Abstract
The utility model relates to a device for balancing the pressure of steel rolling circulating water. According to the device for balancing the pressure of the steel rolling circulating water, one end of a steel rolling circulating cooling water pump is communicated with a cooling water well, the other end of the steel rolling circulating cooling water pump is communicated with a steel rolling circulating cooling water pipeline, a water outlet main valve and a rolling mill, a water drainage pipe which is communicated with the cooling water tank is fixed to the side, close to the steel rolling circulating cooling water pump, of the water outlet main valve, and a water drainage valve is fixed to the water drainage pipe. The device for balancing the pressure of the steel rolling circulating water is simple in structure, and balancing of the pressure of the steel rolling circulating water can be effectively achieved.
Description
Technical field
The utility model relates to the hydraulic balance device of a kind of hydraulic balance device, particularly steel rolling circulating water.
Background technique
Steel rolling circulating pump room is responsible for the task of securing an adequate supply of steel rolling mill's recirculated cooling water.But in process of production, steel rolling is due to transient service tasks such as roll changes, and often Temporarily Closed total pipeline upper water-out total valve, causes water pump sultry running, causes the very big safe operation hidden danger of water pump.If water pump upper cover is suppressed out, can cause the severe accident of water logging pump house, and then steel rolling can not be resumed production for several days.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of steel rolling circulating water hydraulic balance device, and it is simple in structure, can effectively solve the hydraulic balance problem of steel rolling circulating water.
The technical scheme in the invention for solving the technical problem is: steel rolling recirculated cooling water water pump one end communicates with cooling water well, and the other end communicates with steel rolling mill by steel rolling recirculated cooling water pipeline, water outlet main valve; Described water outlet main valve is near the fixing drain pipe communicating with cooling water well of steel rolling recirculated cooling water water pump side, fixing drain valve on drain pipe.
The utility model is simple in structure, can effectively solve the hydraulic balance problem of steel rolling circulating water.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the utility model first embodiment's schematic diagram,
Fig. 2 is the utility model second embodiment's schematic diagram.
Embodiment
As shown in Figure 1, steel rolling recirculated cooling water water pump 2 one end communicate with cooling water well, and the other end communicates with steel rolling mill by steel rolling recirculated cooling water pipeline 5, water outlet main valve 4; Described water outlet main valve 4 is near the fixing drain pipe 6 communicating with cooling water well of steel rolling recirculated cooling water water pump 2 sides, fixing drain valve on drain pipe 6.
Described drain valve is manually operated valve or solenoid valve 3, as shown in Figure 1.
Described drain valve is relief valve 7, as shown in Figure 2.Realize automatically and controlling.
Described water outlet main valve 4 is near the fixing everguard alarm 8 of steel rolling recirculated cooling water water pump 2 sides, and when circulating water pressure exceeds design load, alarm, opens manually operated valve or solenoid valve 3 in time.As shown in Figure 1.
