焊接角式截止阀

焊接角式截止阀是一种采用焊接连接和角式流道（进口与出口成90°直角）的截止阀。它结合了角式阀门的流路优势与焊接连接的密封稳定性，专为要求完全无泄漏、连接的高压、高温、高危或禁忌法兰连接的苛刻工况而设计。

焊接角式截止阀其核心设计特点和关键技术包括：

焊接端连接 (Welded End Connection): 阀体两端加工有坡口，通过对焊（Butt Welding, BW） 或承插焊（Socket Welding, SW） 的方式与管道连接。这种连接方式提供了极高的密封完整性，彻底杜绝了法兰连接可能存在的界面泄漏风险，同时增强了连接处的结构强度和抗疲劳性。

焊接角式截止阀角式流道设计 (Angular Flow Path Design): 进口与出口管道成90°直角。这种设计允许流体实现自然的90°方向改变，能有效降低流阻，减少对阀内件的直接冲刷。它可以直接安装在管道的弯头位置，节省安装空间和管件，简化管道布局。

密封与截止功能 (Sealing & Shut-off Function): 阀瓣（Disc）通常为锥形或平顶设计，与阀座（Seat）形成紧密的线密封或面密封。当阀门关闭时，能实现严密稳定的切断，确保介质零泄漏。其流道设计使得阀座在高压差下承受的冲刷力小于直通式截止阀，延长了密封面的使用寿命。

焊接角式截止阀适用苛刻工况: 由于没有法兰连接所需的垫片，焊接连接避免了因垫片老化、腐蚀或不适配而导致的泄漏问题，使其特别焊接角式截止阀适用于：

高温高压蒸汽系统

剧毒、易燃易爆或放射性介质管道

要求高纯净度的管道（如核电、洁净工艺）

地下或不易接近、需免维护的场所

焊接角式截止阀应用领域:

广泛应用于石油化工、电力（特别是火电和核电）、核工业、供热系统、以及各类要求密封的高压高温工业管道中。

焊接角式截止阀核心价值:

提供了所有连接方式中最高等级的密封性和结构完整性，是一种为极端工况设计的“一劳永逸”的切断解决方案，以其卓越的密封性和长寿命保障关键系统的安全。

Product Name: Welded Angle Globe Valve

Product Overview:

The Welded Angle Globe Valve is a type of globe valve that utilizes welded end connections an angular flow path (inlet outlet are oriented at a 90-degree angle). It combines the flow path advantages of an angle valve with the sealing reliability of welded connections. It is specifically designed for demanding services that require absolute leak-proof, permanent connections under high pressure, high temperature, hazardous conditions, flanged connections are prohibited.

Its core design features key technologies include:

Welded End Connection: The valve ends are prepared with bevels for permanent connection to the pipeline via Butt Welding (BW) Socket Welding (SW). This connection method provides the highest level of sealing integrity,彻底 eliminating the potential for leakage at connection interfaces inherent to flanged joints. It also enhances the structural strength fatigue resistance at the connection point.

Angular Flow Path Design: The inlet outlet are at a 90-degree right angle. This design allows for a natural 90-degree change in fluid direction, effectively reducing flow resistance minimizing direct impingement on the valve trim. It can be installed directly at a pipeline elbow, saving installation space pipe fittings, thereby simplifying piping layout.

Sealing & Shut-off Function: The disc is typically tapered flat-faced, forming a tight line face seal with the seat. When closed, the valve achieves tight reliable shut-off, ensuring zero leakage of the medium. The flow path design subjects the seat to less erosive force under high pressure differentials compared to straight-through globe valves, extending the service life of the sealing surfaces.

Suitability for Demanding Services: The absence of gaskets required for flanged connections eliminates leakage risks associated with gasket aging, corrosion, incompatibility. This makes it particularly suitable for:

High-temperature high-pressure steam systems

Piping handling highly toxic, flammable, explosive, radioactive media

Piping requiring high purity (e.g., nuclear power, clean processes)

Underground hard-to-access locations requiring maintenance-free operation

Applications:

Widely used in petrochemical, power generation (especially thermal nuclear power), nuclear industry, heating systems, various high-pressure & high-temperature industrial pipelines requiring permanent sealing.

Core Value:

It provides the highest level of sealing integrity structural strength among all connection types. It is a "fit--forget" reliable shut-off solution designed for extreme conditions, ensuring the safety of critical systems through its superior leak-tightness long service life.
