Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a fully transparent resin-lined fluoropolymer bellows regulating valve. Background Technology

[0002] In the field of industrial fluid control, regulating valves, as core equipment for regulating fluid flow, pressure, and other parameters, are widely used in industries such as chemical, pharmaceutical, environmental protection, and water treatment. With the increasing demands for equipment safety, corrosion resistance, and control precision in industrial production, traditional regulating valves have gradually revealed numerous technical shortcomings, making it difficult to meet the needs of complex operating conditions. Traditional bellows regulating valves only have small observation windows embedded in local openings in the valve body, limiting the visible range and making it impossible to observe the state of the medium within the flow channel globally. Furthermore, the observation window relies on gaskets or adhesive seals to seal the metal valve body, and due to the different coefficients of thermal expansion, long-term exposure to thermal expansion and contraction and media corrosion can easily lead to seal aging, leakage, and observation window cracking.

[0003] Based on the above, this utility model proposes a fully transparent resin-lined fluoropolymer bellows regulating valve, which can effectively solve the above problems. Utility Model Content

However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0017] A fully transparent resin-lined fluoropolymer bellows regulating valve includes a valve body 1; one end of the valve body 1 has an inlet channel 101, and the other end of the valve body 1 away from the inlet channel 101 has an outlet channel 102; a valve stem cavity 103 is connected between the inlet channel 101 and the outlet channel, and a through hole 104 is connected between the inlet channel 101 and the valve stem cavity 103; a valve stem assembly is disposed in the valve stem cavity 103; a valve cover 2 is fixedly connected to the top of the valve body 1, and a clamp 3 is connected to the top of the valve cover 2; the valve body 1, the valve cover 2, and the clamp 3 are all made of transparent resin material.

[0018] The valve body 1, valve cover 2, and clamp 3 of this utility model are all made of transparent resin material, which makes the valve body 1, valve cover 2, and clamp 3 have visual characteristics, allowing for direct observation of the internal fluid flow status and the working status of the valve stem assembly. This facilitates real-time monitoring of equipment operation status and reduces the difficulty of troubleshooting. At the same time, the resin material itself has good corrosion resistance and chemical resistance, which can adapt to working conditions containing corrosive media and extend the overall service life of the valve body.

[0019] Furthermore, in another embodiment, the top of the valve cover 2 is connected to a pneumatic actuator 6 via a bracket 5.

[0020] By driving the pneumatic actuator 6 with accessories such as positioners and filters, the valve stem assembly can be automatically driven, improving the convenience of flow regulation.

[0021] Furthermore, in another embodiment, the valve stem assembly includes a valve stem 7, a bellows 8 is sleeved on the outer side of the valve stem 7, a valve core 9 is fixedly connected to the bottom end of the valve stem 7 and is connected to the through hole 104, and the top end of the valve stem 7 passes through the valve cover 2 and the bracket 5 and is connected to the pneumatic actuator 6.

[0022] By setting up a valve stem assembly, the bellows 8 is sleeved on the outside of the valve stem 7 and can extend and retract synchronously with the up and down movement of the valve stem 7, forming a dynamic sealing barrier during the movement of the valve stem, reducing the risk of fluid leakage from the gap between the valve stem and the valve body; and the matching structure between the valve core 9 and the through hole 104 ensures that the valve core 9 can adjust the fluid flow area by blocking or opening the through hole 104, thereby achieving effective control of the fluid flow between the inlet channel 101 and the outlet channel 102.

[0023] Furthermore, in another embodiment, the upper end of the bellows 8 is fixedly sealed to the valve cover 2, and the lower end of the bellows 8 is fixedly sealed to the valve core 9.

[0025] Through the coordinated action of spacer 10, spacer 11, packing assembly 12, packing sleeve 13 and packing plate 14, the static sealing performance between valve stem 7 and valve cover 3 is enhanced, and the risk of leakage is greatly reduced. At the same time, the packing plate 14 is made of transparent resin material, so the condition of packing assembly 12 can be directly observed from the outside, such as the degree of wear and whether there is any medium leakage.

[0026] Furthermore, in another embodiment, the valve core 9 is made of metal, and the outer surface of the valve core 9 is provided with fluoroplastic 15.

[0027] By providing a fluoropolymer lining on the outer surface of the valve core 9, the fluoropolymer lining has excellent corrosion resistance, high and low temperature resistance and non-stick properties, which can resist the erosion of the valve core by corrosive media.
