Abstract
The utility model provides a planetary valve handwheel that can indicate positions. The valve handwheel takes a planetary gear cluster as a structure. The planetary gears are fixed to be a rotating shaft and driven by inner gears at an inner circle of the handwheel, so as to drive a sun gear and a valve stem; wherein, a single gear toggle mechanism is arranged on the inner circle of the handwheel, so as to dial a cycle number indicating device above the planetary gear fixing shaft to change the digital of the cycle number when the handwheel rotates a cycle. Besides, angel bisection digitals are positioned above an inside track of the handwheel. The digitals of the angle bisection and cycle number are fixed and can not be influenced by rotation of the handwheel, thereby the digitals of angel bisection and cycle number can be displayed clearly, which is favorable for reading.
Description
Technical field
The utility model relates to the valve hand wheel of a kind of tool position indication, refers in particular to the valve hand wheel of a kind of planetary tool position indication.
Background technique
In the application of air-conditioning or flow control, these air-conditionings or flow control valve need have angle five equilibrium and the number of turns indicator that is easily understood, to use as manual flow control and adjusting.
According to background technique, how rotatable position indicator reaches the circumference scale that moves back and forth up and down with the valve shaft rotation and shows, as the angle five equilibrium and the rotating cycle of expression valve opening.Other has the code table of use or wheel-drive mode design at intermittence that numeral is presented at respectively this angle five equilibrium and number of turns wheel card top, and the wheel disc axle is coaxial with valve rod.Angle five equilibrium and number of turns wheel disc can be placed on handwheel below or the handwheel face, the former can be completely fixed two demonstration digit positions and not rotate, and the latter's two digital wheel discs are fixed on the handwheel and rotate synchronously with handwheel.
The advantage of this technology is that mechanism design is simple, yet, shortcoming is that not good the causing of number of division word location read to be difficult for, and the scale numeral is to place the handwheel below to be covered by the thermal insulation quilt coating easily, the technology that for example preceding case patent DE4114864, GB2283301, GB2312731 etc. are disclosed.
Another prior art then uses code table or intermittently wheel-drive mode design, numeral is presented at respectively this angle five equilibrium and number of turns wheel card top, and the wheel disc axle is coaxial with valve rod.So, angle five equilibrium and number of turns wheel disc can be placed on handwheel below or the handwheel face, the former can be completely fixed two demonstration digit positions and not rotate (as preceding case patent US3450091, US3991702), and the latter's two digital wheel discs are fixed on the handwheel and rotate (as preceding case patent EP0688991 and US5769118 patent) with handwheel synchronously.So, the former advantage is covered for not insulation coating, and digital motionless reading is easy, but shortcoming is for only being useful in the reduced size valve, and this is because big handwheel will cover the digit position of demonstration; In addition, the latter's advantage is covered for not insulation coating, and shortcoming is then rotated on the handwheel for numeral shows to be positioned at, and the observer must think deeply and distinguishes or the mobile position when therefore reading, the danger that the observer is easy to generate slip.
The model utility content
