Pressure difference before and after pressure gauge detection filter screen is installed；It clears up filter screen impurity in time according to differential pressure conditions, improves filter efficiency,
The position of flap and valve body contact is sealed using rubber o-ring, since caoutchouc elasticity is not good high to requirement on machining accuracy and very
Sealing easy to implement；Both it had saved processing cost and has in turn ensured sealing effect；Quick-actuating closure structure is used when cavity cap structure designs, and is torn open
It is convenient to unload readily replaceable strainer；Use triangle grip structure easy to disassemble when fastener constructions design and Quick fastening；Handle is set
It should not skid in jail that timing is conveniently grabbed using the hand-type structure design of people, the steady, switching process grabbed, Convenient switch；Chamber lid position
It installs in respect of blow valve, blow valve first can fall pressure releasing remaining inside cavity in filter maintenance, avoid tieing up
Pressure remaining inside cavity is hurted sb.'s feelings when repairing dismounting, reduces security risk when repair.
2, the present invention be a kind of tool there are two the filters of filter passages can be to left and right by rotating handle 180 degree
Two filtration channel commutations, can ensure that fluid uninterruptedly filters, and filter screen replacement another filter screen holding is normal
Working condition；It is typically mounted on the input end of compressor, pump, instrumentation, for removing the impurity in medium, in protective conduit
Equipment part from wearing and blocking, can not only extend the service life of pump and other equipment, but also can guarantee whole system
Safety.
