進口小口徑單座調節(jié)閥(德國奧萊斯OLES閥門品牌)
【進口小口徑單座調節(jié)閥】詳細說明：
氣動調節(jié)閥單座調節(jié)閥閥體，適用于對泄露量要求嚴格、閥前后壓差低及有一定粘度和含少量纖維介質的場合。氣動流量調節(jié)閥,按照開關方式的不同可分為常開氣關式和常閉氣開式兩種。氣關式閥由正作用執(zhí)行機構和調節(jié)閥閥體組成。當輸入信號壓力由下限值改變?yōu)樯舷拗禃r，閥從全開到全關。氣開式閥由反作用執(zhí)行機構和調節(jié)閥閥體組成，當輸入信號壓力由下限值改變?yōu)樯舷拗禃r，閥從全關到全開。精小型氣動調節(jié)閥是以壓縮空氣為動力源，以氣動薄膜式或者氣動活塞式為執(zhí)行機構，選配電氣閥門定位器、電氣轉換器、電磁閥、保位閥等附件來實現(xiàn)開關量或比例式調節(jié)，接收工業(yè)自動化控制系統(tǒng)的控制信號來完成管道介質的：流量、壓力、溫度等各種工藝參數(shù)的控制。
Pneumatic control valve single seat control valve body, suitable for strict leakage requirements, low pressure difference before and after the valve, with a certain viscosity and a small amount of fiber medium occasions. Pneumatic flow control valves can be divided into two types according to the different switching modes: normal opening and normal closing. The air-closed valve is composed of a positive actuator and a regulating valve body. When the input signal pressure changes from the lower limit to the upper limit, the valve is fully open to fully close. The air-opened valve is composed of reaction actuator and control valve body. When the input signal pressure changes from lower limit to upper limit, the valve closes completely to open completely. Fine and small pneumatic control valves use compressed air as power source, pneumatic thin film or pneumatic piston as actuator, select and distribute pneumatic valve positioner, electrical converter, solenoid valve, holding valve and other accessories to realize switching or proportional regulation, and receive control signals of industrial automation control system to complete pipeline introduction. Quality: Flow, pressure, temperature and other process parameters control.
【進口小口徑單座調節(jié)閥】特點：
1、控制簡單，反應快速，且本質安全，無需另外再采取防爆措施；
2、執(zhí)行機構采用精小型多彈簧結構，實現(xiàn)了小型化，輕型化，對空間的有效利用作出了貢獻；
3、標準化部件設計；互換性強，減少了用戶的庫存量，降低了使用成本，大大提高了性價比。
【進口小口徑單座調節(jié)閥】特性：
氣動薄膜單座調節(jié)閥/電子式電動單座調節(jié)閥，由單座閥體與氣動、電子式或電動執(zhí)行機構組成。精小型單座調節(jié)閥閥體結構緊湊、重量輕、動作靈敏、流體通道呈S流線型、壓降損失小、閥容量大、流量特性精確、拆裝方便等優(yōu)點。廣泛應用于精確控制氣體、液體、蒸汽等介質，工藝參數(shù)如壓力、流量、溫度、液位保持在給定值。特別適用于允許泄漏量小閥前后壓差不大的工作場合。
若閥門可能產(chǎn)生空化、汽蝕，建議選用套筒調節(jié)閥；
若閥門可能產(chǎn)生閃蒸，建議選用縮腔型，閥芯及閥座堆焊硬質合金。
波紋管密封型對上下移動的閥桿形成*的密封,堵絕流體外漏
低溫型采用長頸閥蓋加波紋管封密結構可用于-196℃的深冷場合
調節(jié)切斷型軟密封結構閥芯達VI級泄漏標準(微氣泡級)
夾套保溫型帶用不銹鋼保溫夾套,用于流體冷卻后易結晶凝固造成堵塞的場合
襯塑單座調節(jié)閥與流體接觸部位襯有F46,填料部位采用聚四氟乙烯波紋管密封,特別適用于強腐蝕介質的自動控制.
