Description
Technical field
Hydraulic seal technical field is the utility model is related to, specially a kind of hydraulic machinery seal being conveniently replaceable.
Background technology
Conventional self-sealing compact type hydraulic seal is mainly ○-shaped seal ring, circular seal ring and square seal ring
Deng they have the advantages that simple in construction, easily fabricated, cost is cheap, therefore they are extensive uses in Hydraulic Power Transmission System
Moving sealing element and static seal element.They generally produce 10-25% radial compression deformation in seal groove, and
Sealing surfaces are produced and initially contact stress higher, so as to prevent the leakage of no pressure liquid.
Due to having larger compression when synthetic rubber matter self-sealing compact type hydraulic seal works, therefore its is quiet
Frictional resistance is especially big, is usually more than twice of its kinetic frictional resistances.So big static friction force passes in some low-pressure hydraulics
Low pressure certainly will be caused to creep and the bad phenomenon such as operating difficulties in dynamic system, this is exactly self-sealing compact type hydraulic seal very little
The reason for being used alone as dynamic seal.
But some drawbacks in use be present in traditional hydraulic machinery seal, such as：
1st, traditional hydraulic machinery seal is due to being that integral cast forms, and is needed when changing and installing by hydraulic packing
Part is fixed on hydraulic stem using other utensils could further carry out installation replacing, the replacing of hydraulic seal is installed very not
It is convenient.
2nd, traditional hydraulic seal can only used aloned, can not when needing to use multiple seals to carry out continuous sealing
Enter to be about to seal and stack sealing well, make sealing effectiveness poor.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic machinery seal being conveniently replaceable, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides following technical scheme：A kind of hydraulic machinery sealing being conveniently replaceable
Part, including socket end, tightening sleeve, fastening end and inserted terminal, the socket end upper inside wall is fixedly welded with inner limited block, described
Socket end inwall side is uniformly installed with two the first sealing rings, and the socket end inwall is fixed away from inner limited block one end
First sealing gasket is installed, the socket end bottom is fixedly welded with inserted terminal, and the inserted terminal outer wall is close to socket end one end
The second sealing gasket is installed with, the inserted terminal outer wall side is installed with the second sealing ring, and the inserted terminal bottom is consolidated
Surely fastening end is welded with, the fastening end external stability is provided with external screw thread；Internal thread is fixedly installed inside the tightening sleeve.
Further, it is threadedly coupled between the tightening sleeve and fastening end by internal thread with external screw thread.
Further, the inserted terminal outer wall is fixedly welded with outer limited block between two the second sealing rings.
Further, it is fixedly installed tip with tightening sleeve bottom at the top of the socket end.
Further, the inserted terminal size matches with socket end size.
Compared with prior art, the beneficial effects of the utility model are：
1st, fastening end is secured firmly to above rod member to be sealed by using tightening sleeve, is easy to user to hydraulic press
The replacing installation of tool seal.
2nd, matched by inserted terminal size and socket end size, enabled a user to two identical the utility model
Superposition installation, for the component that some need to use multiple seal continuous sealings, the utility model can possess outstanding
Sealing effectiveness.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of hydraulic machinery seal being conveniently replaceable,
Including socket end 1, tightening sleeve 8, fastening end 9 and inserted terminal 12, the upper inside wall of socket end 1 is fixedly welded with inner limited block 2,
The inwall side of socket end 1 is uniformly installed with two the first sealing rings 4, and the inwall of socket end 1 is away from inner limited block 2
One end is installed with the first sealing gasket 3, and the bottom of socket end 1 is fixedly welded with inserted terminal 12, the outer wall of inserted terminal 12
The second sealing gasket 6 is installed with close to the one end of socket end 1, the outer wall side of inserted terminal 12 is installed with the second sealing ring
7, the bottom of inserted terminal 12 is fixedly welded with fastening end 9, and the external stability of fastening end 9 is provided with external screw thread 11；The receipts
Internal thread 10 is fixedly installed inside tight set 8.
