Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of sealing three-way switch valve.
Background technique
Three-way switch valve is widely used in metallurgy, petrochemical industry, and the execute-in-place of the industries such as environmental protection or distant control, be specially adapted in RECOVERY OF CONVERTER GAS device, control the recovery of coal gas and diffuse.Traditional three-way switch valve, in heat recovery and coal gas, natural gas transport application process, often need to be made high-temperature gas the switching of two directions, and bad to the adaptability of high temperature, sealability is poor, easily causes potential safety hazard.
Model utility content
Goal of the invention: the purpose of this utility model is to provide a kind of sealing three-way switch valve, improves the adaptive while to high-temperature gas, and sealability is better, stable.
Technological scheme: for realizing above-mentioned model utility object, the technical solution adopted in the utility model is:
A kind of sealing three-way switch valve, comprise valve body, sealed cylinder, movable valve plate, fork, main shaft, key, rolling bearing units, the arm of force, bearing pin, oil hydraulic cylinder and cover plate, on described valve body, be provided with an intake grill and two sealed cylinders, in the inside of valve body, be provided with movable valve plate, movable valve plate is connected with fork, fork is arranged on main shaft by key, and main shaft arranges on the cover board by rolling bearing units, and cover plate is arranged on the bottom of valve body; Both sides at described valve body are equipped with oil hydraulic cylinder, and oil hydraulic cylinder is connected with bearing pin, and bearing pin is connected with the arm of force, and the arm of force is connected respectively with the two ends of main shaft.
Both sides at described valve body are also provided with observation panel, and observation panel is bolted on valve body.
The two ends of described main shaft are connected with the arm of force by bolt.
Described oil hydraulic cylinder is arranged on the both sides of valve body by support.
In the periphery of described valve body, be provided with LIFT.
Beneficial effect: compared with prior art, sealing three-way switch valve of the present utility model is not only high temperature resistant, wear-resistant, rational in infrastructure, can extend life of valve, and sealability is fine, is easy to maintenance and safeguards, suitablely in producing running, apply, there is good practicability.

Fig. 2 seals the A of three-way switch valve to view.
embodiment,
Below in conjunction with accompanying drawing, technical solutions of the utility model are described, but protection domain of the present utility model is not limited to described embodiment.
As depicted in figs. 1 and 2, sealing three-way switch valve, comprise valve body 1, sealed cylinder 3, movable valve plate 4, fork 5, main shaft 6, key 7, rolling bearing units 8, the arm of force 9, bearing pin 12, oil hydraulic cylinder 13 and cover plate 15, on valve body 1, be provided with an intake grill and two sealed cylinders 3, in the inside of valve body 1, be provided with movable valve plate 4, movable valve plate 4 is connected with fork 5, and fork 5 is arranged on main shaft 6 by key 7, main shaft 6 is arranged on cover plate 15 by rolling bearing units 8, and cover plate 15 is arranged on the bottom of valve body 1; In the both sides of valve body 1, be equipped with oil hydraulic cylinder 13, oil hydraulic cylinder 13 is connected with bearing pin 12, and bearing pin 12 is connected with the arm of force 9, and the arm of force 9 is connected respectively with the two ends of main shaft 6.Both sides at valve body 1 are also provided with observation panel 11, and observation panel 11 is fixed on valve body by bolt 10.The two ends of main shaft 6 are connected with the arm of force 9 by bolt 10.In the periphery of valve body 1, be provided with LIFT 2.Oil hydraulic cylinder 13 is arranged on the both sides of valve body 1 by support 14.
Working procedure: the periphery at valve body 1 arranges LIFT 2, high temperature resistant, wear-resistant, movable valve plate 4 is connected with fork 5, fork 5 is arranged on main shaft 6 by key 7, main shaft 6 is arranged on cover plate 15 by rolling bearing units 8, can extract whole movable valve plate 4 out, keeps in repair very convenient; When three-way switch valve need to switch, oil hydraulic cylinder 13 promotes or pulls the arm of force 9, and then drives main shaft 6 to rotate, and drives fork 5 actions, and fork fluctuation activity valve plate 4 is done 90 ° of rotations, and movable valve plate 4 is switched between two air-flows of threeway are imported and exported.
Sealing three-way switch valve, not only high temperature resistant, wear-resistant, rational in infrastructure, can extend life of valve, and sealability is fine, be easy to maintenance and safeguard, suitablely in producing running, apply, there is good practicability.
