Description
Technical field
The present invention relates to hood technical field of sealing technology, especially a kind of hood conical surface sealing structure.
Background technology
Hood is an important component of the systems such as dust removal by ventilation, cleaning harmful gas, high-temperature gas exclusion.It is logical
The range that wind hood is related to is very extensive, the every profession and trades such as metallurgy, mine, machinery, chemical industry, building materials, medicine, health, each department
All need setting vented exhaust cover.
But the exhaust cover body and discharge duct of existing hood are an integral structure mostly, are integrally formed, leakproofness
Can be good, but when independent discharge duct damages or pollution needs replacing, this non-removable connection structure so that need
It is replaced with together with intact exhaust cover body, causes the unnecessary wasting of resources, but be when being vented between cover body and discharge duct
When detachable structure, sealing performance cannot be guaranteed again.
Therefore it provides a kind of dismountable and good seal performance hood conical surface sealing structure is current this field skill
The problem of art personnel's urgent need to resolve.
Invention content
The purpose of the present invention is：A kind of hood conical surface sealing structure is provided, exhaust cover body and discharge duct are realized
It is detachably connected, is easy to individually replace exhaust cover body or discharge duct, also, good seal performance.
To achieve the goals above, the technical solution adopted by the present invention is as follows：
A kind of hood conical surface sealing structure, including exhaust cover body and discharge duct, the exhaust cover body and the exhaust
Pipeline connects, and conical surface seal portion is additionally provided between the exhaust cover body and the discharge duct, the conical surface seal portion includes
Rubber seal, conical surface set, washer and clamp nut；The rubber seal is set on the discharge duct, the rubber
The both sides of sealing ring are covered with the conical surface respectively to be connected, and sealing surface is formed in the upper close discharge duct side of conical surface set
With first conical surface, it is interval trough between the conical surface set and the discharge duct, the washer, institute is placed in the interval trough
Washer and first taper-face contact are stated, the clamp nut, the bottom end of the clamp nut have also been plugged together in the interval trough
With the washer contacts.
Preferably, conical surface set inside is equipped with screw thread, and the inside is the side contacted with the clamp nut.
Preferably, the conical surface put on close to the exhaust cover body side be second conical surface, second conical surface with it is described
The conical surface for being vented cover body is corresponding.
Preferably, the horizontal plane for extending top and being higher than the conical surface set upper side of the clamp nut.
Preferably, the rubber seal is O-shaped rubber seal.
By taking above scheme, the beneficial effects of the invention are as follows：
It is whole by the conical surface seal portion being made of rubber seal, conical surface set, washer and clamp nut, it is mounted on exhaust
Between cover body and discharge duct, rubber seal coordinates with discharge duct, and the conical surface covers the cone of upper second conical surface and exhaust cover body
Face coordinates, good integrity, stable structure；When screwing clamp nut, the bottom end meeting extruded gasket of clamp nut, in first conical surface
Under the action of, it is pressed down against rubber seal, rubber seal is close to discharge duct and sealing surface simultaneously, in this way, not only real
Being detachably connected between exhaust cover body and discharge duct is showed, has been easily changed, and form annular sealing strip, greatly improves
The reliability of sealing, sealing performance are excellent.
Description of the drawings
Fig. 1 is a kind of overall structure sectional view of hood conical surface sealing structure of the present invention.
In figure：1- is vented cover body, 2- discharge ducts, 3- conical surface sets, 4- washers, 5- clamp nuts, 6- sealing surfaces, 7-
First conical surface, second conical surfaces of 8-.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
