Abstract
The utility model relates to a seal structure of a concrete pipe bell, wherein the concrete pipe comprises a bell, a hub and a pipe, the bell and the hub are fixedly installed in a pipe core which is arranged at two ends of the pipe, a ring-shaped flute is prepared on the outer wall of the concrete pipe hub radially and axially. The seal structure has the advantages of simple structure, scientific and reasonable design, low preparation cost, simple technique, reinforcing the seal property among concrete pipes effectively through the ring-shaped flute structure, which improves the entire seal level of the concrete pipe line.
Description
Technical field
The utility model relates to concrete pipe, especially a kind of sealing configuration of pipe faucet of concrete.
Background technique
The large diameter concrete pipe road adopts steel bell and spigot more in the prior art, and its advantage is mainly reflected in: 1. steel bell and spigot intensity height, and anti-collision capacity is strong; 2. easy for installation, constructing operation is simple; 3. impermeability is stronger.Generally be shaped on the shaped steel of single groove or double flute at the socket outer wall of steel bell and spigot, establish seal ring in the groove, though can reach the effect of sealing, fabricating cost is higher, has influenced the cost performance of whole tubing; And be shaped on groove on the existing socket, and the stupefied easy scuffing O-ring seal in limit at the process further groove top that O-ring seal is installed, thus sealability reduced, even influence the sealability of whole pipeline.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of sealing configuration of simple in structure, reasonable in design, the simple pipe faucet of concrete of technology is provided.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of sealing configuration of pipe faucet of concrete, concrete pipe is made of bellmouth, socket, body, and bellmouth, socket be coaxial to be packed in the tube core at body two ends, it is characterized in that: at the radially coaxial annular groove that is shaped on of the outer wall of concrete pipe socket.
And the sectional shape of described annular groove is semicircle, oval or square.
And the bellmouth of described concrete pipe is provided with 0-30 ° camber angle at the front end that cooperates with socket.
And, be embedded with O-ring seal in the described annular groove.
Advantage of the present utility model and beneficial effect are:
1. this concrete pipe coaxial annular groove that radially is shaped on the socket outer wall, this groove need not forging and pressing, and preparation process is simple, has saved fabricating cost, has improved the output efficiency of socket.
2. the bellmouth of this concrete pipe is provided with 0-30 ° camber angle at the front end that cooperates with socket, makes things convenient for the installation of pipeline, and O-ring seal is installed in the socket annular groove, has strengthened the sealing of pipe joint, and the O-ring seal installation is comparatively convenient.
3. the utility model overall structure is simple, and design science is reasonable, low cost of manufacture, and technology is simple, and the circular groove structure of setting can effectively strengthen the sealability between the concrete pipe, improves the integral sealing level of concrete pipelines.
Description of drawings
Fig. 1 is the utility model overall structure schematic representation (broken section);
Fig. 2 is the broken section enlarged view of two concrete pipe connection parts.
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The sealing configuration of this pipe faucet of concrete, its concrete pipe is made of bellmouth 1, socket 4, body 3, and bellmouth, socket are packed in the tube core 2 at body two ends.Innovation point of the present utility model is: at the radially coaxial annular groove 5 that is shaped on of the outer wall of concrete pipe socket, be embedded with O-ring seal 6 in this annular groove.When two concrete tube bodies were connected, the sealing cushion rubber can effectively seal the gap (referring to Fig. 2) between socket and the bellmouth.
The sectional shape of annular groove is semicircle, oval or square, and the present embodiment accompanying drawing is depicted as semicircle.
For making things convenient for piping erection, be provided with 0-30 ° camber angle at the front end that cooperates with socket at the bellmouth of concrete pipe.
Claims (4)
1. the sealing configuration of a pipe faucet of concrete, concrete pipe is made of bellmouth, socket, body, and bellmouth, socket be coaxial to be packed in the tube core at body two ends, it is characterized in that: at the radially coaxial annular groove that is shaped on of the outer wall of concrete pipe socket.
2. the sealing configuration of pipe faucet of concrete according to claim 1 is characterized in that: the sectional shape of described annular groove is for semicircle, oval or square.
