Description
Technical field
A kind of expansion drum is the utility model is related to, specifically a kind of bellows expansion drum.
Background technology
The jar structure of bellows expansion at present mainly includes tank body and is arranged on the capsule of tank interior, and wherein capsule is one section one
Section, which is pasted, to be formed, and up big and down small shape is presented in capsule, and capsule bottom port is directly fixed with water inlet pipe and water outlet pipe by flange.It is this
Three defects be present in structure：First, because capsule is that up big and down small shape is presented, therefore placed for the ease of capsule, it is necessary to
Installation through-hole is opened up at the top and bottom of tank body, and setting flange, blind flange, cylinder are needed on the installation through-hole at the top of tank body
The components such as section, can thus have the shortcomings that manufacturing procedure is more, and labor intensity is big and cost is high；Second, because capsule is one section
Paste for one section and form, on the one hand not only processing technology is cumbersome, and expansion rate is small, and be easily pressurized swelling cracking, substantially reduces use
Life-span, on the other hand just because of the shortcomings that expansion rate is small be present by one section of one section of capsule pasted, so need will be whole
Individual tank body volume is done greatly, highly does height, so not only increases cost, and volume is heavy, and space-consuming is big, carries trouble；3rd,
Capsule bottom port is directly to be fixed by flange with water inlet pipe and water outlet pipe, on the one hand due to being that formula directly is fixed by flange to connect
Connect, orientation can not be carried out and freely turned to, be not easy to in-site installation, on the other hand, when capsule bottom port is easily pressurized in outside
Tank interior is retracted, the connection destroyed between capsule bottom port and water inlet pipe and water outlet pipe, so as to influence to use function, shortening uses the longevity
Life.
Utility model content
In view of the above-mentioned problems, the problem of the utility model intends to solve is to provide, one kind is simple and reasonable, cost is low, technique
Simply, the bellows expansion drum that small volume, installation convenient in carrying, expansion rate be good and service life is grown.
To reach above-mentioned purpose, the utility model uses following technical scheme：A kind of bellows expansion drum, including tank body and glue
Capsule, the tank base are fixed with three legs, and the tank base centre position offers an installation through-hole, in the tank body
Portion is provided with a capsule, and the capsule is formed in one, and the capsule is in up-small and down-big structure, and the capsule top is fixed
At the top of the tank body, the bottom of the capsule is fixed in the bottom installation through-hole of the tank body by mounting flange, institute
The centre position for stating mounting flange is provided with a hickey, is located at the capsule bottom end face on the mounting flange upper surface
Place is fixed with a positioning hole plate.
Preferably, the material of the capsule is ethylene propylene diene rubber.
Effective achievement of the present utility model：The utility model is simple and reasonable, and capsule is set and is formed in one, and is in
Up-small and down-big structure, while ethylene propylene diene rubber material is used, as long as on the one hand opening up an installation through-hole in tank base
Capsule installation can be carried out, greatly simplifies the processing technology of tank body, labor intensity is reduced, cost is reduced, on the other hand for glue
Capsule itself, there is the characteristics of technique is simple, expansion rate is big, service life is long, can effectively reduce the making height and system of tank body
Make volume, not only there is the characteristics of occupying little space, convenient in carrying, and further reduce cost.Furthermore capsule bottom passes through solid
Determine flange to be fixed in tank base installation through-hole, and a hickey is provided among mounting flange, orientation freedom can be carried out
Turn to, the in-site installation of very convenient water inlet pipe and water outlet pipe, while be located at capsule bottom end in mounting flange upper surface and be fixed with
A positioning hole plate, capsule bottom port can be effectively prevented to be retracted tank interior when outside is pressurized, it is normal so as to be effectively ensured
Use function, increase the service life.
In summary, the utility model have simple and reasonable, cost is low, technique is simple, small volume, installation carrying side
Just, expansion rate is good and the characteristics of service life is long.
