Utility model content
Therefore, the defects of the purpose of this utility model is to overcome in the prior art, there is provided one kind installation and removal are convenient,
The good reverse osmosis membrane of resistance to overturning.
To achieve these goals, a kind of reverse osmosis membrane of the present utility model, including cylindrical outer casing and filter core, it is described outer
One end of shell is provided with a bottom, and the other end is provided with separable end socket, and the filter core includes the water pipe and bag positioned at middle part
The membrane body on the outside of the water pipe is invested, in the side wall of the water pipe and attached region is wrapped positioned at the membrane body and is provided with
Some water holes, end cap is respectively arranged with the both ends of the membrane body, and the end cap is fixed with the water pipe；At the cylinder bottom
Middle part be provided with through hole, one end of the water pipe passes is provided with screw thread on the through hole and lateral wall, so as to one first
Nut is bolted in the end of the water pipe, and is provided with sealing gasket between first nut and the cylinder bottom；Described
One end of the remote through hole of water pipe is provided with a connecting cylinder, and the end of the connecting cylinder has been threadably secured a cover,
The nut of one bolt is arranged in the connecting cylinder, and the screw rod of the bolt is bolted in after passing through the cover through the end socket
One second nut；A compression spring is provided with the connecting cylinder, one end of the compression spring is withstood on the nut, separately
One end is withstood on the cover.
The madial wall of the end socket is provided with a groove, the cover can enter the groove.
Sealing ring is provided between the end socket and the shell.
Sealing ring is provided between the screw rod and the end socket.
Water inlet and concentrated water outlet are provided with the housing, and the water inlet is located at respectively with concentrated water outlet
The both sides of the membrane body.
Using above-mentioned technical proposal, reverse osmosis membrane of the present utility model, installation and removal are more convenient, and both ends pass through respectively
First nut and the second nut tighten fixation, and compression spring is provided with connecting cylinder, therefore can pass through regulation first
Nut and the position progress that the turning position of the second nut and the compression ratio of regulation compression spring come to filter core in shell are micro-
Adjust, to ensure that it will not shake in shell again, improve the structural stability of product.
