A soft valve is a flexible valve used to connect hardware piping. The product has the characteristics of impact resistance, noise reduction and displacement resistance. At the same time, due to the special structure of the product, it also has the characteristics of waterproof and leak proof. The sealing principle of the valve should start from the product structure!
The valve is composed of inner layer, nylon cord, outer ball and loose metal flange. Through the introduction of advanced production technology from abroad, the inner layer is in a high-pressure state, which makes the nylon cord fabric and layer better combined than ordinary flexible valves, with higher working pressure and better quality. It is characterized by the mixing of inner layers, smooth and seamless marking, label vulcanization, and integration with products.
The main materials of the inner layer of the valve are natural and styrene butadiene, or natural, styrene butadiene and cis-1,4-polybutadiene; You can also use a mixture with plastic, and you can use an appropriate amount of regeneration. Vulcanization systems usually use sulfur and accelerators in traditional vulcanization systems. The amount of sulfur is 1.5-2.5, and thiazole and sulpheneamide are better for promoters. Reinforcement and filling system: high wear-resistant carbon black, semi reinforced carbon black mixed with general carbon black, usually with better comprehensive performance. Softener: petroleum softener, such as heavy oil, loose tar and solid softener, such as asphalt, petroleum tree. The effect is better when fat is used together.
The valve mainly utilizes unique properties, such as high elasticity, high air tightness, medium resistance and radiation resistance. The polyester cord with high strength, strong thermal stability and cold stability is molded, pressed and cross-linked under high pressure and high temperature. It has high internal density, high pressure and excellent elastic deformation effect. The product structure design has high-end arc, long curve and large displacement functions. It is especially suitable for places with complex geological conditions, large settlement range, and frequent changes in cold and heat that cause pipeline damage. The physical displacement of the pump effectively eliminates the valves and pipes through the heat transfer and escape functions of the elastic sliding displacement and deformation mechanical force. As a poor conductive material, it is also an ideal environmental protection product to reduce vibration and noise transmission. The inner wall of the product is smooth. Through actual tests, it has no impact on the speed and flow rate of the medium, never rusts, and can basically avoid lifelong maintenance.
