Description

Technical Field

[0001] The utility model relates to the technical field of sealing valves, in particular to a sealing valve. Background Art

[0002] Valves are a common component of pipelines and are used as pipeline accessories to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium (temperature, pressure, and flow). Depending on their function, they can be divided into shut-off valves, check valves, regulating valves, or sealing valves.

[0003] The existing sealing valve is opened and closed by rotating a rotating mechanism, and is commonly operated by rotating a hand wheel, thereby driving the rotation of a valve control rod to open or close the sealing valve.

[0004] However, since the handwheel is generally connected to the valve control stem by bolts, it is easy to cause the handwheel to rotate in the event of accidental contact, thereby causing the valve to open or close abnormally. For this reason, a sealing valve is proposed. Utility Model Content

[0009] A limiting assembly, which is plugged into the interior of the sleeve assembly and is used to limit the position of the handlebar assembly;

[0010] A reset spring is provided in the middle of the limit assembly, and the reset spring is used to drive the limit assembly to reset.

[0011] Preferably, the limiting assembly includes a movable rod inserted into the middle of the fixed cover, a connecting round block fixedly connected to one end of the movable rod extending to the inside of the sleeve assembly, limiting blocks fixedly connected to both sides of the connecting round block, a fixed round block rotatably connected to one end of the movable rod extending to the outside of the sleeve assembly, a top block fixedly connected to both sides of the bottom of the fixed round block, grooves opened on both sides of the top of the fixed cover and limiting slots opened on both sides of the top of the handle assembly.

[0012] Preferably, the fixed cover includes a cover body threadedly connected to one end of the sleeve assembly and a plurality of protrusions fixedly connected to the outer side of the cover body, and the plurality of protrusions are distributed in a circular array.

[0013] Preferably, the sleeve assembly includes a fixed sleeve fixedly connected to the end surface of the fixed column and through slots opened on both sides of the fixed sleeve, and the position of each through slot corresponds to the position of the groove.

[0014] Preferably, the turning handle assembly includes a turning sleeve and a turning wheel fixedly connected to the outer side of the turning sleeve, and two limiting grooves are located on the top of the turning sleeve.

[0015] Preferably, the return spring is sleeved on the outer surface of the movable rod, and the return spring is located inside the rotating sleeve.

[0016] The technical effects and advantages of this utility model are:

[0017] Through the cooperation of the limit assembly and the return spring, the limit assembly limits the turning handle assembly, and then the turning handle assembly is rotated to drive the sleeve assembly and its fixed column to rotate, thereby driving the valve control rod to rotate, thereby realizing the opening or closing of the sealing valve body. When the turning handle assembly is not needed, the limit assembly no longer limits the turning handle assembly. At this time, even if the turning handle assembly is accidentally touched, the valve control rod will not rotate, nor will the sealing valve body be abnormally opened or closed. The fixing cover can be rotated and removed later to facilitate the assembly or disassembly of the turning handle assembly. BRIEF DESCRIPTION OF THE DRAWINGS
