Description

Marine air pipe head
Technical field
The present invention relates to a kind of boats and ships air pipe head.
Background technology
Air pipe head is as the indoor ventilative usefulness of cabin, according to its function, keep the inside and outside airiness of tube head, when boats and ships tilt and run into stormy waves, can play the effect of automatic closed channel simultaneously.At present the structure of the widely used marine air pipe head of China is: comprise the main body that has air by-pass passage and fix block on it, lay float at the lumen of main body that the float type is a floating drum, floating cake or thin wall metal ball.The sealing element that above float, is provided with, commonly used is face seal and arc surface sealing, and this air pipe head is when reality is used, and the problem of appearance has: (1) installs trouble, and the supporting consumptive material of agent structure is many, and design is heavy; (2) sealing effectiveness is bad, and float realizes that automatic sealing function is bad; (3) air extractor duct is the mouth of arbitrarily opening on main wall, is subjected to the influence of inside and outside air-flow can cause ventilative not smooth like this.
Summary of the invention
The objective of the invention is provides the light in structure letter, the reliable quality marine air pipe head in order to overcome the deficiencies in the prior art.
Technical scheme of the present invention is: comprise the main body that has butt flange and air by-pass passage and fix block on it, at the ball float of main body lumen and the sealing arrangement above ball float, protective device, the appearance integral of described main body and block is the cylinder cup-shaped, and other parts are built in the goblet fully;
The double-layer hollow cylindrical shell that described main body top is made up of outer wall circle and inwall circle, only the Internal and external cycle hollow position at the top is provided with the boss that is used for fixing main body and block, and main body middle part hollow position is provided with reinforced rib, and its complementary space all is an air by-pass passage;
Be provided with monosymmetric air discharge port at the middle part of described double-layer hollow cylindrical shell;
The starting end of described air discharge port be in the main body inner chamber from the bottom surface of reinforced rib along 45 ° of oblique derivation;
Described sealing arrangement is made up of seal ring that is installed in the main body end face and built-in wherein O RunddichtringO;
On described seal ring, buckle a protective cover, steady admittedly with gland;
Described ball float is the plastic hollow ball;
Described main body is a lightweight duralumin material, and protective cover is a metallic article.
The present invention breaks through the design concept of traditional product from structure, material, ventilative principle, and light, withstanding corrosion simple in structure on the whole, important is easy for installation, venting capability good, can fully guarantee waterproof, fire prevention, the insect protected of boats and ships under any working condition.
Description of drawings
Following structure the drawings and specific embodiments are described in further detail the present invention.
Fig. 1 is the revolved sectional view of E of the present invention-E direction;
Fig. 2 is the structure cutaway view of main body 1 among Fig. 1;
Fig. 3 is an A-A part sectional view among Fig. 2;
Fig. 4 is a B-B part sectional view among Fig. 2;
Fig. 5 is a C-C part sectional view among Fig. 2;
Fig. 6 is a D-D part sectional view among Fig. 2.
The specific embodiment:
As shown in Figure 1, vital parts of the present invention is a main body 1, main body 1 is a lightweight duralumin material, a ball float 9 is placed at cavity place in the centre of main body 1, ball float 9 is the plastic hollow ball, above ball float 9, sealing arrangement is set, when hull tilts to have water to enter, the ball float 9 automatic closed vent mouth that can in cavity, float.
Fixing block 8 on main body 1, main body 1 and 8 the appearance integral of blocking a shot are designed to the cylinder cup-shaped, and the center of cup footing is the DN latus rectum mouth 10 of butt flange, and air enters in the cavity of main body thus, and other parts of the present invention all are built in this goblet.
As Fig. 2~shown in Figure 6, the double-layer hollow cylindrical shell that the cup section of main body 1 is made up of outer wall circle 12 and inwall circle 13, only the Internal and external cycle hollow position at the top is provided with several boss 14 that is used for fixing main body 1 and block 8, and there have screw to be used for block 8 on boss 14 to be fixing.As shown in Figure 6, the present invention is symmetrical arranged 4 boss 14, and boss 14 stretches into the height of bottom only for fixing block 8, increases the airiness volume between Internal and external cycle as far as possible.As shown in Figure 4, be provided with reinforced rib 16, to guarantee the intensity of main body in the both sides of the middle part of main body 1 hollow position symmetry.Between the outer wall circle 12 and inwall circle 13 of main body 1, except boss 14 is provided with reinforced rib 15, to guarantee the intensity of main body.Between the outer wall circle 12 and inwall circle 13 of main body 1, except boss 14 and reinforced rib 15 occupy the space, its complementary space all is an airflow path.
Shown in Fig. 2,5, the middle part of the double-layer hollow cylindrical shell of forming at outer wall circle 12 and inwall circle 13 is provided with monosymmetric air discharge port 11, about two air discharge ports, 11 relative positions be 180 °, even inside and outside air-flow is inhomogeneous, can not influence permeability of the present invention yet.The starting end of air discharge port 11 be from main body 1 inner chamber at the bottom surface of reinforced rib 15 along 45 ° of oblique derivation, this structure design makes the smoothness of giving vent to anger.
As shown in Figure 1, 2, sealing arrangement is made up of seal ring 3 that is installed in main body 1 end face and built-in wherein O RunddichtringO 2, on seal ring 3, buckle protective device, it is the netted protective cover 7 of a metallic article, with gland 5 solid steady protective covers 7, gland 5 is fixing with inwall circle 13 with bolt 4 and packing ring 6 simultaneously.
Structure as shown in Figure 2, main body 1 be by lightweight duralumin material by the mould one-shot forming, comprise boss 14 and reinforced rib 15.
