Description

Technical Field

[0001] The utility model relates to the technical field of umbrella-shaped valves, in particular to a multi-layer rubber umbrella valve. Background Art

[0002] The multi-layer rubber umbrella valve is a valve mainly used to control the flow of fluid. It is mainly composed of a valve body, a valve disc and a drive device. The valve disc is made of rubber material and has good elasticity and sealing performance.

[0003] For example, the utility model with announcement number CN204284549U relates to the technical field of umbrella-shaped valves, specifically an umbrella-type one-way valve, including an umbrella-shaped body and a positioning column fixed thereunder, the bottom surface of the umbrella-shaped body is a sealing plane, the positioning column is perpendicular to the sealing plane, the positioning column is formed at the center of the sealing plane, and a limited position clamping plate is formed at the bottom of the positioning column. The utility model uses the lower plane of the flat umbrella-shaped body as a sealing surface to form a surface contact seal with the outlet structure. When the outlet area is the same, the flow area is large, the outflow is smoother and more uniform, and the height of the application structure can be effectively reduced.

[0004] In the process of implementing this application, it was found that the technology has the following problems: the umbrella-shaped valve is an integrally formed single-layer design. When in use, the single-layer umbrella-shaped valve not only has poor sealing, but also when the umbrella-shaped valve is damaged and needs to be repaired or replaced, the entire umbrella-shaped valve needs to be replaced, which wastes resources and increases maintenance costs.

[0005] A multi-layer rubber umbrella valve is proposed for this reason. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that the single-layer umbrella-shaped valve not only has poor sealing performance, but also needs to replace the entire umbrella-shaped valve when the umbrella-shaped valve is damaged for repair and replacement, which wastes resources and increases the maintenance cost. The utility model provides a multi-layer rubber umbrella valve.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] A multi-layer rubber umbrella valve comprises a positioning column, wherein the bottom array of the positioning column is provided with an umbrella valve assembly for controlling fluid flow, and the surface of the umbrella valve assembly is provided with a connecting assembly for assembling the umbrella valve assembly.

[0009] Furthermore, the umbrella valve assembly comprises an umbrella-shaped block, a docking hole is provided on the surface of the umbrella-shaped block, and the docking hole passes through the umbrella-shaped block.

[0010] By adopting the above technical solution, the function of the umbrella-shaped block is to fit with the flow channel of the fluid to achieve one-way flow of the fluid, while the function of the docking hole is to facilitate the subsequent assembly.

[0011] Furthermore, an anti-suction groove is provided on the top surface of the umbrella-shaped block, and reinforcing ribs are arranged in an array in the anti-suction groove.

[0012] By adopting the above technical solution, the diameter length of the anti-suction groove is smaller than the diameter length of the umbrella-shaped block. When the umbrella-shaped block fits with the flow channel, the anti-suction groove prevents the umbrella-shaped block from fitting tightly, and the reinforcing ribs in the anti-suction groove give the umbrella-shaped block a restoring force, thereby preventing the umbrella-shaped block from folding.

[0013] Furthermore, the connection assembly comprises a support block, a surface of the support block is provided with a docking groove, and the umbrella-shaped block is nested in the docking groove through a docking hole.

[0014] By adopting the above technical solution, the umbrella-shaped block can be tightly nested on the surface of the supporting block, which is convenient for disassembly and installation.

[0015] Furthermore, a connecting column is provided on the surface of the support block, and the connecting column passes through the support block, a threaded groove is provided at the top end of the connecting column, and a threaded column is provided at the bottom end of the connecting column.

[0016] By adopting the above technical solution, the two connecting components are fixedly connected via the threaded column and the threaded groove.

[0017] Furthermore, a limiting bead is provided on the surface of the positioning column, and the bottom end of the positioning column is threadedly connected to the thread groove, and the umbrella-shaped block is made of rubber thermoplastic.

[0018] By adopting the above technical solution, the connecting column and the limiting bead are used to facilitate the positioning and installation of the entire umbrella valve, and the umbrella-shaped block is made of rubber, which leads to good sealing performance of the umbrella valve.

[0019] The beneficial effects of the utility model are as follows:

[0020] The utility model provides a connecting component on the surface of the umbrella valve component, not only can the connecting component and the umbrella valve component be disassembled and assembled, but also the single-layer umbrella-shaped valve can be transformed into a multi-layer structure by splicing and installing the connecting components. This design not only improves the sealing performance of the umbrella valve, but also when the umbrella-shaped valve is damaged and needs to be repaired and replaced, only the damaged parts need to be replaced, thus saving resources and reducing repair costs.
