Description
Technical field
The utility model relates to a kind of Hand-operated butterfly valve handle, relate in particular to a kind ofly have release, locking adds the Hand-operated butterfly valve handle of lock function.
Background technique
Butterfly valve is to make open-shut device and rotate a kind of valve of opening, cutting out with the regulated fluid channel capacity with valve shaft with circular butterfly plate.Hand-operated butterfly valve is not only simple in structure, volume is little, in light weight, material consumption province, installation dimension is little, and driving moment is little, easy and simple to handle, rapid, having good flow regulating function and close sealing characteristics, is the optimum device that is used for making the adjusting flow on food, medicine, petrochemical industry, industrial environment and tall building and the pipeline and blocks fluid.Basically be the linear ratio relation between the valve plate aperture of butterfly valve and the flow,, must adopt the handle controlling mechanism that butterfly plate is stopped on the appropriate location for regulating flow.Existing Hand-operated butterfly valve regulating handle mainly comprises handle body and stop dial, and stop dial suit valve shaft is fixedly mounted on the valve body on the axle head cover port, and its card front end scale side is provided with limited post, after the card along being provided with some teeth groove; Handle body comprises straight-bar type master handle and is positioned at the secondary handle of hook shape of main handle bottom, secondary handle hook top is hinged by pin and main handle, secondary handle forearm end is provided with between card point, postbrachium and main handle and is connected by locking spring, really make the card point of forearm end under the elastic force effect snap in the teeth groove of stop dial, main handle front end is provided with the limiting board of band arc spacing hole, and the limiting board of main handle is pressed on the stop dial with its arc spacing hole suit limited post and main handle is fixedlyed connected with valve shaft by screw.When carrying out the adjusting of valve plate aperture, hold main handle and clutch auxiliary-handle, length of spring compressed, make secondary handle forearm end descending, card is sharp throws off with teeth groove, and major and minor handle discharges, and rotates main handle and then makes valve shaft drive the valve plate rotation, after being adjusted to proper angle, discharge secondary handle, under the effect of spring reset elastic force, secondary handle forearm end upwards lifts and resets, the card point inserts teeth groove again, makes major and minor handle braking.The major defect of existing Hand-operated butterfly valve is: (1) can not be thoroughly locked, to restriction operation and there is crowd's occasion can not guarantee that butterfly valve is failure to actuate; (2) can not thoroughly discharge, arbitrarily operation; To the very difficult place that arrives of staff,, can not be implemented in ground and realize opening the adjusting operation easily by special-purpose assistant tool as deep-well or high-lift operation; (3) existing main handle is a straight-bar type, and position, secondary handle postbrachium hand part also is a straight-bar shape, is not inconsistent with the staff curve, is affectedly bashful discomfort, and inconvenience firmly.
The model utility content
Main purpose of the present utility model is at the problems referred to above, on existing nothing lock handle arrangement basis, improve, provide a kind of and have release, locking adds the Hand-operated butterfly valve handle of lock function, promptly can be locked at the state that locks the state that to operate or discharge, arbitrarily operate by lock, thereby satisfy the needs of different operating modes, occasion, the operation of guarantee fluid line is normally conveniently carried out, and improves profile and use the more comfortable application of force operation of being convenient to.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of have the Hand-operated butterfly valve handle that discharges, lock state adds lock function, comprise handle body and stop dial, described stop dial suit valve shaft is fixedly mounted on the valve body on the axle head cover port, its card front end is provided with limited post near the central authorities of scale side, and the edge is provided with some teeth groove after the card; Handle body comprises bar shaped case shape master's handle and is positioned at the secondary handle of hook shape that main handle case bottom is made of forearm and postbrachium, secondary handle hook top is hinged by bearing pin and main handle housing, secondary handle forearm end is provided with the card point, a locking spring is connected between secondary handle postbrachium and the main handle, the card point of the forearm end under the elastic force effect is snapped in the teeth groove of stop dial, main handle front end is provided with the limiting board of band arc spacing hole, and the limiting board of main handle is pressed on the described stop dial with the described limited post of its arc spacing hole suit and main handle is fixedlyed connected with valve shaft by screw; It is characterized in that the card point of corresponding described secondary handle forearm end snaps in the locked position of the teeth groove of stop dial, cross the stop pin that main handle handle body and secondary handle forearm are provided with the energy disassembled and assembled freely, its keyed end is provided with lock, or the card point of corresponding described secondary handle forearm end is separated from the release position of the teeth groove of stop dial, cross main handle handle body and secondary handle postbrachium be provided with can disassembled and assembled freely stop pin, its keyed end is provided with lock.
Described main handle profile is the arch kink shape.
The postbrachium lower edge of described secondary handle is provided with and points corresponding inner concave arc surface.
The positive front end of the limiting board of described main handle is provided with tuning drive gear.
The beneficial effects of the utility model are: since existing do not have on the lock handle arrangement basis set up release, locking adds lock function, make butterfly valve on the application foundation of existing not operation with lock, increase by two kinds of new functions, promptly can be locked lock the state that to operate, can and have crowd's occasion to guarantee that butterfly valve is failure to actuate at restriction operation by lock; Or butterfly valve is in discharge, the random state of operation, like this in place that staff is difficult to get at, as deep-well or high-lift operation, then Handle of butterfly valve is locked in the state that discharges, arbitrarily operates, realize opening the adjusting operation on ground easily by special-purpose assistant tool like this; Especially will have straight-bar type master handle now and change the arch kink shape into, secondary handle postbrachium lower edge is provided with and points corresponding inner concave arc surface and staff curved surface and coincide, and is affectedly bashful comfortablely, is convenient to firmly.
