進口直埋式全焊接球閥，埋地式全焊封球閥性能描述 Performance description

直埋式全焊接球閥（埋地式全焊封球閥）全焊接直埋球閥，可以直接深埋地下。不用設置地下閥門控制室（如圖），這樣操作者不需要深入地下，只需在地上用T型手柄進行傳動操作即可，非常方便，避免了以往由于設置地下閥門控制室而存在的不安全隱患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

進口直埋式全焊接球閥，埋地式全焊封球閥產品特性 Product characteristics

球體的加工過程有先進的計算機檢測儀跟蹤檢測，所以球體的加工精度高 The processing of the sphere is tracked and detected by an advanced computer detector, so the processing accuracy of the sphere is high

由于閥體材料跟管道材質一樣，不會出現應力不均，也不會由于地震及車輛經過地面時而產生變形，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

密封環本體采用含量20%Carbon（碳素）的RPTFE材質，保障完全無泄漏 The seal ring body is made of RPTFE material containing 20% Carbon to ensure no leakage

球體的加工精度非常精密，操作輕便，無不良干涉 The processing accuracy of the sphere is very precise, the operation is convenient, and there is no adverse interference

防止靜電，閥桿與球體以及閥桿與填料箱之間分別裝有鋼球和彈簧，可以保持閥門所有零件與閥體的導電，讓電流通過區，釋放靜電  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
