Abstract
The invention discloses a jet device throat pipe current-limiting component which comprises a throat pipe and a current-limiting cover, wherein the end of the throat pipe is provided with two holes; a blocking groove is formed in the inner side of the end of the throat pipe; the current-limiting cover is blocked at the end of the throat pipe; the current-limiting cover is also provided with a hole; the current-limiting cover is matched with a port on the top of the throat pipe. According to the jet device throat pipe current-limiting component, a current-limiting plate is arranged at the end of the throat pipe, so that the current limiting capacity is improved.
Description
Technical field
The present invention relates to a kind of current limliting assembly, be specifically related to a kind of ejector trunnion current limliting assembly.
Background technology
Ejector trunnion assembly is in the past the tubular body trunnion that a single end has two holes, this trunnion has certain metering function in ejector, but current limiting capacity a little less than, when in order to obtain with little flow, ejector trunnion assembly also cannot meet the demands.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of ejector trunnion current limliting assembly, improved current limiting capacity.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
An ejector trunnion current limliting assembly, comprises trunnion and current limliting lid, and described trunnion end is provided with two holes, inner side, end is provided with draw-in groove, described current limliting lid is connected to trunnion end, and described current limliting covers and is also provided with hole, and described current limliting lid mates with trunnion top port.
Described trunnion is tubular body, and the tube wall thick middle two ends of tubular body are thin.
Beneficial effect: the present invention, by establishing a current limiting plate in trunnion end, has improved current limiting capacity.
Accompanying drawing explanation
Fig. 1 structure chart of the present invention.
The connection enlarged drawing of Fig. 2 trunnion and current limiting plate.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As illustrated in fig. 1 and 2: a kind of ejector trunnion current limliting assembly, comprise trunnion and current limliting lid, described trunnion end is provided with two holes, inner side, end is provided with draw-in groove, described current limliting lid is connected to trunnion end, and described current limliting covers and is also provided with hole, and described current limliting lid mates with trunnion top port.
Described trunnion is tubular body, and the tube wall thick middle two ends of tubular body are thin.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
