Description

Pipe end limiting device and using method thereof

Technical Field

The invention relates to the technical field of ship construction, in particular to a pipe end limiting device and a using method thereof.

Background

On ships, tanks are generally provided with liquid level meters for measuring liquid levels, and the adopted liquid level meters have two types of side mounting and top mounting. Because boats and ships are when navigating, under the effect of billow, can take place anomalous rocking, the liquid in the cabinet will constantly rock, under the promotion of liquid, top installation formula liquid level can receive the effect of periodic thrust, for preventing that top installation level gauge from being destroyed, general top installation formula level gauge can be equipped with protective sleeve, and according to the requirement, protective sleeve needs to be fixed in the cabinet, and when liquid rocked, protective sleeve can not rock.

When the liquid level meter is fixed, both ends of the liquid level meter are required to be fixed in order to achieve the expected effect. The outside of the cabinet is generally in flange connection, and the liquid level meter can be periodically overhauled, so that the end part of the protective sleeve in the cabinet cannot be directly fixed on the angle steel bracket by the U-shaped pipe clamp like a common pipe, the protective sleeve is not easy to take out, and the protective sleeve is difficult to put back into the original U-shaped pipe clamp after being taken out, and the operation cost is too high unless people enter the cabinet for installation.
