Description
Technical field
It is especially a kind of for the dedicated of cylinder cover for diesel engine priming valve dismounting the utility model relates to a kind of dismantling device
Tool belongs to hardware tool technical field.
Background technique
Four stroke medium seed diesel engine of large-diameter is rushed by the way of cylinder starts using compressed air and starts diesel engine, each
A priming valve is configured in cylinder head, compressed air successively opens each cylinder priming valve, compressed air according to diesel engine firing order
Cylinder is entered by main air line, pushes piston motion, so that diesel engine is under fire and runs.Due to compressed air and operation diesel engine combustion
Burning indoor fuel gas has very high pressure, therefore, priming valve and valve opening very high to each contact surface seal request of priming valve and valve opening
Machining accuracy it is also very high, this requires needing to reinforce the surfacecti proteon of components during the installation and removal of priming valve,
Once sealing surface damages, it will lead to gas leakage, influence diesel engine starting.Priming valve itself has constant weight, and cylinder head simultaneously
Upper valve hole depth is deeper, and there are certain difficulty for the installation and removal of priming valve, if without special tool auxiliary starting valve
Installation and removal, it is difficult to ensure priming valve it is good fit, be greatly reduced the disassembly efficiency of priming valve.
Utility model content
Be simple and convenient to operate the purpose of the utility model is to provide a kind of structure and can effective protection priming valve diesel oil
Machine cylinder head priming valve dismantling device.
The utility model is achieved by the following technical programs:
A kind of cylinder cover for diesel engine priming valve dismantling device, including guide rod, briquetting, hoisting nut and eyenut；Institute
It states guide rod lower end to be spirally connected with the hanging bolt on cylinder head priming valve, briquetting movable sleeving is on guide rod upper end, briquetting bottom
Portion is supported on the step of cylinder head valves hole, and the hoisting nut is located on the upside of briquetting, and screws fixation with guide rod upper end, described
Eyenut is fixed on the end of guide rod upper end.
The purpose of this utility model can also be further realized by following technical measures.
Cylinder cover for diesel engine priming valve dismantling device above-mentioned, wherein the guide rod is studs structure.
Cylinder cover for diesel engine priming valve dismantling device above-mentioned, wherein the guide rod upper end end is equipped with stud head,
Eyenut screws on the stud head, and guide rod lower end surface is equipped with screw hole, and the screw hole is screwed in cylinder head priming valve
Hanging bolt on.
Cylinder cover for diesel engine priming valve dismantling device above-mentioned, wherein the briquetting is connected to fall T by seat ring and casing
Shape tube-in-tube structure.
Cylinder cover for diesel engine priming valve dismantling device above-mentioned, wherein the seat ring is step structure, seat ring is supported on
On the step of cylinder head valves hole.
The utility model structure is simple, at low cost, flexible and convenient operation, can easily fill priming valve from cylinder head valve opening
Enter and splits out, it, can effective protection starting valve sealing surface and sealing ring in disassembly process due to the guiding role of briquetting and guide rod
It is not damaged, to guarantee that diesel engine smoothly starts, greatly improve the disassembly efficiency of priming valve.The wherein seat ring of briquetting bottom
It is designed to step structure, briquetting support can be made more reliable and more stable, to play better guiding role, eyenut can facilitate
Priming valve is hung out into cylinder head valve opening.
The advantages of the utility model and feature will carry out diagram reconciliation by the non-limitative illustration of preferred embodiment below
It releases, these embodiments, is only provided as an example referring to attached drawing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model guide rod.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the utility model includes guide rod 1, briquetting 2, hoisting nut 3 and eyenut 4.Guiding
Bar 1 is studs structure, and 1 upper end end of guide rod is equipped with stud head 11, and eyenut 4 screws on stud head 11, is oriented to
1 lower end surface of bar is equipped with screw hole 12, and screw hole 12 screws on the hanging bolt 51 of cylinder head priming valve 5.Briquetting 2 is by 21 He of seat ring
The weldering of casing 22 is linked as inverted T-shaped tube-in-tube structure, and briquetting 2 is sleeved on 1 upper end of guide rod, and guide rod 1 can move down on 2 inner hole of briquetting
Dynamic, the seat ring 21 on briquetting 2 is step structure, and seat ring 21 is supported on 52 step of cylinder head valve opening.Hoisting nut 3 is located at briquetting
2 upsides, and fixation is screwed with 1 upper end of guide rod.
The utility model operating process is as follows:
The gland of cylinder head priming valve 5 is removed, while the screw hole 12 of 1 lower end of guide rod is screwed into cylinder head priming valve 5
On hanging bolt 51, then briquetting 2 is sleeved on guide rod 1, is supported on 2 bottom of briquetting on 52 step of cylinder head valve opening,
To position briquetting 2, hoisting nut 3 is screwed on guide rod 1 and turns hoisting nut 3, guide rod 1 drives cylinder at this time
Lid priming valve 5 is lifted up along 2 inner hole of briquetting and moves, and continues to turn hoisting nut 3 until cylinder head priming valve 5 completely disengages gas
Cylinder head priming valve 5 is hung cylinder head finally by eyenut 4 by cylinder cap valve opening 52, after remove dismantling device.
In addition to the implementation, the utility model can also have other embodiments, all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, is all fallen in the protection scope of the requires of the utility model.
