Abstract

The utility model discloses a seal ring for a through-wall galvanized pipe. The section of the seal ring is U-shaped, the curvature radius R of the outer convex surface of the seal ring is equal to 6mm, the curvature radius R of the inner concave surface of the seal ring is equal to 11mm, and the inner concave surface is provided with plug-in bolts. Because the section of the seal ring is of a U shape, when the seal ring is extruded, the end of the seal ring can compress inwards, and good sealing is achieved; because of low hardness of the seal ring, the seal ring can be easily crammed and compressed into small holes in irregular shapes and with different hole diameters, and good fixing and sealing effects are achieved; in addition, by means of the arrangement of the plug-in bolts, broken seal rings can be rapidly removed when the seal rings are replaced.

Description

Used for galvanized tube seal ring through walls
Technical field
The utility model relates to a kind of used for galvanized tube seal ring through walls.
Background technique
When the galvanized pipe of gas pipeline passes wall, floor, need be in wall, flooring boring, for convenience of construction, general aperture of holing is larger, therefore, between galvanized pipe and hole, can leave larger space, and it exists following not enough:
1. larger space easily causes galvanized pipe to rock, and may exert an influence to pipe joint sealing for a long time;
2. in hole, galvanized pipe can wear away coating because rocking, and affects corrosion resistance;
Once 3. gas leakage occurs a certain floor, combustion gas can flow into other floor by space, jeopardizes other floor resident's the security of the lives and property;
4. in the meeting of the sewage on flooring ostium, accumulate for a long time and can corrode galvanized pipe, also easily cause gas leakage.
Therefore, how to avoid the appearance of above-mentioned condition, become the problem of needing solution in combustion gas galvanized pipe process of deployment badly.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of used for galvanized tube seal ring through walls, causes danger situation to occur to avoid leaving space between galvanized pipe and body of wall.
For achieving the above object, the technical solution of the utility model is as follows:
A used for galvanized tube seal ring, the cross section of described seal ring is U-shaped, and the radius of curvature of its outer convex surface is R=6mm, and the radius of curvature of its inner concave is R=11mm, and on described inner concave, is provided with plug bolt.
Preferably, the material of described seal ring is vulcanized rubber or nitrile butadiene rubber.
Preferably, described plug bolt has 4, is separately positioned on foursquare four summits of inscribe of described seal ring.
By technique scheme, the used for galvanized tube seal ring through walls that the utility model provides, in use, first seal ring be enclosed within on galvanized pipe and fill in together in hole, then seal ring is inwardly compressed, just galvanized pipe can be fixed in body of wall hole, its tool has the following advantages:
1. the section due to seal ring is U-shaped, and when seal ring is squeezed, its end can inwardly be compressed, thereby forms excellent sealing;
2. because the hardness of seal ring is lower, therefore, for out-of-shape, the inconsistent aperture of hole, can be easy to fill in, compress, thereby play fixing, seal action preferably;
3. owing to being provided with plug bolt, when needs are changed seal ring, only need to can conveniently remove damaged seal ring by plug bolt, and without by instrument, damaged seal ring destructiveness being taken out.
In addition, adopt the utility model after hole sealing, can prevent from, in effluent stream hand-hole, having prevented corrosion in water galvanized pipe, also can prevent that combustion gas is mobile at floor gap by space.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.
Fig. 1 is the disclosed used for galvanized tube seal ring cross section structure schematic diagram through walls of embodiment;
The structural representation of Fig. 2 when to be seal ring shown in Fig. 1 install for galvanized pipe through walls.
Numeral in figure:
11. seal ring 12. plug bolt 21. fuel tube 22. built-in pipe 23. substrates
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
According to Fig. 1, the used for galvanized tube seal ring 11 through walls that the utility model provides, its cross section is U-shaped, and the radius of curvature of its outer convex surface is R=6mm, and the radius of curvature of its inner concave is R=11mm; On inner concave, be provided with 4 plug bolts 12, be separately positioned on foursquare four summits of inscribe of seal ring, seal ring material is vulcanized rubber or nitrile butadiene rubber.
With reference to figure 2, while using the utility model that galvanized pipe through walls is installed, first built-in pipe 22 is packed in the hole of substrate 23, then seal ring 11 is enclosed within zinc-plated fuel tube 21 and fills in together in built-in pipe 22, seal ring 11 is between fuel tube 21 and built-in pipe 22, then seal ring 11 is inwardly compressed, seal ring 11 distortion in U-shaped cross section, thereby fuel tube 21 is fixed on closely in the built-in pipe 22 of substrate 23, and because the hardness of seal ring 11 own is lower, therefore, for out-of-shape, the inconsistent aperture of hole can be filled in easily, compress, thereby play fixing preferably, seal action, owing to being provided with plug bolt 12, when needs are changed seal ring, only need to can conveniently remove damaged seal ring by plug bolt 12, and without by instrument, damaged seal ring destructiveness being taken out.
To the multiple modification of above-described embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.
