Abstract
The utility model discloses an anti-corrosion screw plug with high reliability. The anti-corrosion screw plug with high reliability is provided with an anode bar and a screw plug, wherein an internal threaded hole is formed in one end of the anode bar; a screw plug is assembled into the internal threaded hole; the screw plug is made of a copper bar or stainless steel materials. The anti-corrosion screw plug with high reliability is simple in structure, and is convenient to install and replace; the screw plug is wrapped in the anode bar, is corroded slowly without falling off so as to guarantee the anticorrosion issue of connected elements.
Description
Technical field
The utility model relates to the aseptic technic field in machinofacture, is especially applied to the anticorrosion plug screw of the high reliability of the cathode protection method of the sacrificial anode of the industry interchanger such as petrochemical complex, boats and ships, metallurgy, naval vessels, locomotive and pipeline.
Background technology
The material that the cathode protection method of all kinds of sacrificial anodes that adopt is now used is the alloy materials such as magnesium, aluminium, zinc.The fixing method of anode material has two kinds of modes, a kind of fixed form is that positive plate is fixed by bolts on protected product, adopt after fixing positive plate work for some time of this structure, as need are changed positive plate, the parts that are associated must be taken apart and could be changed, this structure is changed positive plate difficulty, and loses time; It is bar-shaped that another kind of fixed form is that anode manufactures; one end car of anode bar is made screw thread and is connected with plug screw; both are referred to as the anticorrosion plug screw of anticorrosion plug screw (referring to Fig. 1) and with being threaded, are fixed on protected product; this structure can guarantee to install and change and be very easy to; but this kind of fixing means is the outside that plug screw is wrapped in anode bar; plug screw very easily corrodes, and causes the separation of anode bar and plug screw, after anode bar comes off, does not have etch-proof effect.
Summary of the invention
The purpose of this utility model is improved above shortcoming exactly, provides simple in structure, and plug screw is wrapped in slow corrosion in anode bar and does not come off, and guarantees the anticorrosion plug screw of the high reliability of the Anticorrosion Problems of connected piece.
Concrete scheme of the present utility model is: the anticorrosion plug screw of high reliability, there is anode bar and plug screw, and it is characterized in that: described anode bar one end has internal thread hole, is fitted with plug screw in internal thread hole.
The anticorrosion plug screw of described high reliability, is characterized in that: described plug screw copper rod or stainless material are made.
The utility model is simple in structure, and it is convenient to install and change, and plug screw is wrapped in slow corrosion in anode bar and does not come off, and guarantees the Anticorrosion Problems of connected piece.
Accompanying drawing explanation
Fig. 1 is existing anticorrosion plug screw schematic diagram;
Fig. 2 is the utility model structural representation.
In figure, 1-anode bar, 2-plug screw, 3-internal thread hole.
Embodiment
Referring to Fig. 1-2, the anticorrosion plug screw of the utility model high reliability, has anode bar 1 and plug screw 2, and described anode bar 1 one end has internal thread hole 3, is fitted with plug screw 2 in internal thread hole 3; Described plug screw 2 use copper rods or stainless material are made.
Claims (2)
1. the anticorrosion plug screw of high reliability, has anode bar and plug screw, it is characterized in that: described anode bar one end has internal thread hole, is fitted with plug screw in internal thread hole.
2. the anticorrosion plug screw of high reliability according to claim 1, is characterized in that: described plug screw copper rod or stainless material are made.
