Abstract
The utility model relates to a central tube connector of a reverse osmosis membrane element, which is a hollow tube. External circle surfaces of both ends of the hollow tube are provided with O-shaped grooves, and the external circle surface of the middle part of the hollow tube is provided with a stop catch protuberance. Because the external circle surface of the middle part of the connector is additionally provided with the stop catch protuberance, when a central tube of a reverse osmosis membrane is inserted into the middle part of the connector, the stop catch protuberance can prevent the position of the connector from deviating, ensure the distances of the connector in two central tubes to be identical, and avoid the defects of water leakage, even being unconnected because the connector is not tightly connected with the central tube. In addition, the positioning action of the stop catch protuberance is convenient for workers to install and assemble the reverse osmosis membrane element, so that the installation efficiency is improved.
Description
Technical field
The utility model relates to a kind of pipeline connecting parts, relates in particular to a kind of reverse-osmosis membrane element central tube connector.
Background technology
At present, the reverse-osmosis membrane element central tube connector that uses on the market is the column type ABS pipe of a hollow, when needs link together two reverse osmosis membranes, as long as the two ends of connector are inserted respectively in the central tube of two reverse osmosis membranes, when inserting central tube, connector may a length of side in two central tubes, short on one side, even tube connector is all inserted in the central tube, to such an extent as to can not play the effect of connection, even can cause and leak.
The utility model content
The purpose of this utility model is for providing a kind of reverse-osmosis membrane element central tube connector, when using this connector to connect two reverse osmosis membranes, the link position of connector can not be offset, thereby avoids connecting the shortcoming that does not closely cause reverse osmosis membrane to leak even lose the connection effect.
To achieve these goals, a kind of reverse-osmosis membrane element central tube connector of the present utility model adopts following technical scheme:
A kind of reverse-osmosis membrane element central tube connector is a hollow tube, has O type circle groove on the external peripheral surface of the two ends of this hollow tube, and it is characterized in that: the external peripheral surface of described hollow tube middle part has stop projection.
Described stop projection is the protruding point that distributes along the hollow tube external peripheral surface.Described protruding point has three at least.
Described protruding point has six, and these six protruding points evenly distribute along the hollow tube external peripheral surface at interval.
Described stop projection is along hollow tube external peripheral surface protruding ridge spaced apart.
Described protruding ridge has three.
Described stop projection is the ring-like projection around the hollow tube external peripheral surface.
The cross sectional shape of described ring-like projection is taper.
Adopt technique scheme, because the external peripheral surface in the middle part of connector increases stop projection, when the central tube of reverse osmosis membrane is inserted into the middle part of connector, described stop projection can stop the connector position skew, guarantee that the distance of connector in two central tubes is identical, avoided connector to be connected and closely and easily do not caused the shortcoming of leaking even not connecting with central tube; In addition, the positioning action of stop projection has also made things convenient for the installation cooperation of workman to reverse-osmosis membrane element, has improved installation effectiveness.

Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2;
Fig. 3 is the structure cutaway view of embodiment 3.
Fig. 4 is connector and central tube connection diagram.
Among the figure:
1, hollow tube 2, external peripheral surface 3, O type circle groove 41, stop projection 41, protruding point 42, protruding ridge 43, ring-like projection 01, connector 02, central tube
The specific embodiment
As shown in Figure 1, a kind of reverse-osmosis membrane element central tube connector of present embodiment is a columniform hollow tube 1, adopts the ABS material.On the two ends of this hollow tube 1 external peripheral surface 2, respectively have two O type circle grooves 3, install O type circle in the O type circle groove 3 and be used for sealing when connector is connected with central tube, avoid leaking.In addition, external peripheral surface has stop projection 4 in the middle of hollow tube 1.In the present embodiment, described stop projection is external peripheral surface 2 even six protruding points 41 spaced apart along hollow tube 1.
As shown in Figure 2, a kind of reverse-osmosis membrane element central tube connector of present embodiment and embodiment 1 different place is, described stop projection is along the external peripheral surface 2 of hollow tube 1 three protruding ridges 42 spaced apart.
As shown in Figure 3, a kind of reverse-osmosis membrane element central tube connector of present embodiment and embodiment 1 different place is that described stop projection is the ring-like projection 43 around the external peripheral surface 2 of hollow tube 1.The cross sectional shape of described ring-like projection 43 is taper.
As shown in Figure 4, when the connector 01 of above-mentioned arbitrary embodiment is connected with the central tube 02 of reverse osmosis membrane, because the external peripheral surface in the middle part of connector 01 increases stop projection 4, when the central tube 02 of reverse osmosis membrane is inserted into the middle part of connector, described stop projection 4 can stop the connector position skew, guarantee that the distance of connector 01 in two central tubes 02 is identical, avoided connector to be connected and closely and easily do not caused the shortcoming of leaking even not connecting with central tube; In addition, the positioning action of stop projection has also made things convenient for the installation cooperation of workman to reverse-osmosis membrane element, has improved installation effectiveness.
The above-mentioned specific embodiment is exemplary, is to be restriction to this patent protection domain in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope of this patent protection.
