Abstract
The utility model relates to a strengthen canned type ball-cock assembly, including the valve body, the valve shaft is installed to the upper and lower end of valve body, and the butterfly plate passes through the round pin to be fixed on the valve shaft, and the valve body sealing washer is installed to the interior circumference of valve body, and the valve body sealing washer has the sealed face of round platform shape, and the outer circumference of butterfly plate is formed with the sealed face matched with spherical sealing face of round platform shape the side of the outer circumference of butterfly plate still through the clamp plate pressure equipment with the sealed face matched with lubrication sealing washer of round platform shape on the valve body sealing washer, the clamp plate passes through. The utility model discloses a strengthen canned type ball-cock assembly both have good sealing performance, have less switching torque again.
Description
Technical Field
The utility model relates to a ball valve revolves, specific saying so relates to an strengthen canned type ball valve revolves.
Background
The ball valve among the prior art installs the valve shaft at the upper and lower end of valve body, and the butterfly plate is fixed on the valve shaft, and the valve body sealing washer is installed to the circumference in the valve body, and the valve body sealing washer has the sealed face of round platform shape, and the outer circumference of butterfly plate has the sealed face of sphere of matched with the sealed face of round platform shape, because the sealed face of round platform shape of valve body sealing washer and the sealed face of sphere of butterfly plate are metal material and make, so this kind of structure exists following several not enoughly: firstly, the friction force is large when the valve is opened and closed, so that the opening and closing torque is large; and secondly, a small gap exists between the truncated cone-shaped sealing surface and the spherical sealing surface, so that the sealing effect of the valve is reduced.
Disclosure of Invention
The utility model discloses the problem that needs to solve provides a strengthen canned type ball-cock assembly that has both had good sealing performance, has less opening, closing moment again.
For solving the technical problem, the utility model discloses a strengthen canned type ball-rotating valve includes the valve body, including the valve body, the valve shaft is installed to the last lower extreme of valve body, and the butterfly plate passes through the round pin to be fixed on the valve shaft, and the valve body sealing washer is installed to the interior circumference of valve body, and the valve body sealing washer has the sealed face of round platform shape, and the outer circumference of butterfly plate is formed with the sealed face matched with spherical sealing face with the sealed face of round platform shape the side of the outer circumference of butterfly plate still through the clamp plate pressure equipment with the sealed face matched with lubrication sealing of round platform shape on the valve body sealing washer, the clamp.
As a further improvement, the utility model discloses a work as the clamp plate pressure equipment is in lubricated sealing washer on, the gap has between the face of clamp plate and butterfly valve, can adjust the size in gap through adjusting the clamp plate screw.
By adopting the rotary ball valve with the structure, the lubricating sealing ring is in sliding contact with the valve body sealing ring in the opening and closing processes of the valve, so that a layer of lubricating film is formed on the circular truncated cone-shaped sealing surface of the valve body sealing ring, and the relative friction force between the circular truncated cone-shaped sealing surface of the valve body sealing ring and the spherical sealing surface of the butterfly plate is reduced after the layer of lubricating film is formed, so that the torque of the valve during opening and closing is reduced; meanwhile, the lubricating film can fill a tiny gap between the truncated cone-shaped sealing surface of the valve body sealing ring and the spherical sealing surface of the butterfly plate when the valve is closed, so that the sealing performance of the valve is improved, the lubricating sealing ring can be restored to the optimal state by adjusting the screw on the pressure plate after being used for a period of time, and the service life of the lubricating sealing ring is prolonged. The utility model discloses in adopt and constitute double seal structure between the round platform shape of lubricated sealing washer and the combination of the spherical sealed face of butterfly plate and valve body sealing washer sealed face, sealed effect is better.
