Sealed type rotation compensator with V-shaped end faces

Abstract

The invention discloses a sealed type rotation compensator with V-shaped end faces. The sealed type rotation compensator comprises an inner pipe, a gland, a bolt, padding, an anti-attrition mat and a sealing socket. The inner pipe and the padding which are in coaxial fit with the sealing socket are axially limited through an inwards-convex circular bead, the gland arranged on the inner pipe in a sleeving manner is connected with the sealing socket through the bolt, and the pressed gland applies pressure to the padding to form an adjustable shaft sealing structure for the inner pipe relative to the sealing socket. According to the sealed type rotation compensator, the end faces where an inwards-convex circular bead of the sealing socket and an outwards-convex circular bead of the inner pipe are matched are in V-shaped embedded type fit, and the end faces where the inwards-convex circular bead of the sealing socket and the outwards-convex circular bead of the inner pipe are combined are separated through the anti-attrition mat. According to the sealed type rotation compensator, the V-shaped end faces where the sealing socket and the inner pipe are matched are actually positive and negative conical surface combination bodies, the self-centering effect is achieved during pairing, the most advantage of fixed shaft rotation is that the self compensation ability is achieved when the conical surfaces are abraded, and therefore the sealing performance of the sealing structure is stable and durable. Additionally, the paired V-shaped end faces are curve faces, and the bending structure has the pressure damping capacity and the dual sealing effect, so that the sealed type rotation compensator is particularly suitable for mating under the high temperature and high pressure working conditions.

Description

Technical field [0001] The present invention relates to a pipeline safety device, in particular, the present invention relates to a pipeline compensator, particularly a rotary compensator. Background technique [0002] During the operation of the heating pipe network, a corresponding amount of displacement and blind plate thrust will be generated as the pressure, temperature and ambient temperature of the built-in medium change. Although these physical changes are normal, they are extremely destructive, and will easily cause damage to the thermal pipe network and supporting equipment if not treated. Therefore, necessary pipeline compensation devices must be installed at the relevant nodes of the thermal pipe network during engineering design. Nowadays, the rotary compensator is the first choice for the supporting pipeline compensator of high temperature and high pressure thermal pipe network. Rotary compensator is a new type of pipeline compensation device that integrates the a...
