Abstract
The utility model relates to a sealing device which is suitable for the sealing between a tank and a cover of a pressure container, which is characterized in that the sealing device comprises a gas-liquid transfer device (1) which is connected with a compression gas source, and a sealing ring (2) which is connected with the gas-liquid transfer device through a pipeline, wherein the sealing ring is a ring soft sealing body with a hollow structure, and the section of a hollow cavity of the sealing ring is a rectangular structure, auxiliary fins (5) which respectively extend to the direction of a circle center of a sealing ring body and the outer side of the sealing ring body are arranged on an edged orifice of one end of the sealing ring, and an edged orifice on the other end of the sealing ring is equipped with a pipe joint (6) which communicates with the hollow cavity of the sealing ring and the gas-liquid transfer device. The utility model has a good seal effect, can completely solve defects of the sealing device in the prior art that the air and ammonia are mixed in conditions such as a mechanical damage, a manufacturing defect of the sealing ring or running into power failure and the like, thereby an accident occurs. The operation of device is more steady and reliable, the service life is prolonged, and the device is beneficial to improve the production efficiency.
Description
Technical field
The utility model relates to the sealing technique of pressurized container, relates to the seal arrangement of sealing between a kind of suitable pressure volume pot, the lid specifically.The sealing device is specially adapted to the seal arrangement as fabric liquid ammonia finishing jar jar.
Background technique
The main soft sealing structure that adopts injecting compressed air in the annular hollow chamber of leading to double V-shaped open type seal arrangement of sealing between cover and the tank body in the pressurized container of prior art.But if the soft sealing structure of said structure is used for fabric liquid ammonia finishing jar jar as sealing between cover and the tank body, then there is following technical problem: because the medium in fabric liquid ammonia finishing tank is a liquefied ammonia, fabric carries out in the finishing processes in liquefied ammonia, because the gas-liquid of liquefied ammonia conversion, the jar internal pressure, temperature constantly changes, the penetrability of ammonia is extremely strong in addition, encapsulation scheme between cover and tank body is if adopt above-mentioned soft seal device, though can obtain good sealing effect, but because the supercharging carrier of seal ring is a pressurized air, in case run into mechanical deterioration, seal ring manufacturing deficiency or meet by chance the situation such as die that has a power failure takes place, certainly will cause air to mix, have hidden peril of explosion or the gas ammonia incident of overflowing to take place with ammonia.If charge into other inert gas in the seal ring, then attached structure is very complicated, and cost is also higher.Must take new technical measures to carry out the sealing of fabric liquid ammonia finishing jar jar for this reason.
Summary of the invention
The purpose of this utility model is just at existing problem in the above-mentioned prior art, and a kind of seal arrangement that is applicable to sealing between pressure volume pot, the lid is provided.
The purpose of this utility model can realize by following technique measures:
One cover new type sealing device of design of the present utility model is changed to oil pressure with a cover gas-liquid conversion equipment with the air pressure dress, oil is charged into the sealing of carrying out in a kind of special seal ring between cover and the tank body.
The purpose of this utility model can realize by following measure:
The seal arrangement of sealing between pressure volume pot, the lid that is applicable to of the present utility model comprises gas-liquid conversion equipment that is connected with compressed gas source and the seal ring that is connected with the gas-liquid conversion equipment by pipeline, described seal ring is the annular soft seal body of a hollow structure, and the cross section of the hollow cavity of sealing circle is a rectangular configuration; Be provided with the auxiliary wing that outside seal ring body center of circle direction and seal ring body, extends respectively around seal ring one ora terminalis mouth, the pipe joint of communication seals circle hollow cavity and gas-liquid conversion equipment is installed on the edge mouth of the seal ring the other end.
Working principle of the present utility model is as follows:
The utility model is by pressurized air and gas-liquid conversion equipment, the liquid (oil) of certain pressure filled in the hollow cavity of seal ring, and keep certain pressure, and then realize sealing between the cover of fabric liquid ammonia finishing jar jar and the tank body.
The beneficial effects of the utility model are as follows:
The utility model not only has compared to existing technology holds good sealing effect, can fundamentally solve the prior art seal arrangement is running into mechanical deterioration, seal ring manufacturing deficiency or is meeting the situation such as die that has a power failure by chance when taking place, because of air mixes with ammonia, and blast that causes or gas ammonia overflow incident, and the operation that can make equipment is more reliable and more stable, prolonged working life, more helps the raising of manufacturing efficiency.
