Abstract
The utility model provides a fixed ball valve that cuts off fast of forged steel, includes valve body, valve gap and valve rod, opens the passageway that has a perfect understanding about having on the valve body, the valve rod is connected with the spheroid of control channel break -make, install in the passageway with ball sealing complex disk seat, have a perfect understanding about being equipped with on the spheroid, the even circular through -hole of internal diameter size, the right -hand member of circular through -hole is equipped with triangle -shaped's the portion of blocking, blocks the inboard part of position in circular through -hole. At the in -process that the spheroid was closed, the portion of blocking accelerates the speed blocked. The utility model has the advantages of reasonable design for the passageway is blocked to the spheroid, and the effective control flow has strengthened sealing performance, is favorable to extensive popularization.
Description
Technical field
The utility model relates to valve technology field, particularly relates to a kind of forged steel and fixes fast cut-off ball valve.
Background technique
Ball-valve structure many employings part-turn electric actuator of current use drives ball valve body, performs 90 degree of rotations, realizes valve opening and closing.For meeting certain output torque, electric actuator speed ratio is comparatively large, and angular velocity is slow, and often the valve closing time is more than tens seconds, and the ball valve shut-in time that bore is greater than DN100 even reached for tens seconds, and therefore cut-off velocity is slow.
Model utility content
The utility model will solve above-mentioned prior art Problems existing, provides a kind of forged steel to fix fast cut-off ball valve, accelerates cut-off velocity, reasonable in design.
The utility model solves the technological scheme that its technical problem adopts: fast cut-off ball valve fixed by this forged steel, comprise valve body, valve gap and valve rod, valve body has the passage that left and right is through, valve rod is connected with the spheroid of control channel break-make, the valve seat coordinated with ball seal is installed in passage, spheroid is provided with that left and right is through, internal diameter manhole of uniform size, and the right-hand member of manhole is provided with leg-of-mutton blocking unit, and blocking unit is positioned at the inboard portion of manhole.In the process that spheroid is closed, blocking unit accelerates the speed blocked.
In order to perfect further, manhole left end opening is provided with rounding.Fit between such spheroid and valve seat more tight, better tightness, reduces wear.
Perfect further, between valve seat and valve body, spring support is installed.Make valve seat have certain elasticity like this, make sealing between valve seat and spheroid better, reduce wear.
Perfect further, be provided with fire-resistant packing ring between spring support and valve seat, the outer wall of valve seat has groove, and fire-resistant packing ring is positioned at groove.
Perfect further, valve seat the inner is embedded with edge circle.
The effect that the utility model is useful is: the utility model reasonable in design, accelerates spheroid and blocks passage, effectively control flow, enhance sealability, be conducive to extensive popularization.
