  • the technical problem being solved by this technical solution is the creation of an effective and compact flange suitable for mass production by modem technological means, as well as the expansion of flanges range.
  • the technical result which allows to solve this problem, consists in increasing the bearing capacity of the flange due to the fact that the central and peripheral parts of the flange have improved geometric and strength characteristics, providing for the increased reliability and durability of its operation, the allowable number of repair and other assembly and disassembly work has been increased.
  • the dynamic performance of the flange is improved, the design of which is less susceptible to vibrations, since it is substantially bent in the middle, and conditions are created for long-term operation (increased resource) with minimal wear of the flow part, which also allows to increase operational reliability.
  • the plastic flange contains a central section with a flow hole and a connecting fitting, made integral with the annular peripheral section, on which there are holes for fasteners and radial stiffeners are made located around the central section on one side of the flange, on the other side of which the outer mounting ring and the stop collar are concentrically arranged around a central section made convex and averted with convex from the connecting fitting, the pass of which is connected to a flow hole of the central section.

  • On the other side of the flange there are concentrically arranged an outer mounting ring 14 on an outer edge of the peripheral section 3 and a stop collar 6 around the central section 1.
  • the central section 1 is made convex, for example, of a spherical shape (a hollow sphere segment) or of a convex conical shape (a truncated hollow cone part) and averted with convex from the connecting fitting 7.
  • a pipe manifold or a main pipeline of water supply arrangements is connected to the fitting 7 in conventional manner.
  • the pass of the fitting 7 is connected to the flow hole 2 of the central section 1.
  • the flange is made of glass-filled polypropylene.
  • arcuate stiffeners 8 are made on the peripheral section 3 between the holes 4 for the fasteners. Between each adjacent holes 4 for fasteners one arcuate stiffener 8 and two radial stiffeners 5 are made.

  • the performance of the convex surface of section 1, directed inside the housing 10 during installation, radial and arcuate stiffeners 5 and 8 prevent deformation and the occurrence and transmission of vibrations from pipelines to the housing 10 of the hydraulic accumulator, provide high load-bearing capacity and thereby reduce restrictions on the pressure level in the hydraulic accumulator.
  • the separating elements 15 do not allow the membrane 12 to be pulled outward from the hydraulic accumulator housing 10 and can serve as a central stiffener of the flange.
  • the monolithic plastic flange made of glass-filled polypropylene has such advantages as increased bearing capacity, as well as reliability and durability, lower cost of foundry, stainlessness, lower weight.
  • the present invention is implemented with multipurpose equipment extensively employed by the industry.

Abstract

L'invention concerne une bride en plastique contenant une section centrale (1) dotée d'un trou d'écoulement (2) et d'un raccord de liaison (7), fabriqué d'un seul tenant avec la section périphérique annulaire (3), sur laquelle sont ménagés des trous (4) destinés à des éléments de fixation tandis que des raidisseurs radiaux (5) sont disposés autour de la section centrale (1), sur un côté de la bride. Sur l'autre côté de la bride sont disposés de manière concentrique la bague de montage externe (14), sur le bord externe de la section périphérique (3), et la bague d'arrêt (6), autour de la section centrale (1). La section centrale (1) a une constitution convexe, par exemple sous forme sphérique (segment de sphère creuse) ou sous forme conique convexe (pièce conique creuse tronquée), et opposée à la partie convexe du raccord de liaison (7). Un collecteur de tuyau ou une canalisation principale d'agencements d'alimentation en eau est relié de manière classique au raccord (7). Le passage du raccord (7) est relié au trou d'écoulement (2) de la section centrale (1). La bride est constituée de polypropylène garni de verre. Les raidisseurs arqués (8) sont disposés sur la section périphérique (3), entre les trous (4) destinés aux éléments de fixation. Un raidisseur arqué (8) et deux raidisseurs radiaux (5) sont disposés entre chaque trou adjacent (4) destiné aux éléments de fixation. Des raidisseurs radiaux et arqués (5, 8) sont de différentes hauteurs et sont reliés ensemble au niveau des intersections. La bride en plastique monolithique constituée de polypropylène garni de verre présente des avantages tels qu'une capacité accrue de portée, ainsi qu'une certaine fiabilité et une certaine durabilité, un moindre coût de fonderie, une inoxydabilité et un poids moindre.
