Problems solved by technology

If even the air duct is inconvenient to remove, the fire damper can only be barely aligned and installed, which will cause the overall deformation of the fire damper, and even the entire outer frame will be tilted to one side, causing serious damage

Abstract

The invention discloses a draw-out type fire control valve, which is capable of drawing a valve body, an actuator and a thermofusion device out together easily in order for maintenance and cleaning. Although a deformation happens to an outer frame, the normal work of vane groups cannot be influenced, an admission space for the thermal expansion is reserved and the detection range of the temperature of the gas in an air duct is enlarged. The draw-out type fire fighting fire resistance valve comprises a valve body, an actuator, a thermofusion device and a guide rail type outer frame; wherein, the valve body is positioned in the guide rail type outer frame; the guide rail type outer frame is slidingly connected with an upper side and a lower side of an outer frame of the valve body; the guide rail type outer frame is movably connected with the an outer back side of the outer frame of the valve body through a handwheel; the upper part and the lower part at the same side of the actuator are provided with a handle; the periphery of end faces at the left side and the right side of the guide rail type outer frame are respectively fastened with a left segment air duct and a right segment air duct through screws. The draw-out type fire control valve is mainly suitable for fire control and safety of the ventilating fire-resistant pipeline, in particular for the fire control and safety of the electrostatic fume purifying device.

Description

technical field [0001] The invention relates to fire-fighting and fire-fighting valves, in particular to a withdrawable fire-fighting and fire-fighting valve. Background technique [0002] A kind of existing fire damper is made up of valve body, actuator, hot-melt device. The valve body includes a valve outer frame and a vane group, both of which are tightly combined as a unified whole. The opening or closing of the vane group is driven by an actuator, which is mounted on the outer front side of the outer frame of the valve. The hot-melt device is composed of a bracket, a hot-melt piece and a spring pull rod. One end of the bracket is connected to the actuator casing, and the other end is suspended on the left inner side of the blade group. The spring pull rod and the hot-melt piece are installed in the bracket. One end of the fuse is connected, the other end is connected with the actuator, and the other end of the thermal fuse is fixed at the end of the bracket. When ins...
