Lower part be designed with inlet 11, the outlet of working line 3 of the inlet 11 with needing to clean is connected, the cleaning valve casing
1 top is machined with the liquid outlet 12 and Butterworth Hatch 13 connected with the valve chamber, and the Butterworth Hatch 13 is connected with return line 4,
The return line 4 is connected by distributor 5 with the working line 3；21 He of feed pathway is machined with the cleaning spool 2
Flushing channel 22, when right position that the cleaning spool 2 is moved to, are set as operating position and cleaning positions, when described clear
When washing spool 2 and being located at operating position, the feed pathway 21 connects the inlet 11 and liquid outlet 12, when the purge valve 2
During positioned at cleaning positions, the flushing channel 22 connects the inlet 11 and Butterworth Hatch 13, is also processed on the cleaning valve casing 1
There is cleaning agent mouth 14, be equipped with the cleaning valve casing 1 and add agent module 6, when the cleaning spool 2 is located at operating position, institute
State and add agent module 6 and connected by cleaning agent mouth 14 with flushing channel 22, assembled between the Butterworth Hatch 13 and the return line 4
There is compression module 7.
Fluid path auxiliary flushing valve device is assemblied in the 3 outlet end portion of working line for needing fixed time cleaning, the work
Pipeline 3 also includes the liquid storage structure with cavity body structure, and the working line 3 can be defeated for completing mixing of the equipment to liquid
The function such as send.When working line 3 works normally, the cleaning spool 2 is located at operating position, the feed pathway 21 and feed liquor
Mouth 11, liquid outlet 12 form passage so that the liquid for flowing through the working line 3 smoothly flows out.At the same time in the instrumentation tubes
When road 3 works normally, it can add agent module 6 by described into flushing channel 22 and add cleaning agent.
When working line 3 needs cleaning, slide the cleaning spool 2 and arrive cleaning positions, at this time the flushing channel 22
Connect the inlet 11 and Butterworth Hatch 13 so that working line 3 accesses return line 4, so clean water can be passed through
Working line 3 enters return line 4 so that the working line 3 is filled with clean water with return line 4, then by the work
Make the water inlet cut-out of pipeline 3 so that working line 3 forms circulating path with return line 4.In the effect of the compression module 7
Line, the working line 3 are circulated with the clean water in return line 4, due to adding before having in the flushing channel 22
The cleaning agent added so that the cleaning solution that clean water and cleaning agent are mixed into can flow repeatedly in circulation line, so as to institute
State working line to be washed away repeatedly, complete cleaning process.Return line 4 is opened after the work is completed, and waste liquid is flowed out, clearly
Clean water from working line 3 flow through by working line 3 mix detergent cleaning solution washes away, working line 3 clean up with
Afterwards, slide the cleaning spool 2 and arrive operating position so that working line 3 works normally.The apparatus structure is simple, easy to use,
Working line 3 can be washed away repeatedly, cleaning performance is more preferable, while is carrying out clean cycle by the flushing channel 22
When cleaning agent is put into reflux cycle, it is not necessary to design extra structure, structure is more compact.
In the apparatus, when normal work needs to use clean water in working line 3, the working line 3 can be straight
Connected distributor 5 and add clean water, then clean water passes through purge valve after being mixed with the other liquid being passed through in working line 3
The inlet 11 of shell 1 and the feed pathway 21 of cleaning spool 2 export.When needing cleaning, by other liquid for mixing
Feed pathway is closed, and only retains the entrance of clean water so that clean water can be by the mixing liquid in working line 3 from inlet
11 and feed pathway 21 export, when mixed liquor arranges light soon in working line 3, will cleaning spool 2 be pushed to cleaning positions so that
Clean water enters return line 4 by flushing channel 22 in working line 3, when clean water is full of return line 4, adjusts distribution
Device 5 so that working line 3 forms circulation line with return line 4, then promotes current to flow by compression module 7.
And when in working line normal work clean water need not be passed through, it can be rushed by the liquid feed valve 51 with being used for
The clear water pipeline washed is connected.So when being cleaned, first pass through the liquid feed valve 51 and connect working line 3 and clear water pipeline
It is logical, clean water is poured into working line 3, is repeated the above process.
In specific design, as depicted in figs. 1 and 2, the distributor 5 includes three-way pipe, and the first of the three-way pipe
Port is connected with the input end of working line 3, and the second port of the three-way pipe is connected by liquid feed valve 51 with inlet pipe, institute
