Abstract
A kind of sealed type flange, including the ring flange body made of metal material, the ring flange body is equipped with multiple circumferentially distributed through-holes fixed for bolt, the outside of the through-hole is equipped with the corresponding elastic balloon ring for being fixed on ring flange outer rim, the elastic balloon ring connection is located at the airflow channel in ring flange body, and the airflow channel is communicated in the valve of ring flange body outer end face.After flange is fit into, by the inflation to valve, so that being expanded outside elastic balloon is circumferential, so that the gap between flange and other parts is constantly decreased to zero, so that product has sealing function.
Description
Technical field
The utility model relates to flange technical fields, and in particular to a kind of sealed type flange.
Background technique
Flange is a kind of fastening means, and flanged joint, which refers to, to be connected with each other by flange, gasket, bolt three as one group of group
Close being detachably connected for sealing structure.Flanged joint is because its connection sealing is good, stable structure, intensity are high, easy to use, cost
Low advantage is widely used in building trade, urban water supply, boilers and pressure vessel, petroleum industry, duration, chemical industry, food
The industries such as product industry, fire-fighting, pharmaceutical industry, power station, water conservancy, HVAC.However existing flange needs and gasket mutual cooperation ability
With sealing function, and single flange and do not have sealing function.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of sealed type flange:
A kind of sealed type flange, including the ring flange body made of metal material, the ring flange body are equipped with
Multiple circumferentially distributed through-holes fixed for bolt, the outside of the through-hole is equipped with the corresponding elasticity for being fixed on ring flange outer rim
Air pocket rings, the elastic balloon ring connection are located at the airflow channel in ring flange body, and the airflow channel is communicated in flange
The valve of disk ontology outer end face.After flange is fit into, by the inflation to valve, so that expanded outside elastic balloon is circumferential,
So that the gap between flange and other parts is constantly decreased to zero, so that product has sealing function.
Preferably, the protective ring of protrusion is equipped between the elastic balloon ring and through-hole, the protective ring is for preventing
Occur to scrape and cause elastic balloon ring damaged with elastic balloon ring when through-hole penetrates bolt.
Preferably, the protective ring is connect made of metal material and with ring flange body integral type, simplifies installation
Structure.
Preferably, the protective ring is made of elastomeric material, and outside is fixedly connected with elastic balloon ring.Protective ring is viscous
Patch is fixed on the lower end surface of elastic balloon ring, so that flange has stronger suitable environment.
Preferably, the valve includes the opening for being connected to airflow channel and vent plug corresponding with opening.
The utility model has the following beneficial effects: flange is combined into one with elastic balloon ring, without
Installation flange is combined with gasket, reduce part and installation procedure, even if error furthermore occurs during the installation process in flange,
It only needs to be inflated elastic balloon ring, so that the expansion of elastic balloon ring can have sealing function；Furthermore this product reduces
The volume of elastic balloon ring, and elastic balloon ring through-hole that no setting is required passes through for bolt itself, simplify elastic gas
The structure of capsule ring, it is easy to produce.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of embodiment 1.
Attached drawing 2 is the diagrammatic cross-section under 1 valve closing state of embodiment.
Attached drawing 3 is the diagrammatic cross-section under 1 valve opening state of embodiment.
Attached drawing 4 is the diagrammatic cross-section of embodiment 2.
1 ring flange body, 2 through-holes, 3 elastic balloon rings, 4 airflow channels, 5 valves, 6 protective rings, 7 openings, 8 vent plugs.
Specific embodiment
The utility model is further described in 1-4 and embodiment with reference to the accompanying drawing.
Embodiment 1: a kind of sealed type flange, including ring flange body 1 made of metal material, the ring flange
Ontology 1 is equipped with multiple circumferentially distributed through-holes 2 fixed for bolt, and the outside of the through-hole 2 is equipped with correspondence and is fixed on flange
The elastic balloon ring 3 of disk outer rim, the connection of elastic balloon ring 3 are located at the airflow channel 4 in ring flange body 1, the air-flow
Channel 4 is communicated in the valve 5 of 1 outer end face of ring flange body.After flange is fit into, by the inflation to valve 5, so that
Elastic balloon ring 3 expands outward, so that the gap between flange and other parts is constantly decreased to zero, so that product has
There is sealing function.
The protective ring 6 of protrusion is equipped between the elastic balloon ring 3 and through-hole 2, the protective ring 6 is for preventing in through-hole
2 occur scraping with elastic balloon ring 3 and cause elastic balloon ring 3 damaged when penetrating bolt.The protective ring 6 is by metal material system
At and connect with 1 integral type of ring flange body, simplify the structure of installation.
Embodiment 2: a kind of sealed type flange, including ring flange body 1 made of metal material, the ring flange
Ontology 1 is equipped with multiple circumferentially distributed through-holes 2 fixed for bolt, and the outside of the through-hole 2 is equipped with correspondence and is fixed on flange
The elastic balloon ring 3 of disk outer rim, the connection of elastic balloon ring 3 are located at the airflow channel 4 in ring flange body 1, the air-flow
Channel 4 is communicated in the valve 5 of 1 outer end face of ring flange body.After flange is fit into, by the inflation to valve 5, so that
Elastic balloon ring 3 expands outward, so that the gap between flange and other parts is constantly decreased to zero, so that product has
There is sealing function.
The protective ring 6 of protrusion is equipped between the elastic balloon ring 3 and through-hole 2, the protective ring 6 is for preventing in through-hole
2 occur scraping with elastic balloon ring 3 and cause elastic balloon ring 3 damaged when penetrating bolt.The protective ring 6 is by elastic rubber material
Matter is made, and outside is fixedly connected with elastic balloon ring 3.Protective ring 6 is pasted and fixed on the lower end surface of elastic balloon ring 3, makes to do in the proper way
Orchid has stronger suitable environment.
Obviously, the above embodiments of the present invention is merely to illustrate that examples for clearly illustrating the present invention, and is not
