Description

Conversion structure of gate valve of underground mine water pump pipeline

technical field

The utility model relates to the field of underground mine water pump equipment, in particular to an underground mine water pump pipeline gate valve conversion structure.

Background technique

The diameter of the drainage pipe should match the capacity of the pump and the total designed drainage capacity. The selection of the water pump should be determined according to the comprehensive analysis of lift, displacement and matching pipe diameter, as well as motor type and voltage. Generally, the main drainage equipment in underground mines should include working water pumps, standby water pumps and maintenance water pumps. The working water pump should be able to discharge the normal water influx of one day and night within 20 hours; the working water pump and the standby water pump should be able to discharge the maximum designed water inflow volume for one day and night within 20 hours. The capacity of the standby water pump is not less than 50% of the capacity of the working water pump; the capacity of the maintenance water pump is not less than 25% of the capacity of the working water pump. As far as the working drainage pipeline and the standby drainage pipeline should be set up, the general working drainage pipeline should be able to cooperate with the working water pump to discharge the normal water inflow in one day and night within 20 hours; all the drainage pipelines should be able to cooperate with the working water pump and the standby water pump to discharge within 20 hours. The maximum water inflow is designed for one day and night. When any one of the drainage pipelines is overhauled, the other drainage pipelines should be able to complete the normal drainage tasks.

However, the existing drainage system is often difficult to solve when the working drainage pipeline or any pipeline of the standby drainage pipeline has accidental shutdown failure and accidental damage to the pipeline, as well as the danger of submerged water pumps caused by insufficient sump capacity in the rainy season. It is difficult to effectively ensure the smooth progress of drainage.

Utility model content

The technical problem to be solved by the utility model is to provide a gate valve switching structure of the underground mine water pump pipeline which can flexibly realize the drainage adjustment, thereby ensuring the smooth drainage of the underground mine water pump.

The technical solution adopted by the present utility model to solve the technical problem is as follows: a gate valve conversion structure of an underground mine water pump pipeline includes a first pipeline, and one end of the first pipeline is provided with a first water pump, including a second pipeline, and the second pipeline One end is provided with a second water pump, and the first pipeline and the second pipeline are connected through a connecting pipe, wherein one end of the connecting pipe is connected with the first pipeline through the first pipeline electrical conversion valve, and the other end of the connecting pipe is electrically connected through the second pipeline. The switching valve communicates with the second conduit.

Further, the first pipeline electrical switching valve is a three-way switching gate valve.

Further, the second pipeline electrical switching valve is a three-way switching gate valve.

Further, the water inlet of the first water pump and the water inlet of the second water pump are arranged on the same horizontal plane.

The beneficial effect of the utility model is: in actual use, due to the parallel connection between the first pipeline and the second pipeline, when any pipeline has accidental shutdown failure and accidental damage to the pipeline, or the water tank capacity is insufficient in the rainy season. When the water pump is in danger of being submerged, it can be dealt with by flexible switching of the first pipeline electric conversion valve and the second pipeline electric conversion valve, so as to realize emergency movement or increase the drainage of the water pump. At the same time, the gate valve conversion structure of the underground mine water pump pipeline can also ensure that the underground drainage facilities can be used normally under any circumstances, and the drainage capacity will not be reduced. The utility model is especially suitable for the underground mine drainage system.

As shown in FIG. 1 , the gate valve conversion structure of the underground mine water pump pipeline includes a first pipeline 11, one end of the first pipeline 11 is provided with the first water pump 1, and includes a second pipeline 21, and one end of the second pipeline 21 is provided with a In the second water pump 2 , the first pipeline 11 and the second pipeline 21 are connected through a connecting pipe 3 , wherein one end of the connecting pipe 3 is connected with the first pipeline 11 through the first pipeline electrical conversion valve 12 , and the other end of the connecting pipe 3 is connected with the first pipeline 11 . The electrical switching valve 22 communicates with the second pipeline 21 through the second pipeline.

In actual use, normal drainage requirements can generally be ensured through the first pipeline 11 . At this time, the drain water is conveyed through the first pipeline 11 through the first pipeline electrical switching valve 12 . When the transmission failure of the first pipeline 11 occurs or a large amount of water gushing occurs in the mine silo, there is a danger of submerging the water pump and the water pump at the lowest position is flooded, then the second pipeline electric conversion valve 22 and the first pipeline electric conversion valve 12 can be adjusted by adjusting , to realize the switching of the water flow between the first pipeline 11 and the second pipeline 21 , thereby ensuring the flexibility of the water flow transportation and better adapting to various production needs. Generally, in order to realize the above-mentioned function of flexible adjustment, it is preferable that the first pipeline electrical switching valve 12 is a three-way switching gate valve. At the same time, it may also be preferred that the second pipeline electrical switching valve 22 is a three-way switching gate valve.

In order to ensure the stability of pumped water, preferably, the water inlet of the first water pump 1 and the water inlet of the second water pump 2 are arranged on the same horizontal plane.

The utility model solves the problem of poor flexibility of the original drainage by making minor modifications to the existing structure. Flexible adjustments can be made at one time to ensure smooth production. The technical advantage of the utility model is obvious, and the market promotion prospect is very broad.
