Abstract
A silencing and ventilating mechanism for the sealed cabin is composed of external cylinder, perforated isolating plate, perforated plate for closure head, air-inlet closure plate, air inlet tube, perforated plate for the closure head of internal pipe, hollow jointer with external spiral threads, manual ball valve and the crewed jointer for rubber tube.
Description
(1) technical field
The present invention relates to a kind of noise reduction ventilation unit, particularly relate to a kind of silencing and ventilation apparatus for sealed ship's space.
(2) background technology
In products such as boats and ships, container, there are many closed in space, in closed in space, need to weld, work such as application, because the closed in space space is narrow and small, minimum has only 0.3m
3, the poisonous and harmful smog that discharges in welding or the coating process, gas, dust etc. fill the air whole cabin.Though the constructor wears certain labour protection protector, also be difficult to stand, adopt traditional small-sized explosion-proof fan or compress wind sebific duct to ventilate usually.Because little, the distance of hatch, noise is big, the wind sense is not soft, does not reach the effect of improving the local space environment.The constructor is endangered greatly, and production efficiency is low, so need a kind ofly under the small space condition, can guarantee construction safety, low noise, the silencing and ventilation apparatus for sealed ship's space that drafting efficiency is high.
(3) summary of the invention
The technical problem to be solved in the present invention provides the low noise ventilation unit that a kind ofly welds at airtight small space, can guarantee safety and production efficiency during operation such as application.
The technical scheme that adopts is:
Silencing and ventilation apparatus for sealed ship's space comprises urceolus, every sub-orifice plate, end socket orifice plate, air inlet shrouding, air inlet pipe, interior channel closure orifice plate, hollow male connection, manual ball valve, sebific duct nipple.Urceolus is a cylindrical structure, interior channel closure orifice plate is welded on an end of air inlet pipe, the hollow male connection is welded on the another port of air inlet pipe, be welded between air inlet pipe and the urceolus every sub-orifice plate, form a noise reduction every daughter board, the end socket orifice plate is welded on an end of urceolus, the air inlet shrouding is welded on the other end of urceolus, manual ball valve is connected on the hollow coupling screw thread, and the sebific duct nipple is connected on the manual ball valve, has constituted silencing and ventilation apparatus for sealed ship's space.
Above-mentioned urceolus, be drilled with a plurality of eyelets every sub-orifice plate, end socket orifice plate;
Above-mentioned air inlet pipe, interior channel closure orifice plate are drilled with a plurality of eyelets;
On above-mentioned hollow male connection, the sebific duct nipple machining screw is arranged.
Noise reduction of the present invention has solved the big problem of ventilation process noise every daughter board, rationally evenly the eyelet of layout has solved the not soft problem of wind sense, has reduced the concentration of the smog in the cabin, gas, dust, has improved the local space environment, increase constructor's the sense of security, improved operating efficiency.
(4) description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present invention.
(5) specific embodiment
Embodiment
Silencing and ventilation apparatus for sealed ship's space comprises urceolus 1, a plurality of every sub-orifice plate 2, end socket orifice plate 3, air inlet shrouding 4, air inlet pipe 5, interior channel closure orifice plate 6, hollow male connection 7, manual ball valve 8, sebific duct nipple 9.A plurality of passages 10 are arranged on the urceolus 1, a plurality of passages 11 are arranged on the air inlet pipe 5, air inlet pipe 5 is arranged in the urceolus 1.
Interior channel closure orifice plate 6 and hollow male connection 7 are welded on air inlet pipe 5 two ends respectively, form complete air inlet pipe; A plurality ofly be vertically welded in respectively on urceolus 1 and the air inlet pipe 5 every sub-orifice plate 2; End socket orifice plate 3 and air inlet shrouding 4 are welded on urceolus 1 two ends respectively, form the noise reduction ventilation unit; The noise reduction ventilation unit is after zinc-plated, and manual ball valve 8 is by being threaded in the hollow male connection 7, and sebific duct nipple 9 is installed on the manual ball valve 8, constitutes silencing and ventilation apparatus for sealed ship's space.
During use, silencing and ventilation apparatus for sealed ship's space is placed correct position in the cabin, compressed air wind regime sebific duct is connected with sebific duct nipple 9, opens manual ball valve 8, blast is transferred to appropriate level promptly opens.After construction finishes, compressed air wind regime sebific duct and sebific duct nipple 9 are disconnected, take out out of my cabin.
