Abstract
The utility model relates to a valve opening device which is characterized by comprising a folding operating handle and a turn arm lever, wherein one end of the turn arm lever is connected with the folding operating handle through a bolt groupware, and the turn arm lever is provided with a connecting piece connected with a valve driving turn arm on a high-pressure/low-pressure switch cabinet and a locating piece capable of being installed on the valve driving turn arm. By using the valve opening device, a valve can be opened and closed.
Description
Technical field
The utility model relates to the high and low pressure technical field of electrical equipment, relates in particular to a kind of structure that is used for opening, closing when the high and low pressure switch cubicle overhauls the valve opening device of valve.
Background technology
The valve arrangement of existing high and low pressure switch cubicle is used for isolating electrified body under trystate, prevents the human body accidental shock, and valve arrangement need carry out opening and closing by circuit breaker cart.
And present valve arrangement must rely on operating personnel manually directly to draw back valve under test position is in closed condition, and this kind mode is relatively more dangerous, very easily causes operating personnel's electric shock accidents during operate miss, and fail safe is not high.
Therefore be necessary to provide a kind of being used for to open when the high and low pressure switch cubicle overhauls, close the valve opening device of valve to address the above problem.
The utility model content
The purpose of this utility model is to provide a kind of can guarantee personal safety, valve opening device of opening, closing valve when being used for the maintenance of high and low pressure switch cubicle simple in structure, easy to use.
For achieving the above object, the utility model provides a kind of valve opening device, it is characterized in that: comprise folding operation handle and connecting lever bar, one end of described connecting lever bar is connected with described folding operation handle by bolt assembly, wherein said connecting lever bar be provided with the high and low pressure switch cubicle on valve drive the connector that connecting lever is connected and can be installed in keeper on the valve driving connecting lever.
Preferably, described connector is arranged on the flex point place of described connecting lever bar, and it is provided with support, rotary sleeve.
Preferably, described keeper is provided with the backstay that can be installed on the valve driving connecting lever.
Preferably, this valve opening device also comprises the locking extension spring, and this locking extension spring can be arranged on the described folding operation handle.
The beneficial effects of the utility model are to adopt mechanical system to open and close valve, have guaranteed personal safety, and opening and closing state at valve can lock, rational in infrastructure, rapid operation, and profile is small and exquisite attractive in appearance.
Description of drawings
Fig. 1 is the structural representation that meets valve opening device of the present utility model;
Fig. 2 is the structural representation at another visual angle of valve opening device shown in Figure 1;
The schematic diagram that Fig. 3 is to use the valve opening device that valve is closed;
The schematic diagram that Fig. 4 is to use the valve opening device that valve is opened.
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Please refer to Fig. 1 and Fig. 2, the high and low pressure switch cubicle valve that novel valve opening device described in the utility model is used for the high and low pressure technical field of electrical equipment when maintenance safe opening and close.Shown novel valve opening device is made up of operation part and safety locking part two parts.Operation part comprises folding operation handle 1 and connecting lever bar 3, is used for the operation of valve.Safety locking partly is locking extension spring 2, is used for the locking of device after opening or closing valve.This valve opening device is two common in pairs uses normally.
As Fig. 1, folding handle 1 is connected with connecting lever bar 3 by bolt assembly 11, and collapsible the dwindling in bolt assembly 11 backs of dismantling is convenient for carrying.
One end of described connecting lever bar 3 is connected with described folding operation handle 1 by bolt assembly 11, and wherein said connecting lever bar 3 is provided with the connector that is connected with valve driving connecting lever 4 on the high and low pressure switch cubicle and can be installed in keeper on the valve driving connecting lever 4.Described connector is arranged on the flex point place of described connecting lever bar 3, and it is provided with support, rotary sleeve 31.Described keeper is provided with the backstay 33 that can keep out on valve driving connecting lever 4.
The valve opening device also comprises locking extension spring 2, and this locking extension spring 2 can be arranged on the described folding operation handle 3.Locking extension spring 2 is used for device and is connected with the locking of cabinet when valve is opened or closed.
Please refer to Fig. 3, valve drives connecting lever 4 and is connected with upper and lower valve 6 by valve connecting rod 5.Under inspecting state: elder generation is sleeved on the rotary sleeve of the connector of the connecting lever bar 3 of device on the rotating shaft of valve driving Abduction arm 4, the keeper of connecting lever bar 3 with device is loaded on the lower edge that valve drives Abduction arm 4 again, pushing folding handle 1 to upper and lower valve 6 downwards closes, to lock extension spring 2 simultaneously and articulate and be locked on the cabinet, finish the purpose that valve is closed.
Please refer to Fig. 4, under inspecting state: elder generation is sleeved on the rotary sleeve of the connector of the connecting lever bar 3 of device on the rotating shaft of valve driving Abduction arm 4, the keeper of connecting lever bar 3 with device is loaded on the upper edge that valve drives Abduction arm 4 again, upwards lifting folding handle 1 to upper and lower valve 6 opens, to lock extension spring 2 simultaneously and articulate and be locked on the cabinet, finish the purpose that valve is opened.
Although below in conjunction with the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protected, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
