Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically to a novel corrosion-resistant thin-film ball valve. Background Technology

[0002] Currently, the thin-body ball valve is a type of ball valve. Compared to ordinary ball valves, it has the advantage of a shorter valve body length. To facilitate the rotation of the valve stem, the handle is usually made longer. However, the handle's length exceeds the valve body, increasing the overall length of the thin-body ball valve. This prevents the space-saving advantage of the thin-body ball valve from being fully utilized, making it inconvenient for transportation. Furthermore, the connection between the valve stem and the valve cover is directly exposed, making a 100% static seal impossible. This tiny gap provides a channel for corrosive media (such as humid air, chemical mist, salt, etc.) to intrude, easily leading to corrosion and affecting its service life. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a new type of corrosion-resistant thin ball valve, which can seal the valve stem through the panel and the hand-held sealing plate, so as to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a novel corrosion-resistant thin ball valve, including a ball valve body, a panel is installed on the valve stem of the ball valve body, and hand-held sealing plates are installed at both ends of the panel through multiple hinges. The hand-held sealing plates are all wrapped around the outer ring of the connecting flange on the ball valve body and are set outside the connecting flange. The valve stem is sealed between the two connecting flanges through the panel and the hand-held sealing plates.

[0005] As a preferred technical solution, both sides of the panel and the handheld sealing plate extend to the outer ring surface of the connecting flange and are equipped with rubber strips, with the inner side of the rubber strips abutting against the outer ring surface of the connecting flange.

[0006] As a preferred technical solution, rubber sheets are installed at the joint between the panel and the handheld sealing plate, and the gap between the panel and the sealing handheld plate is sealed by the rubber sheets.

[0007] As a preferred technical solution, all hinge components are torsion spring hinges.

[0008] As a preferred technical solution, both the panel and the sealing handpiece are made of stainless steel.

[0009] As a preferred technical solution, the handheld sealing plates are all designed with a "C" shape, and one end of each handheld sealing plate forms a parallel part, which contacts the plane on the connecting flange.

[0010] As a preferred technical solution, the end of the hand-held sealing plate away from the panel is fitted together with the other end.

[0011] The beneficial effects of this utility model are: This utility model has a simple structure. Through a clever openable and closable structure, it serves as a protective structure under normal conditions, effectively isolating corrosion and solving the problem of easy corrosion of the valve stem; during operation, it serves as a temporary handle, solving the contradiction between the inconvenience of operation and space occupation of thin ball valves. This design significantly improves its corrosion resistance and space utilization while ensuring the core function of the valve, and facilitates transportation, installation and maintenance.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a novel corrosion-resistant thin ball valve, comprising a ball valve body 1. A panel 2 is mounted on the valve stem 7 of the ball valve body 1. Both ends of the panel 2 are equipped with hand-held sealing plates 3 via multiple hinges 6. The hand-held sealing plates 3 are all arranged around the outer ring of the connecting flange on the ball valve body 1 and are disposed outside the connecting flange. The valve stem 7 is sealed between the two connecting flanges through the panel 2 and the hand-held sealing plates 3.

[0022] In this embodiment, both sides of the panel 2 and the handheld sealing plate 3 extend to the outer ring surface of the connecting flange and are equipped with rubber strips 4. The inner side of the rubber strips 4 is in contact with the outer ring surface of the connecting flange.

[0023] In this embodiment, rubber sheets 5 are installed at the joint between the panel 2 and the handheld sealing plate 3, and the gap between the panel 2 and the sealing handheld plate is sealed by the rubber sheets 5.

[0024] In this embodiment, the hinge 6 are all torsion spring hinges, which can automatically close and seal the hand-held sealing plate by torsion of the torsion spring hinges.

[0025] In this embodiment, both panel 2 and the sealing hand plate are made of stainless steel to prevent rusting, while also having load-bearing capacity and the ability to rotate the valve stem.

[0026] In this embodiment, the handheld sealing plates 3 are all arranged in a "C" shape, and one end of each handheld sealing plate 3 forms a parallel part, which is in contact with the plane on the connecting flange.

[0027] In this embodiment, the end of the handheld sealing plate 3 away from the panel 2 is fitted together so that it can fully wrap around the outside of the connecting flange. A rubber layer can be installed on the end of the handheld sealing plate away from the panel to further ensure its sealing performance.

[0028] The working process is mainly divided into two states: closed and sealed state and open operation state.

[0029] In the closed, sealed state (normal, for protection), the stainless steel panel is directly fixed to the valve stem. The hand-held sealing plates at both ends naturally close inward under the elastic force of the torsion spring hinges (hinges), tightly wrapping around the connecting flanges at both ends of the ball valve. The panel, the two hand-held sealing plates, and the valve body of the ball valve together form a nearly fully enclosed cavity, completely protecting the most critical and easily corroded parts such as the valve stem root and the fit clearance between the valve stem and the valve cover.

[0030] The rubber strips installed on the inner side of the panel and the hand-held sealing plate are tightly attached to the outer ring surface of the connecting flange, effectively preventing external corrosive gases or liquids from radial intrusion; the gap between the panel and the hand-held sealing plate is covered by a rubber sheet to prevent the medium from seeping in from these joints; the hand-held sealing plate is designed in a "C" shape, and its parallel part at the end fits tightly with the plane of the connecting flange, further enhancing the sealing effect.

[0031] In the activation state (instantaneous, used to open and close the valve), the operator uses both hands or one hand to pull the two hand-held sealing plates outward and upward. Since the hinge is a torsion spring hinge, it is necessary to overcome its torque when pulling. The two hand-held sealing plates, together with the panel, form an operating handle that is easy to hold with both hands. This temporary handle provides a sufficiently long lever arm, making it easy and effortless to turn the valve stem.

[0032] The operator rotates the valve stem using this temporary handle, causing the ball core inside the valve body to rotate, thus controlling the on / off state of the pipeline. After operation, the operator releases the hand-held sealing plate. Under the restoring torque of the torsion spring hinge, the two hand-held sealing plates will automatically rotate inward, tightly wrapping around the connecting flange again, restoring the closed and sealed state.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
