Abstract
The invention discloses a blind plate device capable of limiting currents. The device comprises a connecting plate, a blind plate and a throttling ring, wherein the blind plate is used for cutting off a pipeline completely, and the throttling ring is used for smoothing the pipeline completely. The device is characterized by further comprising at least one limiting ring used for limiting the currents; the thicknesses and the diameters of the blind plate, the throttling ring and the limiting ring are equal; the connecting plate connects the blind plate, the throttling ring and the limiting ring together circularly; and a rotary axle sleeve used for fixing and rotating the blind plate device conveniently is arranged in the center of the connecting plate. When circulation of the pipeline is required to be cut off completely, only the blind plate is required to be mounted; when the pipeline is required to be smoothed completely, only the blind plate device is required to rotate, and the throttling ring is mounted on the pipeline; and when the circulation of the pipeline is required to be limited, the corresponding limiting ring can be chosen to be rotated, and the limiting ring is mounted on the pipeline. The operation is simple and convenient, and the flexibility is higher.
Description
Technical field
The present invention relates to a kind of blind plate device, but be specifically related to a kind of blind plate device of current limliting.
Background technique
Blind plate plays isolation, cutting action, is the same with end socket, pipe cap, welding plug role.Blind plate sealing is a kind of dismountable seal arrangement, and the sealing of end socket does not prepare to open again.Because the blind plate sealing performance is good, for the system that need to isolate fully, generally all as reliable isolating means.8 word blind plates are exactly a solid circle with handle, and shape is as 8 words, and an end is blind plate, and the other end is restrictor ring, under usual condition, being in the system of isolation.Easy to use, while needing isolation, use the blind plate end, while needing normal running, use the restrictor ring end, also can be used for filling up simultaneously the assemblage gap of blind plate on pipeline, the more clearly position that it installs additional and state after installing, more have safety assurance.But the restrictor ring diameter of 8 word blind plates is identical with the caliber of pipeline, does not play throttling action, 8 word blind plates can only be realized cutting off completely or be unimpeded completely, and flexibility is lower.
Summary of the invention
For the problems referred to above, but main purpose of the present invention is to provide a kind of blind plate device of current limliting, and the user can select different restrictor rings to carry out throttling according to actual needs, and flexibility is high, simple to operation.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
But a kind of blind plate device of current limliting, comprise connecting plate, a blind plate for complete cutting out pipeline, a restrictor ring for complete unimpeded pipeline, is characterized in that, also comprises at least one restrictor ring for current limliting, described blind plate, restrictor ring and restrictor ring thickness equate, equal diameters, described connecting plate links together blind plate, restrictor ring and restrictor ring annular, and described connecting plate center is provided with one for fixing and facilitate the rotary sleeve of rotation blind plate device.
In the time of the complete cutting out pipeline circulation of needs, only need to install blind plate, in the time of the complete unimpeded pipeline of needs, only need the rotation blind plate device, restrictor ring is arranged on pipeline, when the needs restriction conduit circulates, can selects to rotate corresponding restrictor ring and be arranged on pipeline and get final product, simple to operate also very convenient, flexibility is larger.
Further, described restrictor ring can be that the different metal cirque of internal diameter can be also the solid metal circle that evenly is provided with several current limliting through holes on end face.Internal diameter is larger, and the metering function of restrictor ring is more weak; The gross area of current limliting through hole is larger, and the metering function of corresponding restrictor ring is also more weak.
The invention has the beneficial effects as follows: the user can select different restrictor rings to carry out throttling according to actual needs, and flexibility is high, simple to operation.
The accompanying drawing explanation
Fig. 1 is the structural drawing of 8 word blind plates of existing design;
But Fig. 2 is embodiment 1 the structural drawing of the blind plate device of a kind of current limliting of the present invention;
But Fig. 3 is embodiment 2 the structural drawing of the blind plate device of a kind of current limliting of the present invention;
The mark implication of accompanying drawing is as follows:
1: blind plate; 2: restrictor ring; 21: restrictor ring one; 22: restrictor ring two; 3: connecting plate; 4: rotary sleeve; 5: the current limliting through hole.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, so that those skilled in the art can better understand the present invention also, can be implemented, but illustrated embodiment is not as a limitation of the invention.
Fig. 1 is the structural drawing of the existing 8 word blind plates that design, and can only realize cut-out completely or unimpeded completely by restrictor ring 2 realizations by blind plate 1, and flexibility is lower.But Fig. 2 is embodiment's 1 structural drawing of the blind plate device of a kind of current limliting of the present invention, but a kind of blind plate device of current limliting, comprise connecting plate 3, a blind plate 1 for complete cutting out pipeline, a restrictor ring for complete unimpeded pipeline 2, at least one is for the restrictor ring of current limliting, blind plate 1, restrictor ring 2 and restrictor ring thickness equate, equal diameters, connecting plate 3 links together blind plate 1, restrictor ring 2 and restrictor ring annular, and connecting plate 3 centers are provided with one for fixing and facilitate the rotary sleeve 4 of rotation blind plate device.In the time of the complete cutting out pipeline circulation of needs, only need to install blind plate 1, in the time of the complete unimpeded pipeline of needs, only need the rotation blind plate device, restrictor ring 2 is arranged on pipeline, when the needs restriction conduit circulates, can selects to rotate corresponding restrictor ring and be arranged on pipeline and get final product, simple to operate also very convenient, flexibility is larger.Wherein restrictor ring can be the different metal cirque of internal diameter, and as shown in Figure 2, the quantity of restrictor ring is 2, i.e. restrictor ring 1 and restrictor ring 2 22, and the internal diameter of restrictor ring is larger, and the metering function of restrictor ring is more weak; Restrictor ring can be also the solid metal circle that evenly is provided with several current limliting through holes 5 on end face, and the gross area of current limliting through hole 5 is larger, and the metering function of corresponding restrictor ring is also more weak.The user, according to the real work needs, can select different internal diameters or different current limliting through holes 5.
These are only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; perhaps directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
