Abstract
The utility model discloses an air pipe head closing device, which comprises a body with a connecting flange and an air passage, a cap fixed to the body, a float ball in a middle cavity of the body, a seal device and a protective device. The seal device and the protective device are arranged above the float ball. The body and the cap are both in cylindrical shapes, while other parts are disposed in the body. The air pipe head closing device is made of all-aluminum alloy materials, reasonable in structure, high in reliability, long in service cycle, attractive in appearance, light in weight, convenient to disassemble and low in cost, and interior ventilation of a cabin can be fully guaranteed.
Description
Technical field
The utility model relates to a kind of air pipe head self closing device, refers in particular to a kind of marine air pipe head self closing device.
Background technology
Air pipe head self closing device major function is as usefulness ventilated in the confined chambers such as cabin.According to its purposes, this device must keep the inside and outside circulation of air of tube head, will guarantee simultaneously can play the effect of automatic closed channel when boats and ships tilt or run into stormy waves.The pattern regulation of air pipe head has: hat type air pipe head, gooseneck type air pipe head, the double ventilative air pipe head of depth measurement, float-type cargo tank air pipe head, float-type water tank air pipe head, float-ball type oil, water tank air pipe head.Be applied to oil, the water tank air hose upper end of boats and ships respectively according to its 26S Proteasome Structure and Function.
The structure of present widely used marine air pipe head is: have the body of air duct and fix block on it, lay float at the lumen of body, the float type is a floating drum, floating cake or thin wall metal ball.The seal member that is provided with above float, this air pipe head are when reality is used, and existence is installed trouble, designed heavy, shortcomings such as sealing effectiveness is bad, it is smooth to breathe freely, not environmental protection of material.
Summary of the invention
The utility model purpose be to provide a kind of rational in infrastructure, unfailing performance is high, the practical cycle is long, outward appearance is graceful, the marine air pipe head self closing device of in light weight, convenient disassembly.
The technical solution of the utility model is: comprise the body that has adpting flange and air duct and fix block on it, at the ball float of body lumen and the sealing device above ball float, protector, the appearance integral of described body and block is the cylinder cup-shaped, and other parts place in the body.
The double-layer hollow cylindrical shell that described body is made up of outer wall circle and inwall circle, body is used bolting with block, and its complementary space is an air duct.
Described ball float is positioned at the lumen of body, is provided with along the air outlet slit of reinforcement symmetry at lumen.
Described sealing device is mounted in the sealing ring of bodies top.
Be coated with flame screen on the described sealing ring, flame screen is fixed on bodies top with two fixation clips.
Described ball float is the plastic hollow ball.
Described air pipe head self closing device is used the manufacturing of all aluminium alloy material, and is rational in infrastructure, the unfailing performance height, and the practical cycle is long, and the outward appearance grace is in light weight, convenient disassembly, cost is low.
Device described in the utility model is mainly used in cargo tank, the water tank air pipe line that boats and ships, offshore platform are used.Major function is the circulation of air that guarantees in the cabin.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is a structure cutaway view of the present utility model.
The specific embodiment
As shown in Figure 1, critical piece of the present utility model is a body 1, body 1 is that all aluminium alloy material is made, a ball float 9 is placed at cavity place in the centre of body 1, ball float 9 is the plastic hollow ball, above ball float 9, sealing device is set, when hull tilts to have water to enter, the ball float 9 automatic closed vent mouth that can in cavity, float.
Described block 2 is fixed on the body 1 by 3 bolts 8, and body 1 and 2 the appearance integral of blocking a shot are designed to the cylinder cup-shaped, and the center of cup footing is the latus rectum mouth 12 of adpting flange, and air enters in the cavity of body 1 thus, and other parts all are built in this body.
The double-layer hollow that the main part of described body 1 is made up of inwall circle 6 and outer wall circle 7 is simplified, is air communication channel between the inwall circle 6 of body 1 and the outer wall circle 7.
As shown in Figure 1, be provided with along the air outlet slit 10 of reinforcement 11 symmetries at body 1 cavity place.
As shown in Figure 1, sealing device is mounted in the sealing ring 5 of body 1 end face, is coated with flame screen 3 on sealing ring 5.
