摘要
通过改进原有压力表接头,设计出一种截至式压力表接头,该接头在实际应用中卸掉压力表时能瞬间封闭管线中油气液向外刺漏,提高管线安全性。
Pressure joints by improving the original design of a type pressure gauge as at joints, the joints in practical applications can be instantly removed when the pressure gauge closed Petroleum gas pipeline leak out thorns and improve pipeline safety.
