MANOMETER NEEDLE VALVE

摘要

The invention relates to the valve industry, specifically to equipment for operating pipelines, and is intended in particular for the mounting of a manometer monitoring the pressure of a medium being transported along a pipeline. The manometer needle valve comprises a body (1) which is indirectly connected to a rod (2), one end of which is provided with a threaded socket (3). Furthermore, a stuffing box unit (10) of herringbone design and a collar bushing (9) are arranged in the body (1). Said collar bushing is connected to the body by means of a connecting element (12). Furthermore, the body (1) is connected with the aid of a threaded connection to a mounting element (5), which is connected with the aid of annular grooves and a locking ring to the rod (2). Furthermore, the body (1) is equipped with a bleed valve (15).
