进口燃气放散球阀，埋地式安全双放散球阀性能描述 Performance description

燃气放散球阀（埋地式安全双放散球阀）可根据管道的施工及设计要求，调整阀体的长短和阀杆的高度。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，只需在地面上进行传动操作即可  RETZ The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline. All welded directly buried ball valve can be directly buried underground. No underground valve control room is required (as shown in the figure), so the operator does not need to go deep into the ground, and only needs to drive on the ground

进口燃气放散球阀，埋地式安全双放散球阀产品特性 Product characteristics

1、带放散装置，开关灵活，力矩小 With release device, flexible switch and small torque

2、整体焊接而成，不会有外部泄漏等现象 It is welded as a whole without external leakage

3、由管材构成，强度足够，价格低廉，外形美观，施工方便 It is composed of pipes with sufficient strength, low price, beautiful appearance and convenient construction

4、当阀门处于全开或全关位时，可打开排放塞。当打开排放塞时，请准备一个扳手用以防止排放塞突然脱离。可利用关断和排放功能检验阀门的密封完整性。如果阀门的一端排放不能停止即表明阀座可能已泄露 When the valve is in the fully open or fully closed position, the drain plug can be opened. When opening the drain plug, please prepare a wrench to prevent the drain plug from suddenly leaving. The sealing integrity of the valve can be checked using the shut-off and discharge functions. If the discharge at one end of the valve cannot be stopped, the valve seat may have leaked

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
