Core technology innovation
PTC/PTCR composite temperature control module embedded
Embedding PTC (Positive Temperature Coefficient Material) or PTCR (Positive Temperature Coefficient Thermistor) functional layers into the brass substrate enables the adapter to have temperature self-sensing capability.
The temperature response threshold can be customized (60℃~120℃). When the system temperature exceeds the set value, the resistance rises sharply, automatically limiting heat transfer or triggering external protection mechanisms (such as cutting off power, closing valves).
Plug In Design
Using quick snap or push-pull interfaces, installation or disassembly can be completed without complex tools, significantly reducing maintenance time.
Compatible with multiple pipeline standards such as NPT, BSP, and Metric threads, with strong compatibility.
Special features of structural design
(1) Double-sealed structure
Brass body seal: Precision-machined threads or slots ensure mechanical sealing.
Dynamic temperature-sensitive sealing ring: When PTC material triggers high-temperature protection, the sealing ring expands due to heat, further enhancing the sealing effect and preventing leakage.
(2) Thermal electrical isolation design
Brass and PTC/PTCR layers are isolated by an insulating coating to prevent direct current transmission to the pipeline system, ensuring safety (especially suitable for electric heating or charged medium scenarios).
Functional advantages
Intelligent overheat protection:
Real time monitoring of connection point temperature to prevent seal failure or pipeline deformation caused by local overheating (such as steam systems, high-temperature oil circuits).
Linked with external control systems, it can remotely alarm or automatically adjust flow rate.
Energy efficiency optimization:
In a constant temperature system, energy waste is reduced through the self regulating properties of PTC materials (such as underfloor heating water dividers and solar hot water circulation).
Anti vibration and anti fatigue:
The rigid combination of brass and the elastic cushioning of composite materials are suitable for high-frequency vibration environments such as automobiles and aviation.
Typical application scenarios
Industrial automation: Rapid connection and overheat protection of high-temperature hydraulic systems.
New energy vehicles: Temperature sensitive interfaces for battery cooling pipelines to prevent thermal runaway.
Smart Home: A temperature control adapter for instant water heaters to enhance safety and energy efficiency.
Medical equipment: Quick replacement joints for sterilization steam pipelines to avoid the risk of high temperature burns.
Summary
The Plug In Adapter of PTC and PTCR Composite series deeply integrates the mechanical properties of traditional brass fittings with the active temperature control capability of PTC materials through material composite and structural intelligence, solving the connection and safety problems in high temperature and high reliability scenarios. Its fast installation, self-protection, and long lifespan make it an ideal choice for upgrading fluid systems in fields such as Industry 4.0, new energy, and smart homes.
