Detailed Description
The invention is further described with reference to the figures and the specific embodiments.
Example 1: as shown in fig. 1-5, the hydraulic punching steering valve for the mine comprises a drill bit joint 1, the hydraulic punching steering valve body 2 is of a strip-shaped cylindrical cavity structure, the drill bit connector 1 is arranged at one end of the hydraulic punching steering valve body 2, the other end of the hydraulic punching steering valve body 2 is provided with a threaded blind hole 8 connected with a drill rod, a communicated low-pressure water flow channel 7 is arranged inside the hydraulic punching steering valve body 2 along the length direction of the hydraulic punching steering valve body, a high-pressure water flow channel 3 communicated with the low-pressure water flow channel 7 is radially arranged, a high-pressure water jet device 4 is installed inside the high-pressure water flow channel 3, a conical part 9 with two symmetrical ends is arranged at the position, right opposite to the low-pressure water flow channel 7, of the high-pressure water flow channel 3, the steel ball 5 is placed inside the conical part 9, a reset spring 6 is arranged on one side, close to the.
Preferably, the high-pressure water flow channels 3 are provided with a plurality of (4), and each high-pressure water flow channel 3 is internally provided with one high-pressure water jet device 4, so that the scouring efficiency of the gas extraction cavity can be improved.
The use principle is as follows: the mining hydraulic punching steering valve body 2 is connected with a drill bit through a 94mm drill bit connector, a high-pressure water flow channel 3 and a low-pressure water flow channel 7 are arranged inside the hydraulic punching steering valve body 2, the low-pressure water flow channel leads to the drill bit, and the high-pressure water flow channel leads to a high-pressure water perforation, as shown in figure 2, when the water pressure is smaller than 8Mpa, a high-strength spring 6 does not work, a steel ball 5 stays at the center of the high-pressure water perforation, when the punching water pressure is larger than 8Mpa, the steel ball 5 compresses a reset spring 6, the channel leading to the drill bit in the hydraulic punching steering valve body 2 is blocked by the steel ball 5, high-pressure water is pressed into a high-pressure water jet device 4 to form high-pressure water flow to be.
The novel mining hydraulic punching steering valve is provided by combining the special construction environment of a mine and combining the characteristics of good coal body softening effect, high efficiency, energy conservation, environmental protection and good directivity of high and low water jet flow, and the safety, high efficiency and economy concepts.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention, and therefore, the scope of the present invention should be determined by the scope of the claims.
