Description
Technical field
The utility model relates to a kind of aperture indicating device of valve, especially a kind of non-rising stem valve family of power and influence's aperture indicating device.
Background technique
Valve can be divided into rising stem (RS.) valve and ono-rising-stem valve by the motion state demonstration of valve rod in the switching process; The rising stem (RS.) valve namely can be observed rising or the decline of valve rod in valve opening or the process of closing, the height that can rise from valve rod intuitively be judged the size of valve open; Another kind of ono-rising-stem valve namely can't be observed the motion state of valve rod in valve opening or the process of closing, therefore need to install the opening degree that an aperture indicating device reflects ono-rising-stem valve.General this aperture indicating device comprises gear-box, and gear-box is provided with pointer and indicator panel, be provided with driving gear and driven gear in the gear-box, driving gear is fixedlyed connected with valve rod, and driven gear is connected with pointer, and pointer a certain position of indication on indicator panel just represents the aperture of valve.Because in the process of valve from the standard-sized sheet to the full cut-off, valve rod will rotate a lot of circles, so pointer also can rotate thereupon; Yet the unique opening value for the last valve that guarantees any point representative on the indicator panel, so the process of valve from the standard-sized sheet to the full cut-off, pointer must rotate in a week, therefore the rotating speed of driving gear need pass through multi-stage speed-reducing, make the final stage driven gear of concatenation pointer in the process of valve from the standard-sized sheet to the full cut-off, the rotational angle of pointer is less than or equals a week.The valve opening indicating device of said structure need make driving gear just can reach in the process of valve from the standard-sized sheet to the full cut-off through multi-stage speed-reducing, and the rotational angle of pointer is less than or equals the purpose in a week, and its complex structure, volume are big.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, volume is little, do not need the aperture indicating device of the ono-rising-stem valve of reduction gear.
To achieve these goals, the technical solution adopted in the utility model is: a kind of aperture indicating device of ono-rising-stem valve, comprise gear-box, pointer and indicator panel, gear-box comprises casing and loam cake, be provided with intermeshing driving gear and driven gear in the casing, driving gear is fixedlyed connected with valve rod, be provided with gear shaft in the casing, driven gear is installed on the gear shaft, it is characterized in that: also be provided with the modified gear with the coaxial setting of described driven gear in the described casing, the number of teeth difference of the number of teeth of modified gear and described driven gear one or more; Modified gear and the engagement of described driving gear, described indicator panel is installed on the modified gear, and described pointer is installed in the end that described gear shaft stretches out described casing, and described casing and described loam cake are wholely set.
As further setting of the present utility model, described indicator panel is installed on the modified gear by rivet.
As further setting of the present utility model, described driving gear is installed on the described valve rod by flat key.
As further setting of the present utility model, be provided with the boss that supports described driving gear in the described casing, be provided with pad between boss and the described driving gear.
Adopt such scheme, the utility model reaches the displacement effect by the driven gear of coaxial setting is arranged to the different numbers of teeth with modified gear, driven gear is fixedlyed connected with gear shaft, the gear shaft end is provided with pointer, and indicator panel is arranged on the modified gear, because the number of teeth difference of these two gears, revolution moves a week, just produce differential seat angle between these two gears, constitute the displacement system of angle of swing; And can be by the design to the number of teeth of driven gear and modified gear, make any point on the pointed indicator panel all represent unique opening value of valve; Casing and the loam cake of gear-box are wholely set, and have made things convenient for manufacturing, and the pad between driving gear and the casing boss can play the effect that reduces to wear and tear.The utlity model has advantage simple in structure, that volume is little, easy to process.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Accompanying drawing 1 is the utility model specific embodiment structural representation;
Accompanying drawing 2 is the enlarged view of I in the accompanying drawing 1.
Embodiment
Specific embodiment of the utility model is the aperture indicating device of ono-rising-stem valve shown in Fig. 1-2, comprise gear-box 1, pointer 2 and indicator panel 3, gear-box 1 comprises casing 11 and loam cake 12, be provided with intermeshing driving gear 4 and driven gear 5 in the casing 11, driving gear 4 is fixedlyed connected with valve rod 7, be provided with gear shaft 8 in the casing 11, driven gear 5 is installed on the gear shaft 8, also be provided with the modified gear 6 with driven gear 5 coaxial settings in the casing 11, the number of teeth difference of the number of teeth of modified gear 6 and driven gear 5 one or more; Modified gear 6 and driving gear 4 engagements, indicator panel 3 is installed on the modified gear 6, and pointer 2 is installed in the end that gear shaft 8 stretches out casing 11, and casing 11 is wholely set with loam cake 12.
Above-mentioned indicator panel 3 is installed on the modified gear 6 by rivet 31; Driving gear 4 is installed on the valve rod 7 by flat key 41; Be provided with the boss 111 that supports driving gear 4 in the above-mentioned casing 11, be provided with pad 42 between boss 111 and the driving gear 4.
The utility model reaches the displacement effect by the driven gear 5 of coaxial setting is arranged to the different numbers of teeth with modified gear 6, driven gear 5 is fixedlyed connected with gear shaft 8, gear shaft 8 ends are provided with pointer 2, and indicator panel 3 is arranged on the modified gear 6, because the number of teeth difference of these two gears, revolution moves a week, just produces differential seat angle between these two gears, constitutes the displacement system of angle of swing; And can be by the design to the number of teeth of driven gear 5 and modified gear 6, make pointer 2 point to unique opening value that any point on the indicator panels 3 all represents valve; Casing 11 and the loam cake 12 of gear-box 1 are wholely set, and have made things convenient for manufacturing, and the pad 42 between the boss 111 of driving gear 4 and casing 11 can play the effect that reduces to wear and tear.The utlity model has advantage simple in structure, that volume is little, easy to process.
