Abstract
The utility model discloses a round fireproof regulating valve capable of regulating air flow, which comprises a fairing, a driving shaft, a plurality of blades, a driver and inner supports, the fireproof regulating valve is mounted in a barrel, which is cylindrical, the fireproof regulating valve also comprises a flow guide unit (i.e., the fairing), by which the driver is covered, a bearing block is arranged at the axis of the barrel, and is fixed on the barrel by the inner supports, the fireproof regulating valve also comprises driven shafts, the driving shaft and the driven shafts are evenly circumferentially arranged, and the blades are mounted on the driving shaft and the driven shafts, and rotate along with the shafts. Since the fireproof regulating valve is of a round multi-blade split type structure and is provided with the flow guide unit, the fireproof regulating valve can solve the defect that the air flow flowing through the blade structures of the conventional fireproof valve and the conventional regulating valve can produce eddies, and therefore the fireproof regulating valve can bring ideal fluid characteristics to a nozzle or an air duct cooperating with the fireproof regulating valve.
Description
Technical field
The utility model relates to a kind of fire prevention modulating valve, particularly relates to a kind of circle fire prevention modulating valve of quantity-adjustable.
Background technique
Current, along with the development of urban construction, the use of central air-conditioner is very universal, and the air-supply technology of central air-conditioner is also in continuous development, and practicability, Security and the aesthetic property of blowing device all had more and more higher requirement.
According to the relevant technologies standard, must install fire-closing valve or modulating valve between the airduct of central air-conditioner and the exhaust outlet, common fire-closing valve or modulating valve are rectangular cross sections, resembling Ball shape nozzle, circular air blowing opening etc. then is circular cross section, thereby must install transition between the two additional and take over and just can effectively connect, this had both increased installation cost, had wasted installing space again.The circular fire-closing valve of the quantity-adjustable formula that this patent is applied for, modulating valve are invented at the problems referred to above.
Summary of the invention
At the problems referred to above, main purpose of the present utility model be to provide a kind of can with the central air-conditioner spout of blowing, integrated use such as airduct, the also circular fire-closing valve of the quantity-adjustable that can install and use separately, modulating valve, the utility model solves above-mentioned technical problem by following technical proposals: a kind of circle fire prevention modulating valve of quantity-adjustable, it comprises: comprise air guide sleeve, driving shaft, some blades, transmission device, inner support, described fire prevention modulating valve is installed in the cylindrical shell, it is characterized in that: described cylindrical shell is cylindric, there is a bearing support at described tubular axis place, described bearing support is fixed on the cylindrical shell by described inner support, and described fire prevention modulating valve also comprises driven shaft, and described driving shaft and driven shaft evenly distribute by circumferencial direction, some blade installation are on driving shaft and driven shaft, and and axle rotation together.
Wherein, described driving shaft and every axle of driven shaft one is through on the axis hole of cylindrical shell, and the other end is through in the hole of bearing support, is fixed with a cone gear on the every axle, and adjacent cone gear is meshing with each other.
Wherein, described driving shaft and the outside actuator that prevents fires connect, and fire prevention actuator in outside drives the center rotation of driving shaft around oneself, drive driven shaft simultaneously and rotate around center separately.
Positive progressive effect of the present utility model is: the structure of circular fire prevention modulating valve of the present utility model is circular leafy opposite opened, and flow guide device is housed, the blade structure that can overcome traditional fire-closing valve, modulating valve can make the air-flow of flowing through produce the defective of eddy current, thereby this fire prevention modulating valve can make the comparatively ideal fluid characteristicss of acquisition such as the spout that is mated or airduct.
