Detailed Description
In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
In one embodiment, as shown in fig. 3-9, an atraumatic one-way valve comprises:
A first valve plate 1 provided with a first opening 4, wherein at least two first corbels 5 intersecting at a center point are arranged in the first opening 4;
the valve plate 2 is connected with the first valve plate 1, the position of the valve plate covering the first opening 4 is divided by dividing lines to form dividing areas, and each dividing line 6 is opposite to one first supporting beam 5;
The second valve plate 3 is located at the side of the first valve plate 1, connected with the first valve plate 1 and/or the valve plate 2, and is provided with a hollowed-out supporting part 7 which is used for supporting the partition area and does not interfere the partition area to move towards the partition area so as to be opened, and is opposite to the partition area.
It should be noted that the first valve plate 1 may be a common plate or a vibration plate. In the case where the first valve plate 1 is a vibration plate, a gap between a portion of the second valve plate 3 facing the vibration region of the first valve plate 1 and the vibration region of the first valve plate 1 is larger than an amplitude of the vibration region of the first valve plate 1 to avoid interference with the vibration of the first valve plate 1.
Specifically, the position of the second valve plate 3 facing the partition area is provided with the hollowed supporting part 7, so that the first supporting beam 5 and the hollowed supporting part 7 can both support and limit the valve plate 2 under the conditions that the valve plate 2 reciprocates and fluid can flow normally and unidirectionally, the valve plate 2 is prevented from being damaged due to oversized movement, and the reliability and the service life of the check valve are improved.
The hollow supporting portion 7 may have various structures, and three types of structures are listed:
First, the hollowed supporting portion 7 includes a second opening 71 formed on the second valve plate 3 and one supporting ring 72 or at least two coaxial supporting rings 72 arranged at intervals in the second opening 71, and the supporting rings 72 are connected with the components on the inner side and the outer side of the supporting rings so as to form a whole.
Second, as shown in fig. 3, the hollowed supporting portion 7 includes a second opening 71 formed in the second valve plate 3, at least one supporting ring 72 and at least two second supporting beams 73 intersecting with each other at a center point, wherein the at least one supporting ring 72 is disposed in the second opening 71, the supporting ring 72 is connected with the inner and outer parts of the supporting ring through the second supporting beams 73, and two surfaces of the second supporting beams 73 are respectively flush with the supporting ring 72.
As shown in fig. 4-8, the hollow supporting portion 7 includes a second opening 71 formed in the second valve plate 3, and at least two second supporting beams 73 disposed in the second opening 71 and intersecting with each other at a center point, where the second supporting beams 73 are offset from the first supporting beams 5 by a certain angle. The number of the first corbels 5 and the second corbels 73 may be two, three, four, or the like, as required. In general, the number of second corbels 73 is identical to the number of first corbels 5.
It should be noted that the structure of the hollowed-out supporting portion 7 is not limited to the above description, and may be other structures. The hollow supporting portion 7 may be formed by hollowing out a corresponding area of the second valve plate 3, or may be formed by directly forming a complete second opening 71 in the second valve plate 3, and then connecting a supporting ring 72 and/or a second supporting beam 73 in the second opening 71, which is not limited herein.
In order to make the hollow support portion 7 not interfere with the opening of the valve plate 2, various structures may be adopted, such as making the side of the hollow support portion 7 facing the valve plate 2 lower than the side of the second valve plate 3 facing the valve plate 2. For another example, as shown in fig. 7 and 8, a movement space for allowing the valve plate 2 to move back to the first valve plate 1 to be opened is reserved between the second valve plate 3 and the valve plate 2, and the movement space covers the hollowed supporting portion 7. In order to form a movement space without increasing the thickness of the check valve, as shown in fig. 3, 4, 7 and 8, a groove 9 may be formed in the second valve plate 3, and the space in the groove 9 may be used as the movement space.
In one embodiment, as shown in fig. 3, 4 and 7, the diameter of the recess 9 is larger than the diameter of the valve plate 2 to completely cover the valve plate 2. So set up, during the equipment, second valve plate 3 only with first valve plate 1 gluing or welding can, simplified manufacturing technique.
In one embodiment, as shown in fig. 3, 4 and 6, each parting line 6 extends beyond the respective first corbel 5 at both ends. So set up, valve block 2 moves under the fluidic effect towards the second valve plate 3 under the condition of opening, and the opening of valve block is big enough, guarantees that the fluid flows smoothly, also can increase velocity of flow and flow.
In one embodiment, as shown in fig. 3, 4 and 6, the parting line 6 averages the position of the valve plate 2 covering the first opening 4. In this way, with the valve plate 2 open, a uniform flow of fluid through the individual openings of the valve plate 2 can be ensured.
In one embodiment, as shown in fig. 9, the intersection position of the first corbel 5 is provided with a plurality of flow ports 8 staggered with respect to the dividing line 6. So configured, the flow rate and flow rate of the pump can be raised. In addition, in order to improve the aesthetic degree and reduce the influence of the flow openings 8 on the strength of the first corbel 5 as much as possible, all the flow openings 8 are arranged centripetally.
In one embodiment, a fluid pump includes the atraumatic one-way valve of the above embodiments.
With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
