Embodiment Construction

[0015] Such as figure 1 As shown, the sliding watertight door hydraulic control device of the present invention includes an upper oil cylinder 6, a lower oil cylinder 4 and an oil tank 20, and the upper oil cylinder 6 and the lower oil cylinder 4 are both arranged outside a vertical edge of the sliding watertight door leaf 5, The piston rods of the upper oil cylinder 6 and the lower oil cylinder 4 are parallel, and the outer ends of the two piston rods are arranged in the same direction and are hinged on the sliding watertight door leaf 5 . The rod cavity between the upper oil cylinder 6 and the lower oil cylinder 4, and the rodless cavity between the upper oil cylinder 6 and the lower oil cylinder 4 are all connected by oil pipes. A manual hydraulic pump 2 and an electric hydraulic pump 18 are provided. The oil inlet of the manual hydraulic pump 2 communicates with the oil tank 20 through the first one-way valve 1, and the oil outlet of the manual hydraulic pump 2 communicat...

Abstract

The invention relates to a slide type watertight door hydraulic control device, in particular to a hydraulic control device used for controlling opening/closing of a watertight door in a vessel. The hydraulic control device comprises an upper oil cylinder, a lower oil cylinder and an oil tank, and is characterized in that outer ends of the piston rods of the upper and the lower oil cylinder are equidirectional and hinged to a door hinge of the watertight door in a sliding manner; rod chambers of the upper and the lower oil cylinder, as well as the rodless chambers thereof, are communicated; a manual hydraulic pump and an electric hydraulic pump are arranged between the oil tank and the rod chambers of the upper and the lower oil cylinder; an oil inlet of the manual hydraulic pump is communicated with the oil tank through a first non-return valve, and the oil outlet is communicated with the rod chambers of the upper and the lower oil cylinder through second non-return valves; the oil inlet of the electric hydraulic pump is communicated with the oil tank, and the oil outlet is sequentially communicated with the rod chambers of the upper and the lower oil cylinder through a third one-way valve, a fourth one-way valve and an electromagnetic directional valve; manual reversing valves are arranged between the oil tank and the upper and the lower oil cylinder. The hydraulic control device has the advantages of simple structure, small occupied area, high economical efficiency, and convenience in operation.

Description

technical field [0001] The invention relates to a watertight door control device. Specifically, it is a hydraulic control device used to control the opening or closing of watertight doors on ships, especially for sliding watertight doors. Background technique [0002] At present, on some ships, hydraulic control devices are mostly used to open or close sliding watertight doors. The traditional hydraulic control device is to install an electro-hydraulic pump station and a manual hydraulic pump station on the inside and outside of the door leaf of the watertight door. A watertight door needs two sets of hydraulic control devices, which require more hydraulic components, not only occupying a large space, but also structurally bulky. And because one watertight door needs two sets of hydraulic control devices, not only the economy is not high, but also it is cumbersome to operate. Contents of the invention [0003] The problem to be solved by the present invention is to prov...
