Description
Technical field
The utility model relates to the control valve field, is specifically related to a kind of gas flow control valve.
Background technique
What present existing gas flow regulating valve was more is the Electromagnetic Flow modulating valve, its principle is, an end at valve core rod is equipped with the stainless steel shell fragment, under state of a control not, shell fragment returns to formation state naturally, and when the other end by the electromagnetic attracting force valve core rod overcomes the shell fragment pulling force, valve core rod will produce trace movement, the movement travel of the big or small control valve core bar by electromagnetic force, thus the size of controlling cutoff hole reaches the purpose of adjust flux.But the movement travel of the shell fragment of this modulating valve is very little, so regulation range is very limited.
Chinese patent 101251204 B disclose a kind of gas flow regulating valve, and it comprises a modulating valve main body, are provided with an air inlet nozzle and an outlet nozzle on it, and described air inlet nozzle has a gradient; Described modulating valve main body one end axially is respectively equipped with this air inlet nozzle and outlet nozzle with overlooking on face, the other end is provided with the hollow inner chamber; One valve core rod, it is arranged in described modulating valve main body, and an end has the cone end that matches with described air inlet nozzle gradient; One valve core rod actuating mechanism in order to controlling the closed intensity of described valve core rod and described air inlet nozzle, thereby is controlled gas from the air inflow of described air inlet nozzle; Described valve core rod actuating mechanism comprises: a stepper motor is arranged on this hollow inner chamber end of described modulating valve main body; And a constant acceleration cam that is positioned at the hollow inner chamber of described modulating valve main body, it is connected with the output shaft of described stepper motor; The outer rim of wherein said constant acceleration cam and the end of described valve core rod lean; One spring is set on described valve core rod, and the fixed position, inside of one end and described modulating valve main body leans, and in order to provide restoring force to described valve core rod, the end of the other end and described valve core rod leans.This kind gas flow regulating valve has solved the existing problem of above-mentioned solenoid valve to a certain extent, but the setting of its complex structure, especially stepper motor and constant acceleration cam has not only increased the difficulty in the manufacture process, has also increased manufacture cost.
