[Three rain valve to recommend the star product - Mechanical seal] Description: hollow metal O-ring: good elasticity, compression force is small, there are self-tightening effect, can choose a variety of metal materials, resulting in low temperature, high temperature and strong corrosive media can adapt. Graphite plate ring: in people's minds, graphite is a brittle material, lack of flexibility and toughness, but after graphite special treatment, but it is soft H7N-40 mechanical seal, good elasticity. Thus, heat resistance and chemical stability of graphite, they can be displayed in the gasket material; and this gasket pressing force is small, a very favorable sealing effect. This can be made with graphite, with metal band with H7N-48 mechanical seal, consisting of high performance wound gaskets. Graphite sheet gaskets and spiral wound gasket graphite ---- The emergence of high-temperature corrosion-resistant sealing a major breakthrough. Such gasket seal H7N-55 aircraft, has a large number of overseas production and use [three rain valve to recommend star products - mechanical seals] Introduction: Mechanical seal according to the working conditions and the different nature of the medium, there is high temperature, low temperature mechanical seals, high pressure, corrosion-resistant mechanical seals, mechanical seals and resistant granular media adapt easily vaporized light hydrocarbon medium mechanical seal mechanical seal, mechanical seal should choose a different type of construction and materials depending on the use. Mechanical seals are widely used in all sectors of business. Water pump plant, printing machinery, paper mills, power plants, chemical plants, pharmaceutical shipyard, and sewage treatment plants, and is widely used in hospitals, agriculture, cooling equipment category, the tanning industry, heavy machinery. H7N-53 mechanical seal, mechanical seal guest, H7N mechanical seal provided by the election of three rain Valve Co., Ltd. Tianjin three rain. Valve Co., Ltd. Tianjin three rain (www.tjsymf.com) strong, credible, in Tianjin seal industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the three rain valve into the brilliant and you work for a better future!
