Abstract
The invention relates to a check valve which comprises a check valve main body and a rubber ball, wherein the rubber ball is arranged in the check valve main body, a strip-shaped guide bar is arranged at the tail part of the rubber ball, the strip-shaped guide bar and a parting line of the rubber ball are non-perpendicularly arranged. Due to existence of the strip-shaped guide bar, the strip-shaped guide bar and the parting line of the rubber ball are non-perpendicularly arranged, the parting line of the rubber ball can not be contacted with vent holes all the time due to guidance limiting role of the strip-shaped guide bar, the sealing property of the valve can not be influenced even under the existence of burrs, and the structure stability property of the check valve can be ensured.
Description
Technical field
The present invention relates to a kind of one-way valve, relate 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 has the step type hollow cavity in a ball being set, and when both sides pressure was different, ball is closed or unlatching hollow cavity passage by the effect of pressure difference; Because there is paring line in ball, the paring line place easily produces 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, easily produces gas leakage, and sealability is bad, and the stability of one-way valve is affected.
Summary of the invention
The present invention is directed to defects, 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 technical solution used in the present invention is for this reason: the present invention includes an one-way valve main body and be arranged on the interior ball of one-way valve main body, the ball afterbody is established a strip guide rod, and the paring line out of plumb of strip guide rod and ball arranges.
Advantage of the present invention is: the present invention is because the existence of strip guide rod, and the paring line out of plumb of itself and ball arranges, during use because the guiding restriction of strip guide rod, the ball paring line can not contact with vent all the time, even so that the existence of burr also can not affect the sealability of valve, guaranteed the stability of one-way valve structures.
Description of drawings
Fig. 1 is structural representation of the present invention.
1 is that one-way valve main body, 2 is that strip guide rod, 3 is ball among the figure.
Embodiment
The present invention includes an one-way valve main body 1 and the ball 3 that is arranged in the one-way valve main body 1, 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 arranges.
Working procedure of the present invention 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 the effect of pressure difference; Simultaneously because the existence of strip guide rod 2 so that the paring line of ball 3 does not contact with the position of vent all the time, reaches the good sealability of one-way valve and working stability performance.
