Description
Technical field
The utility model relates to a kind of valve part, is specifically related to a kind of quickly assembled and disassembled handwheel that is used for valve.
Background technique
When valve being opened and closed the adjustment of operation or aperture, need to use handwheel usually.Common handwheel structure is, the handwheel main body comprises a circular rim, and the central authorities of rim are provided with wheel hub, connects through spoke between rim and the wheel hub, and wheel hub is provided with the hole that cooperates with the valve rod connecting head of valve.During use, wheel hub is set on the valve rod connecting head, adopts screw or bolt to fix usually.Therefore, need install or the screw that gets loose with instrument during the handwheel dismounting of said structure,, generally all be installed on the valve rod because dismounting is not very convenient.Like this, when there was a plurality of similar valve in a certain zone, each valve all needed to install a handwheel; And, be easy to take place the handwheel steal phenomenon in some occasion.
Therefore, if a kind of quick change handwheel can be provided, can address the above problem.
Summary of the invention
The utility model purpose provides a kind of valve quick change handwheel, to adapt to the needs of various different use occasions.
For achieving the above object, the technical solution adopted in the utility model is: a kind of valve quick change handwheel, comprise the handwheel main body, the wheel hub of described handwheel main body central authorities is provided with the mounting hole that cooperates with the valve rod connecting head of valve, on the sidewall of described wheel hub, be provided with the through hole that is communicated with described mounting hole, cooperate with described through hole, be provided with rapid-changing structure, described rapid-changing structure comprises, one is provided with the spring seat in the hole of bottom closure, the opening end of spring seat is fixedlyed connected with wheelboss side wall, and described through hole is aimed in the hole on the spring seat, is provided with pin in the hole, the afterbody of pin is fixedly connected with the V-arrangement pin, be relatively set with seam on the sidewall of spring seat, the two ends of V-arrangement pin pass described seam respectively and are slidingly connected with described seam, are provided with Returnning spring between at the bottom of the hole of V-arrangement pin and spring seat, at reset position, the front end of described pin stretches into mounting hole, and at compression position, the front end of described pin is positioned at described through hole.
Above, described handwheel main body is a prior art, can adopt ring-type rim, spoke, wheel hub structure, also can add handle on the ring-type rim, can also adopt the handwheel main body that wing formula structure is set on wheel hub, perhaps the handwheel main body of other existing structure.As long as being connected the cooperation place in the handwheel main body with the valve rod connecting head is provided with described through hole and rapid-changing structure, promptly belong to protection domain of the present utility model.
In the technique scheme, the fixed connection structure of the afterbody of described V-arrangement pin and described pin is, is provided with the hole vertical with the moving direction of pin at the afterbody of described pin, and the stage casing of described V-arrangement pin is arranged in the described hole.
During installation, pulling V-arrangement pin, pressure spring is drawn in the front end of pin in the through hole on the wheel hub, the handwheel main body can be inserted in the valve rod connecting head, unclamps the V-arrangement pin, and under spring action, the front end of pin inserts in the pin-and-hole corresponding on the valve rod connecting head, i.e. the lockable handwheel.During dismounting, pulling V-arrangement pin, pressure spring is drawn in the front end of pin in the through hole on the wheel hub, can take off handwheel.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. the utility model can be realized the quick mounting and the dismounting of handwheel easily by rapid-changing structure is set, and both can install for a long time also and can install in real time.
2. because structure of the present utility model can quick mounting be dismantled, can realize the handwheel of the shared same specification of many deck valves door, reduce cost; In specific use occasion, handwheel can be taken away after each the use, avoid handwheel stolen.
