The problem of sealing ring is damaged in journey, improves sealing, greatly increases the overall performance of engine, practical and convenient, operation
Steadily, service life is long, it is easy to promote.
The technical scheme that the utility model is used is：A kind of pressure valve with filtration, it includes valve body, valve
Seat, core assembly, the valve body include the valve protecgulum and valve bonnet being mutually permanently connected, and valve protecgulum and valve bonnet junction are set
The diaphragm being fixedly connected is equipped with, diaphragm is set for double-decker, and the side that valve protecgulum is located at valve seat is provided with oil inlet, oil inlet
Place is provided with filtration, and filtration is sheathed on valve seat, and setting on cellular filter screen, valve seat is provided with filtration
Have to be provided with annular groove, annular groove on the left of oil-out, valve seat and be arranged with O-ring seals, core assembly passes through diaphragm and valve body
It is connected with each other, core assembly includes steel ball, steel ball seat and spring base, and steel ball is with steel ball seat by setting spring I to interfix
Connection, steel ball seat is mutually permanently connected with spring base；It is provided with spring installation position, spring installation position and sets in the valve bonnet
There are spring II, spring II to be mutually permanently connected with described spring base；It is provided with the right side of the valve seat and the matching of described steel ball
Chamfering structure is provided with the inside of the annular projection of conjunction, annular projection；It is provided with and is adapted with described steel ball in the steel ball seat
Groove, be provided with the spring groove being adapted with the spring I in groove.
The beneficial effects of the utility model are：, should be with the pressure valve of filtration due to taking above-mentioned technical proposal
It is simple and reasonable, by setting filtration at oil inlet, the fuel oil for flowing into pressure valve is filtered, inflow is improved
Start the quality of fuel oil, while by way of being set on valve seat and being arranged O-ring seals on annular groove, it is to avoid in installation process
The problem of middle sealing ring is damaged, improves sealing, greatly increases the overall performance of engine, practical and convenient, and operation is flat
Surely, service life is long, it is easy to promote.
