1、 施工前注意事项 ① 埋地深度依照燃气施工规定，若埋地深度超过施工规定时，必须使用保护管。 ②
挖掘后先把石头，碎石等杂物xx，之后用沙子10cm厚左右铺平并压好。 ③ 球阀与连接结的配管需保持水平， 垂直状态后施工。 ④
与其它埋设物应保持埋设间隔距离。 · 地域采暖等 60℃以上 埋地物 ： THP等 利用保护措施后距离要保持30cm 以上 ·
上水管， 电气设施物， 通信 电缆线 ： 30cm 以上 · 下水管 ： 20cm 以上 2、球阀 使用说明书 对接熔接使用时 1)
要确认安装球阀的地理位置
地面有水或湿气的时，变更安装位置或把水或湿气xx去除后，保证地盘不下沉，必须把地基压结实，此时再把管调节到与地面成水平的位置 2)
管材的一端先固定到熔接机后打开球阀的包装，把球阀的一端固定上，如果对接焊接机的固定长度不充分，无法固定球阀时就使用两台固定机固定，球阀的另一端与固定机调到相同高度
固定→面加工→加热板安装→加压熔接→加热维持→接合→冷却→熔接机分离 3) 另一端的管固定好后按焊接方法进行焊接 注： ①
要作业时球阀上侧的标识箭头必须与燃气的流向一致 ②焊接作业中为了防止球阀内流入异物质使用包装袋等把球阀的内面堵住 ③
管与球阀要水平垂直状态熔接 4) 焊接机分离后 约需30分钟冷却 5）把"T"型球阀
把手从盒子中取出、组装完后，再把把手xx的插入到旋钮中 注：使用 "T"型 把手要测试球阀的开关状态 6) 要确认球阀有无开关动作
球阀的 ADAPTER直线 PE管材 长度和方向必须标(- )此时是开启的状态 直线垂直方向标 ( ‖)此时是关闭状态
关闭(CLOSE) ： 在开的状态下 把ADAPTER按顺时针的方向旋转 90° 打开(打开) ： 在关闭的状态下把
ADAPTER按逆时针的方向旋转90° GEAR BOX的TOP ADAPTER룰
180°左右，回转 箭头90°开关动作xx关闭状态(FULL CLOSE)， xx打开状态(FULL 打开) 状态不能冲劲开启或闭合
7) 使用放散球阀 气密试验 8) 球阀旋钮周边使用沙子 铺设 3、 使用电熔套筒 1） 要确认安装球阀的地理位置
地面有水或潮气时请改变安装的位置或把水或潮气xx的去处，为保证地盘不下沉。必须把地基压结实，此时再把管调节到与地面成水平的位置 2）
管 确认管切断时是否直角，未成直角时应重新切断 3） 刮球阀和管的表面
球阀的连接管表面和管表面，插入连接管时长度约20%的部位做标记，标记部位必须全部刮到，刮的厚度为0.2mm、管面刮完后，把连接套筒的包装拆除，把管xx插入到连接管内。（把连接管STOPPER键拆除后插入）
注：刮管表面是用连接套筒最重要的工程，所以管表面必须刮干净 4） 把球阀安放在埋设位置后，把管材标记位置插入到连接套筒 5）
另一端的管固定好后按熔接方法进行焊接 注：要作业时球阀开关的标识箭头必须与燃气的流向一致
焊接作业过程中为防止球阀内流入异物，使用包装袋把球阀内面堵住管与球阀要水平垂直状态下焊接 6） 焊接机分离后约需30分钟冷却 7）
把“T”型球阀把手从盒子中取出，安装完球阀后，用把手xx的插入到旋钮中 注：使用“T”型把手要测试球阀的开关状态 8） 要确认球阀开关
球阀的ADAPTER直线PE管材长度和方向必须标（-）时是开启状态，直线垂直方向标（‖）时是关闭状态
关闭（CLOSE）：在开的状态下把ADAPTER按顺时针方向旋转90度
打开（OPEN）：在关闭状态下把ADAPTER按逆时针方向旋转90度 齿轮箱的开关回转180度左右，箭头90度开关动作
xx关闭状态（FULL CLOSE）。xx打开状态（FULL OPEN）状态下不能冲劲开启和闭合 9） 使用放散球阀做气密试验 10）
球阀旋钮周围用沙子铺设 4、 阀气密实验方法 a) 关闭球阀 b) 安装放散球阀箱中附带的气密试验附件 c) 打开放散球阀 d)
使用压力发生气（室素燃气、气泵等）把管连接到气密试验工装上，把压力注入到球阀内后，关掉放散阀（试验压力1公斤以下） e)
把压力器从放散球阀分离后连接到压力实验机上 f) 打开放散球阀
使用连接后气密泄漏检查机检查，有或无泄漏的情形时关闭放散球阀，不在发生泄漏时在打开放散球阀 g)
连接后的气密压力过一定时间后，确认压力是否减少 压力xx减少后再次检查气密机连接部位有无泄漏。 5、 燃气泄漏检查机的使用方法
球阀必须在关闭的状态下连接
燃气接通状态下{jd1}不可以打开球阀，两侧已通气时无法用燃气泄漏检测仪器检测，暂定已经通燃气的部位为球阀的左侧，没通燃气的部位为右侧。
1） 打开球阀上侧的放散球阀 2） 打开燃气泄漏实验机检查燃气的浓度是否是零状态 3） 在放散球阀内插入燃气泄漏试

1, pre-construction Notice ① Buried deep gas construction in
accordance with the provisions of, if buried deeper than the
construction requirements, you must use the protective tube. ②
excavation should first stone, gravel and other debris removal,
after which paved with sand about 10cm thick and the pressure well.
