AI Technical Summary
Existing pneumatic diaphragm valves cannot visually display their open or closed status, which can easily lead to misoperation.
A mark, such as a red indicator ring, is placed on the outer end of the moving shaft of the pneumatic actuator to indicate the open or closed state through the movement of the piston.
It enables intuitive display of the status of pneumatic diaphragm valves, has a simple structure, does not require significant modifications to the original structure, and has promotional value.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to diaphragm pneumatic valve technical field, especially relate to a switch display actuating mechanism of pneumatic diaphragm valve. BACKGROUND
[0002] Diaphragm pneumatic valve is a kind of common cut-off valve, its general structure includes pneumatic actuating mechanism and valve body, and the closure or opening of diaphragm pneumatic valve is realized by the driving of pneumatic actuating mechanism, and pneumatic actuating mechanism generally includes shell, piston, spring, air passage, spring exerts force on piston, and piston drives the action of valve core in valve body to drive the action of diaphragm, to realize the closure or opening of diaphragm pneumatic valve;
[0003] Such pneumatic valve has a problem, that is, the closure or opening state of pneumatic valve cannot be directly observed, and the problem of misoperation can occur;
[0004] At present, there is no very suitable structure form to solve the above problems in prior art, and some pneumatic valves use marker float to realize state, which is relatively complex to realize, needs very large change to structure body itself, and is not suitable for state marking of such pneumatic valve. CONTENT OF UTILITY MODEL
[0005] The utility model provides a switch display actuating mechanism of pneumatic diaphragm valve, can solve the problem pointed out in background art.
[0006] A switch display actuating mechanism of pneumatic diaphragm valve, including pneumatic actuating mechanism body, the pneumatic actuating mechanism body includes shell, piston, spring and air passage, the piston is connected with the synchronous reciprocating motion of movable middle shaft, and the movable middle shaft is provided with the mark for marking the position of piston at the outside end.
[0007] Preferably, the mark is an indicating ring embedded in the outside end of the movable middle shaft.
[0008] Preferably, the indicating ring is a red indicating ring.
[0009] Beneficial effect: the utility model provides a switch display actuating mechanism of pneumatic diaphragm valve, increases the state marking of opening / closing, and the marking structure is very simple and intuitive, does not need to change greatly to original structure, is convenient to realize, has good popularization value and practical value. DRAWING DESCRIPTION
[0010] Figure 1 It is the structure schematic diagram of the utility model,
[0011] Mark explanation:
[0012] The figure label: shell 1, piston 2;Spring 3;Airway 4;Movable shaft 5;Mark 6. DETAILED DESCRIPTION
[0013] One specific embodiment of the present application will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of protection of the present application is not limited by the specific embodiment.
[0014] Example 1:
[0015] As Figure 1 shown, a switch display actuator of a pneumatic diaphragm valve, comprising a pneumatic actuator body, the pneumatic actuator body comprises a shell 1, a piston 2, a spring 3 and an airway 4, the piston 2 is connected with the movable shaft 5 which reciprocates synchronously, that is, the movable shaft 5 is arranged in the same direction with the piston 2 reciprocating direction, the shell 1 is provided with a shaft hole for the reciprocating movement of the movable shaft 5, the movable shaft 5 is provided with the airway 4, the compressed air is introduced into the cavity below the piston 2 through the airway 4, the spring 3 is located above the piston 2, providing a return force, the outer side end of the movable shaft 5 is provided with a mark 6 for marking the position of the piston, that is, the mark of the pneumatic valve is opened / closed;Specifically, the mark 6 is an indication ring embedded in the outer side end of the movable shaft 5, and the indication ring can be a red indication ring.
[0016] The present application only needs to open an embedded groove on the movable shaft 5, and the indication ring is embedded in the embedded groove, when the piston 2 moves, the indication ring will leak out / hidden into to mark the opening / closing of the pneumatic valve.
[0017] The above disclosure is only a few specific embodiments of the present application, but the present application is not limited to this, any person skilled in the art can think of the changes should fall within the scope of protection of the present application.
