Abstract
The utility model discloses a multifunctional pipeline expanded device, mainly composed of a sleeve tube, an inserting tube partly inserted into the sleeve tube, a pressure tube, a swaging groove and a sealing filler. The end head of the inserting end of the inserting tube 3 is provided with an anticreep spacing pin 4, and the corresponding inner part of the sleeve tube 1 near the side of the swaging groove is provided with an anticreep spacing boss 5. The swaging groove 6 forms a ladder structure, and the outer surface of the inserting side of the inserting tube 3 is provided with an installing and a running reticles 8 and 9. Consequently, the utility model has the advantages of one article with multiple use, wear resistance, no easy rust and not easy pulling out.
Description
The utility model relates to a kind of pipeline extension device, especially the pipeline extension device that is made of sleeve pipe, intubate, gland, stuffing box packing, binder groove.
Classification pipeline extension device on the Domestic market mainly contains sleeve pipe at present, and intubate, gland, sealing material, binder groove constitute, and casing inner diameter is less relatively, is difficult for wildcard GB tubing, can only product one usefulness.Simultaneously, sleeve pipe and intubate matching gap are less, it is dead that rust takes place behind the installation and operation easily, lose stretchability, and the binder groove of existing pipe expansion bend is rectangular configuration, in it during the stuffing box packing pressurized distortion bigger, easy to wear aging, in addition, existing product is not set up defences yet and is taken off limit stoper, takes off the accident of pulling out easily.Intubate is not established the operation graduation line yet, and inconvenience is installed.
The purpose of this utility model provides wear-resistant that a kind of product use more, and is not easy rusting dead, is difficult for taking off the pipeline extension device that pulls out.For achieving the above object, the technical solution adopted in the utility model is: existing pipeline extension device is made improvements, the internal diameter of sleeve pipe gland is than the big 1%-3% of cannula outer diameter, intubate adopts GB tubing, the end of intubate insertion portion is provided with the anticreep position-limitting pin, and it is corresponding with position-limitting pin that inside pipe casing is provided with the anticreep positive stop lug boss near binder groove side.
Above-mentioned binder groove is a trapezium structure
The outer surface of the insertion end of above-mentioned intubate is provided with the installation and operation groove.
The internal diameter of sleeve pipe (1), gland (2) adopts GB tubing than the big 1-3% of external diameter, the intubate (3) of intubate (3).
Owing to adopt such scheme, sleeve pipe is more bigger than the external diameter of the intubate that adopts GB tubing with the internal diameter of gland, so can be arbitrarily made with two flange-types according to requirement of engineering in a side of pipeline extension device, multi-form pipeline expansion devices such as tray formula, plug in tray embody the many usefulness of product.Simultaneously, big gap between intubate and sleeve pipe, it is dead to be difficult for that rust takes place, front end at insertion tube is provided with the anticreep position-limitting pin, and is corresponding with the anticreep positive stop lug boss of inside pipe casing, constitutes the anticreep limit stoper, the difficult accident of pulling out of taking off, in addition, on the surface of insertion tube inserting side, be provided with the installation and operation groove, be convenient to install.
Be that embodiment elaborates to the utility model below with the accompanying drawing.
Fig. 1 is two flange-type pipeline extension device organigrams.
Fig. 2 is single flange-type pipeline extension device organigram.
In Fig. 1, intubate 3 adopts GB 3420-82D2 standard tubing, the internal diameter of sleeve pipe 1 and gland 2 is than the big 1%-3% of internal diameter of intubate 3, intubate 3, sleeve pipe 1 and gland 2 can be magnesium iron, graphitic pig iron, malleable iron, stainless steel, materials such as plastics constitute, binder groove 6 is a trapezium structure, so be difficult for wear and aging during stuffing box packing 7 pressurizeds in the binder groove 6, stuffing box packing 7 can be multiple filler, as general O type cushion rubber etc., end in intubate 3 insertion ends is provided with anticreep position-limitting pin 4, is provided with anticreep positive stop lug boss 5 in the inside of sleeve pipe 1 near binder groove 6 sides simultaneously, and the two is corresponding, constitute the anticreep limit stoper, effectively anti-anti-avulsion is dialled accident; Be provided with the installation and operation groove in addition on the outer surface of intubate 3 inserting sides, comprise minimal fitting line 9, best assembly line 8 etc. are convenient to install.
In Fig. 2, intubate 3 is mouthing or difference mouthful formula intubate, according to said structure, can obtain single-deck formula pipeline extension device.
Claims (4)
- A kind of multifunctional pipe expansion bend, mainly contain that sleeve pipe and part are inserted the intubate of sleeve pipe and pressure pipe, binder groove, stuffing box packing constitutes, it is characterized in that: the end of intubate (3) insertion portion is provided with anticreep position-limitting pin (4), and it is corresponding with anticreep position-limitting pin (4) that the inner close binder groove (6) of sleeve pipe (1) locates to be provided with anticreep positive stop lug boss (5).
- 2, pipeline extension device according to claim 1 is characterized in that binder groove (6) is a trapezium structure.