③ valve and connecting piping junction to keep their horizontal and
vertical state after construction. ④ and other burial objects
should be kept away from laying interval. * Geographical heating
above 60 ℃ buried surface features such as: THP such as the use of
protection measures the distance to maintain more than 30cm * On
the plumbing, electrical facilities, materials, communications,
cable: 30cm or more * Pipe: 20cm or more 2, valve manual Butt
welding use 1) To confirm the installation location of ball valve
The ground when water or moisture, change the installation
location, or to complete after the removal of water or moisture to
ensure that construction sites do not sink, the foundation must be
strong pressure at this time then regulated to control the level
with the ground the location of 2) The first fixed to one end of
pipe welding machine and opened the valve of the package, the ball
of one end fixed, if the butt welding machine of the fixed length
is not adequate, can not be fixed ball machine on the use of two
fixed-fixed, ball valve the other end of the fixed machine
transferred to the same height → Fixed installation of heating
plate surface processing → → → heat to maintain pressure welding
joints → → cooling → welding machine Separation 3) The other end of
the tube and fixed by welding after the welding method Note: ① to
work when the ball valve on the side of the identity arrows must be
consistent with the gas flow ② welding operations in order to
prevent the ball into the different material the use of packaging
bags such as the ball inside the block ③ pipe and valve to the
level of vertical welding 4) The welding machine takes about 30
minutes after the separation cool 5) to "T"-type ball valve handle
removed from the box, assemble finished, then fully inserted into
the handle knob of Note: Use the "T" type handle to test the valve
in the switch state 6) To confirm whether the switch valve action
Ball Valve ADAPTER linear PE pipe length and the direction must be
marked (-) is turned on at this time the state of Vertical line
marked (‖) is closed at this time Close (CLOSE): In the open state
ADAPTER clockwise direction to rotate 90 ° Open (Open): In the
closed state to ADAPTER by 90 ° counter-clockwise direction of
rotation GEAR BOX's TOP ADAPTER 룰 180 ° or so,
turn arrows 90 ° switching action completely off (FULL CLOSE),
fully open state (FULL open) state can not drive to open or close
7) The use of diffuse gas-tight ball valve test 8) valve knob
surrounding the use of sand to lay
3, using fused sleeve 1) To confirm the installation location of
ball valve The ground water or moisture when you change the
installation location, or to water or moisture of the place
completely, in order to ensure that construction sites do not sink.
Foundation must be strong pressure at this time then regulated to
control the level with the ground the location of 2) tube To
confirm whether the pipe cut off at right angles to unsuccessfully
to cut off at right angles should be re - 3) scraping the surface
of ball valves and tubes Valve of the connecting pipe surface and
tube surface, inserting connecting pipe length of about 20% of the
parts marking, labeling parts must all be blown to, scraping the
thickness of 0.2mm, tube surface Guawan after the removal of the
connecting sleeve of packaging and the possession fully inserted
into the connecting pipe. (The connecting pipe STOPPER key removed,
insert) Note: The scraper tube surface is used to connect sleeve of
the most important projects, so pipe surface must be Guagan Jing 4)
the ball placed in the burial location, the location of pipe marker
inserted into the connection sleeve 5) The other end of the tube
and fixed by welding after the welding method Note: To work when
the valve switches the identity of the arrow must be consistent
with the gas flow Soldering process to prevent the ball inside the
inflow of foreign body, the use of packaging bags to block the tube
and inside ball valve welded to horizontal and vertical state 6)
The welding machine takes about 30 minutes after the separation
cool 7) to "T"-type ball valve handle removed from the box,
installed after the ball, with handle fully inserted into the knob
in the Note: Use the "T" type handle to test the valve in the
switch state 8) To confirm that the ball valve switch Ball Valve
ADAPTER linear PE pipe length and the direction must be marked (-)
when turned on, a straight line perpendicular to the direction of S
(‖) when turned off Close (CLOSE): In the open state of the ADAPTER
rotate 90 degrees clockwise Open (OPEN): In the off state to rotate
90 degrees counter-clockwise direction ADAPTER Gear box rotary
switch 180 degrees, the arrow moves 90 degrees Switch Completely
off (FULL CLOSE). Fully open (FULL OPEN) state can not be
aggressive opening and closing 9) The use of elution test valve so
gas-tight 10) the laying of sand around the ball valve knob 4,
valve airtight experimental methods a) Close valve b) installation
of emission of gas-tight valve box with test accessories c) Open
the diffuse ball d) use of pressure occurring gas (room prime
natural gas, air pump, etc.) to connect to a gas-tight test tube
tooling on the pressure is injected into the ball inside the post,
turn off the Bleeding valve (test pressure of 1 kg or less)
e) the pressure device separated from the elution valve connected
to the pressure testing machine f) Open the diffuse ball Use
airtight leak inspection machines connected to check the situation
with or without leakage when the valve closure of diffuse, and not
leak when the valve opening diffuse g) connected to a gas-tight
pressure over a certain time, to confirm whether the reduction in
pressure Reduced pressure to completely re-examine whether the
leaking joints airtight machine. 5, gas leak check the machine to
use Ball must be in the closed state to connect Gas must not be
connected to a state of open ball valve, both sides have
ventilation when you can not use gas leak detection equipment test,
tentatively has been pass gas for the ball to the left of the site,
did not pass gas for the right side of the site. 1) Open the ball
valve on the side of the Bleeding 2) Open the gas leak tester
checks whether the concentration of gas-zero state 3) In the
diffuse gas leak test valve insert
