一.概述Product Overview:
氣動法蘭調(diào)節(jié)球閥具有良好的保溫保冷特性,且閥門的通徑與管徑一致,同時又能有效降低管路中介質(zhì)熱量損失。主要用于石油、化工、冶金、制藥、食品等各類系統(tǒng)中,以輸送常溫下會凝固的高粘度介質(zhì)。
由于采用整體式結構,因而保溫球閥比一般球閥何種更小,重量更輕,且無外漏,密封性能良好,夾套采用碳素鋼管焊接比鑄造的更加耐壓牢固。根據(jù)管道需要,決定選用往復式(二位開關式)或彈簧復位式(常閉或常開式)??蛇x配控制附件:(1)單電控電磁閥(斷電進常閉或常開),(2)雙電控電磁閥(開關式),(3)閥位開關回訊器,(4)氣源處理三聯(lián)件。特殊使用環(huán)境(易燃易爆場合),何選防爆型。
Pneumatic flange ball valve with good thermal insulation characteristics of cold, and the diameter of the valve diameter and the same, while the media effectively reduce heat loss in the pipeline. Mainly used in petroleum, chemical, metallurgical, pharmaceutical, food and other types of systems will be solidified at room temperature in order to transport high-viscosity media.
As a result of the overall structure, and thus what kind of insulation ball valve than smaller, lighter, and no leakage, good sealing performance, the use of carbon steel welded jacket casting more pressure than solid. According to the pipeline needs, decided to use reciprocating (two switch-type) or spring return (normally closed or normally open). Optional control accessories: (1) single electronic control solenoid valve (normally closed or normally off into the open), (2) double solenoid valve (switching), (3) Limit switches back to the hearing, (4 ) triple gas source processing parts. Special use of the environment (explosive situation), what selection explosion-proof. |
