Q41N法兰高压球阀它具有旋转90度的动作，旋塞体为球体，有圆形通孔或通道通过其轴线。球阀在管路中主要用来做切断、分配和改变介质的流动方向，它只需要用旋转90度的操作和很小的转动力矩就能关闭严密。球阀适宜做开关、切断阀使用，但近来的发展已将球阀设计成使它具有节流和控制流量之用，如V型球阀。

 Q41N法兰高压球阀是通过螺栓连接主副体，本身结构紧凑，密封度好，外形美观，维修方便，密封面与球面常在闭合状态，不易被介质冲蚀，易于操作和维修，适用于水、溶剂、酸和天然气等一般工作介质，而且还适用于工作条件恶劣的介质，如氧气、过氧化氢、甲烷和乙烯等，在各行业得到广泛的应用。球阀阀体可以是整体的，也可以是组合式的。

Q41N法兰高压球阀优点：

       1．流体阻力小，全通径的球阀基本没有流阻。

       2．结构简单、体积小、重量轻。

       3．紧密稳定。它有两个密封面，而且目前球阀的密封面材料广泛使用各种塑料，密封性好，能实现完全密封。在真空系统中也已广泛使用。

       4．操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。

       5．维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。

       6．在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。

       7．适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。

       8．由于球阀在启闭过程中有擦拭性，所以可用于带悬浮固体颗粒的介质中。

法兰高压球阀

法兰高压球阀是一种用于高压流体控制的阀门，采用法兰连接方式，适用于石油、化工、天然气等高压管道系统。

法兰高压球阀- 结构组成：通常由阀体、阀盖、阀座、球体、阀杆、支架和传动装置等组成。主体部件多采用锻造或轧制工艺成型，左右两阀盖通过螺栓固定在阀体两侧，之间装有密封圈，阀座上设有球体，球芯上端连接阀杆，阀杆外圆面与阀体间有填料，上方有填料压紧装置，阀杆顶部是传动装置。

法兰高压球阀- 工作原理：通过传动装置在阀杆顶部施加转矩，带动球体旋转90°，使球芯的通孔与阀体通道中心线重合或垂直，从而实现阀门的全开或全关，控制介质流通或截断。

法兰高压球阀- 性能特点：具有承压能力强的特点，能承受较高压力和温度；密封稳定，采用密封技术，可有效防止泄漏；操作简便，启闭迅速，只需旋转90°即可完成操作，且便于远程控制；流体阻力小，全通径球阀开启时，流体通道畅通，适合高流量介质输送；结构紧凑，体积小、重量轻，便于安装和维修，密封圈多为活动式，更换方便；部分球阀还具备密封面自清洁功能，可冲走密封面上的聚积物。

法兰高压球阀- 适用范围：适用介质广泛，包括水、油、气、蒸汽、硝酸、醋酸等。工作温度范围通常在-40℃至350℃之间，公称压力一般为6.4MPa至42MPa，特殊情况可定制更高压力。

The flanged high - pressure ball valve is a kind of valve used for high - pressure fluid control. It adopts the flanged connection mode is suitable for high - pressure pipeline systems such as petroleum, chemical industry, natural gas. The product overview is as follows:

- Structural composition: It is usually composed of valve body, valve cover, valve seat, ball, valve stem, support transmission device, etc. The main components are mostly formed by forging rolling processes. The left right valve covers are fixed on both sides of the valve body by bolts, with a sealing ring installed between them. The valve seat is provided with a ball, the upper end of the ball core is connected to the valve stem. There is packing between the outer cylindrical surface of the valve stem the valve body, a packing pressing device is arranged above it. The top of the valve stem is the transmission device.

- Working principle: Torque is applied to the top of the valve stem through the transmission device, driving the ball to rotate 90 °, so that the through - hole of the ball core coincides with is perpendicular to the central line of the valve body channel, thus realizing the full - open full - closed state of the valve to control the flow cut - off of the medium.

- Performance characteristics: It has the characteristic of strong pressure - bearing capacity can withstand high pressure temperature. The sealing is reliable. Advanced sealing technology is adopted to effectively prevent leakage. It is easy to operate, the opening closing are rapid. Only a 90 ° rotation is required to complete the operation, it is convenient for remote control. The fluid resistance is small. When the full - bore ball valve is opened, the fluid channel is unobstructed, which is suitable for the transportation of high - flow media. The structure is compact, with a small volume light weight, which is convenient for installation maintenance. Most of the sealing rings are movable, making replacement convenient. Some ball valves also have the self - cleaning function of the sealing surface, which can wash away the deposits on the sealing surface.

- Scope of application: It is suitable for a wide range of media, including water, oil, gas, steam, nitric acid, acetic acid, etc. The working temperature range is usually between - 40℃ 350℃, the nominal pressure is generally between 6.4MPa 42MPa. Higher pressure can be customized in special cases.
