Preferably, the inboard of described valve pocket entrance is provided with the curved surface coordinated with valve ball.
Preferably, the body wall of valve pocket both sides is provided with the first perforate and second perforate of perforation, and an end of described limited post penetrates to the second perforate from the first perforate, two ends respectively with the first perforate of limited post, the second perforate interference fit.
Preferably, the end that limited post and the second perforate coordinate be provided with valve interior wall on be positioned at the step that the position of the second tapping coordinates.
Preferably, described valve body is nylon, plastics or metallic material.
Preferably, described valve ball is nylon, plastics or metallic material.
Preferably, described limited post is nylon, plastics or metallic material.
The utility model also provides a kind of one-way flow pipeline, comprises pipeline body, also comprises above-mentioned one-way valve, and whole one-way valve is positioned at pipeline body, the inwall interference fit of the outer wall of valve body and pipeline body in one-way valve.
Preferably, process chamfered in the termination of valve body in described one-way valve.
One-way valve of the present utility model, it is simple in structure, when current flow into from the entry end of valve pocket, i.e. P1 > during P2, current are for just flowing to; Otherwise P2 > during P1 current be adverse current to.When current when just flowing to, valve ball by the current top to the limited post laminating after, current can flow out from outlet; When current be adverse current to the time, the entrance laminating of valve ball and valve pocket, thus entrance is shut, current can not flow out from entrance.
One-way flow pipeline of the present utility model, whole one-way valve is positioned at pipeline, has avoided connecting one-way valve at pipe head, and compact structure not only, saved the installing space of one-way valve, optimized the connection of pipeline.
The accompanying drawing explanation
Fig. 1, Fig. 2 show the utility model one-way valve various flows to the time schematic diagram.
Fig. 3 shows the connection diagram of limited post and valve body.
Embodiment
For the technical problem that the utility model is solved, the technological scheme of employing, the technique effect easy to understand of obtaining, below in conjunction with concrete accompanying drawing, embodiment of the present utility model is described further.
With reference to figure 1, Fig. 2, the utility model provides a kind of one-way valve, comprise the valve body 1 that is provided with valve pocket 6, valve ball 2, limited post 3, one end of described valve pocket 6 is entrance 5, the other end is outlet 4, valve ball 2 is positioned at valve pocket 6, the internal diameter of valve pocket 6 is greater than the diameter of valve ball 2, valve ball 2 can be rolled along the length direction of valve pocket 6, described limited post 3 is fixed on outlet one side that is positioned at valve ball 2 in valve pocket 6, described valve ball 2 and limited post 3, the matching relationship of entrance 5 is as follows: when the pressure P 1 of entrance is greater than the pressure P 2 of outlet, described valve ball 2 has the circulation position towards outlet 4 is rolled and limited post 3 is kept out, when the pressure P 1 of entrance is less than the pressure P 2 in outlet port, described valve ball 2 has the closed position towards entrance 5 rolls also and entrances are sealed in entrance 5 laminatings.
When current flow into from entrance 5 ends of valve pocket 6, i.e. P1 > during P2, current are for just flowing to, with reference to figure 2, on the contrary P2 during P1 current be adverse current to, with reference to figure 1.When current when just flowing to, valve ball 2 by the current top to limited post 3 laminatings after, current can be from exporting 4 outflows; When current be adverse current to the time, entrance 5 laminatings of valve ball and valve pocket 6, current can not flow out from entrance 5.
In order to make valve ball 2 sealed entry 5 better, the inboard of described valve pocket entrance is provided with the curved surface 50 coordinated with valve ball 2.
The limited post 3 for stopping valve ball 6 arranged in valve pocket 6 can pass through Standard known in the art.The utility model preferably, with reference to figure 3, the body wall of valve pocket both sides is provided with the first perforate 11 and second perforate 10 of perforation, and an end of described limited post 3 penetrates to the second perforate 10 from the first perforate 11, and two ends respectively with the first perforate 11, second perforate 10 interference fit of limited post 3.More preferably, the end that limited post and the second perforate 10 coordinate be provided with valve interior wall on be positioned at the step 30 that the position of the second tapping coordinates.With reference to the view direction of figure 3, limited post 3 is lower end for the end with the second perforate 10 cooperations, and its external diameter is less than upper end, the wedgewise structure.
