Low pressure anti arch slotted YFA80 blasting disc

Low pressure anti arch slotted YFA80 blasting discIt consists of two or more layers, with one layer being a sealing film and the other layer being a serrated and pressure rod component. The arched convex surface is located on the high-pressure side of the pressure system. When the protected pressure bearing system is overpressure, the pressure rod element is subjected to unstable force, causing the combined sealing membrane to flip over. The sealing membrane is punctured by the serrations of the pressure rod element to release pressure, thereby protecting the pressure bearing equipment.

When the bursting disc and safety valve are connected in parallel, their respective release capacities should not be less than the safety release capacities of the protected pressure bearing devices. The design bursting pressure of the bursting disc should be greater than the set pressure of the safety valve.

When selecting a bursting disc as a safety relief device, factors such as the pressure and pressure difference on both the inlet and outlet sides of the bursting disc safety device should be considered. When the protected pressure equipment has two working conditions of vacuum and pressure, a bursting disc safety device with dual protection of pressure and negative pressure should be selected, or two separate bursting disc safety devices with pressure relief and negative pressure suction protection should be selected.

The pressure rise rate of the bursting test of the bursting disc should be increased to 90% of the small bursting pressure of the test device during the bursting test, and the holding pressure should not be less than 5 seconds. Then, the pressure should be steadily and continuously increased, and the small reading of the pressure gauge should be accurately read during the pressure rise, and the pressure rise rate per second should not be less than 0.1% of the bursting pressure until the bursting disc bursts. This process should not exceed 120 seconds.

Transportation and storage of explosive discs: (1) Explosive disc products should be packaged and inspected to be qualified before transportation. During transportation and handling, collision, impact, moisture and pollution should be avoided; (2) Explosive disc products should be stored in their original packaging box (box) with the front facing up, kept dry, and protected from environmental corrosion. The storage room should be kept clean and ventilated.

The certificate accompanying the explosive disc from the factory: (1) The manufacturing unit shall provide the user with complete instructions and quality certification documents regarding the assembly, installation, use, and maintenance of the explosive disc safety device. (2) Each batch of bursting disc products should have at least the following documents: product quality certificate, product qualification certificate, and product installation and use instructions.

The main types of products are:

1. The anti arch slotted blasting disc YF is used in conjunction with the clamp YJ.

2. Welding type bursting disc YFJ is a device that welds the bursting disc with a metal pressure ring or clamp as a whole, ensuring sealing, easy installation, and convenient use.
