德國(guó)進(jìn)口真空(壓力)球閥是適用于真空（是指工作壓力低于標(biāo)準(zhǔn)大氣壓的，形成一定真空的氣體）系統(tǒng)中接通或切斷管路的介質(zhì)流。該閥為直通式手動(dòng)球閥，靠球面密封，因而既能用在真空狀態(tài)下，也能在低壓狀態(tài)下使用，并可任意位置安裝。 適用的工作介質(zhì)真空氣體。應(yīng)用于真空、乳制品、酒業(yè)、生物工程、食品、制藥、飲料、化妝品及化工領(lǐng)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.

進(jìn)口真空球閥連接形式：

法蘭連接可分為以下幾種：

1）光滑式：用于壓力不高的閥門(mén)。加工比較方便

2）凹凸式：工作壓力較高，可使用中硬墊圈

3）榫槽式：可用塑性變形較大的墊圈，在腐蝕性介質(zhì)中使用較廣泛，密封效果較好。

4）梯形槽式：用橢圓形金屬環(huán)作墊圈，使用于工作壓力≥64公斤/平方厘米的閥門(mén)，或高溫閥門(mén)。

5）透鏡式：墊圈是透鏡形狀，用金屬制作。用于工作壓力≥100公斤/平方厘米的高壓閥門(mén)，或高溫閥門(mén)。

6）O形圈式：這是一種較新的法蘭連接形式，它是隨著各種橡膠O形圈的出現(xiàn)，而發(fā)展起來(lái)的，它在密封效果上比一般平墊圈可靠。

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.

螺紋連接又可分為以下幾種：

這是一種簡(jiǎn)便的連接方法，常用于小閥門(mén)。又分兩種情況：

1）直接密封：內(nèi)外螺紋直接起密封作用。為了確保連接處不漏，往往用鉛油、線麻和聚四氟乙烯生料帶填充；其中聚四氟乙烯生料帶，使用日見(jiàn)廣泛；這種材料耐腐蝕性能很好，密封效果極佳，使用和保存方便，拆卸時(shí)，可以完整地將其取下，因?yàn)樗且粚訜o(wú)粘性的薄膜，比鉛油、線麻優(yōu)越得多。

2）間接密封：螺紋旋緊的力量，傳遞給兩平面間的墊圈，讓墊圈起密封作用。

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.
