Abstract
Description
Technical Field:
[0001] The utility model relates to the technical field of fluid pulse rectification, and more specifically to a fluid pulse buffer film of a fluid pulse rectifier. Technical Background:
[0002] In the technical field of fluid pulse rectification, there are various forms of fluid pulse rectifiers, dampers, and buffers, which have the same functions and uses. The characteristics are that they are relatively large in volume, and most products do not use buffer film filtering technology, and the fluid output cannot effectively suppress pulses.
[0003] Chinese Patent Application No. CN20172172481.4 discloses a fluid pulse rectifier. The utility model provides a fluid pulse rectifier that can effectively control the amplitude of water flow pulses, but the structural characteristics of its pulse buffer film make its fatigue resistance not ideal, resulting in poor product life and stability.
[0004] At the same time, the existing fluid buffer films are difficult to implement in standardized assembly line production, resulting in a low yield rate. Summary of the Utility Model:
[0005] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a fluid pulse buffer film 1, which is characterized in that the fluid pulse buffer film 1 is an integral composed of a filtering layer 11, an O-ring positioning seal 12, and an arc angle 13. The O-ring positioning seal 12 is arranged on the outer edge of the filtering layer 11, and both the front and back sides of the connection between the O-ring positioning seal 12 and the filtering layer 11 are set as arc angles.
[0006] In a preferred technical solution, the elastic material is elastic rubber, including HTV silica gel, FKM fluororubber, FFKM perfluororubber, etc.
[0007] Further preferably, the above materials are HTV silica gel, FKM fluororubber, and FFKM perfluororubber.
[0008] In a preferred technical solution, the thickness of the filtering layer 11 is selected to be 0.3 - 1.98 mm.
[0009] In a preferred technical solution, the number of the O-ring positioning seals 12 is 1 - 3. When the number of the O-ring positioning seals 12 is two or more, the diameters of the O-ring positioning seals are gradually increased and arranged concentrically, and there is a gap between each O-ring positioning seal.
[0010] The fluid pulse buffer film provided by the utility model has the following beneficial effects.
[0011] 1. The innovation of the present utility model lies in that, by utilizing the relationship between the structure and specific thickness of the fluid pulse buffer film, and specific materials, an ideal fluid pulse buffer filtering effect is achieved. At the same time, the addition of special materials and the arc angle 13 stabilizes and improves the product life.
[0012] 2. The design of the unique structure of the fluid pulse buffer film enables the product to be easily realized in standardized assembly line production. The defective rate of the product is greatly reduced, effectively reducing the product cost and the labor intensity of workers, facilitating mass production, and bringing significant economic benefits.

[0021] As Figure 1 shown, the outer shape of the fluid pulse buffer film 1 in this embodiment is set to be circular, and the thinner part in the middle is the filtering layer 11, that is, the central area of the fluid pulse buffer film 1. However, in the embodiments under specific working conditions, the outer shape of the fluid pulse buffer film 1 can be set to be square.
[0022] As Figure 1 、 2 shown, the outer shape of the fluid pulse buffer membrane 1 is concave on both sides, and the relatively thin part in the middle is the filtering layer 11. An O-ring positioning seal ring 12 is provided at the circumference of the filtering layer 11. Both the front and back sides of the connection between the O-ring positioning seal ring 12 and the filtering layer 11 are arc angles.

When the thickness of the filtering layer 11 is set between 1.1 and 1.98 mm, the number of the O-ring positioning seal rings 12 should be set to two. When the fluid pressure is greater than 116 psi and the temperature is greater than 102 °C, the number of the O-ring positioning seal rings 12 should be set to three. When the number is two or more, the diameters of the O-ring positioning seal rings are increased one by one and arranged concentrically, and there is a gap between each O-ring positioning seal ring.
