First, the use this product installment in front of the boiler burner entrance on the powdered coal pipeline, may shut off the pulverizer and between the boiler burner relation, guarantees the system overhaul the need.Second, technical performance parameter1. Structure pattern: Extracts the type flapper structure; 2. Model specification: MC/MH-II Φ646×120; 3. Pipeline specification: Φ610×10; 4. Installs thickness: 120mm5. Actuating medium: Hot blast, powdered coal mixture; 6. Medium temperature: ：≤200℃;7. Working pressure：≤0.2MPa；8. Leakage rate: 0.9. Internal leakage rate：≤0.1%； 10. With pipeline connection way: The flange connection (matches for counter-flange and connection fastener); 11. Drive type: Manual; 12. Handwheel diameter: Φ400;Third, the structure characteristics.1. manually inserted in the body, board trap, tight institutions, mechanical transmission system (see diagram) structure.2 .the trap door open and close by the interpolation plate structure.In the open, circulation medium in the body without resistance, it is completely open by the channel, to prevent the coal in the valve.Pressure seal cant, and have sealed the wind to seal to prevent leakage medium.Ensure shutoff will circulation medium complete partition.3. flashboard and choose heat-resistant stainless steel materials by mechanical processing, ensure good sealing performance when closed, but also has stronger resistance to change characteristics and corrosion resistance, and open and close, board has cleared seats, accumulate dust to .4. The valve chest for the whole wear-resisting cast steel, the packing surface precision work manufacture, guaranteed the valve chest the rigidity, the resistance to wear and the sealing property, uses when the cold hot condition, not easy to have the distortion.5. The flapper pulls out the terminal the seal, selects the flexible graphite, the seal reliable, the life is long, is thermostable.The padding gland has the adjustment leak-proof function, guaranteed nothing more than leaks out.6. The valve opens shuts is equipped with the reliable lead screw rotation system, guaranteed the normal use opens shuts.Fourth, the principle of work flapper under the lead screw function, realization shutting down or opens.Flapper on wear-resisting packing surface and guide rail movement, when the valve shuts down, the flapper under the lead screw function, according to guides the nail guiding along the packing surface shutting down entire overflow channel, simultaneously, the flapper eliminates accumulates the powder to keep nearby the packing surface the medium.The flapper wedges tightly under the action of force in the incline, causes the flapper adpressed packing surface, from this has guaranteed the packing surface seal; When the valve opens, under the lead screw function, extracts the flapper, medium in entire overflow channel free from obstacle passing.Fifth, equipment loading and unloading notice 1. After the equipment opens a box should read the instruction for use carefully.2. Before the equipment hoisting up, removes the set bolt.Sixth, equipment setup 1. Before the installment, should carry on the inspection to the equipment, pays attention to various parts is whether complete, whether there is damages or the distortion, whether various fasteners do have become less crowded.2. Flows to the product label according to the medium to show the equipment and the pipeline carries on the bold fastening and fastens the connecting bolt.Seventh, maintenance of equipment1. Opens the frequency according to the valve which, closes, scours regularly for the transmission spot, refuels.2. The valve uses for three months to inspect the padding gland the seal situation, if has the air leakage, should fasten the padding gland bolt evenly.3. Whether there is should the periodic inspection fastener become less crowded.Attaching: The flapper gate installs the schematic drawing.

A, useThis product installation in pulverized coal burners before entry pipeline, can cut coal boiler burner and the connection between the need to guarantee system maintenance.Second, the technical parameters1 structure types: drawer-type board structure,2 specifications: MC/MH Φ II - 1127 x 120,3 piping specifications: Φ 610 million,4:12 mm thickness of installation,May: air, coal mixture,6 medium temperature: more than 200 ° c,7. Working pressure: than 0.2 MPa,8. Leakage rate: 09 leakage rate than 0.1%; :10 and piping connections: flange (match for the flange and connection fasteners),11. Driving mode: manual,12 the handwheel diameter: Φ 400,Third, the structure characteristics1 manually inserted in the body, board trap, tight institutions, mechanical transmission system (see diagram) structure.2 the trap door open and close by the interpolation plate structure. In the open, circulation medium in the body without resistance, it is completely open by the channel, to prevent the coal in the valve. Pressure seal cant, and have sealed the wind to seal to prevent leakage medium. Ensure shutoff will circulation medium complete partition.3 flashboard and choose heat-resistant stainless steel materials by mechanical processing, ensure good sealing performance when closed, but also has stronger resistance to change characteristics and corrosion resistance, and open and close, board has cleared seats, accumulate dust to ensure smooth closed plug-in boards.4 for the whole body sealing, wear-resisting cast steel manufacturing, to ensure the precision of the rigid body resistance, heat, and the sealing performance in use, easy deformation.5 the seal, pulled board, choose flexible graphite sealing is reliable, long service life, high temperature resistant. Gland has the function of regulating sealing, choosing leakage.6 the reliable on-off valves with rotation system, ensure the pole normal use.Four, principle of workBoard in silk, realize closed or open. Board in sealing and guide the sport wear, when the valve is closed, the board in the silk, according to the direction of the sealing off the seeker, at the same time, the circulation of cleaning out board in the medium sealing side powder. Board in slant chocking force, board, which ensures the seal tightly sealing seal, When the valve opens, silk, under the action of will board in the spare, medium inside the circulation through unimpeded.Five, loading and unloading equipment instructions1 after unpacking equipment should be carefully read instructions.2 before lifting equipment, discharge the retaining bolt.Six, equipment installation1 before installation, should inspect equipment parts, pay attention to whether have damage, or whether the fasteners, loose.2 the flow direction of medium shown signs according to equipment and pipe connection and bolt fastening bolts.Seven, equipment maintenance1. According to open and close the valve, the frequency to the transmission parts regularly scrub, refueling.2 check valve using three months after the packing gland sealing condition, such as the leak, should tighten packing gland bolts evenly.3 should check whether fasteners.Add: inserts installation drawing trap.
