Further, the termination of described rocker arm is provided with the nut that is used for fastening flat valve plate, sleeve, the holder of glue bowl and ports valve.
Further, described rocker arm is connected with a crankshaft ﹠ connecting by a slide block away from an end of pump.
Further, described flexible pipe is by one first larynx hoop and pressure regulator valve close communication, by one second larynx hoop and connecting base close communication.
Further, the bolt joint of described pressure regulator valve and pump head is provided with packing ring.
Further, the joint of described pump and pump head, connecting base is respectively equipped with the O RunddichtringO.
The utility model backwater structure has been carried out great simplification, and its outstanding effect is:
(1) the pressure regulator valve direct connection is on pump head, and traditional relatively backwater structure has been saved the pressure regulator valve joint, saves production cost;
(2) use the flexible pipe and the first larynx hoop and the second larynx hoop to carry out backwater, replaced traditional return pipe that advances and connected, saved cost of production, and more succinctly attractive in appearance;
(3) use of flexible pipe can allow the structure of pump head and connecting base simpler than traditional water-supplying chamber and suction stand structure, and material consumption reduces, and has saved cost of production;
(4) whole component part reduces, and has saved assembly cost.
Following constipation closes embodiment's accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.

Embodiment
The water recovery apparatus of the utility model reciprocating pump as shown in Figure 3 and Figure 4, comprises pressure regulator valve 4, and described pressure regulator valve 4 is connected with pump head 1 by bolt 2, and described pressure regulator valve 4 is provided with packing ring 3 with the bolt joint of pump head 1, is provided with out horizontal valve 23 in the described pump head 1; One end of one pump 16 embeds three hole sites that are assembled to described pump head 1, and the other end embeds three hole sites that are assembled to connecting base 8.Described pump 16 is respectively equipped with O RunddichtringO 15 with the joint of pump head 1, connecting base 8; Directly be communicated with by flexible pipe 6 between described pressure regulator valve 4 and the connecting base 8, described flexible pipe 6 is by the first larynx hoop 5 and pressure regulator valve 4 close communication, by the second larynx hoop 7 and connecting base 8 close communication.
But be equipped with slide relative ground one rocker arm 24 in described connecting base 8 and the pump 16, described rocker arm 24 is connected with bent axle 10, connecting rod 11 by slide block 9 away from an end of pump 16, the end that described rocker arm 24 stretches into pump 16 is provided with flat valve plate 17, described flat valve plate 17 is connected with ports valve 21 by sleeve 18, be arranged with the glue bowl holder 19 of width on the described sleeve 18, be arranged with the glue bowl 20 that plays seal action in the described glue bowl holder 19 less than sleeve 18.The termination of described rocker arm 24 is provided with the nut 22 that is used for fastening flat valve plate 17, sleeve 18, the holder 19 of glue bowl and ports valve 21.
During the utility model arrangement works, power source is passed to bent axle 10 by the belt wheel belt with power, bent axle 10 drivening rods 11 and slide block 9, and the piston assembly that drives on the slide block 9 is done straight reciprocating motion.When slide block moved right, because the effect of glue bowl 20 and pump 16 inwall surface friction drag, glue bowl holder 19 did not temporarily move to right, i.e. glue bowl holder 19 produces relative displacements with flat valve plate 17, a gap occurs, and cover letter 18 and ports valve 21 constitute passages, and liquid sucting valve is opened.Piston continues to move to right, and ports valve 21 drives glue bowl holder 19 and moves to right together, goes out horizontal valve 23 and is in closed condition, and ports valve 21 left spaces form vacuum, then will intake to suck the vacuum area that pump head 1 and pump 16 form through connecting base 8 water inlets, and suction is finished; When slide block 9 during to left movement, glue bowl holder 19 wouldn't move to left, glue bowl 20 and 17 sealings of flat valve plate, and the water of ports valve 21 left area is compressed, and then will go out horizontal valve 23 and push open, and water is finished water outlet through pump head 1 pressure regulator valve 4.During backwater, water inlet is directly flowed out from pressure regulator valve 4 backwater holes, directly flows back in the connecting base 8 through flexible pipe 6.
The utility model is vertically connected on pressure regulator valve 4 on the pump head 1, and directly both is linked together by flexible pipe 6, and traditional relatively backwater structure has been saved the pressure regulator valve joint, saves production cost; Use the flexible pipe 6 and the first larynx hoop 5 and the second larynx hoop 7 to carry out backwater, replaced traditional return pipe that advances and connected, more succinctly attractive in appearance, material consumption reduces, and has saved cost of production, and the component part of reciprocating pump integral body reduces, and has saved assembly cost.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technological schemes of forming all drop within the protection domain of the present utility model.
