Description
Technical field
The utility model relates to hydraulic butterfly valve technical field, more particularly, and particularly a kind of locking device of heavy hammer type hydraulic butterfly valve.
Background technique
The locking device of existing heavy hammer type hydraulic butterfly valve is structurally comparatively complicated, and while keeping weight potential energy, have the generation of oil leakage phenomenon more.Turn increase a set of hydraulic pressure installation for subsequent use as outside the oil hydraulic circuit that opens and closes at normal control valve, in its structure, more complicated and oil leakage phenomenon does not solve completely.And CN200820069664.3 discloses a kind of locking device of heavy hammer type hydraulic butterfly valve, it adopts connecting lever, strut, electromagnet and block to realize the locking of weight, although it can realize lock function, but in the locking moment of weight, strut bears larger power, easily occurs that the phenomenons such as damage occur.Therefore, be necessary to improve the locking device of existing heavy hammer type hydraulic butterfly valve.
Model utility content
The purpose of this utility model is to provide a kind of locking device avoiding strut to occur the heavy hammer type hydraulic butterfly valve damaged.
In order to solve problem set forth above, the technical solution adopted in the utility model is: a kind of locking device of heavy hammer type hydraulic butterfly valve, for locking weight, comprise frame, connecting lever, electromagnet, strut and the block be fixedly connected on weight, described electromagnet is fixedly installed in frame, described connecting lever rotates to be installed in frame and with the motion end of electromagnet and is connected, Returnning spring is provided with between described connecting lever and frame, described strut is installed in frame, and the top of described strut one end, bottom respectively with connecting lever, block forms the press fit of departing top, described frame is also provided with disc spring groove, dished spring assembly is provided with in described disc spring groove, one end that described strut and connecting lever match compresses with dished spring assembly and contacts.
According to a preferred embodiment of the present utility model: the disc spring that described dished spring assembly is superposed mutually by many groups forms.
According to a preferred embodiment of the present utility model: one end of described strut is also connected with handle.
According to a preferred embodiment of the present utility model: the top of one end of described strut and bottom are respectively equipped with projection, retaining groove, the bottom of described connecting lever is provided with the groove coordinated with projection, and described block matches with retaining groove.
Compared with prior art, the beneficial effects of the utility model are: the utility model have employed dished spring assembly and strut and to offset press contacts, in the locking moment of weight, can offset the power that weight applies strut, avoid strut to occur damaging, extend the working life of locking device.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the locking device of heavy hammer type hydraulic butterfly valve of the present utility model.
Description of reference numerals: 1, weight, 2, connecting lever, 3, Returnning spring, 4, electromagnet, 5, handle, 6, strut, 7, groove, 8, projection, 9, dished spring assembly, 10, disc spring groove, 11, block.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, the utility model provides a kind of locking device of heavy hammer type hydraulic butterfly valve, for locking weight 1, and the block 11 comprising frame, connecting lever 2, electromagnet 4, strut 6 and be fixedly connected on weight 1.
Described electromagnet 4 is fixedly installed in frame, described connecting lever 2 rotates and is installed in frame and is connected with the motion end of electromagnet 4, Returnning spring 3 is provided with between described connecting lever 2 and frame, described strut 6 is installed in frame, and the top of described strut 6 one end, bottom form the press fit of departing top with connecting lever 2, block 11 respectively.
The utility model is also also provided with disc spring groove 10 in described frame, is provided with dished spring assembly 9 in described disc spring groove 10, and one end that described strut 6 and connecting lever 2 match compresses with dished spring assembly 9 and contacts.
The disc spring that dished spring assembly 9 in the utility model is superposed mutually by many groups forms.
One end of strut 6 in the utility model is also connected with handle 5.
Top and the bottom of one end of the strut 6 in the utility model are respectively equipped with projection 8, retaining groove, and the bottom of described connecting lever 2 is provided with the groove 7 coordinated with projection 8, and described block 11 matches with retaining groove.
The working procedure of the locking device of heavy hammer type hydraulic butterfly valve of the present utility model is: when hydraulic mechanism is by valve open, when weight 1 rises to a high position, electromagnetic actuation of the present utility model under the signal that open bit line journey switch provides, connecting lever 2 is driven to rotate clockwise, projection 8 is made to enter in groove 7, and then push down strut 6 by connecting lever 2, strut 6 is pressed down and hooks the top bump of block 11, thus stop block 11, the whereabouts of weight 1, to offset press contacts owing to have employed dished spring assembly 9 and strut 6 simultaneously, can in the locking moment of weight 1, offset the power that weight 1 pair of strut 6 applies, avoid strut 6 to occur damaging, extend the working life of locking device, and in power-off or when closing valve, electromagnet 4 power-off, its motion end departs from, and connecting lever 2 rotates counterclockwise under the effect of Returnning spring 3, thus release strut 6 and block 11, weight 1 falls and throttle down under the effect of self potential energy.
Above-described embodiment is the utility model preferably mode of execution; but mode of execution of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
