Description

Technical Field

[0001] This utility model relates to the field of clamp valve technology, specifically a manual rising stem clamp valve. Background Technology

[0002] Pinch valves, also known domestically as pipe clamp valves, airbag valves, or shut-off valves, have a sleeve that is the most crucial component. The sleeve is the core of any pinch valve, providing corrosion resistance, wear resistance, and pressure resistance. The quality of a pinch valve depends on the quality of its sleeve. The sleeve is squeezed using pneumatic, electric, manual, or hydraulic actuation to achieve the switching / regulating function. The rubber sleeve of the pinch valve, as a core component, typically consists of an inner layer, an outer layer, and reinforcing fibers.

[0003] However, existing manual rising stem clamp valves have the following problems during use: traditional clamp valves require a lot of labor to close, which is time-consuming and laborious, and do not provide a convenient and quick solution. Utility Model Content

[0004] The purpose of this invention is to provide a manual rising stem clamp valve to solve the related problems mentioned in the background art.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a manual rising stem clamp valve, comprising a valve body, a housing, and a rotating shaft. The housing is installed on the top of the valve body, and the rotating shaft is installed inside the housing via a bearing. A rotating cylinder is installed at the bottom of the rotating shaft, and an arc-shaped slide rail is formed on the outer wall of the rotating cylinder. A sleeve is provided inside the valve body, and a slide rail is provided inside the valve body. A clamping frame is provided inside the slide rail. A connecting plate is installed at the top of the clamping frame, and a transmission roller adapted to the inside of the arc-shaped slide rail is installed on the outer wall of the connecting plate. The transmission roller slides up and down on the inner wall of the arc-shaped slide rail to form a sliding connection.

[0006] As a preferred embodiment of the manual rising stem clamp valve of this utility model, flanges are installed on both sides of the valve body.

[0007] As a preferred embodiment of the manual rising stem clamp valve of this utility model, a throttle handle is installed above the rotating shaft.

[0008] As a preferred embodiment of the manual rising stem clamp valve of this utility model, a positioning rod is inserted into the outer wall of the throttle, and the bottom end of the positioning rod penetrates the interior of the outer shell.

[0009] As a preferred embodiment of the manual rising stem clamp valve of this utility model, the sleeve is made of neoprene rubber.

[0010] The advantages of this manual rising stem clamp valve are as follows: 1. This utility model drives the rotating shaft to rotate by turning the handle, thereby driving the rotating cylinder to rotate. The rotating cylinder then slides up and down in the arc-shaped slide rail via the transmission roller, so that the connecting plate drives the clamping frame to clamp the sleeve in the slide rail. This structure facilitates the quick opening and closing of the sleeve. The structure is simple and easy to operate. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1, as Figure 1-3As shown, this utility model provides a technical solution: a manual rising stem clamp valve, including a valve body 1, a housing 2, and a rotating shaft 3. The housing 2 is installed on the top of the valve body 1, and the rotating shaft 3 is installed inside the housing 2 via bearings. A rotating cylinder 11 is installed at the bottom of the rotating shaft 3, and an arc-shaped slide rail 12 is formed on the outer wall of the rotating cylinder 11. A sleeve 10 is provided inside the valve body 1, and a clamping frame 7 is provided inside the slide rail 6. A connecting plate 8 is installed at the top of the clamping frame 7, and a transmission roller 9 adapted to the inside of the arc-shaped slide rail 12 is installed on the outer wall of the connecting plate 8. The transmission roller 9 slides up and down on the inner wall of the arc-shaped slide rail 12 to form a sliding connection. Flanges 5 are installed on both sides of the valve body 1, and a handle 4 is installed on the top of the rotating shaft 3. The sleeve 10 is made of neoprene rubber, and a positioning rod is inserted into the outer wall of the handle 4. The bottom end penetrates the interior of the outer casing 2. By turning the handle 4, the operator drives the rotating shaft 3 to rotate, which in turn drives the rotating cylinder 11 to rotate. The rotating cylinder 11 then slides up and down within the arc-shaped slide rail 12 via the transmission roller 9. This causes the connecting plate 8 to drive the clamping frame 7 to clamp the sleeve 10 within the slide rail 6. Since the two sets of transmission rollers 9 are in opposite heights, when one side of the connecting plate 8 drives the clamping frame 7 to move downward, the other side of the connecting plate 8 drives the clamping frame 7 to move upward. The two sets of clamping frames 7 press against the middle position, thus achieving a rapid closing effect. This structure facilitates the rapid opening and closing of the sleeve 10. The structure is simple and easy to operate. When it is necessary to fix the closed position, a plug can be inserted into the handle 4 and fixed to the outer casing 2, thereby fixing the rotation angle of the rotating shaft 3 and obtaining a fixed closed state.

[0015] Working principle: First, the operator turns the handle 4 to drive the rotating shaft 3 to rotate, which in turn drives the rotating cylinder 11 to rotate. The rotating cylinder 11 then slides up and down in the arc-shaped slide rail 12 via the transmission roller 9, causing the connecting plate 8 to drive the clamping frame 7 to clamp the sleeve 10 in the slide rail 6. Since the two sets of transmission rollers 9 are located in opposite heights, when one side of the connecting plate 8 drives the clamping frame 7 to move downward, the other side of the connecting plate 8 drives the clamping frame 7 to move upward. The two sets of clamping frames 7 squeeze towards the middle position, thus achieving a rapid closing effect. This structure facilitates the rapid opening and closing of the sleeve 10. The structure is simple and easy to operate. When it is necessary to fix the closed position, a plug can be inserted into the handle 4 and fixed to the outer shell 2, thereby fixing the rotation angle of the rotating shaft 3 and obtaining a fixed closed state.

[0016] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
