Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an arrow-shaped pressure relief check valve for drilling tools. Background Art

[0002] In oil and gas drilling operations, the drill bit arrow-shaped pressure relief check valve is a key well control device. Its main function is to prevent the backflow of high-pressure fluid in the well and ensure the safety and smooth progress of drilling operations. However, in actual use, due to various reasons (such as material aging, sealing surface wear, improper operation, etc.), the check valve may leak. Traditional detection methods often rely on manual inspections, which is not only inefficient, but also difficult to detect leaks in the first place, bringing potential safety hazards to drilling operations.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-3The utility model provides a technical solution: a drilling tool arrow-shaped pressure relief check valve, comprising a check valve 1, a sleeve ring 2 is sleeved on both sides of the outer wall of the check valve 1, and clamping holes 3 are symmetrically opened on both ends of the inner wall of the sleeve ring 2. Rubber clamping balls 4 are installed on both sides of the upper and lower ends of the check valve 1. A first connecting seat 5 is arranged at the bottom end of the sleeve ring 2. One end of the second connecting seat 6 is threadedly connected to the inner cavity of the first connecting seat 5. The other end of the second connecting seat 6 extends out of the outer wall of the first connecting seat 5 and is rotatably connected to a support rod 7 through a bearing. A box body 8 is installed at the bottom end of the support rod 7. A battery 9, a liquid level sensor 10 and a buzzer 11 are installed on the top of the inner cavity of the box body 8 from left to right in sequence. A cover body 12 is arranged at the bottom end of the box body 8.

[0016] As a preferred solution, further, the clamping hole 3 and the rubber clamping ball 4 are clamped with each other.

[0017] As a preferred solution, further, the battery 9, the liquid level sensor 10 and the buzzer 11 are electrically connected to each other.

[0018] As a preferred solution, further, the cover 12 is located directly below the battery 9, the liquid level sensor 10 and the buzzer 11, and opening the cover 12 can facilitate maintenance of the electrical components.

[0019] As a preferred solution, further, an anti-skid edge is provided on the outer wall of the second connecting seat 6, and the second connecting seat 6 can be rotated better through the anti-skid edge.

[0020] The electrical components mentioned in this solution are all existing technologies, and their models are only one of them. As long as the electrical components can meet the requirements of this solution, they can be used.

[0021] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control. The specific work is as follows.

[0022] When leakage occurs at the connection ports on the left and right sides of the check valve 1 or at the top cover thereof, the leaked liquid will drip downward into the inner cavity of the box body 8, and the box body 8 can collect the leaked liquid to avoid spilling it on the ground. When the liquid level sensor 10 detects the accumulation of liquid in the box body 8, it proves that leakage occurs somewhere on the check valve 1. At this time, the buzzer 11 immediately makes a sound to remind the staff to pay attention; flip the box body 8 with force, and the box body 8 will drive all the structural parts on the box body 8 to flip together. During this process, the rubber card ball 4 will be squeezed and separated from the inner cavity of the card hole 3. When the box body 8 is flipped to the top of the check valve 1, the rubber card ball 4 will be re-entered into the inner cavity of the card hole 3. By the mutual clamping between the card hole 3 and the rubber card ball 4, the position of the box body 8 can be fixed. When the check valve 1 is in the process of transportation, the box body 8 above the check valve 1 can protect it to avoid collision; rotate the second connecting seat 6, and the second connecting seat 6 will gradually rotate out of the inner cavity of the first connecting seat 5, so that the box body 8 can be disassembled and replaced;

[0023] The device has a simple structure and a reasonable design. It can detect in real time whether the valve body is leaking. Compared with traditional manual inspections, the use of sensors to detect liquid leakage is undoubtedly more accurate and convenient, and can be discovered at the first time, which greatly improves the overall safety and is easy to use. In addition, when transporting the valve body, the box body 8 can be flipped over to the top of the check valve 1 to protect the check valve 1 and reduce damage caused by bumps. It is highly practical and suitable for promotion.
