Fig. 2 for described in the utility modelly advance, the structural representation of liquid discharging valve group when discharge opeing.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
Described in the utility modelly advance, the discharge opeing valve block structure, as shown in Figure 1 and Figure 2, the valve plate 6 that comprises valve seat 3, is arranged in the spool 2 at valve seat 3 centers and is arranged at valve seat 3 tops, described valve seat 3 can be done moving of relative valve plate 6 on axially along spool 2, this valve seat 3 is provided with a plurality of through holes 9, described through hole 9 one ends are positioned at valve seat 3 tops, and an end is positioned at valve seat 3 bottoms.Described a plurality of through hole 9 is that the center is symmetrically distributed with spool 2.An end that is positioned at valve seat 3 bottoms at through hole 9 offers intake chamber 10, and described intake chamber 10 communicates with through hole 9.The center line of described through hole 9 is set to acutangulate with the center line of spool 2, and from Fig. 1, a plurality of through holes 9 present the form that converges to valve plate 6 places.
Described in the utility modelly advance, in the discharge opeing valve block structure, described valve seat 3 bottoms are provided with seal ring 4, and sealing circle 4 is arranged at the periphery of intake chamber 10, promptly the diameter of sealing circle 4 is greater than the diameter of intake chamber 10 place circumference.
Described in the utility modelly advance, in the discharge opeing valve block structure, the bottom of described valve seat 3 also is provided with high-pressure seal ring 5, and this high-pressure seal ring 5 is arranged at the inner ring of intake chamber 10, promptly the diameter of this high-pressure seal ring 5 is less than the diameter of intake chamber 10 place circumference.
Described in the utility modelly advance, in the discharge opeing valve block structure, described valve plate 6 tops are provided with position limit socket 7, this position limit socket 7 is fixedlyed connected with spool 2.Further, be provided with the snap ring 1 of fixing this position limit socket 7 between described spool 2 and the position limit socket 7.Further be provided with limit spring 8 between the top of described position limit socket 7 and valve plate 6.
Briefly introduce below described in the utility modelly to advance, the working procedure of liquid discharging valve group:
Two faces of the upper and lower of valve seat 3 are respectively into, the discharge opeing sealing surface, adopt two kinds of different seal form respectively, for example: adopt the plane sealing seal form different with conical surface seal, this measure can effectively reduce the strike intensity of 2 pairs of valve seats 3 of discharge opeing spool, advance, the open and close of liquid discharging valve be both separate, interrelated again.
The negative pressure that the plunger of described plunger pump forms when extracting out drives feed liquor valve plate 6 and opens, suck pumped medium, pressure spring 8 can be to additional force of discharge opeing spool (liquid discharging valve also is subjected to suction function) simultaneously, and the closing velocity of liquid discharging valve will be realized water absorption course faster than feed liquor valve plate 6 opening speeds; Otherwise, when the plunger of plunger pump was pushed ahead, pressurized water can promote the discharge opeing spool and open, and pressure spring 8 can be to 6 one additional forces of feed liquor valve plate (the feed liquor valve is the effect of liquid body head also) simultaneously, the closing velocity of feed liquor valve plate 6 will be realized drainage procedure faster than the opening speed of liquid discharging valve.This process reciprocation cycle has just realized the proper functioning of plunger pump.
Described in the utility modelly advance, the discharge opeing valve block structure, by with feed liquor, discharge opeing function synthesized in one, reduced easily damaged parts quantity, reduce probability of malfunction, and make it to realize that the valve group is external, greatly reduce matching requirements, the maintenance of being more convenient for; Simultaneously, advance, liquid discharging valve interlock, also strengthened the intensity of valve group greatly, can effectively avoid pump head because of bearing the phenomenon that alternating stress ftractures; Moreover valve group and the coaxial setting of plunger reduce the change of liquid flow direction, and the space is compacter, has improved volumetric efficiency.
