Embodiment
Like Fig. 1; Shown in Figure 2, the utility model provides a kind of band location Lock valve handle, matches with spacing, locking device on the valve; Can realize that the limit when lever operated is spacing; Avoid the improper valve that firmly causes to damage, can also utilize it that valve is fixed on unlatching, closes or other intermediatenesses, avoid misoperation.This band location Lock valve handle is provided with the valve joint 1 and holding part 2 that is fixed together; Also be provided with the boss that is fixedly connected with said valve joint and/or holding part; Said boss is provided with lockhole 5; This lockhole can cooperate the lock operation of realization to valve with the corresponding lockhole on the valve, avoids the generation of misoperation.Concrete quantity of this lockhole and position can cooperate the quantity of the limit stoper on the valve and position to be provided with.
The profile of said valve joint is preferably approximate circle cylinder broad in the middle, that two is little, and this cylindrical bus is a smoothed curve.Than the cylindrical body of rule, the structural strength of the valve joint of this shape is better, and it is easier that processing (like casting) is got up.
Said valve joint middle part is provided with valve attachment hole 7, and said valve attachment hole can be polygonal hole, is preferably cubic hole, it is understandable that, the shape of said valve attachment hole can be according to the shape setting of the tenon of the valve rod that is mated.
Said band location Lock valve handle is that cast inblock forms, and is preferably and adopts silica sol precision casting technology to cast.
Said holding part is made up of neck that is connected 3 and shank 8; Said neck and shank are tabular; And the angle between the two plate face is the obtuse angle, and the outside that said neck can be connected said valve joint is portion on the upper side, and said shank bearing of trend can be parallel with the bottom plane of said valve joint; And the horizontal position of shank generally should be higher than said valve joint; Certainly, the situation of valve during according to concrete the application, the bearing of trend of said shank can be not parallel with the bottom plane of said valve joint yet.
For above-mentioned any valve handle, can also be provided with on it with said valve joint and/or holding part being used for of being fixedly connected and cooperates the said holding part of qualification to move one or more positioning blocks of angle with limit stoper on the valve.
Like Fig. 1, shown in 2, said positioning block can comprise positioning block a4 and positioning block b6, is responsible in the location/limit of valve wide open and full cut-off situation lower valve handle spacing respectively.And be respectively equipped with locating face a and locating face b (corresponding respectively to the horizontal upper edge of positioning block a4 and positioning block b6 shown in Figure 2) on it.Preferably; Said locating face a and locating face b coplane; And the distance of the rotational axis line of the said valve joint of distance equates; During actual the use, locating face a and locating face b can match with the same limit stoper on the valve and realize respectively closing and operating by closing out two kinds of spacing valve handles of the band location/limit by reaching.Explain through a simple embodiment how the band location Lock valve handle of the utility model is used in the spacing operation of the location/limit below:
Fig. 3, the residing location status of valve handle when being respectively valve wide open, complete shut-down shown in 4; Valve handle is installed in the top of the flange platform 9 of valve; One hexagon socket head cap screw 10 is installed in the hole in the upper right corner of flange platform (illustrated orientation), bolt head be exposed at flange platform table top above.When valve handle during by the position of Guan Xiangkai rotation (promptly being rotated counterclockwise); Locating face b runs into the bolt head of hexagon socket head cap screw 10, representes that promptly valve handle has rotated to the theoretical limit position of opening, and valve just is in the full open state; At this moment; Lockhole 5 is just aimed at the hole in the lower right corner (illustrated orientation) of flange platform, at this moment on lockhole and flange platform, inserts locating stud or the bolt position of fixed valve handle effectively in the corresponding hole, prevents that the people from being misoperation.When wanting throttle down, the bolt that takes out aforesaid locating stud or replace locating stud to use is earlier moved valve handle and is turned clockwise; When locating face a runs into the bolt head of hexagon socket head cap screw 10; Represent that promptly valve handle has rotated to the theoretical limit position of closing, valve just is in full closing state, at this moment; Lockhole 5 is just aimed at the hole in the lower left corner (illustrated orientation) of flange platform; Again aforesaid locating stud or the bolt that replaces locating stud to use are inserted on lockhole and the flange platform in the hole corresponding with it,, prevent that the people from being misoperation so that valve handle is fixed on closed position reliably.It is thus clear that the setting of positioning block a and b not only can avoid the valve ON/OFF not in place, also can avoid the excessive rotation of valve handle, thereby avoid the damage of valve handle.
It is understandable that the particular location of the said positioning block a of the utility model, positioning block b and boss all is that the actual conditions of the limit stoper (like aforesaid flange platform 9 and hexagon socket head cap screw 10) on the basis valve that is mated are provided with.
Said positioning block a, positioning block b and boss three common guarantee good spacing, the lock-bit effect of this valve handle; Better agree with valve in practical operation for the ease of this valve handle, the bottom surface of said three's bottom surface and said valve joint preferably is in same horizontal plane.
The upper surface of said holding part and/or lower surface can be provided with holds groove, and the said groove of holding is preferably designed to the waveform that meets the human body hand-type and holds groove, increases comfort level, also can be with rubber sleeve outward for comfort level is better.
The thickness of said shank promptly under the situation that intensity meets the demands, carries out loss of weight and handles preferably less than neck.The end of said shank can be provided with through hole, can serve as suppending hole.
