The sealing of oil machine part can be bolted sealing plate by the connecting hole on end face to be sealed.But it is individual
The structure of some parts is very special, and end face does not have connecting hole, this just needs to be sealed using special means, this gives me
Being sealed property test the difficulty that brings, these parts are sealed to urgent need to solve the problem.
Utility model content
The purpose of this utility model is that overcoming the deficiencies of the prior art and provide a kind of diesel engine part inner cavity water pumping use
Sealing tool can complete the sealing of the inner cavity of special diesel engine part, and seal tightness test is enable easily to carry out.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of diesel engine part inner cavity water pumping sealing tool, is connected on the part that need to be pumped, it is characterised in that: described
Sealing tool include cover board, pressing plate, snap ring, sealing ring, stud, nuts and washers；The pressing plate is placed on described zero
In the one side wall of the lumen orifice of part, the sealing ring cuff fits in institute in the periphery of the snap ring together with the snap ring
It states on another side wall of the lumen orifice of part, the cover board adheres on the outside of the snap ring and sealing ring, the stud
One end connects the cover board, and the other end is connect by the nuts and washers with the pressing plate, and the snap ring and sealing ring is tight
It is thickly compressed between the cover board and the outer wall of part, to complete the sealing to the lumen orifice of the part.
Further, the sealing ring is V-shaped seal ring, and the snap ring is in the V-groove of the sealing ring.
Further, the through-hole passed through to the stud is offered on the pressing plate.
Further, the threaded hole to connect with the stud is provided on the cover board.
Further, the respective quantity more than one of the stud, nuts and washers.
Compared with prior art, the technical effect of the utility model is as follows:
1) the utility model can still carry out the lumen orifice of diesel engine part in the case where end face does not have connecting hole
Sealing, to complete the leakage test of diesel engine part.
2) the sealing tool structure is simple, easy to operate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the usage state diagram of the utility model.

The through-hole that hook bolt 5 passes through.For 4 cuff of sealing ring in the periphery of the snap ring 3, the sealing ring 4 is V-shaped seal ring,
In the V-groove of the sealing ring 4, the sealing ring 4 fits in the part P snap ring 3 together with the snap ring 3
On another side wall of lumen pore.The cover board 1 adheres on the outside of the snap ring 3 and sealing ring 4, be provided on the cover board 1 to
The threaded hole being connect with the stud 5.Described 5 one end of stud connects the cover board 1, and the other end passes through the nut
6 and washer 7 connect with the pressing plate 1, the snap ring 3 and sealing ring 4 are closely compressed on the outer of the cover board 1 and part P
Between wall, to complete the sealing to the lumen orifice of the part P.Stud 5, nut 6 and the respective quantity of washer 7
More than one.
The specific installation method for please referring to Fig. 1 the utility model is as follows:,
By 3 sets of snap ring in sealing ring 4, then by pressing plate 2, stud 5, nut 6, washer 7 and cover board 1 snap ring
3 and sealing ring 4 be tightly attached to the outer wall surface of part P, rotating nuts 6 tense stud 5, are close to the compression of cover board 1 with part P
Snap ring 3 and sealing ring 4, to play sealing effect to the lumen orifice of diesel engine part P.
Experiments verify that the limitation of design of part can be made up with sealing tool described in the utility model, it is being not required to
In the case where wanting other conditions, the sealing of various diesel engine parts is completed, it is not only simple to operate, but also efficiency is improved,
It can facilitate to make to pump test, favorably accomplish.
