The elastic soft sealing gate valve features: 1 flat style seat: the traditional valve tube after washing often pass for foreign objects such as stone, wood, cement, paper and other debris deposited on the valve at the end of the groove. Easy to cause can not be closed tightly and the formation of water leakage phenomenon, soft seal gate valve with the same low part of the design of the same water pipes, is not easy to cause debris accumulation, so that fluid without resistance. 2 overall package plastic: valve plate with high quality rubber as a whole, the outsourcing of plastic, the domestic first-class rubber vulcanization vulcanization after the valve plate to ensure accurate geometry, and the rubber and ductile iron gate connection is firm and not easy to fall off and good elastic memory. 3 corrosion resistance: valve body using powder epoxy resin coating, can prevent the body from corrosion and rust, and can be used for sewage system. 4: no fragmentation of traditional cast iron garden gate often hit foreign objects, collision or overlap caused by the fracture phenomenon. This situation has been greatly reduced due to the use of ductile iron in the valve. 5 three "O" ring ring: as the valve stem by three "0" ring ring seal design, can reduce friction when the switch is Water Leakage lightning can significantly reduce the phenomenon of construction of replacement seals off the water. 6 help to drink: due to the internal body with non-toxic epoxy resin coating, the inner and outer surface of the gate are completely coated with rubber without the appearance of rust or corrosion phenomenon, can be used for drinking. 7 Casting valve: valve body casting, precise geometry makes the body without any internal finishing to ensure that the valve seal. 8 light weight: This valve is made of ductile cast, the weight is less than the traditional weight loss of about 20%-30%. Convenient installation and maintenance. The elastic valve seat seal is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The main domestic well-known manufacturers of Hebei Heng valve equipment Co. Ltd. The company is the Ministry of machinery industry, the Ministry of chemical industry, China Chemical Equipment Corporation designated management of production enterprises. Its products in the industry has a certain price advantage and technological advantage.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
弹性软密封闸阀的性能检测:1阀门某一规格批量制造时,应委托权威性机构进行以下性能的检测:①阀门在工压状况下的启闭力矩;②在工压状况下,能保证阀门关闭严密的连续启闭次数:③阀门在管道输水状况下的流阻系数的检测.2阀门在出厂前应进行以下的检测:①阀门在开启状况下,阀体应承受阀门工压值二倍的内压检测;②阀门的关闭状况下,两侧分别承受1.1倍阀门工压值,无渗漏;但金属密封的蝶阀,渗漏值亦不大于相关要求。
