Abstract
The utility model devises a kind of high-performance floating ball valve, comprise valve seat, valve body, spheroid, valve rod and handle, valve body is provided with flow pass and flow channel, valve pocket is provided with between flow channel and flow pass, valve pocket two ends are respectively equipped with valve seat, be provided with spheroid between two valve seats, valve seat with the surface of contact of spheroid on be provided with O-ring seals; Annular spring is provided with between valve seat and valve body; Protective gear is provided with in annular spring surrounding, described protective gear is hollow cylindrical, and protective gear is set with by three joint hollow cylinders and forms, and hollow cylinder is slidably, three joint hollow cylinder chi footpaths reduces successively, chi footpath maximum one joint hollow cylinder be connected with the base of annular spring; Described valve body upper end is provided with valve rod hole, and valve rod is through valve rod hole, and the flat notch on valve rod one end and spheroid patches and connects and composes circumference and be located by connecting, and the valve rod the other end is provided with handle.The utility model effectively prevents solid granule from blocking spring mistake spring and loses floating performance, very easy to use.
Description
Technical field:
The utility model relates to a kind of ball valve, particularly relates to a kind of high-performance floating ball valve.
Background technique:
The open-shut device of ball valve is spheroid, and user controls turning to of spheroid by the rotation of Joystick, to reach the opening and closing of valve.In existing floating ball valve, when mix in fluid have solid granule time, solid granule is very easy to the spring blocked on valve seat, spring is caused to follow the string, valve seat loses floating performance, thus causes great impact to the sealability of entirety, brings great inconvenience to user.
Model utility content:
For the deficiencies in the prior art, the utility model devises a kind of high-performance floating ball valve, comprises valve seat, valve body, spheroid, valve rod and handle.
The utility model solves the technological scheme that its technical problem adopts: valve body is provided with flow pass and flow channel, valve pocket is provided with between flow channel and flow pass, valve pocket two ends are respectively equipped with valve seat, be provided with spheroid between two valve seats, valve seat with the surface of contact of spheroid on be provided with O-ring seals; Be provided with annular spring between valve seat and valve body, described annular spring one end is fixed on valve seat by spring underframe, and the annular spring the other end contacts with valve body; Protective gear is provided with in annular spring surrounding, described protective gear is hollow cylindrical, and protective gear is set with by three joint hollow cylinders and forms, and hollow cylinder is slidably, three joint hollow cylinder chi footpaths reduces successively, chi footpath maximum one joint hollow cylinder be connected with the base of annular spring; Described valve body upper end is provided with valve rod hole, and valve rod is through valve rod hole, and the flat notch on valve rod one end and spheroid patches and connects and composes circumference and be located by connecting, and the valve rod the other end is provided with handle, and handle is provided with positive stop; Described valve rod is provided with gland near valve rod hole top, is provided with filler between this gland and valve rod hole top.
The beneficial effects of the utility model: effectively prevent solid granule from blocking spring mistake spring and lose floating performance, very easy to use.
Accompanying drawing illustrates:
Fig. 1 is main TV structure figure of the present utility model;
Fig. 2 is protective gear structural drawing of the present utility model;
Wherein, 1-valve seat, 2-valve body, 3-spheroid, 4-valve rod, 5-handle.
Embodiment:
The utility model devises a kind of high-performance floating ball valve, comprise valve seat 1, valve body 2, spheroid 3, valve rod 4 and handle 5, valve body 2 is provided with flow pass and flow channel, valve pocket is provided with between flow channel and flow pass, valve pocket two ends are respectively equipped with valve seat 1, be provided with spheroid 3 between two valve seats 1, valve seat 1 with the surface of contact of spheroid 3 on be provided with O-ring seals; Be provided with annular spring between valve seat 1 and valve body 2, described annular spring one end is fixed on valve seat 1 by spring underframe, and the annular spring the other end contacts with valve body 2; Protective gear is provided with in annular spring surrounding, described protective gear is hollow cylindrical, and protective gear is set with by three joint hollow cylinders and forms, and hollow cylinder is slidably, three joint hollow cylinder chi footpaths reduces successively, chi footpath maximum one joint hollow cylinder be connected with the base of annular spring; Described valve body upper end is provided with valve rod hole, and valve rod is through valve rod hole, and the flat notch on valve rod one end and spheroid patches and connects and composes circumference and be located by connecting, and the valve rod the other end is provided with handle 5, and handle 5 is provided with positive stop; Described valve rod 4 is provided with gland near valve rod hole top, is provided with filler between this gland and valve rod hole top.
The utility model is by being provided with the hollow cylinder of three joint suits, and hollow cylinder is enclosed within the surrounding of annular spring, effectively prevents solid particle to slip in annular spring; When valve seat floats, three joint hollow cylinders also float along with valve seat shrinks, very easy to use.
