ESP Check Valve Adapter for Reversible Vent Port Retrofitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ESP assemblies face challenges in flexibility and efficiency due to the non-interchangeability of different types of check valves, requiring redesign and re-manufacturing of parts for different flow control needs, which increases costs and reduces maintenance ease.
Innovation Solution
A check valve adapter that allows a cartridge-style check valve to be used in an NPT screw-style vent port, enabling interchangeable operation in either direction without altering the port, thereby facilitating quick and cost-effective retrofitting and improved flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different types of check valves are used in ESP assemblies, then flow control performance is improved, but device complexity increases due to non-interchangeability requiring multiple port designs
Solution Approach 1:
The adapter assembly enables a single NPT screw-style vent port to accommodate multiple types of check valves (cartridge-style and ball-style), making the port universal and eliminating the need for different port designs for different valve types. This resolves the contradiction by maintaining adaptability while reducing device complexity.
Solution Approach 2:
The adapter assembly acts as an intermediary component that bridges between the fixed NPT screw-style vent port and different check valve types. By introducing this mediator, the system achieves versatility in valve selection without increasing port design complexity.
2Ease of repair
If cartridge-style check valves are installed in NPT screw-style vent ports, then ease of maintenance is improved, but device complexity increases without the adapter
Solution Approach 1:
The adapter assembly serves as a mediator that simplifies the installation of cartridge-style check valves in NPT screw-style vent ports. Without the adapter, direct installation would require complex modifications. The adapter makes maintenance easier while adding minimal complexity compared to the alternative of custom-fitted ports.
Solution Approach 2:
The adapter assembly divides the installation system into separate functional components: the NPT screw-style vent port, the adapter assembly, and the cartridge-style check valve. This segmentation allows each component to be optimized independently and facilitates easier maintenance and replacement.
3Reliability
If custom ports are manufactured for different check valve types, then reliability is improved through proper fit, but manufacturing costs increase
Solution Approach 1:
Instead of manufacturing custom ports for each check valve type, the invention uses a universal NPT screw-style vent port combined with an adapter assembly. This approach maintains reliable connection while significantly reducing manufacturing costs by eliminating the need for multiple custom port designs and their associated tooling and production complexity.
4Adaptability or versatility
If multiple vent port designs are used for different check valves, then adaptability is improved, but ease of operation deteriorates due to assembly variations
Solution Approach 1:
The NPT screw-style vent port with adapter assembly creates a universal interface that works with different check valve types. This eliminates the need for operators to learn and execute different assembly procedures for different port types, thereby improving ease of operation while maintaining adaptability.

AI summary
One or more check valves may be used in a motor protector for an ESP assembly. Disclosed embodiments relate to a check valve adapter configured to provide additional versatility regarding such check valves. The adapter may have a first end portion, configured for removable attachment to an NPT screw-style vent port, and a second end portion configured to receive a cartridge-style check valve. The first end portion of the adapter is in fluid communication with the second end portion, and the second end portion can be configured to receive the cartridge-style check valve in either orientation, thereby allowing fluid flow through the adapter in either direction merely based on the orientation of the cartridge-style check valve. Systems for using an adapter with a cartridge-style check valve in an ESP assembly, as well as methods of controlling fluid flow in a motor protector using such an adapter, are also disclosed.
