Product catalog summary

Sphere Release Mechanisms Overview

Sphere release mechanisms are essential components in various industrial applications, particularly in systems involving the deployment of spheres. These mechanisms can include:

Mechanical fingers
Flaps
Valves

Mechanical Fingers

Mechanical fingers are the most commonly used mechanism for sphere release. However, they become impractical for spheres exceeding 20 inches in diameter. For larger spheres, which can weigh up to 500 kilograms, flaps are preferred due to their ability to handle the high loads imposed by such large spheres.

System Configuration

Typically, two fingers or flaps are installed in launchers to allow multiple spheres to be loaded into the barrel. This setup enables the sequential launching of single spheres at a predetermined rate. In systems with declined receivers, a single finger is often used to prevent the sphere from rolling towards the operator when the closure door is opened.

Applications

Both fingers and flaps are applicable in traps designed for conventional and intelligent pigs, highlighting their versatility in different operational contexts.

SPHERE RELEASE FINGERS Sphere Release Mechanisms may involve any of the following: • Mechanical fingers • Flaps • Valves Mechanical Fingers are the most popular but are not really practical for use with traps in which the spheres exceed 20”ns. Above this diameter it is more practical to use flaps which are designed to absorb the high loads that a large sphere, weighing up to 500 kilos, can impose. Fig 1. Sphere Release Fingers It is normal to fit two fingers or flaps to launchers so that multiple spheres can be loaded into the barrel after which single spheres can then be launched, at a pre-determined rate, by sequencing the operation of the fingers or flaps. For declined receivers, it is common to fit a single finger to prevent the sphere from rolling onto the operator as the closure door is opened. Fingers and flaps can also be used in traps intended for conventional and intelligent
