These media cover all aspects of daily life and industrial production. Through the connection of pipeline force transmission joints, the stable transmission of various substances in the pipeline system is guaranteed.

In practical applications, force transmission joints are of great significance for the transportation of different media. For example, when conveying drinking water, its sealing performance ensures the safety of water quality and prevents water pollution; when conveying energy materials such as crude oil and fuel oil, its reliable connection and sealing performance ensure the efficient transmission of energy.

Industry application Electric power, metallurgy: Force transmission joints are often used in this field because of their metal product characteristics, high tensile and compressive strength, excellent sealing performance, and convenient loading and unloading. In the power industry, force transfer joints are used to connect various pipelines in power plants to ensure the normal operation of power equipment. For example, in the pipeline connection of large generator sets, force transfer joints can withstand huge axial forces and pressures to ensure the stability and safety of pipelines.

In the metallurgical industry, force transfer joints also play an important role. It can connect various metal smelting equipment and pipelines, withstand harsh environments such as high temperature and high pressure, and ensure the smooth progress of the production process. For example, in the steelmaking workshop of a steel plant, force transfer joints are used to connect steelmaking furnaces and pipelines to ensure the stability of the steelmaking process.

2. Water supply and drainage and sewage treatment: force transfer joints are mainly used to connect water pumps with valves and pipelines. In the water supply and drainage system, it plays a multi-directional displacement role in the operation of the pipeline, relieves the thrust of the blind plate, and protects the pipeline. When the water pump is started, the force transfer joint can transfer the axial force generated by the water pump to the pipeline system to avoid damage to the pipeline due to uneven force.

In sewage treatment plants, force transfer joints also play an important role. It can connect sewage pipelines with treatment equipment to ensure the smooth discharge and treatment of sewage. For example, in the connection between the aeration tank, sedimentation tank and other equipment in the sewage treatment plant and the pipeline, the force transmission joint can effectively compensate for the expansion and displacement of the pipeline and ensure the normal operation of the equipment.

The force transmission joint is widely used and important in various industries. It provides a guarantee for the stable operation of the pipeline system and promotes the development of various industries.

3. Advantages of force transmission joints

Easy installation The installation of the force transmission joint is simple and convenient, and it can make the installation process easier for the installation of the valve. In actual installation, when the pipeline is connected to the valve, it can withstand the axial tension of the pipeline, making the installation process more stable and reliable. For example, in some large pipeline systems, the installation of valves often requires precise positioning and fixing. The existence of force transmission joints can effectively reduce the difficulties in the installation process and ensure that the valves are firmly installed. This not only improves the installation efficiency, but also provides convenience for subsequent pipeline maintenance and overhaul.

Reliable performance

Material and sealing products are made of metal casting or welding, which makes them have good strength and stability. The loose sleeve part uses a trapezoidal rubber sealing ring. The principle of elastic deformation of rubber compression is used. Under the action of the gland and the bolt, the sealing ring is forced to perform static sealing between the outer wall of the expansion tube of the joint body. This sealing method can effectively prevent medium leakage and ensure the normal operation of the pipeline system.

For example, when conveying some pressurized media, the sealing ring can fit tightly on the outer wall of the expansion tube to ensure that the medium will not leak from the joint.

Material selection Metal and sealing ring are strictly selected according to the performance and user requirements. The metal part is coated with high-strength anti-corrosion paint on the outside, which not only enhances the corrosion resistance of the metal, but also extends the service life of the pipeline. The connecting bolts are made of high-strength carbon steel or stainless steel to ensure the strength and reliability of the joint.

In practical applications, the selection of these materials enables the force transmission joint to adapt to various complex working environments. For example, in the transportation of some highly corrosive media, the joint can maintain good performance.

Powerful force transmission joints can effectively compensate and relieve the thrust of pipelines and blind plates. During the operation of the pipeline system, when the pipeline is subjected to pressure or thrust, the force transmission joint can absorb these forces through its own expansion and displacement, thereby protecting the pipeline and blind plate.At the same time, it facilitates the installation, maintenance and replacement of water pumps and valves. For example, during the installation of water pumps and valves, the force transmission joint can be adjusted according to the actual situation to make the installation smoother. When maintaining and replacing water pumps and valves, the force transmission joint can also be easily disassembled and installed to improve work efficiency. This makes the pipeline force transmission joint an indispensable and important component in the pipeline installation and transportation industry.

4. Precautions for use

Installation position The force transmission joint should be installed at the outlet of the water pump and the corner of the pipeline. When the water pump is started, the thrust of the blind plate is transmitted to various parts of the pump and pipeline through the force transmission bolt to avoid the thrust being concentrated on the pipeline or the near end of the pump. This is because the pipeline force transmission joint can better play its role in compensating and alleviating the thrust of the pipeline in these positions, ensuring the stable operation of the pipeline system.

For example, at the outlet of the water pump, the force transfer joint can effectively transfer the axial force generated by the water pump to the pipeline to prevent the pipeline from being damaged due to concentrated force; at the corner of the pipeline, the force transfer joint can withstand the axial tension of the pipeline, so that the pipeline remains stable at the bend.

Quality Assurance It is recommended to purchase force transfer joints from professional and formal manufacturers to ensure product quality. This is because the products produced by professional and formal manufacturers usually have high quality standards and good performance. For example, the metal materials and sealing rings used in their products can ensure the strength and sealing performance of the products.

The metal exterior is coated with high-strength anti-corrosion paint, and the connecting bolts are made of high-strength carbon steel or stainless steel, which makes the product have good corrosion resistance and reliability. Purchasing from professional and formal manufacturers can also guarantee the after-sales service of the product, and problems with the product can be solved in time, so as to achieve a longer service life and avoid deformation or damage caused by poor product quality.
