The plunger pump series products of prior art, advance more, the independent respectively processing of liquid discharging valve device, the independent installation, the liquid valve adopts the form of steel ball, promptly when the plunger backhaul of plunger pump, liquid backs down steel ball through the feed liquor valve seat and enters the pressure storehouse, at this moment the steel ball of pumping equipment and valve seat are in closed state, when the plunger reverse operation, the steel ball of feeding device and valve base sealing, liquid enters outside the liquid-discharging tube excavationg pump by the extruding force of plunger, thereby finishes a working procedure, action and so forth, open and close by steel ball and valve seat reach unidirectional conducting, realize working continuously of pump, and there has been following deficiency in this pump valve structure:
1, complex structure, supporting component are many, are difficult for processing.
2, the valve seat of this pump is fixedly tapering self-locking, and the maintenance difficulty is big, safeguards inconvenient.
It is a kind of simple and compact for structure that the purpose of this utility model is to provide, and is easy to processing, easy to maintenance, adopts the straight-through type valve seat, is convenient to the high-pressure plunger pump of dismantling, safeguarding.
The utility model is achieved through the following technical solutions:
It is a kind of high-pressure plunger pump, comprise pump head, it is characterized in that the axially concentric processing of pump head is the active chamber of scalariform, plunger and valve seat are installed in active chamber from left to right successively, the outer side wall processing feed liquor through hole of valve seat, the liquid entering hole UNICOM that processes on feed liquor through hole one end and the pump head, the other end opening is at the end wall of valve seat, the valve seat end wall is installed the feed liquor valve plate, mounting spring between feed liquor valve plate and the pump head, the valve seat center is processed with the fluid through-hole that goes out with liquid port UNICOM, goes out liquid discharging valve is installed in the fluid through-hole liquid discharging valve and be installed in mounting spring between the pressure cap of pump head end.
The outer side wall of described liquid discharging valve is processed with slide block, and the valve seat fluid through-hole wall of corresponding slide block is processed with guiding groove, and the slide block card is placed in the guiding groove.
Described liquid discharging valve center is processed with the liquid bath of trapezium structure, and the outside contact position of inner chamber that liquid discharging valve end and valve seat go out fluid through-hole is cone structure.
The center of described feed liquor valve plate 6 has through hole.
The utility model compared with prior art, because this pump has adopted the runner and the valve seat of straight-through type, so just simplified processing technology, supporting required component have been reduced, and with the fixedly tapering latching valve seat of existing pump, changed into and be convenient to dismantle, safeguard the straight-through type valve seat, so have the following advantages:
1, simple and compact for structure, be easy to processing.
2, adopt the straight-through type valve seat, be convenient to dismounting, safeguard.
Describe in further detail below in conjunction with Figure of description:
Fig. 1: the utility model example structure schematic representation.
Among the figure: 1 plunger, 2 joining plates, 3 sealing gaskets, 4 pump heads, 5,10 springs, 6 feed liquor valve plates, 7 valve seats, 8 liquid-discharging tubes, 9 liquid discharging valves, 11 pressure caps, 12 liquid inlet pipes, 13 guiding grooves
As shown in Figure 1, this high-pressure plunger pump, comprise pump head 4, pump head 4 is axially processed the active chamber that is scalariform with one heart, plunger 1 and valve seat 7 are installed in active chamber from left to right successively, the outer side wall processing feed liquor through hole of valve seat 7, the liquid entering hole UNICOM that processes on feed liquor through hole one end and the pump head, the other end opening is at the end wall of valve seat, valve seat 7 end walls are installed feed liquor valve plate 6, mounting spring 5 between feed liquor valve plate 6 and the pump head 4, and valve seat 7 centers are processed with the fluid through-hole that goes out with liquid port UNICOM, go out liquid discharging valve 9 is installed in the fluid through-hole liquid discharging valve 9 and be installed in mounting spring 10 between the pressure cap 11 of pump head end.
The outer side wall of described liquid discharging valve 9 is processed with slide block, and the valve seat fluid through-hole wall of corresponding slide block is processed with guiding groove 13, and the slide block card is placed in the guiding groove 13.
Described liquid discharging valve 9 centre sections are trapezium structure, and the outside contact position of inner chamber that end and valve seat go out fluid through-hole is cone structure.
The center of described feed liquor valve plate 6 has through hole.
In use, this high-pressure plunger pump is combined as a whole by the joining plate 2 and the pump housing, and with liquid inlet pipe 12, liquid-discharging tube 8 links up with other relevant devices, start the motor that links with it, then motor drives plunger 1 motion by bent axle, when plunger 1 outwards moves, motion with plunger 1, make the plunger cavity internal pressure decline of pump head 4 form negative pressure, so the liquid in the liquid inlet pipe 12 under pressure, the active force that overcomes spring 5 backs down feed liquor valve 6, enter along the through hole on the valve seat 7 in the plunger cavity of pump head 4, when plunger 1 ran to the summit, feed liquor valve plate 6 was subjected to spring 5 effects to close valve seat 7 enterprising fluid through-holes, the interior liquid of plunger cavity this moment is in closed state, and suction process finishes; Then along with plunger 1 moves to pump head 4 directions, liquid in the plunger cavity overcomes the pressure of liquid discharging valve 9 and spring 10 under the promotion of plunger 1, liquid discharging valve 9 is moved to opposite side along guiding groove 13, liquid in the trapezoidal liquid bath of liquid discharging valve 9 is discharged, the liquid of discharging enters another device from the liquid port of pump head 4 and the liquid-discharging tube 8 that links with it, run to this summit until plunger, the discharge opeing process finishes, liquid discharging valve 9 resets under spring 10 effects, close the through hole of valve seat 7, so far discharge opeing process finishes, and then carry out next imbibition process, do action and so forth, can form continual liquid output, the utility model is because of having changed the fixedly tapering latching valve seat of existing pump into the runner and the valve seat of straight-through type, so just simplified processing technology, supporting required component have been reduced, reduced processing cost, and be convenient to dismounting and maintenance more, the inner chamber outside that liquid discharging valve 9 ends and valve seat 7 go out fluid through-hole is conical surface seal, increase the sealability that liquid discharging valve 9 and valve seat 7 go out fluid through-hole, guaranteed the functional reliability of integral pump.
