Pipeline Transmission Joint, Serco supply material (certified), power transmission connectors are provided by Serco Gongyi City Water Supply Materials Co., Serco Gongyi City Water Supply Materials Co., Ltd. (www.gyxjbcq.com/) is specialized in the "PTFE lined rubber joints, standard waterproof casing, duckbill valve, power connector, stainless steel rubber joints" of the enterprise, the company adhering to the "integrity business, hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Zhang. When installing a check valve, special attention should be medium flow direction, the media should be consistent with the direction of the normal flow direction indicated by the arrow on the valve body, otherwise it will cut off the normal flow of the medium. Bottom valve should be installed in the bottom of the pump suction piping. When the valve closed joint-force manufacturers will produce water hammer pressure in the pipeline, can cause serious damage to the valves, piping or equipment, especially for large mouth lines or high-pressure line, it should lead to the selection valve those close attention. Serco duckbill valve production materials mainly include neoprene, nitrile rubber, fluorine rubber. Flexible rubber structure, not deformed or freeze when you turn on and off. Will not rust or corrode double Falan Song sets of power transmission connectors, avoid backflow device. Wing plus a full rubber duckbill valve structure in shape "duckbill", with "forward into the reverse backstop" a new drainage valve product features. It is calculated based on stress analysis and stress for different conditions, different design mechanisms, use of different rubber formulations made in accordance with a special process. When forward, imported water from flowing into the power transmission connectors, tiny water pressure, will be able to open the valve, the greater the pressure, the valve opens, the greater the water flow. Reverse work naturally closed valve, double flanged pipe sealing backstop power transmission connectors, the greater the backpressure valve more tightly, sealing the better. It is widely used in a variety of municipal effluent outfall, water, sewage treatment, etc., to prevent intrusion, back, is the ideal product to replace shoot the door.
