1) Automatic judgment of channel blockage state through pressure change of inlet side and outlet side of fluid channel
As shown in fig. 1, when the valve cartridge 1 is in the normal fluid delivery position, fluid passes through the fluid inlet channel 2, the channel at the middle part of the valve cartridge 1, the filter screen 10 and then flows out to the fluid outlet channel 6. The inlet end valve core control branch 3 of the fluid inlet channel 2 flows through the valve core inlet pressure pushing cavity 5 to generate a leftward thrust on the right end of the valve core 1, and the outlet end valve core control branch 8 of the fluid outlet channel 6 flows into the left end of the valve core to generate a rightward thrust on the left end of the valve core 1.
The valve core 1 can automatically diagnose the blockage state of the outlet by comparing the thrust of the outlet fluid and the thrust of the inlet fluid at the left end and the right end.
2) Method for automatically controlling working position and flushing position by pushing valve core 1 through inlet and outlet fluid
As shown in figure 1, the section of the fluid inlet channel 2 leading to the thrust cavity at the right end of the valve core 1 is small, the section of the outlet 6 leading to the thrust cavity at the left end of the valve core 1 is large, and the automatic valve core position automatic switching judgment condition of normal conveying and blockage flushing is set through the design of the difference of the section sizes of the thrust cavities at the left end and the right end of the valve core 1.
Under the normal fluid conveying state, the left side of the valve core 1 is subjected to outlet fluid thrust which is larger than the right side of the valve core 1 is subjected to inlet fluid thrust, and the valve core 1 is in a right end limit position. The inlet flushing branch 4 and the outlet flushing branch 7 are separated by the valve core 1, and the flushing channel is closed.
As shown in fig. 2, when the foreign matter accumulated on the filter screen 10 affects the use requirement and reaches the designed set flushing condition, the automatic flushing starts, the left side of the valve core 1 is pushed by outlet fluid smaller than the right side, and the valve core 1 is pushed to the left end limit position. The channel of the fluid which directly flows into the outlet 6 through the inlet 2 is cut off by the valve core 1, the inlet flushing branch 4, the outlet flushing branch 7 and the flushing discharge channel 9 of the flushing channel are automatically opened for flushing and deslagging, a little fluid flows to the outlet 6 and the outlet valve core control branch 8 through the filter screen 10, and the left end and the right end of the valve core 1 are still under the action of the pressure of the inlet fluid and the outlet fluid to detect the fluid conveying state in real time.
When the accumulated foreign matter of the filter screen is cleaned up to reach the design set condition, the left end thrust of the valve core 1 is increased, the valve core 1 is pushed to move rightwards to the right limit position, the state shown in the figure 1 is recovered, and the normal conveying work is started.
The normal working position and the flushing position of the valve core 1 are switched in the whole working process, and the valve core is self-diagnosed, self-switched and self-cleaned, and cleaned and dredged in time in cycles, thereby achieving the function which cannot be realized by the conventional method.
