字壓力表、攝氏度作為能源驅(qū)動(dòng)閥門自動(dòng)工作，不需要外接電源和二次儀表。這種自力式調(diào)節(jié)閥都利用閥輸出端的反饋信號(hào)源（數(shù)字壓力表、壓差、攝氏度）通過(guò)信號(hào)源管傳遞到運(yùn)行組織驅(qū)動(dòng)閥瓣改變閥門的開(kāi)度，達(dá)到調(diào)節(jié)數(shù)字壓力表、流量、攝氏度的目的。這種調(diào)節(jié)閥又分為直接功用式和間接功用式兩種。

直接功用自力式調(diào)節(jié)閥又稱為彈簧負(fù)載式，其結(jié)構(gòu)內(nèi)有彈性元件如：彈簧、波紋管、波紋管式的溫包等，利用彈性力與反饋信號(hào)源平衡的原理。?如果是數(shù)字壓力表自力式調(diào)節(jié)閥，反饋信號(hào)源就是閥的出口數(shù)字壓力表，通過(guò)信號(hào)源管引入運(yùn)行組織。?如果是流量自力式調(diào)節(jié)閥，閥的出口處就有一個(gè)孔板（或者是其他阻力裝置）由孔板兩端取出壓差信號(hào)源引入運(yùn)行組織。?如果是攝氏度自力式調(diào)節(jié)閥，閥的出口就有攝氏度傳感器（或者溫包）通過(guò)攝氏度傳感器內(nèi)介質(zhì)的熱脹冷縮驅(qū)動(dòng)運(yùn)行組織。(1)?取壓點(diǎn)應(yīng)取在調(diào)壓閥適當(dāng)位置，閥前調(diào)壓應(yīng)大于2倍管道直徑，閥后調(diào)壓應(yīng)大于6倍管道直徑。

(2)?自力式閥根據(jù)計(jì)算通徑可以小于管道直徑，而截止閥、切斷球閥、旁通閥、過(guò)濾器則不能小于管道直徑。
