定比减压阀 - 61系列 Ratio Reducing Valves - Code 61

派克的 Conflow 代号 61 - 定比减压阀用于, 在地下矿井底部, 在液流分配到全矿之前, 提供其下游的减压压力。 The Code 61 is a compact, in-line ratio reducing valve which reduces downstream fluid pressure to create safe and appropriate pressure for equipment to operate.

派克Conflow的Code 61是一种紧凑的在线比例减压阀，可将下游流体压力降低至安全且适当的压力，以使设备运行。 它可以按设定的比例和固定的比例有效地降低地下矿井中的下游流体压力，而无需考虑入口压力的变化。 Parker Conflow's Code 61 is a compact, in-line ratio reducing valve which reduces downstream fluid pressure to safe and appropriate pressures for equipment to operate. It is effective in reducing downstream fluid pressure in underground mines by a set proportion and to a fixed ratio, making no allowance for inlet pressure variations.

它的在线设计降低了损坏阀门的风险，并且还非常坚固-高压版本由不锈钢制成。 Its in-line design reduces the risk of damage to the valve and it is also extremely robust – the High Pressure version being manufactured from stainless steel.

Code 61阀门是入口压力相当恒定或需要降低压力但无需严格保持压力的选择。 在整个矿井中分布之前，它广泛用于竖井底部。 The Code 61 valve is ideal for use where the inlet pressure is fairly constant or where pressure reduction is required but does not need to be closely maintained. It is widely used at the shaft bottom, before distribution throughout the mine.

Code 61提供1/2“，1”，1 1/2“，2”，3“和4”四种尺寸，工作压力高达105 bar。 可以选择高达350 bar（1/2”）和206 bar（1”）的高压装置。 比率从入口压力的1.1：1降低到20：1。 Code 61 is available in four sizes 1/2", 1", 1 1/2", 2", 3" and 4" and operates at a maximum working pressure of 105 bar. High Pressure Units can be selected up to 350 bar (1/2”) and 206 bar (1”). Ratio reduction is provided from 1.1:1 to 20:1 of inlet pressure.
