Quick flow-breaking, and ball valve body b can be enable to prevent pair by padding the disengaged unlatching of a7 with the main pad a2 of rubber, rubber side
The abrasion of the main pad a2 of rubber, rubber side pad a7 enable the main pad a2 of rubber, rubber side pad a7 preferably to keep and ball valve body b
Fitting, prevent oil leakage phenomenon.
The method is mainly characterized in that: in the ball valve body b of equipment by be equipped with filter device d come the petroleum to conveying into
The certain filtering of row, and this filter device d is when ball valve switch rotates, because using strainer Assembly rail d3, Assembly rail fixed link
D4 is connect with snap ring a6, is rotated so that it will not follow the rotation of ball valve, is remained the inconvenience of filtering direction, and then make ball valve
The sundries filtered when use will not enter the pipeline other side, to make that only ball valve can be penetrated into petroleum having sundries in oil transportation
The right side of main body b, and being stopped when middle part by the main pad a2 of rubber makes to be influenced by sundries when the subsequent return of equipment, more
Good prevents oil leakage phenomenon.
Problems solved by the invention be traditional ball valve when in use, because of the gap at ball valve assembly, 1, when in use,
Because making to be easy the infiltration because of oil at the assembly of ball valve, causing accumulation at assembly to have sundries, to hold doped with sundries in oil
It easily uses ball valve and occurs phenomena such as oil leak after a certain period of time；2, lead to ball valve when closed, it can be because the gap of assembly cannot
Enough quickly stopped, so as to cause inconvenience, the present invention is combined with each other by above-mentioned component, it enables the invention to realize,
Can by the removable ball valve body that is equipped with collocation sealing cushion device and orientation filter device, 1, can by oil doped with
Sundries exclude in ball valve side, and can prevent the petroleum penetrated into from entering the other side, and equipment can pass through when opening
It is mobile to reduce its abrasion to gasket, enable a device to preferably to prevent ball valve using it is certain when after there is oil leakage phenomenon；
2, equipment passes through the gasket being equipped with, and makes equipment when closed, is able to carry out quick closed cutout, prevents gap seepage flow
The phenomenon that.
