Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a balanced oil temperature pneumatic valve. Background Art

[0002] The balanced oil temperature pneumatic valve is a key device specially used to control the oil temperature in the system. It is designed to achieve the balance and regulation of the oil temperature through pneumatic operation. It is a special function valve that changes the resistance coefficient by changing the opening of the valve core, and then controls the flow of oil to achieve the purpose of regulating the oil temperature. It is an efficient and reliable oil temperature control device, widely used in industrial refrigeration, HVAC and other systems.

[0003] After searching, the Chinese patent with application number CN201821470999.6 discloses a pneumatic butterfly valve, which sets the valve opening size gear for the opening and closing controller to adjust the valve opening size. Due to the large gear error, the valve is not closed tightly, causing fluid leakage, wasting energy, and the quality cannot be guaranteed, which seriously affects energy conservation and environmental protection. Therefore, air is used as the power source to control the automatic opening and closing of the butterfly valve to reduce the error. In addition, air has the advantages of being convenient and pollution-free, and is suitable for use in the fields of explosion-proof and flame-proof, and has broad application prospects in the fields of manufacturing and services.

[0004] The above-mentioned pneumatic valve still has some shortcomings during use, because the pneumatic valve is usually exposed to the air, and the humidity and floating dust and impurities in the air will fall on the surface of the pneumatic valve. When the pneumatic valve is left stationary for a long time, the dust and impurities will accumulate on the surface of the pneumatic valve, which can easily cause the surface of the pneumatic valve to be eroded by the dust and impurities generated during use, making it inconvenient to clean and maintain the surface of the pneumatic valve, increasing maintenance costs and reducing the service life of the pneumatic valve.
