Embodiment 1

[0054] Embodiment 1: as figure 1 , The rotating shaft and the valve body adopt multiple seals to ensure that there will be no leakage under high pressure. The rotating shaft and gear parts are connected by a square shaft to increase the strength. The gear and rack transmission is relatively safe and reliable.

[0055] Figure 4 and Figure 5 The structure of the rotation switch is shown, and the communication between the A feed port and the C discharge port, and the communication between the A feed port and the B discharge port can be realized through a 90° rotation.

[0056] image 3 It shows the transmission of the gear and the rack. The rack is driven by the cylinder to drive the gear and the rotating shaft to rotate, so as to realize the channel switching. The No. 1 hydraulic cylinder and the No. 4 hydraulic cylinder are in one group, and the No. 2 hydraulic cylinder and the No. 3 hydraulic cylinder are one The group realizes the synchronous promotion of the rack.

Abstract

The invention discloses a rotatable material distributing valve device for coal mine gangue paste body filling and an operation method and belongs to the field of coal mine gangue paste body filling.The rotatable material distributing valve device comprises a rotating valve, a mining reversing valve and a valve hydraulic driving device; the mining reversing valve and the valve hydraulic driving device are connected to the upper end of the rotating valve, and the mining reversing valve is located on one side of the valve hydraulic driving device; the mining reversing valve is used for drivingthe rotating valve for reversing by manually connecting the valve hydraulic driving device; or an electromagnetic valve of the valve hydraulic driving device is used for connecting the valve hydraulicdriving device to drive the rotating valve for rotating and reversing. The rotatable material distributing valve device has the advantages of being compact in structure, resistant to abrasion, resistant to high pressure, good in sealing performance, convenient to disassemble, assemble and maintain, easy to operate and capable of saving labor. Firstly, in-site and remote control is achieved, in-site overhauling and remote control of a center control room are facilitated; secondly, under a high-pressure work condition, leakage is also avoided; thirdly, the structure is simple, the using amountof parts is small, and the fault rate is greatly reduced; and fourthly, using in a narrow and small space can be achieved, installing is convenient, and unattended operation is achieved.

Description

technical field [0001] The invention relates to the field of coal mine gangue paste filling, in particular to a coal mine gangue paste filling rotatable distributing valve device and an operating method. Background technique [0002] With the increasing demand for backfilling in coal mines, in the process of underground paste filling, due to the large number of backfilling working faces and limited space, especially in the case of fully mechanized mining, the space at the support is narrow, which requires a kind of It is a device to quickly switch the direction of material distribution, and since the pressure of the filling pipeline must reach 10MPa, this requires a device that can withstand high pressure and at the same time meet the requirements of large diameter, not afraid of wear, compact structure, easy operation, convenient disassembly and maintenance, etc. installation. [0003] At present, there is no pipe valve device on the market that can meet the reversing requ...
