DQS-25P型低溫三通球閥
DQS-25P型低溫三通球閥 DQS - 25 p type three-way ball valve at low temperature
此類型是"T"型通道三通球閥主要用于組合安全系統閥的安全閥及防爆膜片的安裝主體。除能大大地減化和優化貯槽管路、減少貯槽組裝時間和二組安全附件同時工作的特點，并且更換安全閥方便、可靠。廣泛用于液氧、液氮、液態乙烯及其它低溫介質，具有密封可靠的特點。
This type is the ""T"" type channel of the 3-way ball valve is mainly used in integrated security system valve relief valve and the installation of the explosion-proof membrane. In addition to can greatly simplify and optimize pipeline of storage tank, storage tank assembly time and the characteristics of two groups safety accessories work at the same time, and replace the relief valve is convenient and reliable. Widely used in liquid oxygen, liquid nitrogen, liquid ethylene and other low temperature medium, has the characteristics of the sealing is reliable.
