[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0021] See also Figure 1-3 , the utility model provides a technical solution:

[0022] A valve visual stroke observation device includes an indicator 1, a drill hole is opened on one side of the indicator 1, a fixing block 5 is provided on the back of the indicator signal cap 2, the fixing block 5 is located inside the drill hole, an indicator signal rod is provided inside the indicator 1, the indicator signal rod includes an indicator signal rod body 3 and an indicator signal rod body 4, the rear end of the indicator signal rod body 3 is connected to the cylinder shaft, the other side of the indicator 1 is located at the cylinder shaft of the valve cylinder, the cylinder shaft is located inside the indicator 1, the indicator signal rod body 4 is provided at the front end center of the indicator signal rod body 3, a circular opening 9 is opened at the center of the indicator signal cap 2 and the fixing block 5, and the indicator signal rod body 4 is provided at the circular opening 9.

[0023] Furthermore, a thread 6 is provided on the surface of the fixing block 5 , and the fixing block 5 is connected to the drill hole via the thread, so that the indication signal cap 2 can be fixed to the indicating member 1 very conveniently, which is convenient for use.

[0024] Furthermore, an O-shaped sealing groove 8 is provided on the periphery of the back side of the indicator signal cap 2 , and an O-shaped sealing cap 7 is fixedly connected to the inside of the O-shaped sealing groove 8 to ensure the airtightness of the component to be sealed.

[0025] Furthermore, the material between the indication signal cap 2 and the fixing block 5 is high-impact grade organic glass.

[0026] Furthermore, the indicator 1 is made of high-impact organic glass.

[0027] Furthermore, the material between the indicator signal rod body 3 and the indicator signal rod body 4 is 2A12 aluminum alloy. 2A12 aluminum alloy is a high-strength duralumin that can be heat-treated and strengthened. 2A12 aluminum alloy has good spot weldability, but tends to form intergranular cracks when welded with gas welding and argon arc welding. 2A12 aluminum alloy has good machinability after cold work hardening. However, its corrosion resistance is not high, and anodizing, painting, or aluminum coating are often used to improve corrosion resistance.

[0028] Working principle: The utility model is a valve visual stroke observation device, in which an indicator 1 is provided at the cylinder shaft of the valve cylinder. The cylinder shaft is located in the indicator 1 and is connected to the indicator signal rod body 3. After the cylinder shaft moves, the indicator signal rod body 3 will also move, making the valve cylinder operation status visible, which is convenient for visual planning and management.

[0029] It should also be noted that during use, the indicator signal rod will flash at a regular frequency through the sensor element when the component moves. Since the indicator part 1 and the indicator signal cap are both made of organic glass, the flashing can be seen from the glass, which can be used to observe and determine whether the valve cylinder is running.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
