Description
Technical field:
The utility model relates to a kind of ball valve, particularly relates to a kind of ball valve.
Background technique:
Ball valve is a kind of open-shut device is spheroid, is driven and the valve rotated around ball valve axis by manipulation valve rod, mainly in order to the regulating and control of fluid, the various pipes in production and life all has a wide range of applications.In production pipeline, when hydrodynamic pressure is excessive, the torsion of twisting needed for spheroid is also along with change is large, and sphere friction is seriously impaired, greatly reduces the life-span of spheroid; And under the environment of some outdoors, ball valve is easy to be opened by mistake and miss pass, brings inconvenience to user.
Model utility content:
For the deficiencies in the prior art, the utility model provides a kind of ball valve, is made up of valve body, valve gap, valve seat, spheroid, spanner.
The utility model solves the technological scheme that its technical problem adopts: be provided with flow ipe and outflow conduit in valve body, spheroid is provided with between flow ipe and outflow conduit, the both sides of spheroid are respectively equipped with valve seat, valve seat with the surface of contact of spheroid on be provided with Sealing shield ring; Be provided with manhole bottom spheroid, spheroid top is provided with tapped through hole, upper valve rod through the tapped through hole at spheroid top and spheroid tightly fixing; Valve body is provided with valve gap, and valve gap top is provided with lock dog, and described lock dog is made up of two pieces of sheet metals, and two pieces of described sheet metals are vertically arranged, and sheet metal is provided with round keyhole; Upper valve rod and valve gap surface of contact are provided with Gland, are provided with filler in Gland, in order to seal upper valve rod; Valve gap with the surface of contact of upper valve rod on to have returned the car circular groove, groove is embedded with seal ring, and valve gap top connects spanner, and the spanner the other end is provided with round keyhole, is conveniently locked with the lock dog at valve gap top; Body base intermediate portion is provided with bottom, and the both sides of bottom are provided with through hole, and socket head screw is fixed on valve body through through hole by dismountable for bottom; Bottom is provided with lower valve rod, and lower valve rod penetrates in the manhole bottom spheroid, lower valve rod with spheroid surface of contact on be provided with plain thrust bearing, lower valve rod and spheroid surface of contact outer wall are provided with seal ring.
The beneficial effects of the utility model: reduce the friction extent of damage of spheroid, prevent from being opened by mistake pass.
Accompanying drawing illustrates:
Fig. 1 is overall structure figure of the present utility model;
Wherein, 1-valve body, 2-valve gap, 3-valve seat, 4-spheroid, 5-spanner.
Embodiment:
A kind of ball valve as shown in drawings, be made up of valve body 1, valve gap 2, valve seat 3, spheroid 4, spanner 5, flow ipe and outflow conduit is provided with in valve body, spheroid is provided with between flow ipe and outflow conduit, the both sides of spheroid are respectively equipped with valve seat, valve seat with the surface of contact of spheroid on be provided with Sealing shield ring; Be provided with manhole bottom spheroid, spheroid top is provided with tapped through hole, upper valve rod through the tapped through hole at spheroid top and spheroid tightly fixing; Valve body is provided with valve gap, and valve gap top is provided with lock dog, and described lock dog is made up of two pieces of sheet metals, and two pieces of described sheet metals are vertically arranged, and sheet metal is provided with round keyhole; Upper valve rod and valve gap surface of contact are provided with Gland, are provided with filler in Gland, in order to seal upper valve rod; Valve gap with the surface of contact of upper valve rod on to have returned the car circular groove, groove is embedded with seal ring, effectively prevents fixing granule from slipping into or being stuck on upper valve rod; Valve gap top connects spanner, and the spanner the other end is provided with round keyhole, and lock dog that is convenient and valve gap top is locked, and prevents spanner from being opened by mistake or closes by mistake; Body base intermediate portion is provided with bottom, and the both sides of bottom are provided with through hole, and socket head screw is fixed on valve body through through hole by dismountable for bottom; Bottom is provided with lower valve rod, lower valve rod penetrates in the manhole bottom spheroid, lower valve rod with spheroid surface of contact on be provided with plain thrust bearing, effectively reduced the driving torque of upper valve rod by plain thrust bearing, reduce the friction extent of damage of spheroid, reduce working strength; Lower valve rod and spheroid surface of contact outer wall are provided with seal ring.
