1 . DPM/DPG/MC/MJ型抵抗式計(jì)量件又稱比例接頭。
2 .管式結(jié)構(gòu)，內(nèi)設(shè)有限流桿和單向閥。
3 .開啟壓力：0 . 2 M P a。
4 .通過節(jié)流原理控制流量，按流通能力（流量定數(shù)）對(duì)流量進(jìn)行比例分配。同型號(hào)計(jì)量件再潤(rùn)滑系統(tǒng)中相互間距離的遠(yuǎn)、近、高、低、臥裝或立裝均在實(shí)際使用中其出油量基本相同等。使用壽命長(zhǎng)，比例接頭單向閥其橡膠密封件外部試壓銅套（除密封面外）防止橡膠密封件膨脹和老化。
5 .動(dòng)作靈敏,排油暢通:比例接頭單向閥采用錐形彈簧,確保計(jì)量件動(dòng)作敏與排油暢通,并防止排除的油劑逆流。
6 .流量比：同一型號(hào)的流量在實(shí)際使用過程中會(huì)有環(huán)境溫度的變化和油的粘度不同而發(fā)生化。
1.DPM/DPG/MC/MJ type resistance measuring parts are also called proportional joints.
2. Tubular structure with restrictor rod and check valve.
3. Opening pressure: 0.2MPa
4. Control the flow through the throttling principle and distribute the flow proportionay according to the flow capacity (flow number). The far,near, high, low, horizontal or vertical installations in the relubrication system of the same type of metering component are all basically the samein actual use. Long service life, the proportion of joints check valve rubber seal external pressure test copper sleeve (except the sealing surface) to prevent rubber seals from swelling and aging.
5. Sensitive operation and smooth oil discharge: The proportional joint check valve adopts conical spring to ensure that the metering part is sensitive and oil-free and prevents the excluded oil agent from flowing backwards.
6. Flow ratio: The flow of the same model will change with the change of the ambient temperature and the viscosity of the oil during the actual use.
