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

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（如图），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 buried all welded ball valve (buried all welded sealed ball valve) All welded directly buried ball valve can be directly buried underground. There is no need to set up an underground valve control room (as shown in the figure), so the operator does not need to go deep into the ground, but only needs to use a T-shaped handle to drive on the ground, which is very convenient, and avoids the potential safety hazard caused by setting up an underground valve control room in 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 The processing of the sphere is tracked and detected by an advanced computer detector, 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 As the valve body material is the same as the pipe material, there will be no uneven stress, no deformation due to earthquake and vehicles passing the ground, 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 ring body 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 The processing 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 balls and springs are installed between the valve rod and the ball as well as between the valve rod and the stuffing box, which can keep all parts of the valve conductive to the valve body and let the current pass through the area to release static electricity
