Abstract
The utility model discloses an improved bottom valve for a pumping apparatus, which is provided with an annular ring on a valve bottom; the annular ring is provided with a spherical ball which is used as the valve of the sphere, and the internal side of the valve body on the upper part of the valve of the sphere is provided with a limited bolt. Because of the improvement to the valve, the water sealing effect of the improved bottom valve for a pumping apparatus is very good. The improved bottom valve for a pumping apparatus has the advantages of simple structure, convenient manufacture, and low cost.
Description
The utility model relates to a kind of bottom valve of water plug, especially the bottom valve of small-power water plug and Water pump.
Now the employed bottom valve valve mechanism of small-power water plug of Shi Yonging and the artificial Water pump of piston type is complicated, and its manufacture technology is also difficult, and using effect is not good enough, and cost is higher.
The purpose of this utility model provides a kind of simple in structure, and manufacture technology is also easier low-cost, a kind of water plug bottom valve that water sealing effect is very good.
In order to finish above-mentioned task, the scheme that the utility model is taked is: the valve body at the bottom of the valve is embedded in an annular ring, the Nei Yuan space of annular ring becomes an intake tunnel with the water inlet at the bottom of the valve, place the heavy spheroid valve of a proportion on the annular ring, a limited bolt that is fixed on the valve body is arranged in the valve body above the spheroid valve than water.Owing to the pressure difference inside and outside the valve body, water at the bottom of entering valve by valve bonnet backs down the spheroid valve when drawing water, and flows to the suction sleeve that links water plug then, because the effect of limited bolt, making the spheroid valve can not enter water plug influences pumping function.When stopping pumping, because spheroid valve own wt adds the pressure of water in the water inlet, the spheroid valve falls in the annular ring water inlet is sealed.
Because the spheroid valve of such scheme adopts the garden ball, its preparation process and structure are all very simple, and water sealing effect is very good.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Accompanying drawing is a vertical profile schematic representation of the present utility model.
In the vertical profile schematic representation of a kind of water plug bottom valve shown in the drawings, embed an annular ring (3) at the bottom of the valve in valve body (1) above (2), the interior space of circles of annular ring (3) becomes one to go into water channel with the water inlet of (2) at the bottom of the valve.Annular ring (3) is made best with the good material of elastic performances such as rubber, plastics.Annular ring (3) go up to place a proportion than the heavy garden ball of water as spheroid valve (4), valve body (1) in spheroid valve (4) top is upward made a call to two symmetrical holes, install wire, row culture is limited bolt (5), but also on each a bolt enter in the suction sleeve (6) in order to restriction spheroid valve (4).When water plug drew water, because pressure and external pressure in the valve body (1) are poor, water backed down spheroid valve (4) after by the filtration of valve bonnet (7) and flows into suction sleeve (6).Owing to stopping of limited bolt (5), spheroid valve (4) can not be entered in suction sleeve (6) and the water plug.When the operation of drawing water stops, because the change of the pressure in valve body gravity spheroid valve big and spheroid valve (4) self falls and is pressed on the annular ring (3), and annular ring (3) mouthful sealed, again because annular ring (3) has certain toughness, its good sealing effect and do not cause water leakage valve body (1) in.
Claims (2)
1, a kind of water plug bottom valve, by the suction sleeve (6), the valve body (1) that link water plug, bring (2) and valve bonnet (7) formation at the bottom of the valve at the mouth of a river into, it is characterized in that: have an annular ring (3) to be embedded in the valve body (1) at the bottom of the valve above (2), the Nei Yuan space of annular ring (3) is relative with the water intake of (2) at the bottom of the valve, the heavy spheroid valve (4) of one proportion than water arranged on the annular ring (3), there is a limited bolt (5) that is fixed on the valve body (1) top in spheroid valve (4) in the valve body (1).
2, by the described a kind of water plug bottom valve of claim 1, it is characterized in that: annular ring (3) can use elastic materials such as rubber, plastics to make.
