　　进口直埋式全焊接球阀 埋地式全焊封球阀性能描述 performancedeion

　　直埋式全焊接球阀（埋地式全焊封球阀）全焊接直埋球阀，可以直接深埋地下。不用设置地下阀门控制室，这样操作者不需要深入地下，只需在地上用t型手柄进行传动操作即可，非常方便，避免了以往由于设置地下阀门控制室而存在的不安全隐患retz品牌 directly buriedall welded ball valve (buried all welded sealed ball valve) all welded directlyburied ball valve can be directly buried underground. there is no need to setup an underground valve control room (as shown in the figure), so the operatordoes not need to go deep into the ground, but only needs to use a t-shapedhandle to drive on the ground, which is very convenient, and avoids thepotential safety hazard caused by setting up an underground valve control roomin the past

　　进口直埋式全焊接球阀 埋地式全焊封球阀产品特性 product characteristics

　　球体的加工过程有先进的计算机检测仪跟踪检测，所以球体的加工精度高 theprocessing of the sphere is tracked and detected by an advanced computerdetector, so the processing accuracy of the sphere is high

　　由于阀体材料跟管道材质一样，不会出现应力不均，也不会由于地震及车辆经过地面时而产生变形，管道耐老化 asthe valve body material is the same as the pipe material, there will be nouneven stress, no deformation due to earthquake and vehicles passing theground, and the pipe is aging resistant

　　密封环本体采用含量20%carbon（碳素）的rptfe材质，保障完全无泄漏 the seal ringbody is made of rptfe material containing 20% carbon to ensure no leakage

　　球体的加工精度非常精密，操作轻便，无不良干涉 theprocessing accuracy of the sphere is very precise, the operation is convenient,and there is no adverse interference

　　防止静电，阀杆与球体以及阀杆与填料箱之间分别装有钢球和弹簧，可以保持阀门所有零件与阀体的导电，让电流通过区，释放静电 to prevent static electricity, steel ballsand springs are installed between the valve rod and the ball as well as betweenthe valve rod and the stuffing box, which can keep all parts of the valveconductive to the valve body and let the current pass through the area to releasestatic electricity
