【進口氣動薄膜三通調(diào)節(jié)閥】詳細說明:
氣動三通調(diào)節(jié)閥有合流和分流兩種結(jié)構(gòu)形式。其組成結(jié)構(gòu)由多彈簧氣動薄膜執(zhí)行機構(gòu)和采用圓筒型薄壁窗口型閥芯的三通合流(分流)閥組成。其組成結(jié)構(gòu)由多彈簧氣動薄膜執(zhí)行機構(gòu)和采用圓筒型薄壁窗口型閥芯的三通合流(分流)閥組成,并結(jié)合國內(nèi)應有對氣動三通調(diào)節(jié)閥的技術(shù)。成功開發(fā)出新一代的氣動三通調(diào)節(jié)閥。氣動三通調(diào)節(jié)閥其閥芯結(jié)構(gòu)采用圓筒薄壁窗口,并采用閥芯側(cè)面導向,閥體為三通結(jié)構(gòu),即一進兩出(分流型),兩進一出(合流型),從而達到流體混合升溫或降溫,或流體不等量分流,滿足不同工礦的使用要求。該氣動三通調(diào)節(jié)閥具有結(jié)構(gòu)緊湊、重量輕、動作靈敏、壓降損失小、閥容量大、流量特性精確和安裝維修簡便等優(yōu)點。
Pneumatic three-way regulating valve has two types of structure: confluence and diversion. The structure consists of a multi-spring pneumatic film actuator and a three-way confluence (shunt) valve with a cylindrical thin-walled window core. The structure consists of a multi-spring pneumatic membrane actuator and a three-way confluence (diversion) valve with a cylindrical thin-walled window spool. The technology of pneumatic three-way regulating valve should be combined with domestic technology. A new generation of pneumatic three-way regulating valve has been successfully developed. Pneumatic three-way regulating valve adopts thin-walled cylindrical window and side-oriented spool. The valve body is three-way structure, i.e. one-in-two-out (diversion type) and two-in-one-out (confluence type), so as to meet the requirements of different industries and mines for mixing, heating or cooling of fluids, or unequal diversion of fluids. The pneumatic three-way regulating valve has the advantages of compact structure, light weight, sensitive action, low pressure drop loss, large valve capacity, accurate flow characteristics and simple installation and maintenance.
【進口氣動薄膜三通調(diào)節(jié)閥】結(jié)構(gòu)特點:
三通閥有三個出入口與管道相連,相當于兩臺單座閥合成一體。 按作用分為合流閥(兩進一通)與分流閥(一進兩通)。 工作時,一路全開,一路全關(guān),所以關(guān)閉時受力與單座閥相似,不平衡力大。 三通閥閥芯與套筒閥的套筒一樣,其截留面積有開大窗和打小孔(噴射型)兩種,后者有降低噪音,減小共振的功能。按作用方式分為三通合流調(diào)節(jié)閥和三通分流調(diào)節(jié)閥兩種。合流調(diào)節(jié)閥是兩種流體通過閥加以混合,例如兩種不同溫度的流體通過閥混合溫度介于前兩者之間的流體。這種閥有兩個進口和一個出口。分流調(diào)節(jié)閥是把一種流體通過閥后分成兩路,當閥在關(guān)閉一個出口的同時就打開了另一個出口,這種閥有一個入口和兩個出口。 但其合流調(diào)節(jié)閥和分流調(diào)節(jié)閥芯位置不一樣,合流調(diào)節(jié)閥的閥芯位于兩閥座之內(nèi),分流閥的閥芯位于兩閥座之外,這樣設計閥芯,可以使流動方向?qū)㈤y芯處于流開狀態(tài),合流調(diào)節(jié)閥能穩(wěn)定操作。所以,一般而言,合流調(diào)節(jié)閥應用于合流的場合,分流調(diào)節(jié)閥應用于分流的場合
