1. Failure of oil tanker The oil seal needs to be replaced in a timely manner. The tanker has a lot of moving parts because of some mistakes in the installation process. Caused the oil seal edge and the oil neck appears misaligned, yaw and throw oil. Some of the oil tanker's oil seals have been used for a long time because the rubber gradually deteriorated and lost its original elasticity. Therefore, when there is an oil spill accident, it must be replaced immediately. 2, the tanker needs to use the liner. The gaskets provided between the parts on the shell, the end face of each interface, the plane lid, and the like on the standing position of the tanker are sealed against leakage. When the gasket is not able to meet the relevant technical requirements in terms of material and process, quality and installation, then the use of the seal to prevent leakage cannot be achieved, if the valve cover of the tanker and the oil pan Because the area it comes in contact with is relatively large, but it is not dense, it will lead to oil spills. 3, tanker vehicles need to maintain a good ventilation valve and one-way valve, to avoid the emergence of blocking the situation. If the two valves have blocked, it will cause the temperature in the enclosure to rise rapidly, and the oil and gas of the tanker will be filled with the entire space and the emissions will not go out, making the tank in The pressure will continue to be deeply loved, which will increase the consumption of lubricating oil, and will lead to a significant reduction in the replacement cycle of the valve. When the tanker's winter through-passage system has become blocked, there will be increased resistance to piston movements, resulting in increased fuel consumption. Because of the pressure of the outside of the car's shell and the effect of the internal pressure, it will lead to oil leakage in places where the sealing is relatively weak. 4. All types of nuts on the tanker need to be tightened according to the relevant regulations. Because the nut is too loose and loose, the liner will leak. However, the time required for attention is too tight, and it will cause the metal around the nut screw hole to appear convex, and there will be a case where oil leakage occurs after the screw is screwed. Industrial butterfly valves are wildly used in all type of industrial pipelines, such as power stataion, petrochemical, oil refinery, natual gas,water treatment ect. Centreline Butterfly Valve, Double Offset Butterfly Valve, triple offset butterflyvalve, Cw Butterfly Valve large diameter Butterfly Valve and Rubber Lined Butterfly Valve with ASME & DIN standard are commonly used by customer. Industrial butterfly valve we provided are with soft and metal seal type and valve size are from 12 inch to 120 inch(DN300-DN3000) matching pressure from class 150 to class 2500(PN10-PN420) which are suitable for operating in the working media temperature from -29℃ to 593℃, as well as material in Cast iron, ductile cast iron, carbon steel, stainless steel, alloy steel and duplex steel in casting material.
