A bypass pipeline is connected with a primary steam source end of the secondary steam pipeline, an output end of the bypass pipeline and an output end of the secondary steam pipeline are gathered with each other and are connected to a steam source end of steel cold-rolling equipment, and a gate valve is arranged on the bypass pipeline; a drainage valve is an electric control valve, a temporary water storage tank is mounted on an inlet side of the drainage valve, hydraulic pressure gauges with electric contacts are arranged in the temporary water storage tank, and the electric contacts of the hydraulic pressure gauges are arranged in a control circuit of the electric control valve. The steel cold-rolling steam supply system has the advantages that the steel cold-rolling steam supply system is additionally provided with a bypass pipeline supply system by the aid of existing valves of temperature and pressure reducing devices, the bypass pipeline supply system can be started under the condition of insufficient pressures of steams of sources, accordingly, the problem of steam circulation obstruction due to throttle orifice plates can be thoroughly solved, secondary pressure reduction can be prevented, and normal running of equipment of production units can be guaranteed.
Description
Technical field
The present invention relates to a kind of steel industry cold-rolling equipment, specifically a kind of cold rolling steam feed system of iron and steel.
Background technology
Reducing-and-cooling plant is widely used in steel industry cold-rolling process, initial steam (the P=1.2Mpa sent here by power plant, T=240 DEG C) initially enter point two-way after gas-distributing cylinder balance adjustment and enter in reducing-and-cooling plant, after desuperheat, decompression, obtain indirect steam supply each user use by steam pipework.
Existing a few seat height temperature reducing-and-cooling plant, supplies steam pressure for regulating station；Mentality of designing is power plant supply steam pressure fluctuation range is 1.2Mpa-1.0Mpa, after secondary pressure, pressure is adjusted downward to about 0.45Mpa-0.8Mpa, to meet each rolling unit Production requirement, if but steam source pressure feed is not enough, then due to the resistance of restricting orifice, this temperature reducing and pressure reducing system can cause that the secondary that steam supplies declines, and the equipment of serious threat rolling unit runs and product quality.
Summary of the invention
There is the equipment of the not enough serious threat rolling unit of supply for iron and steel cold-rolling process in prior art with steam source pressure to run and the defect such as product quality, the technical problem to be solved in the present invention is to provide and a kind of prevents secondary pressure, ensures to produce the cold rolling steam feed system that unit equipment is properly functioning.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
The cold rolling steam feed system of one iron and steel of the present invention, having indirect steam pipeline, the outfan at a vapour source connecting bypass pipeline of indirect steam pipeline, the outfan of bypass line and indirect steam pipeline converges, being connected to the vapour source of iron and steel cold-rolling equipment, bypass line is provided with gate valve.
State bypass line and be many groups, arrange parallel.
Minimum point at bypass line sets drain valve.
Drain valve adopts motor-operated control valve, installs temporary storage tank at drain valve inlet side, is provided with dress electric contact hydraulic pressure gauge in temporary storage tank, and the electric contact of this hydraulic pressure gauge is located in the control loop of motor-operated control valve.
The invention have the advantages that and advantage:
1. the present invention utilizes existing reducing-and-cooling plant valve, sets up bypass line feed system, in the steam pressure deficiency situation of source, start bypass line feed system, thoroughly solve the obstruction that steam is circulated by restricting orifice, it is prevented that secondary pressure, it is ensured that produce unit equipment properly functioning.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Wherein, 1 is bypass line, and 2 is gate valve, and 3 is platform, and 4 is bracket, and 5 is indirect steam pipeline, and 6 is air relief valve, and 7 is the first electrodynamic valve, and 8 is the second electrodynamic valve, and 9 is former pipeline gate valve.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further elaborated.
As shown in Figure 1, the cold rolling steam feed system of one iron and steel of the present invention, there is indirect steam pipeline, a vapour source connecting bypass pipeline 1 at indirect steam pipeline, the outfan of the outfan of bypass line 1 and indirect steam pipeline 5 converges, being connected to the vapour source of iron and steel cold-rolling equipment, bypass line 1 is provided with gate valve 2.
The present invention utilizes existing reducing-and-cooling plant valve, sets up bypass line feed system, in the steam pressure deficiency situation of source, start bypass line feed system, thoroughly solving the obstruction that steam is circulated by restricting orifice, it is prevented that secondary pressure, impact produces unit equipment and runs and product quality.
As seen from Figure 1, if not setting up steam by-pass pipeline 1, power plant supply steam must flow through temperature reducing and pressure reducing system and carries；After setting up bypass line system, if meeting power plant steam pressure deficiency, then can start bypass line 1, it is to avoid air relief valve secondary pressure, causing that discharge pressure wretched insufficiency affects unit and produces.
The present invention is while setting up bypass line system, and original pressure and temperature reducing function also should retain；In the present embodiment, there are five seat height temperature reducing-and-cooling plants, supply steam pressure for regulating station, utilize two set induction systems can complete the normal pressure supply producing unit.Due to the restriction of on-the-spot place, the present embodiment overlaps bypass lines by two and is located at above indirect steam pipeline by paralell, and the gate valve 2 of bypass line 1 is also located on this platform, is come from ground by bracket 4 and carries out manually maintenance platform or operate.
The present invention sets drain valve in the minimum point of bypass line.After setting up bypass line system, bypass line hydrops need to be removed in time, if hydrops enters vapour system and can cause that pipeline vibrations strengthen, causes that pipeline portions interface ruptures, influential system steam pressure；The present invention processes this problem by setting up drain valve for bypass line low spot.Drain valve is manually controllable, rule of thumb, gets final product hand-actuated to certain time.May be used without motor-operated control valve, at drain valve inlet side, temporary storage tank is installed, dress electric contact hydraulic pressure gauge it is provided with in temporary storage tank, the electric contact of this hydraulic pressure gauge is located in the control loop of motor-operated control valve, so when in temporary storage tank, water level is sufficiently high, electric contact hydraulic pressure gauge pressure is enough, connects electric contact, then opens motor-operated control valve and be released in water system pipeline by hydrops.
