About Leakage of Metal Seat For Knife Gate Valve

Posted on 2023年9月19日2023年10月24日 by Lixin

Our metal seated Knife Gate Valve is made as per the specification of MSS SP-81.As we see, the article 10.2 of this standard specified the leakage rate of this valve,that means the valve’s seal leakage is allowable.

Through all the international manufacture designs of metal seated knife gate valve,disc seal need very big pressure ratio,but actually the seal can only offer little pressure ratio because the structure design,it too hard to fulfill,so caused seal leakage.

If the medium is dry ash,paper slurry,particle calcium carbide etc. self-seal flow.From the view of physics,the water molecules’ diameter is far smaller than dry ash and other composition of the flow.It’s more easier to across the micro tunnel of seal face,cause leakage.But the self-seal medium will jam the micro leakage tunnel automaticly under the pressure when the valve is closed,and this can reach the leakage rate of the national standard,and fulfill clients’ application.

So,we do not do seal tests,and shell hydraulic test only.

PTFE Packing Leakage Reason

Posted on 2023年9月19日2023年10月24日 by Lixin

Before delivery LIIXN made test for all the valves,and why it also have leakage?

We presume that:

1. When the valve is make pressure test, there will be force to cause the packing to expand, and after the test, the external force is lost, which may cause the bolt to be a little loose

2. The valve needs to be ultrasonically cleaned before leaving the factory, so that the dirt and oil on the surface of the valve can be removed, but when it is cleaned by ultrasonically, it will vibrate and cause the bolts to become loose.

Lift Type Plug Valve Working Process

Posted on 2023年9月19日2023年10月24日 by Lixin

Process of opening and closing of the valve. When open the valve, firstly turn the handwheel to make the plug lifted and separated with the sealed surface, then turn the handle by 90 degree to connect the channel of plug with the channel of valve body. So that the valve is opened. When close the valve, firstly turn the handle by 90 degree to make the channel of plug vertical to the channel of the valve body, then the handwheel to descend the plug, so that the valve is closed.
