三通抗生素截止閥，不銹鋼三通 截 止閥

三通抗生素截止閥是關(guān)閉件（閥瓣）沿閥座中心線(xiàn)移動(dòng)的閥門(mén)。
在管路中主要作切斷用。截止閥有以下優(yōu)點(diǎn)：

1．  在開(kāi)閉過(guò)程中密封面的摩擦力比閘閥小，耐磨。

2．  開(kāi)啟高度小。

3．  通常只有一個(gè)密封面，制造工藝好，便于維修。

三通抗生素截止閥使用較為普遍，但由于開(kāi)閉力矩較大，結(jié)構(gòu)長(zhǎng)度較長(zhǎng)，一般公稱(chēng)通徑都限制在DN≤200mm以下。

截止閥的流體阻力損失較大。因而限制了截止閥更廣泛的使用。

截止閥的種類(lèi)很多，根據(jù)閥桿上螺紋的位置可分：

截止閥閥桿的螺紋在閥體的外面。其優(yōu)點(diǎn)是閥桿不受介質(zhì)侵蝕，便于潤(rùn)滑，此種結(jié)構(gòu)采用比較普遍。

截止閥閥桿的螺紋在閥體內(nèi)。這種結(jié)構(gòu)閥桿螺紋與介質(zhì)直接接觸，易受侵蝕，并無(wú)法潤(rùn)滑。此種結(jié)構(gòu)用于小口徑和溫度不高的地方。

根據(jù)截止閥的通道方向，又可分為；直通式截止閥，角式截止閥和三通式截止閥，后兩種截止閥通常做改變介質(zhì)流向和分配介質(zhì)用。

The three-way antibiotic stop valve is a valve in which the closing part (disc) moves along the center line of the valve seat.

The three-way antibiotic stop valve is mainly used for cutting off in the pipeline. The globe valve has the following advantages:

   1. In the process of opening and closing, the friction of the sealing surface is smaller than that of the gate valve, and it is wear-resistant.

   2. The opening height is small.

   3. Usually there is only one sealing surface, the manufacturing process is good, and the maintenance is easy.

The three-way antibiotic stop valve is commonly used, but due to the large opening and closing torque and the long structure length, the general nominal diameter is limited to DN≤200mm.

The fluid resistance loss of the shut-off valve is relatively large. This limits the wider use of the shut-off valve.

   There are many types of shut-off valves, which can be divided according to the position of the thread on the stem:

   1. Three-way antibiotic stop valve The thread of the stop valve stem is on the outside of the valve body. The advantage is that the valve stem is not corroded by the medium and is convenient for lubrication. This kind of structure is more common.

   2. Three-way antibiotic stop valve The thread of the valve stem of the stop valve is in the valve body. The stem thread of this structure is in direct contact with the medium, which is susceptible to corrosion and cannot be lubricated. This structure is used in places with small diameters and low temperatures.

   According to the channel direction of the stop valve, it can be divided into: straight-through stop valve, angle stop valve and three-way stop valve. The latter two stop valves are usually used to change the flow direction of the medium and distribute the medium.
