Background

The relay initiation refers to an initiation method in which an explosive with higher sensitivity is initiated first by a detonator or a detonating cord, and then an explosive with lower sensitivity is initiated again by the detonator or the detonating cord. The technique is suitable for low-sensitivity explosives which cannot be directly detonated by a detonator, such as common oil explosives, explosive charges and the like. The high sensitivity explosive is made into an initiating explosive package, a detonator or an detonating cord is arranged in the initiating explosive package, the initiating explosive package can be expanded, and then the insensitive mine explosive can be excited to explode.

The relay detonator is a civil blasting equipment for detonating insensitive explosives. The relay detonator generally adopts a cylindrical hollow paper shell or a plastic shell in the traditional production process, and the hollow paper shell is sleeved on a special mould during production, then materials are injected, and the mould is withdrawn after cooling and forming.

The emergency valve is used for rapidly closing or opening the valve when an emergency situation occurs in the process of pouring the relay primer, so that accidents and environmental hazards are avoided. In the process of pouring the relay detonator, the conventional emergency valve adopts a cylinder holding type emergency switch, and large friction exists in the switching process, so that the safety coefficient is low, and the reliability is poor.
