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 present invention having practical value is created finally.
Invention content
The object of the present invention is to provide a kind of shut-off valves of new structure, make it have good sealing performance and anti-external force
Destroy function.
The object of the invention to solve the technical problems is realized using following technical solution.It carries according to the present invention
A kind of shut-off valve gone out, including valve body 1 and spool 3, wherein being fixed with installation set 2, spool 3 on the inner wall on 1 top of the valve body
In installation set 2, it is connect by screw thread with installation set 2；The spool 3 is equipped with rotatable head, 4 and of valve rod successively from top to bottom
Globe disk 5, wherein rotatable head upper end are recessed inwardly to form groove, and card interface is distributed in slot bottom；The valve rod 4 and peace
2 contact position of encapsulation is sealed by sealing shroud 8；The spherical seal surface of the flap 5 is equipped with abrasion sealer 7；The valve body 1 with
The valve seat of the contact sealing of flap 5 is equipped with gasket 6.
The present invention has clear advantage and advantageous effect compared with prior art.By above-mentioned technical proposal, the present invention
Shut-off valve can reach comparable technological progress and practicability, and have the extensive utility value in industry, under at least having
Row advantage：Have the function of that good sealing performance and anti-external force are destroyed.
