Description
Technical field
This utility model relates to the technological equipment of marine diesel assembling, is specifically related to a kind of positioner installed for marine diesel exhaust header, belongs to diesel engine manufacturing technology field.
Background technology
Exhaust header is one of particularly important parts of marine diesel, refers to Fig. 1, and the suction flange 11 of exhaust header 01 is linked together by expansion pipe 02 and air bleeding valve 03.The waste gas that marine diesel oil machine host produces in running is discharged by air bleeding valve 03, and enters exhaust header 01 by expansion pipe 02.The EGT discharged when diesel engine runs reaches about 300 DEG C, under high temperature so, exhaust header 01 can raise along with temperature and expand, its profile also can deform, so that the position connecting the suction flange 11 of expansion pipe 02 is transversely subjected to displacement to two ends (in Fig. 1 by paper outwardly or inwardly).Expansion pipe 02 is a flexible steel in flat section tubing, intensity is not high, if initially installing the center of suction flange 11 during expansion pipe 02 and the center just centering of air bleeding valve 03 interface, the suction flange 11 position skew that then exhaust header 01 expansion causes can pull one end of expansion pipe 02 to move together, thus being easy to make the corrugated tube of expansion pipe 02 to deform, if suction flange 11 position offset is excessive, expansion pipe 02 even can be caused damaged and cause that waste gas leaks outside.
In order to solve the problems referred to above, take a measure, namely when installing exhaust header 01, the center of suction flange 11 and air bleeding valve 03 interface are staggered a position centrally along the opposite direction that exhaust header 01 expands, that is, by the center of a suction flange 11 reversely reserved side-play amount, then fixing exhaust header 01 is installed again.So when diesel engine runs and discharges waste gas, exhaust header 01 heats up and expands, and the mobile Shi Qi center of suction flange 11 is just directed at air bleeding valve 03 interface center, thus avoiding corrugated tube excessive deformation and causing that expansion pipe 02 is damaged.
But said method has a difficulty: owing to exhaust header 01 and the air bleeding valve 03 of marine diesel are all huge monsters, and between have certain distance, therefore exhaust header 01 is accurately put, the center of suction flange 11 and the initial position at air bleeding valve 03 interface center is made to meet predetermined amount of bias, this is a highly difficult thing, especially there is multiple suction flange 11 to connect with air bleeding valve 03 on exhaust header 01 and when reserved amount of bias is different, be difficult to the correct location and installation of exhaust header 01 especially.
Utility model content
The purpose of this utility model is in that, overcome the deficiencies in the prior art, a kind of positioner installed for marine diesel exhaust header is provided, exhaust header can be positioned easily when cold conditions, so as to the position at the position at suction flange center and expansion pipe interface center reaches the requirement of predetermined bias amount, thus when after ensureing exhaust header installation, marine diesel runs, expansion pipe will not cause breakage because of the thermal deformation of exhaust header.
The technical scheme in the invention for solving the technical problem is as follows:
A kind of positioner installed for marine diesel exhaust header, it is connected between suction flange and the outlet of air bleeding valve of described exhaust header, it is characterized in that: described positioner includes top flange, flange in the bottom and the four pieces of gussets being fixedly connected on vertically between this top flange and flange in the bottom, the upper end of these four pieces of gussets and described top flange are welded and fixed, lower end and described flange in the bottom are welded and fixed, described top flange offers position multiple connecting holes corresponding with installing hole on the suction flange of described exhaust header, described flange in the bottom offers position multiple bolts hole corresponding with described air bleeding valve upper screwed hole, the positional symmetry center of the plurality of connecting hole and the positional symmetry center of the plurality of bolt hole have a side-play amount in the horizontal.
Further, described side-play amount is equal to the reserved amount of bias between suction flange center and the export center of air bleeding valve of described exhaust header.
Further, the height of described positioner is equal to the distance between suction flange and the outlet of air bleeding valve of described exhaust header.
Further, described top flange and the middle part of flange in the bottom all offer lightening hole.
This utility model is before the installation of marine diesel exhaust header, it is possible to replaces expansion pipe to be connected between exhaust header and air bleeding valve, makes exhaust header be in offset position accurately, it is simple to correctly to install exhaust header.
Compared with prior art, this utility model achieves following technique effect:
1. use positioner described in the utility model, it is ensured that Relatively orientation accurately between exhaust header and air bleeding valve, it is to avoid cause loss unnecessary in running because of arranged in dislocation.
2. this utility model is easy to use, simple to operate, it is possible to makes operator complete exhaust header installment work within the very fast time, improves labor productivity.
