Abstract
The present invention relates to a metal tube circular moulded sealing washer and a manufacturing method thereof. The metal tube circular moulded sealing washer comprises a circular metal tube and flexible seal filling materials, wherein the flexible seal filling materials are filled in the metal tube; cladding layers are respectively arranged at the upper and the lower surfaces of the metal tube which is clamped between a limited inner ring and a limited outer ring. The manufacturing method of the metal tube circular moulded sealing washer comprises the following steps: 1) the flexible seal filling materials are filled in an inner cavity of the metal tube; 2) the metal tube is bent into a circular shape; 3) nozzles at two ends of the circular metal tube are firmly welded in a butt way, and a sealing ring is formed; 4) the metal tube is shaped by moulding, and the metal tube is tightly clamped between the limited inner ring and the limited outer ring; 5) the upper and the lower surfaces of the metal tube are respectively covered with the cladding layers. The compression and the rebound degree of the metal tube circular moulded sealing washer can be adjusted by controlling the density of the filling materials; meanwhile, the inner and the outer rings, and the cladding layers are added, so the mechanical properties of the sealing washer can be enhanced, the amount of the compression and the properties of the rebound can be enhanced; particularly, the thermal shock resistance and the fatigue performance are effectively enhanced. The present invention has the advantages of wide range for bearing stress, and convenient installation and use.
Description
Technical field
The present invention relates to a kind of manufacture method of gasket seal, particularly relate to a kind of manufacture method of metal tube circular moulded sealing washer.
Background technique
In the prior art, gasket seal is many to be made with flexible material, for example asbestos, rubber etc., because the ability that this kind material meets with stresses is relatively poor, in use for some time, owing to bear the effect of pressure and ambient temperature, gasket seal is easily aging or lax, sealing variation even lose sealability, flexible when mounted distortion has simultaneously influenced sealing effect.The gasket seal that other has metallic material to make, because of metal tube is a hollow, resistance to pressure and compression recovery performance are limited, Applicable scope is narrower, do on this basis with improved metallic packing, the metal tube of hollow is provided with opening, though play the effect of self-tightening sealing, but explosion easily takes place when using and by problems such as medium obstructions, do not reach desirable sealing effect.
Summary of the invention
The object of the invention provides a kind of manufacture method of metal tube circular moulded sealing washer, and the gasket seal of this method manufacturing has stronger mechanical property and is convenient to install and use.
Technological scheme of the present invention is: a kind of manufacture method of metal tube circular moulded sealing washer, and 1. it comprise the steps:, described flexible sealing packing inserted in the inner chamber of metal tube; 2., the metal tube that will be filled with the flexible sealing packing bends to annular; 3., the two ends mouth of pipe butt joint of the metal tube of ring-type is welded, form sealed pipe; 4., by compression molding, the metal tube chucking that 3. step is made ring and limiting between the outer shroud in restriction; 5., the described upper and lower surface that has the metal tube that limits inside and outside ring is covered coating respectively.
Described step 1. in, the stuffing pressure scope when the flexible sealing packing being inserted in the inner chamber of metal tube is 1 to 20Mpa.
Described step 1. in, the density range of described flexible sealing packing is 1.0 to 2.5g/cm
3
Described step 1. after, the described body that is filled with the metal tube of flexible sealing packing is blocked by needed length, enters described step more 2..
Described step 4. in, the pressure range of mold pressing is 10 to 100Mpa.
Described step 4. in, the pressure preferable range of mold pressing is 40 to 50Mpa.
Described step 4. in, the metal tube flattening that is molded forms the following outer surface of a flat last outer surface peace, it is described that to go up outer surface parallel with following outer surface.
The present invention compared with prior art has the following advantages: this method adopts and will insert the flexible sealing packing in the metal tube, by control packing density, realization is to the adjustment of Sealing compression, rebound degree, also be provided with inside and outside ring and coating simultaneously, the mechanical property of utilizing the gasket seal that this method makes is strengthened and the decrement increase, it is wider to meet with stresses, easy to install.
Description of drawings
Accompanying drawing 1 is a plan view of the present invention;
Accompanying drawing 2 is the A-A direction sectional view of accompanying drawing 1;
Wherein, 1, ring 5, restriction outer shroud in metal tube 2, flexible sealing packing 3, coating 4, the restriction; 6, outer surface on the metal tube; 7, outer surface on outer surface 8, the coating under the metal tube; 9, outer surface under the coating.
Embodiment
Referring to accompanying drawing 1 to the metal tube circular moulded sealing washer shown in the accompanying drawing 2, it comprise ring-type metal tube 1, be filled in the flexible sealing packing 2 in the described metal tube 1, the outer surface up and down of described metal tube 1 is respectively arranged with coating 3, there is the interior ring 4 of the restriction of ring-type the inboard of described metal tube 1, the restricted outer shroud 5 in the outside of described metal tube 1, described metal tube 1 is clamped in the described restriction between the ring 4 and restriction outer shroud 5, and ring 4 and restriction outer shroud 5 be setting with one heart in described metal tube 1, the restriction.Materials such as metal tube 1 usefulness carbon steel, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), titanium are made, described flexible sealing packing 2 is nonmetallic material, as one or more the mixture in graphite, fiber, the teflon, described coating 3 is one or more the composite in graphite, fiber, the teflon, and ring 4 and restriction outer shroud 5 are a kind of in carbon steel, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), the titanium in the restriction.
The wall thickness range of metal tube 1 is 0.1 to 3 millimeter, preferred wall thickness range is 0.3 to 0.5 millimeter, the outer tube diameter scope of metal tube 1 is 2 to 50 millimeters, preferred outer tube diameter scope is 4 to 25 millimeters, metal tube 1 has outer surface 7 under the metal tube of outer surface 6 peace on the flat metal tube, outer surface 6 is parallel with outer surface 7 under the metal tube on the metal tube, as shown in Figure 2.
