Класификация на хидравличните фитинги

Видове хидравлични фитинги

NPTF конусна резбапринадлежности

Описание: Това е резба за сухо уплътнение; Това е домашна конусна тръбна резба за пренос на мазут. Може да се използва както за края на външната резбапринадлежности и край на вътрешната резбапринадлежности. NPTF external threads can be fitted with NPTF, NPSF or NPSM internal threads. NPTF fittings are similar to BSPT fittings but not interchangeable. Most sizes of threads have different pitch and profile Angle of 60°, whereas BSPT threads have profile Angle of 55°.

JIC37°taper Angle internal threadпринадлежности

Description: 37°Cone Angle (JIC) The Society of Automotive Engineers (SAE) specifies that 37°cone Angle or cone holder can be used for high pressure hydraulic pipelines. This type ofпринадлежностичесто се нарича JICfittings or JIC adapter. JIC external thread is straight thread can only be matched with JIC internal thread, JIC external thread is straight thread, and has a 37°cone seat surface, JIC internal thread is straight thread, and has a 37°cone seat surface. The seal is formed at the 37°cone seat surface. Some sizes of thread are the same as SAE45°cone thread. The cone Angle should be carefully measured to distinguish.

SAE 45°taper male thread adapter

Description: SAE(45°Cone Angle) This is the term used for pipeпринадлежности с 45°cone Angle or cone seat. Soft copper pipes usually use this принадлежности because the material can be easily machined to a 45°Angle. Thisпринадлежности is suitable for low pressure applications such as fuel lines and refrigeration lines. SAE 45°taper external thread can only be matched with SAE 45°taper internal thread. SAE external threads are straight threads with 45°taper seat. SAE internal threads are also straight threads and have a 45°taper mount. The seal is formed at the 45°cone seat surface. Some sizes of thread are the same as SEA 37°taper thread. The cone Angle should be carefully measured for zone running.

О-пръстен, уплътняващ външната резба на крайната повърхностпринадлежности

Забележка: Външната резба на крайното уплътнение на О-пръстена може да се съчетае само с вътрешната резба на крайното уплътнение на О-пръстена, външната резба е права резба с О-пръстен; Вътрешната резба е права резба с уплътнителна крайна повърхност, външната резба е запечатана в О-пръстена, а вътрешната резба е запечатана в уплътнителната крайна повърхност.

O-ring plane seal fixed external thread принадлежности

Note: When the o-ring on the outer thread принадлежности is in contact with the plane on the inner threadпринадлежности to form a seal, the elastomer seal can be used in the hydraulic system to control leakage, and in the case of leak proof function is very important, this kind of pipeпринадлежности може да се използва.

pressure sleeve type pipe joint

Note: Pressure sleeve type fixed external threadпринадлежности can only be matched with pressure sleeve type internal thread nut and pressure sleeve. External connection is straight thread with 24°taper seat. The inner thread head is straight thread with pressure sleeve as sealing face. The seal is formed between the pressure sleeve and the 24°cone seat of the external thread joint, and between the pressure sleeve and the inner pipe of the internal threadпринадлежности.
