Problems solved by technology

Since the anti-corrosion rod is installed inside the screw plug, the plug must be opened regularly to check the corrosion of the anti-corrosion rod. Otherwise, when the anti-corrosion rod is corroded, if the anti-corrosion rod is not replaced in time, the equipment will corrode and affect the use of the equipment.

Embodiment 1

[0017] A marine anti-corrosion screw plug, comprising a screw plug 1 and an anti-corrosion rod 2, the screw plug 1 has an internal thread hole, the screw plug 1 is threadedly connected with the anti-corrosion rod 2, the top of the screw plug 1 is provided with a mounting hole, and screwed into the mounting hole Screw 3, the screw 3 goes deep into the anti-corrosion rod 2, the depth of the screw 3 protruding into the anti-corrosion rod 2 can be set according to the degree of damage of the anti-corrosion rod 2, and a gasket is installed at the connection between the screw plug 1 and the corrosion-resistant rod 2 4; In this way, when the seawater overflows from the installation hole, it means that the anti-corrosion rod 2 needs to be replaced in time.

Embodiment 2

[0019] A marine anti-corrosion screw plug, comprising a screw plug 1 and an anti-corrosion rod 2, the screw plug 1 has an internal thread hole, the screw plug 1 is threadedly connected with the anti-corrosion rod 2, the top of the screw plug 1 is provided with a mounting hole, and screwed into the mounting hole Check the screw plug 5, the anti-corrosion rod 2 has a longitudinal leakage hole 6, the installation hole is connected with the threaded hole, unscrew the inspection screw plug 5 to check the seawater in the leakage hole 6, if seawater seeps in, it means that the anti-corrosion rod 2 needs to be replaced in time; Gasket 4 is installed at the joint between plug 5 and screw plug 1, and gasket 4 is installed at the joint between screw plug 1 and anti-corrosion rod 2.

Embodiment 3

[0021] A marine anti-corrosion screw plug, comprising a screw plug 1 and an anti-corrosion rod 2, the screw plug 1 has an internal thread hole, the screw plug 1 is threadedly connected with the anti-corrosion rod 2, the anti-corrosion rod 2 is provided with a longitudinal leakage hole 6, the screw plug 1 There is a mounting hole on the top, and the inspection mirror 7 is installed in the installation hole; the installation hole is connected with the threaded hole, and there are three steps from top to bottom, narrow at the top and wide at the bottom, the first step is the inspection port, and the inspection mirror is installed in the second step 7. Gaskets 8 are installed on the upper and lower sides of the inspection mirror 7, and the compression ring 9 is installed in the third step. The compression ring 9 is located above the anti-corrosion rod 2, and the gasket 4 is installed at the connection between the anti-corrosion rod 2 and the screw plug 1; Mirror 7 directly observes...

Abstract

An anti-corrosion screw plug for ships, including a screw plug and an anti-corrosion rod. Holes, the fasteners are installed in the mounting holes, and the fasteners are detachable. The present invention provides two solutions, one is to open a hole on the screw plug, the anti-corrosion rod has a longitudinal leakage hole, the screw plug opening is connected to the threaded hole, and the inspection screw plug is installed in the screw plug opening, and the opening depth of the leakage hole is determined according to the needs The situation of the replacement is determined, open and check the screw plug regularly to check whether there is seawater infiltration in the leakage hole, if there is seawater infiltration, it means that the anti-corrosion rod needs to be replaced to prevent the service life of the equipment from being affected; Install the inspection mirror, the hole of the screw plug is connected to the threaded hole, through the inspection mirror, the leakage hole of the anti-corrosion rod can be observed at any time, and the anti-corrosion rod can be replaced as needed to avoid affecting the use of equipment.

Description

technical field [0001] The invention relates to an anti-corrosion screw plug, in particular to a marine anti-corrosion screw plug. Background technique [0002] The traditional anti-corrosion screw plug includes a screw plug and an anti-corrosion rod. The screw plug has an internal thread, one end of the anti-corrosion rod has an external thread, the external thread of the anti-corrosion rod is connected to the internal thread of the plug, and then the anti-corrosion plug is connected to the equipment , to prevent equipment from being corroded by seawater. Since the anti-corrosion rod is installed inside the screw plug, the plug must be opened regularly to check the corrosion of the anti-corrosion rod. Otherwise, when the anti-corrosion rod is corroded, if the anti-corrosion rod is not replaced in time, the equipment will corrode and affect the use of the equipment. . Contents of the invention [0003] In order to overcome the above-mentioned technical problems, the pres...
