Abstract
The utility model relates to an eccentric type back valve, which comprises a base and a valve body. Both ends of the valve body are respectively provided with an air inlet and an air outlet. The utility model is characterized in that an eccentric valve plate is arranged on the air outlet, and the position of a rotating shaft of the eccentric valve plate is above the center of the air outlet. The utility model has the advantages of novel design and simple structure. The similar products are greatly improved, the problem of greater resistance of the existing concentrating draindown system when oil fume is exhausted is effectively solved, exhausted oil fume is effectively filtered, and waste oil content of exhausted gas is reduced. The eccentric type back valve is especially suited to be used for various fume exhausting systems.
Description
The utility model relates to a kind of check valve, and particularly a kind of residential housing kitchen flue gas is concentrated the eccentric check valve of releasing system.
At present, widely used cooker hood effective collection the oil smoke in the kitchen, discharge to outdoor corridor but the discharging of oil smoke is general direct, or broken wall causes Residential District Environment to pollute to the open air discharge, and damaged the attractive in appearance of building, for this reason, succeeded in developing a kind of residential housing fume centralized releasing system, it comprises check valve, concentrates outlet pipe, roof exhaust outlet, through promoting the use of, obtained good using effect.Yet, in actual use, the design of the check valve part of this fume centralized releasing system is also perfect not to the utmost, mainly show because the valve plate of traditional louvered check valve is opened deficiency, resistance is bigger when causing oil smoke discharge, discharge amount is reduced, influenced the working efficiency of fume centralized releasing system.
The purpose of this utility model provides the eccentric check valve that a kind of exhaust resistance is little, discharge amount is big.
Task of the present utility model is to realize like this.The utility model comprises base, valve body, is respectively equipped with intake grill and exhaust outlet in two ends of valve body, it is characterized in that: eccentric valve plate is housed on described exhaust outlet, and the position of eccentric valve plate rotating shaft is above the exhaust outlet center.
The utility model is novel, simple in structure, like product has been made significant improvement, can effectively solve the existing bigger problem of resistance when concentrating in the releasing system oil smoke discharge, and the oil smoke of being arranged carried out effective filtration, reduced the waste oil content of discharging gas, be particularly suitable for various flue gas emissions and use.
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
The utility model comprises base 1, valve body 2, is respectively equipped with intake grill 3 and exhaust outlet 4 at the two ends of valve body 2, it is characterized in that: eccentric valve plate 5 is housed on described exhaust outlet 4, and the position of eccentric valve plate 5 rotating shafts is above exhaust outlet 4 centers.Because valve plate 5 be eccentric the installation, it is less therefore to open the required blast of valve plate, and also less by the windage that valve plate caused when discharging, and has improved discharge efficiency effectively.The waste oil content in the smoke exhaust in order to reduce also is equipped with filter screen 6 on valve body 2 simultaneously, and oil smoke is carried out secondary filter.Described filter screen 6 is contained on the drawer plate 7, can easily filter screen be extracted out and change, cleans.
