Introducing the Intelligent Anti-leakage Protection Valve for Heating System

I. Project Background and Market Demand

There are approximately 220 million households in northern regions that rely on centralized heating. Each year, the direct economic losses caused by water leakage in the heating system exceed 2 billion yuan. The causes of leakage are diverse, including aging pipes, improper installation, and unauthorized water drainage, which not only affect household life but also result in the loss of resources and benefits for the heating company.

Currently, most leakage detection products are based on flow detection and have problems such as low sensitivity (requiring a leakage volume of over 30% to be detected), high cost, and prone to false alarms, which cannot effectively prevent small-flow leakage.

II. Core Principle of the Product: Pressure Change Detection Technology

This product breaks through the limitations of traditional flow detection and utilizes the incompressibility of water to monitor the pressure changes within the system in real time, enabling rapid and accurate identification of various leaks (including burst pipes, seepage, dripping, etc.).

Detection logic is simple:

- The system forms a sealed pressure range after the flow is shut off;

- Minor leaks cause detectable pressure drops;

- If the pressure drop exceeds the set threshold (such as 0.7 kilograms), it is determined as a leak, and the valve is automatically closed and an alarm is triggered.

III. Product Advantages and Innovation Points

IV. Key Structural Innovation: Capsule-type Diaphragm Valve

It uses a circular bottom capsule-type diaphragm, with uniform force and sensitive response;

The auxiliary water flow control chamber pressure is controlled to drive the main valve to open and close with minimal power consumption;

It breaks through the traditional limit of a pressure difference of ≥ 0.2 kilograms for membrane valve operation, and can operate stably at a micro-pressure difference of 0.01 kilograms.

V. Experimental Verification and Results

- Continuous multi-month field tests showed no impact on heating effects, and temperature fluctuations were controllable;

- Leakage detection responses were timely, the operation was smooth without noise;

- It is compatible with actual heating conditions (pressure difference of 0.2–0.6 kilograms), and the system has good compatibility.

VI. Application Scenarios

Suitable for household radiator systems, floor heating systems, and入户 pipelines of heating companies， effectively preventing：

1. Pipeline sudden burst

2. Slow leakage at joints and valves

3. Unauthorized water drainage by users
