Locking Type Sealing Device

详情

This is a new sealing device for oil loading on top, On the premise of no changing the tank mouth, the sealing problem of crane pipe with oil and gas recovery is solved.Can realize one-step operation (one step can be locked, one step can be released);Equipped with a protective level alarm probe (proprietary built-in, anti-impact);The cylinder is specially made with proprietary technology.The rubber pad is specially made.Can be against benzene, xylene resistance, gasoline resistance, corrosion resistance, anti-static;It has 6 patents and 2 proprietary technologies.

After testing, the leakage detection value of domestic sealed crane pipe when loading is low limit of 3.***7% V (hydrocarbon, gasoline explosion range of 1.**7.6% V).

For the locking seal device of manual automobile, the lowest leakage detection value of crane pipe is 0.0%V (hydrocarbon), and the average value is 0.*5%V (hydrocarbon).

The leakage detection value of the third party pneumatic locking sealing device for

tank truck loading is 0.**6%V (*0ppm) , which is far lower than the 0.*5%V leakage value stipulated by the state.

The lowest leakage detection value of the third party of pneumatic locking sealing device for train loading is 0.**8%V (*0ppm), also which is far lower than the national leakage value of 0.*5%V, and which is more than one percent of similar sealing devices (*3 times higher than that of similar devices *- **2 times higher).
