Choke Seat and Stroke Layout for Large Debris in Small Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional choke systems are inefficient, often built larger than necessary, leading to increased manufacturing and operating costs, as they fail to effectively accommodate larger debris while maintaining acceptable fluid dynamics.
Innovation Solution
The choke system is designed with reduced dimensions for the intake and increased dimensions for the seat and stroke length, allowing larger debris to pass through while using smaller conduits and maintaining fluid dynamics, by optimizing critical dimensions such as the minimum distance between the gate and input channel exit, and the seat channel diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional choke systems are built larger to accommodate larger debris, then debris passage capability is improved, but manufacturing costs and operating costs increase
Solution Approach 1:
The patent applies local quality by differentiating the dimensions of different parts of the choke system. Specifically, the seat and stroke length are made larger to accommodate debris passage, while the intake dimensions are reduced to minimize cost. This selective sizing allows the system to pass large debris through the optimized seat area without requiring the entire system to be oversized, thereby resolving the contradiction between debris passage capability and manufacturing cost.
2Adaptability or versatility
If conventional choke systems are built larger to accommodate larger debris, then debris passage capability is improved, but operating costs increase
Solution Approach 1:
The patent resolves this contradiction by optimizing only the critical dimensions (seat and stroke length) that directly impact debris passage, rather than scaling up the entire system. This localized optimization reduces the overall size of the system, which in turn reduces operating costs associated with larger equipment while maintaining the capability to pass large debris through the specifically designed seat area.
3Ease of manufacture
If intake dimensions are reduced to lower costs, then manufacturing cost decreases, but debris passage capability worsens
Solution Approach 1:
The patent applies local quality by concentrating the debris passage functionality in the seat and stroke length dimensions, while using smaller intake dimensions. This creates a specialized flow path through the seat that accommodates large debris without requiring the entire system, including the intake, to be oversized. The result is cost-effective manufacturing with maintained debris passage capability.
4Adaptability or versatility
If seat and stroke length are increased to pass larger debris, then debris passage capability is improved, but system complexity increases
Solution Approach 1:
The patent resolves this contradiction by making targeted increases only to the seat and stroke length dimensions that are critical for debris passage, rather than increasing all system dimensions. This localized approach improves debris passage capability while minimizing the overall complexity increase, as only specific components are modified rather than the entire system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables the passage of larger debris without requiring larger lines, reducing costs and maintaining acceptable fluid dynamics, achieving economic advantages and improved operational efficiency.
Implementation Method 1
the lower border of the gate being configured to engage the seat when the gate is fully closed to block fluid flow through the seat channel
Implementation Method 2
the choke system is to convey fluid through the body channel and the seat channel when the gate is open and fluid is pressurized in the input channel

AI summary
Embodiments include a choke system that passes enlarged debris despite having a relatively small diameter for an input port of the choke system. Embodiments also include systems to prevent dislodging of a choke seat when backpressure is supplied to the choke system. Embodiments also include sealing systems to prevent fluid leaks around the choke seat of the choke system.
