Description

Technical Field

[0001] The utility model relates to the technical field of integrated valves, in particular to a directional drilling rig valve group. Background Art

[0002] The hydraulic control valve group of the directional drilling rig is a key component composed of multiple hydraulic valves, which plays a vital role in the mining of coal mine tunnels. Its structure includes directional control valves, flow control valves, pressure control valves, pilot valves and safety valves. These valve groups work together to achieve precise control of the flow, pressure and direction of the hydraulic oil in the hydraulic system, thereby driving the various actions of the directional drilling rig. The working principle is based on the principle of hydraulic transmission. When the hydraulic oil passes through different channels and valve cores in the valve body, the change of the valve core position adjusts the flow direction, pressure and flow of the hydraulic oil through mechanical or electromagnetic action to achieve control of the hydraulic system. However, the hydraulic control valve group at this stage does not add hydraulic pipelines for controlling the disassembly and assembly of drill rods and hydraulic pipelines for controlling the feed amount of drill rods. The two hydraulic control pipelines are still arranged and controlled separately. Since the operations of disassembling and assembling drill rods and adjusting the feed amount of drill rods require additional hydraulic pipelines and control systems, operators need to operate on different control panels, which increases the complexity and difficulty of the operation. Operators need to spend more time and energy to adjust and monitor these functions, resulting in low overall operation efficiency of coal mine tunnels. Utility Model Content

[0019] A pressure reducing valve group 3 5 and a relief valve with a handwheel 8 are installed on the other side of the surface of the integrated valve block 1.

A sequence valve 6 is installed on the surface of the integrated valve block 1 on one side of the pressure reducing valve group 1 2. A logic control valve group 7 is installed on the top of the integrated valve block 1. Various manual reversing valves such as the drilling manual reversing valve 12 and the clamp manual reversing valve 13 are responsible for controlling various functions of the directional drilling rig, such as brakes, drill pipe installation, rotation speed and drill pipe feed amount. The operator manually operates these reversing valves to adjust the flow direction and flow of hydraulic oil in the hydraulic system to achieve precise control of various functions of the directional drilling rig.

[0020] A balancing valve 9 and a shuttle valve group 10 are installed on the top of the integrated valve block 1 on the side of the feed manual reversing valve 18, and a hydraulically controlled one-way valve 11 is arranged on the surface of the integrated valve block 1 on the side of the pressure reducing valve group 3 5. The balancing valve 9 is responsible for balancing the pressure in the hydraulic system, and the hydraulically controlled one-way valve 11 is used to control the flow direction of the hydraulic oil in the hydraulic system to ensure the correct flow direction of the system when working, and to prevent unnecessary danger caused by the reverse pressure in the hydraulic system;

[0021] The pressure reducing valve group 1 2 includes a first pressure reducing valve 21, a second pressure reducing valve 22, a third pressure reducing valve 23, a fourth pressure reducing valve 24 and a fifth pressure reducing valve 25 installed on one side of the surface of the integrated valve block 1.

The pressure reducing valve group 2 4 includes a sixth pressure reducing valve 41, a seventh pressure reducing valve 42 and an eighth pressure reducing valve 43 installed on the other side of the surface of the integrated valve block 1. The pressure regulating range of the sixth pressure reducing valve 41, the seventh pressure reducing valve 42 and the eighth pressure reducing valve 43 is 10.5-315Bar;

[0022] The pressure reducing valve group three 5 includes a pressure reducing valve one 51 with a handwheel and a pressure reducing valve two 52 with a handwheel, which are arranged on one side of the surface of the integrated valve block 1. The pressure regulating range of the pressure reducing valve one 51 with a handwheel and the pressure reducing valve two 52 with a handwheel is 4-25Bar. The logic control valve group 7 includes a first logic valve 71, a second logic valve 72 and a third logic valve 73 installed on the top of the integrated valve block 1. The pressure regulating range of the handwheel relief valve 8 is 55-315Bar. The pressure regulating range of the balancing valve 9 is 70-280Bar, and the pilot ratio is 3:1.

[0023] The pressure reducing valves in the pressure reducing valve group 1 2, the pressure reducing valve group 3 5 and the pressure reducing valve group 2 4 release the excess flow when the system pressure exceeds the set value, thereby protecting the system from the influence of overpressure, while the pressure reducing valve with handwheel and the relief valve with handwheel 8 are responsible for adjusting the flow in the hydraulic system. The opening size of the valve port is adjusted by rotating the handwheel to control the flow in the hydraulic system, thereby realizing the adjustment of the feed speed of the actuators such as the drill bit;

[0024] The shuttle valve group 10 includes a first shuttle valve 101, a second shuttle valve 102, a fourth shuttle valve 104 and a fifth shuttle valve 105 installed on the top side of the integrated valve block 1.

[0025] When the embodiment of the present application is used, first, the pressure reducing valve group 1 2, the pressure reducing valve group 2 4 and the pressure reducing valve group 3 5 are used to control the pressure in the hydraulic system to ensure that the system works within a safe range, which is converted into a suitable pressure to drive various actuators, such as the advancement and rotation of the drill bit. The pressure reducing valve group can limit the maximum pressure of the hydraulic system, prevent the system from overpressure, and protect the safe operation of the system. The handwheel relief valve 8 adjusts the pressure of the hydraulic system to keep it within a stable range, thereby improving the working efficiency and stability of the system. During the operation of the directional drilling rig, it is necessary to control the rotation speed of the drill bit to adapt to the drilling operation under different formation conditions. The shuttle valve group 10 adjusts the rotation speed of the drill bit by controlling the hydraulic flow and pressure in the hydraulic system to achieve the desired working effect. The hydraulically controlled one-way valve 11 controls the flow direction of the hydraulic oil in the hydraulic system to control the flow direction of the hydraulic oil. Various manual reversing valves control the flow direction of the hydraulic oil in the hydraulic system through manual operation to control different functions. For example, the brake reversing valve It is used to control the opening and closing of the brake of the directional drilling rig, the drill pipe reversing valve is used to control the loading and unloading of the drill pipe, the rotation speed reversing valve is used to control the rotation speed of the drill bit, and the drill pipe feed amount reversing valve is used to control the feed amount of the drill pipe, etc. Among them, since the drill pipe manual reversing valve 16, the rotation speed manual reversing valve 17 and the feed manual reversing valve 18 are integrated on the integrated valve block 1, the operator can complete the operations of disassembling and assembling the drill pipe and adjusting the drill pipe feed amount on the same control panel, which not only reduces the complexity of the operation, but also improves the efficiency of the operation. All operations are completed on the same integrated valve block 1, and the operator can more easily understand and grasp the working status of the system. At this time, the maintenance personnel only need to pay attention to the integrated system of the hydraulic control valve group, which reduces the difficulty of management and maintenance.
