Technical Field
[0001] The utility model relates to the technical field of valves, in particular to a valve with a switch state indicating structure. Background Art
[0002] A valve is a device widely used in industrial systems to control the flow of fluids, such as air, water, steam, various corrosive media, mud, oil, and other types of fluids. A valve is a control component in a pipeline fluid delivery system, used to change the passage section and the flow direction of the medium, and has functions such as diversion, cutoff, throttling, non-return, diversion, or overflow pressure relief.
[0003] The control of the valve can adopt a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, gas-hydraulic, spur gear, bevel gear drive, etc., among which manual valves are the most common; manual valves are mainly driven by rotating the handwheel to drive the valve stem nut to rotate, so as to achieve the purpose of opening and closing the valve, connecting and cutting off the medium.
[0004] However, when the existing valve is in use, the valve does not have a structure that clearly indicates the switch state, which makes it difficult for the user to determine the switch state of the valve, that is, there is inconvenience for the user. Utility Model Content

That is, the utility model has the function of indicating the switch state of the valve, so that the user can easily judge the switch state of the valve, and thus can bring convenience to the user.
[0008] In a possible embodiment, a concave cavity is provided on the outer wall of the threaded ring, and a ball head is provided on one end of the swing rod, which is embedded in the concave cavity and movably connected to the concave cavity; by adopting this structure, when the threaded ring moves vertically relative to the threaded sleeve, the swing rod can be reliably driven to swing up and down under the cooperation of the ball head and the concave cavity, so that the pointer points to the character in the "on" state or the character in the "off" state; in addition, since the middle part of the swing rod is rotatably connected to the bracket through a pin shaft, the swing rod and the bracket are horizontally limited, and since the ball head is embedded in the concave cavity, the swing rod and the threaded ring can reliably achieve the purpose of circumferential limitation.
[0009] In a possible embodiment, an open groove is provided in the middle part of the bracket in the front-to-back direction, the swing rod is inserted into the open groove, the pin shaft is penetrated in the bracket and the swing rod, and an arc-shaped observation hole is provided at the end of the bracket away from the valve cover and passes through the bracket from front to back, the characters are located on one side of the observation hole, and the outer end of the pointer is arranged in front and back correspondence with the observation hole; by adopting this structure, both ends of the pin shaft can be connected to the bracket, and the middle part of the swing rod is rotatably connected to the pin shaft, so that the swing rod can be reliably rotatably connected to the bracket, and the rotation of the swing rod relative to the bracket is smoother. In addition, through the setting of the observation hole, the user can more easily observe the position of the pointer through the observation hole, so as to observe the characters indicated by the pointer and judge the switch state of the valve.
[0010] In a possible implementation, a plurality of circumferentially spaced milling planes are provided on the outer wall of the lower end of the threaded sleeve, and each milling plane vertically penetrates the external thread; by adopting this structure, while ensuring that the threaded ring and the external thread are threadedly connected, the contact area between the threaded ring and the external thread can be reduced, thereby avoiding jamming between the threaded sleeve and the threaded ring when the threaded sleeve rotates relative to the threaded ring to drive the threaded ring to move vertically.
