Description

Technical Field

[0001] This utility model relates to the field of valve casting technology, and in particular to a valve casting for pressure-resistant pipelines. Background Technology

[0002] Pressure-resistant pipelines typically refer to pipeline systems designed to withstand both external and internal pressure. These pipelines are widely used in various industrial sectors, such as oil, natural gas, chemical, water supply, and sewer systems. Valve castings for pressure-resistant pipelines are used to ensure the proper functioning of the pipeline system, including controlling fluid flow, regulating flow rate, preventing backflow, and completely shutting off fluid flow when necessary.

[0003] However, some valves at present, when closed, may deform under water pressure due to their large internal space, affecting their sealing performance and service life. Therefore, improvements are urgently needed. Utility Model Content

One of the movable plates is fixedly connected to the first filling column, and the other movable plate is fixedly connected to the second filling column.

[0019] Preferably, the rotating mechanism includes:

[0020] The first rotating rod is fixedly mounted on the ball valve;

[0021] A rotating plate is mounted on the first rotating rod and is fixedly connected to the first rotating rod.

[0022] Preferably, the support mechanism includes:

[0042] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a pressure-resistant pipeline valve casting.

[0043] A pressure-resistant pipeline valve casting includes a valve body 1, a ball valve 2, and a mounting hole 3. The ball valve 2 has a drain groove 19 for draining residual water from the ball valve 2 when the first filling column 6 and the second filling column 7 move into the internal space of the ball valve 2. An elastic sealing ring 20 is provided inside the valve body 1, located between the valve body 1 and the ball valve 2. The elastic sealing ring 20 serves to seal and prevent water leakage from the ball valve 2 during rotation. It also includes:

[0044] There are two fixed shells 4, which are symmetrically fixed on the valve body 1. The fixed shells 4 are provided with two limiting movement grooves 17 to limit the movement position of the moving plate 11.

[0045] A U-shaped fixing plate 5 is fixedly mounted on the fixing shell 4; the U-shaped fixing plate 5 is provided with a rotation space 16 for providing working space for the rotation mechanism;

[0046] The first filling column 6 is disposed inside the fixed shell 4 and is slidably connected to the fixed shell 4. It is used to fill the internal channel of the ball valve 2, reduce the internal space of the ball valve 2, and prevent the ball valve 2 from deforming under pressure.

[0047] The second filling column 7 is slidably disposed on the fixed shell 4; it is used to fill the space inside the ball valve 2 and prevent the ball valve 2 from deforming.

[0048] The sealing plate 8 is fixedly installed on the second filling column 7; it serves to seal and prevent water from the drain trough 19 from flowing into the fixed shell 4.

[0049] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, a rotating mechanism is disposed on the U-shaped fixing plate 5, for moving the first filling column 6 and the second filling column 7; the rotating mechanism includes:

[0050] A bidirectional screw 9 is rotatably mounted on the U-shaped fixing plate 5;

[0051] Rotary key 10 is fixedly mounted on the bidirectional screw 9;

[0052] Two movable plates 11 are provided, and the two movable plates 11 are symmetrically arranged on the bidirectional screw 9. The movable plates 11 are threadedly connected to the bidirectional screw 9. One of the movable plates 11 is fixedly connected to the first filling column 6, and the other movable plate 11 is fixedly connected to the second filling column 7.

[0053] When the ball valve 2 is closed, the key 10 is manually rotated. The key 10 rotates the double screw 9, which in turn drives the two moving plates 11 to move closer to each other. One moving plate 11 moves the first filling column 6, and the other moving plate 11 moves the second filling column 7. This allows the first filling column 6 and the second filling column 7 to fill the space inside the ball valve 2. When the ball valve 2 is under pressure, this disperses some of the pressure, thus preventing the ball valve 2 from deforming.

[0054] Reference Figure 1 , Figure 2 and Figure 5 In a preferred embodiment, a rotating mechanism is disposed on the ball valve 2 for driving the ball valve 2 to rotate; the rotating mechanism includes:

[0055] The first rotating rod 12 is fixedly mounted on the ball valve 2; the first rotating rod 12 is provided with a plurality of spring washers 18, which are slidably connected to the first rotating rod 12 and located between the valve body 1 and the rotating plate 13, to stabilize the rotation position of the rotating plate 13 and ensure stability during operation.

[0056] A rotating plate 13 is disposed on the first rotating rod 12 and is fixedly connected to the first rotating rod 12.

[0057] During operation, rotating the key 10 drives the double screw 9 to rotate, which in turn drives the moving plate 11 to move away from each other, thereby moving the first filling column 6 and the second filling column 7 out of the internal space of the ball valve 2. By manually rotating the rotating plate 13, the rotating plate 13 drives the first rotating rod 12 to rotate, which in turn drives the ball valve 2 to rotate, thus opening the pipeline.

[0058] Reference Figure 3 and Figure 5 In a preferred embodiment, a support mechanism is disposed on the ball valve 2 to fix the position of the ball valve 2. The support mechanism includes:

[0059] The second rotating rod 14 is fixedly mounted on the ball valve 2; it is used to determine and stabilize the position of the ball valve 2.

[0060] The bearing 15 is fixedly mounted on the valve body 1 and fixedly connected to the second rotating rod 14. It is used to reduce the friction between the second rotating rod 14 and the valve body 1, so that the ball valve 2 can rotate more flexibly.

[0061] Working principle: When ball valve 2 is closed, manually rotating the key 10 drives the double-ended screw 9 to rotate. The double-ended screw 9 drives two moving plates 11 to move closer together. One moving plate 11 moves the first filling column 6, and the other moving plate 11 moves the second filling column 7, so that the first filling column 6 and the second filling column 7 fill the space inside ball valve 2. At this time, the water inside ball valve 2 flows out of the space inside ball valve 2 through the drain groove 19. When ball valve 2 is under pressure, the first filling column 6 and the second filling column 7 distribute a certain amount of pressure, thereby preventing ball valve 2 from deforming. When it is necessary to open the pipeline, rotating the key 10 drives the double-ended screw 9 to rotate. The double-ended screw 9 drives the moving plates 11 to move away from each other, thereby moving the first filling column 6 and the second filling column 7 out of the internal space of ball valve 2. Manually rotating the rotating plate 13 drives the first rotating rod 12 to rotate, and the first rotating plate 13 drives the ball valve 2 to rotate, thus achieving the opening function.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
