Abstract
The utility model relates to an improved rotary type compensating apparatus, which belongs to a compensating apparatus for a thermal pipeline and comprises an inner pipe and a shaped pipe joint, wherein, the outer part of the inner pipe is provided with a sealing seat and a press cover flange which are connected by a pressing bolt, a dummy club is arranged on the inner pipe of the combining point of the inner pipe of the shaped pipe joint, and a ball is arranged in a groove formed between the dummy club and the sealing seat; a groove with an opening facing to the inner pipe is arranged in the press cover flange, and a ball is arranged in the groove. The utility model is installed in the thermal pipeline. When the thermal pipeline needs thermal compensation, the inner pipe can be rotated so that compensation rate is enlarged and adaptability is wider. The utility model has reliable quality, convenient installation and little maintenance quantity.
Description
Technical field
The utility model relates to a kind of heat distribution pipeline compensation device.
Background technique
Chinese patent CN98227061.5 discloses a kind of " rotary compensator ", by interior pipe, the steel tubing in different shapes joint is formed, the outer sealing seat that is provided with of interior pipe, sealing material and flange gland, hold-down bolt makes sealing seat be connected with the flange gland, the flange gland connects locating flange and adjusting screw, be provided with ball between the pipe in locating flange and the rotation, interior pipe is provided with boss with the junction of steel tubing in different shapes joint, and forms groove between the sealing seat, and ball is set in the groove, this device rotation compensation is flexible, compensation rate is big, but the flange gland adds the location flange, this combination of adjusting screw and ball, gold machining precision and assembly precision are difficult to control, product is poor reliability when normal the use, increase amount of maintenance, in addition, the length of interior pipe in steel tubing in different shapes is short, flowing medium can produce eddy current at the volley, has directly increased the pressure loss of flowing medium.
Summary of the invention
The utility model in order to overcome above-mentioned deficiency, provides a kind of reliable product quality just, is convenient to the few whirl compensator of installation, maintenance amount.Main improvement of the present utility model is to cancel locating flange and the adjusting screw that is connected with the flange gland, directly on gland flange, offer the groove of a placement ball, specifically be achieved like this: improved rotary compensator, comprise interior pipe, the steel tubing in different shapes joint, outer sealing seat and the gland flange that connects with hold-down bolt that be equipped with of interior pipe, with be equipped with a boss on the interior pipe at the steel tubing in different shapes joint place of combining, be provided with ball in the groove that forms between boss and the sealing seat, it is characterized in that being provided with in the gland flange groove of opening, be placed with ball in the described groove facing to interior pipe.By setting up the groove in the gland flange, just can omit locating flange and adjusting screw, not only structure is more succinct, installation is more convenient, and has guaranteed processing and assembly precision, has improved reliability of products, has significantly reduced the maintenance probability.
The utility model has also further increased the length of interior pipe in the steel tubing in different shapes joint, and interior pipe prolongs the mid-rear portion that extends the steel tubing in different shapes joint from the steel tubing in different shapes splice port, and like this, fluid is difficult for producing eddy current at the volley, and the pressure loss of medium is little.
The utility model produces dislocation in the other direction and ball displacement, comes off in order to prevent product in the project installation process, the steel tubing in different shapes joint is built-in with limiting stopper.
The utility model is installed in the heat distribution pipeline, and when the needs thermal compensation, interior pipe can rotate, and compensation rate is increased, and adaptability is wider, and have more easy assurance quality of product, do not produce fluid vortex, prevent to install in the reverse advantage of dislocation.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
