Claims

[Scope of utility model registration request]

The interior of the valve box, which has an inlet on one side and an outlet on the other side, is connected to a communication chamber from above by a pair of horizontal partition walls fixed to the inner wall of the valve box at a predetermined interval in the vertical direction, and an inlet having the inlet. a chamber and an outflow chamber having the outflow port, and a hollow cylindrical valve body whose upper and lower ends are open is inserted into the three chambers so as to be slidable vertically through the partition wall,
The middle part of the peripheral wall of the valve body is formed as a flow rate control part in which a large number of small holes in a tapered shape with a large diameter on the outer circumferential side are bored, and the upper part on the communication chamber side from this flow rate control part is connected to the inflow chamber. Formed as a completely closed part that can be shut off, and a lower part on the outflow chamber side from the flow rate control part is formed as a fluid introduction part with a plurality of through holes, and when the flow rate control part is located in the inflow chamber, A pair of first sliding protrusions capable of slidingly contacting the inner periphery of the communication chamber are provided in an annular shape on the outer periphery of the valve body facing both the partition walls,
Further, when the fluid introduction part is located in the inflow chamber and the lower first sliding contact protrusion is located opposite to the upper partition wall,
A second sliding contact protrusion is provided in an annular shape on the outer periphery of the valve body facing the lower partition wall, and when the fluid introduction part is located in the inflow chamber, the tip thereof opens into the communication chamber facing the flow rate control part. A cleaning device for a flow rate control valve, further comprising: a discharge pipe having a rear end opened outside the valve box; and a stop valve provided on the discharge pipe.
