The opening and closing parts of the liquefied air valve are plug -shaped valve petals. The cover surface is plane or cone surface, and the valve petals are mounted straight along the central line of the fluid.The movement of the valve stem has a lifting rod type (the valve stem lifting, the hand wheel does not rise), and the lifting rotation rod type (the hand wheel and the valve stem are rotated together, the nut is set on the valve body).The tube cuttering valve is only suitable for full -opening and full levels, and is not allowed to regulate and save.
LNG Valve leakage
Bar off the valve, then take the wrench handle first, and then unscrew the first nut to see the skin ring inside. Just hit it and change it.If there is no leather ring, you can find the raw material belt for connecting tap water, wrap a few more circles clockwise and then re -put the nut. If it is a liquefied gas tank, it cannot be repaired.Essence

How to use liquefied air valves
One: You must clean the inner cavity of the dedicated valve before installing the valve, and clear the defects produced during transportation to avoid the impact of these defects on the normal work of the valve.Two: Install the liquefied air valve in a place that is easy to repair and install it on a horizontal pipeline.Three: When installing the liquefied air valve, first open the channel tube rice next to it to discharge the condensed water and other mixtures in the tube.Fourth: The liquefied air valve is a sealing valve. Therefore, when we close the valve, we must want to apply a certain pressure at the valve petals. The pressure is to force the seal to prevent it from leaking.When the gas enters the valve, the force of the valve stem and the gas friction and the thrust generated by the medium in the valve are the resistance that the gas needs to overcome, so the diameter of the valve is large enough.
