Principle and characteristics of JY41W oxygen stop valve

Y41W oxygen globe valve is designed with anti-static and fire-resistant structure, and all parts are strictly degreased during assembly. The valve body and other components are made of stainless steel and are pickled and passivated. The high-pressure sealing test is carried out with water without any grease for inspection and test, and the leakage test is carried out with 0.6Mpa gas. The valve has no leakage. Working principle: JY41W special oxygen valve is made of silicon brass or stainless steel casting, with high mechanical strength, wear resistance, good safety and so on. Ban oil treatment used in the oxygen pipeline, with explosion-proof flame retardant performance, eliminating the oxygen pipeline unsafe factors.

Stainless steel valve ten common problems

Why does the stainless steel valve double-seat valve oscillate simply when the task is small? For a single core, when the medium is open, the valve has good stability. When the medium is closed, the stability of the valve is poor. The double-seat valve has two valve cores, the lower valve core is closed for flow and the upper valve core is open for flow. In that way, when the valve is in a small opening task, the closed valve core simply causes the valve to vibrate. This is why the double-seat valve cannot be used for small opening tasks.

How to maintain the special stop valve for oxygen

Oxygen cut-off valve grease, often ignore the amount of grease injection problem. After grease injection and oil filling, the operator selects the valve and grease injection connection mode to carry out grease injection operation. There are two situations: on the one hand, the amount of grease injection is insufficient, and the sealing surface is accelerated by the lack of lubricant. On the other hand, excessive grease injection, resulting in waste. It is that there is no accurate calculation of the sealing capacity of different stop valves according to the valve type category. The sealing capacity can be calculated by the size and category of the stop valve, and then a reasonable amount of grease can be injected.
