Description

Hydraulic control pipe through-piece of remote control valve

Technical field

Background technique

The traditional design pattern of the oil-water-tight fittings used in the traditional product oil and crude oil cargo tank remote control valve hydraulic control pipe on the deck surface is the welding of the body and the hull deck using the stainless steel sleeve as the penetration piece, and the control tube passes through the sleeve. After that, the wrapped Teflon packing is filled between the sleeve and the control tube for sealing, and finally the pressing part is pressed on the top of the body of the through piece.

During installation, the Teflon packing needs to be wound around the outer wall of the control tube one turn or another. When the control tube is inserted into the body, the packing is clamped between the outer wall of the control tube and the through body. The 8x8mm packing calculation, if the through body height is 100mm, the number of windings required to be wound is nearly 12 layers. Since it is difficult to prevent the existence of the gap between each layer of the packing, and since the wound Teflon packing itself is also woven by winding, there is a gap in itself. Therefore, the sealing type adopted by the conventional through-piece is extremely likely to cause leakage, that is, rainwater or seawater on the deck surface is likely to leak into the cargo compartment, resulting in contamination of the goods.
