Description
The utility model relates to a kind of heat distribution pipeline compensation device.
In the heat distribution pipeline design process, compensate pipeline because the amount of deformation that expands with heat and contract with cold and cause with compensation device usually.As " a kind of high-pressure sleeve type telescoping unit " of Chinese patent CN2088632 report is the external pressure plate on the expansion bend short tube of being enclosed within by the round tube cavity of the flexible body of packing into, big flange plate one end, can't bluely coil a client link with the expansion bend short tube be the interior platen of one, interior platen and expansion bend short tube are connect the all-in-one-piece retaining screw, fill in the filler in the cavity volume that forms by expansion bend short tube, interior platen and expansion bend body, external pressure plate and expansion bend sports association are become the coupling bolt of one and form.This compensator compensates amount is little, complex structure; Flexible compensation device has also appearred, " pipeline flexible expansion bend " as Chinese patent CN2058955 report introduced a kind of flexible expansion bend, the expansion bend body that comprises the two flange arrangements of reducing, by the flange platen celloidin seal ring on the expansion bend body and pass the telescopic pipe that the flange platen stretches into the expansion bend body and clamped by rubber seal tightly, can rotate relatively between this expansion bend body and telescopic pipe, but it is axial stretching, but axially dumb during rotation compensation.
The purpose of this utility model is to overcome above-mentioned deficiency, and the rotary compensator that a kind of rotation compensation is flexible, compensation rate is big is provided.
The utility model can be realized like this: rotary compensator, comprise interior pipe, steel tubing in different shapes joint, outer sealing seat, sealing material and the flange gland of being provided with of interior pipe, hold-down bolt makes sealing seat be connected with the flange gland, the flange gland is connected with locating flange and adjusting screw, is provided with ball between the pipe in locating flange and the rotation, and the junction of interior pipe and steel tubing in different shapes joint is provided with boss, and form groove between the sealing seat, be provided with ball in the described groove.
The utility model compensation rate is big, and pipe can freedom and flexibility rotate the needs that satisfy the pipeline thermal force compensating in the rotation, and is simple in structure, easy to maintenance.
Fig. 1 is a structural representation of the present utility model.
Further specify the utility model below by embodiment.
With reference to figure 1, rotary compensator, comprise interior pipe (1), steel tubing in different shapes joint (8), outer sealing seat (6), sealing material (5) and the flange gland (4) of being provided with of interior pipe (1), hold-down bolt (9) makes sealing seat (6) be connected with flange gland (4), flange gland (4) is connected with locating flange (3) and adjusting screw (2), be provided with ball (71) between locating flange (3) and the interior pipe (1), interior pipe (1) is provided with boss (10) with the junction of steel tubing in different shapes joint (8), and sealing seat forms groove between (6), is provided with ball (72) in the described groove.The utility model compensation rate is big, and is flexible, also is convenient to maintenance.In application, the steel tubing in different shapes joint inserts in the heat distribution pipeline, and when the need thermal compensation, interior pipe (1) can rotate, and generally uses two or more the utility model in heat distribution pipeline, and compensation rate is bigger like this, and flexibility is better.
Claims (1)
1, rotary compensator, comprise interior pipe (1), steel tubing in different shapes joint (8), outer sealing seat (6), sealing material (5) and the flange gland (4) of being provided with of interior pipe (1), hold-down bolt (9) makes sealing seat (6) and flange gland (4) be connected, it is characterized in that flange gland (4) is connected with locating flange (3) and adjusting screw (2), be provided with ball (71) between locating flange (3) and the interior pipe (1), interior pipe (1) is provided with boss (10) with the junction of steel tubing in different shapes joint (8), and sealing seat forms groove between (6), is provided with ball (72) in the described groove.
