Angle type duplex ball valve for nuclear submarine and using method thereof

Abstract

The invention relates to the technical field of valves, in particular to an angle type duplex ball valve for a nuclear submarine and a using method thereof. The angle type duplex ball valve comprisesa valve body, a pipeline is arranged inside the valve body, the pipeline is connected with a first ball body and a second ball body, sealing rings are arranged at the joint between the first ball bodyand the pipeline and the joint between the second ball body and the pipeline correspondingly, a first valve deck and a second valve deck are arranged at the upper end of the valve body, a first bearing penetrating through the first valve deck is arranged at the upper end of the first ball body, a hydraulic oil cylinder is arranged at the upper end of the first bearing and connected with the firstvalve deck through screws, a second bearing penetrating through the second valve deck is fixedly arranged at the upper end of the second ball body, a worm reduction gearbox is fixedly arranged at theupper end of the second bearing and connected with the second valve deck through screws, a worm is arranged on the worm reduction gearbox, and a rotating wheel is fixedly arranged at the outer end ofthe worm. According to the angle type duplex ball valve for the nuclear submarine and the using method thereof, a top-mounted structure is adopted, and two pure mechanical valve balls are adopted forcontrol, so that the opening and closing performance is safe and reliable, and the size of the valve is more compact.

Description

technical field [0001] The invention relates to an angle-type double-connection ball valve and a use method thereof, in particular to an angle-type double-connection ball valve for nuclear submarines and a use method thereof, belonging to the technical field of valves. Background technique [0002] A nuclear submarine is a type of submarine, referring to a submarine designed with a nuclear reactor as a power source. Due to the production and operation costs of this kind of submarine, plus the size and weight of related equipment, only military submarines use this power source. The closing part is driven by the valve stem and rotates around the axis of the ball valve. It can also be used to regulate and control the fluid. Among them, there is a strong shear force between the ball core of the hard-sealed ball valve and the metal seat of the surfacing carbide. Cutting force, especially suitable for media containing tiny solid particles, etc., and the double ball valve can not ...

AI Technical Summary

Problems solved by technology

[0003] The existing ball valves used for nuclear submarines have a large structure, occupy a large space, and mostly use advanced electrical control technology. The risk of failure in the harsh seabed environment will lead to the failure of device control, resulting in serious disasters. In nuclear submarines, due to space constraints, a control valve with reliable opening and closing and compact size is urgently needed
