Embodiment Construction

[0008] The spool is composed of a spool head 1, a copper inner sleeve 2, and a sealing ring 3. The spool and the valve stem 5 are connected by a movable seal, so that during the movement of the valve stem 3, if it is not coaxial with the PTFE sleeve 4, it can still maintain The valve core is sealed with the PTFE sleeve 4. The PTFE sleeve 4 is installed at the bottom of the melting or mixing tank. The valve body 6 is cast from stainless steel and is a double-layer jacket structure. There will be no solidification in the material, and the discharge port adopts a flange structure, which is convenient for connection. A PTFE guide sleeve 8 is used in the sliding part of the valve stem and the valve body to prevent friction between metals. The seal of the valve stem is sealed with PTFE packing seal 9, the drive of the valve stem is driven by the cylinder 10, the cylinder piston is equipped with a magnetic ring, and the pull rod outside the cylinder is equipped with an intrinsically ...

Abstract

The invention provides a liquid explosive discharging device technology, which can realize automatic safety discharge of liquid explosive as well as manual emergency discharge and flow control in case of emergency power-off. In the invention, a valve body is of a sandwich structure, two ends of the sandwich structure are provided with a water inlet and a water outlet, high-temperature hot water is introduced into the sandwich structure so as to realize heat preservation function and prevent the liquid explosive from being solidified; a valve core is movably and hermetically connected with a valve rod so that reliable sealing property can be still kept in the event that the valve rod and the valve body are not concentric; the valve core and the valve body are sealed by a Teflon sleeve flange so as to ensure sealing reliability; and meanwhile the valve rod and the valve body are sealed by using Teflon packing, and the sliding part between the stainless steel valve rod and the valve body is isolated by a Teflon sleeve, which effectively prevents metal friction during the movement process of the valve rod, avoids sparks and shock and prevents explosion.

Description

Technical field [0001] The invention relates to a liquid explosive automatic feeding device and its structure in the automatic production of explosives, and is especially suitable for automatic safe production of explosives, safe automatic feeding of equipment such as explosive production, projectile body injection technology, and drug injection balls. Background technique [0002] The automatic production of ammunition and explosives is to melt and mix multi-component explosives, inject projectiles, inject balls, and produce mixed explosives. The liquid explosives are characterized by high temperature control requirements, explosives are easy to solidify, flammable, Explosive and highly dangerous. However, ordinary discharge valves, such as ball valves, diaphragm valves, and gate valves, cannot meet the special requirements for liquid explosive discharge. The automatic safe discharging device for liquid explosives of the present invention meets the special requirements for...
