RHZK自给开路式压缩空气呼吸器，（以下简称空气呼吸器）是一种正压式呼吸保护装置。

它配备有视野广阔、明亮、与面部贴合良好、气密的全面罩。

使用过程中，全面罩内的压力始终大于周围的大气压力，因此佩戴RHZK空气呼吸器安全可靠。

空气呼吸器在佩戴时左胸前设有余压警报器，当气瓶压力在规定标准以下时，可向佩戴者发出声响信号，便于使用人员及时撤离现场。

由于余压报警器在佩戴者胸前，即使现场有多台空气呼吸器发出报警音响，也能非常方便地区分是谁佩戴的空气呼吸器警报器报警，增强了产品使用安全性。

1检查气瓶压力及系统气密性检查：逆时针方向旋转瓶阀手轮，至少2圈。

如果发现有气体从供气阀中流出，则按下供气阀上有橡胶罩保护的节气开关，气流应停止。

30秒后，观察压力表的读数，气瓶内空气压力应不小丁28MPa。

压下手轮顺时针旋转瓶阀手轮，关闭瓶阀(见图9a)，继续观察压力表读数1分钟，如果压力降低不超过0 .5Mpa，且不继续降低，则系统气密性良好。

图9关闭瓶阀瓶阀使用方法：开启时用右手逆时针旋转手轮至少两圈，以完全打开瓶阀，关闭时用右手沿瓶阀体方向推进手轮，同时顺时针转动手轮，一次关闭不了，可重复关闭几次，直至完全关闭瓶阀。

(见图9b)注意：如果供气阀上的节气开关在瓶阀打开之前没有被按下关闭，空气将从面罩内自由流出。

如果气瓶未充满压缩空气，使用前须换上充满空气的气瓶。

2．检测报警器检查：压下于轮顺时针旋转瓶阀于轮，关闭瓶阀。

然后，略微打开供气阀上冲泄阎旋钮，将系统管路中的气体缓慢放出，当气瓶压力降到5~6MPa时，报警器应开始起呜报警，并持续到气瓶内压力小于1MPa时止。

待气流停止时．完全关闭冲泄阀(旋钮上的凸筋朝上)。

△警告：当气瓶压力降到5~6MPa时，如果报警器不能正常报警，则该装具暂停使用，并做好标记等待授权人员修理。

3.检查瓶箍带是否收紧用手沿气瓶轴向上下拨动瓶箍带，瓶箍带应不易在气瓶上移动，说明瓶箍带已收紧（见图10）。

如果未收紧，应重新调节瓶箍带的长度，将其收紧。

4.佩戴装具将气瓶底部朝向自己：然后展开肩带，并将其分别置于气瓶两边。

两手同时抓住背架体两侧。

并将空呼器举过头顶；同时。

两肘内收贴近身体，身体稍微前倾，使空呼器自然滑落于背部，同时确保肩带环顺着手臂落在肩膀上（见图11a）；然后，站直身体，向下拉下肩带，将空呼器调整到舒适的位置，使肩部承重。

（见图11b）5.收紧要带将腰带上的腰扣B捅入腰扣A内，然后将腰带左右两侧的伸出端同时向侧后方拉动，将腰带收紧。

(见图12)注意：使用空呼器时，如果没有按本说明书所述的扣紧和调节肩带、腰带，空呼器可能在使用者的身上移动或从身上掉下来，这将影响脸部与面罩的密封，并会使使用者暴露于危险环境中。

RHZK系列自给正压式空气呼吸器使用说明1.呼吸器的佩戴和使用。

1.1呼吸器使用之前的检查。

本呼吸器在使用前，气瓶内必须有足够的空气（一般在28—30MPA）。

1.2呼吸器的检查。

检查气瓶与背板是否连接可靠；检查气瓶内是否有足够的气体，（一般在28-30MPA）能否满足工作的需要；气密性检查：将供气阀两侧的开关向上推开，然后慢慢的打开气瓶阀至少2圈，使系统内充满压力，此时会听到一声短促的报警声响，允许呼吸器有10秒钟的升压，检查压力表的显示压力，是否会听到漏气声。

