Description
Technical field
The utility model relates to Split Casing sealing structure field, in particular to a kind of Split Casing sealing structure.
Background technique
Split Casing be compressor frequently with structure, be usually made of upper Split Casing and lower Split Casing, split
Casing installation is linked into an integrated entity upper and lower two Split Casings by bolt on side, split as compressor pressure ratio is higher and higher
Leakage problem of the casing on installation side is also more and more significant, solves Split Casing installation side leakage problem and asks as urgently to be solved
Topic.In the prior art, it in order to reduce leakage problem, is opened around the bolt connecting hole on the contact surface on Split Casing installation side
Slot reduces installation side contact area, to improve leakproofness.But and the split face of Split Casing be not implemented all seal, with pressure
Mechanism of qi pressure ratio is higher and higher, still remains leakage problem on the installation side of Split Casing.
Summary of the invention
The utility model provides a kind of Split Casing sealing structure, with solve the problems, such as it is existing at least one.
In order to achieve the above object, the utility model adopts the following technical solution:
A kind of Split Casing sealing structure, including Split Casing, the Split Casing include that upper Split Casing is split under
Casing, the upper Split Casing and the lower Split Casing be provided with installation side, by bolt will the upper Split Casing and
The lower Split Casing connection, which is characterized in that
Conduit is radially offered on the installation side, one end of the conduit is provided with the first opening, other end setting
There is the second opening, filler is added in the conduit, the thermal expansion coefficient of the filler is higher than the Split Casing.
The utility model has the beneficial effects that the Split Casing sealing structure of the utility model, by installation side along diameter
To conduit is offered, the setting of conduit both ends is open, and adds filler in the channel, and the thermal expansion coefficient of filler is higher than split
Casing, filler are heated by high pressure-temperature air-flow and are expanded, and realize the sealing of Split Casing, improve sealing effect.
Detailed description of the invention
The drawings herein are incorporated into the specification and forms part of this specification, and shows and meets the utility model
Embodiment, and be used to explain the principles of the present invention together with specification.
Fig. 1 is the utility model Split Casing sealing structure general illustration；
Fig. 2 is the A direction view of Fig. 1；
Fig. 3 is the installation side schematic diagram of the utility model Split Casing sealing structure；
Fig. 4 is the P-P direction view of Fig. 3.
Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.
As shown in Figures 1 to 4, the Split Casing sealing structure of the utility model, comprising: Split Casing.
Specifically, upper Split Casing 1 is under as shown in Figure 1, Split Casing includes upper Split Casing 1 and lower Split Casing 2
Split Casing 2 is provided with installation side 3, is fixedly connected with upper Split Casing 1 with the installation side 3 of lower Split Casing 2 by bolt.
In the present embodiment, it is opened around the bolt connecting hole on the contact surface on upper Split Casing 1 with the installation side 3 of lower Split Casing 2
Slot improves leakproofness to reduce the contact area on installation side 3.
Further, it installs on side 3 and radially offers conduit 31, one end of conduit 31 is provided with the first opening 32, another
End is provided with the second opening 33, and filler 4 is added in conduit 31, and the thermal expansion coefficient of filler 4 is higher than Split Casing.
As shown in Figure 3, it is to be understood that air-flow flows the (arrow direction in Fig. 3 along airflow direction in Split Casing
For airflow direction), the pressure and temperature of gas increases under blade effect, and high temperature and high pressure gas enters slot by the first opening 32
Road 31 flows back to Split Casing sprue from the second opening 33, filler 2 is added in conduit 31, and filler 2 is high by high pressure
Warm air heating expands, and Split Casing and the sealing of lower Split Casing two parts contact surface, improve sealing effect in realization.
The Split Casing sealing structure of the utility model, by radially offering conduit 31, conduit 31 on installation side 3
Both ends setting opening, and filler 4 is added in conduit 31, the thermal expansion coefficient of filler 4 is higher than Split Casing, filler 4
It heats and expands by high pressure-temperature air-flow, realize the sealing of Split Casing, improve sealing effect.Split Casing sealing knot
Structure, structure is simple, and sealing effect is more preferable.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, the change that can be readily occurred in
Change or replace, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with described
Subject to scope of protection of the claims.
