Abstract

A pollution discharge, gas discharge pipe connection includes a connection main body formed by plastics connecting with an interface, characterised that a seal slot arranging with a seal ring is formed in inner wall of the interface while the seal ring connecting with an outer wall of the pipe. The technology scheme is a flexibility connection which is capable of automatic regulation, always maintaining in a seal state with reliably performance even though the pipe moves ( e.g. expands on heating and contracts on cooling or offsets center line of assembling).

Description

Blowdown, exhaust fitting

Technical field

The utility model relates to the pipe joint that sewer, waste discharge gas are used, and belongs to the capital construction accessory.

Background technology

In city-building, industrial and mining enterprises' capital construction, and during country house builds, all need to install blow-off pipe, what have also need install stack (waste gas), between each root of blowdown, stack, particularly must link to each other with pipe joint at the pipeline crotch.Pipe joint not only kind is a lot, for example two logical, threeway, four-way, and elbow etc.And the material of making also has nothing in common with each other, and it is commonly used metal tube, plastic pipe and pipe of cement etc.The major defect that existing blowdown, exhaust fitting exist has: the one, and adopt gluing bonding between tube outer wall and the inner nosepiece wall, in case elongation takes place or shrink (expanding with heat and contract with cold), rubberised layer is separated, lose sealing function; The 2nd, the interface of joint is flat mouthful of thin-walled entirely, only is applicable to the gluing sealing, and is unfavorable for the insertion (particularly threeway radially, four-way connection) of pipe again; The 3rd, the corner of joint endoporus is a straight transitions, causes passage little, and resistance is big, and flow velocity is slow; The 4th, the joint outer wall does not have girth member, bad mechanical strength; The 5th, mostly the joint of present larger caliber generally is the Metal Material Welding moulding, the processing trouble.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, it is flexible sealing that a kind of interface of joint and the junction of pipe are provided, and can regulate voluntarily, and pipe is pegged graft or pulled out and unload conveniently, joint endoporus corner smoothness, blowdown, exhaust fitting that joint outer wall mechanical strength is good.

The technical scheme of the utility model blowdown, exhaust fitting is: the adapter body that is made of plastics, and main body is connected with interface, it is characterized in that being shaped on seal groove in the inwall of interface, and sealing ring is installed in the seal groove, and sealing ring contacts with tube outer wall.The technical program is shaped on seal groove in interface, sealing ring is arranged in the seal groove, by sealing ring and tube outer wall contact seal, be that a kind of flexible sealing connects, be not afraid of pipe and move (as expand with heat and contract with cold or depart from mounting center line etc.), the capital is regulated voluntarily, remains sealing state, dependable performance.

Blowdown of the present utility model, exhaust fitting have enlarging (or claim R mouth) on its interface, seal groove so be particularly suitable for sealing ring is installed in the endoporus, and helps the insertion of pipe in enlarging.In actual product, can be existing flat mouthful of its interface or the mixing pattern of enlarging is arranged again.The corner of its joint endoporus is an arc transiting surface, is beneficial to remove obstacles and dirt flows, and makes dirt be difficult for tangling, and removes obstacles conveniently with instruments such as manipulators, makes flow resistance little, and sectional area is big, and is very smooth.Outer wall in adapter body and interface junction is shaped on reinforcing rib, improves mechanical strength.Its described reinforcing rib is straight muscle or different shapes such as diagonal bar or netted reinforcing rib.Outer wall at joint is shaped on locating piece, and is easy for installation stable.Its described joint is two pass joints or the various terminals such as tee junction or four-way connection of injection mo(u)lding.Its joint also comprises it being elbow of injection mo(u)lding etc.

The specific embodiment

The utility model discloses a kind of blowdown, exhaust fitting, as shown in Figure 1, the adapter body 1 that is made of plastics, main body is connected with interface 2, and interface can be a plurality of, as two, three, four etc., its major technology is characterised in that in the inwall of described interface 2 and is shaped on seal groove 3, sealing ring 4 is installed in the seal groove 3, and sealing ring contacts with tube outer wall, and it is bonding to overcome the prior art gluing, segregative shortcoming, this sealing ring sealing also claims flexible sealing, and as with rubber seal etc., sealing performance is very reliable, when variations such as pipe displacements, as the elongation or shorten of expanding with heat and contract with cold, and when departing from the mounting center line, all fully can be adjusted voluntarily.Enlarging 8 is arranged on interface, and seal groove is in enlarging, and enlarging also claims the R mouth, both has been applicable to the installation sealing ring, helps the insertion of pipe again.But in actual product, its joint not necessarily all is enlarging, and its interface 2 is flat mouthful 10 or has enlarging 8 to mix use mutually.For example in a joint, there is an enlarging that flat mouthful or two enlargings are arranged not only but also mixed type joint such as flat mouth is arranged.The corner 5 of joint endoporus is an arc transiting surface, makes to flow very smooth and easyly, does not block, and removes obstacles conveniently, and robotic arm is removed obstacles.Outer wall in adapter body 1 and interface junction is shaped on reinforcing rib 6, increases mechanical strength, firm and durable.Implement in the production concrete, the shape of its described reinforcing rib is straight muscle or various schemes such as diagonal bar or netted reinforcing rib.The outer wall of its joint is shaped on locating piece 7, and is easy for installation, reliable.Its joint is two pass joints (as 3, shown in Figure 4) or various types of joints such as tee junction or four-way connection of injection mo(u)lding, as shown in Figure 1 and Figure 2, and large-diameter pipe mouth 9 is arranged.Its joint also comprises it being the various terminals such as elbow of injection mo(u)lding, as elbows such as 45 °, 60 °, 90 °, is not limited to shown in the accompanying drawing.
