今天小编主要通过这篇文章跟大家讲解下钢制卡套接头的结构原理：钢制卡套接头它是用来控制微量调节的一个小型阀门。一般通径分为两种15 mm和10 mm。密封性是取决于锥形丝扣阀芯体和阀座密封圈的紧密吻合而决定的。针型阀所使用的材质一般是由合金钢构成的，但也有使用铜合金制作阀头的密封圈。所以，在使用针型阀之前。应当拆开检查阀头和阀座的材质。
Today small make up mainly through this article to explain the structural principle of the steel bayonet joint: steel bayonet joint is used to control the micro-adjustment of a small valve. The general diameters are divided into two types: 15 mm and 10 mm. Sealing is determined by the close fit of the conical thread spool and the seat sealing ring. Needle valve material used is generally made of alloy steel, but there is also the use of copper alloy valve head sealing ring. So, before using the needle valve. The head and seat material should be disassembled for inspection.
为了防止使用过程中掉头或者出现磨损的现象。在发酵生产过程中，较多地使用不锈钢针型阀，对保证严密度起到一定的作用。卡套式接头良好的切断性能。拥有的一个最大特点就是球面阀芯与阀座斜面之间的接触采用的是线接触的形式，从而降低了接触面，能更进一步的降低了阀门的泄漏率。
In order to prevent the use of the u-turn or the phenomenon of wear and tear. In the fermentation production process, more use of stainless steel needle valve, to ensure the rigor has a certain role. Good cutting performance of bayonet joint. One of the biggest features is that the contact between the spherical spool and the seat slant is in the form of linear contact, thus reducing the contact surface, can further reduce the leakage rate of the valve.

江门艾瑞vcr接头生产厂家生产的vcr接头产品质量真的很好，已经合作过2年了。
公司需要316不锈钢材质的vcr接头，刚好遇到了艾瑞精密机械科技有限公司，其能够生产316材质的vcr接头，满足了公司的需求。
vcr接头的厂家在国内真的很少，一直合作的就是艾瑞精密机械科技有限公司了，公司生产的产品符合我司的要求。
跟很多家vcr接头贸易商合作过，但是自从跟艾瑞vcr接头生产厂家合作过就一直觉得比其他贸易商好，可以看到产品的质量差别。
