卫生级米勒制药用真空法兰生产厂家

详细介绍：下面我们说一下真空法兰相关的几大分类：超高真空法兰，拧紧型真空快卸法兰，加紧型真空快卸法兰。

超高真空法兰：适用于超高真空系统中不美标法兰锈钢法兰连接，采用铜垫密封。法兰允许烘烤温度为450摄氏度（具体结构及尺寸可见GB6070-85）。

拧紧型真空快卸法兰：适用于低、中、高真空管路，采用O型橡胶密封圈密封。此结构螺母材料采用碳钢、不锈钢、铝合金或硬塑料ABS（黑色）等。尾管材料可采用碳钢或不锈钢，若采用碳钢时，则表面需要镀镍，尾管的密封面粗糙度为20，但不得有明显的径向凹沟和刻痕。

加紧型真空快卸法兰：加紧型真空快卸法兰适用于低、中、高真空管路，用O型橡胶密封圈密封。此结构的连接盘材料采用碳钢或不锈钢，若采用碳钢时，则表面需要镀镍，卡箍材料采用铸铝ZL7.连接盘的密封粗糙度为20，并不得有明显的径向凹沟和刻痕。具体结构可见GB4982-85。

The following we talk about the vacuum flange related to several categories: ultra-high vacuum flange, tight vacuum quick-release flange, tight vacuum quick-release flange. Ultra-high vacuum flange: apply to ultra-high vacuum system stainless steel flange flange connection, using copper gasket seal. The permissible baking temperature of flange is 450 °C (see GB6070 -85 for the specific structure and size) . Tightening type vacuum quick-release flange: suitable for low, medium and high vacuum pipeline, using O-type rubber sealing ring to seal. This structure nut material uses the carbon steel, the stainless steel, the aluminum alloy or the hard plastic ABS (black) and so on. The liner material can be carbon steel or stainless steel, if the use of carbon steel, the surface needs nickel plating, liner seal surface roughness of 20, but there should be no obvious radial grooves and Nicks. Pressure type vacuum quick-release flange: pressure type vacuum quick-release flange is suitable for low, medium and high vacuum pipeline, sealed with O-type rubber seal ring. The connecting disc of this structure is made of carbon steel or stainless steel. If carbon steel is used, the surface needs nickel plating. The sealing roughness of the connecting disc shall be 20 and shall not have obvious radial grooves and Nicks. The concrete structure can be seen in GB4982-85.
