Description

Technical Field

[0001] The invention relates to the technical field of civil detonating equipment, and more particularly to an emergency valve for pouring a relay detonator. Background Art

[0002] Relay detonation refers to a method of detonating a more sensitive explosive first with a detonator or detonating cord, which then detonates a less sensitive explosive. This technology is suitable for low-sensitivity explosives that cannot be directly detonated with a detonator, such as ordinary oil-pressed explosives and shaped explosives. A detonator or detonating cord is placed in a detonating bag made of a more sensitive explosive to expand its detonation energy and then trigger the explosion of the less sensitive mining explosive.

[0003] Relay detonators are civilian blasting equipment used to detonate insensitive explosives. In the traditional production process, relay detonators generally use cylindrical hollow paper shells or plastic shells. During production, the hollow paper shells need to be put on a special mold, and then the material is injected, and the mold is removed after cooling and forming.

[0004] The emergency valve refers to the valve that will be quickly closed or opened when an emergency occurs during the pouring process of the relay detonator to avoid accidents and environmental damage. In the pouring process of the relay detonator, the emergency valve used in the past used a cylinder-supported emergency switch, which had great friction during the opening and closing process, so the safety factor was low and the reliability was poor.

[0005] Therefore, how to provide an emergency valve for pouring relay detonators with high safety factor and strong reliability is a problem that technical personnel in this field need to solve urgently. Summary of the invention

[0006] In view of this, the present invention provides an emergency valve for pouring a relay detonator to solve the above-mentioned problems raised in the above-mentioned background technology part, thereby realizing pouring emergency treatment with a higher safety factor.
