Bolt fixed bursting disc (compressed air storage tank pressure relief device)

Bolt fixed bursting disc (compressed air storage tank pressure relief device)It is an integrated overpressure relief safety device designed specifically for small low/medium pressure systems. With the characteristics of "compact structure, easy installation, and reliable sealing", it is widely used in industrial scenarios with limited space and small pressure scales. Its core function is to quickly rupture and release pressure when the system is overpressure, protect equipment from overpressure damage, and adapt to diverse media and working conditions.

1、 Core adaptation scenarios
Bolt fixed bursting disc (compressed air storage tank pressure relief device)Accurately matching small pressure equipment, typical applications include:
In the general industrial field, hydraulic accumulators, high-pressure cleaning machines, and small compressed air storage tanks are used to solve the protection needs of such equipment with small space and smooth pressure fluctuations;
In the field of refrigeration and air conditioning, the condenser of the air conditioning system, the high-pressure side of the refrigeration unit, and the sealing and release of refrigerant media (such as R32, R410A) are adapted;
Special equipment field: laboratory small reaction vessels, portable high-pressure gas cylinders, pressure tanks for food processing (optional food grade materials), meeting special requirements such as high precision and hygiene grade;
In the fields of people's livelihood and commercial use: gas wall mounted boiler stabilizing tank, small water heater pressure chamber, ensuring the pressure safety of civilian equipment.

2、 Structure composition and working principle
1. Structural design (integrated)
Blasting diaphragm: a core pressure bearing component with a thickness of 0.1-1.5mm, made of materials selected according to the medium (such as 316L stainless steel resistant to acid and alkali, pure nickel resistant to strong corrosion, Inconel resistant to high temperature), and formed by precision stamping to ensure accurate rupture pressure;
Bolt clamp: includes 4-8 sets of standard bolt holes, with built-in sealing grooves and positioning rings, which can fix the diaphragm to prevent displacement, and can be directly connected to the equipment flange through bolts without the need for additional clamping components;
Sealing element: Suitable media include nitrile rubber (ordinary medium), fluororubber (corrosive medium) or food grade silicone rubber (sanitary scenario), embedded in the sealing groove of the clamp to ensure no leakage under normal working conditions.
2. Work logic (precise response to overpressure)
Under normal operating conditions, the bolt clamp tightly presses the blasting diaphragm onto the equipment flange interface, and the sealing element fills the gap to achieve ANSI Class VI sealing (no medium leakage); When the system pressure rises to the preset burst value, the diaphragm is subjected to tensile stress exceeding the material strength limit, quickly rupturing along the preset weak area, forming a release channel that is consistent with the interface size. The overpressure medium is instantly discharged, and the system pressure drops back to the safe range; Due to the rupture of the membrane, it cannot be repaired and the device needs to be replaced as a whole to restore its protective function.
