Description
Technical field
The present invention relates to girdle filling mining technical field, particularly relate to a kind of filling pipeline and gate valve thereof.
Background technique
According to the statistics to State owned coal mine, under China's building, under Rail Highway, that water body presses down coal is serious, and a large amount of coal resources dare not be exploited at all.Whole nation pressure coal amount about 137.9 hundred million t, but along with socio-economic development, town size constantly expands, the construction in new mining area and new field with "nine squares", actual pressure coal amount also will far above this numeral.Along with improving constantly of coal mining level in recent years and exploitation scale, at present, in coal resources in China, medium-thickness seam reserves obviously reduce, and present day by day exhausted trend, therefore, the exploitation of girdle, for maintenance coal production, meets the current and long term growth of national economy and will play an important role to the demand side of coal.Verified in coal resources reserves in the whole nation, girdle accounts for more than 46%.Due to the congenital inferior position that girdle unit area coal amount is less, if exploited after adopting traditional resettlement, liberation girdle " three times " pressure coal, its overall cost will exceed standard greatly, therefore girdle " three times " filling mining is implemented, displacement coal resources, become the unique channel realizing girdle " three times " and exploit.
At present, in filling mining, due to paste body filling technique have connect top fully, casting resin compression ratio is little, casting resin preparation cost is lower etc. characteristic, thus used by increasing coal mining enterprise.But, when adopting paste body filling exploitation, particularly in the exploitation of girdle " three times " paste body filling, pinch aided process connect as indispensability of pipeline is larger on the impact of pack effectiveness.Because working space is narrow and small, delivery line is heavy, causes pipeline to be pinched and connects relative difficulty, seamless steel pipe not bullet change, pipeline are pinched and are connect frequently, cause pipeline to pinch and be connected in filling procedure the time occupying half nearly, so, pipeline pinch the key connecing and just more become restriction filling mining efficiency.
Therefore, how to provide a kind of be convenient to pinch connect, filling pipeline that pack effectiveness is high, be the current technical issues that need to address of those skilled in the art.
Summary of the invention
In view of this, the invention provides a kind of filling pipeline and gate valve thereof, so that pinching of pipeline connects, pack effectiveness can be improved.
In order to solve the problem, the invention provides a kind of gate valve of filling pipeline, comprise main line and the branch line being communicated in described main line sidewall, main line material feeding mouth, main line discharge port and branch line discharge port are equipped with for the flange with filling pipeline joint, one end that described main line is positioned at described main line discharge port is provided with main line cut-off flashboard, and described branch line is provided with branch line cut-off flashboard.
Preferably, in above-mentioned gate valve, described branch line welding is communicated in the sidewall of described main line.
Preferably, in above-mentioned gate valve, described flange is locking hood type flange.
Preferably, in above-mentioned gate valve, described main line cut-off flashboard and described branch line cut-off flashboard include two clamping plates and are clipped in the flashboard between two pieces of described clamping plate, and two pieces of described clamping plate are bolted fixing.
The gate valve of a kind of filling pipeline provided by the invention, comprise main line and the branch line being communicated in main line sidewall, main line material feeding mouth, main line discharge port and branch line discharge port are equipped with for the flange with filling pipeline joint, one end that main line is positioned at main line discharge port is provided with main line cut-off flashboard, and branch line is provided with branch line cut-off flashboard.
When carrying out paste body filling exploitation, by the main line material feeding mouth of this gate valve by Flange joint on the straight tube of filling pipeline, then, by main line discharge port or branch line discharge port by Flange joint on the filling pipeline of a certain segmentation, the switching to main line discharge port and branch line discharge port can be realized by control main line cut-off flashboard or branch line cut-off flashboard, thus the docking operation of another discharge port can be carried out wherein when a discharge port carries out filling, namely pinch in termination process at pipeline and also can carry out filling, therefore, Flange joint in this programme is convenient to pipeline and is pinched and connect, the switching mode of two discharge holes also improves pack effectiveness.
Present invention also offers a kind of filling pipeline, comprise the gate valve described in above-mentioned any one.The derivation of the beneficial effect that the derivation of the beneficial effect that this filling pipeline produces and above-mentioned gate valve bring is substantially similar, therefore repeats no more herein.
