Embodiment Construction
[0007] As shown in the figure, the new type of strong acid and strong alkali resistant ball valve is sprayed with titanium alloy material on all parts in contact with the medium. After the titanium alloy material is sprayed, the ball 3 is manufactured using advanced grinding equipment and technology. , to ensure the high precision of the spherical roundness surface, all the contact parts between the metal and the titanium alloy are hot-fitted, the combination is firm and reliable, and the mechanical strength of the titanium alloy is enhanced.

The invention relates to the technical field of valves, in particular to a novel strong acid and strong alkali resistant ball valve, which is characterized by comprising a valve rod, packing, a ball, a valve seat and a valve body, titanium alloy materials are sprayed on all portions contacting with media, the ball is manufactured by advanced grinding equipment and process after the titanium alloy materials are sprayed, high precision of the roundness surface of the ball is ensured, the ball has self-lubrication of titanium alloys after facing up with the valve seat, fine sealing performance can be achieved, all portions of metal contacting with the titanium alloys are firmly and reliably combined by means of hot matching process, and the mechanical strength of the titanium alloys is enhanced. The novel strong acid and strong alkali resistant ball valve has the advantages that the ball valve can be used for high-hardness granular media and corrosive media with soft grains, the service life of the ball valve is prolonged, use limitations of a traditional ball valve are broke through, difficulty in production is reduced, and batch production is facilitated.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a novel strong acid and alkali resistant ball valve. Background technique [0002] The ball valve is evolved from the plug valve. It has the same action of rotating 90 degrees, but the difference is that the cock body is a sphere with a circular through hole or channel passing through its axis. The ratio of the spherical surface to the channel opening should be such that when the ball is rotated 90 degrees, all spherical surfaces should appear at the inlet and outlet, thereby cutting off the flow. However, the ball bears the load and corrosion of the working medium, especially in the case of strong corrosion, which will cause the valve to fail, thus limiting the application of the ball valve. Contents of the invention [0003] The purpose of the present invention is to overcome the limitations of the ball valve and provide a new type of ball valve with wider application range ...
