FIELD: valves production.
SUBSTANCE: invention relates to pipe fittings, in particular to valves of hydraulic systems loaded with a spring and provided with a breakable element. Novelty of the invention is that the guide rod is designed as a two-stage hollow nozzle. First stage of the rod is made in the form of a polyhedron and is movably interfaced to the inner surface of the guide bushing. Second stage of the rod is cylindrical, in its upper part through holes are made, and at its end there is a carbide tip. Locking nut is mounted on the valve body, which is designed to mount a hydropneumatic compensator or a flexible hose for connection to an autonomous hydropneumatic compensator.
EFFECT: technical result consists in simplification of design and higher valve reliability.
