Abstract
Description
Technical Field
[0001] This invention relates to a valve core control structure with micro-nano porous elastic material, belonging to the field of valve technology. Background Technology
[0002] Some high-precision flow control valves require a pilot valve structure to control the flow rate at the moment of valve opening and closing, thereby improving valve stability. However, most high-precision flow control valves are miniature structures, which makes the installation of the pilot valve structure more difficult, resulting in complex assembly, poor precision, inconvenient maintenance, and high operating costs. Summary of the Invention
[0003] To address the aforementioned technical problems, the objective of this invention is to propose a valve core control structure incorporating micro / nano porous elastic materials.
[0004] The technical solution of the present invention is implemented as follows: a valve core control structure with micro-nano porous elastic material, comprising a valve seat, a valve core and micro-nano porous elastic material; the valve seat has a flow channel hole structure, the valve core cooperates with the flow channel hole structure of the valve seat, and the micro-nano porous elastic material is disposed on the valve core or at the flow channel hole structure of the valve seat.
[0005] Preferably, the valve core is a plunger structure, the lower end of the valve core is matched with the flow channel hole structure of the valve seat, and micro-nano porous elastic material is fixedly disposed at the lower end of the valve core.
[0006] Preferably, the micro / nano porous elastic material is a gasket structure.
[0007] Preferably, the micro-nano porous elastic material is a hollow gasket structure, and the micro-nano porous elastic material is fixedly disposed on the flow channel hole structure of the valve seat, while the valve core floats and presses against the micro-nano porous elastic material.
[0008] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:
[0009] The valve core control structure of the present invention incorporates micro-nano porous elastic material. This material is placed at the mating point between the valve core and the valve seat. Because the micro-nano porous elastic material is airtight when compressed and permeable when uncompressed, it can act as a valve pilot, replacing the existing pilot valve structure. This achieves the effects of reducing starting voltage, reducing power consumption, and improving valve stability. The overall structure is simple, easy to install, and significantly reduces maintenance and usage costs. Attached Figure Description
[0010] The technical solution of the present invention will be further described below with reference to the accompanying drawings:
[0011] Appendix Figure 1This is a schematic diagram of one embodiment of the valve core control structure with micro-nano porous elastic material described in this invention;
[0012] Appendix Figure 2 This is a schematic diagram of another embodiment of the valve core control structure with micro-nano porous elastic material described in this invention. Detailed Implementation
[0013] The present invention will now be described with reference to the accompanying drawings.
[0014] As attached Figure 1-2 As shown, the valve core control structure with micro-nano porous elastic material of the present invention includes a valve seat 1, a valve core 2 and micro-nano porous elastic material 3; the valve seat 1 has a flow channel hole structure, the valve core 2 cooperates with the flow channel hole structure of the valve seat 1, and the micro-nano porous elastic material 3 is disposed on the valve core 2 or at the flow channel hole structure of the valve seat 1.
[0015] The micro-nano porous elastic material 3 is airtight when compressed, but permeable when not compressed.
[0016] As one implementation method, as shown in the appendix Figure 1 As shown, the valve core 2 is a plunger structure, and the lower end of the valve core 2 is matched with the flow channel hole structure of the valve seat 1. The micro-nano porous elastic material 3 is a gasket structure, and the micro-nano porous elastic material 3 is fixedly installed at the lower end of the valve core 2.
[0017] When the valve core 2 moves downward and engages with the valve seat 1, it gradually compresses the micro-nano porous elastic material 3, causing it to gradually seal until it is completely sealed. When the valve core 2 moves upward and disengages from the valve seat 1, it causes the micro-nano porous elastic material 3 to gradually disengage from the compressed state, resulting in a linear change in flow rate.
[0018] As another implementation method, see attached Figure 2 As shown, the micro-nano porous elastic material 3 is a hollow gasket structure. The micro-nano porous elastic material 3 is fixedly disposed on the flow channel hole structure of the valve seat 1. The hollow structure of the micro-nano porous elastic material 3 matches the flow channel hole of the valve seat 1. The valve core 2 floats and presses onto the micro-nano porous elastic material 3.
[0019] When the valve core 2 moves downward, it gradually compresses the micro-nano porous elastic material 3, gradually sealing it until it is completely sealed; when the valve core 2 moves upward, it causes the micro-nano porous elastic material 3 to gradually break free from the compressed state, causing the flow rate to change linearly.
[0020] For valves with pilot valves, the technology in this solution can eliminate the pilot valve, making the valve structure simpler.
[0021] For valves that did not originally have a pilot valve, the technology in this solution can reduce startup power consumption and improve valve startup stability.
[0022] The technology in this solution can be used in fluid environments such as gases or liquids.
[0023] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
