Preferably, the valve core is a cylindrical box body, and the side surface of the valve core is tightly attached to the inner wall of the rotary cloth valve body.

Preferably, the Y-shaped channel is an inverted Y-shaped channel, and the section of any position of the Y-shaped channel is a circular ring.

The invention has the following beneficial effects:

1. according to the coal mine paste filling rotary distribution valve, a traditional transmission structure of a gear and a screw rod is changed into an all-gear transmission structure, so that on one hand, the transmission mode can ensure that the gear is less in wear, the screw rod is not required to be replaced frequently, and the working efficiency is influenced; on the other hand, the self-tightening characteristic of the gear can ensure that the valve core is more compact after being closed, and the leakage of the paste cannot be caused.

2. This colliery lotion fills and revolves cloth valve, through setting up the inside case that has "Y" style of calligraphy passageway, the inside of this kind of case is hollow, it is lighter to compare traditional solid case quality, consequently can guarantee the saving of energy consumption, and compare the case of current hollow structure, be provided with confined cavity between case and inside "Y" style of calligraphy passageway, just so can guarantee that the lotion can not flow into the inside of case and pile up, only flow in the inside of "Y" style of calligraphy passageway, guarantee the inside cleanness of case, the life of case is improved.
