Abstract
Model utility relates to a kind of flute check valve, comprise valve body, valve body is provided with suction port connecting end and air outlet connecting end, manhole is provided with in valve body, valve is provided with in through hole, valve body external frame is square, valve body external frame surrounding is provided with the bolt arrangement in order to fixed valve body, through-hole wall is provided with back-up ring, valve by rotating shaft and described back-up ring hinged, rotating shaft is located at above through hole horizontal center line apart from horizontal center line 1/2 through hole radius, it is characterized in that: described valve flange is provided with some square protrusions, described protrusion inside is provided with magnet thin slice, described manhole diameter is greater than diameter valve, annular ring is provided with between described manhole and described valve, annular ring and described valve body shaping.The utility model, by the square flat thin magnet protruding the inside and be provided with on valve, utilizes the suction iron principle of magnet, is adsorbed on iron annular ring, thus when realizing there is natural airflow in outdoor, valve also can not rock back and forth, avoids noise pollution.
Description
Technical field
The utility model relates to technical field of living goods, particularly relates to a kind of flute check valve.
Background technique
In daily life, flute check valve is one of kitchen discharged lampblack device of air accessory, traditional flue safety check, under range hood is in running order, be under the airflow function that the air door of safety check is carried at range hood and open, and range hood is not when working, valve on safety check will utilize gravity naturally to fall to closing, but, when there is normal cross-ventilation outdoor, the frequent malfunction of easy formation valve, send the noise of " bang bang ", for this phenomenon, study a kind of flute check valve that can overcome this phenomenon, there is important practical significance.
Model utility content
The purpose of this utility model is to provide a kind of flute check valve.
The technical solution of the utility model is: a kind of flute check valve, comprise valve body, valve body is provided with suction port connecting end and air outlet connecting end, manhole is provided with in valve body, valve is provided with in through hole, valve body external frame is square, valve body external frame surrounding is provided with the bolt arrangement in order to fixed valve body, through-hole wall is provided with back-up ring, valve by rotating shaft and described back-up ring hinged, rotating shaft is located at above through hole horizontal center line apart from horizontal center line 1/2 through hole radius, it is characterized in that: described valve flange is provided with some square protrusions, described protrusion inside is provided with magnet thin slice, described manhole diameter is greater than diameter valve, annular ring is provided with between described manhole and described valve, annular ring and described valve body shaping.
Further, annular ring material is iron.
Further, described square protrusion 4, is symmetrically distributed in valve both sides by the vertical central shaft of valve.
The beneficial effects of the utility model are:
A kind of flute check valve, protrude by square on valve and be provided with flat thin magnet, utilize the suction iron principle of magnet, the annular ring between manhole and valve is set to irony, thus when realizing there is natural airflow in outdoor, valve also can not rock back and forth, avoids noise pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is generalized section of the present utility model.
Wherein: 1, valve body 2, suction port connecting end 3, air outlet connecting end 4, manhole
5, valve 6, bolt arrangement 7, back-up ring 8, rotating shaft
9, protrusion 10, magnet thin slice 11, annular ring
Embodiment
Below in conjunction with accompanying drawing, brief description is made to embodiment of the present utility model.
A kind of flute check valve as shown in Figure 1, comprise valve body 1, valve body 1 is provided with suction port connecting end 2 and air outlet connecting end 3, manhole 4 is provided with in valve body 1, valve 5 is provided with in through hole 4, valve body 1 external frame is square, valve body 1 external frame surrounding is provided with the bolt arrangement 6 in order to fixed valve body 1, through hole 4 inwall is provided with back-up ring 7, valve 5 is hinged by rotating shaft 8 and described back-up ring 7, rotating shaft 8 is located at above through hole 4 horizontal center line apart from horizontal center line 1/2 through hole 4 radius, it is characterized in that: described valve 5 edge is provided with some square protrusions 9, described square protrusion 9 is 4, valve 5 both sides are symmetrically distributed in by the vertical central shaft of valve 5, described protrusion 9 inside is provided with magnet thin slice 10, described manhole 4 diameter is greater than valve 5 diameter, annular ring 11 is provided with between described manhole 4 and described valve 5, annular ring 11 is one-body molded with described valve body 1, annular ring 11 material is iron.
Working method: when user uses range hood, flute check valve is opened and is started working under airflow function, after having fried dish closedown range hood, flute check valve falls after rise under gravity, and inhaling iron thin slice can hold iron annular ring, fixes valve, even if there is natural airflow outdoor, also can not easily valve open, and air-flow when working is enough to valve open, makes valve working.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
