Description

Technical Field

[0001] This utility model relates to the field of flow limiting valve technology, specifically a flow limiting valve base. Background Technology

[0002] A flow restrictor valve is an important device used to control fluid flow. It is widely used in hydraulic systems and industrial fields. As a safety protection valve, it is used for non-corrosive media such as oil. It closes immediately when the flow rate of the medium in the pipeline exceeds a set value. It also automatically closes when the pipeline or accessories are damaged and the flow rate is too high, preventing accidents from occurring or escalating. It is generally installed at the inlet and outlet of storage tanks or pipeline outlets to protect the safety and reliability of downstream equipment. The flow restrictor valve automatically controls the fluid flow by accurately comparing the spring preload with the medium flow rate, ensuring the safe and efficient operation of the system. It is widely used in key locations such as storage tank outlets and water pumps, and has the dual functions of flow restriction and silent check valve.

[0003] However, it still has some drawbacks. For example, when a flow restrictor base is in use, because the flow restrictor is installed on the top of the base, the flow passing through the flow restrictor will increase the weight of the flow restrictor and cause the flow restrictor to vibrate slightly. This process will aggravate the mutual friction between the flow restrictor and the base, causing wear on the outer shell of the flow restrictor and reducing its storage environment and safety.

[0004] To address the aforementioned issues, this application proposes a flow-limiting valve base. Utility Model Content

The rubber pad 10 is fixedly connected to the upper outer surface of the adhesive layer 9. Through the filling and adhesion of the rubber pad 10, wear on the metal shell of the equipment can be avoided, thus improving its storage safety.

[0022] In this embodiment, as Figure 1-2 As shown, a mounting plate 3 is fixedly connected to one outer surface of the groove base 1, and a fixed shaft 2 is threadedly connected to the inner wall of the mounting plate 3.
