Used in many places in productionCombination washer, This ensures the sealing effect of the pipeline, so it is often repaired and replaced. Today, the editor will briefly introduce the use of the combination gasket and the matters needing attention in the use process.

Brief introduction of 1. combination washer

The combination gasket is a sealing ring in which a rubber ring and a metal ring are integrally bonded together. It is used to seal screw and flange connections and is composed of a metal ring and a rubber seal. There are two sizes of metric system and imperial system, which can be divided into type A and type B according to the structure. Once damaged, it often leaves a great danger at the sealing site, and leakage may occur even once. Choose the correct specifications of the combination gasket, the metal ring of the combination gasket is generally not easy to damage in production, and the rubber ring will be checked and replaced regularly. The editor reminds everyone to choose the correct specifications of the rubber ring. Don't have a fluke to choose a slightly smaller or larger rubber ring.

The metal gasket of the combined gasket can ensure the stable connection and safe fixing of the components. The thickness of the retaining ring limits the compression of the elastomer seal, eliminating the phenomenon of exceeding the limited torque in the joint, thereby ensuring the reliability of the sealing system. It is generally used together with the ferrule type pipe joint, in order to prevent oil, fuel, water, medicine and other leakage, the metal ring for rust-proof treatment, rubber ring generally use oil-resistant nitrile rubber or fluorine rubber. The structure is simple and the price is low, so it has been widely used in the machinery manufacturing industry.

In the process of replacing the combination gasket, the following items need to be paid special attention: The sealing ring cannot be installed forcibly. Some seals are placed in the grooves. It must be installed at this time. Be careful when operating and install slowly. Can not be indiscriminately, the action of large forced installation. Otherwise, the seal will be damaged and cannot play a proper sealing role. Secondly, the installation should be balanced and symmetrical, and the seals should be placed in parallel on the effective sealing surface. After installation, further observation is required. If there is a leak, it should be reinstalled in time to avoid leakage during the production process. This leads to production interruptions. Do not damage the rubber ring sealing surface or sealing line. The sealing performance of the flat seal depends on the upper and lower sides. If damage occurs, leakage may occur. The rubber ring is made of soft and flexible rubber, fiber and other special materials, so pay attention to scratches, abrasions, collisions, etc. during handling, installation and maintenance.

Well, the above content is Xiaobian to introduce aboutCombination washerIt is believed that this will help reduce the occurrence of leakage accidents in future production and maintenance.
