Description
Technical Field
The utility model relates to a steel production facility technical field specifically is a high performance roll cooling water control system.
Background
When the roller in the rolling mill area works, the temperature can be continuously increased, and the continuity of the work can be kept only by cooling with cooling water; the cooling water pipe is generally in one-way automatic control without a monitoring device, and once a pneumatic valve fails, the cooling water of the roller is cut off, so that the service life of the roller is influenced; because of the cooling water pipe all buries the ground design and need pass towards the work area that the sediment ditch could reach the roll, for pneumatic valve installation and maintenance, the pneumatic valve is generally installed in towards the sediment ditch, and the environment is than poor, breaks down easily.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problem that a traditional pneumatic valve installed on a roller cooling water pipe is prone to failure is solved.
The utility model provides a high-performance roller cooling water control system, which comprises a valve well arranged on one side of a slag flushing ditch, wherein a plurality of cooling water pipes are arranged in the valve well, the cooling water pipes pass through the slag flushing ditch, and the water outlets of the cooling water pipes are arranged on the other side of the slag flushing ditch;
the cooling water pipe is sequentially provided with a first manual butterfly valve, a second manual butterfly valve, a first pneumatic butterfly valve, an electromagnetic flowmeter and a pressure gauge, wherein the first manual butterfly valve, the second manual butterfly valve, the first pneumatic butterfly valve, the electromagnetic flowmeter and the pressure gauge are arranged in the valve well, and a third manual butterfly valve and a second pneumatic butterfly valve are arranged in the valve well in parallel at two ends, back to back, of the first pneumatic butterfly valve.
The first manual butterfly valve is used for opening or closing the cooling water pipe and is generally in a normally open state; the second manual butterfly valve and the third manual butterfly valve are used for adjusting the flow of cooling water; the first pneumatic butterfly valve and the second pneumatic butterfly valve are used for opening or closing the cooling water pipe, the first pneumatic butterfly valve is normally open, and the second pneumatic butterfly valve is normally closed; the pressure gauge is used for measuring the water pressure in the cooling water pipe, and the electromagnetic flowmeter is used for measuring the flow of the cooling water; when first pneumatic butterfly valve takes place to damage and leads to the cooling water to cut off, the flow that the electromagnetic flow meter detected out diminishes, and the pneumatic butterfly valve of second is automatic to be opened, keeps the normal supply of cooling water, has solved the problem that the cooling water cuts off, and pneumatic butterfly valve and manual butterfly valve are installed in the valve well in addition, are difficult for taking place to damage.
Furthermore, the second manual butterfly valve and the two ends of the first manual butterfly valve which are opposite to each other are connected in parallel with a fourth manual butterfly valve which is located inside the valve well. The fourth manual butterfly valve is generally in a normally closed state, and when the first pneumatic butterfly valve and the second pneumatic butterfly valve are damaged, the fourth manual butterfly valve is opened, so that the replacement and the maintenance of the pneumatic butterfly valves are facilitated while the supply of cooling water is ensured.
