Abstract
A four-way rotary switching valve for air separation equipment has four symmetrical channels (1-4) on its valve body. The valve core is provided with two independent uniform and symmetrical arc-shaped channels 1-2. When the valve core rotates 90 degrees clockwise or anticlockwise, the four channels on the valve body are correspondingly communicated with the two arc-shaped channels in the valve core, so that the gas switching fluctuation is minimum, and the working efficiency of the air separation equipment is improved.
Description
The utility model relates to the COMM communication of a kind of existence in the air separation plant technological process, especially can solve the four-way rotation switching valve of drag flow gas and the gas crossfire when switching mutually that backflows.
At present, in the air separation plant technological process, what its COMM communication adopted is that the work of two three-way valve cooperation realizes drag flow gas and the mutual switching of the gas that backflows.When three-way valve is worked, being opened to the gas channel that backflows from positive circulation road closes, or be opened to this working procedure of drag flow pathway closure from reflux passage, existing positive circulation road and reflux passage gangs up, cause drag flow gas and backflow the gas crossfire, particularly drag flow gas is big more with the pressure reduction of the gas that backflows, and crossfire is serious more.The result of crossfire makes the air distillation tower internal pressure fluctuating range in the air separation plant technological process big, be unfavorable for that rectifying in the air distillation tower is unfavorable for the adjustment and the raising of product purity, has also run counter to the requirement that air separation plant is answered steady pressure.Simultaneously stuck, stagnation, seepage fault also take place in three-way valve easily, also cause whole air separation plant by forced-stopping machine when serious, have increased operator's workload, have also increased cost of production.
The purpose of this utility model provides a kind of four-way rotation switching valve, the crossfire problem that it can not only solve drag flow gas when switching mutually with the gas that backflows, and complicated COMM communication can also be simplified, concentrate in the lump on the COMM communication and finish.
The purpose of this utility model be achieved in that on valve body concentrate be provided with symmetrically four holes respectively with the drag flow gas inlet pipeline of symmetry, the gas outlet pipeline that backflows is connected with the drag flow gas of two symmetries, anti-fluid inlet and outlet pipeline.Spool is installed in the valve body inboard, and can rotate, but can not two curved channels symmetrically be arranged the steam leak-off valve in-core, and in spool surface of revolution formation four holes symmetrically, there is one-to-one relationship in four holes on these four holes and the valve body.The purpose of design curved channel is in order to reduce the resistance of convection cell.When spool just can be realized the mutual switching of the drag flow gas and the gas that backflows during sideway swivel in valve body, when the spool surface of revolution is sealed on the valve body symmetrically the position in four holes, the drag flow gas and the gas that backflows are separated fully, can not crossfire.
Owing to adopt such scheme, in the air separation plant technological process, realized of the stable switching of drag flow gas with the gas that backflows, concentrate four Kong Yulie symmetrically that are provided with to answer four pipelines to connect on the valve body, simple in structure.
Below in conjunction with drawings and Examples are further specified the utility model.

Fig. 2 is the turn clockwise longitudinal section tectonic maps of embodiment 45 ° time of four-way rotation switching valve spool (2).
Fig. 3 is the longitudinal section tectonic maps that four-way rotates embodiment when switching valve spool (2) is clockwise to rotate 45 ° again.
Backflow gas outlet pipeline backflow gas, drag flow gas inlet and outlet pipeline 6. drag flow gases, the gas exit port pipeline 7. curved channel I of backflowing 8. curved channel II of 1. valve bodies, 2. spools, 3. drag flow gas inlet pipelines 4. among the figure
In the embodiment shown in fig. 1, spool (2) is installed in valve body (1) inboard, can rotate but air tight.Sealing drag flow gas inlet pipeline (3) symmetrically is installed on valve body (1), the gas outlet pipeline (4) that backflows backflow gas, drag flow gas inlet and outlet pipeline (5), drag flow gas, gas exit port pipeline (6) backflows.Curved channel (7) in the spool (2) and drag flow gas inlet pipeline (3), drag flow gas, the gas exit port pipeline (6) that backflows are connected, make drag flow gas by drag flow gas inlet pipeline (3), enter the air separation plant fractionation tower by drag flow gas, the gas exit port pipeline (6) that backflows by curved channel (7) in the spool (2).Curved channel (8) in the spool (2) is connected with the gas that backflows, drag flow gas inlet and outlet pipeline (5), gas outlet pipeline (4) is connected with backflowing, make the gas that backflows that comes from the air separation plant fractionation tower by the gas that backflows, drag flow gas inlet and outlet pipeline (5), by curved channel (8) in the spool (2), gas outlet pipeline (4) is discharged by backflowing.
In embodiment illustrated in fig. 2, spool (2) turns clockwise in valve body (1) inboard, and spool (2) has blocked drag flow gas inlet pipeline (3) 45 ° the time, blocked the gas outlet pipeline (4) that backflows, block the gas that backflows, drag flow gas inlet and outlet pipeline (5), blocked drag flow gas, gas exit port pipeline (6) backflows.Make the drag flow gas and the gas that backflows separate in pipeline separately, and can not crossfire.
In the embodiment shown in fig. 3, Fig. 3 is that Fig. 2 spool (2) turns clockwise and forms 45 ° the time.Curved channel (8) in the spool (2) and drag flow gas inlet pipeline (3), backflow gas, drag flow gas inlet and outlet pipeline (5) is connected, make drag flow gas by drag flow gas inlet pipeline (3), enter the air separation plant fractionation tower by the gas that backflows, drag flow gas inlet and outlet pipeline (5) by the curved channel (8) in the spool (2).Curved channel (7) in the spool (2) and drag flow gas, gas exit port pipeline (6) backflows, the gas outlet pipeline (4) that backflows is connected, make the gas that backflows that comes in the air separation plant fractionation tower pass through the curved channel (7) the spool (2) by drag flow gas, the gas exit port pipeline (6) that backflows, gas outlet pipeline (4) is discharged by backflowing.
Spool (2) rotate to Fig. 1 and embodiment illustrated in fig. 3 in the position time, be working position of the present utility model, certain time period of stay is arranged.Spool (2) is wink to ask the position when rotating to position in embodiment illustrated in fig. 2, makes drag flow gas and the anti-gas body can not crossfire.
Claims (1)
