QHF Type Gas Tank Pressure Relief Valve

In the industrial sector, air storage tanks are crucial energy equipment used to store compressed air for various production processes. However, the internal air pressure of these tanks constantly fluctuates, and if not promptly controlled and regulated, it may lead to safety issues. To address this problem, we have specifically introduced the QHF-type air storage tank pressure relief valve, providing safer and more reliable protection for your production.

Working Principle:

When the pressure relief valve activates, the protective cover prevents the piston from flying out and causing injury, ensuring safety protection. This pressure relief valve is installed in the air compressor system, directly facing the airflow direction at the outlet pipeline of the air receiver. When the air compressor system operates normally, the system pressure is ≤0.785 MPa (8 kgf/cm²), under which the pressure relief valve functions properly. If the air receiver ignites due to carbon buildup or if gas accumulates excessively for any reason, causing a sudden rise in temperature and pressure within the system, when the pressure reaches 1.04±0.059 MPa (10.6±0.6 kgf/cm²), the pull rod immediately breaks, and the pressure relief valve activates. This rapidly releases the high-temperature, high-pressure gas from the air receiver and pipelines, thereby mitigating shock waves and preventing major accidents.

Product Advantages:

(1)High protection level, ensuring that during pressure relief, the piston does not burst through the upper flange, causing safety accidents, flying out, or generating intense noise.

(2)Effectively eliminates the impact of piston resistance on the breaking tension of the piston pull rod.

(3)The piston's thickness has a unique relationship with gas discharge guidance. The proportional relationship between the piston pull rod's extension characteristics and the cylinder stroke is scientific and reasonable. The tolerance limit for piston displacement and the method for reducing operational resistance are handled scientifically.

(4)The cylinder stroke channel is smooth, ensuring sensitive and reliable operation. The pull rod has strong high-temperature resistance, corrosion resistance, and anti-aging capabilities.

(5)Effectively addresses the issue of installation position of the pressure relief valve and the pipeline loss along the gas path.

(6)Effectively resolves the impact of temperature and corrosive gases inside the pressure relief valve cylinder on the breaking tension of the piston pull rod.

The QHF-type air storage tank pressure relief valve provides a comprehensive protection solution for your production processes, ensuring that your operations are safer, more reliable, and more efficient. We firmly believe that with this safety protection device, your production processes will achieve unprecedented optimization and enhancement.
