Abstract
The utility model discloses a tapered column type guiding ball valve for a pump, including a valve seat and a valve ball mounted therein; a valve cover is disposed on the upper part of the valve seat; a spring is disposed between the valve cover and the valve ball; at least three guiding columns are arranged on the valve seat; and the valve ball is installed in an internal space enclosed by the guiding columns. The tapered column type guiding ball valve for the pump overcomes various defects of large-area contact or no-contact, is simple in structure, reliable in sealing and stable in work and has the self-cleaning function.
Description
Technical field
The utility model relates to the pump valve technical field, especially a kind of pump taper pillar Guiding ball valve.
Background technique
At present, employed pump valve has mushroom valve (mostly being flap type, cone valve), annular valve, deadweight valve (mostly being ball valve) etc. on the displacement pump.Pump valve be in the displacement pump working procedure direct component parts, also be one of most important easily damaged parts in the displacement pump, the service behaviour that the quality of its design directly influence pump with benefit from the life-span.Yet in the process of practice: flap type is widely used in conveying than the low viscosity medium, and working pressure is not high, and sealing effect neither be too desirable; Cone valve is because complex-shaped, and to making having relatively high expectations of processing, this valve requires valve seat and spool not to exchange, and makes valve seat and spool lose interchangeability, the corresponding user cost that strengthened; Annular valve is as a kind of modification of flap type and mitre velve, because annular valve is twice than identical flap type interval area or manys times, and because of the big poor rigidity of valve plate diameter, seldom adopts in high-pressure service pump; The deadweight valve is not owing to there is spring, and the valve plate inertia force influence is bigger, and steering capability neither be fine, only is applicable to reciprocal time lower (change n＜120 usually), the pump that flow is little.
The model utility content
At the problem that prior art exists, the purpose of this utility model be to provide a kind of simple in structure, sealing is reliable, stable working, have a self-cleaning function pump with taper pillar Guiding ball valve.
For achieving the above object, the utility model pump taper pillar Guiding ball valve, comprise valve seat and the valve ball that is mounted in it, the top of valve seat is provided with valve bonnet, be provided with spring between valve bonnet and the valve ball, at least be provided with 3 directional posts on the valve seat, valve ball is installed within the inner space that each directional post surrounds.
Further, the cross section of described directional post is a cone structure, and the little end surface of this cone structure is the guide surface of described valve ball motion.
Further, the length of described directional post is to the spacing the sealing surface upper surface of described valve seat from described valve bonnet below.
Further, described directional post and valve seat integral structure.
Further, described directional post is along the circumferential even distribution of described valve seat.
Further, the bottom of described valve bonnet is provided with the assembly department of described spring, and described spring housing is contained on this assembly department.
Further, described valve bonnet and valve seat adopt and are threaded, and both joints are provided with O shape circle.
The utility model pump has overcome large size contact or discontiguous all disadvantages with taper pillar Guiding ball valve, have simple in structure, sealing is reliable, stable working, have advantage such as self-cleaning function.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 be among Fig. 1 A-A to sectional view.
Embodiment
As shown in Figure 1 and Figure 2, the utility model pump comprises valve seat 5, valve ball 4 with taper pillar Guiding ball valve, and valve ball 4 is contained in the valve seat 5.The top of valve seat 5 is adopted to be threaded and is provided with valve bonnet 2, and both joints are provided with O shape circle 1, and it is loosening that O shape circle 1 can avoid valve ball 4 to cause in the course of the work between valve bonnet 2 and the valve seat 5.
Be provided with spring 3 between valve bonnet 2 and the valve ball 4, the bottom of valve bonnet 2 is provided with the assembly department 7 of spring, spring 3 is sleeved on the assembly department 7, by on valve ball 4, adding shock mount 3, increased the load of valve ball 4, reduced inertial force, solved the influence of valve ball motion inertia force, guarantee less closing velocity and closed retardation angle, reduced to impact and reflux damage, prolonged the working life of pump valve.Spring 3 is enclosed within on the assembly department 7 of valve bonnet 2, makes spring 3 that fine guidance quality also be arranged, and has reduced the eccentric wear of spring 3.
The utility model pump taper pillar Guiding ball valve, adopted the design of valve seat and guide mechanism integrated type on the structure, avoided deflection when such pump valve guide mechanism effect is to make valve ball to close, well guaranteed sealability, made pump delivery more stable, more reliable simultaneously.The structure of valve seat and guide mechanism integrated type, avoided the split type combination decentraction of valve seat and guide mechanism, processing is got up simpler, the dismounting of being more convenient for, each corner angle of valve seat all adopt smooth excessive fillet, medium shearing to macromolecular chain is little, is fit to carry macromolecular chain and full-bodied medium, is applicable to the pump of large, medium and small working pressure and discharge capacity.
At least 3 directional posts 6 make valve ball move in the slideway of an annular.The integrated type of valve seat and guide mechanism, make the work approximate straight line motion of valve ball in slideway, in the process of work, can not produce deflection and cause close power inequality, motion steadily can not influence sealing effect, owing to be three or more directional post 6, make to be not easy in the work of valve ball " stuck " phenomenon to occur, bigger area of passage design on the structure makes the work of pump valve and entire pump more steady.
Valve ball 4 is the steel ball of standard or the ball of other materials in the utility model, and simple in structure, interchangeability is strong, the dismounting aspect, be convenient to clean.With rotatablely moving, wear and tear evenly, and the impurity that valve ball and sealing contact surface adhere to is eliminated ball valve easily, has " self-cleaning " function in opening and closing and moving.
Claims (7)
