Description
Technical field
The utility model relates to emission-control equipment field, particularly relates to a kind of lifting type bacterial type valve on waste gas combustion furnace.
Background technique
Waste gas combustion furnace is a visual plant in the treatment process production procedure such as industrial production and car industry Painting Shop, be used to steam mixture Thorough combustion in stove of volatile organic compound (toluene, dimethylbenzene etc.), making toxic substance change into nontoxic flue gas is thrown in air, reaches the standard-required of country to toxic emission.
The wind direction switching valve of current most domestic two Room, three Room ceramic heat-storing formula waste gas combustion furnaces (being called for short RTO) all adopts butterfly valve, or three-dimensional switching valve, can fit not tight with air port in the process that wind direction switches, cause the leakage of organic exhaust gas, and very large noise can be produced.Ye You producer adopts horizontal bacterial type valve, and lifting type bacterial type valve of the prior art, in use, there will be following problem:
1, valve body left and right horizontal moves closed air door, but sinking situation can occur valve body of long duration, makes air port airtight tight, causes leakage;
2, current lifting type bacterial type valve all lacks guide function, and lifting type valve easily occurs along axis rotation, although can not as horizontal air-valve bias large, namely the skew of a wee bit can cause Leakage Gas.
Model utility content
The utility model is in order to overcome deficiency of the prior art, provide a kind of lifting type bacterial type valve, this bacterial type valve is that the hemispherical air-valve of mushroom is larger owing to conducting oneself with dignity, to be seated on air door and can to combine closely No leakage with air door, add guide function and seal ring simultaneously, improve exhaust treatment efficiency, and greatly reduce noise when wind direction switches.
The utility model is achieved through the following technical solutions:
Lifting type bacterial type valve, comprises bacterial type valve body, connecting rod, cylinder, and described bacterial type valve body is mushroom hemisphere face, and what valve body occurred in the case of a high temperature expands with heat and contract with cold and can compensate absorption by spherical surface, can not deform; The upper end of described connecting rod connects bacterial type valve body, is connected with cylinder in the lower end of connecting rod; The edge joint weld of described bacterial type valve body is connected to cutting plate, described cutting plate totally two pieces, and the other end of cutting plate is positioned at the side of guide rod and is not connected with guide rod, wherein, cutting plate does not weld with guide rod, can reduce the two resistance brought that mutually rubs, valve body is more prone to; Described guide rod is used for the movement locus of fixing bacterial type valve body; Described bacterial type valve body is provided with seal ring with the air port place of combining.
As optimal technical scheme of the present utility model, in the groove of described seal ring between bacterial type valve body second sphere and air port, and be fixed by screws in groove, the upper-end surface contact of seal ring is on second sphere of bacterial type valve body, seal ring adopts ceramic fiber, there is certain elasticity, make bacterium valve drop on surface of contact on seal ring so larger, better tightness and noise is less.
As optimal technical scheme of the present utility model, described guide rod is pipe or square tube, and guide rod is fixed on the side in air port, and its length exceedes the stroke of bacterial type valve body.
Compared with prior art, the beneficial effects of the utility model are:
1, by being provided with guide rod, if rotation situation appears in bacterial type valve body, then cutting plate contact guide rod, stops bacterial type valve body to be rotated further, ensure that the movement locus of bacterial type valve body, thus ensure that the closed situation in bacterial type valve body and air port;
2, be provided with seal ring by being provided with seal ring at bacterial type valve body with the air port place of combining, make valve body and air port tight close on the one hand, No leakage, improves exhaust treatment efficiency, greatly reduces noise when wind direction switches on the other hand.
