Problems solved by technology

The valve balls in the existing ball valves are usually made of metal (mainly copper) or plastics. The metal valve balls have defects such as liquid leakage after corrosion and fouling of the ball valves, while plastic valve balls have non-wear-resistant Shortcomings, the present invention attempts to solve the above problems

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 , figure 2 The valve ball shown in includes a ball 1 with a layer of anti-corrosion and wear-resistant layer 2 on the outer wall of the ball. In this embodiment, the anti-corrosion and wear-resistant layer 2 is made of PPSU material, or any other suitable material. Wherein the sphere 1 can be a metal sphere or a plastic sphere.

[0014] Polyphenylene sulfone resins (Polyphenylene sulfone resins, PPSU), is an amorphous thermoplastic with high degree of transparency, high hydrolytic stability. Except for strong polar solvents, concentrated nitric acid and sulfuric acid, it is stable to common acids, alkalis, salts, alcohols, aliphatic hydrocarbons, etc. Partially soluble in ester ketones `aromatics, soluble in halocarbons `DM. Good rigidity and toughness, temperature resistance, thermal oxidation resistance...

Abstract

The invention provides a ball of a ball valve. The ball comprises a ball body; the outer wall of the ball body is coated with an anti-corrosive and wear-resisting layer, namely a PPSU (polyphenylene sulfone resin) layer. The ball body is a metal or plastic one; the anti-corrosive and wear-resisting layer is made of the PPSU material and is capable of preventing the ball body from rusting effectively; the PPSU material has the effects of high temperature resistance and corrosion resistance, so that the defects that the ball valve is jammed caused by dirt accumulation or leakage due to metal ball corrosion can be solved.

Description

technical field [0001] The invention relates to a valve ball of a ball valve. Background technique [0002] Ball valve (ball valve should be a globe valve in the field of marine engineering and ships), defined in the standard GB / T21465-2008 "Valve Terminology" as: a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve . In my country, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries. They are mainly used for cutting, distributing and changing the flow direction of media. It only needs It can be closed tightly with the operation of rotating 90 degrees and a small rotating torque. The valve balls in the existing ball valves are usually made of metal (mainly copper) or plastics. The metal valve balls have defects such as liquid leakage after corrosion and fouling of ...
