The shut-off valve of structure can improve general existing shut-off valve, it is made to have more practicability.By constantly studying, designing, and pass through
After studying sample repeatedly and improving, the utility model having practical value is created finally.
Invention content
The purpose of this utility model is to provide a kind of shut-off valve of new structure, makes it have good sealing performance and prevents
External force destroys function.
The purpose of this utility model and to solve its technical problem realized using following technical solution.According to this reality
With a kind of shut-off valve of novel proposition, including valve body and spool, wherein being fixed with installation set, valve on the inner wall on the valve body top
Core is located in installation set, is connect by screw thread with installation set, and the spool is equipped with rotatable head and valve rod successively from top to bottom,
In：The rotatable head upper end is recessed inwardly to form groove, and card interface is equipped in groove floor；The valve rod passes through it
The fixed transmission platform in lower end is sequentially connected with globe disk, which offers arc groove, and arc is equipped in groove
Cushion pad, the globe disk lower part and valve seat fitted seal；The globe disk passes through one group of flap set limit respectively around
Position, flap set lower end are stuck in the card slot on globe disk, and upper end is fixed on flap jacket gland, which fixes
On valve rod.
It the purpose of this utility model and solves its technical problem and can also be realized using following technical measures.
Aforementioned shut-off valve, wherein the lower part of the globe disk is coated with resistance to erosion layer.
Aforementioned shut-off valve, wherein the valve rod is sealed with installation set contact position by sealing shroud.
Aforementioned shut-off valve, wherein the valve seat that the valve body contacts sealing with globe disk is equipped with gasket.
The utility model has clear advantage and advantageous effect compared with prior art.By above-mentioned technical proposal, sheet
Utility model shut-off valve can reach comparable technological progress and practicability, and with the extensive utility value in industry, until
There are following advantages less：Have the function of that good sealing performance and anti-external force are destroyed.

Specific embodiment
Further to illustrate that the utility model is to reach the technological means and effect that predetermined goal of the invention taken, below
With reference to attached drawing and preferred embodiment, to according to the utility model proposes shut-off valve its specific embodiment, structure, feature and its
Effect is described in detail as after.
Referring to Fig. 1, it is the structure diagram of the utility model shut-off valve, which includes valve body 1 and spool 3,
Installation set 2 is fixed on the inner wall on wherein described 1 top of valve body, spool 3 is located in installation set 2, connects by screw thread and installation set 2
It connects.
The spool 3 is equipped with rotatable head and valve rod 4 successively from top to bottom.Rotatable head upper end be recessed inwardly to be formed it is recessed
Slot, and card interface is equipped in groove floor, in order to rotational valve core.The valve rod 4 by the fixed transmission platform 7 in its lower end with
Globe disk 8 is sequentially connected, which offers arc groove, is equipped with arc buffering pad 11 in groove, is passed with alleviating
Dynamic impact force between platform 7 and globe disk 8,8 lower part of globe disk and valve seat fitted seal.Before and after the globe disk 8,
Left and right is respectively by 6 limiting of a set of flap set, which covers 6 lower ends and be stuck in the card slot on globe disk 8, and upper end is fixed on valve
On valve jacket gland 5, which is fixed on valve rod 4.
Preferably, the lower part of the globe disk 8 is coated with resistance to erosion layer 12, to prevent 8 long-time erosive wear of flap.
It should be preferably, the valve rod 4 be sealed with 2 contact position of installation set by sealing shroud 10.
Preferably, the valve seat that the valve body 1 contacts sealing with globe disk 8 is equipped with gasket 9, to strengthen sealing.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, although the utility model has been disclosed with preferred embodiment as above, be not limited to the utility model, it is any ripe
