Wireless Valve Control System Reduces Wiring Costs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing valve opening and closing systems require extensive electric wiring for forced closing operations from a center control room, leading to increased construction costs due to long-distance wiring.
Innovation Solution
A valve opening and closing system that includes a site/center switching manual valve, an opening/closing switching electric driving valve, a center wireless transmitter, and a site side valve control device with a receiving unit, converting unit, and interlock unit, allowing for wireless operation instructions to be transmitted and executed without on-site electric wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electric wiring is installed from the center control room to the electric driving valve for forced closing operation, then forced closing operation can be performed from the center control side, but construction cost increases due to long-distance wiring work
Solution Approach 1:
The patent replaces the mechanical/electrical wiring system with a wireless communication system. The center wireless transmitter transmits operation instructions wirelessly to the site side valve control device, eliminating the need for physical electric wiring between the center control room and the electric driving valve, thus reducing construction costs while maintaining forced closing operation capability
Solution Approach 2:
The patent introduces a wireless communication system as an intermediary between the center control room and the site side valve control device. The center wireless transmitter and site side receiver act as mediators to transmit control signals without requiring direct electrical connection, solving the contradiction between operational control and construction cost
2Extent of automation
If electric wiring is installed for remote control, then center control room can control manual valve operations, but wiring complexity and installation difficulty increase
Solution Approach 1:
The patent replaces complex electrical wiring infrastructure with wireless communication technology. The center wireless transmitter communicates operation instructions wirelessly to the site side valve control device, eliminating the need for extensive electrical infrastructure while maintaining remote control automation capability
3Reliability
If extensive electric wiring is installed on site, then forced closing operation can be executed, but installation time and maintenance complexity increase
Solution Approach 1:
The patent substitutes wireless communication for electrical wiring, eliminating physical connection points that require maintenance. The wireless transmission system has no moving parts or connection interfaces on site, significantly reducing maintenance complexity while maintaining reliable forced closing operation capability

AI summary
A valve opening and closing system includes: a site/center switching manual valve; a manual valve for opening and closing operation; an opening/closing switching electric driving valve that opens and closes a manual valve and that nullifies the manual valve for opening and closing operation; a center wireless transmitter that accepts and transmits an operation instruction including an opening and closing operation instruction and a forced closing operation instruction; and a site wireless transmitter, and a contact signal converter, the site side valve control device transmits both of the opening and closing operation instruction and the forced closing operation instruction to the contact signal converter when the site/center switching manual valve is switched to the center control side, and interrupts the opening and closing operation instruction and transmits the forced closing operation instruction to the contact signal converter when the site/center switching manual valve is switched to on site.
