Abstract
The utility model discloses a feed water pump recycling multi-disc combination closure ring which comprises single-disc closure rings (1) and diversion grooves (2). A plurality of the single-disc closure rings (1) are combined to form a whole in a superposition mode. A valve core hole (3) is formed in the center of each single-disc closure ring (1). The diversion grooves (2) are formed in both sides of each single-disc closure ring (1). The feed water pump recycling multi-disc combination closure ring has the advantages of reducing differential pressure, reducing vibration, resisting cavitation and erosion, being capable of preventing equipment from being damaged due to vibration in operation, and ensuring that service life of valves is prolonged.
Description
Technical field
The utility model relates to a kind of feed water pump recycle valve door assembly, especially relates to a kind of feed water pump recirculation multi-disc combination shutoff ring.
Background technique
At present mostly valve manufacturing firm all adopts traditional telescopic shutoff ring to High Pressure Difference feed water pump small flow, and telescopic shutoff ring does not possess the function of falling large pressure reduction, in the long-play of valve, due to washing away of large pressure reduction, usually cause spool to be washed out, leakage current occuring when making the valve complete shut-down, and shortened the working life of spool, has a strong impact on the economical operation of unit.
The model utility content
The purpose of this utility model is to solve the defective of telescopic shutoff ring, provides a kind of and can prevent the equipment feed water pump recirculation multi-disc combination shutoff ring because of the vibration cause damage of equipment in service.
The technical solution of the utility model is: a kind of feed water pump recirculation multi-disc combination shutoff ring comprises monolithic shutoff ring (1) and guiding gutter (2).Be superimposed to form integral body by a plurality of monolithic shutoff rings (1).The center of each monolithic shutoff ring (1) is provided with spool bore (3).The tow sides of each monolithic shutoff ring (1) are provided with guiding gutter (2).
Beneficial effect:
Owing to taking such scheme, be superimposed to form integral body by a plurality of monolithic shutoff rings (1), easy accessibility when traffic requirement changes, can be repaired uninterrupted and more preferably flow curve voluntarily.The center of each monolithic shutoff ring (1) is provided with spool bore (3).The tow sides of each monolithic shutoff ring (1) are provided with guiding gutter (2).In valve working, guiding gutter (2) with fluid flow guiding to the spool bore (3) of every monolithic shutoff ring (1) or the edge of every monolithic shutoff ring (1), reduced the pressure reduction of fluid, reduced the vibration of valve, play the effect of anti-cavitation erosion, resistance to erosion, the equipment that can prevent is in service because of the vibration cause damage of equipment, is the assurance of valve long service life.
Description of drawings
Fig. 1 is plan view of the present utility model;
In Fig. 1,1-monolithic shutoff valve, 2-guiding gutter, 3-spool bore;
Fig. 2 is left view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, 2, a kind of feed water pump recirculation multi-disc combination shutoff valve comprises monolithic shutoff ring 1 and guiding gutter 2.Be superimposed to form integral body by a plurality of monolithic shutoff rings 1, easy accessibility when traffic requirement changes, can be repaired uninterrupted and more preferably flow curve voluntarily.The center of each monolithic shutoff ring 1 is provided with spool bore 3.The tow sides of each monolithic shutoff ring 1 are provided with guiding gutter 2.In valve working, guiding gutter 2 to the spool bore 3 of every monolithic shutoff ring 1 or the edge of every monolithic shutoff ring 1, has reduced the pressure reduction of fluid with fluid flow guiding, has reduced the vibration of valve, plays the effect of shouldering cavitation erosion, resistance to erosion, is the assurance of valve long service life.
