Abstract
This utility model provides a kind of high pressure gas pipeline and connects tightening structure, its problem that can solve air inlet tube gas leakage easy to crack when existing high pressure gas pipeline tightening structure is applied in high-power diesel engine, there is potential safety hazard.It includes the adapter of both sides air inlet pipe, rubber and arm-tie, the two ends of rubber adapter are socketed with the connection end of both sides air inlet pipe respectively, rubber is taken over the socket section periphery with both sides air inlet pipe and is radially held tightly by anchor ear respectively, it is characterized in that: on the tube wall of both sides air inlet pipe, have through hole, being mounted on arm-tie positioning component in through hole, the both sides of arm-tie are respectively arranged on the arm-tie positioning component of both sides air inlet pipe.
Description
Technical field
This utility model relates to diesel engine pipeline jointing construction field, and after especially relating to diesel engine supercharging, air inlet pipeline is even
Access node structure, is specially a kind of high pressure gas pipeline and connects tightening structure.
Background technology
After diesel engine intake intensified device supercharging, pressure is higher, and usual relative pressure is at about 200kPa, for improving air inlet
The dimension compensation ability of pipeline, both sides air inlet pipe 1a, 1b generally use rubber adapter 8 to connect, and rubber adapter 8 is taken over both sides again
Held tightly by anchor ear 7a, 7b respectively between 1a, 1b, see Fig. 1；Cause for preventing gases at high pressure from making connecting line generation move radially
Inefficacy is held in rubber adapter tightly, it will usually increase welding lug 2a, 2b, two welding lugs on both sides air inlet pipe 1a, 1b respectively
Fixed by arm-tie 6 and bolt 3 between 2a, 2b.But along with the more powerful lifting of diesel engine and the raising of reinforcing degree, coupling
Charger boost after pressure improve further, relative pressure reaches 300kPa, higher have reach more than 350kPa, and diesel engine
After power improves, diesel vibration also strengthens, and high temperature makes the air inlet around welding lug in the welding process of welding lug
Tube material becomes fragile, under higher admission pressure and larger vibration, easy to crack at this, and the most whole welding lug is from air inlet pipe
Come off, thus cause principal fault.
Summary of the invention
For the problems referred to above, this utility model provides a kind of high pressure gas pipeline and connects tightening structure, and it can solve existing
Air inlet tube gas leakage easy to crack when high pressure gas pipeline tightening structure is applied in high-power diesel engine, exist potential safety hazard ask
Topic.
Its technical scheme is, it include both sides air inlet pipe, rubber adapter and arm-tie, described rubber adapter two ends respectively with
The connection end socket of both sides air inlet pipe, the socket section periphery of the adapter of described rubber and both sides air inlet pipe is radially embraced by anchor ear respectively
Tightly, it is characterised in that: on the tube wall of described both sides air inlet pipe, have through hole, in described through hole, be mounted on arm-tie location
Assembly, the both sides of described arm-tie are respectively arranged on the arm-tie positioning component of described both sides air inlet pipe.
Further, described arm-tie positioning component includes bolt and flange nut, and described bolt is from air inlet pipe
Interior outside air inlet pipe, run through described through hole and threaded with described flange nut so that described bolt is whole with flange nut
Body is the tightest on described air inlet tube wall, and described arm-tie is placed on the top external part of described bolt and leads to be locked by locking nut
Tight in the end face of described flange nut.
Further, described air inlet pipe is positioned on the inner side tube wall of described through hole and is provided with copper backing, described copper backing
Area coverage is more than described via area, and described bolt sequentially passes through after described copper backing, through hole from inside to outside with described
Flange nut is threaded and tight.
The beneficial effects of the utility model are: it is by the arm-tie location being respectively provided at both sides in air inlet pipe tube wall through hole
Arm-tie installed by assembly, and the installation of arm-tie positioning component will not destroy the strength of materials of air inlet pipe, thus both can guarantee that arm-tie
Straining both sides air inlet pipe, to be prevented effectively from again air inlet high pressure and diesel vibration in the course of the work fixed to air inlet pipe and arm-tie
The infringement of hyte part, it is to avoid the cracking fault of air inlet pipe, it is ensured that diesel engine properly functioning；And its arm-tie positioning component uses and determines
Position bolt and the fit structure of flange nut, its simple in construction, arm-tie location is reliable；Additionally it is ensured logical by copper backing
The sealing in hole, it is ensured that the sealing of air inlet pipe is without gas leakage.
