Principle of Bidirectional Flow Rotary Joint

The bidirectional flow rotary joint is a mechanical equipment commonly used for transporting liquids, gases, and other media. It has excellent sealing and reliable corrosion resistance, and is an essential tool in modern industrial production. The following will provide a detailed explanation of its principle.

1、 What is a bidirectional flow rotary joint

The bidirectional flow rotary joint, also known as the "Swivel Joint" in English, refers to a rotating connection composed of two hydraulic pipes. The joint parts on both sides of the rotary joint can remain unchanged, while the rotating part in the middle can rotate freely. This type of joint is suitable for high-speed rotating equipment, such as the connection of various rotary filter plates, drums, etc. It can enable hydraulic fluid to flow in both directions along the connection of two pipelines, thereby achieving transmission and control of the connection.

2、 Principle of bidirectional flow rotary joint

The rotation principle of the bidirectional flow rotary joint is based on the principle of mechanical transmission. It includes a rotating ring with a built-in rotation axis and two fixed connection ends. The rotating ring has two channels inside, which can achieve flow communication between two media. The sealing performance of the joint is ensured by sealing rings and gaskets, and this sealing method combines barrel sealing and O-ring sealing.

3、 Structure and types of bidirectional flow rotary joints

The structure of a bidirectional flow rotary joint is divided into six parts: the rotary joint body, sealing ring, sealing gasket, stop ring, transmission ring, and fixed connection end. According to different application scenarios and medium properties, there are various classification methods for bidirectional flow rotary joints, such as port size, pressure level, rotation angle, material, etc.

4、 Scope of application of bidirectional flow rotary joint

The bidirectional flow rotary joint is suitable for various industries and fields, such as petroleum, chemical, metallurgical, power, light industry, textile, papermaking, cement, shipbuilding and other industrial fields. It can also be used in sewage treatment systems, water conservancy irrigation systems, fire protection systems, oilfield drilling and other fields.

In short, bidirectional flow rotary joints play a huge role in modern industrial production processes, and the rationality of their principles and structural design is the key to ensuring their normal operation and use.
