Embodiment Construction

[0023] The invention provides a ceramic composite coating type corrosion-resistant valve and the coating process of the ceramic composite coating in the corrosion-resistant valve. The invention will be further described below in conjunction with the accompanying drawings:

[0024] A ceramic composite coating type corrosion-resistant valve, including an operating handle, a valve body (4), a ball (2) inside the valve body (4), a valve seat (5), a valve stem (3), and a bearing (6), the operating handle is fixedly connected to the upper end of the sphere (2) through the valve stem (3), and the lower end of the sphere (2) is fixedly connected to the bearing (6). It is characterized in that the corrosion-resistant valve is also A coating is included, and the coating is made of ceramic paint and covers the surfaces of the ball (2), the valve stem (3), the valve body (4), the valve seat (5) and the bearing (6).

[0025] Such as figure 2 As shown, the sealing pair of the ball valve i...

Abstract

The invention relates to corrosion-resistant valve application technology, in particular to a ceramic composite-coating type corrosion-resistant valve and a paint coating process of a ceramic composite coating in the corrosion-resistant valve. The ceramic composite-coating type corrosion-resistant valve is made of a ceramic material resistant to abrasion and corrosion, and valve parts are coated with the ceramic composite coating, so that technical content is high, corrosion resistance is good, and friction coefficient is low; a sealing pair is composed of the coating and a plastic material, so that the ceramic composite-coating type corrosion-resistant valve has the advantages of being low in force of friction, small in switch moment, long in service life and the like; besides, application of the valve in the field of fluid resistant to corrosion is enlarged, corrosion-resistant alloy steel can be replaced in use, and obvious social benefits are achieved.

Description

technical field [0001] The invention relates to a corrosion-resistant application technology of a valve, in particular to a ceramic composite coating type corrosion-resistant valve and a coating process of the ceramic composite coating in the corrosion-resistant valve. Background technique [0002] With the reduction of geological reserves of petroleum and the continuous expansion of offshore oil production platforms, the demand for corrosion-resistant pipelines is increasing day by day. However, the corrosion of valve components by seawater is very serious, and the development of strong corrosion-resistant valves has become an important issue in the development of valves today. [0003] Two-component flexible ceramic anti-corrosion and wear-resistant coating FZV-601, which provides excellent wear resistance and corrosion resistance in special environments, is suitable for all metal materials, glass steel, etc. It is mixed with high-performance epoxy resin and ceramic high-f...
