Problems solved by technology

However, the structure cannot be adjusted after wear, and the parts of the rolling structure are easy to scale or oxidize and rust in the medium, which significantly reduces the flexibility of relative rotation

Embodiment Construction

[0012] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0013] The rotary pipeline compensator shown in the drawings includes a main flow pipe 1, a nut 2, a gland 3, a screw 4, a sealing ring 5, a casing 6, a packing 7 and a casing 8. The main flow pipe 1 is inserted from the right end of the casing 6, and the annular boss on the outer wall of the left end of the main flow pipe 1 is matched with the inner hole of the casing 6 as a clearance fit. There is a sealed cavity between the main body outer wall of the main flow pipe 1 and the inner hole of the casing 6, from left to right The sealing ring 5, the packing 7, the sleeve 8, the packing 7 and the gland 3 are plugged in sequence on the right side. There are evenly distributed through holes on the end faces of the shell 6 and the gland 3. The screw rod 4 penetrates into the through hole and is connected by the nut 2 to press The cover 3 and...

Abstract

The invention discloses a rotary pipeline compensator, which comprises a main flow pipe, a nut, a gland, a screw, a seal ring, an outer shell, filler and a bushing. The main flow pipe is inserted from the right end of the outer shell; a boss at the left end of the main flow pipe is in clearance fit with an inner hole matched with the outer shell; a sealing cavity is reserved between the main body of the main flow pipe and the inner hole of the outer shell; the seal ring, the filler, the bushing, the filler and the gland are arranged from left to right; the outer shell is integrally connected with the gland through the screw and the nut; the filler is pre-compressed by the gland; and the main flow pipe can rotate opposite to the outer shell. When the compensator runs, the pressure of a medium is introduced from an axial reserved gap between the main flow pipe and the outer shell so as to push the main flow pipe to move rightwards and further compress the filler through the seal ring to directly improve the sealing performance. The invention is suitable for rotary pipeline compensators with various specifications.

Description

technical field [0001] The invention relates to a pipeline compensator, in particular, the invention relates to a rotary pipeline compensator which uses a fitting structure between inner and outer sleeves to rotate. Background technique [0002] The pipeline compensator is an important device to realize the safe operation of the heat pipe network. There are many structural forms. The bellows type, the ball type and the sleeve type are the three common structural forms. Pipeline compensators with different structures have different compensation performances. Each form has advantages and disadvantages. For example, the sleeve type compensator with rotation compensation is characterized by simple structure and high pressure resistance, and has been widely used in engineering. However, due to the short overlapping portion of the inner and outer casings in the prior art, the stability during rotation is poor, and the inner and outer casings are prone to deflection, thereby incre...
