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

　　燃气放散球阀应用在天然气管道的专用型产品，是由双放散管加直埋式全焊接球阀组成，放散管与直埋杆根据客户要求制造，双放散管在阀杆左右侧各一个，在管道维修或者维护时通过双放散管可以把多余的介质放出，降低压力，保护管路安全thegas vent ball valve is a specialized product used in natural gas pipelines. itis composed of a double vent pipe and a directly buried fully welded ballvalve. the vent pipe and the directly buried rod are manufactured according tocustomer requirements. the double vent pipe is located on the left and rightsides of the valve rod, and during pipeline repair or maintenance, excessmedium can be discharged through the double vent pipe to reduce pressure andprotect pipeline safety

　　进口燃气放散球阀 埋地式排气球阀产品特性 productcharacteristics

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

　　2、整体焊接而成，不会有外部泄漏等现象 it iswelded 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 iscomposed of pipes with sufficient strength, low price, beautiful appearance andconvenient 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 whenthe valve is in the fully open or fully closed position, the drain plug can beopened. when opening the drain plug, please prepare a wrench to prevent thedrain plug from suddenly leaving. the sealing integrity of the valve can bechecked using the shut-off and discharge functions. if the discharge at one endof the valve cannot be stopped, the valve seat may have leaked

　　5.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 torelease static electricity
