Description
Technical field
The present invention relates to cattle carrier fence area ventilating systems, more specifically to a kind of loop type of PVC air hoses
Connection structure.
Background technology
Traditional cattle carrier totally enclosed type fence area, the life excretion activity of fence area internal cause animal, fence area inner ring
There is great corrosivity to be therefore proposed requirement for anticorrosion for a variety of materials used in fence area in border.Conventional air hose is equal
It is zinc-plated using stainless steel or carbon steel surface, since fence area air hose specification is big, total laying length grows (about 6000 meters of total length), such as
Using conventional material, ship weight will be caused to greatly increase, reprinting ability is reduced to have to reduce fence area.And if
Common air hose is substituted using conventional pvc pipe peculiar to vessel, price can be sufficiently expensive, and in addition conventional pvc pipe peculiar to vessel uses casing connection, set
Glue special fixed bonding is used between pipe and pipe, it is great in constructing amount and do not have adjustability, and our cattle carrier encloses
Column plot structure uses special elastic connection form, during actual use, air hose may connect flexible because of structural elasticity
And it destroys.
Invention content
The present invention reduces construction operation amount, drop mainly under the premise of ensureing requirement for anticorrosion, reducing air hose weight as possible
Low cost, while meeting the flexible requirement of structural elasticity connection.
In order to achieve the above object, the present invention provides a kind of loop type connection structure of PVC air hoses, including cross section is circle
One end of first PVC air hoses of shape, the PVC air hoses is equipped with the interconnecting piece that diameter is more than air hose pipe diameter, the interconnecting piece
The 2nd PVC air hoses of internal activity grafting, by being embedded in the interconnecting piece between the 2nd PVC air hoses and the interconnecting piece
Sealing rubber ring sealing on inner wall.
The length of the interconnecting piece is 210mm, and the length that the 2nd PVC air hoses are inserted into inside the interconnecting piece is
150mm。
Scope of activities of the 2nd PVC air hoses inside the interconnecting piece is 20mm~30mm.
The loop type connection structure of above-mentioned PVC air hoses, under preferred embodiment, the tube body of the first PVC air hoses and described
The outer diameter of the tube body of two PVC air hoses is 350mm, and the internal diameter of the interconnecting piece is 350mm.
The loop type connection structure of above-mentioned PVC air hoses, under preferred embodiment, the tube body of the first PVC air hoses and described
Multiple trepannings are arranged on the tube body of two PVC air hoses.
The loop type connection structure of above-mentioned PVC air hoses, under preferred embodiment, multiple trepannings are along the length side of the tube body
To spacing be 400mm.
The loop type connection structure of above-mentioned PVC air hoses, under preferred embodiment, adjacent two trepannings are arranged in a crossed manner.
The loop type connection structure of PVC air hoses of the present invention is applied to cattle carrier fence area ventilating system, is enclosed in satisfaction
Under the premise of material antiseptic requires in column area, cost substantially reduces, while the more conventional air hose of weight reduces by more than 50.In addition, living
Shell type connection type greatly reduces construction workload, and using method is not fully inserted, has self-adjusting function, every section of kink
Pipe stroke is 20mm~30mm, it is not necessary that elastic connection air hose is arranged.Desired effect is reached by actual use, price is just
Preferably, light-weight, construction operation convenience, installation are facilitated, are conveniently adjusted, meeting code requirement.Shipowner is obtained, ship is examined, AMSA works as
The generally approval of office.
Description of the drawings
Fig. 1 is the side sectional view of the loop type connection structure of PVC air hoses of the present invention；
Fig. 2 is the trepanning arrangement schematic diagram on the first PVC air hose tube bodies of the present invention.
In figure, the 1, the first PVC air hoses, 2, interconnecting piece, the 3, the 2nd PVC air hoses, 4, sealing rubber ring.
Specific implementation mode
As shown in Figure 1, a kind of loop type connection structure of PVC air hoses of the present invention, including cross section are circular first PVC
Air hose 1, one end of the first PVC air hoses 1 are equipped with the interconnecting piece 2 that diameter is more than air hose pipe diameter, the interconnecting piece 2 it is interior
The 2nd PVC air hoses 3 of portion's activity grafting, by being embedded in the interconnecting piece between the 2nd PVC air hoses 3 and the interconnecting piece 2
Sealing rubber ring 4 on 2 inner walls seals.
The length of the interconnecting piece 2 is 210mm, and the 2nd PVC air hoses 3 are inserted into the length inside the interconnecting piece 2
For 150mm.
Scope of activities of the 2nd PVC air hoses 3 inside the interconnecting piece 2 is 20mm~30mm.
The outer diameter of the tube body of the first PVC air hoses 1 and the tube body of the 2nd PVC air hoses 3 is 350mm, the connection
The internal diameter in portion 2 is 350mm.
As shown in Fig. 2, arranging multiple open on the tube body of the first PVC air hoses 1 and the tube body of the 2nd PVC air hoses 3
Hole.The spacing of length direction of multiple trepannings along the tube body is 400mm, and two adjacent trepanning intersections are set
It sets.
The present invention, as air feed air hose, has following characteristic using loop type linking pvc pipe：
PVC material itself has flame-retarding characteristic, meets ship and is applicable in requirement.
Compared with the stainless steel for having same antiseptic property, pvc pipe price is cheaper, while PVC pipe surface light
It is sliding, it is easier to rinse cleaning in actual use, and be suitable for seawater flushing.
PVC material density is about 1.4 × 103kg/m3, the 1/5 of insufficient stainless steel density, the pipeline of identical caliber, wall thickness
Under the premise of doubling, weight is still than 50% or more metal bellows loss of weight.
It needs largely to drill on fence area air hose, single ship drilling amount about 15000, compared with drilling on metal bellows, PVC
Drilling is simply many on pipe, and the drilling device cost used is also greatly lowered.
Using the loop type connection structure of PVC air hoses, and kink connector is integrally machined with pipe and (is i.e. processed into pipe one end
The interconnecting piece of kink joint form), cancel individual casing requirements, reduces the cost input of casing joint, and practice of construction
In reduce the connection work of half, greatly reduce construction volume.
Kink joint PVC air hoses are inserted into use and be not fully inserted, and are sealed using sealing rubber ring, actual use
In, PVC air hoses intubating length can be flexible coupling, simultaneously with flexible voluntarily the adjusting of structural elasticity connection it is not necessary that air hose is specially arranged
Air hose will not be destroyed.In addition, because being kink connection, such as there is error in practice of construction, adjustment is got up also more convenient.
The present invention replaces common metal air hose and PVC pipes peculiar to vessel only in fence area using with loop type pvc pipe.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope of present disclosure, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
