Provided with screw hole at stepped hole and two；The upper surface of base 1 is provided with five groups of uniform stepped holes, and stepped hole bottom is provided with annular groove, ring
Large sealing packing ring 6 is placed in groove, it is middle to be connected with the profound blind hole in side；Oil guide groove and equal everywhere is provided with base at every group of stepped hole
The screwed hole of cloth；By hold-down bolt 4, screw hole is connected waist type groove everywhere with the upper surface of base 1 everywhere on outer cover 2；Outside outer cover 2
Circle side is arranged with groove everywhere, and cylinder inner bottom part is provided with boss；Plug is stepped cylindrical structure, and big cylindrical end face is provided with step
Hole, small column are provided with annular groove, place small sealing ring 5 in annular groove, the big cylindrical end face of plug 3 is placed on the endoporus bottom of outer cover 2.
The base 1 is connected by screw hole at the stepped hole of side and two with oil connection；
Described big one end in waist type groove one end of outer cover 2 is small.
The large sealing packing ring 6 seals with part end face, and small sealing ring 5 realizes sealing in hole in piece part.
Beneficial effects of the present invention：The utility model can effective retaining element, making it, oil-through-hole is accurately aimed at therewith, and
With good sealing, ensure that part realizes part voltage-withstand test under logical oil condition, multiple parts can be installed while entered
The quiet oil test of row, realize part quick-clamping, dismounting.The utility model can be realized by the structure of minor modifications closure gasket groove
The popularization and application on similar magnetic valve part.

Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of quiet oil pressure pressure test quick change frock of electromagnetic shut-off valve, as shown in figure 1, including base 1, outer cover 2, plug 3,
Hold-down bolt 4, small sealing ring 5, large sealing packing ring 6；
The side of base 1 is provided with profound blind hole, and aperture is provided with screw hole at stepped hole and two, passes through stepped hole and screw and oil
Pipe joint connects；The upper surface of base 1 is provided with five groups of uniform stepped holes, middle to be connected with the profound blind hole of left end, stepped hole bottom
Provided with annular groove, large sealing packing ring 6 is placed in annular groove, be bonded during use and seal with part；Set on base 1 at every group of stepped hole
There is oil guide groove, when dismantling part, the oil that inside is left can flow out from oil guide groove；The bottom surface of outer cover 2 is provided with waist uniform everywhere
Type groove, the big one end in waist type groove one end is small, and the quick disassembly and installation of outer cover is realized by rotation；2 cylindrical side of outer cover is symmetrically set
There is groove everywhere, for observing whether part in use has oil leak, permeability；Outer cover 2 is connected by hold-down bolt 4 and base 1
Connect；The stepped hole in the big cylindrical end face of plug 3 coordinates with the boss of the endoporus bottom of outer cover 2, and placement is small in annular groove on the small column of plug 3
Sealing ring 5, sealing function is realized by coordinating with inner bore of part.
During use, comprise the following steps that：
The first step：Base is lain in into work top, oil pipe is connected with oil-through-hole；Sealing ring is installed in its annular groove,
Part is placed on sealing ring and is directed at oil-through-hole；
Second step：Sealing ring is installed in plug annular groove, plug is loaded to the logical oil pocket oral area of part, it is ensured that load；
3rd step：Outer cover is covered on outside part, and it is bonded with base, hold-down bolt is screwed into bottom by its profiled holes
Seat screwed hole is simultaneously tightened；
4th step：By specific pressure and time logical oil, oil leak is seen whether；
5th step：After pressure-resistant end, gently loosered a bolt and (need not backed out) with allen wrench；
6th step：Outer cover is rotated clockwise, you can remove outer cover；
