Abstract

The invention discloses a thermal ball valve resistant to leakage. The thermal ball valve resistant to leakage comprises a sphere. Floating valve seats are connected with the two sides of the sphere.Buffer limiting mechanisms are connected with both the upper end and the lower end of the side, close to the sphere, of each floating valve seat. According to the thermal ball valve resistant to leakage, a valve rod is made of 20Cr13 stainless steel, the valve rod is high in torsional strength and smooth in machined surface, and a lubricating sealing effect is improved; the valve rod is installedfrom the lower part of the interior of a valve rod connecting sleeve, pressure is pushed towards the valve rod by using a thrust washer support made of a low-friction material, and therefore the valverod only plays a role in transmitting torque without generating load; meanwhile, because the valve seats are composed of carbon fiber reinforced polytetrafluoroethylene and springs, self lubrication,friction resistance and resistance to temperature as high as 200 DEG C are achieved; an O-shaped sealing ring is made of VITON fluororubber, and thereby being good in temperature resistance, resistant to friction and high in corrosion resistance; and a first sealing ring is assembled at a low temperature, and thereby being high in adaptive capacity of changes of pressure and temperature, and no leakage is likely to happen within the marked range of pressure and temperature.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to an anti-leakage thermal ball valve. Background technique [0002] With the development of society, the rapid development of modern large-scale machinery, petroleum, chemical industry, new energy, nuclear industry and other industries, the requirements for valve sealing and safety and reliability are getting higher and higher. The thermal ball valve used in china is deficient in both stability and tightness, the service life is not long, and it is easy to damage and require maintenance. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an anti-leakage thermal ball valve in order to solve the above problems, which solves the existing problems. [0004] In order to solve the above-mentioned problems, the present invention provides a kind of technical scheme: [0005] An anti-leakage thermal ball valve, comprising a sphere, a floating valve seat ...
