Problems solved by technology

The current T-type high-temperature air valve has the following problems: 1) Due to heat conduction, the actuator is overheated and easily damaged; 2) The actuator and the two valve disc transmission connecting rods are located on both sides of the air valve, and the valve shaft is installed with the transmission connecting rod The length of the valve not only makes the heat preservation of the valve body more troublesome, but also the transmission effect is not good; 3) The installation of the valve shaft arm is cumbersome, and the rotation synchronization of the two blades is poor. It is difficult to ensure that one valve slice is fully opened and the other valve slice is fully opened Closed performance requirements

Abstract

The invention relates to a valve, in particular to an air valve. The air valve comprises a horizontal valve body and a vertical valve body which are connected in a T shape, wherein flanges are connected to two ends of the horizontal valve body and the upper end of the vertical valve body, a bracket is fixedly connected to the outer side wall of the vertical valve body through a positioning plate, a bracket fixing plate is mounted in the bracket, a sunk screw penetrates through an actuator fixing plate and is fixed on an insulation mica ring b in the bracket and insulation mica pads on two sides of the bracket, so that the actuator fixing plate is fixedly connected with the bracket in an insulation manner, and an insulation transmission mechanism is located in the bracket. The air valve has the benefits as follows: tumblers and a compression arm are fastened by hexagon socket head cap screws, so that consistency of angles of the two tumblers and corresponding valve plates, that is, the rotation synchronism of the valve plates, is guaranteed; by means of the assembling structures of a spindle connecting sleeve and a spindle rotating disc as well as an actuator connecting shaft and an insulation rotating disc, driving force of an actuator can be transmitted effectively.

Description

technical field [0001] The invention relates to a valve, in particular to a damper. Background technique [0002] In the ventilation pipeline system, the valve is the control element, and its main function is to isolate the equipment and the pipeline system, regulate the flow, prevent backflow, adjust and discharge the pressure, so the valve is a crucial device in the ventilation pipeline system. In RTO exhaust gas treatment and automobile painting ventilation systems, three ventilation valves are usually used. The two valves are linked to open and close in opposite actions. The two valves are driven by a large torque pneumatic or electric actuator. The gas in the pipeline The temperature is above 500°C, and the intermittent maximum temperature is sometimes 1200°C. The current T-type high-temperature air valve has the following problems: 1) Due to heat conduction, the actuator is overheated and easily damaged; 2) The actuator and the two valve disc transmission connecting r...
