Abstract
The utility model provides a safe stop valve, which comprises a casing, a valve rod, a spring, a valve core and a two-way valve, wherein the lower part of the valve rod is provided with a step, the spring is sheathed at the step part, the bottom end of the valve rod is connected with the valve core, the casing is connected with the two-way valve, the casing is in an integral structure, the bottom of the valve core is provided with a plurality of column-shaped bulges, the tip parts of the bulges are in a spherical shape, a valve plate is arranged on a valve core hole matched with the valve core, a plurality of column-shaped holes are formed in the valve plate and are matched with the column-shaped bulges for realizing the interruption and the flowing of water, the upper surface of the valve plate is provided with a sealing ring, the sealing ring is provided with projected parts, and the projected parts extend into the column-shaped holes for sealing the column-shaped bulges of the valve core. The safe stop valve has the advantages that the column-shaped bulges are arranged on the valve core, the stress area between the water and the valve core hole is increased, and the pressure intensity is reduced, so the flow leakage of the stop valve is prevented.
Description
Technical field
The utility model relates to a kind of safety type stop valve.
Background technique
Existing safety type stop valve, the cylinder body shape that is traditional type of spool and spool bore, and have only a cylinder, hydraulic pressure is bigger, easily earial drainage.The utility model provides a kind of safety type stop valve, and this stop valve bottom is provided with a plurality of column-shaped projections, and this column-shaped projection matches with valve plate, realizes increasing lifting surface area, reduces pressure, thereby realizes the Security of stop valve.
The model utility content
For solving above technical problem, the utility model provides following technological scheme: a kind of safety type stop valve, described stop valve comprise that housing, valve rod, spring, spool and two lead to, described stem lower portion is provided with step, the step place is with spring, and the bottom of valve rod connects spool, and housing connects two and leads to; Described housing is integral structure, and described spool bottom has a plurality of column-shaped projections, and the tip of projection is spherical; And have valve plate on the spool bore that spool matches, have a plurality of cylindrical holes on the valve plate, this cylindrical hole matches with described column-shaped projection and realizes the disconnected and stream of water; Described valve plate upper surface has seal ring, and seal ring has convex portion, and this convex portion stretches into described cylindrical hole, to the column-shaped projection sealing of spool.
This safety type stop valve that the utility model relates to has a plurality of column-shaped projections on the spool, increase the lifting surface area between water and the spool bore, reduces pressure, thereby, realize preventing the Security of valve earial drainage.
