| titleOfInvention | Accumulator using 3-layer diaphragm |
| abstract | This invention relates to the improvement of the diaphragm for accumulators.n n n Although the center part of the diaphragm in which the poppet is provided rises at an obliquely tilted state, the position of the bending deformation | transformation part M in a diaphragm often shifts in the direction toward an outer side from a center part side, In this way, a bending deformation part If the position of (M) is displaced in the direction from the center side to the outside, the stress is concentrated at this point, so that the diaphragm cracks and causes damage, and the accumulator life is significantly shortened. there was. In addition, in the conventional accumulator diaphragm having a resin layer in order to suppress gas permeability, the surface of the gas chamber and the surface of the inflow chamber are formed of a rubber layer, and are often composed of five or more layers including both rubber layers. In addition, the production cost is high, the consumer price is high, and manufacturing is difficult. On the other hand, the three-layer diaphragm including both rubber layers has a problem that gas is not completely blocked when gas is used, and gas is permeated.n n n The present invention is to solve the above-mentioned conventional problems, to ensure that the diaphragm of the three-layer structure to be stably deformed on the central axis when the working pressure fluctuates, to prevent damage to the diaphragm, and to suppress the gas permeability of the diaphragm It is an object of the present invention to provide an accumulator which can be made easy, is easy to manufacture, has a low manufacturing cost, has high processing efficiency at the time of manufacture, and has a remarkably long life.n n n The accumulator of the present invention is 49 to 55 wt% silicone rubber, 11 to 14 wt% ethylene vinyl acetate polymer, 8 to 10 wt% adipic acid ester, 8 to 10 wt% zinc oxide, 2 to 5 wt% polyolefin resin, plasticizer 3 to 4 wt% of antioxidant, 2 to 4 wt% of antioxidant, 1 to 3 wt% of stabilizer, 5 to 6 wt% of vulcanizing agent and vulcanization accelerator, gas chamber side rubber layer 83, and vinyl chloride resin 36 to 43 wt% , 11-16 wt% acrylic acid ester, 6-10 wt% ethylene propylene copolymer, 7-12 wt% acrylonitrile, 6-9 wt% plasticizer, 10-15 wt% polyolefin resin, 8-12 wt% calcium carbonate 19-25 wt% of ethylene butadiene copolymer rubber, 18-21 wt% of polyvinyl chloride thermoplastic elastomer, 10-12 wt% of polycarbonate polyol, 10-16 wt% of ethyl acetate, between the single-layer resin layer 82, 10-15 wt% polyamide resin, 10-12 wt% pimeric acid, 6-9 wt% ethyleneamine, petroleum based Applying the gas chamber side adhesive of the composition of 3-6 wt%, the resin layer 82 which is said single layer, 34-38 wt% of natural rubber, 29-31 wt% of organic peroxide, 25-29 wt% of polyvinyl chloride, poly 0.9 to 2.2 wt% of oxyalkyrene monofatty acid ester, 0.6 to 1.4 wt% of polyethylene glycol, 1.0 to 1.6 wt% of zinc oxide, 0.7 to 1.5 wt% of snorte, 0.3 to 0.7 wt% of antioxidant, 0.3 to 0.6 wt of vulcanization accelerator %, 31 to 38 wt% urethane prepolymer, 14 to 18 wt% ketone resin, between the oil-based rubber layer 81 which is a single layer composed of 0.4 to 0.8 wt% vulcanizing agent and 0.4 to 0.6 wt% retardant. Apply oil-based adhesive consisting of 9-14 wt% of styrene, 10-13 wt% of triethylene glycol, 8-13 wt% of isopropyl alcohol, 7-11 wt% of plastic epoxy resin, and 5-9 wt% of isophthalic acid, and then press By adhering, and placing the gas chamber side rubber layer 83 on the nitrogen gas chamber 87 side, and the oil chamber side rubber The gas chamber side protrusion 95 of the diaphragm is provided on the gas chamber side of the diaphragm 85 having such a three-layer structure, and 81 is provided on the oil chamber 88 side, and the oil chamber side of the diaphragm 85 is provided. With the oil chamber side projection 96 of the diaphragm, the gas chamber side rubber layer thickness T1 of the diaphragm is in the range of 1/5 to 3/5 times the total thickness T of the diaphragm in which the resin layer and the rubber layer are combined. The oil measurement rubber layer thickness (T2) is in the range of 2/5 to 3/5 times the total thickness (T) of the diaphragm in which the resin layer and the rubber layer are combined, and the resin layer thickness (T3) is the sum of the resin layer and the rubber layer. The diaphragm has a thickness of 1/6 to 2/5 times the total thickness T, and the diaphragm gas projection side width t1 is 2 to 5 times the total diaphragm thickness T. The oil side projection width t2 of the diaphragm is in the range of 2 to 5 times the total thickness T of the diaphragm, and the distance f1 between the gas chamber side projections of the diaphragm is diaphragm. The range of 5 to 14 times the total thickness T, the distance f2 between the oil chamber projections is 5 to 14 times the total thickness T of the diaphragm, and the height of the gas chamber protrusion of the diaphragm. (h1) is in the range of 2 to 4 times the total thickness (T) of the diaphragm, and the oil-side projection height (h2) of the diaphragm is in the range of 2 to 4 times the total thickness (T) of the diaphragm. .n n n The accumulator of the present invention allows the diaphragm to be stably deformed on the central axis when the working pressure fluctuates, thereby preventing damage to the diaphragm, suppressing the gas permeability of the diaphragm, and is easy to manufacture. It is inexpensive, the processing efficiency at the time of manufacture is high, and the accumulator has a long life.n n n n Accumulator, Diaphragm, Rubber, Resin, Gas, Oil |
