Description
Technical field
The utility model relates to Diesel Engine Technique Field, particularly relates to a kind of double fuel mixed power cylinder starting valve peculiar to vessel.
Background technique
Cylinder starting valve is the important valve member of diesel engine starting system, requires that it can open rapidly in starting process.It is controlled by air distributor, opens and is opened by control air, close and rely on spring force.When inner pressure of air cylinder should be closed higher than during starting air pressure.Along with the repeatedly unlatching of cylinder starting valve closes, gas of combustion in cylinder enters valve body, carbon is formed gradually around valve rod and starting valve casing wall, when diesel engine starting, carbon causes in the middle of the stuck guide pin bushing in cylinder starting valve of valve rod, cannot normally work, so that cylinder starter gate valve needs are made regular check on, maintenance.
Model utility content
The utility model is stuck in the middle of guide pin bushing for solving valve rod, cannot normally work, so that cylinder starter gate valve needs are made regular check on, the problem of maintenance, provides a kind of double fuel mixed power cylinder starting valve peculiar to vessel.
For solving the problems of the technologies described above, the technical solution of the utility model is: double fuel mixed power cylinder starting valve peculiar to vessel, comprise valve casing, valve rod, valve gap, piston and spring, the inside of valve casing is cascade cavity structure, the valve port place, bottom of valve casing is provided with the conical surface, the bottom of valve casing offers several compressed air inlet ports, the inner chamber of valve casing and guide pin bushing interference fit, in valve casing, piston is installed, spring, the piston body of piston and the inner chamber of valve casing are slidably connected, on the piston rod that spring housing is contained in piston and spring is positioned at the top of guide pin bushing, the top of valve rod is successively through guide pin bushing, piston is also fixedly connected with piston, seal between the bottom conical surface of valve rod and the conical surface at valve casing valve port place, the outer wall of valve casing offers seal groove, in seal groove, seal ring is installed, valve gap is fixedly connected with the top of valve casing, seal between valve gap and valve casing, valve gap is offered control air inlet.
Further, compressed air inlet port is strip.
Further, the top of valve rod is fixedly connected with by self-locking nut with piston.
Further, valve gap is fixedly connected with by hex head bolt with the top of valve casing.
Further, sealed by sealing gasket between valve gap and valve casing.
The utility model structure is simple, and volume is little, and be convenient to dismounting, install and maintenance, valve rod is not easily stuck in the middle of guide pin bushing, ensure that normal work, greatly reduces the making regular check on of cylinder starter gate valve, maintenance.
Accompanying drawing explanation
Fig. 1 is the utility model plan view;
Fig. 2 is the A-A direction view of Fig. 1.
Wherein: 1. valve casing, 2. valve rod, 3. valve gap, 4. piston, 5. guide pin bushing, 6. spring, 7. seal ring, 8. sealing gasket, 9. hex head bolt, 10. self-locking nut.
Embodiment
As Fig. 1, shown in Fig. 2, double fuel mixed power cylinder starting valve peculiar to vessel, comprise valve casing 1, valve rod 2, valve gap 3, piston 4 and spring 6, the inside of valve casing 1 is cascade cavity structure, the valve port place, bottom of valve casing 1 is provided with the conical surface, the bottom of valve casing 1 offers the compressed air inlet port of several strips, the inner chamber of valve casing 1 and guide pin bushing 5 interference fit, piston 4 is installed in valve casing 1, spring 6, the piston body of piston 4 and the inner chamber of valve casing 1 are slidably connected, on the piston rod that spring 6 is sleeved on piston 4 and spring 6 is positioned at the top of guide pin bushing 5, the top of valve rod 2 is successively through guide pin bushing 5, piston 4 is also fixedly connected with piston 4 by self-locking nut 10, seal between the bottom conical surface of valve rod 2 and the conical surface at valve casing 1 valve port place, the outer wall of valve casing 1 offers seal groove, seal ring 7 is installed in seal groove, valve gap 3 is fixedly connected with by hex head bolt 9 with the top of valve casing 1, sealed by sealing gasket 8 between valve gap 3 and valve casing 1, valve gap 3 is offered control air inlet.Controlling air enters in valve by the control air inlet on valve gap 3, promoting piston 4 is with ovable valve stem 2 to move down, the conical surface closed mutually between valve rod 2 with valve casing 1 is separated, cylinder starting valve is opening state, and pressurized air is entered in valve by the compressed air inlet port on valve casing 1 and enters cylinder by opening face; When control air is closed, when the pressure in cylinder is higher than control air pressure, spring 6 promotes piston 4 and moves up, and piston 4 is resetted, and is with ovable valve stem 2 to move up simultaneously, and make it to close with the conical surface on valve casing 1, cylinder starting valve is closed condition.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
