Abstract
The invention relates to a bell mouth ring boss sealing structure in a concrete reinforced pipe bell and faucet. The concrete reinforced pipe consists of a bell mouth, a faucet and a pipe; the bell mouth and the faucet are coaxially and fixedly arranged in a pipe core at the two ends of the pipe; wherein, an inner wall of the concrete reinforced pipe bell is coaxially and fixedly provided with an inner ring bulge platform along the radial direction; an outer wall of the concrete reinforced pipe bell is coaxially and fixedly provided with an outer ring bulge platform along the radial direction. The invention has the advantages of simple integral structure, scientific and reasonable design, low construction cost and simple technique; the bulge platform can increase the sealing property between concrete reinforced pipes and raise the integral sealing level of concrete reinforced pipes.
Description
Technical field
The present invention relates to concrete pipe, especially a kind of bell annular boss sealing structure of pipe faucet of concrete.
Background technique
The tubing joint socket is one of key link of the whole pipeline seal of decision.Available coagulation soil tubing joint socket generally is divided into two classes according to material: 1. concrete material, joint socket and concrete tube core one moulding by casting; 2. shaped steel material, steel bell and spigot is packed in the two ends of concrete tube core.At present the large diameter concrete pipe road adopts steel bell and spigot more, 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.The socket outer wall of general steel bell and spigot is single groove or dual-slot structure, establish seal ring in the groove, but the socket complex manufacturing technology of this kind structure need forging forming, and fabricating cost is higher.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, design science is reasonable, the bell annular boss sealing structure of the simple pipe faucet of concrete of technology.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of bell annular boss sealing structure of pipe faucet of concrete, its concrete pipe is made of bellmouth, socket and body, bellmouth, socket be coaxial to be packed in the tube core at body two ends, it is characterized in that: be fixed with ring boss in that the inwall of concrete pipe bellmouth is radially coaxial.
And, at the radially coaxial outer shroud boss that is fixed with of the outer wall of concrete pipe socket.
And when the bellmouth of concrete pipe was connected with socket, the outer shroud boss that interior ring boss and the socket that bellmouth installed installed was for shifting to install and be embedded with O-ring seal therebetween.
And the bellmouth of described concrete pipe is provided with 0-30 ° camber angle at the front end that cooperates with socket.
Advantage of the present invention and beneficial effect are:
1. all coaxial boss that radially is fixed with of bellmouth inwall of this pipe faucet of concrete and socket outer wall is made annular boss and be need not forging and pressing, and technology is simple, has saved fabricating cost, has improved the output efficiency of joint socket.
2. the bellmouth of this pipe faucet of concrete is provided with 0-30 ° camber angle at the front end that cooperates with socket, socket can slip in the bellmouth smoothly when tubing was installed, and the sealing by the O-ring seal between the boss, effectively strengthened the sealing of pipe joint, and O-ring seal is easy for installation.
3. overall structure of the present invention is simple, and design science is reasonable, low cost of manufacture, and technology is simple, and the boss 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 a general structure schematic representation of the present invention (broken section);
Structure amplification view when Fig. 2 is two concrete tube bodies connections.
Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
The bell annular boss sealing structure of this pipe faucet of concrete, its concrete pipe is made of bellmouth 1, socket 5 and body 4, and bellmouth, socket be all coaxial to be packed in the tube core 3 at body two ends.Innovative point of the present invention is: encircle boss 2 in one radially coaxial being fixed with of the inwall of concrete pipe bellmouth, at the radially coaxial outer shroud boss 6 that is fixed with of the outer wall of concrete pipe socket, outer shroud boss and interior ring boss all can adopt welding manner to install.When the bellmouth of concrete pipe was connected with socket, the outer shroud boss that interior ring boss and the socket that bellmouth installed installed was for shifting to install and setting-in O-ring seal 7 (referring to Fig. 2) therebetween.
For ease of being connected between bellmouth and the socket in place, the bellmouth of concrete pipe is provided with the camber angle of θ=0-30 ° at the front end that cooperates with socket, this camber angle the best is 15 °.
Claims (4)
1. the bell annular boss sealing structure of a pipe faucet of concrete, its concrete pipe is made of bellmouth, socket and body, bellmouth, socket be coaxial to be packed in the tube core at body two ends, it is characterized in that: be fixed with ring boss in that the inwall of concrete pipe bellmouth is radially coaxial.
2. the bell annular boss sealing structure of pipe faucet of concrete according to claim 1 is characterized in that: at the radially coaxial outer shroud boss that is fixed with of the outer wall of concrete pipe socket.
