產(chǎn)品說明

The Type-700BP Back Pressure Regulator is a high flow, highly accurate pneumatic relief valve with an adjustable set point. It'sprimary function is to provide protection against over pressurization in the downstream portion of a pneumatic system. This precision unit is capable of handling flows up to 50 SCFM. A rolling diaphragm provides the sensitivity that causes the Type-700BP to vent to atmosphere in response to the slightest upstream changes. FEATURES • SENSITIVITY - Provides quick response to controlled system pressure variation. • HIGH FLOW CAPACITY - Flows up to 50 SCFM (depending on set point pressure and port size). • COMPENSATING FLOW CONTROL - Venturi type velocitypressure tube adjusts main control valve opening in accordance with velocity pressure variations of flow from controlled system. • ON-LINE MAINTENANCE - Unit can be disassembled and serviced without removing from the air line. APPLICATIONS The Type-700BP is used in place of a standard relief valve to provide protection against excessive build-up in supply pressure lines to instruments and other sensitive control devices. The most common application is to control the air pressure in a system supplied by a compressor. Used in conjunction with a diaphragm operated inlet restricting valve and a bleed orifice, the Back Pressure regulator relieves excess compressor pressure while activating the intake restricting valve. When the regulator shuts off, the down-stream air vents through the bleed orifice allowing the restricting valve to open.

700BP系列產(chǎn)品簡介：
精密背壓式調(diào)壓閥700BP是一種高流量、高精度氣動(dòng)安全閥，設(shè)定點(diǎn)可調(diào)。它的基本功能是對(duì)氣動(dòng)系統(tǒng)的下游壓力進(jìn)行過壓保護(hù),該減壓閥流量處理能力高達(dá)50SCFM。上游微小的壓力變化滾動(dòng)隔膜的靈敏度會(huì)引起該減壓閥向大氣中排放。
產(chǎn)品特點(diǎn)：
文氏對(duì)控制系統(tǒng)壓力變化反應(yīng)迅速
大流量：流量高達(dá)50 SCFM (依設(shè)定點(diǎn)壓力和接口尺寸而定)
流量補(bǔ)償控制：文氏流速壓力管根據(jù)控制系統(tǒng)流量流速壓力變化調(diào)節(jié)主控閥開啟進(jìn)行流量補(bǔ)償
在線維護(hù)：不用拆卸供氣管線就可方便維護(hù)
應(yīng)用：
適用于供壓管線到儀表和其它靈敏控制儀中的過壓保護(hù)。zui普通的應(yīng)用是空壓機(jī)供壓系統(tǒng)中的介質(zhì)壓力控制。用隔膜式入口節(jié)流閥和排氣孔，背壓減壓閥釋放過多的空壓機(jī)壓力，同時(shí)關(guān)閉入口節(jié)流閥。當(dāng)背壓減壓閥關(guān)閉時(shí)，下游介質(zhì)通過排放孔釋放并開啟該節(jié)流閥。
