Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, Fig. 2 and Fig. 3, solid preparation fluid bed air inlet air-flow unidirectional flame proof valve of the present utility model, bag
Include left cavity 1, left retainer ring cavity 2, right cavity 3, right retainer ring cavity 4, spool 5, spool guide post 6, left silica gel ring 7, the right side
Silica gel ring 8, Gask-O-Seal 9, sensor 10, sensing connecting rod 11 and stage clip 12.
Left cavity 1 and right cavity 3 are connected between fluid bed air inlet pipeline after sealing connection.Specifically, left cavity 1 is left
Side flange, right cavity 3 right flange are for the connection of air-flow flame proof valve with fluid bed admission line.Left cavity 1 right flange, the right side
On the left of cavity 3, flange connects fixing by multiple hex bolts 13 and hex nut 14.3rd sealing ring 15 for left cavity 1 with
The sealing of right cavity 3 junction.
Left retainer ring cavity 2 is fixed in left cavity 1 by left standing screw 16, and right retainer ring cavity 4 is fixing by the right side
Screw rod 17 is fixed in right cavity 3.
Left retainer ring cavity 2 has left level trough, and right retainer ring cavity 4 has right level trough.Left silica gel ring 7 is by left card
Ring 18 is fixed on the notch of left level trough, and right silica gel ring 8 is fixed on the notch of right level trough by right snap ring 19.
The left end of spool guide post 6 seals the left level trough of insertion, after right-hand member passes right silica gel ring 8 after left silica gel ring 7
Seal and insert right level trough.Spool 5 is welded on spool guide post 6, thus left and right moves freely together.
Gask-O-Seal 9 is fixed in left cavity 1 by food stage glue, and just to spool 5.
Sensing connecting rod 11 is vertical, and its top passes and is fixed on the left retainer ring mounting seat 20 bottom left retainer ring cavity 2,
And it being revealed in left level trough, this top is round and smooth, facilitates spool guide post 6 to oppress and move downward.
The bottom of sensing connecting rod 11 is through being fixed on the left cavity mounting seat 21 bottom left cavity 1.One end of stage clip 12
Pushing and pressing sensing connecting rod 11, the other end pushes against left cavity mounting seat 21.When fluid unit blast terminates, and fluid unit is again
During normal operation, stage clip 12 can make sensing connecting rod 11 automatically restore.
First sealing ring 22, sensing connecting rod 11 and left chamber are set between sensing connecting rod 11 and left retainer ring mounting seat 20
Second sealing ring 23 is set between body mounting seat 21.
Sensor 10 is fixed on the lateral wall of left cavity 1 by sensor installation seat 24, and is positioned at sensing connecting rod 11
Immediately below bottom.
When fluid bed is properly functioning, air-flow moves right, and band movable valve plug 5 moves right, when spool guide post 6 top is to the right side
During retainer ring cavity 4 end, spool 5 motion stops, and now spool 5 is exactly in the centre of the left cavity of flame proof valve 1 and right cavity 3
Position, now air-flow can be walked around spool 5 and enters in fluid unit.As it is shown on figure 3, when exploding in fluid unit
Time, a powerful gas shock ripple can be produced in equipment, this gas shock ripple direction and air-flow direction of motion time properly functioning
On the contrary, this gas shock ripple promotes spool 5 to left movement, and when spool 5 pushes down Gask-O-Seal 9, spool 5 motion stops, valve
Formed between core 5 and Gask-O-Seal 9 and seal.Spool guide post 6 along with spool 5 together to left movement, when spool 5 pushes down annular
During sealing gasket 9, sensing connecting rod 11 is oppressed and ejected to spool guide post 6, and between sensing connecting rod 11 and sensor 10, gap becomes
Little, it is possible to make sensor 10 obtain induced signal, system for prompting runs and stops, it is to avoid the aggravation of blast.Due to spool 5 and annular
Between sealing gasket 9 formed seal, make flame proof valve left and right sides equipment formed cut off, it is to avoid the auxiliary devices such as airhandling equipment because of
Explode and cause damage.
Above example is the most for illustration of the utility model, rather than to restriction of the present utility model, relevant technical field
Technical staff, in the case of without departing from spirit and scope of the present utility model, it is also possible to make various conversion or modification, because of
The technical scheme of these all equivalents also should belong to category of the present utility model, should be limited by each claim.
