On dynamic clamping plate.
The clamp system includes：Fishbolt pair, the fishbolt pair be arranged in the fixed clamping plate with it is described
Active clamped plate；Clamping element, the clamping element are arranged in the fishbolt pair.
The clamping element is disk spring.
The heat exchanger assembly includes：The quantity of plate, the plate is two or more；Gasket, the quantity of the gasket
For two or more, the plate is arranged with the gasket interval.
The backwash valve is double-direction control valve.
The double-direction control valve is ball valve or butterfly valve.
The utility model backwash valve unit uses heat-exchanger for a long time, in the micro- stifled situation of heat-exchangers of the plate type
Under, heat-exchangers of the plate type is not dismantled, plate is rinsed using backwash valve, heat-exchangers of the plate type is made to be not easy to plug, dismount cleaning side
Just, maintenance man-hours are reduced, labor intensity is reduced, save unit cost.
Description of the drawings
Fig. 1 is the utility model backwash valve set structure schematic diagram；
Fig. 2 is the utility model backwash valve unit heat-exchangers of the plate type structural schematic diagram.
Specific implementation mode
The utility model backwash valve unit is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model backwash valve unit, including pedestal 10, the setting of multiple heat-exchangerss of the plate type 11 exist
It on pedestal 10, is connected by pipeline 12 between multiple heat-exchangerss of the plate type 11, backwash valve 13 is connected on pipeline.Wherein,
Heat-exchangers of the plate type 11, including：Pillar 6；Fixed clamping plate 1, fixed clamping plate 1 are arranged with the interval of pillar 6；On lead
The both ends of bar 5, top guide bar 5 are connect with fixed clamping plate 1 and pillar 6 respectively, and top guide bar 5 is arranged in fixed clamping plate 1 and pillar 6
Top；The both ends of lower guide rod 9, lower guide rod 9 are connect with fixed clamping plate 1 and pillar 6 respectively, and lower guide rod 9 is arranged in geometrical clamp
The lower part of tight plate 1 and pillar 6；Active clamped plate 4, the top and lower part of active clamped plate 4 respectively with top guide bar 5 and lower guide rod 9
Connection；Heat exchanger assembly, heat exchanger assembly are arranged between fixed clamping plate 1 and active clamped plate 4.
Clamp system, clamp system are connected on fixed clamping plate 1 and active clamped plate 4；Wherein clamp system includes：Folder
Tight bolt pair 8, fishbolt pair 8 are arranged in fixed clamping plate 1 and active clamped plate 4；Clamping element, clamping element setting are clamping spiral shell
In bolt pair 8.Clamping element is disk spring 7.
Heat exchanger assembly includes：The quantity of plate 2, plate 2 is two or more；Gasket 3, the quantity of gasket 3 be two with
On, plate 2 is arranged with the interval of gasket 3.
Backwash valve 13 must be double-direction control valve, can be butterfly valve, ball valve etc., by backwash valve 13 by elbow and
Pipeline, flange etc. and piping connection before heat-exchangers of the plate type 11.Wherein, backwash valve 13 is necessarily mounted at heat-exchangers of the plate type 11
Inlet, 11 exit of heat-exchangers of the plate type can not have backwash valve 13, because on heat-exchanger, heat-exchangers of the plate type
Drain valve can be all set at 11 low spots.Dirt can also be discharged using drain valve after flushing.
