How to clean the S-pipe valve for pumping accessories!

Cleaning method for pumping accessories S pipe valve.

1, check the wear and tear between the alloy spectacle plate and cutting ring, which is the key to decide the success or failure of the direct hit water method of cleaning. If the wear of the spectacle plate and cutting ring is not serious, the spacing between the alloy cutting ring and spectacle plate is <0.1mm, and there is no groove scratch between them of more than 1mm, the direct water pumping method can be used.

2. After pumping the concrete and then pumping 0.15 to 0.25m+3 mortar with a water to ash ratio of 1:1.5 or 1:2, then fill the distribution valve with water, start pumping and pump the concrete to the pouring place until clear water flows out of the output end of the delivery pipe. If the pipe is short and the cleaning effect is good, the cleaning process ends here.

3、When the pipe is long or the cleaning effect is not so good, open the hopper discharge door, open the counter pump and flush the hopper and distribution valve clean. If pumping upwards and the height is >20m, use a wooden hammer to knock on the vertical part of the bottom bend, if the knocking sound is low, you need to dismantle the bend and pour out the large aggregate that may accumulate.

4、Close the discharge door and pump the water until it flows out from the output of the conveying pipe.

5、The advantage of the direct water method is that it is not necessary to remove the outlet pipe and add cleaning ball, saving time, pumping is easier to succeed, especially convenient for cleaning shorter pipes.

Its disadvantages.

① water consumption and pumping must be continuous, water is easily discharged in the pouring place.

②If there is a vertical upward pipeline, the bend must usually be removed; ③There are easy residues in the pipeline when the conveying line is long.

④Strict requirements for the sealing of the distribution valve.
