Abstract
The utility model relates to a cleaning device for a tiny drag slow shut check valve. The cleaning device comprises a valve body (1), a valve clack (2), a rotating shaft (3), a sealing surface (4) and a water pump outlet (5), and is characterized in that a hole (9), with a blow-off valve (6) and a blow-off pipe (7) arranged thereon, is formed on the valve body (1). On the cleaning device provided by the utility model, the blow-off valve and the blow-off pipe are additionally arranged, so that impurities are prevented from being accumulated in a valve cavity, and pressure water from the pipe is used for cleaning and blowing off to the sealing surface.
Description
Technical field
The utility model belongs to the hot-rolled strip steel equipment technical field, is a kind of novel Tiny Drag Slow Shut Check Valves washing unit specifically.
Background technique
Hot-rolled strip production line has number cover water treatment system, tens of of raw water service pumps, the most of Tiny Drag Slow Shut Check Valves of installing of exit of pump.The hot rolling line water treatment system is carried out closed-circuit, and oil-containing is many in the water quality, and it is many to contain the iron scale powder; Circulating water flow is when safety check, and impurity is deposited on the sealing surface in the water, causes closure of check ring not tight; Aqueous reflux makes and the motor reversing has damaged pump and pipeline during termination of pumping; Gas also is brought in the water pump during aqueous reflux besides, and startup need be carried out exhaust to water pump and could start after 3 to 5 minutes once more, jumps electricity if meet, and has increased the crash time, has influenced rolling rhythm.After valve closing is not tight; Miantainers open valve cleaning impurity or change valve; Valve is the above big valve of DN200 mostly, needs with operations such as artificial sled, driving handlings, and there is great potential safety hazard in worker's operation; Waste time and energy and run counter to fast pace, high efficiency, low cost, the production aim that ensures safety.
Summary of the invention
The purpose of the utility model provides a kind of Tiny Drag Slow Shut Check Valves washing unit of Rapid Cleaning check valve seal face, can overcome the shortcoming of above-mentioned valve accumulated impurity.The utility model solves the scheme that its technical problem adopted: this Tiny Drag Slow Shut Check Valves washing unit includes valve body, flap, rotating shaft, sealing surface and exit of pump, and perforate increases a blowdown valve and blowoff line on valve body.Drain pipe length is no more than 15 meters, in order to avoid produce back pressure, drain pipe do not have the slope of rising or and the elbow of process too much.Miantainers' blowdown every day once, method is operating Tiny Drag Slow Shut Check Valves to be opened the blowdown valve that increases discharge water, and accomplishes the cleaning blowdown of valve.
The utility model adds and cleans blowdown valve and pipeline, avoids impurity in valve pocket, to pile up, and relies on the press water that pumps that sealing surface is carried out flushing pollution discharge.
