Description
Technical field
The utility model relates to a kind of water pump member, relates in particular to a kind of telescopic bottom valve of water pump.
Background technique
Water pump is widely used in drawing water in the rural area, the conveying of irrigation and industrial liquid.Bottom valve is the critical component on the water pump, and the structure of bottom valve is made of upper valve body, following valve body and spool usually, and upper and lower valve body links into an integrated entity, and in the valve body spool is being installed down, and spool plays the interior valve port of valve body under the shutoff.Traditional spool is divided into two types of butt strip formula and spring thread rod-types, and wherein butt strip formula spool is a rubber structure, is connected with following valve body by a point, and the centering poor performance takes place eccentricly easily, so water plugging effect is bad.Simultaneously, the easily aging distortion of butt strip formula spool, corrosion resistance are poor, do not ensure working life.In addition, adopt the bottom valve of butt strip formula spool when installing and using directivity must be arranged, operation is extremely inconvenient.Though spring thread rod-type spool centering and water plugging effect are better, complex structure, the assembling difficulty, the cost of production height, the user is difficult to accept; Spring and screw mandrel are metalwork, and corrosion takes place easily, can influence the flexibility and the working life of valve core movement.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of flexibility and reliability, bottom valve of water pump that water plugging effect is good.
The technical solution of the utility model is as follows: a kind of telescopic bottom valve of water pump, comprise upper valve body, following valve body and spool, upper and lower valve body links into an integrated entity, spool is installed in down in the valve pocket of valve body, this spool is used for the valve port in the valve body under the shutoff, and its key is: described spool is made up of seal ring and stopper, and described seal ring is fitted in down in the valve body, the sealing circle is positioned at valve port top, sealing circle and this valve port central lines; Described stopper is a funnel shape, and described stopper inserts in the seal ring center hole and matches with seal ring.
Seal ring is fitted in down in the valve body and can transfer up and down, and seal ring has certain elasticity, and stopper is a funnel shape.Stopper insertion seal ring was blocked the seal ring center hole when water was downward, promptly valve port was blocked.When water pump began to draw water, the water pressure pushing stopper of the utility model seal ring bottom moved upward, and the seal ring center hole is opened, and was about to valve port and opened.
Above-mentioned stopper center upper portion is connected with guide rod, be horizontally arranged with guiding piece in the described upper valve body, the upper and lower end face of this guiding piece is spacing by the upper-end surface of the step surface in the upper valve body and following valve body respectively, and described guide rod passes the pilot hole that the guiding piece correspondence opened and matches with it.Stopper moves up and down can be eccentric, opens valve port like this or block valve port deviation can not occur, reliable more, water plugging effect is better.
Ring and outer shroud in above-mentioned guiding piece comprises, described in ring link together by uniform three ribs and outer shroud on its excircle.
Guide rod is located in the guiding piece and plays leading role in the ring, and guiding piece can block water not flow in valve body yet simultaneously.
Be evenly equipped with three limiting stoppers on the excircle of above-mentioned stopper top, this limiting stopper is pressed in the end face of described seal ring.
To stopper carry out spacing can be owing to the too complete works of clan of hydraulic pressure is gone in the seal ring.
Above-mentioned valve body excircle down is provided with and the corresponding boss circle in the lower end surface of upper valve body annular, the lower end surface of described upper valve body annular is the inclined-plane that inner ring is higher than the outer ring, described boss circle upper-end surface is the inclined-plane that the outer ring is higher than inner ring, is with packing ring on the following valve body between the lower end surface of described upper valve body annular and the boss circle upper-end surface.The waterproofing effect of valve body is better.
Be the cambered surface of middle part indent, the ellipse of described packing ring cross section as the inclined-plane between optimal design above-mentioned upper valve body lower end surface and boss circle upper-end surface inner ring and the outer ring for adapting with upper valve body lower end surface and boss circle upper-end surface.
Above-mentioned seal ring upper-end surface has circular groove, has a coil spring in this circular groove.Seal ring elasticity is better, and center hole is stretched and dwindles freely, and is better with the stopper fitted seal, and longer service life.
Beneficial effect: the utlity model has simple in structure, assembling is easy, corrosion-resistant, in light weight, cost is low, characteristics such as widely applicable, spool discharge water dirt, stick, the centering performance is good, the motion flexibility and reliability can play good water plugging effect.
