Sealing valve with long body and connecting and sealing ends

摘要

A spring component (24), neutralisable in its effect by an operating mechanism, compresses the sealing plug (16). The valve body (1) has a tubular body (4), to which a sealing cylinder (8) enclosing the sealing plug is connected. The internal width of the sealing cylinder is greater than that of the tubular body. In the valve through passage (5,9) in the transition area between the tubular body and the sealing cylinder, a conical stop shoulder (7) is formed, on which the conically inclined sealing plug is located. The operating mechanism incorporates a pressure piston (18) provided with an axial through passage (19) and engaging from the sealing side in the valve through passage. This piston presses the operating mechanism against the sealing plug.
