Design and Deveopment of a low cost Safety Valve for the commercially used Gas heaters in Pakistan
Project Area of Specialization Mechanical EngineeringProject SummaryIn Pakistan, every year a number of causalities are caused by the gas leakage through the heaters due to load-shedding during the winter season. Locally manufactured gas heaters do not follow any safety standards to automatically shut the gas valve in case of sudden variation in pressure or gas supply from the main supply as this problem is growing with the serious ratio in Pakistan. This results in a room filled with unburned gas thus causing suffocation to humans as well as fire hazards blunders. The aim of this project is to design and develop a low-cost safety gas valve that can be incorporated into local heaters to shut the gas supply in the heater in case of any uneven or fluctuating gas supply.
Project Objectives- To decrease the number of causalities caused by gas leakage
- Low Cost effective
- Contribution to the market
- Mathematical Calculation of the shut-off pressure for the valve
- Designing and modeling the valve
- Designing of the electronics components
- Assembly of the Valve
- Testing and validation of the design
This technology will be used in commercial heaters to prevent gas leakage during load shedding thus avoiding any possible incident and human life losses especially in under-developed countries like Pakistan.
Technical Details of Final Deliverable- Design and installation details for the sensor
- CAD Model of the sensor
- Final working sensor tested and validated on some local gas heaters
