四、進(jìn)口電動蒸汽調(diào)節(jié)閥工作原理：

進(jìn)口電動蒸汽調(diào)節(jié)閥由控制閥門、電動執(zhí)行機(jī)構(gòu)、溫度傳感器和溫度調(diào)節(jié)器等部件組成，根據(jù)用戶需要，分別有加熱型與冷卻型兩種結(jié)構(gòu)。加熱型調(diào)節(jié)閥的結(jié)構(gòu)與原理：工作前主閥芯處于半開位置，傳感器處于自然狀態(tài)。接上電源，主閥芯全開。介質(zhì)由箭頭方向流入主閥體、經(jīng)閥芯對儲熱箱進(jìn)行加熱。當(dāng)溫度升到相應(yīng)設(shè)定值時，傳感器即產(chǎn)生相應(yīng)線性信號輸入一體化執(zhí)行機(jī)構(gòu)，隨即驅(qū)動閥桿、閥芯產(chǎn)生位移，關(guān)閉主閥芯停止加熱。當(dāng)溫度低于設(shè)定值時，傳感器即產(chǎn)生線性信號輸入一體化執(zhí)行機(jī)構(gòu)，驅(qū)使閥芯漸開，使介質(zhì)按拋物線特性流入儲熱箱，進(jìn)行加熱直至設(shè)定值。這樣被控介質(zhì)始終在設(shè)定溫度范圍內(nèi)被控制，從而達(dá)到控溫目的。備注：常說的加熱型、冷卻型。在此閥中只要更換閥芯結(jié)構(gòu)即可以實現(xiàn)。

The imported electric steam regulating valve is composed of control valve, electric actuator, temperature sensor and temperature regulator. According to the needs of users, there are two types of structure: heating type and cooling type. Structure and principle of heating type regulating valve: before working, the main valve core is in half open position, and the sensor is in natural state. Connect the power supply and open the main valve core. The medium flows into the main valve body from the arrow direction and heats the heat storage tank through the valve core. When the temperature rises to the corresponding set value, the sensor will generate the corresponding linear signal, input the integrated actuator, and then drive the valve stem and spool to produce displacement, close the main valve core and stop heating. When the temperature is lower than the set value, the sensor generates a linear signal, which is input into the integrated actuator to drive the spool gradually open, so that the medium flows into the heat storage tank according to the parabolic characteristics, and heats up to the set value. In this way, the controlled medium is always controlled within the set temperature range, so as to achieve the purpose of temperature control. Remarks: heating type, cooling type. In this valve, it can be realized as long as the valve core structure is changed.
