進(jìn)口低壓背壓閥德國洛克《DE LOCKE》廠家強(qiáng)烈推薦

一、進(jìn)口低壓背壓閥描述：

德國LOCKE洛克進(jìn)口低壓背壓閥又稱背壓調(diào)節(jié)器（也叫背壓閥），采用膜片類型，具有高敏的特點(diǎn)。設(shè)計(jì)用來針對對流路進(jìn)行精確的壓力控制。相對于安全閥和普通的背壓閥的粗略壓力控制，其精度更高。進(jìn)口低壓背壓可以控制的最高壓力不能超過220PSIG(15Bar)，這一點(diǎn)是和膜片的承壓有關(guān)的。

The imported low-pressure back pressure valve of Locke lock, also known as back pressure regulator (also known as back pressure valve), is of diaphragm type and has high sensitivity. Designed for precise pressure control of the convection path. Compared with the rough pressure control of safety valve and common back pressure valve, its precision is higher. The maximum pressure that can be controlled by the inlet low-pressure back pressure cannot exceed 220psig (15bar), which is related to the pressure bearing of the diaphragm.

二、進(jìn)口低壓背壓閥結(jié)構(gòu)特點(diǎn)：

有遠(yuǎn)大于閥座密封面積的超高靈敏度膜片，產(chǎn)生極小的從開啟壓力到再密封壓力壓差，以及杰出的可重復(fù)性。

錐形閥桿保證與石墨填充聚四氟乙烯閥座完美的配合，不但實(shí)現(xiàn)在所有再密封壓力下氣泡法關(guān)閉，還因材料的低冷流動(dòng)性而具有在更高交變溫度下更好的閥座密封持久性。

There are ultra-high sensitivity diaphragms far larger than the sealing area of the valve seat, which can produce a very small pressure difference from the opening pressure to the resealing pressure, as well as outstanding repeatability.

The tapered stem ensures a perfect fit with the graphite filled polytetrafluoroethylene valve seat, which not only achieves bubble closure under all resealing pressures, but also has better seat sealing durability under higher alternating temperature due to the low cold fluidity of the material.
