Description

Technical Field

[0001] This utility model relates to the field of gas technology, specifically to a ball valve for online gas pipeline applications. Background Technology

[0002] Gas pipelines are the core infrastructure for transporting natural gas, liquefied petroleum gas, and other gaseous gases. They can be categorized by purpose into long-distance gas transmission, city gas, and industrial pipelines. In terms of materials, outdoor pipelines typically use steel or high-density polyethylene pipes, while indoor pipelines commonly use brass or stainless steel pipes. Their construction involves design, laying, pressure testing, and acceptance procedures. Strict daily maintenance is required, with safety ensured through corrosion prevention and alarm systems. They are the "lifeline" for both residential and industrial gas supply.

[0003] Currently, when using gas pipelines, ball valves are required to control the opening and closing of the gas pipelines. In industrial pipeline installation scenarios such as gas pipelines, flange connection is a very common connection method. Ball valves also use flanges to connect with other pipelines. However, since pipelines and flange components often have a certain weight, multiple workers are usually required to work together, making the installation more troublesome and the overall installation efficiency lower, which is not conducive to the installation of ball valves. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a new technical solution:

[0024] Ball valve pipeline 1, the ball valve pipeline, serves as the main body of the device and is used to transport gas and provide a ball-throwing channel. The left and right ends are connected to the connecting pipeline 3 through a connecting structure, and the upper end is equipped with an electric controller 2.

[0025] The electric controller 2 is fixedly installed at the upper end of the ball valve pipeline 1 and is used to remotely control the opening and closing of the valve core inside the ball valve pipeline 1 to realize the automated control of operations such as throwing and collecting balls.

[0026] There are two connecting pipes 3, which are installed at the left and right ends of the ball valve pipe 1. They are extension pipes for gas transmission. Annular threaded connecting plates 7 are welded to the similar surfaces for connection with the ball valve pipe 1.

[0027] There are two mounting slots 4, which are opened on the left and right surfaces of the ball valve pipe 1 to provide rotational mounting space for the connecting plate 5, allowing the connecting plate 5 to rotate flexibly within the slots;

[0028] There are two connecting plates 5, which are rotatably installed inside the two mounting slots 4. The connecting holes 6 are opened inside. Through the threaded connection with the annular threaded connecting plate 7, the ball valve pipe 1 and the connecting pipe 3 are initially fixed.

[0029] There are two connection holes 6, which are opened inside the two connection plates 5. The inner wall is threaded and used to connect with the annular threaded connection plate 7 on the connecting pipe 3, providing pre-fixation for pipe docking.

[0030] There are two annular threaded connecting plates 7, which are welded to the similar surfaces of the two connecting pipes 3. The outer side is threaded and can be threaded into the corresponding connecting hole 6 to connect with the connecting plate 5, so as to achieve the initial fixation of the connecting pipe 3 and the ball valve pipe 1.

[0031] There are two threaded holes 8, which are opened on the front surface of the ball valve pipe 1 and extend through the rear end into the corresponding mounting groove 4 to provide a threaded mounting position for the tightening bolt 9.

[0032] There are two tightening bolts 9, with threads installed inside the two threaded holes 8. When rotated, they can push the anti-slip pad 10 to move, which is used to fix or release the connecting plate 5 in conjunction with the anti-slip pad 10.

[0033] There are two anti-slip pads 10, which are fixedly installed at the rear end of the two tightening bolts 9. They cooperate with the tightening bolts 9 to fix the connecting plate 5 by increasing the friction and preventing it from shifting during the docking process.

[0034] The handle 11 is fixedly connected to the front surface of the ball valve pipeline 1, providing a force point for the handling of the device and facilitating the manual transfer of the ball valve pipeline 1;

[0035] The rubber pad 12 is fixedly installed on the outer surface of the handle 11 to increase the comfort and friction of the hand grip and prevent slippage during handling.

[0036] Furthermore, firstly, using the handle 11 with rubber pad 12 on the front surface of the ball valve pipe 1, the device is moved to the installation position on the gas pipeline. Then, the tightening bolt 9 inside the threaded hole 8 on the front surface of the ball valve pipe 1 is rotated, pushing the anti-slip pad 10 at the rear end of the bolt to tightly fit against the connecting plate 5 in the mounting groove 4. Friction force is used to fix the connecting plate 5 in its current position, preventing it from rotating arbitrarily during subsequent operations. The device position is then adjusted so that the connecting holes 6 on the connecting plates 5 fixed on both sides of the ball valve pipe 1 are precisely aligned with the annular threaded connecting plate 7 welded to the end of the connecting pipe 3. Rotate the ball valve pipe 1 and screw the annular threaded connecting plate 7 into the corresponding connecting hole 6 to complete the initial threaded fixation of the ball valve pipe 1 and the connecting pipe 3, and realize the pre-connection positioning of the two. Rotate the tightening bolt 9 in the opposite direction to drive the anti-slip pad 10 to disengage from the connecting plate 5, and release the fixation restriction on the connecting plate 5. At this time, the ball valve pipe 1 can rotate freely around the threaded connection part. Rotate the ball valve pipe 1 to make its own flange precisely aligned with the flange on the connecting pipe 3. Then tighten the two sets of flanges with bolts to complete the final installation and fixation of the ball valve pipe 1 and the connecting pipe 3.

[0037] By setting the connecting plate 5 and the annular threaded connecting plate 7, the connecting hole 6 is aligned with the annular threaded connecting plate 7. The threaded pre-connection structure provides preliminary positioning and temporary fixation for the ball valve pipeline 1 and the connecting pipeline 3, replacing the manual support alignment during traditional docking, reducing the operational difficulty of flange alignment, and thus improving the installation efficiency of the ball valve.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
