Oil Tank Pedal Gauge hatch

There are Two Types Gauge Hatchs:

TYPE ONE--Rotary Gauge hatch

Rotary Gauge hatch is a special accessory used to measure the oil level in the tank and to pick up the oil sample. One of the tops of each tank is located, mostly located near the tank platform. The fire in the oil tank often occurs in the measuring hole. The main reason is that when the measuring operation, the hole cover opens the oil and gas in the tank, and if the static spark or the impact friction sparks, the fuel gas will catch fire.

TYPE TWO--Pedal Gauge hatch

Pedal Gauge hatch is installed on the top of the oil tank to measure the elevation and temperature of the oil in the tank and the sampling. The chemical materials have different degrees of harmful odor and cannot be discharged into the atmosphere during measurement. In order to complete the measurement procedure and ensure that the environment is not affected and the operator is safe to operate, the oil hole can play a role in this.

Structural features and working principle:

The (4 inch / 6 inch) Gauge hatch is mainly composed of a valve body, a rotary latch, a tensile kidney, a sealing cover, a rolling bolt, and a hand wheel.

The Gauge hatch is used to ensure the measurement error every time the oil is cut along the same position, and the aluminum or copper guide groove is installed on one side of the inner wall of the oil hole. There should be no welds on the bottom of the tank below the oil hole. If necessary, a gauge plate can be welded there to reduce the relative error of each measurement. The measuring hole has a diameter of 100 mm and is provided with a closed hole cover and a loose bolt. In order to prevent the hole cover from colliding with the iron to generate spark when closing, an oil-resistant rubber pad or soft metal (copper or aluminum) is embedded in the sealing groove of the hole cover. ). Since the steel tape measure for measuring is easy to rub and generate sparks, a copper (or aluminum alloy) sleeve is placed inside the hole tube, or a non-ferrous metal guide groove (a measuring groove) which does not generate sparks is installed outside the fixed measuring point. . The oil hole is often opened and closed, and it is easy to be damaged and leaks. Therefore, the tightness should be regularly verified. During the identification, apply a thin layer of paint on the edge of the hole, gently cover the hole cover, and add a certain force by hand. If the village pad has obvious traces, it can be considered qualified. If the trace is incomplete, the hole cover is not tight and the gasket should be replaced.
