Description

Technical Field

[0001] The utility model relates to the technical field of pipeline joints, in particular to a high-pressure resistant hydraulic pipeline safety joint. Background Art

[0002] Fluid delivery systems are widely used in the delivery of liquids or gases. For example, gasoline and natural gas are more common. Fluid delivery systems include fuel or natural gas pipelines that can deliver thousands of kilometers of fuel or gas. Pipelines that deliver fluids can be made of different materials, including steel, iron, copper, aluminum and plastic. The safety of thousands of kilometers of fluid delivery pipelines is not only related to the material of the pipeline, but also the installation of the pipeline is crucial; especially the connection between straight-through pipelines and fluid diversion points; the connection of fluid delivery pipelines, therefore, requires high-pressure hydraulic pipeline safety joints.

[0003] The existing high-pressure hydraulic pipeline safety joints are difficult to fix circular water inlet pipes of different specifications within a certain range when in use, resulting in the water inlet pipes and the joints falling off, affecting the normal operation of the device, and the outflowing liquid or gas poses a safety hazard; it is difficult to replace a single device during use, and the installation process is relatively cumbersome, resulting in high maintenance costs and low maintenance efficiency. Utility Model Content

[0004] The utility model aims to provide a high-pressure resistant hydraulic pipeline safety joint to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-pressure hydraulic pipeline safety joint comprises a rubber gasket, wherein the internal sliding connection of the rubber gasket is provided with a connecting component, both sides of the connecting component are through-connected with mounting components, a first limiting hole is provided at the top of the mounting component, and the internal sliding connection of the first limiting hole is provided with the limiting component, and through the arrangement of the mounting component, the limiting component and the connecting component, the limiting block can be pressed during use to compress the limiting spring in the mounting tube, and then the mounting tube is inserted into the fixing column by using the mounting ring to fit tightly against the first rubber ring, while the limiting block passes through the first limiting hole on the mounting tube and the second limiting hole on the fixing column to fix the position between the mounting tube and the fixing column, and then the first connecting tube with the rubber gasket is rotated to connect with the second connecting tube, and then the above operation is repeated to install the pipeline on the other side, so as to facilitate installation. When installing, local parts can also be replaced individually, which achieves the effect of improving work efficiency and reducing maintenance costs. One end of the installation component is movably connected with a first rubber ring, and the surface of the installation component is slidably connected with a fixing column, one side of the inner wall of the fixing column is movably connected with a second rubber ring, and the other side of the top of the fixing column is provided with a threaded hole, and the internal thread of the threaded hole is connected with a fixing component. Through the setting of the fixing component, when in use, the water inlet pipe can be placed in the fixing column and close to the second rubber ring in the fixing column, and then the fixing bolt on the fixing column is rotated, so that the fixing bolt moves downward and drives the fixing plate to be close to the inside of the water inlet pipe to fix the position between the water inlet pipe and the fixing column, thereby achieving the effect of fixing circular water inlet pipes of different specifications within a certain range, and avoiding the situation where the water inlet pipe is not fixed firmly.

[0007] The connecting assembly includes a first connecting tube, one side of the surface of the first connecting tube is movably connected to the inside of the rubber gasket, and the second connecting tube is threadedly connected to one side of the surface of the first connecting tube close to the rubber gasket. Through the setting of the connecting assembly, the first connecting tube with the rubber gasket can be rotated to connect with the second connecting tube during use, so that the first connecting tube and the second connecting tube are in a through state and cooperate with the rubber gasket to prevent water leakage, thereby achieving the effect of easy disassembly and good sealing, and avoiding leakage between the first connecting tube and the second connecting tube.

[0008] The mounting assembly comprises a mounting ring, the back side of the mounting ring is through-connected to one end of the second connecting pipe, and the middle part of the surface of the mounting ring is through-connected to the mounting pipe.

[0009] The limiting assembly comprises a limiting block, the bottom end of the surface of the limiting block is slidably connected to a first limiting hole opened at the top end of the mounting tube, and the bottom end of the limiting block is fixedly connected to a limiting spring.

[0010] Through the setting of the installation component and the limit component, the limit block can be pressed during use to compress the limit spring in the installation tube, and then the installation tube is inserted into the fixed column using the installation ring to fit the first rubber ring. At the same time, the limit block passes through the first limit hole on the installation tube and the second limit hole on the fixed column, which is convenient for installation and disassembly, thereby achieving the effect of improving work efficiency and avoiding the situation where cumbersome installation and disassembly work affects work efficiency.

[0011] The fixing assembly includes a fixing bolt, the bottom end of the fixing bolt surface is threadedly connected to a threaded hole opened on the other side of the top of the fixing column, and the bottom end of the fixing bolt is rotatably connected to a fixing plate. Through the setting of the fixing assembly, the fixing bolt on the fixing column can be rotated during use, so that when the fixing bolt moves downward, it drives the fixing plate to tightly adhere to the inside of the water inlet pipe to fix the position between the water inlet pipe and the fixing column, thereby achieving the effect of fixing the water inlet pipe.

[0012] A second limiting hole is formed on one side of the top end of the fixing column, and the interior of the second limiting hole is slidably connected to the top end of the surface of the limiting block.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The high-pressure hydraulic pipeline safety joint can press the limit block to compress the limit spring in the mounting tube when in use through the arrangement of the mounting assembly, the limit assembly and the connecting assembly. Then, the mounting tube is inserted into the fixing column by using the mounting ring and is close to the first rubber ring. At the same time, the limit block passes through the first limit hole on the mounting tube and the second limit hole on the fixing column to fix the position between the mounting tube and the fixing column. Then, the first connecting tube with the rubber gasket is rotated to connect with the second connecting tube. Then, the above operation is repeated to install the pipeline on the other side. While facilitating installation, local parts can also be replaced individually, thereby achieving the effect of improving work efficiency and reducing maintenance costs.

[0015] 2. The high-pressure hydraulic pipe safety joint, through the setting of the fixing component, can place the water inlet pipe in the fixing column close to the second rubber ring in the fixing column when in use, and then rotate the fixing bolt on the fixing column, so that the fixing bolt moves downward and drives the fixing plate to be close to the inside of the water inlet pipe to fix the position between the water inlet pipe and the fixing column, thereby achieving the effect of fixing circular water inlet pipes of different specifications within a certain range.
