Because the JGD flexible rubber elbow has the advantages of shock absorption, noise reduction and good sealing performance in the pipeline system, it is widely used in pipeline connections in petroleum, chemical, electric power, pharmaceutical, food and other fields. However, in practical application, due to the quality and improper installation of rubber elbows, air leakage, water leakage and other phenomena often occur, which brings great hidden dangers to production and safety. Therefore, this article will introduce the structure, performance, installation and use of JGD type flexible rubber elbow in detail, in order to provide readers with a comprehensive understanding of the product and the correct way to use it.
1. The structure of JGD flexible rubber elbow.
The JGD type flexible rubber elbow is composed of a ball, a flange and a rubber material. The ball is the hollow part of the rubber elbow, which has good pressure resistance and corner function. Flanges are the key components that hold and connect pipes, and are usually made of carbon steel or stainless steel. Rubber material is the key factor that determines the performance of rubber elbows, common natural rubber, styrene-butadiene rubber, neoprene, etc.
Second, the performance characteristics of JGD flexible rubber elbow.
1.Shock absorption: Due to the elasticity of the rubber material, the JGD flexible rubber elbow can effectively absorb the vibration and noise in the pipeline, reduce the impact of the fluid on the pipeline, and improve the stability of the pipeline system.
2.Sealing performance: Good sealing performance is the key to ensure the normal operation of the pipeline system. JGD flexible rubber elbow adopts high-quality rubber materials and advanced production technology, which ensures that it has good sealing performance and can effectively prevent the leakage of gas and liquid.
3.Corrosion resistance: JGD flexible rubber elbow is made of rubber material with good corrosion resistance, which can resist the erosion of various chemical media and prolong the service life.
4.Easy installation: Due to the large radius of curvature and low weight of the JGD flexible rubber elbow, the installation is easy and fast, which can reduce the installation time and cost.
3. Installation and use of JGD flexible rubber elbow.
1.Preparation before installation: Before installation, check whether the model and specification of the rubber elbow meet the design requirements, and check whether the ball and flange are damaged or cracked. At the same time, the environment of the installation site should be ensured to be clean and avoid the impact of debris and dust on the installation quality.
2.Installation sequence: In the installation process, the principle of installing large caliber first and small caliber should be followed, and installed one by one according to the requirements of the design drawings. When connecting two adjacent rubber elbows, it should be ensured that their axes coincide to avoid the instability of the pipeline system due to installation errors.
3.Flange connection: Flange connection is the key link to ensure the stability of rubber elbows. When connecting, make sure that the flange surface is flat and clean, and the bolt holes are aligned. At the same time, the bolts should be tightened according to the specified torque to avoid the occurrence of air leakage or water leakage caused by insufficient tightening force.
4.Installation precautions: During the installation process, care should be taken to avoid sharp objects scratching the surface of the sphere, so as not to affect the sealing performance and service life. At the same time, rubber elbows should be avoided from being exposed to harsh environments such as high temperatures, strong ultraviolet rays or chemicals, so as not to accelerate their aging or corrosion.
5.Use and maintenance: During use, the sealing performance and appearance of the rubber elbow should be checked regularly, and if there is air leakage, water leakage or damage, it should be repaired or replaced in time. At the same time, the pipeline system should be cleaned regularly to remove the impurities and dirt accumulated in the pipeline to maintain the normal operation and service life of the pipeline system.
In a word, as an important pipe connection element, the performance and quality of JGD flexible rubber elbow directly affect the stability and safety of the entire pipeline system. Therefore, the correct selection and use of JGD flexible rubber elbow is of great significance to ensure production and personal safety.
