Abstract
The invention discloses an automatic closing device of an air pipe head, which comprises a main body with a connecting flange and an air passage, and a cap fixed on the main body, a floating ball in the cavity of the main body, and a sealing device and a protection device, which are located above the floating ball, wherein the integral outline of the main body and the cap is a cylindrical cup shape, and the other components are arranged in the main body. The product of the invention is made from full aluminum alloy material, and has the advantages of reasonable structure, high reliability, long practical period, esthetic appearance, light weight, convenience in disassembly and low cost. The product can fully guarantee the air circulation in a cabin.
Description
Technical field
The present invention relates to a kind of air pipe head self closing device, refer in particular to a kind of marine air pipe head self closing device.
Background technology
Air pipe head self closing device radical function is as usefulness ventilated in the confined chambers such as cabin.According to its purposes, this device must keep the inside and outside airiness of tube head, will guarantee simultaneously when boats and ships tilt or run into stormy waves, can play the effect of automatic closed channel.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, pontoon type cargo tank air pipe head, pontoon type water tank air pipe head, float-ball type oil, water tank air pipe head.Be applied to oil, the water tank air pipe 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 air by-pass passage body and fixing on it block, lay float at the lumen of body, the float type is a floating drum, floating cake or thin wall metal ball.The sealing element that above float, is provided with, 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 object of the invention 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.
Technical scheme of the present invention is: comprise the body that has butt flange and air by-pass passage and fixing on it block, at the ball float of body lumen and the sealing arrangement above ball float, protective device; The appearance integral of said body and block is the cylinder cup-shaped, and other parts place in the body.
The double-layer hollow cylindrical shell that said body is made up of outer wall circle and inwall circle, body is used bolt with block, and its complementary space is an air by-pass passage.
Described ball float is positioned at the lumen of body, is provided with along the air discharge port of reinforced rib symmetry at lumen.
Described sealing arrangement is mounted in the seal ring of bodies top.
Be coated with flame screen on the said seal ring, flame screen is fixed on bodies top with two fixation clips.
Said ball float is the plastic hollow ball.
Described air pipe head self closing device is used all aluminium alloy made, and is rational in infrastructure, and unfailing performance is high, and the practical cycle is long, and outward appearance is graceful, and is in light weight, convenient disassembly, and cost is low.
Device of the present invention is mainly used in cargo tank, the water tank airline that boats and ships, offshore platform are used.Radical function is the airiness that guarantees in the cabin.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further specified.
Fig. 1 is a structure cutaway view of the present invention.
The specific embodiment
As shown in Figure 1; Major part of the present invention is a body 1, and body 1 is that all aluminium alloy material is processed, and places a ball float 9 at the cavity place of the centre of 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 get into, the ball float 9 automatic closed vent mouth that can in cavity, float.
Said block 2 is fixed on the body 1 through 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 butt flange, and air gets in the cavity of body 1 thus, and other parts all are built in this body.
The double-layer hollow that the base portion 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 discharge port 10 of reinforced rib 11 symmetries at body 1 cavity place.
As shown in Figure 1, sealing arrangement is mounted in the seal ring 5 of body 1 end face, on seal ring 5, is coated with flame screen 3.
