Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically a disassembly device for quick connection between a roller valve and a pipeline. Background Technology

[0002] In many industrial fields, such as chemical, petroleum, and water treatment, roller valves are widely used in pipeline systems to control fluid media, such as flow regulation and flow direction switching. Roller valves are usually connected to pipelines through specific connection methods to ensure that fluid can be transmitted smoothly and stably between pipelines and valves. Common connection methods include flange connection, threaded connection, and clamp connection. Among them, clamp connection is widely used in many occasions due to its advantages such as convenient installation, ability to withstand certain pressure, and ability to adapt to thermal expansion and contraction of pipelines.

[0003] However, when the fluid in the pipeline flows in a turbulent state, there are a large number of vortices and irregular pulsations inside the fluid. These pulsations generate impact forces that frequently act on the inner wall of the pipeline, causing fluctuations in the pressure on the pipeline. This can easily lead to pipeline vibration, resulting in a decrease in the clamping force of the clamps on the pipeline and affecting the sealing of the pipeline connection. Especially when transporting pressurized fluid media, leakage is likely to occur. This not only wastes resources but may also pollute the surrounding environment. In some special fields such as chemical and petroleum, fluid leakage may even cause safety accidents, endangering the lives and property of personnel. Utility Model Content

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figure 1-4As shown, a disassembly device for quick connection between a roller valve and a pipeline includes an upper clamp 1 and a lower clamp 2. Both the upper clamp 1 and the lower clamp 2 are semi-circular in design, which facilitates the fixing of the roller valve and the pipeline.

[0016] Both sides of the upper clamp 1 are fixedly connected with upper connecting ears 3, and both sides of the lower clamp 2 are fixedly connected with lower connecting ears 4. The upper connecting ears 3 and the lower connecting ears 4 are used together to facilitate the fixing of the upper clamp 1 and the lower clamp 2.

[0017] The inner wall of the upper connecting ear 3 is provided with a fixing mechanism 5, which can connect the upper connecting ear 3 and the lower connecting ear 4 together.

[0018] The fixing mechanism 5 includes a bolt 51 threaded to the inner wall of the upper connecting ear 3. The top of the bolt 51 has a hexagonal structure design, which provides the necessary conditions for subsequent use.

[0019] The surface of the bolt 51 is threaded to the inner wall of the lower connecting ear 4. A nut 52 is provided at the bottom of the lower connecting ear 4. The nut 52 has a hexagonal structure design. A fixing rod 53 is fixedly connected to the bottom of the lower connecting ear 4. There are six fixing rods 53, which are arranged in a circular array with the center point of the nut 52. By setting the six fixing rods 53, the nut 52 can be fixed and the nut 52 can be prevented from rotating accidentally.

[0020] A fixing block 6 is embedded at the bottom of the lower connecting ear 4. The inner wall of the fixing block 6 is threaded to the surface of the bolt 51. The fixing block 6 has a hexagonal structure and is made of rubber. The fixing block 6 is used in conjunction with the nut 52.

[0021] The inner cavity of the upper connecting ear 3 is provided with a compression mechanism 7, which can fix the bolt 51, thereby preventing the bolt 51 from loosening unexpectedly and effectively improving the stability and reliability of the clamp connection.

[0022] The compression mechanism 7 includes a mounting groove 71 formed on the surface of the upper connecting ear 3, and a fixing shell 74 is slidably connected to the inner wall of the mounting groove 71.

[0023] Both the mounting groove 71 and the fixing shell 74 are hexagonal structures, and the inner wall of the fixing shell 74 is slidably connected to the surface of the bolt 51.

[0024] A spring 72 is fixedly connected to the bottom of the mounting groove 71. One end of the spring 72 is fixedly connected to the bottom of the fixed shell 74. A sliding block 73 is slidably connected to the inner wall of the mounting groove 71. One side of the sliding block 73 is fixedly connected to one side of the fixed shell 74. There are six springs 72 and six sliding blocks 73, which are arranged in a circular array with the center point of the fixed shell 74.

[0025] With the cooperation of the sliding block 73 and the mounting groove 71, the fixed shell 74 can be guided when moving, and the fixed shell 74 is prevented from falling out of the inner cavity of the mounting groove 71, thereby making the fixed shell 74 more stable during use.

[0026] The special material fixing block 6 can play a fine-tuning role in the tightening process of bolt 51, so that the staff can align bolt 51 with fixing shell 74 and fix fixing shell 74.

[0027] Working principle: First, place the upper clamp 1 and lower clamp 2 on the surface of the roller valve and the pipe. Then, insert the nut 52 into the inside of the fixing rod 53 and hold it with your hand. The nut 52 does not need to be rotated. Then, use an Allen wrench to tighten the bolt 51. At this time, the Allen wrench will press the fixing shell 74 downward, while driving the sliding block 73 to slide on the inner wall of the mounting groove 71 and compressing the spring 72, pressing the fixing shell 74 into the inner cavity of the mounting groove 71, so as to facilitate the operator to tighten the bolt 51.

[0028] The specially designed fixing block 6 allows the bolt 51 to form a deformation space that allows for continuous rotation. This allows the bolt 51 to be tightened slightly until the hexagonal corners of the bolt 51 and the fixing shell 74 are aligned. Then, the Allen wrench is removed. At this point, the spring force of the spring 72 causes the fixing shell 74 to move upward, locking the bolt 51 into the inner cavity of the fixing shell 74, thus fixing the bolt 51. At the same time, the nut 52 is also fixed under the action of the fixing rod 53. This effectively reduces the problem of bolt 51 loosening caused by factors such as long-term vibration of the pipeline, pressure changes, or temperature fluctuations, ensuring that the pipeline connection can always be in a tight connection state and effectively guaranteeing the pipeline's sealing performance. When it is necessary to loosen the bolt, the Allen wrench is used to press the fixing shell 74 down and onto the surface of the bolt 51, allowing it to be rotated.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
