Embodiment Construction
[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0037] Refer below Figure 1 to Figure 4 To further explain this application, such as figure 1 and figure 2 A ceramic double-gate fly ash valve shown includes a main valve body 10, a pair of side valve bodies 20, a valve stem 80, a gate frame 70, an outer top device 50, a left gate 31 and a right gate 32 . A pair of side valve bodies 20 are respectively mounted on both sides of the main valve body 10 , and both sides of the main valve body 10 are fixed and sealed with the side valve bodies 20 through bolts 90 . The valve stem 80 is movably arranged on the main valve body 10, and a packing sealing device is arranged between the main valve body 10 and the valve stem 80. The packing sealing device is composed of packing 100 It is composed of packi...

The invention provides a ceramic double-gate-plate flying ash valve. The ceramic double-gate-plate flying ash valve comprises a main valve body, a pair of side valve bodies, a valve rod, a gate plateframe, an outer top device, a left gate plate and a right gate plate; the pair of the side valve bodies are arranged on the two sides of the main valve body respectively, ceramic valve seats are botharranged in the pair of the side valve bodies, the valve rod is movably arranged on the main valve body, the gate plate frame is arranged at the lower end of the valve rod, and the outer top device isarranged on a column body at the lower end of the gate plate frame; and the left gate plate is arranged on the left side of the column body in a floating mode through the outer top device, and the right gate plate is arranged on the right side of the column body in a floating mode through the outer top device. According to the ceramic double-gate-plate flying ash valve, due to the adoption of thestructure, the wear resistance, the corrosion resistance and the washing resistance can be obtained; and moreover, the sealing performance is reliable, and the service life is long and the like.
Description
technical field [0001] The invention relates to a valve, in particular to a ceramic double gate fly ash valve. Background technique [0002] The valve is a control component in the pipeline fluid conveying system, which is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cut-off, throttling, check, diversion or overflow and pressure relief. [0003] In mines, coal mines, cement plants, power plants and other dry ash pneumatic conveying process pipelines, the medium is often conveyed under pressurized or negative pressure. For example, the pipeline for pneumatically conveying dry ash in a power plant is conveyed by introducing pressure or vacuuming the pipeline. The dry ash moves at a high speed under the action of air pressure, just like a high-speed rotating grinding wheel, which causes rapid wear and tear on the pipeline equipment. General metal structure valves are very It is quickly worn out and loses its cut-o...
