Abstract
A kind of steam turbine top petrol tank is the utility model is related to, is specifically a kind of two valve block structures.Purpose is to provide a kind of steam turbine top petrol tank of the valve group of band two, and the fuel tank should be able to meet steam turbine operation requirement, and have the characteristics of simple in construction and easy to maintenance.Technical scheme is：Steam turbine top petrol tank with two valve groups, including top petrol tank body；It is characterized in that：The top petrol tank body imports and exports the first pipeline connected, and stop valve is set on the first pipeline；Second pipe is connected in parallel with the first pipeline, and check-valves is set on second pipe；Throttle orifice is set on the valve plate of the check-valves.
Description
Technical field
A kind of steam turbine top petrol tank is the utility model is related to, is specifically a kind of two valve block structures.
Background technology
Top petrol tank be in the state of accident provide halt turbines process needed for lubricating oil equipment, its operation principle
It is：Top petrol tank is directly connected to lubricating pipe by three valve groups, and after petrol station puts into operation, lubricating pipe passes through three valve groups
Stop valve top petrol tank is carried out oil-filled, until closing stop valve after being full of, top petrol tank is furnished with oil spilling mouth, the fluid diffused out
Main fuel tank is flowed back to from oil spilling mouth；During normal operation, lubricating pipe carries out rill by the choke valve of three valve groups to top petrol tank
Measure oil-filled, guarantee oil temperature；During accident condition the fluid of top petrol tank under gravity, by the check-valves of three valve groups in turn
It is oil-filled to lubricating pipe, to ensure that Turbine Safety is shut down.But because three valve block structures are complex, I＆M into
This is higher, and popularization and application difficulty is larger.
Utility model content
The purpose of this utility model is overcome the shortcomings of in above-mentioned background technology, there is provided a kind of steam turbine of valve group of band two is used
Top petrol tank, the fuel tank should be able to meet steam turbine operation requirement, and have the characteristics of simple in construction and easy to maintenance.
The technical solution of the utility model is：
Steam turbine top petrol tank with two valve groups, including top petrol tank body；It is characterized in that：The top petrol tank sheet
Body imports and exports the first pipeline connected, and stop valve is set on the first pipeline；Second pipe is connected in parallel with the first pipeline, and second
Check-valves is set on pipeline；Throttle orifice is set on the valve plate of the check-valves.
The aperture of the throttle orifice is 4-10mm.
The top petrol tank body is provided with steam drain, manhole cover and oil spilling mouth.
The beneficial effects of the utility model are：
A variety of works such as the utility model can put into operation in steam turbine and oil supply system, normal operation and emergency shutdown
Flow of lubrication is accurately adjusted during condition, ensures equipment safety, while two valve block structures are relatively simple, greatly facilitate later maintenance
Work.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is the main structure diagram of check-valves.
Fig. 3 is the left view structural representation of check-valves.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
As shown in figure 1, the steam turbine top petrol tank of the valve group of band two, including top petrol tank body 1；The top petrol tank sheet
The top of body is provided with steam drain 11 and manhole cover 12, and the side wall of top petrol tank body is provided with oil spilling mouth 13 and inlet and outlet 10, oil spilling
Mouth is located at lower sidewall positioned at side wall upper part and inlet and outlet.
The inlet and outlet connect lubricating pipe (being omitted in figure) by two valve groups 2；Two valve group includes being connected in parallel
The first pipeline 31 and second pipe 32, stop valve 21 is set on the first pipeline, check-valves 22 is set on second pipe.It is described to stop
Return and throttle orifice 4 is set on the valve plate of valve.The aperture of the throttle orifice is 4-10mm (preferably 6mm).
Operation principle of the present utility model is：
1st, when steam turbine and oil supply system put into operation, stop valve is opened, lubricating pipe is quickly oil-filled to top petrol tank
(lubricating oil is flowed to as shown in arrow F1 in figure), the manual-lock stop valve after top petrol tank is full of oil；
2nd, during normal operation, the lubricating oil in lubricating pipe is passed through only with less flow for steam turbine and oil supply system
The throttle orifice returned on valve valve plate enters top petrol tank (lubricating oil is flowed to as shown in arrow F1 in figure), so that the oil in top petrol tank
Liquid keeps the state of flowing, and oil temperature and the oil temperature of whole lubricating pipe are basically identical；
3rd, when steam turbine runs into emergency and needs to shut down, the fluid in top petrol tank is pushed open only automatically under gravity
Return valve and enter lubricating pipe (lubricating oil flows to as indicated by the arrow f 2), the positions such as steam turbine bearing are lubricated, really
Turbine Safety is protected to shut down.
