Abstract
The utility model relates to a sealing device of a non-stop air door on an exhaust port of an oil fume pump machine, which comprises an air door 1 and an air door base 2. The sealing device is fixed and arranged between a discharge pipe 3 and a flue 4. Because the utility model improves the contact form between the air door and the base in the structure, the circumfluence of gas molecules is effectively prevented. Meanwhile, a sealed ring provided by the utility model does not increase pressure on the non-stop blade area much, and the oil fume pump machine can freely turn on blades. Simultaneously, because the utility model does not change the oil fume pump machine very much, cost is greatly reduced. Besides, the maintenance of the seal non-stop air door is simple, and the sealed non-stop air door is easy to be unpicked, washed and replaced. The sealing device has the advantages of simple structure, low cost and easy realization.

Background technology
In the prior art, in order to solve air exhauster, especially the problem of smoke exhaust ventilator wind-fall in use filling is provided with the non-return air door at the exhaust outlet place of family expenses smoke exhaust ventilator.Yet because contacting of air blade and base is the rigidity contact, promptly contacting between air door and the firm banking do not optimized, and when air door is returned, still has very big space between air door and base.Make the gas in the flue blow back into smoke exhaust ventilator, and then in the inlet chamber, cause room air pollution.
While is because the general structure of existing smoke exhaust ventilator is comparatively ripe and universal, if problems such as obviously can causing bigger cost budgeting and the checking of structure practicality is transformed in smoke exhaust ventilator inside, so the inventor is on the basis that does not change existing smoke exhaust ventilator general structure, just carry out structure of modification, solve the technical problem of above-mentioned existence at the part.
The utility model content
The utility model is not tight owing to the air door closure in order to solve in the prior art, causes the air-polluting technical problem, has developed the sealing device of a kind of smoke exhaust ventilator exhaust outlet place non-return air door, has solved the technical problem that existing smoke exhaust ventilator exists effectively.
The technical solution of the utility model is as follows:
The sealing device of the non-return air door at a kind of smoke exhaust ventilator exhaust outlet place comprises air door 1, air door base 2; Described sealing device is fixedly installed between discharge pipe 3 and the flue 4; Described sealing device comprises a hermetically-sealed construction, and described hermetically-sealed construction is arranged on the non-return air door 1, when being used for the 8 times seats of blade when described non-return air door 1 and air door base 2 airtight.
In order to solve airtight not tight technical problem in the prior art, described hermetically-sealed construction also is provided with a sealing ring 5 in the outer rim of described non-return air door 1, described sealing ring 5 closely is socketed on the outward flange of described non-return air door 1, and the non-return air door 1 and air door base 2 adaptive are as the criterion of the thickness of described sealing ring 5 to comprise sealing ring 5.
In order to make that contact is Elastic Contact between air door 1 and the base 2, improve closure effect, described sealing device also comprises a base hermetically-sealed construction, and described base hermetically-sealed construction is to comprise an air door base 2 and a base sealing ring 6 that is included on the described air door base 2;
The axial cross section of described air door base 2 is ' L ' type, and described base sealing ring 6 fits snugly on the horizontal platform of ' L ' type air door base 2, and the length of the horizontal platform of the thickness of described base sealing ring 6 and air door base 2 is suitable.
In concrete application, the size of described sealing ring 5 and base sealing ring 6 is decided by the diameter of smoke exhaust ventilator exhaust outlet and the diameter of flue, and the radical length scope of described sealing ring 5 is 5mm-15mm, is preferably 10mm; Thickness is 1mm-3mm, is preferably 2mm;
The radial extension of described base sealing ring 6 is 5mm-15mm, is preferably 10mm; Thickness is 1mm-4mm, is preferably 3mm.
In concrete application, the material of described non-return air door 1 is plastics or polyester; The material of described air door base 2 is a sheet metal
Described sealing ring 5 and base sealing ring 6 are sealed material, are oil resistant rubber or nylon.
The utility model makes that owing to the contact form that has structurally improved between air door and the base contact-making surface is an Elastic Contact, and the coefficient of friction of contact-making surface and seal enhancing, has effectively stoped the backflow of gas molecule.Simultaneously the setting of sealing ring is not bigger is increased in pressure on the non-return blade area, is convenient to the smoke pumping function and opens blade freely.Because the utility model does not carry out big change to smoke exhaust ventilator itself, greatly reduce cost simultaneously.In addition, sealing device is safeguarded simple, is convenient to unpick and wash and change.The utility model is simple in structure, and cost is low, is easy to realize.
