摘要：【中文】本发明提供了一种导流盘、碟管式膜元件及其加工工艺，其中，导流盘，包括：导流盘母体；导流盘母体的中心处具有中心孔；导流盘母体的两个导流面均具有密封凹槽，密封凹槽与中心孔同轴心，且密封凹槽位于中心孔的外周，密封凹槽用于镶嵌密封圈；密封凹槽的底部开设有多个通孔，至少一个通孔的孔口处开设有注塑口。如此，通过在将密封圈镶嵌在密封凹槽内时，可以通过注塑口向通孔内注入热塑性弹性材料，在热塑性弹性材料冷却后，镶嵌在密封凹槽内的两个密封圈通过热塑性密封材料连接成一个整体的一体件；如此，在导流盘使用过程中，不会发生密封圈脱落或跑圈的情况。有效保证了密封圈的密封作用，提高了碟管式反渗透膜的使用寿命和污水处理效率。 【EN】The invention provides a flow guide disc, a disc-tube type membrane element and a processing technology thereof, wherein the flow guide disc comprises: a flow guide disc matrix; the center of the flow guide disc matrix is provided with a central hole; the two flow guide surfaces of the flow guide disc parent body are provided with sealing grooves, the sealing grooves and the central hole are coaxial, the sealing grooves are positioned on the periphery of the central hole, and the sealing grooves are used for being embedded with sealing rings; a plurality of through holes are formed in the bottom of the sealing groove, and an injection molding port is formed in the orifice of at least one through hole. Therefore, when the sealing ring is embedded in the sealing groove, the thermoplastic elastic material can be injected into the through hole through the injection molding port, and after the thermoplastic elastic material is cooled, the two sealing rings embedded in the sealing groove are connected into an integral piece through the thermoplastic sealing material; so, in the guiding plate use, can not take place the circumstances that the sealing washer drops or runs the circle. Effectively ensures the sealing effect of the sealing ring, and improves the service life and the sewage treatment efficiency of the disc tube type reverse osmosis membrane.
