Embodiment Construction

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like figure 1 As shown, the embodiment of the present invention includes a valve body 1, a channel lining 2, a cavity lining 3, a cock 4, a valve cover 5, a stuffing box 6, a bracket 7, a cock rod 8, an actuator 9, an anti-static spring 812, Steel ball 813.

[0037] Specifically, as figure 1 , figure 2 , image 3 As shown, the valve body 1 includes a cavity 100 in the center and passages 10 on both sides. The passage 10 and the cavity 100 pass through. The outer edge of the passage 10 is provided with a through hole 11 to facilitate connection with the pipe flange.

[0038] like figure 1 , Figure 5 , Image 6 As shown, the cavity lining 3 is made of ceramic material, in the shape of a barrel, thick at the top and thin at the bottom. The interior of the cavity lining 3 is a cavity 300 conforming to the contour of the coc...

Abstract

The invention provides a ceramic plug valve which comprises a valve body, a cavity lining, channel linings, a plug, a stuffing box, a valve cover, a plug rod, a support and an execution mechanism. The valve body comprises a cavity located at the center and channels located on two sides, and the channels and the cavity are communicated. The cavity lining is made of a ceramic material and is bucket-shaped, the outer wall outline is meshed with the cavity of the valve body, the cavity lining is arranged in the cavity of the valve body, and a first through hole used for fluid to pass is formed in the outer wall. The channel linings are made of a ceramic material and are cylindrical, the channel linings are arranged in the channels of the valve body, the inner ends of the channel linings are connected with the first through hole in an abutting mode, and the outer ends extend to the outer portions of the channels. The plug is made of a ceramic material, a second transverse through hole for fluid to pass is formed in the plug, and the plug is arranged in the cavity lining in a rotating mode. The support is fixed on a valve cover or the valve body. The execution mechanism is fixed on the support, connected with the upper end of the plug rod and used for driving the plug rod to rotate. The valve enables the fluid to flow through the ceramic parts completely, the fluid does not need to be in contact with the non-ceramic parts, and the advantages of the ceramic material are fully reflected.

Description

[0001] technical field [0002] The invention relates to a valve, in particular to a ceramic plug valve. [0003] Background technique [0004] In some complex, harsh and even extreme projects, traditional metal valves have been unable to break through the limits of their materials and cannot meet the design requirements of special working conditions. Therefore, it is an inevitable choice to introduce new ceramic materials into the traditional valve industry. New ceramics, also known as advanced ceramics, fine ceramics, etc., include two categories of structural (or engineering) ceramics and functional ceramics. Different chemical components and crystal phase structures make them have different special properties and functions. [0005] Overall, ceramics have the following advantages: [0006] To prolong the service life, the sealing parts and vulnerable parts of the valve are made of new ceramic structural materials, which improves the wear resistance, corrosion resistan...
