减压阀
Pressure Reducer
减压器是将气瓶内高压空气减至供气阀正常工作时所需的压力（0.7±0.25）MPa。无论气瓶内空气压力及使用者的呼吸频率如何变化，减压器均有一个稳定的压力输出。
The function of pressure reducer is to reduce the high-pressured air in the air cylinder to be (0.7±0.25) MPa which is the proper functioning pressure of demand valve. No matter how the air pressure in the air cylinder and breathing frequency of users change, pressure reducer always has a stable pressure output.
不论气瓶的压力为多少，加压阀的输出压力始终处于0.6到0.9Mpa之间。其输出流量大于1000l/min：充分保证呼吸着的呼吸量。
Output pressure from 90psi to 135 psi (6bar to 9bar), Air flow≥1000L/min
减压阀重的安全阀是保护中压输出压力值的，当减压阀出现故障时，安全阀将自动开启，其开启的压力是0.99到1.5Mpa，安全阀关闭。
Safety valve will automatically operate while the valve fails. Safety valve can keep the output pressure from 148psi to 225psi (9.9bar to 15bar)
减压阀和供气阀的连接处装有限流孔，一旦压力表或高压管损坏，高压空气的损失流量不会超过25L/min。
There is a limited flow hole in valve connections, once the pressure gauge or pipe damage, the loss air flow no more than 25L/min

The Valve with safe self lock device is to avoid open or close air cylinder valve caused by collision or mishandle in operation. The hand wheel of air cylinder valve rotates anticlockwise to open and on the contrary to close. The air cylinder valve is set with safety membrane with bursting pressure of (37～45) MPa, which can prevent the air cylinder to be transformed and blasted because of too high pressure in the cylinder.

报警哨及压力表
Pressure Indicator and Alarming Device
压力显示是采用刻度（0～40）MPa 的压力表，它通过一根高压导管与减压器相连，表盘采用荧光材料，可在暗处观察压力表指示值。表面采用抗冲击材料，并设有橡胶保护套，有防水、防震和防尘功能，高压导管有限流装置，当压力表同其连接的高压导管脱开时，在气瓶压力为20MPa的情况下其漏气量不大于25L/min。
The pressure indicator is specified by scale ranged between（0-40）MPa, it is connected with the Reducer through a high pressure hose. The display panel is made of fluorescent material, which enables user to read the figure in darkness. The gauge surface is made of shock-resistant material, protected by rubber cover, waterproof, and dustproof. The high pressure hose is equipped with flow limit device, thus when the pressure gauge is separated from the high pressure hose, the air leaking volume should be no more than 25L/Min while the cylinder pressure is at 20MPa.
报警装置设在接近压力表的高压导管上，当气瓶中压力降低到（5.5±0.5）MPa时，报警哨会发出90dB(A)以上的连续报警声响。如果按报警压力值5MPa、气瓶容积6.8L、使用者呼吸的平均耗气量30L/min计算,则报警后尚可使用大约5-10分钟，不同气瓶容积报警后使用时间也是不同的。所以，使用者听到报警声应撤离现场，更换气瓶后方可继续工作。
The alarming device is on the high pressure hose near the pressure indicator. When cylinder pressure is below（5.5+ 0.5）MPa, the whistle will make about continuous 90d B(A) of noise. Working hours last another 5-10 minutes after warning, if we assume the alarming pressure at 5MPa, cylinder volume 6.8L, user average exhalation at 30L/min, it differs according to cylinder volume at the same time. Under such conditions, user must quit from dangerous place after hearing the alarm and is only allowed to continue to work after replacing with a new cylinder.The Warning Device is fixed on the high pressure pipe near the pressure gage. When the cylinder pressure reduces to (5.5±0.5) MPa, warning whistle will produce the continuous sounds over 90 dB(A). If the calculation is made according to the warning pressure value of 5 MPa, air cylinder volume of 6.8 L and users’ average gas consumption of 30 L/min, it can be used about 5-10 minutes after the warning and the using time of different cylinder volume differs after the warning. Therefore, users shall evacuate from the site after hearing the alarm and can continue to work after changing air cylinder
