氣動信號球閥  的詳細介紹

一、概述Outline:
氣動信號球閥主要用于截断或接通管路中的介质,亦可用用于流体的调节与控制,它与其它阀类相比,具有以下一些优点。

1、流體阻力小、球閥是所有閥類中流體阻力*小的一種,即使是縮徑球閥,其流體阻力也相當小。
2、止推軸承減小閥杆磨擦力矩,可使閥杆長期操作平穩靈活。
3、閥座密封性能好,采用聚四氟乙烯等彈性材料制成的密封圈,結構易于密封,而且球閥的閥封能力隨著介質壓力的增高而增大。
4、閥杆密封可靠,由于閥杆只作彷轉動運而不做升降運動,閥杆的填料密封不易破壞,且密封能力隨著介質的壓力增高而增大。
5、由于聚四氟乙烯等材料具有良好的自潤滑性,與球體的磨擦損失小,故球閥的使用壽命長。
6、下裝式閥杆和閥杆頭部凸階防止閥杆噴出,如火災造成閥杆密封破壞,凸階與閥體間還可形成金屬接觸,確保閥杆密封。
7、 防靜電功能:在球體、閥杆、閥體之間設置彈簧,能將開關過程産生的靜電導出。 執行機構

Pneumatic valve is mainly used for truncation or signal line connected to the media, can also be used for fluid regulation and control, it is compared with other valves, has the following advantages.

1, fluid resistance, ball valves in all a fluid path of least resistance, even reduced diameter valve, the fluid resistance is quite small.
2, stem thrust bearing reduces friction torque, smooth operation can stem the long-term flexibility.
3, the valve seat sealing performance, the use of PTFE seals and other flexible materials, structure easy to seal, and the ability with the ball valve closure increased with increasing media pressure.
4, valve stem seals and reliable, due to stem not only do the operation for turning down imitation of movement, stem packing seal is not easy to destroy, and the sealing ability increased with the increase of the pressure medium.
5, the PTFE and other materials with good self-lubrication, the friction loss with the ball, so the ball's long life.
6, download style stem and stem spray head convex order to prevent the stem, causing stem seal damage such as fire, convex order and the body can be formed between the metal contact, to ensure that the valve stem seals.
7, anti-static function: the ball, stem, between the valve spring set, static electricity generated by the switching process can export. Executive body.


采用新型系列GT型氣動執行器,有雙作用式和單作用式(彈簧複位),齒輪齒條傳動,安全可靠;大口徑閥門采用系列AW型氣動執行器拔叉式傳動,結構合理,輸出扭矩大,有雙作用式和單作用式。

1、齒輪式雙活塞,輸出力矩大,體積小。
2、氣缸選用鋁金材料,重量輕、外形美觀。
3、可在頂部、底部安裝手動操作機構。
4、齒條式連接可調節開啓角度、額定流量。
5、執行器可選帶電訊號反饋指示及各類附件以實現自動化操作。
6、IS05211標准連接爲宅男吧的安裝更換提供了方便。
7、兩端調的節螺釘可使標准宅男吧在0°和90°有±4°的可調範圍。確保與閥門的同步精度。 

附件的選項 
根據不同控制和要求可選擇下列附件:
切斷型附件:單電控電磁閥、雙電控電磁閥、限位開關回訊器。
調節型附件:電氣定位器、氣動定位器、電氣轉換器。
氣源處理附件:空氣過濾減壓閥、氣源處理三聯件。
手動機構:HVSD手操機構 
 

Using the new series of GT type pneumatic actuator, a double-acting and single acting (spring return), rack and pinion drive, safe and reliable; AW series of large diameter valves using pneumatic actuator fork-type transmission, reasonable structure, output torque, a double-acting and single acting.

1, dual-piston gear, the output torque, small size.
2, cylinder aluminum alloy materials used, light weight, beautiful appearance.
3, can be at the top, the bottom of the installation manual operating mechanism.
4, the rack can be adjusted opening angle connection, the rated flow.
5, optional electric actuator feedback signal instructions and all kinds of accessories in order to achieve automation.
6, IS05211 standard connection for the installation of the product provides a convenient replacement.
7, both ends of the section of the screw can adjust the standard products in the 0 ° and 90 ° with ± 4 ° of adjustable range. Ensure the accuracy of synchronization with the valve.

Attachment options
Control and can choose according to different requirements of the following accessories:
Cut-off accessories: single electric solenoid valve, double solenoid valve, limit switch back to the hearing.
Regulated accessories: electrical positioner, pneumatic positioners, electric converter.
Air treatment accessories: air filter regulator, air source treatment FRL.
Manual institutions: HVSD HART agencies
