Abstract
The utility model provides a high temperature high pressure ball valve, which comprises the following components: a valve body, the spheroid, the upper valve rod, the lower valve rod, be equipped with the spheroid in the valve body, spheroid upper end middle part and upper valve rod fixed connection, spheroid lower extreme middle part coaxial rotation install on the lower valve rod, the lower extreme of valve body is equipped with the valve gap, the valve gap passes through the fastener to be fixed on the valve body, the lower valve rod runs through the valve gap and passes through fastener fixed mounting on the valve gap, the lower valve rod is T shape, its " 1 " font position segment table face is opened flutedly, be equipped with sealing element in the recess, be used for and the valve gap between sealed, lower valve rod " one " font position section and the surperficial butt of valve gap, and be equipped with radial open -ended C shape sealing washer between the two, the opening direction of C shape sealing washer is directional central, and the material of C shape sealing washer is economet. The beneficial effects of the utility model are that: C shape sealing washer has the effect of energy storage, direction and sealed the laminating radial and valve gap about can realizing, better assurance the sealing performance of valve.
Description
Art
The utility model relates to a kind of valve, particularly relates to a kind of ball valve.
Background technique
The ball valve of currently available technology, lower valve rod place uses wound gasket to seal usually, the shortcoming that this sealing means exists can only form end face seal between valve gap and lower valve rod, and sealing can not be realized diametrically, medium very easily leaks from radial clearance, special under high temperature and high pressure condition, more easily cause the generation of leakage accident.
Model utility content
In order to overcome the above-mentioned shortcoming of existing ball valve, the utility model provides a kind of high-temp and-pressure ball valve of safe and reliable, good seal performance.
The utility model solves the technological scheme that its technical problem adopts, a kind of high-temp and-pressure ball valve, comprise valve body, spheroid, upper valve rod, lower valve rod, spheroid is provided with in valve body, spheroid upper center is fixedly connected with upper valve rod, in the middle part of spheroid lower end, coaxial rotation is arranged on lower valve rod, the lower end of valve body is provided with valve gap, valve gap is fixed on valve body by fastening piece, lower valve rod runs through valve gap and is fixedly mounted on valve gap by fastening piece, lower valve rod is T-shaped, its " 1 " font position section surface has groove, seal element is provided with in groove, for sealing between valve gap, lower valve rod " one " font position section abuts with valve cover surfaces, and is provided with the C shape seal ring of radial opening between the two, and the opening direction of C shape seal ring points to center, and the material of C shape seal ring is nichrome.
The beneficial effects of the utility model are: be equipped with seal element in vertical section and horizontal segment between lower valve rod and valve gap, define double seal, and the self structure of C shape seal ring, there is the effect of accumulation of energy, when medium enters, the sealing that not only can realize C shape seal ring upper and lower end face and valve gap is fitted, and also achieves its sealing that is radial and valve gap and fits, better ensure that the sealability of valve; Further, the employing of C shape seal ring is nichrome material, go for high temperature and high pressure condition.
