Abstract
The invention discloses a self-sealing ball valve which comprises a valve body, a valve cover and a valve seat, wherein the valve seat consists of an elastic metal piece, the valve seat is provided with an annular channel which has an outward opening and is annularly distributed. Because the valve seat of the self-sealing ball valve consists of the elastic metal piece, and the valve seat is provided with the annular channel, the valve seat can automatically carry out the sealing compensation, the integral valve seat structure with the sealing compensation performance is firmer, and the parts are reduced (originally, the valve seat and a disk spring form the sealing compensation) so as to lead the production and the assembly to be more convenient.
Description
Technical field
The present invention relates to a kind of self-sealing ball valve.
Background technique
In the market between the parts at the valve seat of the seal ball-valve of Xiao Shouing and its place the operated by rotary motion belleville spring strengthening sealability, but the structure of valve seat and belleville spring split is not easy to installation, and the fastness of structure and stability are all poor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of self-sealing ball valve, and its valve seat not only has the sealing compensation performance and fastness is better, it is easier to install.
For this reason, self-sealing ball valve provided by the invention comprises valve body, valve gap and valve seat, and valve seat is made of resilient metal member, has the annular ditch that opening distributes and ringwise on the valve seat outwardly.
Because the valve seat of self-sealing ball valve provided by the invention is made of resilient metal member, and valve seat has annular ditch, therefore valve seat can be made sealing compensation voluntarily, this integrated type valve seat construction with sealing compensation performance is more firm, and because parts reduce (originally constituting sealing compensation by valve seat and belleville spring) makes and produce and assemble convenient.
Description of drawings
It among the figure structure cross-sectional schematic of self-sealing ball valve provided by the invention.
Embodiment
As shown in the figure, self-sealing ball valve provided by the invention, comprise valve body 1, valve gap 2 and valve seat 3, valve seat 3 is made of resilient metal member, has opening on the valve seat 3 and the annular ditch 4 that distributes ringwise outwardly, and annular ditch 4 is outwardly pressed close to valve gap 2 or valve body 1, annular ditch 4 distribution that takes the shape of the letter U, the U-shaped structure can not produce stress and concentrate, and offers circular groove 5 on valve seat 3 outer side surfaces, is provided with seal ring 6 in the circular groove 5.Ball valve flap both sides are provided with valve seat 3 respectively in the present embodiment, left side valve seat 3 is arranged on the ring-shaped step 7 of valve gap 2, right side valve seat 3 is arranged on the step surface 8 of valve body 1, also can valve seat provided by the invention be set in flap one side in practical operation, and opposite side is done common processing.
