Description
Technical field
The utility model relates to a kind of novel steam dynamo bearing flow control valve, belongs to the technical field that generator is manufactured.
Background technique
Bearing is one of critical component affecting Turbo-generator Set operation stability; bearing of turbo generator set belongs to a kind of hydrodynamic sliding bearing; hydrldynamic pressure lubrication is the relative movement relying between lubricated a pair of solid friction face; make to produce pressure in the lubricating fluid film between between solid; to bear external load, exempt being in contact with one another between solid, thereby play the effect of capable of reducing friction resistance and protection solid surface.Therefore, providing of lubricant oil is the assurance of bearing safe operation, for the better oil inlet quantity that regulates sliding bearing, guarantee the safe and reliable of bearing operation, just must design a kind of flow control valve that can meet steam turbine generator safe operation needs carrys out regulator generator bearing oil inlet quantity for we.
The oil inlet quantity of traditional steam turbine generator bearing is to adopt the restricting orifice in several apertures to try to adjust, and finally selects the restricting orifice in a suitable aperture.In installing at the scene, adopt in this way: the one, very inconvenient, need to repeatedly shut down trial assembly, cause economical and temporal waste; The 2nd, cause many lubricating oil splash and waste, affect environment.
Summary of the invention
The problem that the purpose of this utility model exists in order to overcome above-mentioned prior art, and a kind of novel steam dynamo bearing flow control valve is provided.The utlity model has simple in structure, quick and easy for installation, safe and reliable to operationly, in unit operation, can carry out the flow control valve of Flow-rate adjustment.In design process, taken into full account manufacture cost, structure is small and exquisite and the factor such as serial unit versatility, has successfully designed all flow control valves applicatory of a kind of 6MW-60MW Turbo-generator Set.
The technical solution of the utility model:
Novel steam dynamo bearing flow control valve, by valve body, valve gap, Stem Mut, valve rod and spool, formed, it is characterized in that: in valve body, be provided with oil inlet hole and oil outlet, valve rod passes valve gap and by Stem Mut and valve gap, fixedly realizes the rotation of valve rod, valve gap is fixed on valve body, and valve rod stretches into one end of valve body spool is installed.
Oil inlet hole on described valve body becomes the angle of 90 degree with oil outlet, design is on two adjacent planes of valve body, effectively reduce the volume of valve body, also more met the cloth form of tubes of flow control valve in as installed process, made on-the-spot stringing and adjust flux more convenient.
Described valve body is shaped as square body.
Described spool is shaped as taper.
The diameter of described taper valve core is less than oil inlet hole diameter, so that still can provide the oil inlet quantity of bearing safe operation when valve is closed completely.
Sealing between valve gap and valve body, valve rod and valve gap all adopts two O RunddichtringO sealings.Spool and valve rod are fabricated construction, whole easy to assembly, can change spool.Oil inlet and outlet adopts M42x2 fine thread, can directly be connected with JB/T966 styletable free flow coupling ZZJ-35.The utility model has adopted modular design concept, and the in-line supply in full sets that Yu You manufactory provides can directly be connected by screw thread with the pipe joint of standard piece, easy for installation, can be according to the flexible stringing of on-the-spot installation conditions.
Adopt flow control valve of the present utility model, not only overcome the installation shortcoming of restricting orifice, but also regulate easily the oil inlet quantity of bearing.It is to carry out within the scope of minimum oil inlet quantity and maximum oil inlet quantity that the oil inlet quantity of flow control valve regulates, and has guaranteed that bearing can oil-break tile kilning.
The utility model is simple in structure, on-the-spot installation and adjust flux are more convenient, even can in unit running process, according to data on flows being detected, carry out at any time Flow-rate adjustment, and the minimum stream value that this flow control valve being provided with can be adjusted to, avoided, because misoperation is closed valve completely, occurring interruption of service.
Beneficial effect: realize the adjusting of steam turbine generator bearing oil inlet quantity by this Novel flow control valve, greatly reduce the workload of power plant in installation and Flow-rate adjustment process, improved the Economy of unit operation, also make the operation of unit more safe and reliable simultaneously.Novel flow control valve can directly be connected by screw thread with the pipe joint of standard piece, more convenient flexibly at erecting bed stringing.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the connection diagram of flow control valve of the present utility model and inflow pipeline.
Embodiment
The utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model is comprised of valve body 1, valve gap 2, Stem Mut 3, valve rod 4 and spool 10, is provided with oil inlet hole and oil outlet in valve body 1; Valve rod 4 is through valve gap 2 and by Stem Mut 3(screw 6, be the Cock screw of Stem Mut 3) and valve gap 2 fixedly realize the rotation of valve rod 4; Valve gap 2 is fixed on valve body 1 by another screw 7, and valve rod 4 stretches into one end of valve body 1 spool 10 is installed; Valve gap 2 seals with the two O RunddichtringOs 8 of employing of valve body 1, adopts 9 sealings of another pair of O RunddichtringO between valve rod 4 and valve gap 2; Spool is fixed on valve rod 4 by nut 11; Thin nut 5 is the locking nut after valve rod 4 regulates.
Described valve body is shaped as square body, and the oil inlet hole on valve body 1 becomes the angle of 90 degree with oil outlet, design is on two adjacent planes of valve body 1, effectively reduced the volume of valve body, also more meet the cloth form of tubes of flow control valve in as installed process, make on-the-spot stringing and adjust flux more convenient.Described spool 10 is shaped as taper, and the diameter of taper valve core is less than oil inlet hole diameter, so that still can provide the oil inlet quantity of bearing safe operation when valve is closed completely.
The utility model design process is:
