Description

The sealing ring being tightly connected for pipe fitting
Technical field
The present invention relates to neodymium iron boron production equipment technology, specifically, it is related to and a kind of is tightly connected for pipe fitting Sealing ring.
Background technology
Neodymium-iron-boron magnetic material, as rare earth permanent-magnetic material development latest result, due to its excellent magnetic property by Referred to as " magnetic king ".Neodymium-iron-boron magnetic material is the alloy of praseodymium neodymium metal, ferro-boron etc., also known as magnet steel.Neodymium iron boron has high magnetic Energy product, coercivity and energy density, it is applied widely in modern industry and electronic technology, makes instrument and meter, electricity Miniaturization, lightweight, the slimming of the equipment such as acoustic-electric machine, magnetic separation magnetization are possibly realized.
Contain substantial amounts of rear earth element nd, iron and boron in neodymium iron boron, its characteristic is hard and crisp.The advantages of neodymium iron boron is cost performance Height, has good mechanical property;Be disadvantageous in that operating temperature is low, temperature characterisitic is poor, and be easy to dusting corrosion and easily by Oxidation.
In existing neodymium iron boron manufacturing process, it usually needs using charging basket to being exported from airflow milling discharge outlet NdFeB magnetic powder carries out splicing, storing.More conventional charging basket is typically made up of a cylindrical shape staving at present, is set on the charging basket There is the material receiving port to match with the discharging opening of airflow milling, although it more convenient can carry out splicing to neodymium iron boron, due to neodymium Iron boron easily aoxidizes in itself, and such barrel to air can not completely cut off while splicing, so as to cause neodymium iron boron The very big reduction of quality.
Cause having its source in for above mentioned problem:During lacking one kind in the prior art specifically for such as neodymium iron boron splicing The barrel used, and lack and a kind of can still possess the close of preferable sealing property during quick, multiple demolition, installation Envelope mechanism.
The content of the invention
In order to overcome certain or some defects of prior art, the invention provides a kind of vapour-pressure type gasket seal.
According to the vapour-pressure type gasket seal of the present invention, it includes the outer rubber circle being arranged concentrically and interior rubber ring, outer rubber Circle and interior rubber ring are connected as one by least two connecting tubes being uniformly distributed circumferentially;Outer rubber circle inner hollow constructs Into the air storing cavity of annular shape, interior rubber ring inner hollow is configured to the air collecting chamber of annular shape, is configured with the middle part of any connecting tube For connecting the gas flow of air storing cavity and air collecting chamber.
