Problems solved by technology

[0003] At present, the cut-off of the cooling water pipeline is controlled by a pneumatic valve. The pneumatic valve is connected to the compressed air. The pressure of the compressed air is generally 4kg~6kg. Due to the excessive pressure, the pneumatic valve will be closed directly, so that the cooling water will hit the pipeline. and pneumatic valves, causing huge noise pollution. Therefore, it is necessary to develop a device that can adjust the compressed air pressure to avoid the noise caused by the impact of cooling water. After searching, no device identical or similar to the device of the present invention was found.

Embodiment 1

[0016] The pneumatic control valve includes an actuator 3 and a valve body 2. The valve body 2 is installed on the cooling water pipeline 1. The actuator 3 is connected to the air source through the air pipe 5. The adjustment mechanism 4 is arranged on the air pipe 5 between the actuator 3 and the air source. Above, the decibel control mechanism includes a decibel detector 6 and its controller 7. The decibel detector 6 is arranged on the valve body 2 and is connected to the controller 7 through a data line, and the controller 7 is also connected to the adjustment mechanism 4 through a data line.

[0017] The data detected by the decibel detector 6 enters the register, and then the analog signal data is converted into digital signal data through A / D conversion and transmitted to the controller. The controller makes a judgment based on the digital signal data, thereby controlling the regulating valve to adjust the air pressure.

Embodiment 2

[0019] The pneumatic control valve includes an actuator 3 and a valve body 2. The valve body 2 is installed on the cooling water pipeline 1. The actuator 3 is connected to the air source through the air pipe 5. The adjustment mechanism 4 is arranged on the air pipe 5 between the actuator 3 and the air source. Above, the decibel control mechanism includes a decibel detector 6 and its controller 7. The decibel detector 6 is arranged on the valve body 2 and is connected to the controller 7 through a data line, and the controller 7 is also connected to the adjustment mechanism 4 through a data line.

[0020] The data detected by the decibel detector 6 enters the register, and then converts the analog signal data into digital signal data through A / D conversion and transmits it to the controller, and the controller converts the digital signal data into analog signal data through D / A conversion. The signal data can be displayed on the PC through graphs or tables, and the controlle...

Abstract

The invention relates to a noise-proof pneumatic regulating valve, which is installed on a cooling water pipe. The noise-proof pneumatic regulating valve comprises a pneumatic regulating valve, a regulating mechanism and a decibel control mechanism, wherein the pneumatic regulating valve comprises an actuating mechanism and a valve body, the valve body is installed on the cooling water pipe, the actuating mechanism is connected with an air source through an air pipe, the regulating mechanism is arranged on the air pipe between the actuating mechanism and the air source, the decibel control mechanism comprises a decibel detector and a controller thereof, the decibel detector is arranged on the valve body and is connected with the controller through a data line, and the controller is connected with the regulating mechanism through a data line. The noise-proof pneumatic regulating valve has the advantages that the device firstly measures noise data of the cooling water circulating pipe through the decibel detector, analog signal data enters a register and is converted into a digital signal data through A / D conversion to enter the controller, the controller controls the regulating valve according to data change and thus noise pollution is avoided.

Description

technical field [0001] The invention relates to a regulating valve, in particular to an anti-noise pneumatic regulating valve. Background technique [0002] With the rapid development of industry, the Environmental Protection Bureau has stricter and stricter requirements for industrial environmental assessment. [0003] At present, the cut-off of the cooling water pipeline is controlled by a pneumatic valve. The pneumatic valve is connected to the compressed air. The pressure of the compressed air is generally 4kg~6kg. Due to the excessive pressure, the pneumatic valve will be closed directly, so that the cooling water will hit the pipeline. And pneumatic valve, cause huge noise pollution, therefore, just must develop a kind of device that can adjust compressed air pressure so as to avoid cooling water collision to cause noise, after searching, find no identical or similar device with the device of the present invention. Contents of the invention [0004] The technica...
