Abstract
The utility model discloses a reverse osmosis membrane component with excellent sealing property and high strength. The reverse osmosis membrane component comprises a wall cylinder, wherein the wall cylinder is provided with a water outlet end part and a water inlet end part; an inner connecting pipe is arranged in the wall cylinder and is located on one side of the water inlet end part; an O-shaped rubber ring is sleeved on the inner connecting pipe; a stainless steel ring is sleeved on the inner connecting pipe; and the O-shaped rubber ring is sleeved on the stainless steel ring. According to the reverse osmosis membrane component, the stainless steel ring is added between the O-shaped rubber ring and the inner connecting pipe, so that the pressure resistance and the service life of the O-shaped rubber ring are greatly increased, and the sealing property of the reverse osmosis membrane component is effectively ensured.
Description
Technical field
The utility model relates to a kind of high leakproofness reverse-osmosis membrane element.
Background technology
In known technical field, in the rolled film element, O-ring seals generally is used for the inner connection tube spare of diaphragm seal element infiltration water, to prevent that high-pressure feed water from advancing in the infiltration water of people's low pressure, play the stopping time at counter-infiltration system, membrane component moves in pressure vessel assemblies and starting pressure can have to the intensity at O-ring seals place larger compressing, can cause the damage of O-ring seals or the decline of sealing property after using for a long time, the damage of O-ring seals or inefficacy will cause infiltration water concentration to increase, and affect the operating efficiency of membrane component.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of good seal performance and intensity high reverse-osmosis membrane element.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high leakproofness reverse-osmosis membrane element, comprise the wall cylinder with water outlet end and water inlet end, in described wall cylinder and be positioned at into water end one side and be provided with inner connection tube spare, cover has O type rubber ring on the described inner connection tube spare, also cover has stainless steel coil on described inner connection tube spare, and described O type rubber ring sleeve is on stainless steel coil.
The beneficial effects of the utility model are: the utility model is by setting up stainless steel coil between O-ring seals and inner connection tube spare, compressive property and the service life of O-ring seals have greatly been improved, so that the sealing property of reverse-osmosis membrane element has obtained effective assurance.
