Description
Technical field
The utility model relates to a kind of spool.
Background technique
As the important component controlling flow direction, the function of spool is more and more valued by the people.But existing spool mostly is a smooth spool disk, when opening/shutting valve, spool disk is large by fluid resistance.Further, due to existing a lot of valve because specification is different, often need the spanner of different size when opening/shutting valve, bring a lot of inconvenience to operator.
Model utility content
The purpose of this utility model is to provide a kind of spool, large by fluid resistance because of spool disk to solve existing valve, and needs dedicated spanner to open and close, causes opening and closing inconvenient problem.
For solving the problems of the technologies described above, the utility model provides a kind of spool, comprises spool disk and is arranged on the valve rod at spool disk top, and spool disk is provided with the radial boss arranged; The top and bottom of boss are respectively equipped with upper flange part and lower flange, and the lower end of valve rod is fixed in upper flange part; Boss both sides are respectively equipped with the triangle valve wing relative to boss symmetry; The surface of two valve wings is streamlined, and its thickness outwards reducing gradually from contiguous boss; The top of valve rod is provided with positioning rod, and positioning rod is provided with valve thimble; Valve thimble is provided with through hole.
Further, valve thimble is threaded with positioning rod.
The beneficial effects of the utility model are: the spool disk of this spool is provided with the valve wing, and the surface of the valve wing is set to streamlined, reduces fluid resistance.In addition, valve stem top of the present utility model is provided with valve thimble and has replaced existing start-stop device, and when opening/shutting valve, need lever pierces in the through hole on valve thimble and spanner can be replaced to complete valve opening and closing operation.

Fig. 1 is the structural representation of the utility model most preferred embodiment;
Fig. 2 is the front view of the utility model most preferred embodiment.
Wherein: 1, spool disk; 11, boss; 12, the valve wing; 13, peak portion; 14, lower flange; 15, upper flange part; 2, valve rod; 21, positioning rod; 3, valve thimble; 31, through hole.
Embodiment
Below embodiment of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of embodiment; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection in appended claim.
Spool as depicted in figs. 1 and 2, comprises spool disk 1 and is arranged on the valve rod 2 at spool disk 1 top, and spool disk 1 is provided with the radial boss 11 arranged; The top and bottom of boss 11 are respectively equipped with upper flange part 15 and lower flange 14, and the lower end of valve rod 2 is fixed in upper flange part; Boss 11 both sides are respectively equipped with the valve wing 12 triangular in shape relative to boss 11 symmetry; The surface of two valve wings 12 is streamlined, and its thickness outwards reducing gradually from contiguous boss 11; The top of valve rod 2 is provided with positioning rod 21, and positioning rod 21 is provided with valve thimble 3; Valve thimble 3 is provided with through hole 31.
According to an embodiment of the application, valve thimble 31 is connected with positioning rod screw thread 21.
The spool disk 1 of this spool is provided with the valve wing 12, and the surface of the valve wing 12 is set to streamlined, reduces fluid resistance.In addition, valve rod 2 top of the present utility model is provided with valve thimble 3 and has replaced existing start-stop device, and when opening/shutting valve, the interior spanner that can replace of through hole 31 only needing a lever to pierce on valve thimble 3 completes valve opening and closing operation.
