The invention relates to the technical field of descaling valves, and discloses a descaling valve for descaling, which comprises a descaling valve body, a water outlet and a transparent tank body, the water outlet is arranged at the top of the descaling valve body, the transparent tank body is arranged at the bottom of the descaling valve body, and a liquid speed adjusting
assembly for controlling the flowing speed of a
water source is arranged on the outer side of the descaling valve body. An anti-blocking
assembly used for preventing the top of the transparent tank body from being blocked is arranged in the descaling valve body, through the arrangement of a power
assembly and a liquid speed adjusting device, the flow speed of a
water source entering the descaling valve body is limited through a liquid blocking block, finally the purpose of reducing the flow speed of liquid is achieved,
intelligent control over the flow speed of
water flow is achieved, and when the flow speed of the
water source is too high, the anti-blocking assembly is started. The
system can make a response in time to reduce the flow speed, the descaling effect and
safe operation of equipment are ensured, secondly, the situation that when a traditional descaling valve faces
water flow with the too high flow speed, the pressure is too large due to the
water hammer effect, the valve and a pipeline are damaged is avoided, and damage of the
water hammer effect and the like to the equipment is reduced.
