Description
Technical Field
The utility model relates to an air conditioner, in particular to a gas flow dividing device for an air conditioner.
Background
The flow divider is an auxiliary device between the expansion valve and the evaporator in the air-conditioning refrigeration system, and is used for uniformly and equally distributing gas or liquid from the expansion valve to the flow dividing pipes of the evaporator. The traditional flow divider generally comprises a main flow pipe and uniformly distributed branch pipes, and although the uniform distribution of gas to each branch pipe can be basically realized, when the flow divider is used, each branch pipe is always in an open state, so that the flow divider can only be used for distributing rated gas. When the liquid or gas flow changes or not need to use whole shunt tubes, can only change new shunt, change and waste time and energy, and use cost is high.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides the air-conditioning gas flow distribution device which can realize the automatic control of the opening and closing of each flow distribution pipe, solve the problem that the traditional flow divider can only quantitatively distribute gas, and further realize the flow distribution of different amounts of gas or liquid.
The technical scheme adopted by the utility model is as follows: a gas flow dividing device for an air conditioner is characterized in that: including the pipeline body, the head of the pipeline body is axial sprue, and the middle part of the pipeline body sets up the toper water conservancy diversion body that corresponds sprue, and the rear portion of the pipeline body sets up the axial of multichannel and forms, communicates sprue's reposition of redundant personnel passageway through toper water conservancy diversion body reposition of redundant personnel, set up the ball valve on the reposition of redundant personnel passageway, the external pneumatic actuator of ball valve.
Furthermore, the ball valve is installed on the rear end face of the pipeline body and is in compression joint through the connecting flange.
Furthermore, the pneumatic actuating mechanism comprises a cylinder body, a gear, a rack, pistons, a spring and an electromagnetic reversing valve, wherein the gear is arranged in the middle of the cylinder body, two pistons are arranged on two sides in the cylinder body respectively, the back of each piston is abutted against the cylinder body through the spring, the two pistons are connected with the rack on the upper portion and the rack on the lower portion towards the middle respectively, the gear is meshed between the two racks, the gear is connected to a valve rod of the ball valve in a penetrating mode, and an air source is connected with an inner cavity between the two pistons of the cylinder body through the electromagnetic reversing valve.
Furthermore, the electromagnetic directional valve is a two-position three-way electromagnetic directional valve.
Further, the valve rod penetrates through the outer side wall of the pipeline body and is in compression joint through the pressure plate.
The pipeline body is supplied with air from the main flow channel and uniformly dispersed to each flow dividing channel through the conical flow guide body, thereby realizing uniform distribution of the air. The ball valve is installed in each flow distribution channel, automatic control over the ball valve is achieved through the pneumatic actuating mechanism, then automatic opening and closing of each flow distribution channel is controlled, time and labor are saved, flow distribution devices of different specifications do not need to be replaced, and the ball valve is convenient to use and low in cost.
