid inlet 7 through control valves 4, and the control valves 4 control the two-position two-way; the bypass valve 5 is connected in parallel with the filter 2 between the liquid outlet 88 and the two-position two-way valve 2.
