Embodiment

Like Fig. 1,2,3,4, shown in 5: 13 is the last liquid pipe that is connected with liquid pump.The 2 following liquid pipes that are connected with liquid bath for the top.

There is the threeway 4 of band side exit 23 in the outside below following liquid pipe 2; Form main cavity 22 between the threeway 4 times and water pipe 2 outsides; Concrete structure is between the upper end of threeway 4 and following liquid pipe 2, to be set with liquid overcoat 3 down; The upper end of following liquid overcoat 3 is sleeved on down on the liquid pipe 2, and the lower end of following liquid overcoat 3 is sleeved on the upper end of threeway 4.It is drain pan that the bottom of threeway 4 is fixedly connected with

adapter sleeve

6,8, and drain pan 8 is fixedly connected with the adapter sleeve screw thread, and clamping has following liquid pipe end shutoff film 5 in the upper end of drain pan 8.

Penetrated discharge pressure pipe 7 on the following liquid pipe end shutoff film 5, fastening suit between discharge pressure pipe 7 and the following liquid pipe end shutoff film 5.Liquid pipe 2 bottom nozzles were communicated with following liquid pipe 2 inner chambers under main cavity 22 passed through, and main cavity 22 is connected with the drain pan 8 inboard cavitys 24 of paying through discharge pressure pipe 7.Be provided with core bar 9 in the center pit of discharge pressure pipe 7, core bar 9 can move axially in discharge pressure pipe 7 and the bottom headstock drops on the bottom surface of drain pan 8.

Be communicated with the float valve of choosing 19 in the side of drain pan 8, float valve 19 joins with float 18.

Be provided with connecting pipe 10 between following liquid pipe 2 and the last liquid pipe 13, connecting pipe 10 is provided with second valve 11.

Last liquid pipe 13 bottoms and liquid pump connecting pipe 17 join, and between last liquid pipe 13 and liquid pump connecting pipe 17, are provided with non return part.Non return part comprises the last liquid overcoat 14 that is sleeved on liquid pipe 13 lower ends, and the upper end of liquid pump connecting pipe 17 is set with liquid and traps 16, and last liquid overcoat 14 and last liquid are trapped and is threaded between 16 and clamping has last liquid pipe shutoff film 15.The periphery of last liquid pipe shutoff film 15 is clamped in last liquid overcoat 14 and last liquid is trapped between 16, is processed with arc cutting line 20 on the last liquid pipe shutoff film 15, when the 20 inner perks of arc cutting line, on last liquid pipe shutoff film 15, forms mesopore 21.

Following liquid pipe 2 upper ends are provided with first valve 1 and are connected with strainer filter 25, are provided with the 3rd valve 12 in last liquid pipe 13 upper ends.Wherein strainer filter 25 tops are the liquid tail pipe 27 that is connected with liquid bath; The below side has the 4th valve 26; At the strainer filter 25 inner fluid passages of turning back that form, guaranteed that impurity has deposition to a certain degree and passes through 26 discharges of the 4th valve in the liquid in strainer filter 25.

The course of work is following: the upper end of going up liquid pipe 13 is connected with liquid bath, and liquid pump connecting pipe 17 joins with liquid pump, and it is inner that liquid tail pipe 27 inserts liquid baths, exports 23 and is connected with the liquid filter pocket through pipeline, and float 18 is positioned at the liquid filter pocket.Earlier with closing the 3rd valve 12 after the liquid pump energising, open second valve 11 and first valve 1 when using first, downwards fluid injection in the liquid pipe 2; Close second valve 11 when treating the Guan Zhongwu air, open the 3rd valve 12, total system is started working; Promptly from last liquid pipe 13 pump liquid in liquid bath, liquid pipe shutoff film 15 middle parts are upturned on this moment, and the liquid in the liquid bath is from liquid pipe 2, outlet 23 are back in the liquid filter pocket down; Part liquid gets into from discharge pressure pipe 7 and pays in the cavity 24; Get in the liquid filter pocket through float valve 19, this moment, float 18 was in position, the end again, and float valve 19 is in open mode.The stall phenomenon appears like liquid pump, outside pump liquid in the liquid filter pocket no longer, but down liquid pipe 2 also at withdrawing fluid; Liquid level in the liquid filter pocket is risen, float 18 with on move, close float valve 19; Make and pay the increase of cavity 24 internal pressures; The 5 stressed upwards distortion of following liquid pipe end shutoff film, shutoff simultaneously the bottom nozzle of time liquid pipe 2, liquid is no longer flowed out in liquid bath; Go up simultaneously the liquid pipe shutoff film 15 middle part perks port of liquid pump connecting pipe 17 that partly fallen shutoff, reach the purpose of automatic control.It is more suitable that native system is applied to view and admire the water filtration of fish jar.Core bar 9 moves in discharge pressure pipe 8 through following moving up and down of liquid pipe end shutoff film 5, makes core bar 9 clear up the foreign material that stop up in the discharge pressure pipes 8 automatically, plays the purpose of automatic cleaning.
