Aviation clamps are mainly used in key parts such as aircraft hydraulic systems, and their structural design and material selection have been strictly considered to ensure reliability and safety under extreme conditions such as high vibration, high temperature difference and large deformation. The following is a detailed introduction to the aviation clamp structure:
I. Main types
There are mainly several types of aviation clamps:
Threaded flexible connection clamp: composed of 2 tube sleeves, 1 sealing ring, 1 screw sleeve and 1 nut. After pipe A and pipe B are connected to the tube sleeve, install two sealing rings in the annular groove of the tube sleeve, and press the screw sleeve to the outer edge of the sealing ring through the nut. The sealing ring is a rubber material with a certain amount of compression, which not only ensures sealing and reliability, but also has the compensation ability of axial clearance (36mm) and radial Angle (0°3°).
Quick release clamp: mainly composed of a flange (or concave joint, convex joint) and a clamp with a clamp (including a clamp, hoop, sleeve, bolt, washer, nut). The integrated thin sleeve and split quick release clamp replace the screw sleeve and nut in the threaded flexible connection structure, with the ability to compensate the axial clearance (36mm) and radial Angle (03°), and allow 0.5° radial deflection at the connection site after installation, which can meet the needs of modern aircraft.
P-type clamp: composed of a ring metal bracket with a rubber liner, easy to install, only a bolt is required to fix the upper and lower parts on the bracket. It has the advantages of strong clamping force, small size, flexible installation and low price of a single piece, but it can only clamp a single pipe and has a short service life.
Saddle-type clamp: The saddle-type metal bracket is combined with a rubber gasket. Bolts must be installed on both sides of the saddle-type metal sheet. It has the advantages of convenient installation and maintenance, high reliability and low unit price.
Second, structural characteristics
High-strength materials: Aviation clamps are usually made of high-strength, corrosion-resistant materials, such as stainless steel, aluminum alloy, etc., to ensure stability and durability in extreme environments.
Precision manufacturing: The manufacturing process of the aviation clamp requires precision machining and heat treatment to ensure that its dimensional accuracy and surface quality meet the design requirements.
Sealing performance: The threaded flexible connection clamp is sealed by the seal ring, while the quick release clamp ensures the sealing performance by the tight fit of the clamp and the band. These designs can effectively prevent media leakage and ensure the safety of the system.
Compensation ability: The aviation clamp has a certain axial clearance and radial Angle compensation ability, which can adapt to the small deformation of the pipeline caused by temperature changes, vibration and other factors, so as to maintain the stability and reliability of the connection.
Easy installation and maintenance: The design of aviation clamps usually takes into account the ease of installation and maintenance, such as the use of quick discharge structure, standardized size, etc., to reduce the installation difficulty and cost.
In summary, the structural design of aviation clamp fully considers its application needs in key parts such as aircraft hydraulic system, with high strength, precision manufacturing, good sealing performance, compensation ability and easy installation and maintenance. These characteristics make the aviation clamp have a wide application prospect in the aviation field.
