Abstract
The utility model relates to a water restriction valve, in particular to a water valve restricting flow (small flow) for RO converse seepage water treatment equipment and filter water equipments. The valve contains a cylindraceous body and a flow-restriction blade. A restriction hole is arranged on the restriction blade. The vertical edge extended from the rear end of the cylindraceous body is connected with the restriction blade. The valve can be made by stretching and impacting sheet metal or by molding plastic material into shape. The utility model has the advantages of simple structure, low cost, convenient installation and easy cleaning.
Description
Technical field:
The utility model relates to a kind of current limliting penstock, especially a kind of current limliting (low discharge) penstock that is applied to RO reverse osmosis water treatment facilities and nanofiltration water treatment facilities.
Background technology:
In existing RO reverse osmosis water treatment facilities and nanofiltration water treatment facilities, generally all be provided with system's flushing pipe and current limliting outlet conduit, on the current limliting outlet conduit, install flow-limiting valve.Existing flow-limiting valve, mainly by the centre be provided with fill chamber 36, be arranged at the current limiting tube 34 in the chamber, valve body 31 and filter membrane 33, the pipe joint 32,35 that two ends are provided with connecting thread constitutes, as shown in Figure 1.Existing flow-limiting valve, mainly have complex structure, cost of manufacture height, install inconvenient, be not easy to shortcoming such as cleaning.
The utility model content:
The purpose of this utility model is the shortcoming at existing flow-limiting valve, provide a kind of simple in structure, cost of manufacture is low, RO machine flow-limiting valve easy for installation, easy cleaned.
The utility model is made of cylindric valve body and constrictor, and metering hole is set on constrictor, and the longitudinal edge edge of extending at valve rear end links to each other with constrictor.
The utility model can be made by the sheet metal stretching and punching, also can be made by the plastic material pressure injection.The external diameter of cylindric valve body cooperates with the internal diameter of current limliting outlet pipe.The aperture of metering hole is generally 0.3-1.5mm.
The utility model, have simple in structure, cost of manufacture is low, easy for installation, be easy to characteristics such as cleaning.Can be applicable in various the RO reverse osmosis water treatment facilities and nanofiltration water treatment facilities, only need be inserted in the current limliting outlet pipe (3/8 or 2/8 pipe) of RO machine and get final product.
Description of drawings:
Fig. 1 is the structure principle chart of the existing little RO machine of plastic cement flow-limiting valve, and Fig. 2 is that the existing little RO machine of plastic cement flow-limiting valve is applied to the block diagram in the water treatment facilities current limliting outlet conduit.
Fig. 3 is the structure principle chart of embodiment, and Fig. 5 is applied to block diagram in the water treatment facilities current limliting outlet conduit for embodiment, and Fig. 4 is the Q portion enlarged drawing of Fig. 5.
Among the figure, 11, water inlet 12, three-way connection 13, flushing valve 14, three-way connection 15, water outlet 16, current limliting outlet pipe 20, embodiment flow-limiting valve 21, cylindric valve body 22, constrictor 23, metering hole 24, flow-limiting valve joint 30, traditional flow-limiting valve 31, current limliting valve body 32, water supply connector 33, screen pack 34, current limiting tube 35, water out adapter 36, fill the chamber.
The specific embodiment:
With reference to Fig. 3, this water purifier flow-limiting valve is made by the sheet metal stretching and punching.Flow-limiting valve comprises cylinder valve body 21 parts and constrictor 22 parts, in the constrictor upper punch metering hole 23 is arranged, and the aperture is 0.4-0.6mm, extends the longitudinal edge edge that is provided with at the cylinder valve rear end and is connected by the moulding of five metals production technology and with constrictor 22 consubstantialities.
With reference to Fig. 4-Fig. 5, present embodiment is applied in the RO machine, only needs this flow-limiting valve is inserted in the current limliting outlet pipe 16 of RO machine get final product, adopts and is with the coupling nut 24 (flow-limiting valve joint) of taper to be installed in flow-limiting valve 20 in the current limliting pipeline 16.Assemble very conveniently, also clean easily.
