Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that most of the existing stop valves used on ships have large volumes. When opening or closing the valve, it is necessary to apply a large pressure to the valve disc to move the valve disc, so it is more laborious. , it is not easy to open and close the problem, and the proposed new marine stainless steel globe valve

Abstract

The invention discloses a novel marine stainless steel stop valve, and belongs to the technical field of stop valves. The novel marine stainless steel stop valve comprises an upper valve body, a lowervalve body and a valve rod piece, wherein the upper valve body is connected with the lower valve body, the valve rod piece is movably connected to the upper valve body, and a rotating gear is fixedlyconnected to the valve rod piece; a first connecting plate and a second connecting plate are fixedly connected to the lower valve body, and a first gear is rotationally connected to the first connecting plate; the first gear is engaged with a first turntable through a gear; the second connection plate is rotationally connected with a second gear, the second gear is engaged with a second turntablethrough a gear, pulling rods are connected to the first turntable and the second turntable, and the ends, far away from the pulling rods, of the first gear and the second gear are engaged with a first rotating column through gears. The novel marine stainless steel stop valve can provide force in the vertical direction, the operation is simple and saves labor, the valve rod piece can be conveniently driven to move up and down, and a valve clack can be opened and closed.

Description

technical field [0001] The invention relates to the technical field of stop valves, in particular to a novel stainless steel stop valve for ships. Background technique [0002] The globe valve, also known as the gate valve, belongs to the forced sealing valve. The opening and closing part of the globe valve is a plug-shaped disc, the sealing surface is flat or conical, and the disc moves linearly along the center line of the fluid; the movement form of the valve stem , There is also a lifting and rotating rod type. The globe valve is only suitable for full opening and full closing, and adjustment and throttling are not allowed. When the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. [0003] The stainless steel globe valve is a globe valve, which has relatively high requirements on the material of the valve body, and is widely used in chemical industry, shipbuilding, medicine, food machinery and other industries. [0004] A s...
