Description

Technical Field

[0001] The utility model belongs to the technical field of mining equipment and relates to a water guide valve for filling pipelines in underground mines. Background Art

[0002] In mines that adopt the mechanized downward layered horizontal approach cementation filling method, the filling of the underground goaf is generally divided into three processes: bottom filling, secondary filling and top filling. Before the filling process begins, the filling pipeline needs to be drained and lubricated with clean water for 2 to 3 minutes to ensure that the filling pipeline is unobstructed. After the filling is completed, the filling pipeline needs to be cleaned with clean water for 8 to 12 minutes to ensure that the slurry in the filling pipeline is clean.

[0003] As the mine continues to be mined deeper and deeper, the filling pipeline is laid longer, and the start and stop of filling will cause a large amount of pipe lubrication and pipe washing water to enter the mining area, which can easily cause the filling slurry to segregate to form a sand roof, reduce the concentration of the filling slurry, and thus affect the strength of the filling body, and may also cause the board wall collapse accident due to excessive filling and top connection. In addition, when the goaf is top connected, a large amount of pipe washing water used to clean the filling pipeline will squeeze the slurry that has entered the access filling top connection from the board wall exhaust port, resulting in the problem of no top connection, which has a serious impact on the safety of adjacent access mining. At the same time, the overflowing filling slurry mixed with the ore will cause ore depletion and affect the ore quality. The ore containing filling slurry entering the chute is likely to cause chute blockage and affect normal production. Utility Model Content

[0004] The utility model aims to provide a water guide valve for underground mine filling pipes to solve the problems of excessive filling top connection and reduced filling slurry concentration caused by the cleaning water of the underground mine filling pipes entering the mining area.

[0005] To this end, the utility model adopts the following technical solutions:

[0006] A water diversion valve for filling pipes in underground mines, comprising a valve body, the valve body being in a cavity shape, and a rotatable valve plate assembly being arranged inside the valve body, the valve plate assembly comprising a rocker, the rocker being in contact with an inner wall of the valve body through a valve stem, a first valve disc and a second valve disc being arranged on both sides of the rocker, the first valve disc being fixedly connected to the rocker through a first bolt, and the second valve disc being fixedly connected to the rocker through a second bolt;

[0007] The valve body is provided with a first opening, a second opening and a third opening, wherein a first sealing gasket is provided inside the valve body near the first opening and a second sealing gasket is provided near the second opening, and both the first sealing gasket and the second sealing gasket are used to limit the rotatable valve plate assembly.

[0008] Furthermore, the rocker includes a first rod body and a second rod body, and the connection angle between the two is 110-130 degrees, and a socket is provided in the middle of the first rod body.

[0009] Furthermore, the first rod body has arc-shaped sides, a semicircular bottom, and a straight-sided top, and the width of the first rod body increases from top to bottom; the second rod body is a straight rod, and its size is 13cm~15cm.

[0010] Furthermore, the first valve disc includes a second rod body, both ends of the second rod body are provided with a first protrusion, the three form a U-shape, the size of the second rod body is 18cm~22cm, and the size of the first protrusion is 1cm~2cm.

[0011] Furthermore, the second valve disc includes a third rod body, and both ends of the third rod body are provided with second protrusions, and the three form a U-shape. The size of the third rod body is 14cm~16cm, and the size of the second protrusion is 0.6cm~0.8cm.

[0012] Furthermore, a lifting ring is provided at the bottom of the valve body.

[0013] The beneficial effects of the utility model are:

[0014] The utility model drives the valve plate assembly to different positions by rotating the rocker, thereby determining the flow direction of filling mortar or pipe washing water passing through the valve body, which can avoid the problem of filling slurry being segregated to form a sand top plate after a large amount of pipe lubricating water, pipe washing water, etc. enters the mining field, and can reduce the concentration of filling slurry and solve the problem of low filling top connection rate.
