Description

Technical Field

[0001] This utility model belongs to the field of pipeline valve technology, specifically a compact pipeline valve structure. Background Technology

[0002] Pipeline valves are control components installed in various fluid transport pipelines. Their core function is to control the flow, flow, or pressure of fluid in the pipeline by adjusting the position or state of the internal valve core. They typically consist of a valve body, valve core, valve stem, drive device, and sealing components. They can stably control the transport state of fluid in the pipeline according to actual usage requirements and are an indispensable key component in fluid transport systems. They are widely used in municipal engineering, petrochemicals, water treatment, energy, machinery manufacturing, and many other fields.

[0003] In existing technologies, the inlet and outlet pipes of pipeline valves are integrally formed with the valve body or rigidly connected by bolts. Their lengths are fixed after the valve is manufactured, and cannot be flexibly adjusted according to the space requirements of the actual pipeline installation scenario. For example, in some narrow equipment interiors or densely packed pipeline areas, when the spacing between pipes does not match the fixed length of the valve's inlet and outlet pipes, additional pipe joints, short pipes, and other connecting parts are required to compensate for the length difference. This not only increases the installation complexity of the pipeline system, but also increases fluid resistance due to the addition of connecting parts, affecting the conveying efficiency.

[0024] Specifically, by Figure 2-3The regulating mechanism 2 includes two support plates 201 symmetrically fixed to the outside of the valve body 1. Two guide rods 203 are symmetrically fixedly connected between the two support plates 201. Two guide plates 207 are symmetrically and movably sleeved between the two guide rods 203. Connecting columns 2010 are fixedly connected to the opposite sides of the two guide plates 207. An outer ring 206 is fixedly connected to one end of each connecting column 2010. Corrugated hoses 204 are fixedly connected to both sides of the valve body 1. Two corrugated hoses 204 are respectively installed at the inlet and outlet of the valve body 1. Water inlet pipes 205 are fixedly connected to the opposite ends of the two corrugated hoses 204. Two outer rings 206 are fixedly sleeved on the outside of the two water inlet pipes 205. Because the corrugated hoses 201... 4. It has telescopicity, which facilitates the horizontal movement of the water pipe 205. The outer side of the valve body 1 is provided with a mounting frame 202. The mounting frame 202 is fixedly sleeved on the outer side of two guide rods 203. The inner side of the mounting frame 202 is rotatably connected to a rotating shaft 2011. The end of the rotating shaft 2011 away from the mounting frame 202 is fixedly connected to a disc 208. The side of the disc 208 away from the rotating shaft 2011 is fixedly connected to a handle 2012. The disc 208 is located between the two guide rods 203 and between the two guide plates 207. The side of the disc 208 away from the rotating shaft 2011 is symmetrically rotatably connected to two movable rods 209. The ends of the two movable rods 209 away from the disc 208 are rotatably connected to the outer side of the two guide plates 207 respectively.

[0025] In use, firstly, the disc 208 is rotated by the handle 2012, which drives the rotating shaft 2011 to rotate. The two movable rods 209 drive the two guide plates 207 to slide along the two guide rods 203. Then, the two connecting columns 2010 drive the two outer rings 206 to move. At the same time, the two water pipes 205 move horizontally, so as to adjust the distance between the two water pipes 205.
