Abstract

The invention discloses an anti-collision valve for a fore peak. The anti-collision valve for the fore peak comprises a screw type stop valve and an execution driving structure, wherein the screw type stop valve comprises a valve rod, a bonnet, a valve disc and a valve body; the bonnet has a shaft sleeve type hollow structure with an upper end flange and a lower end flange; the valve rod upwards penetrates in the bonnet; the upper end of the valve rod is in threaded connection with the upper end flange of the bonnet; the execution driving structure is arranged on the bonnet and comprises a spline, a driving shaft sleeve and a sliding block; the spline is fixedly connected to the middle of the upper end of the driving shaft sleeve, so that a shaft sleeve structure with an opening in the lower end is formed; the sliding block is in threaded connection with a rod end, which extends out of the upper end flange of the bonnet, of the valve rod; the driving shaft sleeve covers the upper end surface of the upper end flange of the bonnet; and the sliding block is covered in the driving shaft sleeve, is in clearance fit with a straight groove which is vertically formed in the inner wall of the driving shaft sleeve, and can vertically slide along the straight groove vertically formed in the inner wall of the driving shaft sleeve. The anti-collision valve for the fore peak is characterized by also comprising a stroke control mechanism. The anti-collision valve can be remotely controlled on a console in a centralized manner, and is opened or closed rapidly; the working efficiency is high; and the safety performance is also high.

Description

technical field [0001] The invention relates to a valve, in particular to a fore peak tank anti-collision valve. Background technique [0002] The forepeak anti-collision valve generally adopts a screw-type globe valve, which is installed in the anti-collision bulkhead in the forepeak tank of the ship, and is submerged in seawater for the control of the forepeak tank ballast pipeline. The opening and closing of the forepeak anti-collision valve in the prior art is a manual structure, and it is troublesome and time-consuming to open or close the valve by one person, and it is inconvenient to use. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a fore peak tank anti-collision valve which can quickly open or close the valve and is easy to use. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The forepeak anti-collision valve includes a screw-type stop valve, and...
