Abstract
The utility model relates to a novel one-way valve, comprising a main body of the one-way valve and a rubber ball which is arranged in the main body of the one-way valve, a strip-shaped guiding rod is arranged at the tail part of the rubber ball, and the parting lines of the strip-shaped guiding rod and the rubber ball are not vertical. Owning to the existence of the strip-shaped guiding rod, and the parting lines of the strip-shaped guiding rod and the rubber ball are not vertical, the parting line of the rubber ball cannot be in contact with an air vent hole due to the guiding limit function of the strip-shaped guiding rod when the novel one-way valve is used, the sealing performance of the valve is not affected even burrs exist, and the structural stability of the one-way valve is ensured.
Description
Technical field
The utility model relates to a kind of one-way valve, relates to a kind of valving.
Background technique
One-way valve is widely used in the various occasions with its characteristic, and its structure is in the one-way valve main body that in, has the step type hollow cavity ball being set, and when both sides pressure was different, ball is closed or unlatching hollow cavity passage through action of pressure; Because there is paring line in ball, the paring line place is easy to generate burr, and when the burr place contacted with the hollow cavity passage, there was the gap between the two in the existence at Yin Maoci place, is easy to generate gas leakage, and sealability is bad, and the stability of one-way valve is affected.
The model utility content
The utility model is to above-mentioned defective, and purpose is to provide a kind of good seal performance, one-way valve simple in structure, and this one-way valve stability is good.
The technological scheme of the utility model employing is for this reason: the utility model comprises an one-way valve main body and the ball that is arranged in the one-way valve main body, and the ball afterbody is established a strip guide rod, and the paring line out of plumb of strip guide rod and ball is provided with.
The utility model has the advantages that: the utility model is because the existence of strip guide rod; And it is provided with the paring line out of plumb of ball; During use because the guiding restriction of strip guide rod; The ball paring line can not contact with vent all the time, even make the existence of burr can not influence the sealability of valve, has guaranteed the stability of one-way valve structures yet.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is that one-way valve main body, 2 is that strip guide rod, 3 is ball among the figure.
Embodiment
The utility model comprises an one-way valve main body 1 and the ball 3 that is arranged in the one-way valve main body 1, and ball 3 afterbodys are established a strip guide rod 2, and the paring line out of plumb of strip guide rod 2 and ball 3 is provided with.
The working procedure of the utility model is: when there was pressure difference in one-way valve main body 1 both sides, ball 3 with the vent closure or openness, realized the work purpose of one-way valve under action of pressure; Because the existence of strip guide rod 2 makes the paring line of ball 3 not contact with the position of vent all the time, reach one-way valve excellent sealing performance and working stability performance simultaneously.
