For solving above-mentioned technical problem, technical solution adopted in the utility model is: a kind of Portable type sea water desalination device, including connecting the pump housing having drive end bearing bracket and rear end cap, the two position three-way valve of intracavity above the pump housing, piston below the pump housing, water inlet pipe in rear end cap and outlet pipe, overflow valve above drive end bearing bracket and the pump housing, drain pipe on the pump housing and recovery tube, flexible member is set gradually at the piston rod of described drive end bearing bracket, three groups of y-type seal rings and three groups of retainer ring, three groups of y-type seal rings and three groups of retainer ring are arranged alternately together.

This utility model uses the Portable type sea water desalination device designed by technique scheme, by existing sea water desalinating unit is improved perfect, flexible member has been set gradually at front end shell piston rod, three groups of y-type seal rings, three groups of retainer ring, high-voltage energy-saving pump is in the course of the work, after piston rod and y-type seal ring contact wear, flexible member can apply active force to briquetting automatically, indirectly by big for the support of y-type seal ring opening, further with plunger rod contacts, extend the service life of y-type seal ring, improve the reliability of high-voltage energy-saving pump；The pump housing have employed loss of weight design, and weight reduces 25%；Piston rod is supported by the collar of three groups of high-abrasive materials, prevents piston rod from swinging；Piston movement can manually or driven by motor, it is ensured that the using effect of sea water desalinating unit.This utility model compact conformation, easy to carry.

Accompanying drawing explanation

Fig. 1 represents the structural representation of this utility model Portable type sea water desalination device.

Detailed description of the invention

Below in conjunction with the accompanying drawings the structure of this utility model Portable type sea water desalination device is illustrated.

Seeing Fig. 1, this utility model Portable type sea water desalination device, including the pump housing 16, the top of the pump housing 16 is provided with drain pipe 15 and recovery tube 14, and connecting on the pump housing 16 has drive end bearing bracket 18 and rear end cap 11, and the top intracavity of the pump housing 16 is provided with two position three-way valve 13.Being provided with piston 5 in the lower section of the pump housing 16, be provided with sealing ring 6 between piston 5 and the pump housing 16, the piston rod 1 of piston 5 is connected fixing through drive end bearing bracket 18, piston rod 1 with piston 5 by securing member 7.Being provided with water inlet pipe 10 and outlet pipe 9 on rear end cap 11, water inlet pipe 10 is controlled water inlet by the water feeding one-way valve 12 on rear end cap 11, and outlet pipe 9 is controlled water outlet by the water one-way valve 8 that goes out on rear end cap 11, the overflow valve 17 above drive end bearing bracket 18 with the pump housing 16.Flexible member 2 is set successively in the junction of piston rod 1 with drive end bearing bracket 18, three groups of y-type seal rings 19 and three groups of retainer ring 4, flexible member 2 is compressed by briquetting 3, together with three groups of y-type seal rings 19 are arranged alternately with three groups of retainer ring 4, flexible member 2 can be compression spring or other be capable of the flexible member of said function.High-voltage energy-saving pump is in the course of the work, after piston rod 1 and y-type seal ring 19 contact wear, flexible member 2 can apply active force to briquetting 3 automatically, indirectly by big for the support of y-type seal ring 19 opening, contact with piston rod 1 further, extend the service life of y-type seal ring 19, improve the reliability of high-voltage energy-saving pump.Outlet pipe 9 of the present utility model is connected with the water inlet end of RO film (not shown), and recovery tube 14 is connected with the concentrated water drainage water pipe of RO film.

This utility model, when piston rod 1 moves right, drives piston 5 to move right, and the right side pump chamber of piston 5 forms malleation, and water feeding one-way valve 12 is closed, and sea water backs down out water one-way valve 8, enters reverse osmosis membrane (RO film) and carries out desalination process.Simultaneously, on the right side of pump chamber the sea water of band malleation through channeling at the right-hand member of two position three-way valve 13 spool, make the spool of two position three-way valve 13 to left movement, form passage, highly pressurised liquid (dense water) recovered pipe 14 after reverse osmosis membrane processing flows into the pump chamber on the left of piston 5 by this passage, thus play the effect of required high pressure on the right side of partial equilibrium piston 5, i.e. recovery section energy, so that operation force reduces.

This utility model, when piston rod 1 is to left movement, drives piston 5 to form negative pressure to left movement, the right side pump chamber of piston 5, and sea water under atmospheric pressure, backs down water feeding one-way valve 12, enters the right side pump chamber of piston 5.Meanwhile, go out water one-way valve 8 also due to pump chamber negative pressure and close.On the left of pump chamber, forming malleation due to the motion of piston 5, dense water is through the left end of passage to two position three-way valve 13 spool, under the dual function of two position three-way valve 13 spool band malleation sea water and right side negative pressure to the left, moving right, form passage, dense water is outside this passage is by drain pipe 15 excavationg pump.
