Abstract

Abstract The illustrated connecting device is adapted to provide a flexible connection between a pipeline and a pump, compressor, engine, vessel, reactor, or another pipeline, or any other machine, device or equipment to protect the equipment against stresses and strains due to the fluid pressure in the pipeline, and also due to thermal expansion and contraction in the pipeline. The connecting device also protects the equipment against other forces and vibrations which might otherwise be transmitted to the equipment by the pipeline. The transmission of vibrations from the equipment to the pipeline is also minimized. In addition, the connecting device reduces the transmission of noise in both directions between the equipment and the pipeline. The connecting device may comprise a casing having first and second diametrically opposite portions and a third portion extending generally perpendicular to the first and second portions. A pipeline coupling section extends into the first portion of the casing and is rigidly connected thereto. A conduit is disposed within the casing and is provided with first and second diametrically opposite conduit sections and a third conduit section extending generally perpendicular to the first and second sections. A first flexible bellows is connected between the first section of the conduit and the pipeline coupling section. A second flexible bellows is connected between the second conduit section and a blind pipe section connected to the second portion of the casing. The equipment is adapted to be connected to an equipment-connecting section which is rigidly connected to the third section of the conduit. A third flexible bellows is connected between the equipment-connecting section and the third portion of the casing. The third bellows provide flexibility between the equipment-connecting section and the casing, while preventing the transmission of forces to the equipment due to the fluid pressure in the pipeline.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 185 words
A flexible connecting device for use between a pipeline and a machine or equipment, comprising a casing having first and second diametrically opposite portions and a third portion extending transversely to said first and second portions, a pipeline connecting pipe section extending into said first portion of said casing, means forming a substantially rigid sealed joint between said pipeline connecting pipe and said first portion of said casing, a blind pipe section connected with another substantially rigid sealed joint to said second portion of said casing and disposed therein, conduit means disposed within said casing and having first and second diametrically opposite conduit sections and a third conduit section extending transversely to said first and second conduit sections, a first flexible bellows connected between said pipeline connecting pipe section and said first conduit section, a second flexible bellows connected between said blind pipe section and said second conduit section, an equipment-connecting section secured to said third conduit section with another substantially rigid sealed joint, and a third flexible bellows connected at opposite ends to said equipment-connecting section and to said third portion of said casing.
Claim 2
Dependent Claim 185 words
A flexible connecting device for use between a pipeline and a machine or equipment, comprising a casing having first and second diametrically opposite portions and a third portion extending transversely to said first and second portions, a pipeline connecting pipe section extending into said first portion of said casing, means forming a substantially rigid sealed joint between said pipeline connecting pipe and said first portion of said casing, a blind pipe section connected with another substantially rigid sealed joint to said second portion of said casing and disposed therein, conduit means disposed within said casing and having first and second diametrically opposite conduit sections and a third conduit section extending transversely to said first and second conduit sections, a first flexible bellows connected between said pipeline connecting pipe section and said first conduit section, a second flexible bellows connected between said blind pipe section and said second conduit section, an equipment-connecting section secured to said third conduit section with another substantially rigid sealed joint, and a third flexible bellows connected at opposite ends to said equipment-connecting section and to said third portion of said casing.
Claim 3
Dependent Claim 37 words
A device according to claim 1, in which said third portion of said casing is substantially perpendicular to said first and second portions, said third conduit section being substantially perpendicular to said first and second conduit sections.
Claim 4
Dependent Claim 18 words
A device according to claim 1, in which said first, second and third bellows are made of metal.
Claim 5
Dependent Claim 20 words
A device according to claim 3, in which said casing, conduit, connecting sections and blind section are made of metal.
Claim 6
Dependent Claim 19 words
A device according to claim 1, including anchor means connected to said casing to secure said casing against movement.
Claim 7
Dependent Claim 46 words
A device according to claim 1, in which said casing has a space therein between said casing and said conduit, said device including a pressure sensor connected to said space for detecting any changes in the pressure in said sPace as an indication of possible leakage.
Claim 8
Dependent Claim 50 words
A device according to claim 6, including a fluid pressure source for pressurizing said space whereby any decrease in the pressure within said space will be indicative of leakage from said casing, any increase in the pressure in said space being indicative of leakage between said conduit and said casing.
Claim 9
Dependent Claim 21 words
A device according to claim 1, including a vibration damping material disposed in said casing between said caing and said conduit.
Claim 10
Dependent Claim 56 words
A device according to claim 1, in which said casing, conduit and bellows are made of metal, said third portion of said casing being substantially perpendicular to said first and second portions, said third conduit section being disposed within said third portion of said casing and being substantially perpendicular to said first and second conduit sections.
Claim 11
Dependent Claim 47 words
A device according to claim 9, in which said casing has a space therein between said casing and said conduit, said device including a pressure sensor for detecting any change in the pressure in said space as an indication of leakage into or out of said space.
