Description
Technical field
The utility model is related to a kind of seal with elastometic washer pressure balance sleeve expansion joints.
Background technology
At present due to conveying hot water high-temperature medium, direct buried non-maintaining setting in district heat supply network, but have
The aerial arrangement in part, or in arrangement piping lane, some piping lanes are limited by space, this had just both required heat distribution pipe network and compensation device resistance
It is small and require fixing rack structure small.Common seal with elastometic washer sleeve expansion joint, can only reduce frictional force, cannot overcome pipe
The blind flange force that road pressure generates, especially heavy gauge tube diameter compensation device also need to repeat to be arranged or increase fixing bracket, significantly
Increase the engineering cost of pipe network.The problem of in the presence of for the above-mentioned prior art, a kind of novel rubber ring of research and design
Sealed pressure balancing sleeve compensator pipe fitting considers the problems of piping lane space, pipe network stress and the single arrangement of rubber ring, avoids mending
Device leakage is repaid, is the problems of in the prior art very necessary to overcome.
Patent content
The purpose of this utility model is to provide seal with elastometic washer pressure balance sleeve expansion joint, and the utility model is on realizing
Stating technical solution used by purpose is：Seal with elastometic washer pressure balance sleeve expansion joint, including core-pipe subassembly, the first housing group
Part, the second outer jacket member, third outer jacket member, wherein three outer jacket members contain left and right guide ring, sealing ring respectively, it is described
Three outer jacket members are separately mounted on core-pipe subassembly, and sealing ring, left guide ring and right guide ring are embedded in three housing groups respectively
In part, three outer jacket members are welded and fixed together.
The compensator carries pressure balance chamber, and the blind flange force for overcoming pressure medium to generate, reduction pushes away support of pipelines
Power is counter balance pocket by the space cavity formed between core-pipe subassembly, the first outer jacket member, the second outer jacket member three；Work as production
When in use, there are the media of pressure for core-pipe subassembly inside cavity for product, just will produce certain blind flange force F1；When medium passes through
Intercommunicating pore on core-pipe subassembly 1 enters in counter balance pocket, then also will produce certain blind flange force F2, and blind flange force in counter balance pocket
F2 is opposite with the directions F1；When F2 and F1 are equal in magnitude, the blind flange force that product is born is theoretically equal to 0, that is, overcomes medium
The blind flange force of generation.
The sealing ring is tetra- rubber seal of Liang Zu.
The rubber ring is O-shaped or X-type or Y type rubber rings.
The outer surface chromium plating of the core pipe.
It is equipped with left guide ring and right guide ring in three outer jacket members, is located at three outer jacket member both sides.
It is independent sealed that two groups of O-ring seals and y-type seal ring constitute four.
Three outer jacket members, guide ring, " two groups of O-ring seals and y-type seal ring combination, constitute combined sealing structure.
A kind of seal with elastometic washer pressure balance sleeve expansion joint provided by the utility model, utilizes rubber seal high pressure
The performance of contracting, high rebound, realizes compensator dynamic sealing, compound seal pressure balance sleeve expansion joint is really achieved non-maintaining.
The beneficial effects of the utility model are：The effect of seal with elastometic washer pressure balance sleeve expansion joint is to utilize compensator
Included counter balance pocket, the blind flange force for overcoming pressure medium to generate reduce the thrust to support of pipelines, the heat of concentrated supply of heating in the city at present
Due to conveying hot water high-temperature medium, direct buried non-maintaining setting in solenoid net, but there are the aerial arrangement in part, or arrangement piping lane
In, some piping lanes are limited by space, this had just not only required heat distribution pipe network and compensation device resistance small but also require compensator to reach to exempt to tie up
Shield.Common seal with elastometic washer sleeve expansion joint, can only reduce frictional force, the blind flange force that pipeline pressure cannot be overcome to generate, especially
It is that heavy gauge tube diameter compensation device also needs to repeat to be arranged or increase fixing bracket.The engineering cost of pipe network is considerably increased,
The problem of in the presence of for the above-mentioned prior art, we design a kind of novel rubber ring combination sealing pressure balance sleeve benefit
Device pipe fitting is repaid, the blind flange force of pipeline pressure generation is not only overcome, and it is vulnerable to solve common single rubber seal, compensator
The problem of leakage.Seal with elastometic washer pressure balance sleeve expansion joint had not only remained the small feature of seal with elastometic washer frictional force, but also knot
The characteristics of having closed rubber seal；" O " type+two groups of Y-shaped rubber seal combination, the case where one group of seal with elastometic washer is failed
Under, another group remains to play sealing function, realizes that compensator dynamic sealing, compound seal pressure balance sleeve expansion joint really reach
To non-maintaining.Particularly with the heat distribution pipe network that the limited caliber in piping lane space is larger, the safe and reliable fortune of compensator is advantageously ensured that
Row, meanwhile, seal with elastometic washer pressure balance sleeve expansion joint additional guiding ring is oriented to more as active operation so that compensator fortune
Row is steady, safe and reliable.The utility model have structure novel, simple installation, easy to use, service life is long, work safety
The features such as reliable.
