Electric precision and small two-seat regulating valve adopts double-guide structure with electronic direct-stroke electric actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics, convenient disassembly and assembly, etc. It is widely used to precisely control the process parameters of gas, liquid, steam and other media, such as pressure, flow, etc. Temperature and liquid level should be kept at a given value. It is especially suitable for medium occasions with large pressure difference, large allowable leakage and not very clean. Products include standard type, bellows sealing type, jacket insulation type and other varieties. The nominal pressure grades of products are PN16, 40, 64; the nominal diameter range is DN25-400. The applicable fluid temperature is -250 ~560 C. Various grades within the scope. Leakage standard is level II or IV. Flow characteristics are linear or equal percentage. Various specifications are available.
【進(jìn)口電動(dòng)精小型調(diào)節(jié)閥】工作原理：
精小型電動(dòng)調(diào)節(jié)閥與被調(diào)介質(zhì)直接接觸，由于閥芯運(yùn)動(dòng)，改變了閥芯與閥座間的流通面積，即改變了閥的阻力系數(shù)，從而改變了流經(jīng)調(diào)節(jié)機(jī)構(gòu)介質(zhì)的流量，達(dá)到了對(duì)工藝參數(shù)的調(diào)節(jié)。精小型電動(dòng)調(diào)節(jié)閥是由智能型電子式電動(dòng)執(zhí)行器通過支架與單座、套筒調(diào)節(jié)閥連接在一起所 組成。當(dāng)輸入端無信號(hào)時(shí)，執(zhí)行器穩(wěn)定在預(yù)選的零位，調(diào)節(jié)閥處于全開或全閉的位置，執(zhí)行器的輸出軸通過開合螺 母與調(diào)節(jié)閥的閥桿相連。當(dāng)輸入端有信號(hào)時(shí)輸出軸即通過輸入信號(hào)按一定比例處在一定的位置，調(diào)節(jié)閥即處于所需開度，從而達(dá)到了調(diào)節(jié)和控制的目的。精小型電動(dòng)調(diào)節(jié)閥分為電開式和電閉式兩種。通過選擇電子式電動(dòng)執(zhí)行器的正、反 作用開關(guān)來實(shí)現(xiàn)電開式和電閉式調(diào)節(jié)。
【進(jìn)口電動(dòng)精小型調(diào)節(jié)閥】特點(diǎn)：
1、控制簡單，反應(yīng)快速，且本質(zhì)安全，無需另外再采取防爆措施；
2、執(zhí)行機(jī)構(gòu)采用精小型多彈簧結(jié)構(gòu)，實(shí)現(xiàn)了小型化，輕型化，對(duì)空間的有效利用作出了貢獻(xiàn)；
3、標(biāo)準(zhǔn)化部件設(shè)計(jì)；互換性強(qiáng)，減少了用戶的庫存量，降低了使用成本，大大提高了性價(jià)比。
