Description
Technical field
The present invention relates to a kind of outward opening mushroom ventilator.
Background technology
Along with the adding of Chinese World Trade Organization, international trade is increased, and the thing followed is the prosperity of shipping business and shipbuilding industry, and in order to guarantee the maximization of single navigation freight volume, all kinds of ships are also just made huger and huger.But no matter ship is made to such an extent that have muchly, and the ventilating system of one of them can not be ignored all the time, because it is related to crewman's the normal life and the normal operation of various power set.Because the particularity of ship's navigation situation, the boats and ships of international airline particularly, can run into various complexity, atrocious weather, if adopt the open type ventilator, even the ventilator of civil buildings, entering of rainwater or seawater all taken place inevitably, cause the corrosion of air pipeline, What is more can cause the damage of blower fan.So need a kind of ventilator, can avoid entering of rainwater or foreign material (comprising muroid and insects) under the normal condition, can also close rapidly under the abominable situation.
Summary of the invention
In order to address the above problem, the invention provides a kind of outward opening mushroom ventilator, both can prevent entering of mouse and insect, can prevent entering of rainwater and seawater again, simultaneously ventilating system close and abominable condition all over the world under, can quick closedown, have good looking appearance, easy to operate, distinguishing feature such as sealing is good.
The present invention has adopted following technical scheme: a kind of outward opening mushroom ventilator, it is made up of air duct, blast cap, weather proof cover and lift-bolt, in blast cap, be provided with stiffener, air duct and blast cap connect as one by bolt and nut, described weather proof cover is positioned at blast cap, be provided with guide plate on weather proof cover, described guide plate and stiffener are slidingly connected; Link to each other with air duct after described lift-bolt one end passes blast cap, weather proof cover successively, be provided with handwheel at the lift-bolt other end, also be provided with the locking back-up ring on lift-bolt, described locking back-up ring is located at blast cap and weather proof cover between the two.
Described air duct and blast cap joint are provided with otic placode, and the protection against rodents fly net is fixed on the otic placode; Be provided with support in the described air duct, be provided with bearing holder (housing, cover) on support, lift-bolt is fixed on the bearing holder (housing, cover) after passing blast cap, weather proof cover; Described blast cap is provided with bearing holder (housing, cover), and weather proof cover is provided with bearing block, and lift-bolt links to each other with air duct after passing bearing holder (housing, cover) and bearing block successively; Described blast cap is provided with the indicating arm cover, and indicating arm stretches into indicating arm cover back and links to each other with weather proof cover; The gap location of described weather proof cover and guide plate is provided with sealing gasket; The outside of described blast cap is provided with hanger.
The present invention has following beneficial effect: the present invention is applicable to the ventilating system of any building, be specially adapted to the ventilating system in each cabin of boats and ships, when avoiding that stormy waves and rainwater are serious under the bad weather, seawater and rainwater enter ventilating system, simultaneously special protection against rodents fly net, has effective protection against rodents insect protected function, and intensity highly corrosion resistant, easy weather proof cover lifting device, distinguishing feature with flexible operation and good seal, agent structure of the present invention are that the welding manner that adopts is processed, and the miscellaneous part engine lathe can be processed, has low cost of manufacture, the advantage that structural strength is high.
