Abstract
The utility model discloses a gland-free type telescopic device, which comprises an insertion pipe (1) and a connection pipe (4). One end of the insertion pipe (1) is inserted into one end of the connection pipe (4) and can longitudinally slide along the inner cavity of the connection pipe (4), the insertion pipe (1) and the connection pipe (4) are in liquid seal, and a flange (6) is fixedly connected with the other ends of the insertion pipe (1) and the connection pipe (4) respectively. The gland-free type telescopic device is characterized in that screws (2) are inserted inside a plurality of corresponding through holes of the two flanges (6), and nuts (5) are connected with the screws (2) on the two side surfaces of the flanges (6). The gland-free type telescopic device can realize connection only by directly connecting with the fastening nuts on the flanges, so gland-free type telescopic device is extremely convenient to assembly and dissemble, and the labor productivity is greatly improved. Meanwhile, the gland-free type telescopic device prevents the insertion pipe from being easily detached from the connection pipe.
Description
Technical field
The utility model relates to slip joint, exactly is a kind of expansion bend that does not need the gland retractable.
Background technique
In industrial and agricultural production, pipeline is commonly used to the delivering liquid medium.Owing to reason such as be difficult to accomplish accurately to determine length or expand with heat and contract with cold, expansion bend commonly used cooperates the installation of pipeline to pipeline when mounted.As Chinese publication number is that the patent documentation of CN2121598 is exactly a kind of expansion bend.Above-mentioned expansion bend is by being connected and fixed by bolt after the flange butt joint again.Because the nut that uses when installing and the bolt of cooperation are many, installation and dismounting are very time-consuming, inefficiency.Because two telescopic pipe ends are sleeved on together, do not have limit stoper simultaneously, very easily cause between two telescopic pipes to break away from mutually.
The model utility content
The purpose of this utility model solves above-mentioned expansion bend exactly and installs and remove difficulty, inefficiency, and the problem that easily breaks away from mutually.
The technical solution adopted in the utility model is: non-bonnet (NB) formula expansion bend, it comprises intubate and the adapter together of two end mutual sheathing, intubate one end inserts to take in the end and also can slide before and after taking over inner chamber, liquid sealing between intubate and the adapter, the other end of intubate and adapter is connected with flange respectively, be interspersed with screw rod in it is characterized in that on several corresponding through holes of two flanges, be connected with nut on the screw rod of flange bi-side.
Adopt technique scheme, Panasonic of elder generation flange nut outside during use, the nut that rotates two flange inboards can position intubate and adapter, as long as treating that the connection orchid penetrates on the bolt, set screw nut can be realized connecting again.
The utility model beneficial effect is: because the direct upper flange tightening nut that connects of the utility model employing can be realized connecting, therefore installation and dismounting are all very convenient, have improved labour productivity greatly; Also can make simultaneously intubate and take over and be difficult for breaking away from.

Embodiment
The utility model non-bonnet (NB) formula expansion bend, as shown in Figure 1, it comprises intubate 1 and the adapter 4 together of two end mutual sheathing, intubate 1 one ends insert to take in 4 one ends and also can slide before and after taking over 4 inner chambers, intubate 1 and take over 4 between liquid sealing, intubate 1 and take on several corresponding through holes that the other end of 4 is connected with 6, two flanges 6 of flange respectively in be interspersed with screw rod 2, be connected with nut 5 on the screw rod 2 of flange 6 bi-side.
