Aiming at the defects of the prior art, the invention provides a method for eliminating the gap at the joint of two pipelines by using a hoop, so that food is low in residue, pollution of the uncontrollable pipelines is avoided, all welding and polishing processes are carried out in a workshop, and stainless steel pipes are connected on a ship only through the hoop joint.
In order to achieve the purpose, the invention provides the following technical scheme: a manufacturing and mounting process of a marine food-grade pipeline comprises the following steps:
1) preparing parts, namely prefabricating a stainless steel pipe in a clean workshop, welding all parts needing to be welded with the stainless steel pipe in the workshop, polishing a welding line after welding, cleaning the inside of the stainless steel pipe and keeping a clean state;
2) and (3) mounting on a ship, transferring all the stainless steel pipes to the ship, sequentially connecting the stainless steel pipes, and connecting two adjacent stainless steel pipes through a hoop joint.
Further the clamp connects and includes two sections connecting core, gasket and clamp, two sections connecting core are fixed connection respectively and are being close to the tip at two nonrust steel pipes, the clamp is used for two sections fixed connecting core, the gasket is located between two sections connecting core, the gasket includes solid fixed ring and compensating plate, the tip of connecting core includes plane portion and first conical surface portion, first conical surface portion is close to the axis of connecting the core, the compensating plate of gasket be provided with first conical surface portion complex second conical surface portion, gu fixed ring arranges in between the plane portion of two connecting cores, second conical surface portion is located first conical surface portion department, connects the core and welds at nonrust steel pipe tip in the workshop, when boats and ships, arranges the gasket in between two connecting core, and then the clamp is overlapped on connecting the core to lock the clamp gradually through the moment spanner.
Compared with the prior art, the invention has the beneficial effects that: the pipeline meeting the food-grade requirement is used on the ship, all welding and polishing processes are completely carried out in a clean workshop, and the pipeline is connected only through the clamp connector on the ship with the severe environment, so that the speed block is connected, the pollution to the inside of the stainless steel pipe during the installation of the ship can be avoided, and the defects that the conventional pipeline is easy to pollute, large in residue, difficult to clean and the like are effectively avoided; in addition, the marine food-grade pipeline has high reliability, so that the subsequent maintenance is greatly reduced, and the effects of cleanness, high efficiency and cost reduction are achieved.

Detailed Description
The manufacturing and installation process of the marine food-grade pipeline of the invention is further described with reference to fig. 1 to 3.
A manufacturing and mounting process of a marine food-grade pipeline comprises the following steps:
1) preparing parts, prefabricating a stainless steel pipe 1 in a clean workshop, welding all parts needing to be welded with the stainless steel pipe 1 in the workshop, polishing welding seams after welding, cleaning the inside of the stainless steel pipe 1 and keeping a clean state, wherein the parts usually comprise parts such as an eccentric reducing part 2, a diaphragm valve 4, a tee joint 5, a ball valve 6, an elbow 7 and the like;
2) and (3) mounting on a ship, transferring all the stainless steel pipes 1 to the ship, sequentially connecting the stainless steel pipes 1, and connecting the two adjacent stainless steel pipes 1 through a hoop joint 3.
The clamp joint 3 comprises two sections of connecting cores 32, a gasket 33 and a clamp 31, wherein the two sections of connecting cores 32 are respectively and fixedly connected with the end parts of the two stainless steel pipes 1 close to each other, the clamp 31 is used for fixing two connecting cores 32, the gasket 33 is positioned between the two connecting cores 32, the gasket 33 includes a fixing ring 332 and a compensation plate 331, the end of the connection core 32 includes a flat portion and a first tapered portion, the first tapered surface portion is close to the axis of the connecting core 32, the compensation plate 331 of the spacer 33 is provided with a second tapered surface portion that mates with the first tapered surface portion, the fixing ring 332 is disposed between the two flat portions of the connecting core 32, the second tapered portion is located at the first tapered portion, the connecting core 32 is welded to the end of the stainless steel pipe 1 in the workshop, when on board the vessel, the washer 33 is placed between the two connection cores 32, and the rear clip 31 is fitted over the connection cores 32 and the clip 31 is gradually locked by means of a torque wrench.
The concrete principle does, at first accomplishes welding and polishing process in clean workshop, later can carry out effectual cleanness to it, when installing on boats and ships, through the installation that clamp joint 3 can be quick, save time avoids nonrust steel pipe 1 to expose for a long time simultaneously and causes extra pollution outward.
Wherein both surfaces of the fixing ring 332 in contact with the end surfaces of the connecting core 32 are planes perpendicular to the axis, in assembly, the shim 33 is first placed between the two connecting cores 32, and the compensation plate 331 is clamped at the first conical portion, while the fixing ring 332 is located between the two end faces of the connecting core 32, then the clamp 31 is sleeved outside the end part of the connecting core 32, the end part of the connecting core 32 extends into the groove, as the clamp 31 is continuously locked, the two connecting cores 32 gradually approach and press the gasket 33, the second conical surface part and the first conical surface part of the compensation plate 331 move due to the pressing, i.e., the spacer 33 and the connecting core 32 are centered automatically, and the fixing ring 332 can limit the locking condition of the two connecting cores 32, i.e. the minimum distance between the two connecting cores 32, when the two connecting cores 32 reach the minimum distance, the compensation plate 331 will be flush with the inner wall of the connecting core 32 at this time, and completely block the gap, so as to meet the food-grade requirement.
