Unload valve body ball valve is erroneous for installation and inconvenient internal overhaul, valve body need to be disassembled in maintenance from pipeline, influence to set
Received shipment row.
For example, one kind disclosed " floating ball valve ", notification number CN202327198U, including valve in Chinese patent literature
Body, valve deck, sphere and valve rod, valve body connect setting with valve deck, and stem bottom connect setting with sphere, is equipped with valve seat in valve body,
Sphere is adapted setting with valve seat, it is characterized in that: corresponding to valve rod connection on the sphere is equipped with sphere through-hole.Although will
Valve body connect setting with valve deck, but such ball valve still needs to remove valve body in maintenance, will overhaul after the separation of entire valve body,
It is relatively complicated.
Utility model content
The utility model is to overcome the flange bolt of the prior art and valve body are interfered, installation and repairing process is cumbersome to ask
Topic provides the spherical upper-mounting type ball valve of a kind of reduction bolt and valve body interference.
To achieve the goals above, the utility model uses following technical scheme: a kind of spherical shape upper-mounting type ball valve, including valve
Body, valve seat, valve deck, sphere and valve rod, characterized in that the valve body is in hollow tubular, and valve body hollow part is block channels, institute
The valve deck stated is located on body wall, is fixedly connected with the valve body, and the sphere is located at valve body hollow part, the center of the sphere
Place is equipped with the empty slot cooperated with block channels, and the valve rod passes through valve deck and connect with sphere, and the valve seat is located at sphere two
The upper end of side, the valve seat is connect with valve deck, and the valve body is in spherical close to the outer wall of ball position.Valve seat is for limiting sphere
Position, valve rod is used to control the direction of rotation of sphere, and valve deck is for fixing valve rod and valve seat, by valve deck come fixed valve base,
Directly sphere and valve seat from top to bottom can be put into valve body during installation, convenient and efficient, spherical valve outer wall not only increases
Valve intensity, while also reducing the interference of both ends flange bolt installation space.
Preferably, the valve rod is equipped with valve rod protrusion, it is equipped with and valve rod protrusion on the valve deck close to sphere side
The limiting groove of cooperation is additionally provided with thrust washer in the limiting groove.The cooperation of valve rod protrusion and limiting groove can be kept away
Exempt from stem dropping, the setting of thrust washer can improve the stability of ball valve to the pressure of sphere by fluid in buffering pipe.
Preferably, the junction of the valve seat and sphere is equipped with joint face, the joint face and sphere outer wall cooperate, institute
It states and is additionally provided with sealing element on joint face.The cooperation of joint face and sphere outer wall, so that the connection between sphere and valve seat is closer,
Sealing element on joint face is usually seal coating or sealing inlay, can be avoided fluid or sundries in block channels and enters ball
Valve.
Preferably, the junction of the valve seat and valve body, valve deck and valve body, valve rod and valve deck, is equipped with sealing ring.Valve
The setting of sealing ring between body and each component avoids fluid from flowing out ball valve, sealing ring uses O for promoting the leakproofness of ball valve
Type circle, the O-ring of seating position also have elastic reaction, guarantee that valve seat is fitted closely with sphere.
Therefore, the utility model has the following beneficial effects:
(1) it is easily installed, repairs；
(2) stability is high；
(3) structure is simple, easy to process.
