Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in the attached figure 1, the device comprises a regulating valve, a gate valve, a reducing short section and a regulating valve bypass pipeline.

The slag slurry material pipeline conveying device comprises the following components as shown in the attached drawings: sedimentation tank 17, sedimentation tank 17 bottom is fixed and is provided with sediment stuff pump 18, sediment stuff pump 18 is connected with reactor 16 through the main line, along the flow direction first gate valve 1 has set gradually on the main line, first ball valve 9 that drenches falls, first reducing nipple 2, second gate valve 3, the second ball valve 10 that drenches falls, governing valve 4, third gate valve 5, second reducing nipple 6, the third ball valve 11 that drenches falls, fourth gate valve 7, be provided with governing valve bypass 8 before first gate valve 1 and behind fourth gate valve 7, along the flow direction fifth gate valve 14 has set gradually on governing valve bypass 8, the fourth ball valve 12 that drenches falls, fifth ball valve 13 and sixth gate valve 15 that drenches.

The diameter of the pipeline of the regulating valve bypass 8 is designed to be the same as that of the main pipeline, so that normal operation can be guaranteed in emergency situations or during maintenance of main pipeline components. First gate valve 1 and fourth gate valve 7 are normally open gate valve, and fifth gate valve 14 and sixth gate valve 15 are normally closed gate valve, realize following the main line to the operation of governing valve bypass 8 through closing first gate valve 1 and fourth gate valve 7 and opening fifth gate valve 14 and sixth gate valve 15 simultaneously when emergency or main line part overhaul.

The first reducing short section 2 and the second reducing short section 6 respectively adopt the proportional design reducing of 2:1 and 1:2 to change the flow rate of the slag slurry along the flow direction, and the arrangement of the reducing short sections can form a buffer area at the position of the regulating valve 4, thereby avoiding the flushing of the regulating valve 4 caused by too high flow rate and the damage of the regulating valve.

In the device, the valve plate with small opening degree and the pipe wall after necking are most seriously scoured due to the slag slurry materials. Therefore, the first gate valve 1 arranged in front of the first reducing nipple 2 is in a normally open state, and the valve is only used in parking maintenance or emergency situations; all taps of the inverted-spraying ball valve are as short as possible (flanges can penetrate through bolts), and the inverted-spraying ball valve is horizontally arranged in design so as to reduce the blockage of slurry substances and facilitate dredging; the first reducing short section 2 and the second reducing short section 6 are provided with thickened pipe walls; the regulating valve 4 is kept at a large opening degree (the opening degree is more than 70%), the opening degree of the third gate valve 5 behind the regulating valve 4 is reduced, and a valve plate of the third gate valve 5 is easy to damage; to avoid clogging, the fifth gate valve 14 and the sixth gate valve 15 are arranged in the front and rear two positions on the pipeline of the bypass 8 of the regulating valve, and the distance from the main pipe is as short as possible.

When the main pipeline is blocked or the valve needs to be replaced, the method can be completed without stopping the vehicle according to the following steps, and the influence on normal production is avoided. The specific treatment method comprises the following steps:

1. the valve plate of the third gate valve 5 after the valve 4 is adjusted is seriously abraded, leakage occurs, and the valve needs to be replaced;

2. closing a fourth inverted-spraying ball valve 12 and a fifth inverted-spraying ball valve 13 on the regulating valve bypass 8, opening a front fifth gate valve 14 and a rear fifth gate valve 15, and manually regulating the flow;

3. closing the first gate valve 1 and the fourth gate valve 7 of the main pipeline;

4. opening all the reverse-spraying ball valves of the front main pipeline and the rear main pipeline of the regulating valve 4, setting the opening of the regulating valve 4 as 100 percent, and discharging liquid;

5. closing the second gate valve 3 in front of the regulating valve 4;

6. washing and cleaning the pipeline of the regulating valve 4;

7. and after the pipeline processing is finished, replacing the third gate valve 5.

8. After the third gate valve 5 is replaced, all the inverted-spraying ball valves on the main pipeline of the regulating valve 4 are closed;

9. opening a first gate valve 1, a second gate valve 3, a third gate valve 5 and a fourth gate valve 7 of a main pipeline of the regulating valve 4, and keeping the regulating valve 4 at a larger opening;

10. and closing a fifth gate valve 14 and a sixth gate valve 15 on the pipeline of the regulating valve bypass 8, and opening a fourth inverse-spraying ball valve 12 and a fifth inverse-spraying ball valve 13 to flush and replace the pipeline.

When the first reducing short section 2 leaks, the steps 1), 2), 3), 5), 6), 7), 8), 9) are repeated, and the operation is recovered again after the first reducing short section 2 is replaced.

Other component replacements are the same as described above.

By adopting the technical scheme, the problem of scouring and abrasion of the slurry material on the pipe fitting is effectively solved, the service lives of the flow regulating valve and the reducing nipple are prolonged, the parking loss is avoided, and the effect is ideal.
