Description

A kind of sealing and connecting device of socket joint nozzle
Technical field
The utility model belongs to nozzle interconnection technique field, is concretely related to a kind of sealed connection dress of socket joint nozzle It sets, is particularly suitable for socket steel pipe in the sealed connection of bellmouth reinforced concrete pipe.
Background technique
Socket joint connection is pipeline or the common connection type of pipe fitting, is the loudspeaker straight coupling that jack tube is extend into socket pipe It is inside fixed, some also fills sealing material in the annular space that socket joint combines, and has reached sealed connection effect.Socket joint is connected to It is widely used in power station water supply pipeline, mainly the nozzle connecting portion in steel pipe and reinforced concrete pipe.At present steel pipe with The bell and spigot frame of reinforced concrete pipe has the following problems:First, the socket joint of steel pipe and reinforced concrete pipe is connected as being rigidly connected, season Section variation causes the dilation of steel pipe and reinforced concrete pipe asynchronous, and relative position variation, socket joint have occurred for bell and spigot frame Sealing material in annular space is caused seal failure by frictional dissipation;Second, steel pipe circumferential direction is shunk after winter temperature sharply declines Increase, making the socket joint annular space of steel pipe and reinforced concrete pipe is more than that the thickness of sealing material causes drainage, and pipeline is located at ground Lower inconvenient maintenance, time and effort consuming, expense cost are high.
Utility model content
The purpose of this utility model is just to provide a kind of structure socket joint that is simple, easy to use, being tightly connected effect stability The sealing and connecting device of nozzle.
To achieve the above object, technical solution used by the utility model is:
A kind of sealing and connecting device of socket joint nozzle, it is characterised in that:Including being respectively arranged at socket tube end and bellmouth First hoop muzzle pipe of tube end and the second hoop muzzle pipe, the first hoop muzzle pipe and second bind round muzzle pipe ring to fixed setting First retaining ring and the second retaining ring, first retaining ring and the second retaining ring are connected with multiple caging bolts.
The additional technical feature for constituting a kind of sealing and connecting device of above-mentioned socket joint nozzle further includes:
--- the one or multi-channel sealing rubber ring of setting in the annular space that the jack tube is connect with the socket pipe socket joint;
--- the caging bolt is arranged along the even circumferential of first retaining ring and the second retaining ring;
--- the tightening nut of the caging bolt is set on first retaining ring and/or the second retaining ring.
A kind of sealing and connecting device of socket joint nozzle provided by the utility model compared with the existing technology, has following excellent Point:First, one end due to device connection is made of the fixed retaining ring of hoop muzzle pipe and its circumferential direction, the gear at bell and spigot frame both ends Between circle there are multiple caging bolts to be connected and fixed, structure member is easily fabricated and quick for installation, has the characteristics that structure is simple; Second, it is firm to connect, and energy since caging bolt can both guarantee that socket steel pipe and bellmouth reinforced concrete pipe socket joint were fixed Both prevent from expanding with heat and contract with cold it is asynchronous misplace, protect the sealing material in socket joint annular space not to be worn;Third, due to The tightening nut of caging bolt is set on the first retaining ring and/or the second retaining ring, and after winter temperature sharp fall, socket steel pipe is circumferential Shrink cause socket joint annular space be more than sealing material thickness when, can by tightening nut adjust socket steel pipe insertion depth with Achieve the purpose that reduce socket joint annular space, there is easy to use, the stable feature of sealing effect.
Detailed description of the invention
Fig. 1 is to constitute a kind of structural schematic diagram of socket joint nozzle sealing and connecting device of the utility model.
Specific embodiment
With reference to the accompanying drawing to a kind of structure and work of socket joint nozzle sealing and connecting device provided by the utility model Principle is described in further detail.
It is a kind of structural schematic diagram of socket joint nozzle sealing and connecting device provided by the utility model referring to Fig. 1.It constitutes The structure of the sealing and connecting device includes being respectively arranged at the first hoop 11 He of muzzle pipe of 2 end of 1 end of jack tube and socket pipe Second hoop muzzle pipe 21, the first hoop muzzle pipe 11 and 21 the first retaining ring 12 of circumferential fixed setting of the second hoop muzzle pipe and the second retaining ring 22, the first retaining ring and the second retaining ring are connected with multiple caging bolts 3.
Its working principle is that:By first hoop muzzle pipe 11 and second hoop muzzle pipe 21 be separately fixed at 1 end of jack tube and 2 end of socket pipe is connected between circumferential direction fixed the first retaining ring 12 and the second retaining ring 22 with multiple caging bolts 3, caging bolt 3 Both jack tube 1 and the engaging of 2 socket joint of socket pipe had been guaranteed securely, sealing is tight, and can prevent the two from relative displacement occurs.
In constituting a kind of above-mentioned structure of socket joint nozzle sealing and connecting device,
--- in order to further improve the sealing effect of socket joint binding site, above-mentioned jack tube 1 and 2 socket joint of socket pipe The one or multi-channel sealing rubber ring 4 of setting in the annular space of connection, caging bolt 3 can prevent jack tube 1 and the dislocation of socket pipe 2 from causing Abrasion to sealing rubber ring 4;
--- preferably, above-mentioned caging bolt 3 is arranged along the even circumferential of the first retaining ring 12 and the second retaining ring 22, limits spiral shell Bolt 3 is balanced in the axial direction to the pulling force of socket pipe 2 and jack tube 1, keeps socket joint connection more firm, sealing effect is more steady It is fixed;
--- for the ease of adjust socket joint depth, the tightening nut 31 of above-mentioned caging bolt 3 be set to the first retaining ring 12 or On second retaining ring 22, if caging bolt 3 all has tightening nut 31 at the first retaining ring 12 and the second retaining ring 22, both ends are same When tighten, keep jack tube 1 and 2 relative motion of socket pipe more safe and reliable, operate it is more quick.
