高压焊接球阀
高压焊接球阀产品特点
1.高压焊接球阀所有部件均为锻件
2.采用下装式阀杆,设置倒密封结构,确保填料处可靠密封及防止阀杆脱出。
3.采用镶嵌式阀座。阀座背后设置O型圈,确保介质不外漏。
Features
1.All the components are forged ones.
2.Lower-loading Stem and backward sealing construction have been setup for positive sealing at stuffing position and backing-out protecting of the handle.
3.Interbedded valve seat is applied on whose bace RO-ring is also mounted for avoiding the leakage of medium.
