1Bolt type bursting disc | Pre assembled explosion-proof pressure relief deviceIntroduction

■Combination bolt type explosive discIt is an integrated overpressure relief safety device designed specifically for small low/medium pressure systems,

■With the characteristics of compact structure, convenient installation, and reliable sealing, it is widely used in industrial scenarios with limited space and small pressure scales,

■The core function is to quickly rupture and release pressure in case of system overpressure, protect equipment from overpressure damage, and adapt to diverse media and working conditions.

■Combination bolt type explosive discAccurately matching small pressure equipment, typical applications include:
■General industrial sector:Hydraulic accumulator, high-pressure cleaning machine, small compressed air storage tank, to solve the protection needs of such equipment with "small space and smooth pressure fluctuations";
■In the field of refrigeration and air conditioning:Sealing and release of refrigerant media (such as R32, R410A) on the high-pressure side of the condenser and refrigeration unit of the air conditioning system;
■Special equipment field:Small laboratory reactors, portable high-pressure gas cylinders, and pressure tanks for food processing (optional food grade materials) meet special requirements such as high precision and hygiene grade;
■Livelihood and Commercial Fields:Gas wall mounted boiler stabilizing tank and small water heater pressure chamber ensure the pressure safety of civilian equipment.

IIBolt type bursting disc | Pre assembled explosion-proof pressure relief deviceStructural Design (Integrated Integration)

■Blasting diaphragmCore pressure bearing components, 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, and Inconel alloy resistant to high temperature),

■By precision stamping and forming, ensure accurate rupture pressure;
■Bolt clamp:Contains 4-8 sets of standard bolt holes, with built-in sealing grooves and positioning rings, which can fix the diaphragm to prevent displacement,

■It can also be directly connected to the equipment flange through bolts without the need for additional clamping components;
■Sealing element:Select nitrile rubber (ordinary medium), fluororubber (corrosive medium) or food grade silicone rubber (sanitary environment) as the suitable medium,

■Insert the clamp sealing groove to ensure no leakage under normal operating conditions.
3、 Work logic (precise response to overpressure)
■Under normal operating conditions, the bolt clamp tightly presses the rupture disc onto the equipment flange interface, and the seal 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 and rapidly ruptures along the preset weak area,

■Form a release channel that is consistent with the interface size, instantly discharge the overpressure medium, 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.
