Description

FIELD OF THE INVENTION [0001] The present invention relates to a pipe fitting,

The present invention relates to an apparatus for protecting a fitting of a pipe, and more particularly, to a pipe fitting for protecting a fitting of a pipe, in which fittings provided on pipes such as gas and fluid are selectively used, The present invention relates to an apparatus for protecting a fitting of a pipe.

Generally, a fitting such as a bolt / nut fastening structure or a valve is provided on a pipe of various pipes for transferring gas, liquid, etc., for example, to connect and fix the gas pipe and the pipe.

When the fitting is connected and fixed between the outlet of the gas cylinder and the pipe, when the gas is used, that is, when the fitting is released during the discharge of the gas from the gas cylinder, there is a danger that the gas may leak or explode. It is necessary to prevent it.

As a related art related to this, Korean Patent No. 10-1520452 (Patent Document 1) discloses a first shoulder portion having a first female thread portion and a second shoulder portion having a second female thread portion spaced apart from the first shoulder portion by a predetermined distance, A casing having a shoulder portion and a bridge portion connecting the first shoulder portion and the second shoulder portion;

A protective cap detachably attached to the first shoulder portion and the second shoulder portion of the casing, the cap having a left-side cap having a cylindrical shape and a right-side cap hinged to the left-side cap; And

And a fastening bolt fastened to the first female threaded portion of the first shoulder portion and the second female threaded portion of the second shoulder portion.

According to such a fitting protection device, the protective cap for the valve handle can be fixedly coupled to the casing for piping fitting in a non-rotated state, thereby preventing malfunctioning or tampering of the handle of the valve. However, The worker must unlock the cover of the protective cover and then remove the casing. On the contrary, in order to prevent the valve handle from operating, the operator must cover the casing again and fix it with the locking means. There is a problem that the manufacturing cost is expensive because the structure is complicated.