关闭气瓶阀并观察压力表指示，1分钟内压力下降值不超过2MPA。

若气密性检查不符合要求，则立即关闭气瓶阀，旋开供气阀上的红色旋钮，释放系统内气体。

检查各连接处（重点是气瓶连接）。

重复进行气密性检查；检查报警压力，打开气瓶阀，待系统内充满压力后立即关上，戴上面罩，然后缓慢呼吸，同时观察压力表，在5.5±0.5MPA使报警器应开始报警，气哨声应清晰明亮。

2.佩戴呼吸器2.1携带呼吸器。

将呼吸器的背带、腰带及面罩头带完全松开；将气瓶阀向下，完全打开气瓶阀；右手穿过右肩带并向后旋转，左手臂穿过左肩带将两手的大拇指伸入拉紧带环内，将肩带拉下，直到肩背的合身，扣好腰带。

2.2佩戴面罩。

放松面罩下的二根颈带，拉开面罩网，先将下颚放进面罩鄂托内，将头网从头部的上前方向后下方拉下，将面罩密封处的头发捋顺，收紧下端的二根颈带；按下供气阀两侧的开关；深吸一口气以开启供气阀，然后进行正常呼吸；2.3正压测试。

把一只手指伸进面罩内应有气流流出，拿开手指，面罩再次密封。

2.4面罩密封测试。

关闭气瓶阀，屏气10秒钟，仔细听有没有泄漏声，并观察压力表，看压力值是否下降，测试后请立即打开气瓶阀；若面罩密封测试失败，请立即打开气瓶阀，松开面罩系带，调整面罩并重新测试。

2.5性能测试。

通过几次深呼吸检查供气阀性能，吸气和呼气者应舒畅，无不适感觉。

2.6使用。

警告：在进入危险场所时，千万不要忘记按下供气阀两侧的开关。

正压式空气呼吸器使用说明一、用途SP-99正压式空气呼吸器(消防型号RHZK6．8／30型，以下简称呼吸器)是一种人体呼吸系统保护装置。

主要用于消防、化工、冶金、船舶、石油、矿山、实验室、仓库等部门，供消防队员或抢险救护人员在烟雾、毒气、粉尘或缺氧的环境中安全有效地进行灭火、抢险、救灾和救护工作。

本呼吸器是一种正压式呼吸保护装置。

面罩为全视野，视野宽阔、同时面罩内设双层密封保护，气密性好，佩带安全可靠；供给阀开闭灵活，供气量充足；余压报警装置紧凑地与压力警报器联为一体，配备在使用者的胸前，便于识别报警声响；减压器输出流量大，可保证输出充足的气体到供给阀。

本呼吸器吸取了国内外同类产品的优点，具有体积小、质量轻、操作简单、安全可靠、维修方便，佩带舒适等特点。

本呼吸器的技术性能完全符合GAl24《正压式消防空气呼吸器?和GBl6556《自给式空气呼吸器》ENl37、138的标准要求．二、规格及主要技术参数三构原理及主要部件1．结构原理本呼吸器由面罩、供给阀、减压器、快速接头、气瓶、背托、背具等部件组成。

本呼吸器采用气瓶自带压缩空气为气源，呼吸气流的流通方式是自给开放式。

当佩带者带上本呼吸器吸气时，新鲜空气由气瓶，经气瓶开关、减压器、中压导管、供给阀、面罩，被吸入到人的肺中；呼气时，呼出气体通过面罩上的呼气阀排到外界环境大气中，至此完成了一次呼吸循环过程，依次呼吸循环，直至工作结束。

在这个呼吸过种中，吸人气体靠供给阀控制输出量，由于供给阀的工作一方面靠腔室内的气压平衡，另一方面靠弹簧的压力调节，供给阀输出的气体量始终大于或等于被吸的气体量，所以保证了面罩内的气压始终不小于外界环境的大气压力(面罩内的正压范围在3—3．5毫巴)这是本呼吸器为正压式呼吸器的关键。

2．主要部件2．1面罩本呼吸器的面罩为全视野面罩，下视野更加宽阔。

双层环状片密封．面罩内设有与口鼻相贴合的小口鼻罩，口鼻罩上设有两个单向通气活门，下颊处有传话膜片。
