真空卡盘球阀

进口真空球阀

德国进口真空(压力)球阀是适用于真空（是指工作压力低于标准大气压的，形成一定真空的气体）系统中接通或切断管路的介质流。该阀为直通式手动球阀，靠球面密封，因而既能用在真空状态下，也能在低压状态下使用，并可任意位置安装。 适用的工作介质真空气体。应用于真空、乳制品、酒业、生物工程、食品、制药、饮料、化妆品及化工领域。

Germany imported vacuum (pressure) is applied to the vacuum valve (refer to the working pressure is lower than the standard atmospheric pressure, a certain vacuum gas) system is turned on or off medium flow pipeline. The manual ball valve for straight-through, by spherical seal, which can not only be used in a vacuum, can be used at low pressure, and can be installed anywhere. Suitable working medium vacuum gas. Vacuum is applied, dairy products, wine, biological engineering, food, pharmaceutical, beverages, cosmetics and chemical industries.

进口真空球阀连接形式：

法兰连接可分为以下几种：

1）光滑式：用于压力不高的阀门。加工比较方便

2）凹凸式：工作压力较高，可使用中硬垫圈

3）榫槽式：可用塑性变形非常大的垫圈，在腐蚀性介质中使用较广泛，密封效果较好。

4）梯形槽式：用椭圆形金属环作垫圈，使用于工作压力≥64公斤/平方厘米的阀门，或高温阀门。

5）透镜式：垫圈是透镜形状，用金属制作。用于工作压力≥100公斤/平方厘米的高压阀门，或高温阀门。

6）O形圈式：这是一种较新的法兰连接形式，它是随着各种橡胶O形圈的出现，而发展起来的，它在密封效果上比一般平垫圈可靠。

Imported vacuum valve connection:

Flange connections can be divided into the following categories:

1) Smooth formula: valves for pressure is not high. Processing more convenient

2) lenticular: higher working pressure, can be used in hard washer

3) tenon slot: available plastic deformation larger washers, use in corrosive media is more extensive and better seal.

4) trapezoidal trough: oval metal ring, gasket, the use of working pressure ≥64 kg / cm of the valve, or high temperature valves.

5) Lens type: washer lens shape, made of metal. For working pressure ≥100 kg / cm high pressure valves, or high temperature valves.

6) O-ring style: This is a relatively new form of flange connection, it is with the emergence of a variety of rubber O-ring, and developed, it is generally flat washers reliable sealing effect on the ratio.

螺纹连接又可分为以下几种：

这是一种简便的连接方法，常用于小阀门。又分两种情况：

1）直接密封：内外螺纹直接起密封作用。为了确保连接处不漏，往往用铅油、线麻和聚四氟乙烯生料带填充；其中聚四氟乙烯生料带，使用日见广泛；这种材料耐腐蚀性能很好，密封效果较佳，使用和保存方便，拆卸时，可以完整地将其取下，因为它是一层无粘性的薄膜，比铅油、线麻优越得多。

2）间接密封：螺纹旋紧的力量，传递给两平面间的垫圈，让垫圈起密封作用。

快卸法兰(GB4982) 0.1×106～1.3×10-4

螺纹连接　Threaded Connection 1.6×106～1.3×10-4

Threaded connection can be divided into the following categories:

This is a simple connection method, commonly used in small valve. Was divided into two cases:

1) Direct Seal: internal and external thread directly from the seal. To ensure that the connection does not leak, often with lead oil, hemp and Teflon tape filled; which Teflon tape, has become increasingly widespread use; this material good corrosion resistance, sealing effect pole good, easy to use and preservation, demolition, you can completely remove it, because it is a layer of non-tacky film, hemp oil is much superior to the lead line.

2) Indirect Seal: Thread tighten force transmitted to the gasket between two planes, so that the gasket from sealing.

进口真空球阀特点：

1、可在高真空状态下使用，也可在低压的系统下使用，达到正负压同用的优点。

2、不仅结构简单、密封性好、而且安装尺寸小，驱动力矩小，操作简单，易实现快速启闭

Imported vacuum valve features:

1, can be used in a high vacuum, may also be used in low-pressure system to achieve the advantages with the use of positive and negative pressure.

2, is not only simple structure, good sealing, and the installation of small size, small drive torque, simple operation, easy open and close fast
