Motion, so as to promote the rocker 7 to do back and forth movement, realizes that the big pressure water pump is pumped to liquid or steam.
Big pressure water pump provided by the invention, during drawing liquid, the actuating unit 9 promotes the draw point 8 to move, and draw point 8 pushes away
Move the rocker 7 to move, rocker 7 stretches the leather cup 6, and the cavity 61 of the leather cup 6 becomes big, therefore the valve plate 4 and the list
The pressure of the side contacted to valve 5 diminishes, and check valve 5 leaves the input hole 42, and liquid enters from the input port of upper lid 1, from
And realize the drawing liquid process of big pressure water pump；
During liquor charging, the actuating unit 9 promotes the draw point 8 to move, and draw point 8 promotes the rocker 7 to move, and rocker 7 extrudes institute
Leather cup 6 is stated, the cavity 61 of the leather cup 6 diminishes, therefore the pressure of side that the valve plate 4 contacts with the check valve 5 becomes big, single
It is close to the input hole 42 to valve 5, the leakage proof gasket 2 is opened by top, and liquid exports from the through hole 412, it is achieved thereby that big pressure
Power water pump send night process.
Compared with prior art, the beneficial effects of the present invention are：
1st, big pressure water pump provided by the invention, the leather cup is extruded using the rocker of hard, is unlikely to deform, pressure easily can be with
Reach more than 3bar, compared with traditional maximum pressure is only 1.8bar, improve 2/3, solve because stress problems can not pump
The problem of liquor charging body or steam, and service life is grown.
2nd, big pressure water pump provided by the invention, the relative position between rocker and the leather cup is positioned using guide pillar, prevented
The only leather cup deformation, so as to influence the pressure of the big pressure water pump.
3rd, big pressure water pump provided by the invention, the locating dowel are stretched into inside the positioning hole, and extension is covered in described
On through hole and the projection, the through hole is sealed, prevents leakage, it is on the other hand, described raised positioned at the leakage proof gasket and described
Between valve plate, during no pressure, certain gap is provided between the leakage proof gasket and the valve plate, prevents the leakage proof gasket and institute
It is long to state valve plate time of contact, be sticked together, cause pressure can not jack up the leakage proof gasket, so as to can not trickle show
As occurring.
4th, the thickness of big pressure water pump provided by the invention, the cavity bottom and the rocker touching position is more than described
The thickness of cavity side, because rocker and the leather cup contact position often produce deformation, easily it is damaged, the cavity herein
The thickness of bottom and the rocker touching position is more than the thickness of the cavity side, extends the service life of the leather cup.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
