　　PE管钢制体排气球阀是RETZ在球阀领域的重大研究成果：一种钢塑混合型球阀。其主体部分采用锻钢球阀结构，与管道连接部分采用PE(聚塑料)接管。这种钢塑复合设计避免了纯PE球阀在长期使用中因阀体及操作部分材质老化而导致开关失效及损坏的弊端，所以不易产生因PE老化损坏后引起的泄露，使用寿命长并且安全可靠，不易产生外漏及因PE材料老化损坏以后而导致的纯PE球阀出现泄露The PE pipe steelexhaust ball valve is a major research achievement of RETZ in the field of ballvalves: a steel plastic mixed ball valve. The main body adopts a forged steelball valve structure, and the connection part with the pipeline adopts PE(polyethylene plastic) pipes. This steel-plastic composite design avoids thedrawbacks of switch failure and damage caused by the aging of the valve bodyand operating materials in the long-term use of pure PE ball valves. Therefore,it is less prone to leakage caused by PE aging and damage, has a long servicelife and is safe and reliable, and is not prone to external leakage and pure PEball valve leakage caused by PE material aging and damage.

　　进口钢制PE放散球阀主要特点DESIGN FEATURES

　　钢制PE球阀克服了纯PE球阀因材料老化而导致的阀门主体泄漏问题以及操作器和加长杆容易扭断或长期动作磨合之后开关失效的情况。

　　PE-Forged-Steelball valve overcomes the leakage problem of pure PE ball valve body due tomaterial

　　agingand operator and an extension rod easily break or after the long-term action ofrunning switch failure.

　　钢制PE球阀采用双向密封阀座结构，相比于常规聚四阀座，密封性能更加可靠牢固可靠。

　　PE-Forged-Steelball valve using a two-way sealing valve seat structure, compared to theconventionalPTFE valve seat, the sealing performance is more reliable and firmand reliable.

　　钢制PE球阀为安全防火型阀门：金属复合密封阀座，当阀座上的软密封材质被烧毁以后，可通过金属阀座在蝶形弹簧预载力的作用下被充软密封空间，压紧球体，形成金属对金属的密封结构。

　　PE-Forged-Steelball valve is fire safty valve: metal composite sealing valve seat, when thesoft sealing material onthe seats was bumed, the metal seat under the butterflyspring preload force will supply soft sealing space, pressingball, formingmetal to metal seal structure.

　　钢制PE球阀阀杆设杆为防飞倒穿型，设置带有密封垫片的倒密封结构，倒密封的密封效果随阀腔压力的增高而增大，阀杆采用O型圈密封；阀门的启闭力矩较小，阀杆使用锻钢件，使用寿命长，强度高。

　　PE-Forged-Steelball valve is designed to stem the anti-wear type fly inverted, set dowen witha gasket seal structure,sealing effect increased with valve chamber pressureincreasing, the valve stem sealing with an O-ring seal; valveopening andclosing torque is small, the stem is forged steel materia which has long lifeand high strength.
