style="text-indent:25px">單向閥閥芯的固定結(jié)構(gòu)，包括閥體、設(shè)置在閥體內(nèi)的閥芯以及閥芯下方用于頂?shù)珠y芯的彈簧、以及彈簧下方用于對(duì)彈簧進(jìn)行限位的彈簧座，其特征在于，閥體的內(nèi)部向內(nèi)凸設(shè)有多個(gè)連接柱，用于通過連接件將彈簧座與閥體的下端連接固定。單向閥閥芯的固定結(jié)構(gòu)與閥體是可拆卸連接，可以方便拆卸和安裝，方便于單向閥使用后期的維護(hù)和維修；并且可以在單向閥通氣時(shí)和在單向閥不工作時(shí)，有效的對(duì)閥芯進(jìn)行限位固定，閥芯不會(huì)左右搖擺，可以在彈簧復(fù)位時(shí)使閥頭與密封圈準(zhǔn)確復(fù)位接觸，從而避免了現(xiàn)有的單向閥在彈簧復(fù)位時(shí)由于閥芯搖擺而與密封圈接觸出現(xiàn)傾斜、錯(cuò)位導(dǎo)致密封不嚴(yán)緊、單向閥損壞的缺陷。</p><p style="text-indent:25px">閥芯可將閥前管路較高的水壓減少至閥后管路所需的水平。閥芯普遍用于高層建筑、城市給水管網(wǎng)水壓過高的區(qū)域、礦井及其他場(chǎng)合，以保證給水系統(tǒng)中各用水點(diǎn)獲得適當(dāng)?shù)姆?wù)水壓和流量。鑒于水的漏失率和浪費(fèi)程度幾乎同給水系統(tǒng)的水壓大小成正比，因此閥芯具有改善系統(tǒng)運(yùn)行工況和潛在節(jié)水作用，據(jù)統(tǒng)計(jì)其節(jié)水效果約為30％。閥芯是氣動(dòng)調(diào)節(jié)的一個(gè)必備配件，主要作用是將氣源的壓力減壓并穩(wěn)定到一個(gè)定值，以便于調(diào)節(jié)閥能夠獲得穩(wěn)定的氣源動(dòng)力用于調(diào)節(jié)控制。閥芯是一種自動(dòng)降低管路工作壓力的專門裝置。</p><div
