The valve rod 4 arranged in the gate valve is connected with a sheet type valve plate 2; the two sides of the valve plate 2 are provided with an inner valve side plate 3 and a valve body 1; the inner valve side plate 3 is provided with a sealing opening; the two ends of the valve plate 2 are provided with sealing openings correspondingly; one end of the valve plate 2 is connected with a material feeding pipe, the other end is connected with a discharge pipe; the lower end of a material outlet of the valve body 1 is provided with a material cleaning notch C which is straight with the discharge pipe; a cylinder material feeding box 11 is arranged at the lower end of a lower flange cylinder cover 12 of the cylinder 15 connected with the bracket 9; a material feeding box 10 is arranged at the joint position of the lower end of the bracket 9 and the gate valve; the utility model has the advantages of reasonable structure, small size, light weight, pressure resistance and safe, good sealing performance, corrosion resistance and long service life, which can also used for non solid materials, such as vapor in airs, acid and alkali liquid in liquids, coal in solids, foods and cement mortar.
Description
Affiliated technical field
The utility model belongs to valve type, the pneumatic quick open type gate valve of solid slag that particularly a kind of chemical industry is used.
Background technique
At present, the pneumatic brake plate valve that chemical industry is used adopts the bilateral valve port sealing structure, be provided with the sealing valve port in valve port material feeding mouth one side, be provided with the sealing valve port again, be divided into upper and lower two bodies in discharge port one side, top is valve cover structure, and the bottom is a valve body structure, after valve has been arranged solid slag, between the valve body two bottom sides valve port of gate valve, still retain the part slag charge, be obstructed when valve plate is moved down, can not seal valve port, make valve port gas leakage, water and slag charge, influence manufacturing operation, cause economic loss.
Summary of the invention
The purpose of this utility model is to overcome above technical deficiency, provides a kind of and opens soon, the pneumatic quick open type gate valve of solid slag of good seal.
Task of the present utility model is, the pneumatic quick open type gate valve of solid slag, have piston is installed in cylinder block, the gate valve that valve rod connects through support, the gate valve inner valve stem connects the chip valve plate, internal valve side plate and valve body are installed in the valve plate both sides, sealed mouth is installed at valve side plate place, the two ends correspondence is provided with sealed mouth at the valve plate place, one end connects supply pipe, the other end connects drainage conduit, valve body discharge port lower end is provided with expects that clearly breach is mutually straight with drainage conduit, the cylinder stuffing box is installed in the lower flange cylinder cap lower end of the cylinder block that support connects, and stuffing box is installed in support lower end and gate valve joint.
The pneumatic quick open type gate valve of solid slag, flashboard valve is formed housing in the flashboard both sides by valve side plate and valve body, and a side is the valve side plate, and opposite side is a valve body, establish sealed mouth at the valve side plate, under the pressure of valve rod, make valve plate press valve body, have thrust function, guarantee sealing, be provided with bottom valve body and expect breach clearly, prevent to leave over slag charge, valve closing is tight.
Description of drawings
Fig. 1 shows the pneumatic quick open type gate valve of solid slag structure.
The B-B sectional view of Fig. 2 diagrammatic sketch 1.
The A of Fig. 3 diagrammatic sketch 2 is to view.
Among the figure, the 1-valve body; The 2-valve plate; 3-valve side plate; The 4-valve rod; The 5-bolt hole; The 6-bolt; The 7-bolt; The 8-support bracket bolt; The 9-support; The 10-stuffing box; 11-cylinder stuffing box; 12-cylinder lower flange cylinder cap; The 13-cylinder piston; 14-close ring alive; The 15-cylinder block; The 16-bolt; The 17-cylinder block; The 18-sealing gasket; The short stud bolt of 19-; C-expects breach clearly
Embodiment
With reference to accompanying drawing 1,2,3, the pneumatic quick open type gate valve of solid slag, left and right sides plate constitutes valve housing, one side is that valve body 1, opposite side are that valve side plate 3 inboards are provided with the sealed mouth sealing, sealed mouth bottom, valve body 1 outside is provided with expects breach C clearly, and the clear material breach C of valve body 1 discharge port bottom is mutually straight with the drainage conduit inwall, and solid slag is washed away by air-flow, the noresidue slag charge, so valve is closed tight.Inlet hole b by the lower flange cylinder cap 12 of cylinder block 15 enters when pressurized air, the exhaust port a exhausting air of cylinder top cover 17, piston 13 moves to the cylinder top under the compressed-air actuated promotion, move on actuate valve stem 4, the valve plate 2 simultaneously, open fast, opening the solid slag of late gate inlet side discharges under the promotion of gas pressure fast, after solid slag is got rid of, because the clear material breach C bottom of valve bottom outlet side is mutually straight with the discharge tube bottom surface, under the purging of dispatch gas or liquid, do not have the residual solid slag charge at the bottom of the valve, when valve closing, can close tight.Closing of valve, pressurized air enters cylinder block 15 tops, relief opening b exhaust at the bottom of the valve by cylinder top cover 17 suction port a lid, cylinder piston 13 promotes valve rod 4, valve plate 2 moves down valve is closed tight, and behind the valve closing, cylinder head pressure does not still subtract, keep-up pressure, make valve be in closed condition.
The pneumatic quick open type gate valve of solid slag, simple, little, in light weight, the withstand voltage safety of volume rational in infrastructure, good, corrosion-resistant, the long service life of sealing, also can be used for non-solid material, as: air kind steam, liquid kind acid ﹠ alkali liquid, solid kind coal, food, cement mortar etc.
